Fresnillo plc

Financial results for the year ended 31 December 2018

Fresnillo plc today announced its financial results for the full year ended 31 December 2018. Octavio Alvídrez, CEO said:

"Since we listed on the London Stock Exchange in 2008, we have successfully built a track record of creating value through growth and returns. We have remained committed to our stated strategy, investing in our business, growing production and delivering returns to our shareholders in what has been a volatile time for the wider mining sector.

2018 was however a more challenging year for Fresnillo.

We achieved record annual silver production of 61.8 moz and a very strong gold performance of 923 koz in 2018. Gold production surpassed the expectations we had at the beginning of the year. Despite the year on year increase in silver production, we reported lower silver production than anticipated and were disappointed not to meet our long-term silver target of 65 moz. This was mainly due to lower than expected ore grades at the Fresnillo and Saucito mines combined with some operational issues.

We are taking action to address this, not least by intensifying our infill drilling programmes, controlling dilution and further investment in equipment and infrastructure. The flotation plant to process historical and ongoing tailings at the Fresnillo mine is progressing and is expected to improve overall recoveries once completed. We have also invested in innovative technology to improve productivity with a new state-of-the-art tunnelling machine due to be commissioned in 2019.

A more challenging operating environment was also reflected in the financial performance for the year, with gross profit and EBITDA decreasing by 15.6% and 13.7% respectively, though margins remained strong. This decrease in gross profit was driven by the higher stripping ratio at Herradura, as well as higher depreciation and increased cost inflation across the Group, amongst other factors. These adverse factors were mitigated by the reassessment of inventories at Herradura as well as the higher production at San Julián (Disseminated Ore Body) following its first full year in operation.

We maintained a solid financial position, with US$560.8 million in cash and other liquid funds notwithstanding paying dividends of US$298.1 million, investing US$668.7 million in capex and spending US$172.8 million in exploration. The Board has recommended a final dividend of US$16.7 cents per share, bringing the total paid for the year to US$201.9 million.

Core to our organic growth strategy is ensuring we deliver on the potential of our existing assets while expanding our development pipeline.

I fully expect to be able to make a further positive announcement on our Juanicipio development project in due course. This joint venture project is expected to further contribute to silver and gold production, delivering high returns for our business while generating additional employment in the area. With first production anticipated in the second half of 2020, Juanicipio reaffirms the world-class status of the Fresnillo district and underlines the extent of the resources that have already been discovered there, as well as those that await discovery in the future.

We have also progressed our other development projects. The first stage of the new Pyrites plant has now been commissioned. The plant will make an important contribution to production by extracting additional quantities of gold and silver from the historical and ongoing tailings at the Fresnillo and Saucito mines. We were also pleased to commission the second line at the Dynamic Leaching Plant (DLP) at Herradura during the year.

Another point of difference for Fresnillo is our commitment to maintaining a strong exploration pipeline. We continued to make good progress at Orisyvo and Guanajuato, while the project at Rodeo is showing positive signs. At the end of 2018, our silver resources stood at 2.2 boz, down by 5.0% over the previous year, with our exploration mining concessions amounting to 1.8 million hectares in Mexico. Our gold resources increased by 1.5% during the year to 39.1 moz. In 2018 we also progressed our international pipeline, with exploration prospects in Chile and Peru.

The safety of our employees and contractors is the absolute priority for the Board. So it is with deep regret I confirm five fatalities during the year and one more at the beginning of 2019. We must do better. The safety of our workforce is at the top of our HSECR agenda for 2019, and we will renew our efforts to align employees and contractors alike with our safety culture.

Looking ahead, I expect 2019 to be another challenging year. We face a number of headwinds, including lower prices for precious metals and higher inflation. I also expect to see higher depreciation costs as a result of the investments we have made in recent years into the operations, while we continue to expect to work through operational issues and lower grades at certain mines during the year. All this has resulted in us slightly lowering our silver production guidance for 2019.

Our strategic goals remain unchanged, and we are committed to maintaining our position as the world's largest primary silver company and a leading gold producer in Mexico. Our model is proven, our people are skilled, experienced and dedicated, and a track record of creating value through growth and returns will continue to be our defining characteristic."

2018 Highlights

Challenging operational environment impacted financial performance

-- Adjusted revenue of US$2,243.4 million, 0.5% increase vs. 2017 primarily due to record silver, lead and zinc volumes sold offset by lower prices.

-- Higher adjusted production costs, up 23.8%, mainly driven by the higher stripping ratio at Herradura, cost inflation and additional costs associated with higher volumes produced.

