Recent Development—BioMarin Acquisition
 
On November 24, 2014 we entered into a purchase agreement with BioMarin Pharmaceutical Inc. BioMarin launched an initial offering period (tender offer) to purchase all of our issued and outstanding ordinary shares, nominal value €0.01 per share (the BioMarin Acquisition or the Acquisition). On January 15, 2015, BioMarin announced the completion of the previously announced offer (the Closing) by subsidiaries of BioMarin. Upon the Closing, BioMarin purchased 93.4% of our shares and immediately launched a subsequent offering period that expired on January 29, 2015. As of the expiration of the subsequent offering period, BioMarin paid approximately $659.3 million for approximately 34,970,514 of our shares, representing approximately 96.8% of all of our shares outstanding, and for options that vested pursuant to the definitive purchase agreement.
 
On February 5, 2015, we and BioMarin Falcons B.V. entered into an asset sale agreement that closed on February 12, 2015 (the Asset Sale), pursuant to which BioMarin Falcons B.V. or its designee acquired all of our assets and assumed all of our liabilities and paid $20.8 million to our remaining shareholders. On February 11, 2015, we filed a Form 25, Notification of Removal from Listing and/or Registration, under Section 12(b) of the Securities Exchange Act of 1934 with the Securities and Exchange Commission (the SEC) in order to voluntarily delist our shares from the NASDAQ Global Select Market, which became effective 10 days after filing. NASDAQ suspended trading of our shares after the market closed on February 11, 2015. BioMarin currently owns 96.8% of our outstanding share capital. Effective February 12, 2015, Prosensa Holding N.V. is in liquidation under Dutch law. We are filing this Annual Report on Form 20-F pursuant to our filing obligations that existed prior to the Acquisition and Asset Sale and do not intend to file any additional periodic reports with the SEC.
 
 
The summary income statement data for the years ended December 31, 2014, 2013 and 2012 of Prosensa Holding N.V. are derived from the consolidated financial statements included in this Annual Report. Until December 31, 2014, we maintained our books and records in euros, and we prepare our financial statements under International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”).

Our business, financial condition or results of operations could be materially and adversely affected if any of these risks occurs, and as a result, the market price of our ordinary shares could decline. This Annual Report also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially and adversely from those anticipated in these forward-looking statements as a result of certain factors.
 
Uncertainty following the Asset Sale could adversely affect our business and operations.
 
The completion of the Closing and Asset Sale could cause disruptions to our business and business relationships, which could have an adverse impact on our results of operations, liquidity and financial condition. For example, our current and prospective employees may experience uncertainty about their future roles with us that may adversely affect our ability to retain and hire key personnel, and parties with which we have business relationships, including customers, potential customers and distributors, may experience uncertainty as to the future of such relationships and seek alternative relationships with third parties or seek to alter their present business relationships with us in a manner that negatively impacts us.
 
BioMarin has the ability to make important decisions affecting our business and upon the effectiveness of our liquidation the shares of our company will be extinguished for no additional consideration.
 
As of April 15, 2015, approximately 96.8% of our ordinary shares were owned by BioMarin. As a majority holder of the voting shares, BioMarin is entitled to elect all of our directors, to approve any action requiring the approval of the holders of our ordinary shares, including adopting amendments to our articles of association and approving mergers or sales of substantially all of our assets, and to prevent any transaction that requires the approval of shareholders. BioMarin has effective control over our affairs, policies and operations, such as the appointment of management, future issuances of our securities, the payments of distributions by us, if any, in respect of our common stock, the incurrence of debt by us, and the entering into of extraordinary transactions, and BioMarin’s interests may not in all cases be aligned with the interests of investors. In addition, all future decisions regarding the development of our product candidates will be made by BioMarin and we will have no influence on that decision-making process. We are currently in liquidation, and upon the effectiveness of our liquidation, the shares of our company will be extinguished for no additional consideration.
 
We no longer intend to file reports with the Securities and Exchange Commission, which will reduce the amount of publicly available information about us and negatively affect the liquidity of our ordinary shares.
 
We filed a notice of termination of registration under Section 12(g) of the Exchange Act on March 23, 2015. As a result, our obligations to file reports under Section 12(g) of the Exchange Act with the SEC were suspended on such date and will terminate on June 21, 2015. We currently have no intention of filing any reports with the SEC in the future. In absence of filings with the SEC, there may be limited publicly available information available about us, which will likely reduce the liquidity of our ordinary shares and increase the risks of engaging in transactions in our ordinary shares.
 

 
If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud.
 
Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404 of the Sarbanes-Oxley Act of 2002, or any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement.
 
We are required to assess the effectiveness of our internal controls annually. However, for as long as we are an “emerging growth company” under the JOBS Act, our independent registered public accounting firm will not be required to attest to the effectiveness of our internal controls over financial reporting pursuant to Section 404. An independent assessment of the effectiveness of our internal controls could detect problems that our management’s assessment might not. Undetected material weaknesses in our internal controls could lead to financial statement restatements and require us to incur the expense of remediation.
 
 
 
Important Note
 
On January 15, 2015, BioMarin announced the completion of the previously announced offer by subsidiaries of BioMarin to purchase all of our issued and outstanding ordinary shares, nominal value €0.01 per share (the Acquisition). On February 5, 2015, Prosensa and BioMarin Falcons B.V. entered into an asset sale agreement that closed on February 12, 2015 (the Asset Sale), pursuant to which BioMarin Falcons B.V. or its designee acquired all of Prosensa’s assets and assumed all of Prosensa’s liabilities (the Post-Closing Reorganization). On February 11, 2015, we filed a Form 25, Notification of Removal from Listing and/or Registration, under Section 12(b) of the Securities Exchange Act of 1934 (the Form 25) with the SEC in order to voluntarily delist our registered shares from the NASDAQ Global Select Market, which became effective 10 days after filing. NASDAQ suspended trading of our shares after the market closed on February 11, 2015.
 
In conjunction with the Asset Sale, we made an advance liquidation distribution to our remaining shareholders, with each remaining shareholder receiving a cash payment equal to $17.75 per share as well as one contingent value right to receive cash payments of up to $4.14 per share in the aggregate upon the achievement of the right to market and sell drisapersen in the United States and in the European Union, without interest thereon and less any applicable withholding taxes. Following the Asset Sale and advance liquidation distribution, we have minimal assets, no further distributions are expected to be made and our ordinary shares are expected to have little to no value.
 
The Post-Closing Reorganization, including the Asset Sale and our subsequent dissolution and liquidation, is a process available to BioMarin under Dutch law to ensure that BioMarin becomes the owner of all of our business operations from and after the consummation of the Post-Closing Reorganization. The Asset Sale and our subsequent dissolution and liquidation will result in all holders of our ordinary shares that were not tendered in BioMarin’s offer being offered or receiving for each ordinary share then held cash and contingent value rights without interest and less applicable withholding tax and any other taxes. Stichting Prosensa, a foundation (stichting) organized and existing under the laws of the Netherlands, has been appointed as the liquidator to carry out the liquidation of the assets once our dissolution has become effective.
 
As a result of the Acquisition and Asset Sale, our ordinary shares are no longer publicly traded. Upon the filing of the Form 25, our obligations to file with the SEC periodic and current reports under the Exchange Act were suspended. We are filing this Form 20-F pursuant to our filing obligations that existed prior to the Acquisition and Asset Sale and do not intend to file any additional periodic reports with the SEC.
 
The Company
 

 
We are an innovative biotechnology company engaged in the discovery and development of ribonucleic acid-modulating, or RNA-modulating, therapeutics for the treatment of genetic disorders. Our primary focus is on rare neuromuscular and neurodegenerative disorders with a large unmet medical need, including Duchenne muscular dystrophy, myotonic dystrophy and Huntington’s disease. Our clinical portfolio of RNA-based product candidates is focused on the treatment of DMD. Six of our DMD compounds have been granted orphan drug designation in the US and the EU.  Drisapersen, our lead product candidate, has been granted orphan drug designation in the US, EU, Australia and Japan and has been granted breakthrough therapy designation by the FDA for the treatment of DMD.
 
DMD is one of the most prevalent rare genetic diseases globally affecting up to 1 in 3,500 boys and is invariably fatal. There is currently no approved disease-modifying therapy for DMD. The progressive muscle-wasting that characterizes this disease is caused by inadequate production of dystrophin, a protein necessary for muscle function, as a result of mutations in the dystrophin gene. The different mutations, which are mostly deletions of one or more exons, found in the dystrophin gene result in distinct sub-populations of DMD patients. We are designing product candidates to address several sub-populations using our platform technology. Drisapersen aims to address a variety of mutations in the dystrophin gene, such as a deletion of exon 50 or exons 48 to 50 and may address up to 13% of all DMD patients.
 
Drisapersen, which has previously been referred to as PRO051 or GSK2402968, was advanced through clinical development as part of a collaboration with GSK dating back to 2009. This collaboration was mutually terminated in January 2014, and we fully retain all licenses and rights to drisapersen and our DMD portfolio.
 
On October 10, 2014, we commenced the submission of a NDA for drisapersen with the FDA under an accelerated approval pathway based on existing data. This submission followed our receipt of positive feedback from a meeting with the FDA that took place on May 14, 2014. In addition, we have been interacting with the EMA, and based on these interactions we also intend to file for conditional approval in Europe.  On April 27, 2015, BioMarin announced completion of the rolling submission of the NDA to the FDA for drisapersen.
 
Drisapersen aims to restore dystrophin expression and improve muscle condition and function in the largest known sub-population of DMD patients. In clinical trials, drisapersen has been shown to produce novel dystrophin expression and have a beneficial therapeutic effect on DMD patients. We conducted a Phase I/II dose-ranging safety study in which drisapersen was administered to 12 patients subcutaneously, once weekly for 5 weeks. The study, initiated in March 2008 and conducted at two European clinical centers, demonstrated that drisapersen was well-tolerated in all patients and novel dystrophin expression was detected in each treated patient. An open-label extension study (DMD114673) of this Phase I/II study was initiated in August 2009 and patients have continued in this study for over four years, with efficacy results available up to 177 weeks and safety results up to 188 weeks. The mean change from baseline for the 10 boys that were able to walk at the beginning of the study after 177 weeks was -25 meters.
 
A Phase II placebo-controlled study (DEMAND II/DMD114117) of drisapersen in 53 DMD patients was completed and demonstrated a statistically significant and clinically meaningful difference in the primary endpoint, which was the distance walked in the six minute walk test, or 6MWD, between the placebo group and the continuous active-treatment group at a dose of 6 mg/kg/week after 24 weeks. This clinically meaningful benefit was maintained after 48 weeks of treatment, and drisapersen was well tolerated throughout the duration of this study. The data were presented at a scientific meeting in April 2013, and the detailed study results were published in the Lancet Neurology, a peer reviewed journal, in September 2014.
 
Results from a U.S.-based Phase II placebo controlled exploratory study (DEMAND V/DMD114876) of 24 week dosing of drisapersen 3mg/kg/week and 6mg/kg/week were presented on September 25, 2013. The results of this study indicate that, compared to placebo, boys in the higher-dose drisapersen group (6 mg/kg once weekly) experienced stabilization and even improvements in their muscle function and physical activity as measured by the six-minute walk test (6MWT) for the 24-week treatment phase. Boys in the 6mg/kg/week treatment arm showed a 27.1 meter improvement (including a 16.1 meter increase from baseline) over the boys in the placebo group at the end of the treatment period (p=0.069), ), indicating a clinically meaningful outcome for the primary endpoint. The study was not statistically powered to show a significant difference between the arms.
 
The 48 week data from this study were presented on March 17, 2014 by Craig McDonald at a poster session at the Muscular Dystrophy Association 2014 Clinical Conference in Chicago, IL. A clinically meaningful treatment difference of 27.9 meters over placebo (p=0.177) was maintained for 24 weeks after drisapersen administration
 

 
ceased. This includes an overall mean increase from baseline of 14.7 meters. In the drisapersen 6 mg/kg/week group, an improvement was seen in the percent-predicted 6MWD of 5.25% (p=0.051) and 4.85% (p=0.154) when compared to placebo at weeks 24 and 48, respectively.
 
A Phase III study of drisapersen (DEMAND III/DMD114044) was initiated in December 2010, and results were announced on September 20, 2013. This study was a randomized, double-blind and placebo-controlled trial, assessing drisapersen at a dose of 6 mg/kg/week in 186 boys. The study did not meet its primary endpoint of statistically significant difference in the 6MWD at 48 weeks. As a result, GSK suspended dosing in all pending a full evaluation of the benefit-to-risk profile of drisapersen treatment across all studies.
 
In January 2014, we announced findings from subjects who had reached 48 weeks treatment in study DMD114349, an open-label continuation study to follow the placebo-controlled drisapersen studies DMD114117 and DMD114044. At 48 weeks in study DMD114349, there was a treatment difference of 46.1 meters (n=113) when comparing subjects treated with drisapersen at 6mg/kg/week (n=69) throughout both studies, versus subjects who had received placebo (n=44) prior to initiating the open-label continuation treatment period.  Subjects enrolled from study DMD114117 showed a treatment difference of 52 meters (n=30) when comparing subjects treated with drisapersen at 6mg/kg/week (n=17) throughout both studies, versus subjects who had received placebo (n=13) prior to initiating the open-label continuation treatment period. For subjects enrolled in study DMD114349 from study DMD114044, the treatment difference at 48 weeks in study DMD114349 was 49 meters (n=83) for those dosed at 6mg/kg/week throughout (n=52) versus subjects previously allocated to placebo treatment (n=31) in study DMD114044.
 
In combination with the positive feedback from patients and investigators regarding the willingness and desire of patients to resume treatment with drisapersen, we have commenced a comprehensive re-dosing program for all patients previously treated with drisapersen, with the first patients re-initiating treatment in the United States, Canada and Belgium in September 2014.
 
PRO044 addresses a separate sub-population of up to 6% of DMD patients. We developed PRO044 using our exon-skipping technology to generate a product candidate with the same mechanism of action as drisapersen. PRO044 has completed a Phase I/II study in Europe, and results were presented in October 2013. We have four additional compounds that address other distinct sub-populations of DMD patients: PRO045 and PRO053 (each addressing a population of up to 8% of all DMD patients) and PRO052 and PRO055. We are also developing PROSPECT, which employs multi-exon skipping induced by a single antisense oligonucleotide and is initially designed to address mutations in the exon 10 to 40 region.
 
We started operations in 2002 and are located in Leiden, the Netherlands. We work closely with Leiden University Medical Center, or LUMC, with whom we entered into an exclusive licensing agreement in 2003 for LUMC’s proprietary RNA modulation exon-skipping technology to develop treatments for DMD, other neuromuscular disorders and indications outside the field of neuromuscular disorders. In 2013, we conducted an initial public offering of our ordinary shares on Nasdaq.  On November 23, 2014, we entered into a definitive purchase agreement with BioMarin to be acquired by BioMarin.  See “—Important Note.”

Our RNA-modulating therapeutics
 
Human genes contain the DNA blueprint instructions for protein synthesis and gene regulation in the body. Within the DNA strand, multiple series of three-letter nucleotide bases (known as “codons”) together make up the active instruction units called “exons,” which are read by cellular machinery to make proteins. Interspersed among exons are sections of DNA known as “introns,” which are assumed to have no direct role in protein synthesis.
 
To make a particular protein, the relevant section of DNA is copied (in a process known as transcription) to make pre-mRNA (pre-messenger ribonucleic acid), which contains both exons and introns and therefore cannot be read by the cellular machinery as an instruction to make a protein. The introns are then removed (in a process known as splicing) so that the instructions in the active mRNA (messenger RNA) can be read by the cellular machinery to make a particular protein.
 
Schematic overview of RNA Synthesis
 
 
The dystrophin gene, which is central to the pathology of DMD, is comprised of 79 exons, which are interspersed with non-coding introns. In patients with DMD, synthesis of the dystrophin protein is disrupted because
 

 
of mutations in the DNA that contains the dystrophin gene. The extent and nature of the mutations are different in different sub-populations of DMD patients and may be due to, among other things, deleted or duplicated exons or small mutations that result in disrupted coding of the mRNA. This defective mRNA is said to be “out of the reading frame” and results in a premature halt of the protein synthesis and a truncated, non-functional dystrophin. Consequently, patients with DMD have a lack of functional dystrophin protein in their muscles. Our aim is to restore the coding reading frame of mRNA so that it can be read to produce a largely functional dystrophin protein.
 
Our technology enables us to design sequences of nucleotide bases that bind to specified regions of pre-mRNA involved in the splicing of exons. As a result, when the pre-mRNA is spliced to mRNA, the disrupted coding section is skipped or passed over completely, and the reading frame is corrected. The single stranded oligonucleotides (short nucleotide sequences) that we design are known as antisense oligonucleotides, or AONs; and our preferred chemical structure is a backbone of 2’ O-methyl phosphorothioate (or 2’O-Me) groups that protect the AONs from rapid enzyme degradation once they are inside the body’s cells. In DMD, we apply this technology to address particular mutations occurring at different sites in the dystrophin gene.
 
Our RNA modulation platform technology can also be applied to treat genetic disorders that are caused by mutations where trinucleotides, such as CAG or CUG, are expanded in certain genes, generating a longer series of trinucleotide repeats than is normal. These extended repeated sequences can cause the resulting RNA transcript or protein to be unstable, dysfunctional or even toxic, and lead to various diseases. We currently have AON programs targeting two such disorders, Huntington’s disease and myotonic dystrophy.
 
Overview of DMD
 
DMD is a rare, severe muscle wasting disease that occurs in up to 1 in 3,500 male births. It is commonly diagnosed between the ages of three to five, when boys begin to show signs of impaired motor development. Boys with DMD continue to develop in strength and function, albeit at a lower rate than healthy boys, up until about 7 years. They then begin to progressively lose muscle function, generally becoming wheelchair-bound around the age of 12, with loss of respiratory and cardiac function in the ensuing years. DMD patients typically die in their twenties of either cardiac or respiratory failure.
 
Currently, there is only one approved disease-modifying treatment for DMD that has conditionally been approved in Europe, Translarna, which is indicated for a different genetic subpopulation of DMD patients than our portfolio aims to address. Corticosteroid therapy is the current standard of care in most developed countries and may be administered as early as 3 years, although administration commonly starts at 4-6 years. Steroids have been demonstrated to temporarily preserve muscle function and delay disease progression milestones, such as time to wheelchair dependency, by approximately 2 years, but the ultimate course of the disease is unaffected. In addition, steroids have potentially serious side effects, negatively affecting growth, bone mineral density and the immune system.
 
DMD is caused by various mutations in the dystrophin gene, such as deletions, duplications or small mutations of one or more exons, which result in a lack of functional dystrophin in the muscle fiber. Dystrophin is a protein with a central role in linking the contractile apparatus of a muscle fiber to the cell membrane and surrounding extracellular matrix. An absence or a low level of dystrophin also leads to reduced levels of various other proteins. This leads to progressive muscle fiber degeneration characteristic of DMD, with fatty and fibrous tissue replacement of muscle.
 
Deletions of any number of exons in the dystrophin gene may occur. The different mutations result in distinct sub-populations of DMD patients. The figure below shows the effect of the deletion of exons 48 – 50 in the dystrophin gene.
 
Effect of a deletion of exons 48-50 in the dystrophin gene
 
 

 
In this example, the deletion of exons 48—50 results in an mRNA that is out of the transcription reading frame since exons 47 and 51 do not fit together. Consequently, functional dystrophin will not be produced.
 
Exon skipping technology applied to DMD
 
Our therapeutic strategy for DMD is to use AON-induced exon skipping to allow a modified but still largely functional dystrophin protein to be produced so that muscle performance in patients with DMD may be maintained or even improved. Our AONs bind highly specifically to a selected exon in the pre-mRNA derived from the dystrophin gene. The exon is selected because it is, for instance, adjacent to a region where one or more exons have been deleted. As a result, the exon to which the AON binds is skipped over in the splicing process, allowing two non-consecutive exons to be joined across the gap. This results in what is termed “restoration of the reading frame”—in other words, the genetic instructions or code become legible again, and a modified but still largely functional dystrophin protein is produced. The figure below shows how an AON binding with exon 51 of the gene’s pre-mRNA can result in an in-frame mRNA transcript and production of a modified but still largely functional dystrophin protein.
 
Example of effect of drisapersen
 
 
In this example, there is a deletion of exons 48 to 50; drisapersen binds with exon 51 in the pre-mRNA, and after splicing, this results in exon 47 and exon 52 becoming consecutive exons in the mRNA. Since exon 47 and exon 52 connect properly, an in-frame mRNA results and a shorter but still functional dystrophin protein may be produced, which is expected to result in improved muscle physiology and hence clinical outcome.
 
Drisapersen
 
Our lead compound, drisapersen, is an AON with highly specific binding to exon 51 of the dystrophin gene’s pre-mRNA. The binding of drisapersen to exon 51 specifically induces exon 51 to be skipped when the mRNA for the dystrophin protein is created from the pre-mRNA. Given the frequencies reported in various international DMD mutation databases, the skipping of exon 51 could in principle correct the reading frame and produce shortened but functional dystrophin expression in approximately 13% of all DMD patients.
 
Drisapersen has been granted orphan drug designation in the United States, the European Union, Japan and Australia.
 
We demonstrated clinical proof of concept in four DMD patients receiving a single intramuscular 0.8 mg dose of drisapersen in a trial initiated in May 2006. In this study, drisapersen was safe and effective in specifically inducing exon 51 skipping and restoring dystrophin expression to 35% of normal levels in up to 97% of muscle fibers in the treated muscle area.
 
From October 2009 to January 2014, we operated under a collaboration agreement with GSK for the clinical development of drisapersen, and studies operated in this period were sponsored by, and under the sole budgetary decision-making of GSK. This collaboration was mutually terminated on January 12, 2014, and we have regained all rights for development and commercialization of drisapersen, including relevant intellectual property, and Prosensa’s DMD portfolio.
 
Other DMD compounds
 
One of our other exon skipping product candidates for DMD is PRO044, which, like drisapersen, is a highly sequence-specific AON that, in this case, induces exon 44 to be skipped when the mRNA for the dystrophin protein is created from the pre-mRNA. Given the frequencies reported in various international DMD mutation databases, the skipping of exon 44 could in principle correct the reading frame and produce shortened but functional dystrophin expression in approximately 6% of all DMD patients. PRO044 has obtained orphan drug designation in the United States and the European Union.
 

 
PRO045 has a similar chemical structure and the same mechanism of action as drisapersen and PRO044 and induces exon 45 skipping when the mRNA for the dystrophin protein is created from the pre-mRNA. Given the frequencies reported in various international DMD mutation databases, the skipping of exon 45 could in principle correct the reading frame and produce shortened but functional dystrophin expression in approximately 8% of all DMD patients. PRO045 has been granted orphan drug designation in the United States and the European Union.
 
PRO053 induces exon 53 skipping and could in principle correct the reading frame and produce functional dystrophin expression in approximately 8% of all DMD patients. PRO053 has been granted orphan drug designation in the United States and the European Union.
 
PRO052 and PRO055 induce exon 52 skipping and exon 55 skipping, respectively. Both have been granted orphan drug designation in the United States and the European Union and are currently in advanced preclinical development. Finally, our PROSPECT program, which includes a new and innovative application of our exon-skipping technology platform, multiple exon skipping, specifically targets rarer mutations (initially in the exon 10-40 region) in the dystrophin gene. This approach could have applicability for up to 20% of the DMD population. This program is still in the early pre-clinical phase.
 
Non-DMD compounds
 
Myotonic dystrophy type 1 (DM1) is the most common neuromuscular dystrophy, affecting 1 in 8,000 individuals worldwide. The disease affects males and females equally, and the severity of symptoms increases in successive family generations. There is currently no disease modifying treatment for DM1. Our AON program for DM1, PRO135, selectively targets the toxic RNA transcripts resulting from expansion of (CUG) trinucleotide repeats in the transcription of the DMPK gene. We have exclusive worldwide rights to the PRO135 program, and we are fully responsible for its research and development.
 
