NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. ORGANIZATION

Ascent Solar Technologies, Inc. (“Ascent”) was incorporated on October 18, 2005 from the separation by ITN Energy Systems, Inc. (“ITN”) of its Advanced Photovoltaic Division and all of that division’s key personnel and core technologies. ITN, a private company incorporated in 1994, is an incubator dedicated to the development of thin film, photovoltaic (“PV”), battery, fuel cell and nano technologies. Through its work on research and development contracts for private and governmental entities, ITN developed proprietary processing and manufacturing know how applicable to PV products generally, and to Copper-Indium-Gallium-diSelenide (“CIGS”) PV products in particular. ITN formed Ascent to commercialize its investment in CIGS PV technologies. In January 2006, in exchange for 102,800 shares of common stock of Ascent, ITN assigned to Ascent certain CIGS PV technologies and trade secrets and granted to Ascent a perpetual, exclusive, royalty free worldwide license to use, in connection with the manufacture, development, marketing and commercialization of CIGS PV to produce solar power, certain of ITN’s existing and future proprietary and control technologies that, although non-specific to CIGS PV, Ascent believes will be useful in its production of PV modules for its target markets. Upon receipt of the necessary government approvals and pursuant to novation in early 2007, ITN assigned government funded research and development contracts to Ascent and also transferred the key personnel working on the contracts to Ascent.

Currently, the Company is focusing on integrating its PV products into high value markets such as aerospace, satellites, near earth orbiting vehicles, and fixed-wing unmanned aerial vehicles (UAV). The value proposition of Ascent’s proprietary solar technology not only aligns with the needs of customers in these industries, but also overcomes many of the obstacles other solar technologies face in these unique markets. Ascent has the capability to design and develop finished products for end users in these areas as well as collaborate with strategic partners to design and develop custom integrated solutions for products like fixed-wing UAVs. Ascent sees significant overlap of the needs of end users across some of these industries and can achieve economies of scale in sourcing, development, and production in commercializing products for these customers.

NOTE 2. BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been derived from the accounting records of Ascent Solar Technologies, Inc., Ascent Solar (Asia) Pte. Ltd., and Ascent Solar (Shenzhen) Co., Ltd. (collectively, "the Company") as of March 31, 2019 and December 31, 2018 , and the results of operations for the three months ended March 31, 2019 and 2018 . Ascent Solar (Shenzhen) Co., Ltd. is wholly owned by Ascent Solar (Asia) Pte. Ltd., which is wholly owned by Ascent Solar Technologies, Inc. All significant inter-company balances and transactions have been eliminated in the accompanying consolidated financial statements.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 .

ASCENT SOLAR TECHNOLOGIES, INC.

NOTE 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company’s significant accounting policies were described in Note 3 to the audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . There have been no significant changes to our accounting policies as of March 31, 2019 .

Recently Adopted or to be Adopted Accounting Policies

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . ASU 2016-02 requires lessees to recognize all leases, including operating leases, on the balance sheet as a lease asset or lease liability, unless the lease is a short-term lease. ASU 2016-02 also requires additional disclosures regarding leasing arrangements. ASU 2016-02 is effective for interim periods and fiscal years beginning after December 15, 2018, and early application is permitted. The Company has evaluated the adoption of this guidance and has determined there is no material impact on its consolidated financial statements because the Company does not have any leases at the date of the adoption.

In July 2017, the FASB issued ASU No. 2017-11 Part I, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815) . ASU 2017-11 Part I changes the classification analysis of certain equity linked financial instruments with down round features. ASU 2017-11 Part I is effective, for public business entities, for interim periods and fiscal years beginning after December 15, 2018, and early application is permitted. The adoption of this guidance did not have a material impact on its consolidated financial statements.

In June 2018, the FASB issued ASU No. 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Payment Accounting , which simplifies the accounting for share-based payments to non-employees by aligning it with the accounting for share-based payments to employees, with specified exceptions. This standard is effective for the Company in the first quarter of 2020, and early adoption is permitted. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement , which modifies the disclosure requirements of fair value measurements. This standard is effective for the Company in the first quarter of 2020, and early adoption is permitted. The Company is currently evaluating the impact of the effect adoption of this standard will have on its consolidated financial statements.

Other new pronouncements issued but not effective as of March 31, 2019 are not expected to have a material impact on the Company’s consolidated financial statements.