-- Gross profit of US$780.7 million down 15.6% respectively mainly due to lower prices, higher adjusted production costs and increased depreciation. Healthy profit margin maintained (37.1%).

   --      Exploration spend of US$172.8 million, up 22.5%. 

-- Profit from continuing operations of US$506.7 million, down 28.6% as a result of lower gross profit and higher exploration and administrative expenses.

-- Profit for the year of USD$350.0 million, down 37.6% on 2017 mainly due to the lower profit from continuing operations and the US$22.5 million Silverstream revaluation loss recognised in 2018, compared to the US$70.3 million gain in 2017.

-- Cash generated by operations before changes in working capital decreased by 13.3% to US$930.7 million (2017: US$1,073.9 million).

-- Capital expenditures of US$668.7 million, up 10.6% vs 2017 but below guidance, mainly due to the delay in the start of the construction of the Juanicipio project.

-- Maintained financial flexibility, with year-end cash and other liquid funds[1] of US$560.8 million (2017: US$896.1 million).

-- Basic and diluted EPS from continuing operations of US$0.475; adjusted EPS of US$0.461, down 37.6% and 29.4% respectively.

-- 2018 final dividend of US$16.7 cents per share, equivalent to approximately US$123.1 million, recommended by the Board

Delivering on the potential of existing assets while expanding development pipeline

-- Commissioned the leaching plant at Saucito in 2Q18, the first phase of this US$155 million Pyrites Plant project in the Fresnillo district.

-- Construction of the US$110 million second line of the Dynamic Leaching Plant at Herradura completed in 2018, albeit minor delays due to a longer testing period.

   --      Juanicipio project continued to advance and Board approval is expected in due course. 

-- Gold resources increased 1.5% mainly due to positive results at Centauro Deep; silver resources down 5.0% as a result of lower ore grade and tonnage at Saucito. Gold reserves declined 6.0% due to depletion at Noche Buena, Herradura and San Julián, while silver reserves decreased 5.1% mainly due to San Julián (Veins) and Saucito.

-- 2018 exploration budget of approximately US$140 million (including capitalised exploration expenses)

Board change

-- In view of the demands of his recent appointment as Chairman of BBVA Bancomer, Mr Jaime Serra Puche resigned from the Board on 25th February 2019. The Nominations Committee has begun a search for a new independent non-executive director of the Company.

Outlook

-- Silver production expected to be in the range of 58 to 61 moz including the Silverstream. Gold production expected to be in the range of 910-930 koz

   --      Capital expenditure is anticipated to be approximately US$710 million

About Fresnillo plc

Fresnillo plc is the world's largest primary silver producer and Mexico's largest gold producer, listed on the London and Mexican Stock Exchanges under the symbol FRES.

Fresnillo plc has seven operating mines, all of them in Mexico - Fresnillo, Saucito, Ciénega (including the San Ramón satellite mine), Herradura, Soledad-Dipolos(1) , Noche Buena and San Julián (Phase I and II), one development project - the Pyrites Plant at Fresnillo, and four advanced exploration projects - Orisyvo, Juanicipio, Las Casas Rosario & Cluster Cebollitas and Centauro Deep, as well as a number of other long term exploration prospects. In total, Fresnillo plc has mining concessions covering approximately 1.8 million hectares in Mexico and 700 thousands hectares in Peru.

Fresnillo plc has a strong and long tradition of exploring, mining, a proven track record of mine development, reserve replacement, and production costs in the lowest quartile of the cost curve for silver.

Fresnillo plc's goal is to maintain the Group's position as the world's largest primary silver company and Mexico's largest gold producer.

(1) Operations at Soledad-Dipolos are currently suspended.

CHAIRMAN'S STATEMENT

Celebrating the last ten years, while preparing ourselves for the future

During its first ten years as a plc, Fresnillo has achieved remarkable success. The company has positioned itself as one of the most profitable on the London Stock Exchange (LSE), generating significant benefits for shareholders, local communities and Mexico in general.

Major achievements and milestones over this period include: an 80% increase in silver production and a 230% increase in attributable gold production; four new mining operations and a strong project pipeline based on successful exploration efforts; a 149% growth in employment; investments of over US$135 million in health, safety and training; direct payments of close to US$32 million to support local communities, including primary education of over 8,000 children in 66 schools; more than US$2.3 billion paid in taxes; US$5.0 billion invested in new and existing operations; and over US$2.8 billion of dividends paid to shareholders. Through the support of our workforce and local communities, as well as the introduction of new technologies to improve working conditions, safety and environmental impacts, we are recognised around the globe as a leading and respected public limited company.