Huntington’s disease (HD) is a devastating progressive neurodegenerative disorder characterized by chorea (abnormal involuntary movement) spreading to all muscles, progressive dementia and psychiatric manifestations such as depression and psychosis. In western countries, prevalence is estimated to be 5-10 in 100,000 individuals. No effective disease modifying treatment for HD currently exists. Our AON program for HD, PRO289, is in preclinical development. We have exclusive worldwide rights to PRO289 and are fully responsible for its research and development. PRO289 has been granted orphan drug designation in the United States.
 
Collaboration, license and funding arrangements
 
GlaxoSmithKline
 
From October 2009 to January 2014, we operated under an exclusive worldwide collaboration with GSK for the development and commercialization of RNA-based therapeutics for DMD, with GSK exclusively licensing worldwide rights to develop and commercialize drisapersen and obtaining an option to exclusively license PRO044 and other specified assets in our DMD portfolio. Under the collaboration agreement, GSK paid us a total of £41.5 million (€47.4 million) in upfront and milestone payments. Under the collaboration agreement, GSK was responsible for all costs of clinical development of drisapersen.
 
In January 2014, we and GSK mutually terminated the collaboration pursuant to a termination agreement, which terminated all intellectual property license grants as well as any rights arising under the collaboration agreement (other than rights to payments that accrued prior to termination of the collaboration). In addition, the termination agreement required GSK to transfer to us certain data and know how, inventory, regulatory filings, clinical trial sponsorships, clinical study reports and material agreements relating to the development of our products. We and GSK each agreed to indemnify the other party with respect to certain acts and omissions.
 
Leiden University Medical Center
 
In September 2003, we obtained an exclusive worldwide license from LUMC for the application of its proprietary RNA modulation exon-skipping technology to develop treatments for selected neuromuscular disorders. The license agreement gives us the rights to apply the RNA modulation technology for the development of treatments for neuromuscular disorders as well as, after an amendment of the agreement in March 2008, indications outside the field of neuromuscular disorders. We have also granted LUMC a non-exclusive, royalty-free license to certain intellectual property we own for the purpose of enabling LUMC to perform internal, non-commercial
 

 
research. The agreements with LUMC have been transferred to BioMarin as part of the Asset Sale. To date we have paid LUMC €3.6 million in milestone payments under the agreement.
 
Competition
 
We are engaged in segments of the biopharmaceutical and pharmaceutical industries that are highly competitive and rapidly changing.
 
We believe that our key competitor in DMD is Sarepta, a U.S. company focused on the development of their lead product candidate eteplirsen, which employs the same exon 51 skipping approach as drisapersen. PTC Therapeutics, Inc. developed Translarna (ataluren), which is indicated for a different genetic subpopulation of DMD patients than our portfolio aims to address. Translarna received conditional marketing authorization in the European Union in August 2014 for the treatment of ambulatory nmDMD patients five years and older.
 
In addition to the development programs described above, there are a number of drugs in development that could be complementary treatments to drisapersen or our other DMD product candidates and with whom which we may compete for patients to enroll in clinical trials. Asklepios Biopharmaceuticals, Inc. is developing biostrophin, a gene therapy approach, and Summit plc is developing a therapy to increase the production of utrophin (a dystrophin-like protein). Akashi Therapeutics, Inc. is developing HT-100, an oral analog of the antifibrotic halofuginone that acts as an inhibitor of type-I collagen synthesis and skin sclerosis and promotes myotube fusion, which is necessary for muscle regeneration. Different therapeutic approaches aiming at muscle tissue growth through myostatin inhibition are being investigated in clinical studies. These include PF-06252616 by Pfizer Inc. and ACE-031 by Acceleron Pharma.
 
In addition, corticosteroids are the current standard of care for DMD patients, although they do not address the underlying cause of DMD and have serious side effects. We believe that corticosteroids will continue to be prescribed in conjunction with any of our product candidates that obtain regulatory approval.
 
Manufacturing
 
We develop and manufacture the drug product for our initial preclinical studies using standardized manufacturing processes in our own laboratories. A selected number of Contract Manufacturing Organizations (CMOs) manufacture scaled-up quantities of the drug, based on our advice and know-how. We and the CMOs use multiple qualified suppliers for the raw materials, and the raw materials are widely commercially available from catalog.
 
Intellectual property
 
Until the completion of the Asset Sale, we owned or exclusively licensed U.S. patents, U.S. patent applications, European patents, European patent applications, international patent applications, and national patent applications or granted patents in other jurisdictions relating to our DMD program and our other discovery programs. All of our intellectual property was transferred to BioMarin as part of the Asset Sale.
 
Opposition proceedings against EP ‘249
 
In September 2008, EP 1619249 (‘249) was granted to LUMC. This patent relates to exon skipping using an oligonucleotide with a certain length, directed to the interior of a broad range of exons (including exons 46 and 51), as well as a number of method claims comprising the use of such an oligonucleotide.
 
We have been involved in ongoing proceedings with AVI Biopharma Inc. (now Sarepta) regarding EP ’249.
 
Patent Interference Proceedings
 
The United States Patent and Trademark Office has declared three patent interferences involving Prosensa’s examined and allowed composition claims to exon 53 and exon 51 antisense oligonucleotides and Sarepta’s issued composition claims to exon 53 and exon 51 antisense oligonucleotides. A third interference involved Prosensa’s examined and allowed method claims relating to exon 51 antisense oligonucleotides and Sarepta’s issued method claims relating to exon 51 antisense oligonucleotides.  Sarepta’s claims are in patents licensed from the University
 

 
of Western Australia (UWA).  Prosensa’s claims are in patents licensed from LUMC.  Proceedings are still ongoing regarding these interferences.
 
 
The registrant corporation, Prosensa Holding N.V. in liquidatie, has no subsidiaries.
 
 
We lease approximately 20,000 square feet of office and laboratory space at J.H. Oortweg 21 in Leiden, The Netherlands under non-cancellable operating lease agreements with lease terms between 1 and 5 years. The lease is held by BioMarin Nederland BV, a subsidiary of BioMarin Pharmaceutical Inc. This facility serves as the corporate headquarters and central laboratory facility. We believe that our existing facilities are adequate to meet current needs and that suitable additional alternative spaces will be available in the future on commercially reasonable terms.
 
 
As of December 31, 2014 there were no unresolved staff comments.
 
 
You should read the following discussion and analysis of our financial condition and results of operations together with the information under “Selected Financial Data” and our consolidated audited financial statements, including the notes thereto, included in this Annual Report. The following discussion is based on our financial information prepared in accordance with IFRS as issued by the IASB, which might differ in material respects from generally accepted accounting principles in other jurisdictions. The following discussion includes forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including but not limited to those described under “Risk Factors” and elsewhere in this Annual Report.
 
 
Overview
 
We are an innovative biotechnology company engaged in the discovery and development of ribonucleic acid-modulating, or RNA-modulating, therapeutics for the treatment of genetic disorders. Our primary focus is on rare neuromuscular and neurodegenerative disorders with a large unmet medical need, including Duchenne muscular dystrophy, myotonic dystrophy and Huntington’s disease. Our clinical portfolio of RNA-based product candidates is focused on the treatment of DMD. Six of our DMD compounds have been granted orphan drug designation in the United States (US) and the European Union (EU).  Drisapersen, our lead product candidate, has been granted orphan drug designation in the US, EU, Australia and Japan and has been granted breakthrough therapy designation by the FDA for the treatment of DMD.
 
We have financed our operations through offerings of equity securities, upfront, milestone and expense reimbursement payments received from GlaxoSmithKline, or GSK, under our research and development collaboration and license agreement, or the GSK Agreement, as well as funding from patient organizations, governmental bodies and bank loans. From January 1, 2002 until December 31, 2014, we raised gross proceeds of €56.4 million from private placements of equity securities and received £41.5 million (€47.4 million) in payments from GSK and €7.1 million in loans from patient organizations and governmental bodies. In July 2013, we raised proceeds of €64.0 million (before offering expenses) from our initial public offering (“IPO”) of ordinary shares on Nasdaq. On November 26, 2014, we entered into a convertible promissory note with BioMarin for a principal amount of €40.4 million. As of December 31, 2014, we had cash and cash equivalents of €90.7 million. To date, we have not generated any revenues from royalties or product sales. Based on our current plans, we do not expect to generate royalty or product revenues unless and until we obtain marketing approval for, and we commercialize, drisapersen or any of our other product candidates.
 
We have generated losses since we began our drug development operations in 2002. For the years ended December 31, 2014, 2013 and 2012, we incurred net losses of €43.1 million, €16.6 million and €9.9 million respectively. As of December 31, 2014, we had an accumulated deficit of €95.6 million.
 

 
On November 24, 2014 we entered into a purchase agreement with BioMarin. BioMarin launched an initial offering period (tender offer) to purchase all our ordinary shares. On January 15, 2015, BioMarin announced the completion of the previously announced offer by subsidiaries of BioMarin and purchased 93.4% of our shares. BioMarin immediately launched a subsequent offering period that expired on January 29, 2015. As of the expiration of the subsequent offering period, BioMarin paid approximately $659.3 million for approximately 34,970,514 of our shares, representing approximately 96.8% of all of our shares outstanding and for options that vested pursuant to the definitive purchase agreement. On February 12, 2015, we completed the Asset Sale and BioMarin paid an additional $20.8 million to our remaining shareholders that did not tender their shares under the offer. Effective February 12, 2015, Prosensa Holding N.V. is in liquidation under Dutch law. Our operations were mainly carried out through our subsidiary Prosensa Therapeutics B.V., which was transferred to BioMarin in the Asset Sale. Our operations continue to be carried out by Prosensa Therapeutics B.V. as a subsidiary of BioMarin. Effective April 27, 2015, Prosensa Therapeutics B.V. has changed its name to BioMarin Nederland B.V.
 
Collaboration and license agreements
 
GlaxoSmithKline
 
From October 2009 to January 2014, we operated under an exclusive worldwide collaboration with GSK for the development and commercialization of RNA-based therapeutics for DMD, with GSK exclusively licensing worldwide rights to develop and commercialize drisapersen and obtaining an option to exclusively license PRO044 and other specified assets in our DMD portfolio. Under the collaboration agreement, GSK paid us a total of £41.5 million (€47.4 million) in upfront and milestone payments. Under the collaboration agreement, GSK was responsible for all costs of clinical development of drisapersen.
 
In January 2014, we and GSK mutually terminated the collaboration pursuant to a termination agreement, which terminates all intellectual property license grants as well as any rights arising under the collaboration agreement (other than rights to payments that accrued prior to termination of the collaboration). In addition, the termination agreement required GSK to transfer to us certain data and know how, inventory, regulatory filings, clinical trial sponsorships, clinical study reports and material agreements relating to the development of our products. We and GSK each agreed to indemnify the other party with respect to certain acts and omissions.
 
Leiden University Medical Center
 
We have entered into an exclusive worldwide license agreement with Leiden University Medical Center, or LUMC, for the rights to apply LUMC’s proprietary RNA modulation exon-skipping technology to develop treatments for DMD, other neuromuscular disorders and indications outside the field of neuromuscular disorders. We are obligated to make milestone payments upon the occurrence of events with respect to each subfield in which we pursue a drug indication using the LUMC patent rights, including commencing the first toxicity study, successfully completing the first Phase I study, filing for regulatory approval and satisfying certain sales thresholds.
 
To date, we have paid LUMC €3.6 million in milestone payments under the agreement. The agreement with LUMC has been transferred to BioMarin as part of the Asset Sale.
 
Critical accounting policies and significant judgments and estimates
 
Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which we have prepared in accordance with IFRS as issued by the IASB. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenues and expenses during the reporting periods. Actual results may differ from these estimates under different assumptions or conditions.
 
While our significant accounting policies are more fully described in the notes to our consolidated financial statements appearing elsewhere in this Annual Report, we believe that the following accounting policies are the most critical to aid you in fully understanding and evaluating our financial condition and results of operations.
 

 
Other loans & Finance costs
 
Certain loans from patient organizations have no fixed redemption schemes and repayment is due when certain pre-determined milestones are met. A change in the estimate in the redemption date impacts the carrying value of the loans. The effect of a one year delay of the redemption dates of these loans would have decreased our borrowing balance by €1.0 million as of December 31, 2014. A selected number of such loans were either repaid before the Asset Sale or were assigned to BioMarin Falcons B.V. in the Asset Sale.
 
Intangible assets
 
As of December 31, 2014, we recorded patents and licenses with a net book value of €0.4 million. As of December 31, 2014, there were no changes to management assumptions used to determine the patent and licenses’ recoverable amount, which exceeds the carrying value of €0.4 million.
 
Deferred revenue & License income
 
Upfront license fee payments received under the research and collaboration agreement with GSK were initially deferred and recognized based on the percentage of completion method, which required us to estimate the work performed to date as a proportion of the total work expected to be performed. As a result of the termination of the research and collaboration agreement, we were released from any performance obligations and recorded €14.7 million license revenue in the first quarter of 2014.
 
Revenue recognition and cost of license revenue
 
In October 2009 the Company signed a Research & Development and Collaboration & License agreement with GSK. Upon signing of the agreement the Company received €17.2 million (£ 16.0 million) as a non-refundable upfront payment. Until the termination of the agreement effective on January 12, 2014, the Company had continuing performance obligations and revenues related to the license fee payments were deferred and the related revenues were recognized in the period of the expected performance. The Company made the assumption that the expected performance occurred on a straight line basis over the 5 year period the Company was deemed obliged to provide research and development services regarding certain pre-defined programs in the agreement.
 
Other upfront license fee payments are deferred and revenue is recognized based on the percentage of completion method. Use of the percentage of completion method requires the Company to estimate the work performed to date as a proportion of the total work to be performed.
 
The related cost of license revenue is based on the determination of net license revenue as defined in our license agreements after deducting allocable expenses and is subject to a certain amount of judgment.
 
Other income
 
We are part of two pan-European consortia, each consortium has been awarded a Framework Programme 7 (“FP7”) research grant of €6 million from the European Commission to support respectively ongoing clinical study PRO045 and the development of imaging biomarkers for Duchenne muscular dystrophy (DMD). We have also received government research subsidies. Grant proceeds are deferred and other income is recognized based on the percentage of completion method.
 
To encourage research and development we obtained certain loans that generally bear interest at a rate below the market interest rate, considered by the company to be 12% over the last five years. The difference between fair value of the loans and the notional amount of the loans at inception is treated as a donation received for certain research and recognized in Other income over the periods during which expenses are incurred. As of December 31, 2014, €0.1 million (2013: €0.1 million) is deferred and will be recognized in Other income over the periods when expenses are incurred.
 
Research and development expense
 
Research expenses are recognized as expenses when incurred. Costs incurred on development projects are recognized as intangible assets as of the date as of which it can be established that it is probable that future economic benefits attributable to the asset will flow to us considering its technological and commercial feasibility. This is
 

 
generally the case when regulatory approval for commercialization is achieved and costs can be measured reliably. Given the current stage of the development of our products, no development expenditures have yet been capitalized. Intellectual property-related costs for patents are part of the expenditure for the research and development projects. Therefore, registration costs for patents are expensed when incurred as long as the research and development project concerned does not meet the criteria for capitalization.
 
As part of the process of preparing our financial statements we are required to estimate our accrued expenses. This process involves reviewing quotations and contracts, identifying services that have been performed on our behalf, estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. The significant estimates in our accrued research and development expenses are related to fees paid to clinical research organizations, or CROs, in connection with research and development activities for which we have not yet been invoiced. We base our expenses related to CROs on our estimates of the services received and efforts expended pursuant to quotes and contracts with CROs that conduct research and development on our behalf.
 
The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the research and development expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepayment expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting amounts that are too high or too low in any particular period.
 
Share-based compensation
 
Employee stock options
 
We have adopted share-based compensation plans, pursuant to which certain participants are granted the right to acquire ordinary shares of the Company (option shares). The share-based compensation plans are equity-settled. Upon the exercise or award or vesting of a non-cash-settled award under the plans, we issue ordinary shares.
 
Following the completion of the tender offer of BioMarin on January 15, 2015, all share-based awards fully vested. At December 31, 2014, we revised our estimate of the number of equity instruments that were expected to vest and accelerated the vesting period in light of the transaction with BioMarin. The accelerated vesting of the awards resulted in a share-based compensation expense of €3.5 million for the year ended December 31, 2014.
 
Prior to our IPO, participants were not granted the right to acquire ordinary shares but (non-voting) depository receipts (“Depositary Receipts”) in respect of our ordinary shares. Upon the exercise or award or vesting of a non-cash-settled award under the plans, ordinary shares were issued to a Dutch foundation called Stichting Administratiekantoor Prosensa Holding (the “Foundation”), whose purpose was to facilitate administration of options and pool the voting interests of the underlying shares. The Foundation thereupon granted a Depository Receipt for each issued ordinary share to the person entitled to such ordinary share under an award. Legal title to the shares issued under the share-based compensation plan was held by the Foundation, and the voting rights attached to the shares were exercised by the Foundation at its own discretion. After our IPO the Foundation transferred the shares to the holders of Depository Receipts. The Foundation was dissolved during 2014.

Options are generally conditional on the employee completing a four year period of service (the vesting conditions). Each such option award vests based on the following schedule: (a) 25% on the first anniversary of the date of the grant, provided that on that date the relevant participant is still employed by us, and (b) the remaining 75% in 36 equal monthly installments over a three year period following the first anniversary of the date of grant subject to continued employment of the relevant participant. We decided to accelerate the vesting of the options as a result of the change of control.
 

 
The following table summarizes by grant date the number of options granted between January 1, 2012 and December 31, 2014:

On December 5, 2012, we granted to the members of the Management Board 1.0 million options that vest only upon a liquidity event such as a change of control of the Company or an IPO, subject to the continued employment of the member of the Management Board. Following our IPO, the maximum number of options eligible to vest was automatically reduced from 1.0 million to 800,000. In order for any options to become subject to vesting the sustained closing market price for the ordinary shares during any 20 consecutive trading days outside a lock-up or blackout period must exceed a threshold share price. The number of options subject to vesting increases between the threshold share price and the share price entitling the participant to exercise the maximum number of options. Upon each subsequent achievement of a sustained, higher closing market price or level of proceeds from a liquidity event, an additional number of options will become subject to vesting. Each option grant subject to vesting following our IPO will vest and become exercisable based on the following schedule: 25% of the options subject to vesting will vest the day immediately following attainment of such pricing levels (the initial vesting date), and an additional 2.083% will vest at the end of each successive one month period following the initial vesting date, subject to the continued employment of the relevant member of the management board.
 
Unless forfeited or exercised on an earlier date, the options expire 10 years after the grant date.
 
Prior to our initial public offering, we were a private company and lacked company-specific historical and implied volatility information and therefore estimated the expected volatility based on the historical volatility of certain publicly traded peer companies.  Volatility was set at 100% for options granted in 2014 and after our IPO on July 3, 2013, at 95% for options granted before July 3, 2013 and at 80% for options granted in 2012.

Income taxes
 
We are subject to income taxes in the Netherlands and in the United States. Significant judgment is required in determining the use of net operating loss carry forwards and taxation of upfront and milestone payments for income tax purposes. There are many transactions and calculations for which the ultimate tax determination is uncertain. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the current and deferred income tax assets and liabilities in the period in which such determination is made.
 
No tax charge or income was recognized during the reporting periods since we are in a loss-making position and have a history of losses. We have tax loss carry-forwards of €112.4 million as of December 31, 2014. As a result of the Dutch income tax law, tax loss carry-forwards are subject to a time limitation of nine years. Deferred income tax assets are recognized for tax losses and other temporary differences to the extent that the realization of the related tax benefit through future taxable profits is probable. We recognize deferred tax assets arising from unused tax losses or tax credits only to the extent the relevant fiscal unity has sufficient taxable temporary differences or if there is convincing other evidence that sufficient taxable profit will be available against which the unused tax losses or unused tax credits can be utilized by the fiscal unity. Our judgment is that sufficient convincing other evidence is not available and a deferred tax asset is therefore not recognized.
 
In order to promote innovative technology development activities and investments in new technologies, a corporate income tax incentive has been introduced in Dutch tax law called the Innovation Box. For the qualifying profits, we effectively owe only 5% income tax, instead of the general tax rate of 25% which results in an estimated effective tax rate of 10%. The agreement with the tax authorities is currently signed for the years 2011 to 2015 but is expected to be extended.
 
Borrowings
 
From January 1, 2002 through December 31, 2014, we received the following loans from patient organizations and governmental bodies: €3,390,000 from Association Française contre les Myopathies (AFM), €840,000 from Agentschap NL, €500,000 from the Stichting Duchenne Parents Project, €387,000 from Charley’s Fund, €502,000 from Everest International Pte Ltd, €750,000 from Cure Duchenne, €163,000 from Aktion Benni & Co., €500,000 from Duchenne Children’s Trust and €65,000 from Villa Joep. These arrangements are generally in the form of below-market interest rate loans that become due upon the meeting of certain milestones in product development, generally a minimum threshold of commercialization success or successful completion of certain clinical trials. Significant judgment is required in determining when these pre-determined milestones are met and may vary over time, implying a change in the value of the loans.
 
As of December 31, 2014, we had outstanding notes convertible into our shares held by an affiliate of Cure Duchenne in a principal amount of €500 thousand and by BioMarin Falcons B.V. in a principal amount of €40.4 million. The fair value of the conversion option of those notes has been determined using option pricing models with key inputs classified as Level 3 in the fair value hierarchy. We have made assumptions on relevant factors such as the investor's conversion strategy or the probability of the notes being converted. As of December 31, 2014, none of the notes had been converted.
 
As a result of the Acquisition, a selected number of borrowings have been repaid either by us or by BioMarin in 2015. The total borrowings repaid as of the date of this Annual Report amounted to €2.7 million, which approximates their carrying value at December 31, 2014, plus the accrued interest until payment in 2015.
 
The repaid loans include €840,000 thousand from Agentschap NL. We had pledged part of our material and immaterial fixed assets that directly related to the project funded by this loan and this pledge was fully released following the repayment.
 
Recent accounting pronouncements
 
There are no IFRS standards as issued by the IASB or interpretations issued by the IFRS interpretations committee (e.g. Amendment to IAS 36 Impairment of Assets, Amendment IAS 39 Financial Instruments and IFRIC 21 Levies) that are effective for the first time for the financial year beginning on or after January 1, 2014 that had a material impact on our financial position.
 

 
JOBS Act exemptions
 
On April 5, 2012, the JOBS Act was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for an “emerging growth company.” As an emerging growth company, we are electing to take advantage of the following exemptions:
 
 
·
not providing an auditor attestation report on our system of internal controls over financial reporting;
 
 
·
not providing all of the compensation disclosure that may be required of non-emerging growth public companies under the U.S. Dodd-Frank Wall Street Reform and Consumer Protection Act;
 
 
·
not disclosing certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the Chief Executive Officer’s compensation to median employee compensation;
 
 
·
not complying with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis).
 
The JOBS Act permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We are choosing to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards as required when they are adopted. This decision to opt out of the extended transition period under the JOBS Act is irrevocable.
 
These exemptions will apply for a period of five years following the completion of our IPO (2018) or until we no longer meet the requirements of being an “emerging growth company,” whichever is earlier. We would cease to be an emerging growth company if we have more than $1.0 billion in annual revenue, have more than $700 million in market value of our ordinary shares held by non-affiliates or issue more than $1.0 billion of non-convertible debt over a three- year period.
 