NOTE 4. LIQUIDITY, CONTINUED OPERATIONS, AND GOING CONCERN

During the three months ended March 31, 2019 and the year ended December 31, 2018 , the Company entered into multiple financing agreements to fund operations. Further discussion of these transactions can be found in Notes 8, 9, 10, 11, 12, and 16.

The Company has continued limited PV production at its manufacturing facility. The Company does not expect that sales revenue and cash flows will be sufficient to support operations and cash requirements until it has fully implemented its product strategy. During the three months ended March 31, 2019 the Company used $1,161,889 in cash for operations. The Company's primary significant long term cash obligation consists of a note payable of $5,292,931 to a financial institution secured by a mortgage on its headquarters and manufacturing building in Thornton, Colorado. Total payments of approximately $693,611 , including principal and interest, will come due in the remainder of 2019.

On April 12, 2019, the Company entered into an agreement for the sale of its Thornton, Colorado building at a gross sales price of $13 million . The closing of the transaction, which is subject to customary closing conditions, is expected to close in the third quarter of 2019.

Additional projected product revenues are not anticipated to result in a positive cash flow position for the next twelve months overall and, as of March 31, 2019 , the Company has negative working capital. As such, cash liquidity sufficient for the next twelve months will require additional financing.

Table of Contents

ASCENT SOLAR TECHNOLOGIES, INC.

The Company continues to accelerate sales and marketing efforts related to its consumer and military solar products and specialty PV application strategies through expansion of its sales and distribution channels. The Company has begun activities related to securing additional financing through strategic or financial investors, but there is no assurance the Company will be able to raise additional capital on acceptable terms or at all. If the Company's revenues do not increase rapidly, and/or additional financing is not obtained, the Company will be required to significantly curtail operations to reduce costs and/or sell assets. Such actions would likely have an adverse impact on the Company's future operations.

As a result of the Company’s recurring losses from operations, and the need for additional financing to fund its operating and capital requirements, there is uncertainty regarding the Company’s ability to maintain liquidity sufficient to operate its business effectively, which raises substantial doubt as to the Company’s ability to continue as a going concern. The Company has scaled down its operations, due to cash flow issues, and does not expect to ramp up until significant financing is obtained.

Management cannot provide any assurances that the Company will be successful in accomplishing any of its plans. These consolidated financial statements do not include any adjustments that might be necessary should the Company be unable to continue as a going concern.

NOTE 8. DEBT

On February 8, 2008 , the Company acquired a manufacturing and office facility in Thornton, Colorado, for approximately $5.5 million. The purchase was financed by a promissory note, deed of trust and construction loan agreement (the “Construction Loan”) with the Colorado Housing and Finance Authority (“CHFA”), which provided the Company borrowing availability of up to $7.5 million for the building and building improvements. In 2009 , the Construction Loan was converted to a permanent loan pursuant to a Loan Modification Agreement between the Company and CHFA (the “Permanent Loan”). The Permanent Loan, collateralized by the building, has an interest rate of 6.6% and the principal will be amortized through its term to February 2028 . Further, pursuant to certain negative covenants in the Permanent Loan, the Company may not, among other things, without CHFA’s prior written consent (which by the terms of the deed of trust is subject to a reasonableness requirement): create or incur additional indebtedness (other than obligations created or incurred in the ordinary course of business); merge or consolidate with any other entity; or make loans or advances to the Company’s officers, shareholders, directors or employees.

On November 1, 2016 , the Company and the CHFA agreed to modify the original agreement described above with the addition of a forbearance period. Per the modification agreement, no payments of principal and interest shall be due under the note during the forbearance period commencing on November 1, 2016 and continuing through April 1, 2017 . The amount of interest that should have been paid by the Company during the forbearance period in the total amount of $180,043 was added to the outstanding principal balance of the note. As a result, on May 1, 2017 , the principal balance of the note was $5,704,932 . Commencing on May 1, 2017 , the monthly payments of principal and interest due under the note resumed at $57,801 , and the Company shall continue to make such monthly payments over the remaining term of the note ending in February 2028 .