It has been a privilege for me to lead the development of Fresnillo from its initial establishment as a LSE listed company to the present day. During those ten years, we have enjoyed high levels of growth and generated high returns consistently across price cycles and through a wide range of economic conditions. At the same time, we have learnt from the challenges encountered along the way, including the shortfall in production at our flagship Fresnillo mine and the delay of a couple of projects, which in turn has made us narrowly miss our long-term silver target of 65 moz despite considerable investments in successful new mines. On the positive side, we surpassed our long-term gold target in 2015 and have continued to build on that achievement over the last three years.

The Board and I continue to place the utmost importance on providing safe and healthy working conditions for our workforce. We are extremely saddened about the five fatalities during the year, as well as a further one in early 2019, and our thoughts are with the families and friends of those concerned. Our response has been to further strengthen our procedures and controls, with the ongoing support of an experienced engineer in charge of safety, health and community issues.

As you will read in the Chief Executive Officer's statement and throughout this report, we are carefully considering the demands and challenges of the coming years and we will invest in initiatives that will enable us to continue to grow and achieve good returns.

Achieving year-on-year growth by remaining true to our principles

Proven and practical, our strategy remained untouched during 2018. The focus on disciplined organic growth and on our four strategic pillars of exploration, development, operations and sustainability, enabled us once again to deliver year-on-year growth, despite silver production failing to meet our guidance and long-term target.

The Group generated over US$2.1 billion in adjusted revenue for the year, flat year on year. Profit during the year decreased, while cash and other liquid funds were US$560.8 million at the year end, a decrease of US$335.2 million over 2017. Debt remained unchanged at US$800 million.

Operational highlights

In summary, gold production had to be revised upwards twice during the year, driven by a better than expected performance in Noche Buena and Saucito. Although silver production was up year-on-year, it failed to reach our targets, despite guidance being lowered twice during the period. This was due to continuing challenges at our main underground silver mines. Production at the Fresnillo and Saucito mines was affected by shortcomings in our geological models and poor contractor performance. The geological models at both mines are being revised and in-fill drilling has been increased, while new contractors have been appointed at Fresnillo. At San Julián, although both phases have been operating above nameplate capacity, production was temporarily impacted by water shortages caused by exceptionally dry weather. This limited access to certain production areas included in the mining plan, and led to the need to process lower grade development ore from the existing stockpiles.

Having been part of Mexico's 500 years of mining history, Fresnillo is clearly here for the long term. The key aspects of our longevity are careful planning, extensive development and preparation, not only for the months ahead but also for the many decades to come. As outlined by the Chief Executive Officer, further investments in infrastructure and technology are set to improve the rate of development and construction of the mining infrastructure to underpin production in future years.

At the same time, the investments made in recent years are beginning to bear fruit, including two major projects commissioned during 2018. The new Pyrite plant - to improve gold and silver recoveries at Fresnillo and Saucito - and the second line of the Dynamic Leaching Plant at Herradura have not been without challenges, but are now contributing to production.

The feasibility study for the Juanicipio project, a joint venture with Mag Silver, was completed in 2018 and the formal approval of the project is expected in due course. We are confident that Juanicipio will become a key project, maintaining our track record of high growth and returns.

San Julián and Juanicipio are proof that our consistent commitment to exploration through the cycles of our industry pays clear long-term dividends for our stakeholders. Although this year's results were mixed, the last ten years have seen a substantial increase in reserves and resources.

During 2018, silver and gold reserves decreased 5.1% and 6.0% respectively. Following the 2018 drilling programmes, total silver resources reduced from 2.3 to 2.2 Boz, while total gold resources increased from 38.5 to 39.1 Moz. Our exploration mining concessions amount to 1.8 million hectares in Mexico, 655,000 hectares in Peru, and 10,000 hectares in two exploration options in Chile.

A committed and talented workforce...

A great company is built by great people, and I'm proud to say that our committed teams - from those working in mines and projects to their colleagues in offices across Mexico, South America and the UK- have again demonstrated their experience, dedication and talent. On behalf of the Board, I would like to thank them sincerely for these efforts.

In common with our industry peers as well as businesses operating in many other sectors, we face significant challenges in ensuring that we have the right calibre of people in the right jobs at the right time. To this end, during 2018 we increased the number and scope of partnerships with leading universities and the top earth science institutions in Mexico to develop new training programmes tailored to our requirements. As a result, we have provided 194 students with first hand practical experience during the year, and 173 are now in full time training.

...led by a skilled and experienced executive team

Our Chief Executive Officer Octavio Alvídrez continues to lead the executive management team with distinction, supported by Chief Financial Officer Mario Arreguín and Vice President of Exploration David Giles.