Financial operations overview
 
Total revenue
 
From October 2009 to January 2014, we operated under an exclusive worldwide collaboration with GSK for the development and commercialization of RNA-based therapeutics for DMD, with GSK exclusively licensing worldwide rights to develop and commercialize drisapersen and obtaining an option to exclusively license PRO044 and other specified assets in the Company’s DMD portfolio. Under the research and collaboration agreement, GSK paid us a total of £41.5 million (€47.4 million) in upfront and milestone payments. Under the research and collaboration agreement, GSK was responsible for all costs of clinical development of drisapersen.
 
On January 12, 2014, the research and collaboration agreement was mutually terminated pursuant to a termination agreement, which terminated all intellectual property license grants as well as any rights arising under the research and collaboration agreement (other than rights to payments that accrued prior to termination of the collaboration). In addition, the termination agreement required GSK to transfer to us certain data and know-how, inventory, regulatory filings, clinical trial sponsorships, clinical study reports and material agreements relating to the development of our products.
 
Until the termination agreement with GSK, our revenues consisted principally of license revenue and collaboration revenue. For 2014, 2013 and 2012, all of our license revenue and collaboration revenue was generated under the GSK Agreement.
 
 
·
License revenue. License revenue included upfront payments and milestone payments. In 2009, we received a £16.0 million (€17.2 million) nonrefundable upfront payment from GSK in connection with our entry into the GSK research and collaboration agreement. The agreement to terminate the research and collaboration agreement released us from any performance obligations under the upfront payments already received from GSK. As a result, we recognized €14.5 million deferred license revenue in 2014. The release from any performance obligations also resulted in recognition of €0.2 million revenue related to other services delivered under the research and collaboration agreement with GSK. Until December 31, 2013 we
 

 
recognized this payment ratably over five years, and in each year we recognized revenue of €3.4 million. In addition, we recognized revenue of €2.2 million (2012: €2.3 million) related to unconditional milestone payments for research under the GSK Agreement.
 
 
·
Collaboration revenue. Collaboration revenue is revenue from contracts, typically for research and development activities under the GSK research and collaboration agreement. In 2014, collaboration revenue was minimal due to the termination of the research and collaboration agreement. In 2013 we recognized €3.3 million (2012: €2.1 million) of collaboration revenues. In each period the revenues were mainly for services provided under the GSK Agreement related to the research and development of drisapersen and PRO044.
 
Our financial results have varied substantially and are expected to continue to vary from period to period. Under our historical collaboration with GSK, GSK reimbursed us for the cost of the clinical trials of drisapersen as well as a substantial portion of the costs of the clinical trials of PRO044 and our natural history study of DMD, and paid us milestone payments upon successful development. Following the mutual termination of the collaboration in January 2014, we will bear the full cost of any additional clinical trials of drisapersen and our other DMD product candidates and will receive no future payments under the collaboration other than those accrued on the date of the termination. We are in liquidation, and our assets have been transferred to BioMarin as part of the Asset Sale.  Consequently, we do not expect to have future revenues.
 
Other income
 
Other income for the year ended December 31, 2014 amounts to €0.7 million (2013: €0.6 million; 2012: €0.2 million). We are part of two pan-European consortia, each of which has been awarded Framework Programme 7 (FP7) research grants from the European Commission, and we have also received governmental research grants. Grant proceeds are deferred, and other income is recognized based on the percentage of completion method for an amount of €0.7 million in the year ended December 31, 2014 (2013: €0.5 million, 2012: nil).
 
To encourage research and development we obtained certain loans that generally bear interest at a rate below the market interest rate, considered by the company to be 12% over the last five years. The difference between the fair value of the loans and the notional amount of the loans at inception is treated as a donation received for certain research performed by the company. As of December 31, 2014 an amount of €0.1 million (2013: €0.1 million, 2012: nil) is deferred and will be recognized in Other income over the periods during which expenses are incurred.
 
Cost of license revenue
 
We are obligated to make payments to LUMC upon the achievement of specified milestones, if any of our product candidates become successfully commercialized and if we generate certain revenues from sublicensing to a third party our rights under the agreement, as we historically have to GSK. For the years ended December 31, 2014, 2013 and 2012, we did not incur any costs associated with license revenue as we did not generate any applicable revenue.
 
Research and development expense
 
Research and development expense consists principally of:

 
·
salaries for research and development staff and related expenses, including social security costs;
 
·
costs for production of (pre)clinical compounds and drug substances by contract manufacturers;
 
·
fees and other costs paid to contract research organizations in connection with additional (pre)clinical testing and the performance of clinical trials;
 
·
costs of related facilities, materials and equipment;
 
·
costs associated with obtaining and maintaining patents and other intellectual property; and
 
·
amortization and depreciation of tangible and intangible fixed assets used to develop our product candidates.
 
Our future research and development expense may vary substantially from the periods presented in this report. Under our historical collaboration agreement with GSK, GSK reimbursed us or paid directly for the cost of
 

 
the clinical trials of drisapersen, as well as a substantial portion of the costs of the clinical trials of PRO044 and the natural history study and paid us milestone payments upon successful compound development. As a subsidiary of BioMarin, we expect that BioMarin will make all future decisions regarding funding requirements and expenditures for our product candidates going forward.
 
The successful development of our product candidates is highly uncertain. At this time we cannot reasonably estimate the nature, timing and estimated costs of the efforts that will be necessary to complete the development of, or the period, if any, in which material net cash inflows may commence from, any of our product candidates. This is due to numerous risks and uncertainties associated with developing drugs, including the uncertainty of:
 
 
·
the scope, rate of progress and expense of our research and development activities;
 
·
clinical trial and early-stage results;
 
·
the terms and timing of regulatory approvals;
 
·
the expense of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights; and
 
·
the ability to market, commercialize and achieve market acceptance for drisapersen or any other product candidate that we may develop in the future.
 
A change in the outcome of any of these variables with respect to the development of drisapersen or any other product candidate that we may develop could mean a significant change in the costs and timing associated with the development of drisapersen or such product candidate.
 
General and administrative expense
 
Our general and administrative expense consists principally of:
 
 
·
salaries for employees other than research and development staff, as well as expenses related to share-based compensation awards granted to all of our employees;
 
·
professional fees for auditors and other consulting expenses not related to research and development activities;
 
·
professional fees for lawyers not related to the protection and maintenance of our intellectual property;
 
·
cost of facilities, communication and office expenses;
 
·
IT expenses; and
 
·
amortization and depreciation of tangible and intangible fixed assets not related to research and development activities.
 
Finance income
 
Our cash and cash equivalents have been deposited primarily in saving and deposit accounts with original maturities of 3 months or less. Saving and deposit accounts generate a small amount of interest income.

Total Revenue
 
License revenue increased €9.1 million in the year ended December 31, 2014, compared to the corresponding period in 2013 due to the termination of the research and collaboration agreement with GSK and the related release of deferred revenue balances.
 
Collaboration revenue is revenue from contracts, typically for research and development activities related to the services provided under the research and collaboration agreement. The decrease in collaboration revenue to €0.1 million in the year ended December 31, 2014 from €3.3 million in the year ended December 31, 2013 is due to the termination of the research and collaboration agreement. Pursuant to the termination of our collaboration with GSK, we do not expect any future license or collaboration revenue under the collaboration. Any new collaboration arrangements we may enter into and the terms we are able to negotiate may impact our revenue for future periods. We therefore believe that period to period comparisons should not be relied upon as indicative of our future revenues.
 
Other income
 
Other income in the year ended December 31, 2014, amounts to €0.7 million (2013: €0.6 million). We are part of two pan-European consortia, each of which has been awarded Framework Programme 7 (“FP7”) research grants from the European Commission, and we have also received governmental research grants. Grant proceeds are deferred, and other income is recognized based on the percentage of completion method.
 
We obtained certain loans made to support research and development that generally bear interest at a rate below the market interest rate, considered by us to be 12% over the last five years. The difference between fair value and the notional amount at inception is treated as a grant received for certain research performed by us and is deferred and recognized in other income over the periods during which research and development expenses are incurred. We recognized other income related to these loans for an amount of €0.01 million in the year ended December 31, 2014 (2013: €0.01 million).

Research and development expense increased from €18.5 million in 2013 to €32.0 million in 2014. Our research and development expense is highly dependent on the development phases of our projects and therefore fluctuates highly from period to period. After termination of the research and collaboration agreement with GSK in January 2014, GSK did not reimburse us or pay directly for the cost of the clinical trials of drisapersen, as well as a substantial portion of the costs of the clinical trials of PRO044 and the Natural History study.
 
The variances in expense between 2014 and 2013 are mainly due to the following projects:
 
 
·
DMD projects. The DMD project expenses mainly consist of salaries, costs for production of the compounds, costs paid to contract research organizations and costs relating to preparing our regulatory filings for drisapersen. During 2014, we mostly incurred expenses related to the expansion of our development and regulatory capabilities, other expenses for drisapersen (€11.1 million), costs for progressing clinical Phase I/II studies of both PRO045 and PRO053 (€6.1 million) and preparation for the PRO044 extension study planned to start in 2015 (€1.4 million). In 2014, we also incurred research and development expenses for our other projects supporting the DMD program, such as the Natural History study and PROSPECT.
 
 
·
Non-DMD projects. The expenses for our non-DMD projects DM1 and HD mainly consist of outsourced studies.
 
 
·
Infrastructure costs: we incur a significant amount of costs associated with our research and development that are less dependent on individual ongoing programs and they are therefore not allocated to specific projects, of which intellectual property expenses increased in 2014 (€2.0 million).
 
General and Administrative Expense
 
General and administrative expense increased to €25.9 million from €7.7 million in the years ended December 31, 2014 and 2013, respectively. The increase is primarily due to share-based compensation expense and costs related to the acquisition by BioMarin in the year ended December 31, 2014, offset by expenses related to our initial public offering (IPO) in the same period in 2013.
 
Other (Losses)/Gains-net
 
Other (losses)/gains mainly related to currency effects on outstanding receivables in the years ended December 31, 2014 and 2013.
 
Finance Income
 
Finance income increased €0.2 million in the year ended December 31, 2014, compared to the same period in 2013 mainly due to currency effects in our cash and cash equivalents and the fair value adjustments of financial liabilities.
 
Finance Cost
 

 
Finance cost increased €0.8 million in the year ended December 31, 2014, compared to 2013. Higher finance costs were mainly due to higher outstanding borrowing balances in 2014.

License revenue decreased to €5.6 million in 2013 from €5.7 million in 2012. In 2009, we received a £16.0 million (€17.2 million) nonrefundable upfront payment from GSK in connection with our entry into the GSK Agreement. We are recognizing this payment ratably over five years, and in each of 2013 and 2012, we recognized revenue of €3.4 million related to this agreement. In addition, we recognized revenue of €2.2 million and €2.3 million related to unconditional milestone payments received under the GSK Agreement in the years 2013 and 2012, respectively.
 
Collaboration revenue
 
Collaboration revenue increased to €3.3 million in 2013 from €2.1 million in 2012. This revenue was generated from services provided under the GSK Agreement and increased due to additional research and development activities on drisapersen and PRO044.
 
Other income
 
Other income increased to €0.6 million in 2013 from €0.2 million in 2012. During 2013 we were awarded research grants from the European Commission as well as other research subsidies. Grant proceeds are deferred and other income is recognized based on the percentage of completion method which totaled €0.5 million during the year ended December 31, 2013.
 
To encourage research and development we obtained certain loans that generally bear interest at a rate below the market interest rate, considered by the company to be 12% over the last five years. The difference between fair value of the loans and the notional amount of the loans at inception is treated as a donation received for certain research performed by the company and totaled €0.1 million for the year ended December 31, 2013 (2012: €0.2 million). As of December 31, 2013 €0.1 million is deferred and will be recognized in Other income over the periods during which expenses are incurred.

Research and development expense increased to €18.5 million in 2013 from €14.4 million in 2012. Our research and development expense is highly dependent on the development phases of our projects and therefore fluctuates highly from year to year. The variances in expense between 2013 and 2012 are mainly due to the following projects:
 
 
·
DMD projects. While we incurred expenses for preclinical safety studies for PRO045 and PRO053 in 2012, our research and development expenses in 2013 mainly related to the ongoing phase I/II study of PRO045 and PRO053. In 2013 we also incurred expenses for the 3-months preclinical safety studies for PRO052, the Natural History and PROSPECT programs.
 
 
·
Non-DMD projects. The expenses for our non-DMD projects DM1 and HD mainly consist of outsourced in vivo proof-of-concept studies and the corresponding manufacturing of the preclinical compounds in both years.
 
 
·
Infrastructure costs. We incur a significant amount of costs associated with our research and development that are non-project specific, including intellectual property-related expenses, depreciation expenses and facility costs. Because these are less dependent on individual ongoing programs, they are not allocated to specific projects. These costs were higher in 2013 versus 2012 mainly due to intellectual property expense.
 
General and administrative expense
 
General and administrative expense increased substantially to €7.7 million in 2013 from €4.0 million in 2012. The increase was primarily related to costs associated with our IPO in the amount of €1.4 million, additional costs incurred for operating as a public company and non-cash share-based compensation charges.
 
Other gains - net
 
Other gains mainly related to foreign currency results on outstanding receivable balances in 2013 and 2012.
 
Finance income
 
Finance income decreased to €0.6 million in 2013 from €0.8 million in 2012 due to lower interest rates on cash deposits in 2013 offset by higher cash balances in 2013. Finance income in these years consisted primarily of interest income recognized on short-term deposits.
 
Finance cost
 
Finance cost increased to €0.7 million in 2013 from €0.3 million in 2012. Higher finance costs are mainly due to new borrowings from patient organizations and governmental bodies totaling €2.6 million received in December 2012 and during 2013.
 
 
To date, we have financed our operations through private placements of our equity securities and our IPO, upfront, milestone and expense reimbursement payments received from GSK, as well as funding from patient organizations, governmental bodies and bank loans and a promissory note with BioMarin.
 

 
We are exposed to changes in economic environment such as changes in interest rates. At December 31, 2014 if our interest rates on borrowings had been 0.1% higher/lower with all other variables held constant, post-tax results for the year would have been €49 thousand (2013: €8 thousand 2012: €6 thousand) lower/higher as a result of changes in the fair value of the borrowings.
 
Cash flows
 
Comparison of the year ended December 31, 2014 and 2013
 
Our cash and cash equivalents as of December 31, 2014 were €90.7 million. The table below summarizes our statement of cash flows for the years ended December 31, 2013 and 2014:

Cash and cash equivalents at the end of the period

The net cash used in operating activities of €31.4 million in the year ended December 31, 2014, increased from net cash used in operating activities of €22.0 million in 2013 mainly due to a higher operating loss excluding license income and share based compensation expenses (both non-cash items) for a net amount of €32.5 million and increased cash generated from changes in working capital for an amount of €22.3 million. For an explanation of the operating loss, please see “Results of Operations”.
 
The net cash used in investing activities increased to €1.0 million in the year ended December 31, 2014 from €0.4 million in 2013 due to higher investments in fixed assets offset by the decrease in restricted cash.
 
The decrease in net cash generated from financing activities to net cash generated of €40.8 million in the year ended December 31, 2014, from net cash generated of €63.9 million in 2013 is due to a decrease in net proceeds from issuance of share capital of €62.8 million in the year ended December 31, 2014, compared to the same period in 2013 which included the proceeds from our IPO, an increase in received borrowings of €39.9 million offset with higher repayment of borrowings of €0.3 million in the year ended December 31, 2014, and €0.2 million lower amount of finance lease redemptions in the year ended December 31, 2014, compared to the same period in 2013.
 
Comparison of the year ended December 31, 2013 and 2012
 
Our cash and cash equivalents as of December 31, 2013 were €82.2 million. The table below summarizes our statement of cash flows for the years ended December 31, 2013 and 2012:

The net cash used in operating activities of €3.7 million in the year ended December 31, 2012 increased to net cash used in operating activities of €22.0 million in 2013 due to higher collection of milestone payments in 2012 and a higher operating loss of €6.2 million in 2013. For an explanation of the higher operating loss of €6.2 million, please see “Item 5. Operating and Financial Review and Prospects—A. Operating Results”.
 
The net cash used in investing activities increased to €0.4 million in the year ended December 31, 2013 from €0.3 million in the year ended December 31, 2012, due to higher investments in tangible fixed assets.
 
The increase in net cash generated from financing activities to €63.9 million in the year ended December 31, 2013 from €26.0 million in the year ended December 31, 2012, is primarily attributable to the net proceeds of the share issuance in 2012 for an amount of €22.7 million compared to the net proceeds of €63.2 million received from our IPO in July 2013 offset by a decrease of €2.8 million in borrowings received.
 
Funding requirements
 
Our funding requirements may vary substantially from the periods presented in this report. Under our historical collaboration with GSK, GSK reimbursed us for the cost of the clinical trials of drisapersen as well as a substantial portion of the costs of the clinical trials of PRO044 and our natural history study of DMD, and paid us milestone payments upon successful development. As a subsidiary of BioMarin, we expect that BioMarin will make all future decisions regarding funding requirements and expenditures for our product candidates going forward.

For the year ended December 31, 2013, we invested €0.7 million in tangible and intangible fixed assets, including €57 thousand in tangible assets not paid for at December 31, 2013. We also lease various laboratory and office equipment under non-cancellable finance lease agreements. In 2014, 2013 and 2012 we recorded non-cash increases to our property and equipment related to assets acquired under finance leases of nil, €66 thousand and €52 thousand respectively.

(1)
Debt obligations consist of loans from patient organizations and governmental bodies and our loan with BioMarin Falcons B.V. (the BioMarin loan). In February 2015, €40.9 million of our debt obligations due in less than one year was transferred to BioMarin Falcons B.V., the issuer of the BioMarin loan. Most loans from patient organizations and governmental bodies have no fixed repayment scheme, but repayment (including incurred interest) is due when certain pre-determined milestones are met. See “Item 5. Operating and Financial Review and Prospects—A. Operating results—Critical accounting policies and significant judgments and estimates—Borrowings.” Because we cannot predict what portion will be due in less than five years, we have classified these repayments in the category “More than 5 years.”
 
(2)
As disclosed in our consolidated financial statements, certain loan agreements include additional payments due after we reach a predefined commercial sales milestone. These conditional payments total a maximum of approximately €5.0 million if all such commercial sales milestones are exceeded. These amounts do not include conditional future interest payable.
 
(3)
Operating lease obligations consist of payments pursuant to lease agreements for office and laboratory facilities, which terms will expire before the third quarter of 2016, as well as lease agreements for office furniture, which will expire in 2017.
 
(4)
R&D purchase commitments mainly consist of clinical supply manufacturing contracts. We enter into contracts in the normal course of business with CROs for clinical trials and with vendors for safety and research studies, research supplies and other services and products for operating purposes. These contracts generally provide for termination on notice, and therefore are cancelable contracts and not included in the table of contractual obligations and commitments.
 
(5)
Other non-current liabilities includes accrued professional fees related to the BioMarin Acquisition.
 
(6)
In 2014 we repaid all our remaining finance lease obligations.
 
 
See “Forward Looking Statements.”
 
 
 
We have a two-tier board structure consisting of our supervisory board (raad van commissarissen) and a separate management board (raad van bestuur).
 
Our supervisory board supervises the policies of the management board and the general course of the affairs of our business. The supervisory board gives advice to the management board and is guided by the interests of the business when performing its duties. The management board is in charge of managing us under the supervision of the supervisory board. The management board provides the supervisory board with such necessary information as the supervisory board requires to perform its duties.
 
On January 13, 2015, we held an extraordinary general meeting of shareholders whereat we approved certain agenda items to become effective upon the Closing, including the resignation of certain managing and supervisory directors and the appointment of new managing and supervisory directors designated by BioMarin.  Thus, as a result of the Closing, the resignation of all pre-Closing managing directors became effective, with the exception of Giles Campion who did not resign.  Also effective upon the Closing were the resignations of all pre-Closing supervisory directors, with the exception of David Mott who did not resign.  The appointments of Scott Clarke and Richard Holslag to the management board, and Hans Schikan, Henry Fuchs, Robert Baffi and G. Eric Davis to the supervisory board, became effective upon the Closing, and the reappointments of David Mott to the supervisory board and Giles Campion to the management board became effective upon the Closing as well.
 
The following table presents our supervisory directors. David Mott is the chairman of our supervisory board. The term of each of our supervisory directors will terminate on the earliest of (i) such time as BioMarin owns 100% of our outstanding shares (ii) the cessation of the Company following its dissolution and liquidation or (iii) November 23, 2015.

The following is a brief summary of the business experience of our supervisory directors. Unless otherwise indicated, the current business address for each of our supervisory directors is J.H. Oortweg 21, 2333 CH Leiden, the Netherlands.
 
Robert Baffi has served on our supervisory board since January 2015. Dr. Baffi joined BioMarin in May 2000 and currently serves at BioMarin as Executive Vice President of Technical Operations responsible for overseeing the company’s manufacturing, process development, quality, GMP and GLP compliance and analytical chemistry departments. From 1986 to 2000, Dr. Baffi served in a number of increasingly responsible positions at Genentech, primarily in the functional area of quality control. Prior to Genentech, Dr. Baffi worked for Cooper BioMedical as a Research Scientist and at Becton Dickinson Research Center as a Post-Doctoral Fellow. Dr. Baffi has contributed to more than 20 regulatory submissions for product approval in the United States and Europe and to more than 50 regulatory submissions for investigational new drug testing. Dr. Baffi received a Ph.D, M.Phil and a B.S. in biochemistry from the City University of New York and an M.B.A. from Regis University. We believe Dr. Baffi is qualified to serve on the supervisory board because of his experience in the biopharmaceutical industry, his current role as executive vice president technical operations of BioMarin, as well as his service on other boards of directors.
 
G. Eric Davis has served on our supervisory board since January 2015. Mr. Davis joined BioMarin in March 2004, and currently serves at BioMarin as Senior Vice President, General Counsel and Secretary. From 2000 to 2004, Mr. Davis worked in the San Francisco office of Paul Hastings Janofsky & Walker LLP, where he served on the firm's national securities practice committee. Mr. Davis has represented public and private companies and venture capital and investment banking firms in a wide range of corporate and securities matters, mergers and acquisitions, strategic alliance matters, and intellectual property-related business transactions. His experience involves a variety of industries, including biotechnology and life sciences. Mr. Davis received a B.A. in political economy from the University of California, Berkeley, and a J.D. from the University of San Francisco School of Law. We believe Mr. Davis is qualified to serve on the supervisory board because of his experience as an attorney, his role as general counsel and secretary of BioMarin, as well as his service on other boards of directors.
 
Henry Fuchs has served on our supervisory board since January 2015. Dr. Henry Fuchs joined BioMarin in 2009 and currently serves at BioMarin as Executive Vice President and Chief Medical Officer. Previously he served as Executive Vice President and Chief Medical Officer of Onyx Pharmaceuticals. He served as a Director of Ardea Biosciences beginning in November 2001 and as its Chief Executive Officer from January 2003 until June 2005. Dr. Fuchs first joined Ardea as Vice President, Clinical Affairs in October 1996 and was appointed President and Chief Operating Officer in November 2001. From 1987 to 1996, Dr. Fuchs held various positions at Genentech where, among other responsibilities, he led the clinical program that resulted in the approval of Genentech’s Pulmozyme. Dr. Fuchs was also responsible for the Phase III development program that led to the approval of Herceptin to treat metastatic breast cancer. Dr. Fuchs received an M.D. degree from George Washington University and a B.A. degree in biochemical sciences from Harvard University. We believe Dr. Fuchs is qualified to serve on the supervisory board because of his experience in the biopharmaceutical industry, his current role as chief medical officer of BioMarin, and his experience on the board of directors of other public biopharmaceutical companies.
 