On August 24, 2018 , the Company and the CHFA agreed to modify the original agreement with an additional forbearance period. Per the modification agreement, no payments of principal shall be due under the note during the forbearance period commencing on June 1, 2018 and continuing through November 30, 2018 . For each month of forbearance, partial interest of $15,000 per month was paid, and the remaining unpaid interest of the forbearance period of $84,187 was added to the outstanding principal balance of the note. As a result, on December 1, 2018 , the principal balance of the note will be $5,434,042 and monthly payments of principal and interest of $57,801 will resume, continuing through the remaining term of the note ending in February 2028 .

All the notes issued in accordance with the note purchase and exchange agreement dated November 30, 2017 are secured by a security interest on substantially all of the Company’s assets, bear interest at a rate of 12% per annum and contain standard and customary events of default including but not limited to: (i) failure to make payments when due under the notes, and (ii) bankruptcy or insolvency of the Company. There are no registration rights applicable to the notes.

As of March 31, 2019 , the aggregate principal and interest balance of the Notes were $5,012,897 and $432,254 , respectively.

Pursuant to a number of factors outlined in ASC Topic 815, Derivatives and Hedging , the conversion option in the notes were deemed to include an embedded derivative that required bifurcation and separate accounting. As such, the Company ascertained the value of the conversion option as if separate from the convertible issuance and appropriately recorded that value as a derivative liability. The fair value measurements rely primarily on Company-specific inputs and the Company’s own assumptions. With the absence of observable inputs, the Company determined these recurring fair value measurements reside primarily within Level 3 of the fair value hierarchy. The derivative associated with the notes approximates management’s estimate of the fair value of the embedded derivative liability based on using a Monte Carlo simulation following a Geometric Brownian Motion with the following assumptions identified below.

The following table summarizes the derivative liability transactions for these notes:



Derivative Liability Balance as of December 31, 2018	$	3,533,861
Change in fair value of derivative liability	(1,858,961		)
Derivative Liability Balance as of March 31, 2019	$	1,674,900

Due to the varying terms and varying issue dates, the tranches of this instrument were broken into five separate instruments for valuation purposes.


1)	The first valuation was done on the November 30, 2017 note with term of three years. The derivative value of this note was $1,764,068 as of December 31, 2018 .


2)	The second valuation was done on the group of notes dated November 30, 2017 , that had a term of one year. The derivative value of this group of notes was $418,965 as of December 31, 2018 .


3)	The third valuation was done on the note dated December 28, 2017 , which had a term of one year. The derivative value of this note was $150,126 on December 31, 2018 .


4)	The fourth valuation was done for the notes dated in the first quarter of 2018, which had a term of one year . The derivative value of this note was $900,757 on December 31, 2018 .


5)	The fifth valuation was done for the notes dated in the fourth quarter of 2018, which had a term of one year . The derivative value of this note was $299,945 on December 31, 2018 .

The derivative liability associated with the notes is subject to revaluation on a quarterly basis to reflect the market value change of the embedded conversion option. At March 31, 2019 , the Company conducted a fair value assessment of the embedded derivative associated with the three valuation groups discussed above.

Table of Contents

ASCENT SOLAR TECHNOLOGIES, INC.

All principal and accrued interest on the convertible notes is convertible at any time, in whole or in part, at the option of the investor, into shares of common stock at a variable conversion price equal to 80% of the lowest closing bid price of the Company’s common stock for the fifteen consecutive trading day period prior to the conversion date. After the six month anniversary of the issuance of any convertible note, the conversion price for such note shall thereafter be equal to 50% of the lowest closing bid price of the Company’s common stock for the fifteen consecutive trading day period prior to the conversion date.

The convertible notes contain standard and customary events of default including but not limited to: (i) failure to make payments when due under the convertible notes; and (ii) bankruptcy or insolvency of the Company.

Outstanding principal and accrued interest on the convertible notes were $330,000 and $49,885 , respectively as of March 31, 2019 .

Pursuant to a number of factors outlined in ASC Topic 815, Derivatives and Hedging , the conversion option in the convertible notes were deemed to include an embedded derivative that required bifurcation and separate accounting. As such, the Company ascertained the value of the conversion option as if separate from the convertible issuance and appropriately recorded that value as a derivative liability. As of December 31, 2018 , the fair value of the derivative liability was $876,481 .