Our Chief Operating Officer, Roberto Díaz, retired at the beginning of 2019, following eight years of service during which our operations made significant progress and major projects were successfully implemented. On behalf of the Board, I thank Roberto for his outstanding contribution and I am pleased to announce that he has agreed to continue to work with us as an advisor on special projects.

We have recently made three senior appointments, two of which are completely new roles for Fresnillo. Together, these appointments will underpin our commitment to improving our safety record and preparing the Group for the future. Firstly, I would like to welcome Andre Sougarret, as new Chief Operating Officer. He brings great mining experience and knowledge to Fresnillo following a notable career in the mining industry, previously holding important positions in Codelco and as Executive Vice President at Empresa National de Mineria in Chile. At the same time, we have appointed a new Chief Projects Officer who is responsible for development projects, freeing up Andre to focus more on the operations side of the business. Finally, and as mentioned earlier, our top team has also been supplemented by the appointment of a permanent specialist advisor who has responsibility for addressing our health and safety record, which was unacceptable during 2018.

Board activities

The Board supports the executive team by playing an active role in defining the strategy, reviewing progress versus plan and making sure that the business has sufficient flexibility to respond to ever-changing market conditions. As a Group, we work hard to ensure that capital allocation is balanced by growth, shareholder returns, financial strength and flexibility, while maintaining our commitment to sustainability and risk management.

The Board's duties include ensuring the highest standards of corporate governance, as befits a constituent of the FTSE100 Index. We are currently considering the implications of the new version of the UK Corporate Governance Code, which will take effect from 1 January 2019.

During the first half of 2018, our Senior Independent Director Charles Jacobs engaged with institutional investors and others regarding Board composition and membership.

Board members also maintain oversight of our corporate culture, and at Board meetings we receive regular reports from the CEO on our Ethics programme and how our values of Responsibility, Integrity, Trust and Loyalty continue to guide our actions. In addition, our Head of Sustainability provides an annual presentation that gives us greater depth and detail about this matter.

Our culture is well-established and ingrained in all areas of operations. During the year we continued to conduct master classes and deliver online training modules in order to ensure that all our people, whether long-time employees or recent ones, understand the importance that we place on the Group's values. However, we recognise that there remains work to do. Our recent safety record is unacceptable and we are therefore bringing additional focus and resources to drive improvement.

Changes to the Board

Guy Wilson retired from the Board at the 2018 AGM, following ten years of service. Guy was instrumental in establishing and then overseeing the work of the Audit Committee and I thank him unreservedly for his tireless work, constant support and good humour. He has been replaced as Chairman of the Audit Committee by Alberto Tiburcio, who joined the Board and Audit Committee in 2016, bringing with him extensive experience in audit and financial reporting.

During the year, the Board was strengthened by the appointment of Georgina Kessel as an Independent Non-executive Director. Ms Kessel worked in the Mexican government where she served as Secretary of State of the Ministry of Energy from 2006 to 2011. She also chaired the Governing Board of the Federal Electricity Commission and has been president and member of the Board of Directors of Petróleos Mexicanos (PEMEX). She is currently an independent director of Scotiabank and Iberdrola and is a partner at Spectron. The Board now has three female members, demonstrating our continued commitment to gender diversity which sits alongside our insistence that all Board members should also have relevant work experience.

In view of the demands of his recent appointment as Chairman of BBVA Bancomer, Mr Jaime Serra Puche resigned from the Board on 25(th) February 2019. The Nominations Committee has begun a search for a new independent non-executive director of the Company. My Board colleagues and I have greatly valued Jaime Serra Puche's contributions to the Fresnillo board meetings over the past five years. His political insight has been particularly valued and we have been grateful to have someone of his calibre and experience on our Board. We will miss his input greatly but wish him well for the future.

Continuing our dividend policy

Our dividend policy is well-established, consistent and closely aligned with our commitment to create value through growth and returns. In short, each year we aim to pay out 33-50% of profit after tax, while making certain adjustments to exclude non-cash effects in the income statement. We pay dividends in the approximate ratio of one-third as an interim dividend and two-thirds as a final dividend.

Before declaring a dividend, the Board carries out a detailed analysis of the profitability of the business, underlying earnings, capital requirements and cash flows. Our aim is to maintain enough flexibility to be able to react to movements in precious metals prices and seize attractive business opportunities.

We declared an interim dividend of 10.7 US cents per share, with a final dividend of 16.7 US cents per share, bringing the total for the year to 27.4 US cents per share.

Outlook

In the short term, we are likely to experience a lower rate of growth, as we consolidate the progress made since our IPO and implement the necessary investments and initiatives that will advance our pipeline and underpin our future long-term growth.