David Mott has served on our supervisory board since 2012 and as its chairman since 2013. Mr. Mott has served as a general partner of New Enterprise Associates, an investment firm focused on venture capital and growth equity investments, since September 2008, where he leads the healthcare investing practice.

director or lead director of Edimer and Epizyme, Inc. Mr. Mott received a Bachelor of Arts degree from Dartmouth College. Mr. Mott was nominated to serve on our board by New Enterprise Associates, one of our shareholders.  We believe that Mr. Mott is qualified to serve on the supervisory board because of his experience as a venture capital investor, his experience in the pharmaceutical industry and his service on the boards of directors of other biopharmaceutical companies.

He is also past Chairman of Nefarma, the Dutch Association of Research Based Pharmaceutical Industry and served as an Executive Board Member of the Dutch Top Institute Pharma. Mr. Schikan holds a Pharm.D. degree from the University of Utrecht, the Netherlands. We believe that Mr. Schikan is qualified to serve on the supervisory board because of his experience in the biopharmaceutical industry, his previous role as chief executive officer of the Company, his extensive knowledge of the Company and its business and his experience on the board of directors of another public biopharmaceutical company, as well as on the boards of various other organizations in the biopharmaceutical industry.
 
Following the completion of the Asset Sale, Stichting Prosensa, the liquidation entity, took over management of the Company on February 12, 2015 to commence and effectuate the liquidation process in accordance with Dutch law. The following table lists the members of the current management board of Stichting Prosensa:

Employment agreements of managing directors
 
Prior to the Acquisition, we had employment agreements with each of our managing directors. The employment agreements contained a termination notice period of three months for the managing director and six months for us. All of the employment agreements provided that the managing director may be terminated in the event of an urgent reason (dringende reden) at any time, without advance notice. Each employment agreement provided for severance pay upon (i) a termination of the managing director’s employment without cause, (ii) the resignation of the
 

 
managing director within 12 months following a change in control event or (iii) or at the end of their term of appointment, unless the managing director is re-appointed. For termination without cause, this severance pay was calculated based on that managing director’s annual remuneration. The employment agreements for Giles Campion, Luc Dochez and Berndt Modig provided for severance pay upon a termination of the managing director’s employment by us without cause in the amount of 50% of their annual remuneration. The employment agreement for Hans Schikan provided for severance pay upon termination of his employment by us without cause in the amount of 100% of his annual remuneration. Each employment agreement provided for a lump-sum payment following a change in control subject to certain conditions. That payment was equal to 130% of the individual’s annual gross fixed salary in effect at the time of the change in control for Giles Campion, Luc Dochez and Berndt Modig and 150% for Hans Schikan. In the event of a disability of a managing director, we were to continue to pay that managing director’s salary for an extended period up to 104 weeks. This obligation was to survive a termination of the employment agreement. The employment agreements contained post-termination restrictive covenants, including post-termination non-competition and non-solicitation covenants. These covenants typically lasted for a period of at least six months post-termination. In connection with the Acquisition, these agreements were terminated.
 
Long-term incentive plans
 
Prior to the Acquisition, we had certain share incentive plans in place. In connection with the Acquisition, all granted share-awards fully vested and these plans were terminated.
 
Share incentive plans
 
Pursuant to each of the 2004 Employee Stock Option Plan, the 2006 Employee Stock Option Plan, the 2007 Employee Stock Option Plan and the 2010 Equity Incentive Plan (collectively, the “Incentive Plans”), certain participants were granted the right to acquire (non-voting) depositary receipts (“Depositary Receipts”) issued in respect of our ordinary shares and/or cash settled instruments the value of which is linked to our ordinary shares (the “Awards”).
 
Upon the exercise or award or vesting of a non-cash -settled Award under the Incentive Plans, participants would receive ordinary shares upon the exercise or award or vesting of a non-cash -settled award under the Incentive Plans.
 
2010 Equity Incentive Plan
 
In 2010 we established the 2010 Equity Incentive Plan (“the 2010 Plan”) with the purpose of advancing the interests of our shareholders by enhancing our ability to attract, retain and motivate individuals who are expected to make important contributions to us and by providing those persons with performance- based incentives that are intended to better align their interests with those of our shareholders.
 
The outstanding Awards under the 2010 Plan covered up to 4,080,276 awards and the 2010 Plan permitted grants of Awards covering up to 4% of our outstanding ordinary shares each year from the date of the annual general meeting of shareholders until the date of the subsequent annual general meeting of shareholders.
 
Plan Administration . The 2010 Plan was administered by our management board. Approval of the supervisory board was required for all aggregate and significant individual grants of Awards under the 2010 Plan and the terms and conditions of exercise, vesting, purchase or repurchase in relation thereto.
 
Eligibility. All of our employees, managing directors and supervisory directors, as well as consultants, advisors and members of advisory committees were eligible to be granted Awards.
 
Awards. Awards included Options, SARs, Restricted Shares, Restricted Stock Units and Other Stock-Based Awards (each as defined below).
 
Share Options
 
Subject to the approval of the supervisory board, the management board could grant options to purchase ordinary shares (“Options”) and determine the number of shares to be covered by each Option, the exercise price of each Option and the conditions and limitations applicable to the exercise of each Option event. With respect to
 

 
Options with only service-based vesting conditions, 25% of the Options would on the first anniversary of the grant date, and the remaining 75% would vest in 36 equal monthly installments over a three year period following the first anniversary of the date of grant subject to continued employment of the relevant participant. With respect to Options with service-based vesting conditions combined with vesting conditions subject to our IPO, 25% of the Options would vest upon specified price thresholds of our ordinary shares, and 2.0833% would vest monthly thereafter subject to the continued employment of the relevant participant. Following the Acquisition, all Options immediately vested.
 
The exercise price was specified in the applicable Option agreement and could be less than, equal to, or greater than the fair market value per ordinary share on the date the Option was granted. The fair market value per ordinary share was based on the quoted market price of our ordinary shares. Each Option was exercisable at such times and subject to such terms and conditions as the management board would specify in the applicable Option agreement with a maximum term of ten years.
 
Stock Appreciation Rights
 
Subject to the approval of the supervisory board, the management board could grant Awards consisting of Stock Appreciation Rights (“SARs”) entitling the holder, upon exercise, to receive an amount of Depositary Receipts or cash or a combination thereof determined by reference to appreciation, from and after the date of grant, in the fair market value of an ordinary share over the measurement price established by the management board. The management board established the measurement price of each SAR and specified it in the applicable SAR agreement pursuant to an applicable formula. The measurement price could not be less than 100% of the fair market value on the date the SAR was granted. Each SAR was exercisable at such times and subject to such terms and conditions as the management board would specify in the applicable SAR agreement with a maximum term of ten years. We have never issued SARs.
 
Restricted Shares
 
Subject to the approval of the supervisory board, the management board could grant Awards entitling the holder to acquire Depositary Receipts (“Restricted Shares”), subject to our right to repurchase all or part of such Depositary Receipts at their issue price or other stated or formula price from the holder in the event that conditions specified by the management board in the applicable Award agreement were not satisfied prior to the end of the applicable restriction period or periods established by the management board for such Award. The management board determined the terms and conditions of a Restricted Share.
 
Restricted Stock Units
 
Subject to the approval of the supervisory board, the management board could grant Awards entitling the holder to receive ordinary shares or cash to be delivered at vesting (“Restricted Stock Units”). The management board determined the terms and conditions of a Restricted Stock Unit. Holders of Restricted Stock Units could be entitled to dividend equivalents. We have never issued Restricted Stock Units.
 
Other Stock -Based Awards
 
Other Awards of Depositary Receipts, and other Awards that were valued in whole or in part by reference to, or are otherwise based on, Depositary Receipts or other property, could be granted to participants (“Other Stock-Based Awards”). Such Other Stock-Based Awards were also available as a form of payment in the settlement of other Awards granted under the 2010 Plan or as payment in lieu of compensation to which a participant was otherwise entitled. Other Stock- Based Awards could be paid in Depositary Receipts or cash, as the management board determined. The management board determined the terms and conditions of each Other Stock-Based Award, including the conditions for vesting and repurchase and the issue price, if any. We have never issued Other Stock-Based Awards.
 
Amendment. Subject to the approval of the supervisory board, the management board could amend, suspend or terminate the 2010 Plan or any portion thereof at any time. Unless otherwise specified in the amendment, any amendment to the 2010 Plan would apply to, and be binding on the holders of, all Awards outstanding under the 2010 Plan at the time the amendment was adopted, provided the supervisory board determined that such amendment, taking into account any related action, did not materially and adversely affect the rights of participants
 

 
under the 2010 Plan. In addition, we could from time to time establish one or more sub -plans under the 2010 Plan for purposes of satisfying applicable securities, tax or other laws of various jurisdictions.
 
Prior stock option plans
 
In 2007 we established our 2007 Employee Stock Option Plan (as amended and restated in 2010, the “2007 Plan”), in 2006 we established our 2006 Employee Stock Option Plan (the “2006 Plan”) and in 2004 we established our 2004 Employee Stock Option Plan (the “2004 Plan,” and together with the 2007 Plan and the 2006 Plan, the “Prior Plans”). Each of the Prior Plans permitted the grant of options (“Options”) to purchase Depositary Receipts. The Options were subject to transfer restrictions. Each of the Prior Plans was terminated at our annual general meeting of shareholders on June 14, 2013.
 
Plan Administration . Under each of the Prior Plans, an Option would be granted with the approval of the supervisory board and was evidenced by an Option agreement signed by the participant to indicate his acceptance of its terms and conditions. We have not issued any future Options under any of the Prior Plans.
 
Eligibility. Under the 2006 Plan, Options could only be granted to an employee or a supervisory board member. Under the 2007 Plan and 2004 Plan, Options could be granted to an employee, a supervisory board member or a scientific advisory board member.
 
Option Exercise Price. The exercise price to acquire one Depositary Receipt upon exercise of an Option was determined by the management board in its sole discretion upon granting the Options.
 
Vesting Period. Under each of the Prior Plans, the option period commenced at the date of grant and lasted ten years. Under the 2007 Plan, generally 25% of the Depositary Receipts underlying Options vested on the first anniversary of the grant date, and 2.0833% vested monthly thereafter. Under each of the 2006 Plan and the 2004 Plan, generally all the Depositary Receipts underlying Options vested immediately, with us having the right to repurchase a portion of the underlying Depositary Receipts if the employee or supervisory board member left within four years of the grant date. As a result of the Acquisition, all Options under the Prior Plans immediately vested.
 
Amendment. Subject to the approval of our shareholders and the supervisory board, we were authorized to amend each of the Prior Plans at any time and in any manner we deemed fit. We have not amended any of the Prior Plans.
 
Compensation of managing directors and supervisory directors
 
Dutch law provides that we must establish a policy in respect of the remuneration of our managing directors. As a result of the Acquisition, BioMarin will determine the future remuneration of our managing directors.

Insurance and indemnification
 
Managing directors and supervisory directors have the benefit of indemnification provisions in our Articles of Association. These provisions give managing directors and supervisory directors the right, to the fullest extent permitted by law, to recover from us amounts, including but not limited to litigation expenses, and any damages they are ordered to pay, in relation to acts or omissions in the performance of their duties. However, there is generally no entitlement to indemnification for acts or omissions that amount to willful (opzettelijk), intentionally reckless (bewust roekeloos) or seriously culpable (ernstig verwijtbaar) conduct. In addition, we have entered into agreements with our managing directors and supervisory directors to indemnify them against expenses and liabilities to the fullest extent permitted by law. These agreements also provide, subject to certain exceptions, for indemnification for related expenses including, among others, attorneys’ fees, judgments, penalties, fines and settlement amounts incurred by any of these individuals in any action or proceeding. In addition to such indemnification, we provide our managing directors and supervisory directors with directors’ and officers’ liability insurance.
 
Insofar as indemnification of liabilities arising under the Securities Act may be permitted to supervisory directors, managing directors or persons controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Supervisory board
 
Supervisory directors are appointed by the general meeting of shareholders upon a binding nomination of the supervisory board for a term of up to four years. As a result of the Acquisition, BioMarin will determine future nominations of our supervisory directors.
 
Our Articles of Association provide for a term of appointment of supervisory directors of up to four years. Our supervisory directors have been appointed for different terms as a result of which only approximately one-third of our supervisory board members will be subject to election in any one year. Such an appointment has the effect of creating a staggered board and may deter a takeover attempt.
 
The supervisory board meets as often as a supervisory board member deems necessary. In a meeting of the supervisory board, each supervisory director has a right to cast one vote. All resolutions by the supervisory board are adopted by an absolute majority of the votes cast. In the event the votes are equally divided, the chairman has a decisive vote. A supervisory director may grant another supervisory director a written proxy to represent him at the meeting, but a supervisory director cannot represent more than one supervisory director.
 
Our supervisory board can pass resolutions outside of meetings, provided that the resolution is adopted in writing and all supervisory directors have consented to adopting the resolution outside of a meeting. The chairman shall prepare and sign a report of the resolutions adopted in this manner.
 
Our supervisory directors do not have a retirement age requirement under our Articles of Association.
 
Management board
 
The supervisory board determines the number of managing directors. Managing directors are appointed by the general meeting of shareholders upon a binding nomination of the supervisory board for a term of up to four years. As a result of the Acquisition, BioMarin will determine future appointments of our managing directors.
 
At least once per year the management board informs the supervisory board in writing of the main lines of our strategic policy, the general and financial risks and the management and control system.
 

 
Supervisory Board Committees
 
Upon the Closing, our supervisory board dissolved our committees.
 
Audit committee
 
Until January 15, 2015, the audit committee consisted of Daan Ellens, Michael Wyzga and Georges Gemayel. Mr. Wyzga served as Chairman of the committee. The audit committee consisted exclusively of members of our supervisory board who are financially literate, and Michael Wyzga and Daan Ellens were considered an “audit committee financial expert” as defined by the SEC. In addition, under SEC and Nasdaq rules, there are heightened independence standards for members of the audit committee, including a prohibition against the receipt of any compensation from us other than standard supervisory director fees. All of our audit committee members met this heightened standard. The audit committee was governed by a charter that complied with Nasdaq rules.
 
The audit committee was responsible for:
 
 
·
recommending the appointment of the independent auditor to the general meeting of shareholders;
 
 
·
the appointment, compensation, retention and oversight of any accounting firm engaged for the purpose of preparing or issuing an audit report or performing other audit services;
 
 
·
pre-approving the audit services and non-audit services to be provided by our independent auditor before the auditor is engaged to render such services;
 
 
·
evaluating the independent auditor’s qualifications, performance and independence, and presenting its conclusions to the full supervisory board on at least an annual basis;
 
 
·
reviewing and discussing with the management board and the independent auditor our annual audited financial statements and quarterly financial statements prior to the filing of the respective annual and quarterly reports;
 
 
·
reviewing our compliance with laws and regulations, including major legal and regulatory initiatives and also reviewing any major litigation or investigations against us that may have a material impact on our financial statements; and
 
 
·
approving or ratifying any related person transaction (as defined in our related person transaction policy) in accordance with our related person transaction policy.
 
Compensation committee
 
Until January 15, 2015, the compensation committee consisted of David Mott, Daan Ellens and Georges Gemayel. Mr. Mott served as Chairman of the committee. The committee recommended to the supervisory board for determination the compensation of each of our managing directors. Under Nasdaq rules, there are heightened independence standards for members of the compensation committee, including a prohibition against the receipt of any compensation from us other than standard supervisory director fees. All of our compensation committee members met this heightened standard.
 
The compensation committee was responsible for:
 
 
·
identifying, reviewing and approving corporate goals and objectives relevant to management board compensation;
 
 
·
analyzing the possible outcomes of the variable remuneration components and how they may affect the remuneration of the managing directors;
 
 
·
evaluating each managing director’s performance in light of such goals and objectives and determining each managing director’s compensation based on such evaluation;
 

 
 
·
determining any long-term incentive component of each managing director’s compensation in line with the remuneration policy and reviewing our management board compensation and benefits policies generally;
 
 
·
periodically reviewing, in consultation with our Chief Executive Officer, our management succession planning; and
 
 
·
reviewing and assessing risks arising from our compensation policies and practices for our employees and whether any such risks are reasonably likely to have a material adverse effect on us.
 
 
As of December 31, 2014, we had 95 employees. None of our employees is subject to a collective bargaining agreement or represented by a trade or labor union. We established a workers’ council for our employees effective as of February 2014. We consider our relations with our employees to be good.
 
 
See “Item 7. Major Shareholders and Related Party Transactions—A. Major shareholders.”
 
 
 
BioMarin Acquisition
 
On January 15, 2015, BioMarin announced the Closing by subsidiaries of BioMarin to purchase all of our issued and outstanding ordinary shares, nominal value €0.01 per share. On February 5, 2015, Prosensa and BioMarin Falcons B.V. entered into the Asset Sale agreement that closed on February 12, 2015, pursuant to which BioMarin Falcons B.V. or its designee acquired all of Prosensa’s assets and assumed all of Prosensa’s liabilities. On February 11, 2015, we filed a Form 25, Notification of Removal from Listing and/or Registration, under Section 12(b) of the Securities Exchange Act of 1934 with the SEC in order to voluntarily delist our registered shares from the NASDAQ Global Select Market, which became effective 10 days after filing. NASDAQ suspended trading of our shares after the market closed on February 11, 2015. By reason of the Closing and Asset Sale, our managing and supervisory directors no longer hold ordinary shares. As of February 10, 2015, BioMarin owned approximately 96.8% of our ordinary shares.
 
Significant Changes in Ownership by Major Shareholders
 
We have recently experienced significant changes in the percentage ownership held by major shareholders as a result of the Closing and Asset Sale. Prior to the Closing and Asset Sale, our principal shareholders were entities affiliated with Abingworth Partners, New Enterprise Associates 13, Limited Partnership, Deerfield Management, Life Sciences Partners, Kempen Capital Management, Idinvest Partners and Gimv N.V.
 
Holders
 
As of March 23, 2015, the date we requested the deregistration of our ordinary shares with the SEC, we had approximately 59 holders of record of our ordinary shares.
 
 
The following is a description of related party transactions we have entered into since January 1, 2011 with any of our members of our supervisory board or management board and the past holders of more than 5% of our ordinary shares.
 
BioMarin Acquisition
 
See “Item 7.A—Major shareholders—BioMarin Acquisition” above.
 

 
Shareholders’ agreement
 
On December 8, 2008, all of our then existing shareholders entered into a shareholders agreement, as amended on June 29, 2010 and January 16, 2012 (as amended, the “Shareholders’ Agreement”).  The Shareholders' Agreement governed the composition of our board of directors and provided anti-dilution and preemptive rights. The Shareholders' Agreement was terminated in connection with our initial public offering in July 2013.
 
Equity Incentive Plans and Foundation
 
See “Item 6—B. Compensation—Long-term incentive plans.”
 
Registration rights agreement
 
Following the consummation of our IPO, we entered into a registration rights agreement with certain of our existing shareholders pursuant to which we granted them certain registration rights.  The agreement is no longer applicable there are no longer any outstanding “registrable securities” as defined under the agreement.
 
Indemnification Agreements
 
We have entered into indemnification agreements with our managing directors and supervisory directors. The indemnification agreements and our Articles of Association require us to indemnify our managing directors and supervisory directors to the fullest extent permitted by law. See “Item 6B. Compensation – Insurance and Indemnification” for a description of these indemnification agreements.
 
 
Not applicable.
 
 
 
Financial statements
 
See “Item 18. Financial Statements,” which contains our financial statements prepared in accordance with IFRS.
 
Legal Proceedings
 
From time to time we are involved in legal proceedings that arise in the ordinary course of business. We believe that the outcome of these proceedings, if determined adversely, will not have a material adverse effect on our financial position. During the period covered by the audited and approved financial statements contained herein, we have been a party to a purported class action lawsuit. The litigation is in its earliest stages, and we intend to defend the action vigorously. We have not paid any damages in connection with the litigation nor are we able at present to reasonably estimate potential losses. An adverse resolution could have a material adverse effect on our financial position.
 
Dividends and Dividend Policy
 
We have not declared cash dividends on our common stock in the years 2014, 2013 or 2012. In conjunction with the Asset Sale, we made an advance liquidation distribution to our remaining shareholders, with each remaining shareholder receiving a cash payment equal to $17.75 per share as well as one contingent value right to receive cash payments of up to $4.14 per share in the aggregate upon the achievement of the right to market and sell drisapersen in the United States and in the European Union, without interest thereon and less any applicable withholding taxes.

The following summary contains a description of certain Dutch and U.S. federal income tax consequences of the acquisition, ownership and disposition of ordinary shares, but it does not purport to be a comprehensive description of all the tax considerations that may be relevant to a decision to purchase ordinary shares. The summary is based upon the tax laws of the Netherlands and regulations thereunder and on the tax laws of the United States and regulations thereunder as of the date hereof, which are subject to change.
 
Dutch Tax considerations
 
The following discussion is a summary of the material Dutch tax considerations relating to the purchase, ownership and disposition of our ordinary shares.
 
Taxation in the Netherlands
 
The following is intended as general information only and it does not purport to present any is not a comprehensive or complete description of all aspects of Dutch tax law which could be of relevance to a holder of ordinary shares (a “Shareholder”). For Dutch tax purposes, a Shareholder may include an individual who or an entity that does not have the legal title of the shares, but to whom nevertheless the shares are attributed based either on such individual or entity holding a beneficial interest in the shares or based on specific statutory provisions. These include s, including statutory provisions pursuant to which shares are attributed to an individual who is, or who has directly or indirectly inherited from a person who was, the settlor, grantor or similar originator of a trust, foundation or similar entity that holds the shares.
 
Prospective Shareholders should consult their tax adviser regarding the tax consequences of any purchase, ownership or disposal of ordinary shares.
 
The following summary is based on the Dutch tax law as applied and interpreted by Dutch tax courts and as published and in effect on the date hereof, without prejudice to any amendments introduced at a later date and implemented with or without retroactive effect.
 
For the purpose of this paragraph, “Dutch Taxes” shall mean taxes of whatever nature levied by or on behalf of the Netherlands or any of its subdivisions or taxing authorities. The Netherlands means the part of the Kingdom of the Netherlands located in Europe.
 
Any reference hereafter made to a treaty for the avoidance of double taxation concluded by the Netherlands includes the Tax Regulation for the Kingdom of the Netherlands (Belastingregeling voor het Koninkrijk), the Tax Regulation for the country of the Netherlands (Belastingregeling voor het land Nederland) and the Agreement between the Taipei Representative Office in the Netherlands and the Netherlands Trade and Investment Office in Taipei for the avoidance of double taxation.
 
Withholding Tax
 

 
A Shareholder is generally subject to Dutch dividend withholding tax at a rate of 15% on dividends distributed by the company. Generally, the company is responsible for the withholding of such dividend withholding tax at source; the dividend withholding tax is for the account of the Shareholder.
 
Dividends distributed by the company include, but are not limited to:
 
 
·
distributions of profits in cash or in kind, whatever they be named or in whatever form
 
 
·
proceeds from the liquidation of the company, or proceeds from the repurchase of ordinary shares by the company, in excess of the average paid-in capital recognized for Dutch dividend withholding tax purposes
 
 
·
the nominal value of ordinary shares issued to a Shareholder or an increase in the nominal value of ordinary shares, to the extent that no contribution, recognized for Dutch dividend withholding tax purposes, has been made or will be made; and
 
 
·
partial repayment of paid-in capital, that is
 
 
o
not recognized for Dutch dividend withholding tax purposes, or
 
 
o
recognized for Dutch dividend withholding tax purposes, to the extent that the company has “net profits” (zuivere winst), unless
 
 
(a) 
the general meeting of Shareholders has resolved in advance to make such repayment, and
 
 
(b)
the nominal value of the ordinary shares concerned has been reduced with an equal amount by way of an amendment to the Articles of Association of the company.
 
The term “net profits” includes anticipated profits that have yet to be realized.
 
Notwithstanding the above, no withholding is required in the event of a repurchase of ordinary shares, if certain conditions are fulfilled.
 