The following table summarizes the derivative liability transactions for this note:



Derivative Liability Balance as of December 31, 2018	$	876,481
Additional derivative liability on new notes	—
Change in fair value of derivative liability	(481,408		)
Derivative Liability Balance as of March 31, 2019	$	395,073

At March 31, 2019 , the Company conducted a fair value assessment of the embedded derivative associated with the convertible notes. As a result of the fair value assessment, the Company recorded a $481,408 gain as "Change in fair value of derivatives and gain/(loss) on extinguishment of liabilities, net" in the Consolidated Statements of Operations for the three months ended March 31, 2019 , to properly reflect the fair value of the embedded derivative of $395,073 as of March 31, 2019 .

The fair value measurements rely primarily on company-specific inputs and the Company’s own assumptions. With the absence of observable inputs, the Company determined these recurring fair value measurements reside primarily within Level 3 of the fair value hierarchy. The derivative associated with the convertible notes approximates management’s estimate of the fair value of the embedded derivative liability at March 31, 2019 based on using a Monte Carlo simulation following a Geometric Brownian Motion with the following assumptions: annual volatility of 72% , present value discount rate of 12% , and dividend yield of 0% .

Derivative Liability Balance as of March 31, 2019	$	176,087

At December 31, 2018 , the derivative liability associated with Exchange Note 2 was $113,846 . During the three months ended March 31, 2019 , Exchange Note 2 had been fully converted and the remaining derivative liability of $113,846 was recorded as a gain to "Change in fair value of derivatives and gain/(loss) on extinguishment of liabilities, net" in the Consolidated Statements of Operations.

The conversion options in Exchange Notes 3 & 4 were deemed to include an embedded derivative that required bifurcation and separate accounting. As such, the Company ascertained the value of the conversion option as if separate from the convertible issuance and appropriately recorded that value as a derivative liability. At March 11, 2019 , the derivative liability associated with Exchange Notes 3 & 4 was $310,640 . The fair value of the derivative was greater than the face value at issuance and the difference of $57,204 was charged to interest expense at issuance. The remaining debt discount of $253,436 will be charged to interest expense ratably over the life of the note.

The derivative liability associated with these notes is subject to revaluation on a quarterly basis to reflect the market value change of the embedded conversion option. At March 31, 2019 , the Company conducted a fair value assessment of the embedded derivative associated with the Exchange Notes 3 & 4. As a result of the fair value assessment, the Company recorded a $134,553 gain as "Change in fair value of derivatives and gain/(loss) on extinguishment of liabilities, net" in the Consolidated Statements of Operations for the three months ended March 31, 2019 to properly reflect the fair value of the embedded derivative of $176,087 as of March 31, 2019 .

The fair value measurements rely primarily on company-specific inputs and the Company’s own assumptions. With the absence of observable inputs, the Company determined these recurring fair value measurements reside primarily within Level 3 of the fair value hierarchy. The derivative associated with Exchange Notes 3 & 4 approximates management’s estimate of the fair value of the embedded derivative liability at March 31, 2019 based on using a Monte Carlo simulation following a Geometric Brownian Motion with the following assumptions: annual volatility of 69% , present value discount rate of 12% and dividend yield of 0% .

The Certificate of Amendment provides that the Reverse Stock Split became effective as of 5:00 p.m. Eastern Time on July 20, 2018 (the “Effective Time”), at which time every thousand shares of the Company’s issued and outstanding Common Stock were automatically combined into one issued and outstanding share of Common Stock, without any change in the par value per share. The Certificate of Amendment provides that in the event a stockholder would otherwise be entitled to receive a fraction of a share of Common Stock, such stockholder shall receive one whole share of Common Stock in lieu of such fractional share and no fractional shares shall be issued.

Immediately following the Reverse Stock Split, the Company had approximately 19 million shares of Common Stock issued and outstanding.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of our financial condition and results of operations should be read in conjunction with our unaudited financial statements and the notes to those financial statements appearing elsewhere in this Form 10-Q. This discussion and analysis contains statements of a forward-looking nature relating to future events or our future financial performance. As a result of many factors, our actual results may differ materially from those anticipated in these forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements.

Overview

We are a company formed to commercialize flexible PV modules using our proprietary technology. For the three months ended March 31, 2019 , we generated $215,384 of revenue. Our revenue of $215,384 from product sales accounted for 100% of total revenue, we did not have any revenue generated from government research and development contracts during the three months ended March 31, 2019 . As of March 31, 2019 , we had an accumulated deficit of approximately $415 million.