Political and economic factors, both in Mexico and across the globe, could also impact our performance. For example, the buoyancy of the US domestic economy is attracting some investment that would otherwise have been directed towards our sector, while the China-US trade war as well as issues in South America and Europe are generating an unwelcome degree of uncertainty. In Mexico, we have a new administration and although we are yet to see any firm indication of direction, we are already working closely with the Government.

The Board and I believe that the developments currently underway, and those that will be introduced or extended during 2019, will position us well for the years ahead. In the coming months and to comply with the 2018 UK Corporate Governance Code, we will continue to work towards defining our Company Purpose. This will be a succinct expression of what Fresnillo is and what we stand for - and it will further focus the minds of all our people on our culture and the things we truly value, such as safety.

We have now established a long track record for delivering growth and returns, and our commitment to keeping that reputation remains undimmed. Fresnillo faces the future with confidence.

Chief Executive's statement

CHIEF EXECUTIVE'S STATEMENT

Consolidating our growth, advancing our pipeline

Since the IPO in 2008, we have recorded an excellent set of achievements and over that period built a track record of creating value through growth and returns. Now is the time to consolidate our position while also making sure we continue to fuel our pipeline in order to deliver further growth in the years ahead.

Although it was disappointing not to reach our long-term silver target of 65 moz, we nevertheless look back with pride on the achievements of the last decade, including the fact that we reached our long-term goal for gold three years ahead of target.

We have delivered on the vast majority of the plans we laid out at the time of the IPO, in both financial and non-financial terms. We are now firmly established as the world's largest silver producer, Mexico's largest gold producer and a company that has earned the respect of its employees and local communities as well as of its shareholders.

Now, in the early months of our second decade, it is time to continue to prepare Fresnillo for the many challenges and opportunities that lie ahead.

Consistency, consistency, consistency

Our strategy has remained the same throughout the last ten years, and this will continue to be the case. While other miners may change their stance depending on which way the economic wind is blowing, at Fresnillo we understand that consistent performance can only be delivered by remaining true to a conservative, long-term strategy.

This strategy has and will continue to achieve results across the various price cycles of precious metals. Although Fresnillo plc has only been in existence for a decade, our history stretches back over 125 years. The knowledge and experience gathered over that period is part of Fresnillo's DNA - and it ensures that we always take a long-term view, executing our strategy with consistency in order to manage fluctuations in prices.

Production highlights and price review

In 2008, we set ourselves the target to double annual silver production to 65 moz and to achieve gold production of 750,000 ounces in the decade to the end of 2018. We successfully reached the gold target in 2015 and although we have fallen just short of that ambitious goal, for silver, this period of consolidation will improve our efficiency, strengthen our operational base and ensure that we continue to deliver growth in the years and decades to come.

Silver production did not quite reach the levels we forecast at the start of the year, following lower than expected ore grades at the Fresnillo and Saucito mines, as well as lower throughput at Fresnillo.

Notwithstanding, silver production from our mines increased 7.1% to 58.1 million ounces in 2018 driven mainly by the first full year of production at the San Julián Disseminated ore body and the contribution from the first phase of the new Pyrites plant at Saucito, which more than offset the lower production at the Fresnillo and Saucito mines.

We achieved better than anticipated results for gold in 2018, with production increasing slightly by 1.3% to 922,527 ounces. This reflected a good performance at Saucito, the start-up of the Pyrites plant and higher gold production at Fresnillo.

During the year, average realised silver prices decreased by 8.3%, with those for gold remaining broadly flat (up 0.1%). At the same time, average prices for zinc and lead, which are by-products of our silver and gold operations, decreased by 5.7% and 7.4% respectively and this had an impact on our financial performance.

Consolidating growth, maximising potential

The first pillar of our strategy is to maximise the potential of our existing operations, and during the year we were pleased to launch a series of operational excellence initiatives that will provide the platform for further growth in the years to come.

At the Fresnillo mine, for example, we have invested in innovative technology to improve productivity. Costing US$22.7 million and capable of boring at least 300 metres per month, a new state-of-the-art tunnelling machine is due to be commissioned in 2H19. Together with the vertical conveyor, which was commissioned towards the end of 2017, and the installation of new vibrating screens which have already proved their value at Saucito, the tunnelling machine will support our drive to extract greater value from the long-established Fresnillo mine.

Meanwhile, at San Julián we have addressed the low water availability that limited production during the early months of 2018. In the short term this involved digging wells, but in line with our commitment to always taking a long-term view, we have since successfully concluded consultations with the indigenous population regarding the construction of a new water reservoir which will ensure sufficient water to support greater production at San Julián.