If a Shareholder is resident or deemed to be resident in the Netherlands such Shareholder is generally entitled to an exemption or a full credit for any Dutch dividend withholding tax against his Dutch (corporate) income tax liability and to a refund of any residual Dutch dividend withholding tax.
 
If a Shareholder is resident in a country other than the Netherlands under circumstances exemptions from, reduction in or refunds of, dividend withholding tax may be available pursuant to Dutch domestic law or treaties or regulations for the avoidance of double taxation.
 
According to Dutch domestic anti-dividend stripping rules, no credit against Dutch (corporate) income tax, exemption from, reduction in or refund of, Dutch dividend withholding tax will be granted if the recipient of the dividend paid by the company is not considered to be the beneficial owner (uiteindelijk gerechtigde) of such dividends as meant in these rules.
 
Taxes on income and capital gains
 
This section does not describe the possible Dutch tax considerations or consequences that may be relevant to a Shareholder:
 
 
·
who is an individual and for whom the income or capital gains derived from the ordinary shares are attributable to employment activities, the income from which is taxable in the Netherlands
 
 
·
that is an entity which is, pursuant to the Dutch Corporate Income Tax Act 1969 (Wet op de vennootschapsbelasting 1969, "CITA") , not subject to Dutch corporate income tax or is in full or in part exempt from Dutch corporate income tax (such as a qualifying pension fund);
 
 
·
that is an investment institution (beleggingsinstelling) as defined in article 6a or 28 CITA; or
 

 
 
·
which is entitled to the participation exemption (deelnemingsvrijstelling) with respect to the ordinary shares as defined in article 13 CITA.
 
Residents in the Netherlands
 
The description of certain Dutch tax consequences in this paragraph is only intended for the following Shareholders:
 
(a)     individuals who are resident or deemed to be resident in the Netherlands for Dutch income tax purposes (“Dutch Individuals”); and
 
(b)     entities that are subject to the CITA and are resident or deemed to be resident in the Netherlands for corporate income tax purposes “Dutch Corporate Entities”).
 
Dutch Individuals engaged or deemed to be engaged in an enterprise or in miscellaneous activities
 
Dutch Individuals are generally subject to income tax at statutory progressive rates with a maximum of 52% (2015) with respect to any benefits derived or deemed to be derived from Dutch Enterprise Shares (as defined below), including any capital gains realized on the disposal thereof.
 
“Dutch Enterprise Shares” are shares or any right to derive benefits from shares:
 
 
·
which are attributable to an enterprise from which a Dutch Individual derives profits, whether as an entrepreneur (ondernemer) or pursuant to a co-entitlement to the net worth of such enterprise (other than as an entrepreneur or a shareholder); or
 
 
·
of which the benefits are taxable in the hands of a Dutch Individual as benefits from miscellaneous activities (resultaat uit overige werkzaamheden) including, without limitation, activities which are beyond the scope of active portfolio investment management.
 
Dutch Individuals having a (fictitious) substantial interest
 
Dutch Individuals are generally subject to income tax at statutory rate of 25% (2015) with respect to any benefits derived or deemed to be derived from shares, excluding Dutch Enterprise Shares, (including any capital gains realized on the disposal thereof) that are attributable to a (fictitious) substantial interest (such shares being “Substantial Interest Shares”).
 
Generally, a Shareholder has a substantial interest (aanmerkelijk belang) in the company if such Shareholder, alone or together with his partner, directly or indirectly:
 
 
·
owns, or holds certain rights on, shares representing 5% or more of the total issued and outstanding capital of the company, or of the issued and outstanding capital of any class of shares of the company;
 
 
·
holds rights to, directly or indirectly, acquire shares, whether or not already issued, representing 5% or more of the total issued and outstanding capital of the company, or of the issued and outstanding capital of any class of shares of the company; or
 
 
·
owns, or holds certain rights on, profit participating certificates that relate to 5% or more of the annual profit of the company or to 5% or more of the liquidation proceeds of the company.
 
A Shareholder will also have a substantial interest if his partner or one of certain relatives of the Shareholder or of his partner has a substantial interest.
 
Generally, a Shareholder has a fictitious substantial interest (fictief aanmerkelijk belang) in the company if, without having an actual substantial interest in the company:
 
 
·
an enterprise has been contributed to the company in exchange for shares on an elective non-recognition basis;
 

 
 
·
the shares have been obtained under gift law, inheritance law or matrimonial law, on a non-recognition basis, while the previous Shareholder had a substantial interest in the company;
 
 
·
the shares have been acquired pursuant to a share merger, legal merger or legal demerger, on an elective non-recognition basis, while the Shareholder prior to this transaction had a substantial interest in an entity that was party thereto; or
 
 
·
the shares held by the Shareholder, prior to dilution, qualified as a substantial interest and, by election, no gain was recognized upon disqualification of these shares.
 
Dutch Individuals not engaged or deemed to be engaged in an enterprise or in miscellaneous activities or having a (fictitious) substantial interest
 
Generally, a Dutch Individual who owns shares, excluding Dutch Enterprise Shares and Substantial Interest Shares, will be subject annually to an income tax imposed on a fictitious yield on such shares under the regime for savings and investments (inkomen uit sparen en beleggen). Irrespective of the actual income or capital gains realized, the annual taxable benefit of all the assets and liabilities of a Dutch Individual that are taxed under this regime, including the shares, is set at a fixed amount. The fixed amount equals 4% (2015) of the fair market value of the assets reduced by the liabilities and measured, in general, exclusively at the beginning of every calendar year. The tax rate under the regime for savings and investments is a flat rate of 30% (2015).
 
Dutch Corporate Entities
 
Dutch Corporate Entities are generally subject to corporate income tax at statutory rates up to 25% (2015) with respect to any benefits derived or deemed to be derived (including any capital gains realized on the disposal) of shares.
 
Non-residents in the Netherlands
 
A Shareholder other than a Dutch Individual or Dutch Corporate Entity, will not be subject to any Dutch Taxes on income or capital gains with respect to the ownership and disposal of the shares, other than dividend withholding tax as described above, except if:
 
 
·
the Shareholder derives profits from an enterprise, whether as entrepreneur (ondernemer) or pursuant to a co-entitlement to the net worth of such enterprise other than as an entrepreneur or a Shareholder, which enterprise is, in whole or in part, carried on through a permanent establishment or a permanent representative (vaste vertegenwoordiger) in the Netherlands, to which the shares are attributable;
 
 
·
the Shareholder is an individual and derives benefits from miscellaneous activities carried out in the Netherlands in respect of the shares, including, without limitation, activities which are beyond the scope of active portfolio investment management;
 
 
·
the Shareholder is an individual and has a substantial interest or a fictitious substantial interest in the company, which (fictitious) substantial interest is not attributable to the assets of an enterprise;
 
 
·
the Shareholder is not an individual and has a substantial interest or a fictitious substantial interest in the company, which (fictitious) substantial interest is not attributable to the assets of an enterprise and (one of) the main purposes of the chosen ownership structure is the evasion of Dutch income tax or dividend withholding tax.
 
 
·
the Shareholder is an individual and is entitled to a share in the profits of an enterprise, other than by way of the holding securities, which enterprise is effectively managed in the Netherlands and to which enterprise the shares are attributable; or
 
 
·
the Shareholder is not an individual and is entitled to a share in the profits of an enterprise or a co-entitlement to the net worth of an enterprise, other than by way of the holding of securities, which enterprise is effectively managed in the Netherlands and to which enterprise the shares are attributable.
 
Gift tax and inheritance tax
 

 
No Dutch gift or inheritance tax is due in respect of any gift of the shares by, or inheritance of the shares on the death of, a Shareholder, except if:
 
 
·
at the time of the gift or death of the Shareholder, the Shareholder is resident, or is deemed to be resident, in the Netherlands
 
 
·
the Shareholder passes away within 180 days after the date of the gift of the shares and is not, or not deemed to be, at the time of the gift, but is, or deemed to be, at the time of his death, resident in the Netherlands; or
 
 
·
the gift of the shares is made under a condition precedent and the Shareholder is resident, or is deemed to be resident, in the Netherlands at the time the condition is fulfilled.
 
For purposes of Dutch gift or inheritance tax, an individual who is of Dutch nationality will be deemed to be resident in the Netherlands if he has been resident in the Netherlands at any time during the ten years preceding the date of the gift or his death. For purposes of Dutch gift tax, any individual, irrespective of his nationality, will be deemed to be resident in the Netherlands if he has been resident in the Netherlands at any time during the 12 months preceding the date of the gift.
 
Other Taxes and Duties
 
No other Dutch Taxes, including turnover tax and taxes of a documentary nature, such as capital tax, stamp or registration tax or duty, are payable by or on behalf of a Shareholder by reason only of the purchase, ownership and disposal of the ordinary shares.
 
Residency
 
A Shareholder will not become resident, or deemed resident in the Netherlands for tax purposes by reason only of holding the ordinary shares.
 
U.S. federal income tax considerations for U.S. holders
 
Following the Acquisition and in conjunction with the Asset Sale, we made an advance liquidation distribution to our remaining shareholders. As a result of the advance liquidation distribution and the Post-Closing Reorganization, we have limited assets, no further distributions are expected to be made and our ordinary shares are expected to have little to no value. The Post-Closing Reorganization, including the Asset Sale and our subsequent dissolution and liquidation, is a process available to BioMarin under Dutch law.

Stichting Prosensa, a foundation (stichting) organized and existing under Dutch law, has been appointed as the liquidator to carry out the liquidation of our remaining assets once our dissolution has become effective. U.S. holders of our ordinary shares should consult their own tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of ordinary shares in their particular circumstances, including the consequences of receiving cash and contingent value rights pursuant to the advance liquidation distribution.

On March 23, 2015, we filed a Form 15 with the SEC under the Exchange Act, requesting the deregistration of our ordinary shares under the Exchange Act and the suspension of our reporting obligations under the Exchange Act. We have not arranged (nor are we planning to arrange) for the listing of our ordinary shares on another U.S. securities exchange or for quotation of the ordinary shares on any other quotation medium in the United States.
 

 
Prior to such date, we were subject to the informational requirements of the Exchange Act. Accordingly, we were required to file reports and other information with the SEC, including annual reports on Form 20-F and reports on Form 6-K. You may inspect and copy reports and other information filed with the SEC at the Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549. Information on the operation of the Public Reference Room may be obtained by calling the SEC at 1-800-SEC-0330. In addition, the SEC maintains an Internet website that contains reports and other information about issuers, like us, that file electronically with the SEC. The address of that website is www.sec.gov.
 
 
Not applicable.
 
 
Until the Acquisition, we were exposed to a variety of financial risks: market risk (including foreign exchange risk and interest rate risk), credit risk and liquidity risk. Our overall risk management program focused on the unpredictability of financial markets. Following the Acquisition, we expect to be part of BioMarin’s risk management program.
 
Market risk
 
We were exposed to foreign exchange risk arising from various currency exposures, primarily with respect to the U.S. dollar. Until December 31, 2014, our functional currency was the euro, but we acquired materials in U.S. dollars. No formal practice was established to manage the foreign exchange risk against our functional currency. As of December 31, 2014, there was outstanding a net liability in US dollars of €12.5 million.
 
Our interest rate risk arose from long-term borrowings that were issued at variable rates. This risk was partially offset by cash held at variable rates. Borrowings issued at fixed rates exposed us to interest rate risk. During 2014, 2013 and 2012, our borrowings were mainly denominated in euros.
 
If interest rates on borrowings had been 0.1% higher/lower with all other variables held constant, after-tax total comprehensive loss for all the periods presented would have been less than €0.1 million lower/higher as a result of changes in the fair value of the borrowings. The effect of a change in interest rates of 0.1% on borrowings would have had an insignificant effect on after-tax total comprehensive loss for the year.
 
Credit Risk
 
GSK funding (milestone payments, collaboration revenue and reimbursable research expenses) has been critical for our product development programs and until the termination of our agreement with GSK, we considered it the main credit risk. We had a limited group of external counterparties of which the most significant was GSK. We managed credit risk on a group basis.
 
Our cash and cash equivalents were invested primarily in saving and deposit accounts with original maturities of three months or less. Saving and deposit accounts generated interest income. For banks and financial institutions, only independently rated parties with a minimum rating of ‘A’ were accepted at the beginning of the term.
 
We did business with a limited group of external parties. If external parties were independently rated, these ratings were used. If there is no independent rating, the credit quality of these parties was assessed, taking into account their financial position, past experience and other factors. As of December 31, 2014 no credit limits had been exceeded since the beginning of 2011. We have not incurred any losses over the reporting period.
 
Liquidity Risk
 
Following the Asset Sale and advance liquidation distribution in February 2015, Prosensa has limited assets and the ordinary shares are expected to have little to no value.

Our managing board, including our chief executive officer and chief financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of December 31, 2014, have concluded that based on the evaluation of these controls and procedures required by Rule 13a-15(b) of the Exchange Act, our disclosure controls and procedures were effective.
 
 
Our management is responsible for establishing and maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting.
 
Internal control over financial reporting is defined in rules 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the audited consolidated financial statements.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect material misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. The effectiveness of our internal control over financial reporting as of December 31, 2014, is based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission. Based on those criteria, management has concluded that as of December 31, 2014, the Company’s internal control over financial reporting is effective.
 
 
This annual report does not include an attestation report of our registered public accounting as we are an emerging growth company.
 

 
 
There has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the period covered by this Annual Report that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting.
 
 
 
Our supervisory board had determined that Daan Ellens and Michael Wygza, independent directors, were audit committee financial experts, as that term is defined by the SEC, until their resignation from the supervisory board on January 15, 2015. On February 11, 2015, we filed a Form 25, Notification of Removal from Listing and/or Registration, under Section 12(b) of the Securities Exchange Act of 1934 with the SEC in order to voluntarily delist our shares from the NASDAQ Global Select Market, which became effective 10 days after filing. NASDAQ suspended trading of our shares after the market closed on February 11, 2015. Following the delisting, as a non-listed company and majority-owned subsidiary of BioMarin, we intend to follow the internal policies of BioMarin that are applicable to majority-owned subsidiaries. We no longer have an audit committee or an audit committee financial expert.
 
 
Code of Business Conduct and Ethics
 
At the time of our initial public offering, we adopted a Code of Business Conduct and Ethics which covered a broad range of matters including the handling of conflicts of interest, compliance issues and other corporate policies such as insider trading and equal opportunity and non-discrimination standards. Until the Closing, our Code of Business Conduct applied to all of our supervisory directors, managing directors and employees. Our supervisory directors, managing directors and employees are now subject to BioMarin’s corporate compliance and ethics program.
 
 
The information required under by item 16C is included in note 32 of the consolidated financial statements in Item 18 of Part III.

In 2014, no purchases of our equity securities were made by or on behalf of Prosensa or any affiliated purchaser.

Summary of Significant Corporate Governance Differences From Nasdaq Listing Standards
 
Our ordinary shares were previously listed on the Nasdaq Global Select Market, or Nasdaq. We were therefore required to comply with certain of the Nasdaq’s corporate governance listing standards, or the Nasdaq Standards. As a foreign private issuer, we were able to follow our home country’s corporate governance practices in lieu of certain of the Nasdaq Standards. Our corporate governance practices differed in certain respects from those that U.S. companies must adopt in order to maintain a Nasdaq listing. On February 11, 2015, we filed a Form 25, Notification of Removal from Listing and/or Registration, under Section 12(b) of the Securities Exchange Act of 1934 with the SEC in order to voluntarily delist our shares from the NASDAQ Global Select Market, which became effective 10
 

 
days after filing. NASDAQ suspended trading of our shares after the market closed on February 11, 2015. Following the delisting, we are no longer subject to the Nasdaq Standards.

To Management Board and shareholders of Prosensa Holding N.V. in liquidatie

In our opinion, the accompanying consolidated balance sheets and the related consolidated statement of comprehensive income, changes in equity and cash flows present fairly, in all material respects, the financial position of Prosensa Holding N.V.in liquidatie  and its subsidiaries at December 31, 2014 and December 31, 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.  These financial statements are the responsibility of the Company’s management.  Our responsibility is to express an opinion on these financial statements based on our audits.  We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and International Standards on Auditing.  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

Emphasis on liquidation of the company
 
As described in note 2.1, the company has transferred all the assets and liabilities following the acquisition by Biomarin and the legal entity is in liquidation. Our opinion is not qualified in respect of this matter.

1.
General information
 
Prosensa Holding N.V. in liquidatie (together with its subsidiaries referred to as the Company here from), BioMarin Falcons B.V. and BioMarin Pharmaceutical Inc. have entered into a purchase agreement dated November 23, 2014 (the Purchase Agreement). Pursuant to the Purchase Agreement, BioMarin Falcons B.V. together with BioMarin Giants B.V. has made a tender offer (the Offer) for all the outstanding ordinary shares with a nominal value of € 0.01 in exchange for:
 
 
(i)
USD 17.75 per Share, in cash, without interest (the Cash Consideration) and
 
 
(ii)
one contingent value right (a CVR) which shall represent the right to receive the Milestone Payments, if any, at the times provided for in the Contingent Value Rights Agreement, per Share, without interest.
 
Approximately 96.76% of Prosensa Holding’s Shares have been purchased by BioMarin Falcons B.V. and BioMarin Giants B.V. (‘purchasers’), pursuant to the tender offer completed on January 15, 2015 including the extended Offer period ended January 29, 2015.
 
Simultaneously with the entering into the Purchase Agreement, the management board and the supervisory board have resolved to approve the sale and transfer of the Company’s all assets and liabilities to BioMarin Falcons B.V. (the Purchaser). At an extraordinary general meeting of shareholders held on January 13, 2015, the shareholders of the Company have approved, among other things, the sale and transfer of all the assets and liabilities of the Company to the Purchaser and the dissolution (ontbinding) and subsequent liquidation (vereffening) of the Company in accordance with article 2:19 of the Dutch Civil Code. Following the closing of the Offer and the Subsequent Offer Period, the Parties after due and careful consideration have decided to pursue the Asset Sale. On February 5, the Company and BioMarin Falcons B.V. signed an asset sale agreement (‘sale agreement’) for the sale of all assets and liabilities of the Company, which assets and liabilities encompass all business of the Company. The Company went into liquidation on February 12, 2015, immediately following the closing of the sale of the Business to BioMarin Falcons B.V.
 
On February 11, 2015, the Company filed a Form 25, Notification of Removal from Listing and/or Registration, under Section 12(b) of the Securities Exchange Act of 1934 with the SEC in order to voluntarily delist the shares from the NASDAQ Global Select Market, which became effective 10 days after filing. NASDAQ suspended trading of the shares after the market closed on February 11, 2015.
 
On February 12, 2015, the Liquidator has paid out an amount of USD 17.75 plus one CVR per share to the holders of 36,141,379 outstanding shares in the Company, less any applicable Dutch withholding tax (which will be duly declared and paid to the Dutch tax authorities). The settlement was funded from the amounts paid or made available by the Purchaser to the Company under the sale agreement. This distribution concerned an advance liquidation distribution at 100% of the net proceeds of the sale of the Company’s business. Following the sale and transfer of the Business, there are no outstanding liabilities of the Company related to the Business, nor are there any other liabilities of the Company that have not been transferred or adequately provided for. Under the sale agreement, Purchaser will be entitled to any amount that would remain of these advances after completion of the liquidation process.
 
Until February 12, 2015, the activities of the Company primarily consisted of developing innovative, RNA-based therapeutics for the treatment of genetic disorders. The Company was incorporated and domiciled in the Netherlands. The address of its registered office was J.H. Oortweg 21, Leiden. Prosensa Holding N.V. was the ultimate parent of the following group of entities:
 
1.
Prosensa Therapeutics B.V. (100%);
 
2.
Prosensa Technologies B.V. (100%);
 
3.
Polybiotics B.V. (100%); and
 
4.
Prosensa Inc. (100%)
 

 
Effective January 12, 2014, GlaxoSmithKline (GSK) and the Company mutually agreed to terminate the Research and Development Collaboration and License agreement (the research and collaboration agreement) entered into on October 6, 2009. As of the effective date, the Company regained all rights for the development and commercialization of drisapersen, PRO044 and other applicable compounds in its Duchenne muscular dystrophy (“DMD”) portfolio.
 
The Management Board approved the consolidated financial statements for issuance on April 30, 2015. The Management Board has been duly authorized to do so by the Company’s owners. The Company will not hold any shareholder’s meetings after issue of these financial statements.
 
2. Summary of significant accounting policies
 
The principal accounting policies applied in the preparation of these consolidated financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.
 
2.1 Basis of preparation
 
The consolidated financial statements of the Company have not been prepared on a going concern basis due to the reorganization of the Company as a result of the BioMarin acquisition. The Company is currently in liquidation and will cease to exist. As the Company transferred all of the assets and liabilities to another legal entity which is part of the Biomarin group and the fair value of the assets exceeded their carrying amounts, no adjustments were made to the accompanying financial statements as a result of the transfer.
 
The consolidated financial statements of Prosensa have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). There are no material differences between IFRS as adopted by the European Union and IFRS as issued by the IASB. The consolidated financial statements have been prepared under the historical cost convention, as modified by derivative instruments at fair value through profit or loss.
 
The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It requires management to exercise its judgment in the process of applying the Company’s accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in note 4.
 
2.2 Changes in accounting policy and disclosures
 
(a) New and amended standards adopted by the Company
 
The following standards and amendments to standards became effective for annual periods on January 1, 2014, and have been adopted by the Company in the preparation of the consolidated financial statements:
 
 
·
Amendment to IAS 32 Financial instruments: presentation
 
 
·
Amendment to IAS 36 Impairment of Assets
 
 
·
Amendment to IAS 39 Financial Instruments
 
 
·
IFRIC 21 Levies
 
The adoption of these new standards and amendments to standards had an immaterial effect on the Company’s financial position and results of operations in the periods presented.
 
(b) New standards and interpretations not yet adopted by the Company

 
IFRS 15 “Revenue from contracts with customers” is effective as from January 1, 2017 with a retrospective effect and could have a significant effect on the consolidated financial statements of the Company. IFRS 15, ‘Revenue from contracts with customers’ deals with revenue recognition and establishes principles for reporting useful information to users of financial statements about the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. Revenue is recognized when a customer obtains control of a good or service and thus has the ability to direct the use and obtain the benefits from the good or service. The Company has not early adopted IFRS 15 and has yet to assess IFRS 15’s full impact.
 
IFRS 9, ‘Financial instruments’, addresses the classification, measurement and recognition of financial assets and financial liabilities. The complete version of IFRS 9 was issued in July 2014. It replaces the guidance in IAS 39 that relates to the classification and measurement of financial instruments. IFRS 9 retains but simplifies the mixed measurement model and establishes three primary measurement categories for financial assets: amortized cost, fair value through OCI and fair value through P&L. The basis of classification depends on the entity’s business model and the contractual cash flow characteristics of the financial asset. Investments in equity instruments are required to be measured at fair value through profit or loss with the irrevocable option at inception to present changes in fair value in OCI not recycling. There is now a new expected credit losses model that replaces the incurred loss impairment model used in IAS 39. For financial liabilities there were no changes to classification and measurement except for the recognition of changes in own credit risk in other comprehensive income, for liabilities designated at fair value through profit or loss. IFRS 9 relaxes the requirements for hedge effectiveness by replacing the bright line hedge effectiveness tests. It requires an economic relationship between the hedged item and hedging instrument and for the ‘hedged ratio’ to be the same as the one management actually use for risk management purposes. Contemporaneous documentation is still required but is different to that currently prepared under IAS 39. The standard is effective for accounting periods beginning on or after 1 January 2018. Early adoption is permitted. The Company has not early adopted IFRS 9 and has yet to assess IFRS 9’s full impact.
 