In January 2017, Ascent was awarded a contract to supply high-voltage SuperLight thin-film CIGS PV blankets. These 50W, fully laminated, flexible blankets were manufactured using a new process that was optimized for high performance in near-space conditions at elevated temperatures, and are custom designed for easy modular integration into series and parallel configurations to achieve the desired voltage and current required for such application.

During the third quarter of 2017, Ascent Solar was selected by Energizer to develop and supply solar panels for their PowerKeep line of solar products, and in November 2017, Ascent introduced the next generation of our USB-based portable power systems with the XD™ series. The first product introduced was the XD-12 which, like previous products, is a folding, lightweight, easily stowable, PV system with USB power regulation. Unique to this generation of PV portable power is more PV power (12 Watts) and a 2.0 Amp smart USB output to enable the XD-12 to charge most smartphones, tablets, and USB-enabled devices as fast as a wall outlet. The enhanced smart USB circuit works with the device to be charged so that the device can determine the maximum power it is able to receive from the XD-12, and ensures the best possible charging performance directly from the sun.

Also in 2017, for a space customer, Ascent manufactured a new micro-module, approximately 12.8mm x 50mm (0.5in x 2.0in) in size that is ideal for both laboratory-scale environmental testing, and for subsequent integration into flight experiments.

In February 2018, the Company introduced the second product in our XD series. Delivering up to 48 Watts of solar power, the durable and compact Ascent XD-48 Solar Charger is the ideal solution for charging many portable electronics and off-grid power systems. The XD-48’s versatility allows it to charge both military and consumer electronics directly from the sun wherever needed. Like the XD-12, the XD-48 has a compact and portable design, and its rugged, weather-resistant construction withstands shocks, drops, damage and even minor punctures to power through the harshest conditions.

In March 2018, Ascent successfully shipped to a European based customer for a lighter-than-air, helium-filled airship project based on our newly developed ultra-light modules with substrate material than half of the thickness of our standard modules.

We continue to design and manufacture PV integrated consumer electronics as well as portable power applications for commercial and military users. Due to the high durability enabled by the monolithic integration employed by our technology, the capability to customize modules into different form factors and the industry leading light weight and flexibility provided by our modules, we believe that the potential applications for our products are numerous.

Table of Contents

Commercialization and Manufacturing Strategy

We manufacture our products by affixing a thin CIGS layer to a flexible, plastic substrate using a large format, roll-to-roll process that permits us to fabricate our flexible PV modules in an integrated sequential operation. We use proprietary monolithic integration techniques which enable us to form complete PV modules with little to no costly back end assembly of inter cell connections. Traditional PV manufacturers assemble PV modules by bonding or soldering discrete PV cells together. This manufacturing step typically increases manufacturing costs and at times proves detrimental to the overall yield and reliability of the finished product. By reducing or eliminating this added step using our proprietary monolithic integration techniques, we believe we can achieve cost savings in, and increase the reliability of, our PV modules. All tooling necessary for us to meet our near term production requirements is installed in our Thornton, Colorado plant. In 2012, we further revised our strategy to focus on applications for emerging and high-value specialty PV markets, including off grid, aerospace, military and defense and consumer oriented products.

We plan to continue the development of our current PV technology to increase module efficiency, improve our manufacturing tooling and process capabilities and reduce manufacturing costs. We also plan to continue to take advantage of research and development contracts to fund a portion of this development.

Significant Trends, Uncertainties and Challenges

We believe the significant trends, uncertainties and challenges that directly or indirectly affect our financial performance and results of operations include:


•	Our ability to generate customer acceptance of and demand for our products;


•	Successful ramping up of commercial production on the equipment installed;

Liquidity and Capital Resources

Table of Contents

Additional projected product revenues are not anticipated to result in a positive cash flow position for the year 2019 overall and, as of March 31, 2019 , the Company has negative working capital. As such, cash liquidity sufficient for the next twelve months will require additional financing.

Statements of Cash Flows Comparison of the Three Months Ended March 31, 2019 and 2018

For the three months ended March 31, 2019 , our cash used in operations was $1,161,889 compared to $1,494,744 for the three months ended March 31, 2018 , a decrease of $332,855 . The decrease is primarily the result of reduced operations during the current year. For the three months ended March 31, 2019 , cash used in investing activities was $2,131 compared to $6,502 for the three months ended March 31, 2018 . This decrease was the result of reduced spending on patents. During the three months ended March 31, 2019 , negative operating cash flows of $1,161,889 million were funded through $1,201,768 million in new debt issuances, offset by payment of financing costs of $5,000 .