IT is another example of how we are using innovation and new ways of working to improve production while lowering costs. For example, during 2018, we launched or rolled-out a wide range of projects that are already beginning to transform productivity.

Delivering growth through development projects

I fully expect to be able to make a positive announcement on our Juanicipio development project in due course, following a highly detailed technical evaluation that demonstrated its long-term viability. Eight kilometres from the Fresnillo mine, Juanicipio is expected to contribute to both silver and gold production, delivering high returns for our business while generating additional employment in the area. With first production anticipated in 2H20, Juanicipio reaffirms the world-class status of the Fresnillo district and underlines the wealth of resources that have already been discovered there, as well as those that await discovery in the future.

In addition, the first stage of the new Pyrites plant has now been completed and commissioned on budget, with only minor delays. While the ramp up did not accelerate as expected due to issues with the vertical mills, which have now been resolved, the plant will make an important contribution to production by extracting additional quantities of gold and silver from the historical and ongoing tailings at the Fresnillo and Saucito mines. Stage two is now underway and is expected to be concluded in 2H20.

We were also pleased to commission the second line at the Dynamic Leaching Plant (DLP) at Herradura during the year. The testing period took longer than expected and despite production coming from the plant during the year, commercial production did not commence until 2019. Now complete, the DLP is processing an extra 8,000 tonnes per day of high grade ore from the pit, taking the daily throughput for the two DLP plants to 16,000 tonnes. Also at Herradura, tests of the leaching pads led to an increase of 98.9 thousand ounces of gold in inventory.

Extending the growth pipeline

Our approach towards exploration is one of the qualities that sets us apart from our peers. Where they may choose to cut back on exploration in order to meet short-term price challenges, our commitment remains unequivocal and unchanging, regardless of the prevailing economic climate. Rather than opting to boost our pipeline through acquisition, we remain determined to fuel ours organically - drawing on the skills of more than 100 talented geologists to explore opportunities and build our resource base.

Among the year's most significant exploration developments, we continued to make good progress at Orisyvo and Guanajuato, while the project at Rodeo is showing good potential. At the end of 2018, our silver resources stood at 2.2 boz, down by 5.0% over the previous year, with our exploration mining concessions amounting to 1.8 million hectares in Mexico. Our gold resources increased by 1.5% during the year to 39.1 moz.

Furthermore, 2018 saw us take decisive steps in the internationalisation of our Company, with drilling now expected to take place at two projects in Chile that show good potential. We are also working hard to gain the necessary permits in Peru and continuing to scout projects in Argentina.

Advancing and enhancing the sustainability of our operations

The safety of our employees and contractors is our highest priority, and we continually monitor our performance and introduce new initiatives to address any gaps or failings in our processes. So it was both deeply saddening and totally unacceptable that we experienced five fatalities during the year and one more in early 2019. While we acknowledge that contractor safety is a particular challenge for our industry, this performance is clearly unacceptable. The safety of all of our employees and contractors is at the top of our HSECR agenda for 2019, and we will renew our efforts to align employees and contractors alike with our commitment to safety.

As I highlighted in last year's report, we began to roll out a new safety programme during 2018, following encouraging results from the pilot phase at our Fresnillo and Saucito mines. Known as I Care, We Care, this programme builds on and strengthens our existing processes. The key aspect of I Care, We Care is that it encourages people to fully report every incident, no matter how minor, so that our safety team can identify its root cause, develop risk awareness and put measures in place to prevent reoccurrence. The roll out is expected to be completed in 2019.

In terms of environmental sustainability, we passed an important milestone in 2018. Over 60% of the electricity we consume is now provided by wind power - and we aim to increase this to 75% by the second half of 2019. The resultant decrease in our carbon emissions will also be supported by an initiative to convert a number of trucks in our fleet from diesel to Liquid Natural Gas, which will benefit the environment while also reducing our costs.

Our strong environmental, social and governance practices have again been recognised by external organisations. Not only did we retain our place in the FTSE4Good Index, but we also joined the STOXX Global ESG Leaders index for the first time. In addition, we received or retained a large number of national and international awards and certifications including:

-- An Ethics and Values award from the Confederation of Industrial Chambers (Concamin) in Mexico

-- The Social Responsibility Award from the Federal Attorney for Environmental Protection (Profepa) in Mexico

   --      A Profepa Award for Environmental Excellence at Saucito and Herradura 
   --      Clean Industry national certification from Profepa 

-- International certifications including; the Cyanide Code at Herradura and Noche Buena; ISO 14,001 (Environment); and OHSAS 18,001 (Safety and Environment)

The year ahead

We anticipate that 2019 will be a more challenging year than 2018, with a number of industry variables potentially working against us. While the volatility of precious metals prices is likely to reduce, the prices themselves may reduce, for example, and we could see headwinds from higher inflation and possibly a worsening of the US$-Peso exchange rate. The significant investments we have made in recent years will inevitably lead to greater depreciation costs and these will in turn impact our financial performance. In addition, silver and gold production may temporarily reduce, as we invest time and resources in consolidating our past achievements and preparing the ground for greater growth in future years, while also focusing on improved safety.