There are no other standards which are currently available for early adoption which are expected to have a significant effect on the consolidated financial statements of the Company
 
2.3  Convertible notes
 
Convertible notes that can be converted into share capital at the option of the holder (see note 18) are accounted for as compound financial instruments comprised of the notes and a conversion option. If the number of shares to be issued upon conversion varies with changes in the fair value of the underlying shares, the conversion option is classified as a financial liability. The conversion option is recognized initially at fair value (see note 3.3) and is re-measured at each reporting date with changes recognized in the consolidated statement of comprehensive income. The notes are initially recognized at fair value and are subsequently measured at amortized cost. Any difference between the proceeds of the convertible notes issuance (net of transaction costs) and the redemption value is recognized in the income statement over the term of the notes using the effective interest method. The equity component of a compound financial instrument is initially recognized at fair value and not re-measured subsequent to initial recognition.
 
2.4 Consolidation
 
Subsidiaries are all entities over which the Company has control. The Company controls an entity when the Company is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are de-consolidated from the date that control ceases.
 
Intercompany transactions, balances and unrealized gains on transactions between group companies are eliminated. Unrealized losses are also eliminated. When necessary amounts reported by subsidiaries have been adjusted to conform with the Company’s accounting policies.
 

 
2.5 Foreign currency translation
 
Functional and presentation currency
 
Items included in the financial statements of each of the Company’s entities are measured using the currency of the primary economic environment in which the entity operates (‘the functional currency’). The consolidated financial statements are presented in Euro (‘€’), which is the Company’s functional and presentation currency.
 
Transactions and balances
 
Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions or valuation where items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the income statement.
 
Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the income statement within ‘finance income or cost.’ All other foreign exchange gains and losses are presented in the income statement within ‘other (losses)/gains – net.’
 
2.6 Notes to the cash flow statement
 
The cash flow statement has been prepared using the indirect method. The cash disclosed in the cash flow statement is comprised of cash and cash equivalents. Cash comprises cash on hand and demand deposits. Cash equivalents are short-term, highly liquid investments that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value. Cash flows denominated in foreign currencies have been translated at the average exchange rates. Exchange differences, if any, affecting cash items are shown separately in the cash flow statement. Interest paid and received, dividends received and income tax are included in the cash from operating activities.
 
2.7 Leasehold improvements and equipment
 
Leasehold improvements and equipment comprise mainly leasehold improvements, laboratory equipment and other office equipment. Leasehold improvements and equipment are stated at historical cost less depreciation. Historical cost includes expenditure that is directly attributable to the acquisition of the items.
 
Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset only when it is probable that future economic benefits associated with the item will flow to the Company and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognized. All other repairs and maintenance are charged to the income statement during the financial period in which they are incurred.
 
Depreciation on leasehold improvements and equipment is calculated using the straight-line method to allocate their cost over their estimated useful lives, as follows:
 
Leasehold improvements
5-10 years
Laboratory equipment
3-5 years
Office equipment
3-5 years
 
Leasehold improvements are depreciated over the shorter of the expected lease term for the buildings the assets relate to or the estimated useful life.
 
Tangible fixed assets that are leased under a finance lease are depreciated over the shorter of the lease term or their estimated useful lives unless there is reasonable certainty that the Company will obtain ownership at the end of the lease term, in which case the assets are depreciated over their estimated useful lives.
 

 
The assets’ residual values and useful lives are reviewed, and adjusted if appropriate, at the end of each reporting period.
 
An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater than its estimated recoverable amount (note 2.9). The impairment is recognized through operating income and loss.
 
Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized within other (losses)/gains—net in the income statement.
 
2.8 Intangible assets
 
Intangible assets comprise mainly acquired patents, licenses and software. Intangible assets are initially measured at acquisition cost or production cost, including any directly attributable costs of preparing the asset for its intended use. Amortization begins when an asset is available for use and amortization is calculated using the straight-line method to allocate their cost over their estimated useful lives, as follows:
 
Patents & licenses
10 years or period till patent or license expires
Software
3-5 years
 
The Company only owns intangible assets with finite useful lives.
 
Intangible assets are carried at cost less accumulated amortization and accumulated impairment losses. The useful lives of intangible assets are reviewed at each reporting date. The effect of any adjustment to useful lives is recognized prospectively as a change of accounting estimate.
 
Amortization of intangible assets is recognized on the relevant line of the income statement according to the purpose for which the asset is used.
 
Research and development
 
Research expenses are recognized as expenses when incurred. Costs incurred on development projects are recognized as intangible assets as of the date as of which it can be established that it is probable that future economic benefits attributable to the asset will flow to the Company considering its technological and commercial feasibility. This is generally the case when regulatory approval for commercialization is achieved and costs can be measured reliably. Given the current stage of the development of the Company’s products, no development expenditures have yet been capitalized. Intellectual property-related costs for patents are part of the expenditure for the research and development projects. Therefore, registration costs for patents are expensed when incurred as long as the research and development project concerned does not meet the criteria for capitalization.
 
2.9 Impairment of non-financial assets
 
Assets that are subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. An impairment loss is recognized as the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs of disposal and value in use. For the purpose of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). Non-financial assets that were previously impaired are reviewed for possible reversal of the impairment at each reporting date.
 
2.10 Other financial assets
 
Classification
 
The Company classifies its financial assets in the following categories: a) Financial assets at fair value through profit and loss, and b) Loans and receivables.
 

 
The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition.
 
a) Financial assets at fair value through profit and loss
 
Derivative instruments are categorized in this category as the Company currently does not apply hedge accounting (note 2.14). Assets in this category are classified as current assets if expected to be settled within 12 months, otherwise they are classified as non-current.
 
b) Loans and receivables
 
Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for maturities greater than 12 months after the end of the reporting period. These are classified as non-current assets. The Company’s loans and receivables comprise ‘trade and other receivables’ as well as ‘other financial assets’ which relate to lease deposits on the balance sheet.
 
2.11 Recognition and measurement
 
Regular purchases and sales of financial assets are recognized on the trade-date—the date on which the Company commits to purchase or sell the asset. Financial assets carried at fair value through profit or loss are initially recognized at fair value, and transaction costs are expensed in the income statement. Financial assets at fair value through profit or loss are subsequently carried at fair value. Loans and receivables are subsequently carried at amortized cost using the effective interest method. Financial assets are derecognized when the rights to receive cash flows from the investments have expired or have been transferred and the Company has transferred substantially all risks and rewards of ownership.
 
Gains or losses arising from changes in the fair value of the ‘financial assets at fair value through profit or loss’ category are presented in the income statement within finance income-net -in the period in which they arise.
 
2.12 Offsetting financial instruments
 
Financial assets and liabilities are offset and the net amount reported in the balance sheet when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis, or realize the asset and settle the liability simultaneously. The legally enforceable right must not be contingent on future events and must be enforceable in the normal course of business and in the event of default, insolvency or bankruptcy of the company or the counterparty.
 
2.13 Impairment of financial assets
 
Loans and receivables
 
The Company assesses at the end of each reporting period whether there is objective evidence that a financial asset or group of financial assets is impaired. Impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a loss event) and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated.
 
The criteria the Company uses to determine if there is objective evidence of an impairment loss include:
 
·
significant financial difficulty of the obligor;
 
·
a breach of contract, such as a default or delinquency in payments;
 
·
the Company, for economic or legal reasons relating to the counterparty’s financial difficulty, granting to the counterparty a concession that the Company would not otherwise consider; or
 
·
it becomes probable that the counterparty will enter bankruptcy or other financial reorganization.
 

 
The amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate. The carrying amount of the asset is reduced directly. The amount of the loss is recognized in the consolidated income statement.
 
If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the reversal of the previously recognized impairment loss is recognized in the consolidated income statement.
 
2.14 Derivative financial instruments and hedging activities
 
Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value. The resulting gain or loss is recognized in the consolidated income statement as the Company currently does not apply hedge accounting.
 
2.15 Inventories
 
Inventories are stated at the lower of cost and net realizable value. Cost is determined using the first-in, first-out (FIFO) method. The cost of finished goods and work in progress comprises manufacturing design and validation costs, raw materials, direct labor, other direct costs and related production overheads (based on normal operating capacity). It excludes borrowing costs. Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses.
 
All inventories are used in research and development activities and have no alternative use, consequently they are valued at nil due to the uncertainty that future economic benefits will flow to the Company from their use.
 
2.16 Trade receivables
 
Trade receivables are amounts due from customers for license fee payments or services performed in the ordinary course of business. If collection is expected in one year or less (or in the normal operating cycle of the business if longer), they are classified as current assets. Trade receivables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less provision for impairment, if any.
 
2.17 Cash and cash equivalents
 
Cash and cash equivalents include cash on hand, deposits held at call with banks and current accounts with banks. Cash equivalents are short-term, liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value. Cash balances which are not freely available for use are classified as restricted cash as a component of other financial assets (note 11).
 
2.18 Equity
 
The Company classifies an instrument, or its component parts, on initial recognition as a financial liability or an equity instrument in accordance with the substance of the contractual arrangement and the definitions of a financial liability and an equity instrument.
 
An instrument is classified as a financial liability when it is either (i) a contractual obligation to deliver cash or another financial asset to another entity or to exchange financial assets or financial liabilities with another entity under conditions that are potentially unfavorable to the Company; or (ii) a contract that will or may be settled in the Company’s own equity instruments and is a non-derivative for which the Company is or may be obliged to deliver a variable number of the Company’s own equity instruments or a derivative that will or may be settled other than by the exchange of a fixed amount of cash or another financial asset for a fixed number of the Company’s own equity instruments.
 

 
An equity instrument is defined as any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. An instrument is an equity instrument only if the issuer has an unconditional right to avoid settlement in cash or another financial asset.
 
Ordinary shares
 
Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or options are shown in equity as a deduction from the proceeds, net of tax.
 
Preference shares
 
A financial instrument or its component parts are classified on initial recognition as a financial liability or a financial asset or an equity instrument in accordance with the substance of the contractual arrangement and the definitions of a financial liability or a financial asset and an equity instrument.
 
In previous years the Company issued three classes of preference shares, Class A, Class B and Class O shares.
 
a) Class A and Class B preference shares
 
Class A and Class B shares had a dividend preference over ordinary shares and Class O shares. In addition Class A and Class B shares had an anti-dilution protection that is not applicable for Class O and ordinary Shares. The anti-dilution protection was under the full control of the Company and did not affect the equity classification of the Class A and Class B shares.
 
Dividends paid on the preference shares were treated as profit appropriation.
 
b) Class O preference shares
 
Class O shares had a dividend preference over ordinary shares. Class O shares qualified as equity.
 
Pursuant to the Shareholders’ Agreement all of the outstanding preferred shares converted into ordinary shares upon the consummation of the IPO with a conversion rate of one-to-one.
 
2.19 Trade and other payables
 
Trade payables are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Accounts payable are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the business if longer). If not, they are presented as non-current liabilities.
 
Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method.
 
Other payables include accruals for employee and other operating costs incurred in the ordinary course of business. Other payables are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the business if longer).
 
2.20 Borrowings
 
Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently carried at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the income statement over the period of the borrowings using the effective interest method. Borrowings (and financial liabilities in general) are derecognized when the Company’s contractual obligations are discharged, they cancel or expire.
 
The Company has obtained loans from various governmental and non-profit groups. To encourage research and development, the Company obtained certain loans that generally bear an interest rate below the

 
market interest rate, considered by the Company to be 12% over the last five years. The difference between fair value of the loans and the notional amount of the loans at inception is treated as a donation received for certain research performed by the Company and is deferred and recognized as Other income during the periods during which expenses are incurred.

Certain loans from patient organizations have no fixed redemption schemes and repayment is due when certain pre-determined milestones are met. A change in estimate on the redemption date has an impact on the borrowing value at each subsequent balance sheet date. The borrowing value at a certain date equals the discounted value of the redemption using the effective interest rate. The impact of the change in estimate is reflected as financial expenses.
 
2.21 Current and deferred income tax
 
The tax expense for the period comprises current and deferred tax. Tax effects are recognized in the income statement, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case the tax is also recognized in other comprehensive income or directly in equity, respectively.
 
The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the balance sheet date in the countries where the Company’s subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.
 
Deferred income tax is recognized, using the liability method, on temporary differences arising between the tax basis of assets and liabilities and their carrying amounts in the consolidated financial statements. However, the deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit and loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantially enacted by the balance sheet date and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled.
 
Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized.
 
Deferred income tax is provided on temporary differences arising on investments in, except where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future.
 
Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income taxes assets and liabilities relate to income taxes levied by the same taxation authority on either the taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.
 
2.22 Employee benefits
 
(a) Pension obligations
 
The Company operates a defined contribution pension plan for all employees funded through payments to an insurance company. The Company has no legal or constructive obligations to pay further contributions if the fund does not hold sufficient assets to pay all employees the benefits relating to employee service in the current and prior periods. The contributions are recognized as employee benefit expense when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.
 

 
(b) Termination benefits
 
Termination benefits are payable when employment is terminated by the Company before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Company recognizes termination benefits when it is demonstrably committed to either: terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal; or providing termination benefits as a result of an offer made to encourage voluntary redundancy. Benefits falling due more than 12 months after the end of the reporting period are discounted to their present value.
 
(c) Bonus plans
 
The Company recognizes a liability and an expense for bonus plans if contractually obliged or if there is a past practice that has created a constructive obligation.
 
2.23 Share-based payments
 
The Company operates equity-settled share-based compensation plans, under which it receives services from managing directors, supervisory directors and selected employees as consideration for equity instruments (options or restricted shares) of the Company. The fair value of these equity instruments granted in exchange for the employee services received is recognized as an expense against a credit in equity. The total amount to be expensed is determined by reference to the grant date fair value of the equity instruments granted:
 
·
including any market performance conditions;
 
·
excluding the impact of any service and non-market performance vesting conditions; and
 
·
including the impact of any non-vesting conditions.
 
Vesting conditions are included in assumptions about the number of equity instruments that are expected to vest. The total expense is recognized over the vesting period, which is the period over which all of the specified vesting conditions are to be satisfied. At the end of each reporting period, the Company revises its estimates of the number of equity instruments that are expected to vest based on the non-market vesting conditions. It recognizes the impact of the revision to previous estimates, if any, in the income statement, with a corresponding adjustment to equity.
 
If the terms of an equity-settled award are modified at a minimum an expense is recognized as if the terms had not been modified. An additional expense is recognized for any modification that increases the total fair value of the share-based payment arrangement or is otherwise beneficial to the employee as measured at the date of modification.
 
Where the Company is receiving employee services in a share-based payment transaction settled by a shareholder, it measures the services received as an equity-settled share-based payment transaction. The fair value of employee services received, measured by reference to the grant date fair value, is recognized over the vesting period with a corresponding adjustment to equity.
 
In 2012 the Company granted equity-settled options to members of the Management Board, subject to vesting only upon a liquidity event such as a change of control of the Company or an IPO and are further subject to continued employment conditions until the date such an event occurs. The number of options that vest will depend on the share price development following the IPO. This market performance condition is included in the fair value of the options granted.
 
As from the date such a liquidity event is deemed to be probable, the fair value is recognized as an expense over the estimated vesting period, taking into account the services received during the period from the grant date.
 
The Company’s share-based compensation plans qualify as equity-settled share-based payment transactions. When the options are exercised, the Company issues new shares. The proceeds received net of
 

 
any directly attributable transaction costs are credited to share capital (nominal value) and share premium when the options are exercised.
 
The social security contributions payable by the Company in connection with the vesting of the share options or restricted shares is considered an integral part of the grant itself, and the charge will be treated as a cash-settled transaction. Normally, the maximum social security charge of an employee that receives option grants is already met and no additional social security charges are due.
 
2.24 Revenue recognition
 
Revenue comprises the fair value of the consideration received or receivable for the sale of licenses and services in the ordinary course of the Company’s activities. Revenue is shown net of value-added tax, returns, rebates and discounts and after eliminating sales within the Company.
 
The Company recognizes revenue when the amount of revenue can be reliably measured, it is probable that future economic benefits will flow to the entity and when specific criteria have been met for each of the Company’s activities as described below. The Company bases its estimates on historical results, taking into consideration the type of customer, the type of transaction and the specifics of each arrangement.
 
License revenue
 
License revenue can comprise upfront payments and milestone payments.
 
a) Upfront payments
 
Non-refundable upfront licensing fees and certain guaranteed, time-based payments that require continuing involvement in the form of research and development, manufacturing or other efforts by the Company are recognized in the period of the expected performance.
 
Upon signing of the Research & Development and Collaboration & License agreement with GlaxoSmithKline (“GSK”) the Company received €17.2 million (£16.0 million) as a non-refundable upfront payment. The expected performance was deemed to occur on a straight line basis over a 5 year period. The Company was obliged, until the termination of the agreement in January 2014, to provide research and development services regarding certain pre-defined programs in the agreement. Other upfront payments received from GSK have been recognized by reference to the stage of completion of the underlying agreement at the balance sheet date (also referred to as percentage of completion method) whenever the rendering of services under a license revenue agreement could be estimated reliably.
 
The rendering of services can be estimated reliably when, in addition to general conditions mentioned further above, the following conditions are met:
 
·
stage of completion of the transaction at the balance sheet date can be measured reliably; and
 
·
costs incurred for the transaction and the costs to complete the transaction can be measured reliably.
 
When the above criteria are not met, revenue arising from the rendering of services is recognized only to the extent of the expenses recognized that are recoverable (cost-recovery approach). Costs under these types of arrangements are expensed as incurred and therefore the pattern of cost recognition may be different than revenue recognition.
 
b) Milestone payments
 
Milestone payments are contingent upon the achievement of contractually stipulated targets. The achievement of these milestones depended largely on meeting specific requirements laid out in the GSK collaboration agreement, so the related revenue was only recognized once substantive services had been performed in relation to the payment and contractual milestones had been fully achieved and confirmed by the counterparty (note 19).
 

 
Collaboration revenue
 
Collaboration revenue from contracts, typically from delivering research and development services, which may or may not be related to a licensing agreement, is recognized on the basis of labor hours delivered at the contractual full time employee rates.
 
Cost reimbursements to which the Company is entitled to under certain agreements are recognized in the income statement in the same period of the recorded cost they intend to compensate. When the reimbursable costs are not yet invoiced these amounts are included as a component of trade and other receivables on the balance sheet.
 
Interest income
 
Interest income is recognized using the effective interest method. When a loan and receivable is impaired, the Company reduces the carrying amount to its recoverable amount, being the estimated future cash flow discounted at the original effective interest rate of the instrument, and continues unwinding the discount as interest income. Interest income on impaired loan and receivables are recognized using the original effective interest rate.
 
2.25 Government grants
 
The Company receives certain government grants, which support its research effort in defined projects. These grants generally provide for reimbursement of approved costs incurred as defined in the respective grants. Income in respect of grants also includes contributions towards the costs of research and development. Income is recognized when costs under each grant are incurred in accordance with the terms and conditions of the grant and the collectability of the receivable is reasonably assured.
 
Government grants relating to costs are deferred and recognized in the income statement over the period necessary to match them with the costs they are intended to compensate. When the cash in relation to recognized government grants is not yet received the amount is included as a receivable on the balance sheet.
 
The Company recognizes income from government grants under ‘Other income’ in the income statement.
 
2.26 Recognition research and development expenses
 
Research expenditures are recognized as expenses when incurred except when certain criteria for capitalization as intangible assets are met (note 2.8). At each balance sheet date, the Company estimates the level of service performed by the vendors and the associated cost incurred for the services performed.
 
2.27 Leases
 
Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are charged to the income statement on a straight-line basis over the period of the lease.
 
The Company leases certain laboratory equipment and office equipment. Leases for leasehold improvements and equipment where the Company bears substantially all the risks and rewards of ownership are classified as finance leases. Finance leases are capitalized at the lease’s commencement at the lower of the fair value of the leased property or the present value of the minimum lease payments.
 
Each finance lease payment is allocated between the liability and finance charges in order to achieve a constant rate on the finance balance outstanding. The finance balances, net of finance charges, are included in other long-term payables. The interest element of the finance cost is charged to the income statement over the lease period to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The laboratory and office equipment acquired under finance leases are depreciated over the shorter of the useful life of the asset or the lease term.
 
2.28 Dividend distribution
 

 
Dividend distribution to the Company’s shareholders shall be recognized as a liability in the Company’s financial statements in the period in which the dividends are approved by the Company’s shareholders.
 
3. Financial risk management
 
3.1 Financial risk factors
 
The Company’s activities expose it to a variety of financial risks: market risk (including currency risk, fair value interest rate risk, cash flow interest rate risk and price risk), credit risk and liquidity risk. The Company’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Company’s financial performance. The Company uses derivative financial instruments on a limited scale to hedge certain risk exposures. No hedge accounting is applied.
 
Risk management is carried out by the financial management of the Company. The financial management identifies, evaluates and hedges financial risks in close co-operation with the Company’s operating units. There have been no changes in the financial management team that is responsible for financial risk management or in the Company’s financial risk management policies since December 31, 2013.
 
Market risk
 
a) Foreign exchange risk
 
The Company operates internationally and is exposed to foreign exchange risk arising from various currency exposures, primarily with respect to the British pound and the U.S. Dollar as the Company receives payments from its main business partner GSK in British pounds and acquires materials produced according to good manufacturing practice for medicinal products (’GMP materials’) in US dollars. From these future commercial transactions foreign exchange risk arises. The exposure to British pounds is expected to be lower in future periods as a result of the termination of the GSK collaboration agreement. No formal policy has been set up to manage the foreign exchange risk against the functional currency of the Company.
 
At December 31, 2014 there was a net amount of trade receivables in British pounds of €1.3 million (2013: €3.1 million; 2012: €0.6 million) and a net liability in U.S. Dollars of €12.5 million (2013: €0.4 million 2012: €0.2 million). Foreign currency denominated trade receivables and trade payables are short term in nature (generally 30 to 45 days). As a result foreign exchange rate movements during the years presented had an immaterial effect on the financial statements.
 
b) Price risk
 
The market prices for the production of preclinical and clinical compounds and drug substances as well as external contracted research may vary over time. Currently commercial product prices of the development products are uncertain. When the development products near the regulatory approval date or potential regulatory approval date, the uncertainty of the potential sales price decreases. The Company is not exposed to commodity price risk.
 
Furthermore the Company does not hold investments classified as available-for-sale or at fair value through profit or loss, therefore are not exposed to equity securities price risk.
 
c) Cash flow and fair value interest rate risk
 
The Company’s interest rate risk arises from long-term borrowings. Borrowings issued at variable rates expose the Company to cash flow interest rate risk, which is partially offset by cash held at variable rates. Borrowings issued at fixed rates expose the Company to fair value interest rate risk. During 2014, 2013 and 2012, the Company’s borrowings were mainly denominated in Euro’s.
 
The Company manages its cash flow interest rate risk by using floating-to-fixed interest rate swaps. Such interest rate swaps have the economic effect of converting borrowings from floating rates to fixed rates.
 
The Company does not enter into fixed-to-floating interest rate swaps.
 

 
At December 31, 2014 if interest rates on borrowings had been 0.1% higher/lower with all other variables held constant, post-tax results for the year would have been €49 thousand (2013: €8 thousand 2012: €6 thousand) lower/higher as a result of changes in the fair value of the borrowings. The effect of a change in interest rates of 0.1% on borrowings would have had an insignificant effect on post-tax results for the year as a result of changes in the fair value of the floating to fixed interest rate swap.
 
Credit risk
 
Credit risk is managed on a Company basis. Credit risk arises from cash and cash equivalents as well as credit exposures to external parties, including amounts to be invoiced and outstanding receivables. For banks and financial institutions, only independently rated parties with a minimum rating of ‘A’ are accepted at the beginning of the fixed interest term.
 
The Company does business with a limited group of external parties.
 
If external parties are independently rated, these ratings are used. If there is no independent rating, the credit quality of these parties is assessed, taking into account its financial position, past experience and other factors.
 
No credit limits were exceeded during the reporting period, and management does not expect any losses from non-performance by counterparties.
 