Off Balance Sheet Transactions

As of March 31, 2019 , we did not have any off balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Exchange Risk

We hold no significant funds and have no future obligations denominated in foreign currencies as of March 31, 2019 .

Although our reporting currency is the U.S. Dollar, we may conduct business and incur costs in the local currencies of other countries in which we may operate, make sales and buy materials. As a result, we are subject to currency translation risk. Further, changes in exchange rates between foreign currencies and the U.S. Dollar could affect our future net sales and cost of sales and could result in exchange losses.

Interest Rate Risk

Our exposure to market risks for changes in interest rates relates primarily to our cash equivalents and investment portfolio. As of March 31, 2019 , our cash equivalents consisted only of operating accounts held with financial institutions. From time to time, we hold restricted funds, money market funds, investments in U.S. government securities and high quality corporate securities. The primary objective of our investment activities is to preserve principal and provide liquidity on demand, while at the same time maximizing the income we receive from our investments without significantly increasing risk. The direct risk to us associated with fluctuating interest rates is limited to our investment portfolio, and we do not believe a change in interest rates will have a significant impact on our financial position, results of operations, or cash flows.

Table of Contents

Credit Risk

From time to time, we hold certain financial and derivative instruments that potentially subject us to credit risk. These consist primarily of cash, cash equivalents, restricted cash, investments, and forward foreign currency option contracts. We are exposed to credit losses in the event of nonperformance by the counter parties to our financial and derivative instruments. We place cash, cash equivalents, investments and forward foreign currency option contracts with various high quality financial institutions, and exposure is limited at any one institution. We continuously evaluate the credit standing of our counter party financial institutions.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms. Our disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosures. Our management conducted an evaluation required by Rules 13a-15 and 15d-15 under the Exchange Act of the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15 and 15d-15 under the Exchange Act as of March 31, 2019 . Based on this evaluation, our management concluded the design and operation of our disclosure controls and procedures were not effective as of March 31, 2019 .

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our system of internal control over financial reporting is 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 ("GAAP") in the United States of America and includes those policies and procedures that:


•	pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;


•	provide reasonable assurance transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and


•	provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Under the supervision of the Audit Committee of the Board of Directors and with the participation of our management, including our Chief Executive Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting using the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, our management concluded our internal controls over financial reporting were not effective as of March 31, 2019 . Our management reviewed the results of its assessment with the Audit Committee.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 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.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis.

Material Weakness

Based on our assessment and the criteria used, management concluded that our internal control over financial reporting as of March 31, 2019 was not effective due to the material weaknesses described as follows:

Table of Contents


•	The Company was understaffed and did not have sufficiently trained resources with the technical expertise to ensure that all company transactions were accounted for in accordance with GAAP. This deficiency arose primarily from staff turnover and the inability of the Company to devote sufficient replacement resources in a timely manner, as a result of the Company's financial situation

As a consequence, the Company did not have effective process level control activities over the following:


•	Accounting for the Company's inventory and cost of revenue was lacking for the preparation of the March 31, 2019 financial statements. Miscalculations in these areas could impact the Company's current assets, revenues, operating results, and cash flows.

The control deficiencies described above created a reasonable possibility that a material misstatement to the consolidated financial statements would not be prevented or detected on a timely basis. The control deficiencies described above resulted in material misstatements in the preliminary consolidated financial statements that were corrected prior to the issuance of the consolidated financial statements as of and for the fiscal year ended March 31, 2019 .

Remediation Plan for Material Weaknesses in Internal Control over Financial Reporting

The Company plans to executed the following steps in 2019 to remediate the aforementioned material weaknesses in its internal control over financial reporting:


•	The Company plans to engage a resource, either as internal staff or an external contractor, with the technical expertise to track and report on inventory transactions and cost of revenue calculations.


•	The Company will design and implement additional procedures in order to assure that the resource mentioned above and other audit/accounting personnel are more involved with the Company’s inventory activities and cost of revenue allocations to monitor and earlier identify accounting issues that may be raised by the Company’s ongoing activities.

Changes in Internal Control Over Financial Reporting

Except for the identification and mitigation of the material weaknesses noted above, there were no other changes in internal control over financial reporting during the year ended March 31, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