None of these possible developments are unusual or present us with issues we have not faced before. Change is part of the business cycle. We will continue to stand firm behind our strategy in the clear knowledge that it has guided us through a wide range of market and political conditions in the past, and will do so again in the future.

While we face short-term pressures, the long-term fundamentals remain sound. Our model is proven, our people are skilled, experienced and dedicated, and a track record of creating value through growth and returns will continue to be our defining characteristic.

FINANCIAL REVIEW

The Consolidated Financial Statements of Fresnillo plc are prepared in accordance with International Financial Reporting Standards (IFRS), as adopted by the EU. This Financial Review is intended to convey the main factors affecting performance and to provide a detailed analysis of the financial results in order to enhance understanding of the Group's financial statements. All comparisons refer to 2018 figures compared to 2017, unless otherwise noted. The financial information and year-on-year variations are presented in US dollars, except where indicated.

By following strict controls on cash, costs and expenses and while adhering to our capex budgets, we have maintained a healthy cash and other liquid funds (1) position and a low leverage ratio. This has enabled us to invest in profitable growth and deliver solid returns to shareholders.

The following report presents how we have managed our financial resources.

Commentary on financial performance

2018 was a year of challenges and opportunities for the Group. This was also reflected in the financial performance for the year, with gross profit and EBITDA decreasing over 2017 by 15.6% and 13.7% respectively, while we nevertheless delivered healthy profit margins. We maintained a solid financial position, with US$560.8 million in cash and other liquid funds (1) as of 31 December 2018 notwithstanding paying dividends of US$298.1 million in accordance with our policy, investing US$668.7 million in capex and spending US$172.8 million in exploration to underpin our future growth.

Adjusted revenue slightly increased year-on-year due to the increased volumes of silver, lead and zinc sold, primarily from the San Julián (Disseminated Ore Body), offset by lower prices. This increase, together with the positive effect of the re-assessment of gold content in the leaching pads and the higher ore grade at Herradura, was more than offset by the higher stripping ratio at Herradura and higher depreciation. As a result gross profit decreased 15.6% over 2017 and, together with the higher exploration expenses, this contributed to the 13.7% decline in EBITDA.

The Group's financial performance is largely determined by the quality of our assets, the skills of our people and the execution capabilities of management to achieve our strategic goals. However, there are a number of macroeconomic variables that lie beyond our control and which affect financial results. These include:

Precious metal prices

In 2018, the average realised silver price decreased by 8.3% from US$16.9 per ounce in 2017 to US$15.5 per ounce in 2018. In addition, average realised lead and zinc prices decreased 7.4% and 5.7% year-on-year, to US$0.99 and US$1.28 per pound, respectively. The average realised gold price remained broadly stable at US$1,269.1 per ounce (2017: US$1,267.4).

Hedging

In the second half of 2014, Fresnillo plc initiated a one-off hedging programme to protect the value of the investment made in the Penmont acquisition. The hedging programme was executed for a total volume of 1,559,689 ounces of gold with monthly settlements until December 2019.

The table below illustrates the expired structures and the outstanding hedged position as of 31st December 2018.

*Monthly settlements through December 2019

Fresnillo plc's hedging policy remained unchanged for the remainder of the portfolio, providing shareholders with full exposure to gold and silver prices.

MX$/US$ exchange rate

The average spot Mexican peso/US dollar exchange rate devalued by 1.6%, from $18.94 per US dollar in 2017 to $19.24 per US dollar in 2018. This resulted in a favourable effect estimated at US$6.7 million on the Group's production costs, as costs denominated in Mexican pesos (approximately 45% of total costs) were lower when converted to US dollars.

Hedging

As previously reported, in 2016 Fresnillo plc decided to suspend its Mexican peso exchange rate hedging programme to hedge payment of certain peso denominated production costs. However, the Group has continued to enter into certain exchange rate derivative instruments as part of a programme to manage its exposure to foreign exchange risk associated with the purchase of equipment denominated in Euro (EUR), Swedish krona (SEK) and Canadian dollar (CAD). The aggregate effect on income in the year was a loss of US$321,873 (See foreign exchange section below).