Liquidity risk
 
Management forecasts the Company’s liquidity requirements to ensure it has sufficient cash to meet operational needs. Such forecasting takes into consideration the Company’s financing plans and expected cash flow.
 
As of December 31, 2014 the Company had cash and cash equivalents of €90.7 million.
 
The table below analyses the Company’s financial liabilities into relevant maturity groupings based on the remaining period at the balance sheet date to the contractual maturity date. Derivative financial liabilities are included in the analysis if their contractual maturities are essential for an understanding of the timing of the cash flows. The amounts disclosed in the table are the contractual undiscounted cash flows.

From inception until December 31, 2014 the Company received €7.1 million in loans from patient organizations and government agencies. Most loans have fixed redemption criteria and repayment is due
 

 
when certain pre-determined milestones have been met. The Company will reach these milestones on the successful commercialization of corresponding pipeline products.
 
3.2 Capital risk management
 
Until February 12, 2015, the Company’s objectives when managing capital were to safeguard the Company’s ability to continue as a going concern in order to provide returns for shareholders, benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital. The total amount of equity as recorded on the balance sheet was seen and managed as capital by the Company.
 
3.3 Fair value estimation
 
For financial instruments that are measured in the balance sheet at fair value, IFRS 13 requires disclosure of fair value measurements by level of the following fair value measurement hierarchy:
 
·
Quoted prices (unadjusted) in active markets for identical assets or liabilities (level 1);
 
·
Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices) (level 2);
 
·
Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs) (level 3).
 
The fair value of the conversion option in the convertible notes issued to an affiliate of CureDuchenne (see note 18) upon initial recognition on September 22, 2014 and as of December 31, 2014 has been determined using a decision tree/cumulative probabilities option pricing model. Key inputs to the option pricing model included Level 2 and Level 3 fair value hierarchy inputs and the fair value of the option is classified as Level 3. Assumptions are made on relevant factors such as the investor's conversion strategy and the timing of a qualified financing in order to determine the fair value of the conversion feature. A 10% change in the probability assigned to the investor’s conversion strategy would increase the fair value of the option by a maximum of €23 thousand. A delay of one year in the Company’s assumed timing of a qualified financing would decrease the fair value of the conversion option by €11 thousand. Changes in fair value are analyzed by the Company at each reporting date. The fair value of the CureDuchenne conversion option embedded derivative upon inception amounted €62 thousand. As of December 31, 2014, the fair value of the derivative was nil. As of December 31, 2014 the change in fair value of the CureDuchenne notes conversion option was €62 thousand and it was recognized as unrealized gain within finance income in the consolidated statement of comprehensive income.
 
The fair value of the conversion option in the convertible loan from BioMarin (see note 18) upon initial recognition on November 26, 2014 and as of December 31, 2014 has been determined using an option pricing model. Key inputs to the option pricing model included Level 2 and Level 3 fair value hierarchy inputs and the fair value of the option is classified as Level 3. Assumptions were made as to the probability of the loan being converted. The effect of a 1% increase in the probability assigned to the conversion would increase the fair value of the conversion feature by approximately €300 thousand.
 
The Company’s other financial assets and liabilities that are measured at fair value at December 31, 2014 and 2013 are all measured as level 2 financial instruments.
 
As of December 31, 2014, 2013 and 2012 financial instruments carried at fair value through profit and loss amounted to €65 thousand (2013: €30 thousand; 2012: €48 thousand).
 
The fair value of financial instruments that are not traded in an active market (for example, over-the-counter derivatives) is determined by using valuation techniques. These valuation techniques maximize the use of observable market data where it is available and rely as little as possible on entity specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2.
 
If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3.
 

 
The carrying amount of all financial assets and financial liabilities is a reasonable approximation of the fair value and therefore information about the fair values of each class has not been disclosed.
 
4. Critical accounting estimates and judgments
 
Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.
 
4.1 Critical accounting estimates and assumptions
 
The preparation of financial statements in conformity with IFRS requires the Company to make estimates and assumptions that affect the reported amounts and classifications of assets and liabilities, revenues and expenses in the consolidated financial statements. The estimates that have a significant risk of causing a material adjustment to the financial statements are as follows. Actual results could differ materially from those estimates and assumptions.
 
Share-based payments
 
The Company operates equity-settled share based compensation plans, pursuant to which certain participants are granted the right to acquire equity instruments (option or restricted shares) of the Company. The plans are accounted for in accordance with the policy as stated in note 2.23. The total amount to be expensed is determined by reference to the fair value of the options granted. The fair value of grants made under the Employee Share Option Plan is measured at the date of grant using accepted option valuation methods (note 16).
 
Income taxes
 
The Company is subject to income taxes in the Netherlands and the United States. Significant judgment is required in determining the use of net operating loss carry forwards and taxation of upfront and milestone payments for income tax purposes. There are many transactions and calculations for which the ultimate tax determination is uncertain. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the current and deferred income tax assets and liabilities in the period in which such determination is made.
 
Research and development expenditures
 
Research expenditures are currently not capitalized but are reflected in the income statement because the criteria for capitalization are not met (note 4.2). At each balance sheet date, the Company estimates the level of service performed by the vendors and the associated costs incurred for the services performed.
 
Although we do not expect the estimates to be materially different from amounts actually incurred, the understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in reporting amounts that are too high or too low in any particular period.
 
Borrowings
 
Certain loans from patient organizations have no fixed redemption schemes and repayment is due when certain pre-determined milestones are met. As of December 31, 2014 the Company recorded €7.8 million of such loans with no fixed redemption schemes.
 
Significant judgment is required in determining when the Company will achieve these pre-determined milestones and these judgments may vary over time. A change in the estimate on the redemption date has an impact on the borrowing value at the balance sheet date. As of December 31, 2014 the maturity dates of the borrowings have been assessed resulting in no material changes to the maturity dates. The effect of a one year delay in the redemption dates of these loans would decrease the Company’s borrowing balance by €1 million as of December 31, 2014. The borrowing value at a certain date equals the discounted value of the redemption using the effective interest rate.
 

 
Certain loans from patient organizations bear an interest rate below the market interest rate, considered by the Company to be 12% over the last five years. The difference between fair value of the loans and the notional amount of the loans at inception is treated as a donation received for certain research performed by the Company and is deferred and recognized as Other income during the periods during which expenses are incurred. The estimation of the market rate includes a certain amount of judgment. Pre-commercial financing of a biotech company has a high risk profile and might be assessed differently by each individual institution. The fair value of the loans from patient organizations approximates their carrying amount. A 100 basis points increase in the estimated market interest rate would decrease the fair value of the total borrowings as of December 31, 2014 by approximately €0.1 million.

As of December 31, 2014, the Company had issued notes convertible into the Company’s shares. The fair value of the conversion option of those notes has been determined using option pricing models with key inputs classified as Level 3 in the fair value hierarchy. The Company has made assumptions on relevant factors such as the investor's conversion strategy or the probability of the notes being converted. As of December 31, 2014, none of the notes had been converted.

Intangible assets
 
As of December 31, 2014, we recorded patents and licenses with a net book value of €0.4 million. As of December 31, 2014, there were no changes to management’s assumptions used to determine the patent and licenses’ recoverable amount, which exceeds the carrying value of €0.4 million, and therefore no impairment is required.
 
Deferred revenue/income & License income
 
Upfront license fee payments received under the research and collaboration agreement with GSK were initially deferred and recognized based on the percentage of completion method, which required the Company to estimate the work performed to date as a proportion of the total work expected to be performed.
 
As a result of the termination of the research and collaboration agreement, the Company was released from any performance obligations and recorded €14.7 million license revenue in the first quarter of 2014.

As of December 31, 2014, the Company’s deferred income balance totals €0.6 million of grants deferred (reference is made to note 19).

4.2 Critical judgments in applying the entity’s accounting policies
 
The preparation of financial statements in conformity with IFRS also requires the Company to exercise judgment in applying the accounting policies. Critical judgments in the application of the Company’s accounting policies relate to income taxes, research and development expenditures, revenue and the cost of license revenue and other income.
 
Income taxes
 
The Dutch corporate income tax act provides for the possibility of a consolidated tax regime, referred to as a fiscal unity. A fiscal unity is a combination of a parent and subsidiaries whereby formally the parent, Prosensa Holding N.V., is the entity that is taxed for the consolidated profits of the fiscal unity.
 
The Company, which has a history of recent tax losses, recognizes deferred tax assets arising from unused tax losses or tax credits only to the extent the relevant fiscal unity has sufficient taxable temporary differences or there is convincing other evidence that sufficient taxable profit will be available against which the unused tax losses or unused tax credits can be utilized by the fiscal unity. Management’s judgment is that sufficient convincing other evidence is not available and a deferred tax asset is therefore not recognized.
 

 
Research and development expenditures
 
The project stage forms the basis for the decision whether costs incurred for the Company’s research and development projects can be capitalized or not. In general, the Company’s vision is that clinical development expenditures are not capitalized until the Company files for regulatory approval (i.e. approval to commercially use the product; for example the filing for final FDA approval in the United States or filing for market authorization with the EMA in the EU), as this is considered to be essentially the first point in time where it becomes probable that future revenues can be generated and the project becomes commercially successful.
 
As of each balance sheet date, the Company estimates the level of service performed by the vendors and the associated costs incurred for the services performed. As part of the process of preparing the Company’s financial statements the Company is required to estimate its accrued expenses. This process involves reviewing quotations and contracts, identifying services that have been performed on the Company’s behalf, estimating the level of service performed and the associated cost incurred for the service when it has not yet been invoiced or otherwise notified of the actual cost. The majority of the Company’s service providers invoice it monthly in arrears for services performed or when contractual milestones are met. The Company makes estimates of its accrued expenses as of each balance sheet date in its financial statements based on facts and circumstances known to it at that time. The Company periodically confirms the accuracy of its estimates with the service providers and makes adjustments if necessary. The significant estimates in its accrued research and development expenses are related to fees paid to clinical research organizations, or CROs, in connection with research and development activities for which the Company has not yet been invoiced. The Company bases its expenses related to CROs on its estimates of the services received and efforts expended pursuant to quotes and contracts with CROs that conduct research and development on its behalf.
 
The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to vendors will exceed the level of services provided and result in a prepayment of the research and development expense. In accruing service fees, the Company estimates the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the Company’s estimate, it adjusts the accrual or prepayment expense accordingly. Although the Company does not expect its estimates to be materially different from amounts actually incurred, its understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in reporting amounts that are too high or too low in any particular period.
 
Revenue and cost of license revenue
 
In October 2009 the Company signed a Research & Development and Collaboration & License agreement with GSK. Upon signing of the agreement the Company received €17.2 million (£ 16.0 million) as a non-refundable upfront payment. Until the termination of the agreement effective on January 12, 2014, the Company had continuing performance obligations and revenues related to the license fee payments were deferred and the related revenues were recognized in the period of the expected performance. The Company made the assumption that the expected performance occurred on a straight line basis over the 5 year period the Company was deemed obliged to provide research and development services regarding certain pre-defined programs in the agreement.
 
Other upfront license fee payments are deferred and revenue is recognized based on the percentage of completion method. Use of the percentage of completion method requires the Company to estimate the work performed to date as a proportion of the total work to be performed.
 
The related cost of license revenue is based on the determination of net license revenue as defined in our license agreements after deducting allocable expenses and is subject to a certain amount of judgment.
 
Other income
 

 
The Company is part of two pan-European consortia, each of which has been awarded a Framework Programme 7 (“FP7”) research grant of €6 million from the European Commission to support respectively ongoing clinical study PRO045 and a separate collaborative bioimaging project to support our PRO053 and Natural History programs. We have also received governmental research subsidies. Grant proceeds are deferred and other income is recognized based on the percentage of completion method.
 
To encourage research and development the Company obtained certain loans that generally bear interest at a rate below the market interest rate, considered by the Company to be 12% over the last five years. The difference between fair value of the loans and the notional amount of the loans at inception is treated as a donation received for certain research performed by the Company and recognized in Other income over the periods during which expenses are incurred. Certain loans have no fixed redemption schemes and repayment is due when certain predetermined milestones are met. The fair value at inception is based on the initial estimation of when the milestones will be met, which requires a certain amount of judgment.
 
5. Segment information
 
The Company operates in one reportable segment, which comprises the discovery and development of innovative, RNA-based therapeutics. The Management Board is identified as the chief operating decision maker. The Management Board reviews the consolidated operating results regularly to make decisions about resources and to assess overall performance.
 
Until February 12, 2015, the non-current assets of the Company were located in the Company’s country of domicile. The Company derived its revenues from a single party, GSK, under the research and collaboration agreement, an exclusive worldwide collaboration for the development and commercialization of RNA-based therapeutics for DMD. The agreement was terminated effective January 12, 2014.

The par value as of December 31, 2014 is €0.01 per share (as of December 31, 2013 and 2012: €0.01 per share). All issued shares are fully paid. Besides the minimum amount of share capital to be held under Dutch law, there are no distribution restrictions applicable to equity of the Company.
 
During 2014, the Company issued 208,587 ordinary shares as a result of exercises in the Company’s share-based compensation plan. On July 3, 2013 the Company issued 6,900,000 ordinary shares at an initial public offering price of $13.00 per share. For the issuance of the 6,900,000 ordinary shares, the Company received proceeds, after deducting underwriting discounts but prior to deducting offering expenses payable by the Company, of €64.0 million ($83.4 million).
 
Offering expenses that were deducted from the share proceeds totaled €854 thousand. The Management Board determined that May 24, 2013, the date Prosensa publicly filed its offering prospectus with the Securities and Exchange Commission, was considered to be the date at which the IPO became probable. Expenses related to the IPO incurred subsequent to May 24, 2013 were deducted from the proceeds of the share issue.
 
As of December 31, 2014 and 2013, our authorized share capital is €1,750,114.90, divided into 87,505,745 ordinary shares, each with a par value of €0.01 and 87,505,745 cumulative preferred shares, each with a par value of €0.01. All issued shares are fully paid.
 
The Company has adopted an anti-takeover measure pursuant to which the Management Board may, subject to Supervisory Board approval but without shareholder approval, issue (or grant the right to acquire) cumulative preferred shares. The Company may issue an amount of cumulative preferred shares up to 100% of our issued capital immediately prior to the issuance of such preferred shares. In such event, the cumulative preferred shares will be issued to a separate foundation to be established for this purpose.

The Company has adopted a share-based compensation plan, pursuant to which the Company’s directors and selected employees are granted the right to acquire ordinary shares of the Company (option shares) (note 16). The share-based payment expenses are recorded in the income statement. The share based compensation plan is equity-settled. In case of an equity settled plan, there is no obligation to transfer economic benefits, therefore the credit entry should be recognized as an increase in equity. The Company uses Other reserves as the equity classification.
 
The Company recognized an amount of €311 thousand in Other reserves in relation to the equity component of a convertible promissory note (see note 18).
 
Foundation Prosensa Trust Office (Stichting Administratiekantoor Prosensa Holding B.V.)
 
The Foundation Prosensa Trust Office (‘Stichting Administratiekantoor Prosensa Holding B.V.’ or ‘foundation’) was a trust office with a board independent of the Company.
 
Prior to the IPO, upon the exercise or award or vesting of a non-cash-settled award under the plans, ordinary shares were issued to the foundation, whose purpose was to facilitate administration of options and pool the voting interests of the underlying shares. Post IPO, ordinary shares are directly issued upon the exercise or award or vesting of a non-cash-settled award under the plans instead of depository receipts. After the completion of the transfers of the ordinary shares held by the foundation to the respective depository receipt holders, the foundation was dissolved during 2014.
 
16. Share-based payments
 
Employee stock options
 
The Company has adopted share-based compensation plans, pursuant to which certain participants are granted the right to acquire ordinary shares of the Company (option shares). The share-based compensation plans are equity-settled. Upon the exercise or award or vesting of a non-cash-settled award under the plans, the Company issues ordinary shares.
 
Following the public offer of BioMarin of 100% of the Company’s outstanding stock, all granted options and share-based payments would automatically vest at the date of the transaction. On January 15, 2015, BioMarin announced that the transaction was completed and subsequently all share awards fully vested and they were settled in cash. At December 31, 2014, the Company revised its estimate of the number of equity instruments that are expected to vest and accelerated the vesting period in light of the transaction with BioMarin. The fair value of the awards has been measured using the Black-Scholes formula. The accelerated vesting of the awards resulted in a share-based compensation expense of €3.5 million for the year ended December 31, 2014. For details of employee benefit expenses, see Note 24.
 
Prior to our IPO, participants were not granted the right to acquire ordinary shares but (non-voting) depository receipts (“Depositary Receipts”) in respect of our ordinary shares. Upon the exercise or award or vesting of a non-cash-settled award under the plans, ordinary shares were issued to a Dutch foundation called Stichting Administratiekantoor Prosensa Holding (the “Foundation”), whose purpose was to facilitate administration of options and pool the voting interests of the underlying shares. The Foundation thereupon granted a Depository Receipt for each issued ordinary share to the person entitled to such ordinary share under an award. Legal title to the shares issued under the share-based compensation plan was held by the

 
Foundation, and the voting rights attached to the shares were exercised by the Foundation at its own discretion.

On October 10, 2013 the board of the Foundation resolved to terminate the administration of the ordinary shares and to transfer the ordinary shares to the respective Depository Receipt holder. After the completion of the transfers, the Foundation was dissolved. Going forward, participants will receive ordinary shares upon the exercise or award or vesting of a non-cash-settled award under the plans instead of depository receipts.
 
Options are generally conditional on the employee completing a four year period of service (the vesting conditions). Each such option award vests based on the following schedule: (a) 25% on the first anniversary of the date of the grant, provided that on that date the relevant participant is still employed by the Company, and (b) the remaining 75% in 36 equal monthly installments over a three year period following the first anniversary of the date of grant subject to continued employment of the relevant participant. Due to the BioMarin acquisition, the Company decided to accelerate the vesting of the options as a result of a change of control.

On December 5, 2012 the Company granted to the members of the Management Board 1.0 million options that vest only upon a liquidity event such as a change of control of the Company or an IPO, subject to the continued employment of the member of the Management Board. Following our IPO, the maximum number of options eligible to vest was automatically reduced from 1.0 million to 800,000. In order for any options to become subject to vesting the sustained closing market price for the ordinary shares during any 20 consecutive trading days outside a lock-up or blackout period must exceed a threshold share price. The number of options subject to vesting increases between the threshold share price and the share price entitling the participant to exercise the maximum number of options. Upon each subsequent achievement of a sustained, higher closing market price or level of proceeds from a liquidity event, an additional number of options will become subject to vesting. Each option grant subject to vesting following our IPO will vest and become exercisable based on the following schedule: 25% of the options subject to vesting will vest the day immediately following attainment of such pricing levels (the initial vesting date), and an additional 2.083% will vest at the end of each successive one month period following the initial vesting date, subject to the continued employment of the relevant member of the management board.
 
Unless forfeited or exercised on an earlier date the options expire 10 years after the grant date.

Valuation of ordinary shares
 
The methodology we used prior to our IPO in measuring share-based compensation expense is described below. After our IPO, the fair value of the ordinary shares is based on their quoted market price.
 
Prior to our IPO the fair value of the ordinary shares was determined by the Management Board and Supervisory Board, and took into account the most recently available valuation of ordinary shares performed by an independent valuation firm and the assessment of additional objective and subjective factors the Company believed are relevant and which may have changed from the date of the most recent valuation through the date of the grant.
 
The management board and supervisory board considered numerous objective and subjective factors to determine their best estimate of the fair value of the ordinary shares as of each grant date, including the following:
 
·
the progress of the research and development programs;
 
·
achievement of enterprise milestones, including the entering into collaboration and licensing agreements;
 
·
contemporaneous third-party valuations of the ordinary shares;
 
·
the historical and forecasted performance and operating results;
 
·
the need for future financing to fund operations;
 
·
the rights and preferences of the preferred shares and the preferred shares relative to the ordinary shares;
 
·
the likelihood of achieving a discrete liquidity event, such as a sale of the Company or an initial public offering given prevailing market conditions; and
 
·
external market and economic conditions impacting the industry sector.

In determining the fair values of the ordinary shares as of each award grant date, three generally accepted approaches were considered: income approach, market approach and cost approach. Based on the stage of development and information available, the Company determined that the income approach is the most appropriate method, and when applicable, the Company also employed the prior sale of company stock method to estimate the aggregate enterprise value. In addition, the Company has taken into consideration the guidance prescribed by the American Institute of Certified Public Accounts (AICPA) Audit and Accounting Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation.
 
Discounted cash flow (DCF), a form of the income approach, is an estimate of the present value of the future monetary benefits expected to flow to the owners of a business. It requires a projection of the cash flows that the business is expected to generate. These cash flows are converted to present value by means of discounting, using a rate of return that accounts for the time value of money and the appropriate degree of risks inherent in the business. The discount rate in the DCF analysis is based upon a weighted average cost of capital (WACC) calculated at each valuation date. The WACC is a method that market participants commonly used to price securities and is derived by using the Capital Asset Pricing Model and inputs such as the risk-free rate, beta coefficient, equity risk premiums and the size of the Company.
 

 
The prior sale of Company stock method considers any prior arm’s length sales of the Company’s equity securities. Considerations factored into the analysis include: the type and amount of equity sold, the estimated volatility, the estimated time to liquidity, the relationship of the parties involved, the timing compared to the ordinary shares valuation date and the financial condition and structure of the Company at the time of the sale.
 
The indicated fair value calculated at each valuation date was allocated to the preferred shares and ordinary shares using the option pricing method (OPM), applied retrospectively. The OPM treats ordinary shares and preferred shares as call options on the total equity value of a company, with exercise prices based on the value thresholds at which the allocation among the various holders of a company’s securities changes. Under this method, the ordinary shares have value only if the funds available for distribution to shareholders exceed the value of the liquidation preference at the time of a liquidity event, such as a strategic sale, assuming the enterprise has funds available to make a liquidation preference meaningful and collectible by the holders of preferred shares. The ordinary shares are modeled as a call option on the underlying equity value at a predetermined exercise price. In the model, the exercise price is based on a comparison with the total equity value rather than, as in the case of a regular call option, a comparison with a per share price. Thus, ordinary shares are considered to be a call option with a claim on the enterprise at an exercise price equal to the remaining value immediately after the preferred shares are liquidated. The OPM uses the Black Scholes option-pricing model to price the call options. This model defines the securities’ fair values as functions of the current fair value of a company and uses assumptions such as the anticipated timing of a potential liquidity event and the estimated volatility of the equity securities. Volatility has been estimated based on the observed daily share price returns of peer companies over a historic period equal to the period for which expected volatility is estimated. Volatility is defined as the annualized standard deviation of share price returns. In the allocation of equity, the Company has also considered valuation outcomes of ordinary shares through a sale of the Company versus an IPO and considered the probabilities of each at each valuation date, since the treatment of the liquidation rights is different for these two events. The aggregate value of the ordinary shares is then divided by the number of ordinary shares outstanding to arrive at the per share value.
 
A valuation was performed by an independent valuation firm as of December 2010 and applied to all option grants in 2011. For the grant on March 22, 2011 and the other grants made in September through November, 2011, the Company relied on the December 2010 valuation report, which the Company deemed reasonable based on its progress at that time. Of the total 716,000 options granted in 2011, 707,500 options were granted on March 22, 2011. Between the valuation of our ordinary shares performed as of December 2010 and March 2011, there were no events in our business that were deemed to have an effect on the valuation and thus we believed the December 2010 valuation to continue to be reasonable. Furthermore, there were no significant results in 2011 from any of our development programs including the Phase III-DMD114044 pivotal trial initiated in December 2010, the continuation of the dose escalation study of PRO044 and the preclinical safety studies for PRO045 and PRO053 on-going throughout 2011. Additional valuations were performed by an independent valuation firm as of September 30, 2012 and December 5, 2012 for share-based compensation grants in 2012.
 
The ordinary shares valuation as of December 2010 relied on a DCF to derive the total enterprise value. The cash flow projections were based on probability-weighted scenarios which considered estimates of time to market of the products, market share and pricing. The cash flow projections were estimated over a period equal to the expected product life cycle, and a terminal value period was not applied. All DMD indications in development were included in estimating cash flow projections, most importantly drisapersen. The expected sales were estimated based on a regional level, estimated patient populations and market shares. Production and research and development costs were estimated at the indication level with general and administrative costs and selling and marketing costs assessed at the overall Company level. Cash flow projections also incorporated expected royalties and milestones related to the collaboration agreement with GSK. A WACC of 16.0% was applied. Equity was allocated using the OPM, applied retrospectively, resulting in a determination by the Supervisory Board and the Management Board of a value per ordinary share of €1.00. The OPM relies on the anticipated timing and probability of a liquidity event based on then current plans and estimates of the Supervisory Board and Management Board regarding a liquidity event of 80-85% probability of a sale of the Company and 15-20% probability of an IPO. The Company assumed volatility of 80% based on historical trading volatility for the publicly traded peer companies and a time to liquidity of 1.5 years.
 

 
In December 2010, the Phase III-DMD114044 pivotal trial was initiated by GSK, the completion of this trial was later than anticipated in the projections that were used for the valuation performed in 2010. In 2011 the Company also concluded an amendment to the GSK agreement related to the development terms for PRO044. In this amendment the timing of the milestone payment for GSK licensing PRO044, which had been anticipated in the second quarter of 2011, was restructured, and the anticipated licensing to GSK of PRO044 was deferred significantly. In January 2012, the Company raised total net proceeds of €22.7 million in a private placement of the preferred (Class B) shares. The additional Class B shares were issued on a pari passu basis to the original Class B shares issued in December 2008 with a liquidation preference senior to Class A, Class O and ordinary shares. The events above in the aggregate had a downward effect on the valuation of the ordinary shares as of the end of 2011 and in 2012.
 
The ordinary shares valuation as of September 30, 2012 and December 5, 2012 relied on a DCF as well as the prior sale of Company stock method in connection with the January 2012 financing round to derive the total enterprise value. There were no events between the respective valuation dates and therefore the analyses and inputs remained the same. The cash flow projections were based on probability-weighted scenarios which considered estimates of time to market of the products, market share and pricing. Projections were updated from the December 2010 valuation for anticipated timing of placebo-controlled clinical trial results, the progress since the last valuation date and the development of a competing drug for DMD that increased the risk of the losing a first-mover advantage. A WACC of 15.5% was applied. Under the prior sale of Company stock method, the Company used the implied value from the latest financing round in January 2012 and an estimated annualized return on equity over the period between the financing round and the valuation date for the valuation of the enterprise value as of September 30, 2012 considering the factors noted above. Equity was allocated using the OPM, resulting in a value per ordinary share of €0.70. The OPM relies on the anticipated timing and probability of a liquidity event based on then current plans and estimates of the supervisory board and management board regarding a liquidity event of 80-85% probability of the sale of the Company and 15-20% probability of an IPO. The Company assumed volatility of 80% based on historical trading volatility for the publicly traded peer companies and a time to liquidity of 0.50 years.
 
A discount for lack of marketability (DLOM) of 15% and 10%, as of December 2010 and September 30, 2012, respectively, was applied to reflect the increased risk arising from the inability to readily sell the shares. When applying the DLOM, the Black-Scholes option model was used. Under this method, the cost of the put option, which can hedge the price change before the privately held shares can be sold, was considered as the basis to determine the DLOM. The cost of the put option was the only factor considered and applied in the discount. The put option analysis reflects the potential loss from marketability over the expected time to liquidity and is a commonly applied approach to estimate this discount.
 
The Company expects all vested options to be exercised. Prior to our IPO, the Company considered the expected life of the options to be in line with the vesting period of the options. The expected life for all options granted subsequent to the completion of our IPO is estimated at six years.
 
Prior to our initial public offering, the Company was a private company and lacked company-specific historical and implied volatility information and therefore estimated the expected volatility based on the historical volatility of certain publicly traded peer companies.  Volatility was set at 100% for options granted in 2014 and after the IPO on July 3, 2013, at 95% for options granted before July 3, 2013 and at 80% for options granted in 2012.
 
See note 24 for the total expense recognized in the income statement for share options and other share-based payment granted to managing directors, supervisory directors and selected employees. Share option expenses are accounted for as a contribution to equity and separately accounted for as other reserves.
 
Restricted shares
 
In 2012, the Company made, as part of the share-based compensation plan, awards entitling recipients to acquire Depositary Receipts (Restricted Shares) against payment of the nominal value of the underlying ordinary shares (the Purchase Price), subject to the right to repurchase all or part of such Depositary Receipts at the lower of the Purchase Price and the fair value of the ordinary shares during the four year vesting period if the participant ceases to perform services to the Company. The Company has the right to repurchase 100%
 

 
of the Restricted Shares awarded, and this right to repurchase shares will be reduced based on the following schedule: (a) 25% on a date of the year following the vesting commencement date no later than the anniversary of the grant, and (b) the remaining 75% in 36 equal monthly installments over a three year period following the first anniversary of the first vesting date.

During 2014 and 2013, the Company issued nil Restricted Shares (2012: 115,000). Restricted shares have a vesting period up to 4 years. The fair value of the Restricted Shares granted in 2012 of €0.70  was measured based on the estimated fair value of the ordinary shares at the moment of purchase, which amounted to €0.70 in line with the valuations of the ordinary shares. The Company is not in a financial position to pay dividends in the foreseeable future. Therefore dividend payments have not been considered in the valuation of the restricted share awards.
 
Following the public offer of BioMarin of 100% of the Company’s outstanding stock, all granted options and share-based payments would automatically vest at the date of the transaction. On January 15, 2015, BioMarin announced that the transaction was completed and subsequently all share awards fully vested. At December 31, 2014, the Company revised its estimate of the number of equity instruments that are expected to vest and accelerated the vesting period in light of the transaction with BioMarin. The share-based payment expense related to the Restricted Shares amount to €62 thousand in 2014, €57 thousand in 2013 and €18 thousand in 2012, which is included in the total share-based payment expense for the year disclosed (note 24).
 
On October 10, 2013 the Board of the Foundation resolved to terminate the administration of the ordinary shares and to transfer the ordinary shares to the respective Depository Receipt holder. After the completion of the transfers, the Foundation was dissolved. Going forward participants will receive ordinary shares upon the exercise or award or vesting of a non-cash-settled award under the plans instead of Depository Receipts.

Royalties LUMC
 
In 2008 Prosensa and Leiden Universitair Medisch Centrum (LUMC) extended and amended a research and license agreement with respect to commercialization of therapeutic products based on LUMC intellectual property rights and the joint technologies. Under this agreement the Company is obliged to make milestone payments upon the occurrence of events with respect to each subfield in which the Company pursues a drug indication using the LUMC patent rights, including commencing the first toxicity study, successfully completing the first Phase I study, filing for regulatory approval and satisfying certain sales thresholds. The aggregate milestone payments could total approximately €1.4 million if the Company achieves such milestones in relation to an initial orphan drug indication. If the Company achieves such milestones in relation to a non-orphan drug indication, the aggregate milestone payments could total €5.5 million. The Company may also be obligated to pay LUMC additional milestone payments of €1.25 million per product in relation to products approved for additional orphan drug indications. In addition, the Company is obligated to pay LUMC a mid-single digit percentage royalty on net sales on a country-by-country basis if and when any of the Company’s products is brought to market. If the Company sublicenses its rights under the LUMC agreement to a third party, the Company is obligated to pay LUMC a tiered royalty percentage (ranging from the low-to-mid-twenties) on the net licensing income and a low single-digit percentage royalty on the net sales generated by the sublicensee.
 
In relation to this agreement as of December 31, 2014 and 2013 no amounts were outstanding.

Bank borrowings
 
In 2006 the Company received a bank loan of €900 thousand from ABN Amro N.V. The loan bears interest equal to Euribor plus 1.75% per year. The Company fully repaid the amount outstanding per December 31, 2013 of €400 thousand in 2014.
 
Other loans
 
As part of the Asset Purchase Agreement dated February 12, 2015, the Assets and Liabilities of the Company, including the loans described below, were transferred and the Company would be indemnified and hold harmless for any liability that could not be transferred.
 
On August 11, 2014 the Company entered into an agreement to sell unsecured convertible notes to an affiliate of CureDuchenne, a non-profit organization. A note with a principal amount of €500 thousand was outstanding as of December 31, 2014. The note must be repaid on the earliest to occur of a change in control, twelve months from when the Company obtains regulatory approval of its first product candidate and June 30, 2019. CureDuchenne had the option, under specified conditions, to convert the notes prior to maturity into the Company’s ordinary shares with a maximum value of the notes’ principal and accumulated interest at a
 

 
conversion price based on the Company’s share price at the time of conversion including a discount. CureDuchenne did not convert the outstanding note.
 
The conversion option of the notes has been bifurcated and accounted for as a financial liability measured at fair value through profit and loss. The fair value of the embedded derivative is nil as of December 31, 2014.
 
On November 26, 2014 the Company entered into a convertible promissory note (the Note) to BioMarin Falcons B.V. for a principal amount of €40,355,125. The Note accrues interest at 6%. If prior to November 26, 2017, the Purchase Agreement with BioMarin terminates, the entire principal and accrued interest balance then outstanding would automatically be converted into 4,395,914 ordinary shares of the Company. The values of the liability component and the equity conversion component were determined at issuance of Note. The Note recognized in the balance sheet is calculated as follows:
 
€ (‘000)
 
2014
  
Face value of the Note issued on November 26, 2014
     40,355  
Equity component (note 15)
     (311 )
Liability component on initial recognition at November 26, 2014
     40,044  
Interest expense (note 26)
     450  
Liability component at December 31, 2014
     40,494  
 
The effect of a 1% increase in the probability assigned to the conversion would increase the fair value of the conversion feature by approximately €300 thousand. The effect of a 100 basis points increase in the estimated market interest rate would have an immaterial effect in the fair value of the liability component as of December 31, 2014.
 
The Company has obtained other loans from various governmental and non-profit groups. To encourage research and development the Company obtained certain loans that generally bear an interest rate below the market interest rate, considered by the Company to be 12% over the last years. The difference between fair value and the notional amount at inception is treated as a donation received for certain research performed by the Company. These borrowings were initially recognized at fair value at inception with the difference between the fair value and the notional amount recognized as other income in the statement of comprehensive income.
 
There is no exposure for the Company’s other borrowings to interest rate changes and contractual repricing. Interest rates are fixed until maturity. The fair values of the non-current borrowings approximate their carrying values. The fair value of current borrowings equals their carrying amount, as the impact of discounting is deemed immaterial. The carrying amounts of the Company’s borrowings are mostly denominated in Euros.
 
The key features of the other loans are described below.
 
a) Villa Joep
 
The principal amount of the loan is €65 thousand and was received on October 10, 2005. The loan bears a below market interest rate. No fixed redemption scheme was agreed on. The loan is not secured. The loan was repaid in the three months period ended March 31, 2015.
 
b) Association Française contre les Myopathies
 
On December 22, 2005 a loan of €70 thousand was granted. In 2006 an additional loan amount of €70 thousand was received. The loans shall be repaid with fixed terms when the Company obtains regulatory approval to bring the first product candidate to the market. The loans are interest free and are not secured.
 
In 2012 the Company received from Association Française contre les Myopathies €3.0 million related to a funding agreement for research and development in two separate installments on April 12, 2012 and December 21, 2012. In 2013 the Company received another installment of €250 thousand. The loans shall be
 

 
repaid with fixed terms when the Company meets a revenue target on the product candidates PRO044, PRO045 and PRO053. The loan was transferred to BioMarin in the three months period ended March 31, 2015.
 
c) Stichting Duchenne Parents Project
 
This loan of €500 thousand was received in two tranches, €300 thousand on July 14, 2006 and €200 thousand on October 10, 2006. No fixed redemption scheme was agreed on. The loan is not secured. The loan was repaid in the three months period ended March 31, 2015.
 
d) Aktion Benni & Co
 
On May 9, 2006 a loan of €100 thousand was granted that was received in two tranches in 2006. In 2008 an additional amount of €63 thousand was received. No interest is charged and no fixed redemption scheme was agreed. The loan shall be repaid after the Company obtains regulatory approval to bring the first product candidate to the market. The loan is not secured. The loan was repaid in the three months period ended March 31, 2015.
 
e) Cure Duchenne
 
The (subordinated) loan of €250 thousand was received on December 22, 2006 and bears a below market interest rate. No fixed redemption scheme was agreed. The loan as well as an additional payment of €250 thousand shall be repaid with fixed terms after the Company obtains regulatory approval to bring the first product candidate to the market. The loan is not secured. The loan was transferred to BioMarin in the three months period ended March 31, 2015.
 
f) Agentschap NL
 
The Company received loan installments from Agentschap NL for a total amount of €840 thousand which bears an interest rate of 9.5% per annum. In 2014, 2013 and 2012 the Company received €100, €99, and €165 thousand respectively. The granted loan is an innovation credit facility (Innovatiekrediet) of the Dutch Ministry of Economic Affairs.

Finance lease liabilities
 
Finance lease liabilities are effectively secured as the rights to the leased asset revert to the lessor in the event of default. The carrying amount corresponds to the fair value as terms of the contracts were agreed at arm’s length and market conditions for such contracts have not changed since. The interest rate imposed by the lessor for all finance lease liabilities is 8% per annum. The Company repaid all finance lease liabilities during the year ended December 31, 2014.

19. Revenue and deferred revenue
 
Until the termination of the GSK agreement, revenues have consisted principally of license revenue and collaboration revenue. The group generated both license revenue and collaboration revenue under the GSK Agreement.
 
License revenue
 
From October 2009 to January 2014, the Company operated under an exclusive worldwide collaboration with GSK for the development and commercialization of RNA-based therapeutics for DMD, with GSK exclusively licensing worldwide rights to develop and commercialize drisapersen and obtaining an option to exclusively license PRO044 and other specified assets in the Company’s DMD portfolio. Under the research and collaboration agreement, GSK paid the Company a total of £41.5 million (€47.4 million) in upfront and milestone payments. Under the research and collaboration agreement, GSK was responsible for all costs of clinical development of drisapersen.
 
On January 12, 2014, the research and collaboration agreement was mutually terminated pursuant to a termination agreement, which terminated all intellectual property license grants as well as any rights arising under the research and collaboration agreement (other than rights to payments that accrued prior to termination of the collaboration). In addition, the termination agreement required GSK to transfer to the Company certain data and know-how, inventory, regulatory filings, clinical trial sponsorships, clinical study reports and material agreements relating to the development of the Company’s products.
 

 
Going forward, the Company will be solely responsible for the cost of developing and commercializing drisapersen and its other product candidates, which may have significant financial and operational implications.
 
The agreement to terminate the research and collaboration agreement released the Company from any performance obligations under the upfront payments already received from GSK. As a result, during 2014, the Company recognized €14.5 million deferred license income. The release from any performance obligations also resulted in recognition of €0.2 million revenue related to other services delivered under the research and collaboration agreement with GSK.
 
The Company recorded license revenue as follows:

Collaboration revenue
 
Collaboration revenue from contracts, typically from delivering research and development services, which may or may not be related to the licensing agreement, is recognized on the basis of labor hours delivered at the contractual full time employee rates. During 2014, collaboration revenue was minimal due to the termination of the research and collaboration agreement (2013: €3.3 million; 2012: €2.1 million).
 
20. Other income
 
Other income for the year ended December 31, 2014 amounts to €741 thousand (2013: €560 thousand; 2012: €174 thousand). The Company is part of two pan-European consortia, each of which has been awarded a Framework Programme 7 (“FP7”) research grant of €6 million from the European Commission to support respectively ongoing clinical study PRO045 and the development of imaging biomarkers for Duchenne muscular dystrophy (DMD). Grant proceeds are deferred for an amount €502 thousand as of December 31, 2014 (2013: €218 thousand) and recognized in other income based on the percentage of completion method for an amount of €715 thousand in the year ended December 31, 2014 (2013: €485 thousand).
 
To encourage research and development the Company obtained certain loans that generally bear interest at a rate below the market interest rate, considered by the company to be 12% over the last five years. The difference between fair value and the notional amount at inception is treated as a donation received for certain research performed by the Company. As of December 31, 2014, an amount of €93 thousand (2013: €104 thousand) is deferred and will be recognized in other income over the periods during which expenses are incurred.

27. Income tax expense
 
No tax charge or income has been recognized in the years 2014, 2013 and 2012 since the Company is in a loss-making position and has a history of losses. Thus, no deferred tax asset has been recognized for carry-forward losses (note 4.2).
 
The Company has tax loss carry-forwards of approximately €112.4 million. An amount of €4.1 million relates to the pre-fiscal unity of the Prosensa Holding N.V. in liquidatie. As a result of the Dutch income tax law, tax loss carry-forwards are subject to a time limitation of nine years. Tax loss carry-forwards incurred in prior years will expire as follows:

Deferred income tax assets are recognized for tax losses and other temporary differences to the extent that the realization of the related tax benefit through future taxable profits is probable. Deferred tax assets and liabilities are offset if they pertain to future tax effects for the same taxable entity towards the same taxation authority.
 
No income taxes were paid and no deferred income tax was expensed or recognized through the income statement in the years ended December 31, 2014, 2013 and 2012. Losses are attributable to operations in the Netherlands.
 
As the Company’s temporary differences between tax gains / losses and current gains / losses, if any, are deemed immaterial and their realization is uncertain the Company refrains from further disclosures.
 
In order to promote innovative technology development activities and investments in new technologies, a corporate income tax incentive has been introduced in Dutch tax law called the Innovations Box. For the qualifying profits, the Company effectively owes only 5% income tax, should available tax losses carried forward have been utilized, instead of the general tax rate of 25% which results in an estimated effective tax rate of 10%. The agreement with the tax authorities is currently signed for the years 2011 – 2015 and is expected to be extended.
 
28. Loss per share
 
Basic
 
Basic loss per share is calculated by dividing the loss attributable to equity holders of the Company by the weighted average number of ordinary and preferred shares in issue during the year.

Diluted loss per share is calculated by adjusting the weighted average number of ordinary shares outstanding to assume conversion of all dilutive potential ordinary shares. Due to the fact that the Company is loss making all potential ordinary shares had an antidilutive effect, if converted, and thus have been excluded from the computation of loss per share.

In the normal course of business, the Company enters into contracts with CROs for the clinical trials and with vendors and institutions for safety and research studies, research supplies and other services and products for operating purposes. These contracts generally provide for termination on notice and the amounts are included as R&D expenses as services are provided.

The Company has pledged the part of its tangible and intangible fixed assets that directly relate to the project funded by the loan granted. The loan plus accrued interest was fully repaid in January 2015 and the pledge has been released in full.
 
31. Related-party transactions
 
The Supervisory Board members were paid €4 thousand during the years ended December 31, 2014 and 2013 and €7 thousand during the year ended December 31, 2012 for consulting services. The services were rendered at arm’s length.
 
Management Board and Supervisory Board compensation
 
In 2014, 2013 and 2012 the Management Board was paid a total of €1.4 million, €1.0 million and €1.6 million, respectively, in salaries, short term benefits and bonuses. In 2014, 2013 and 2012, €2,364 thousand, €764 thousand and €160 thousand, respectively, was expensed for share-based payment awards. Contributions to post employment schemes amounted to €202 thousand, €159 thousand and €161 thousand during the years ended December 31, 2014, 2013 and 2012, respectively. No termination benefits or other long term benefits were paid. The Management Board held 1,939 thousand, 1,559 thousand and 1,759 thousand stock options as of December 31, 2014, 2013 and 2012, respectively. In addition, the Management Board held 149 thousand restricted shares and 481 thousand ordinary shares as of December 31, 2014.
 
On December 5, 2012 the Management Board was granted 1.0 million stock options that vest subject to a liquidity event and continued employment. As of December 31, 2012 the requirements to vest were deemed not probable under an IPO Scenario, and de minimums under a change of control scenario, and therefore no expenses were recognized in the income statement. Following our initial public offering, the number of options eligible to vest automatically reduced from 1.0 million to 800,000.
 
Selected members of the Supervisory Board were paid in total an amount of €93 thousand during the year ended December 31, 2014 and €34 thousand and €50 thousand during the years ended December 31, 2013 and 2012 respectively.
 

 
At the annual general meeting of shareholders on June 14, 2013 the shareholders approved, conditional upon the completion of the IPO, an individual annual grant of 10,000 options to members of the Supervisory Board. In 2014, members of the Supervisory Board were granted 120,000 Options with exercise price between $6.2 and $10.8 (2013: 160,000 Options with an exercise price of $19.25; 2012: 15,000 Restricted Shares and 11,250 Options with an exercise price of €0.01).
 
Expenses of €818 thousand related to the granted options to members of the Supervisory Board were recognized during the period ended December 31, 2014. The Options and Restricted Shares were granted under the Company’s share based compensation plan (note 16).   
 
No loans, advances and guarantees were made to the Management Board and Supervisory Board members as of December 31, 2014, 2013 and 2012.

33. Contingent Liabilities
 
In July 2014, the Company and certain of its managing directors and supervisory directors were named as defendants in Singh v. Schikan et al., a purported class action lawsuit filed in the U.S. District Court for the Southern District of New York. The complaint asserts claims under the federal securities laws on behalf of a professed class consisting of all those who purchased the Company’s ordinary shares pursuant and/or traceable to the registration statement used in connection with the Company’s IPO. The complaint alleges that the Company omitted and/or misstated certain facts in the registration statement concerning the Phase III trial of drisapersen that, as announced on September 20, 2013, did not meet its primary endpoint. The litigation is in its earliest stages, and the Company and the individual defendants intend to defend the action vigorously. The Company is not able at present to reasonably estimate potential losses, if any, in connection with the litigation, but an adverse resolution could have a material adverse effect on the Company’s financial position, results of operations and cash flows.
 
34. Events after the balance sheet date
 
On December 12, 2014, BioMarin commenced a tender offer to acquire all of the ordinary shares of the Company in an all cash transaction for $17.75 per share for an upfront purchase price of approximately $680 million. In addition, for each share purchased, BioMarin issued one non-transferable contingent value right, which represents the contractual right to receive a cash payment of up to $4.14 per share, or approximately $160 million, upon the achievement of certain product approval milestones.

On January 15, 2015, BioMarin closed the initial offering period relating to the tender offer, purchased 93.4% of the Company shares and immediately launched a subsequent offering period that expired on January 29, 2015. As of the expiration of the subsequent offering period, BioMarin paid approximately $659.3 million for approximately 35.0 million shares, representing approximately 96.8% of all of the outstanding shares of Company and options that vested pursuant to the definitive purchase agreement. On February 12, 2015, BioMarin completed the asset transfer and paid an additional $20.8 million to the remaining shareholders of the Company. Effective February 12, 2015, the Company is in liquidation under Dutch law.

 
As a part of above asset transfer of February 12, 2015, the Company transferred the carrying value of the liability towards BioMarin Falcons B.V. (€40.5 million as per December 31, 2014; refer to note 18) plus accrued interest for 2015 until the transfer date, back to BioMarin Falcons B.V.
 
In view of the acquisition of the Company by BioMarin as referred to above, a selected number of borrowings as discussed in note 18 have been repaid by the Company or BioMarin in 2015; the total of repaid borrowings until the date of these financial statements amounted to €2.7 million, which approximates their carrying value at year end 2014 plus the accrued interest until payment in 2015. The repaid loans include the innovation credit facility (Innovatiekrediet), for which €840 thousand was received from Agentschap NL; the Company had pledged a part of its material and immaterial fixed assets that directly related to the project funded by this loan and this pledge was fully released following the repayment.