Cost INflation

In 2018, there was a cost inflation of 2.6% net of the 1.6% average devaluation of the Mexican peso against the US dollar. The main components of our cost inflation basket are listed below:

Labour

Unionised employees received on average a 7.0% increase in wages in Mexican pesos, and administrative employees at the mines received a 5.5% increase; when converted to US dollars, the weighted average labour inflation was 4.5%.

Energy

Electricity

The Group's weighted average cost of electricity decreased by 6.4% from US$7.6 cents per kW in 2017 to US$7.1 cents per kW in 2018. This decrease was mainly due to the lower average generating cost of the Comisión Federal de Electricidad (CFE), the national utility.

Diesel

The weighted average cost of diesel in US dollars increased 7.7% to US$82.4 cents per litre in 2018, compared to US$76.5 cents per litre in 2017.

--------------------------------------------  -------- 
Weighted average of all operating materials        1.4 
--------------------------------------------  -------- 
 

Unit prices of the majority of operating materials remained broadly stable in US dollar terms, with the exception being the steel balls for milling and other reagents, which experienced year-on-year inflation of over 5%. However, this was partly offset by the decrease in the unit price of tyres and steel for drilling. As a result, the weighted average unit prices of all operating materials increased by 1.4% over the year. There has been no significant impact on the unit cost of operating materials from the devaluation of the MXN peso/US dollar exchange rate as the majority of these items are dollar-denominated.

Contractors

Agreements are signed individually with each contractor company, and include specific terms and conditions that cover not only labour, but also operating materials, equipment and maintenance, amongst others. Contractor costs are mainly denominated in Mexican pesos and are an important component of our total production costs. In 2018, increases granted to contractors, whose agreements were due for review during the period, resulted in a weighted average increase of 2.9% in US dollars.

Maintenance

Unit prices of spare parts for maintenance remained broadly unchanged on average in US dollar terms (0.7% increase).

Others

Other cost components include freight, which increased by an estimated 7.7% in US dollars, partially offset by a 2.7% decrease in insurance costs. The remaining cost inflation components experienced average inflation of 1.8% in US dollars over 2017.

The effects of the above external factors, combined with the Group's internal variables, are further described below through the main line items of the income statement.

The higher volumes of silver sold resulted from the first complete year of San Julián (Disseminated Ore Body) and the increased production at Herradura and Ciénega, while the higher sales of lead and zinc were mainly driven by the contribution of San Julián (Disseminated Ore Body) and the increased volumes of base metals at depth in the Saucito mine. These favourable effects, net of the lower volume of gold sold, resulted in a positive impact on revenue of US$108.3 million. This was offset by a US$98.2 million negative effect primarily resulting from the lower silver, lead and zinc prices.

The contribution of gold to Adjusted revenue decreased slightly from 50.4% in 2017 to 49.9% in 2018, reflecting the expected lower volumes of gold produced and sold, while silver's contribution to Adjusted revenue decreased to 36.3% as the increased volumes of silver sold were more than offset by the lower price. As expected, the higher content of base metals at certain mines is changing the relative proportion of Adjusted revenue, with zinc increasing its contribution from 7.2% in 2017 to 9.1% in 2018, and lead representing 4.7%.

Herradura remained the main contributor to Adjusted revenue, primarily due to the higher volumes of silver sold during the year. Saucito's and Fresnillo's contribution declined from 22.6% and 18.9% in 2017to 21.9% and 16.9% respectively in 2018, reflecting the decrease in silver ore grade and a lower silver price. The San Julián mine continued to increase its contribution to the Group's Adjusted revenue from 12.9% in 2017 to 16.4% in 2018. Noche Buena's contribution decreased to 9.4%, in line with the 1.9% decline in its Adjusted revenue, while Ciénega maintained its contribution to the Group's Adjusted revenue at 8.3%.

The relative contribution to Adjusted silver revenue continued to change in 2018 with the San Julián mine representing 24.8% (2017: 18.6%), and the contributions of Saucito and Fresnillo decreasing as expected due to an expanded silver asset base.

The start-up of San Julián (Disseminated Ore Body) also affected the relative contribution to zinc adjusted revenues. This new mine represented 25.7% of total zinc Adjusted revenues in 2018, helping to increase zinc's relative contribution to the Group's Adjusted revenues.

The contribution by metal and by mine to Adjusted revenues is expected to change further in the future, as new projects are incorporated into the Group's operations and as precious metal prices fluctuate.

Treatment and refining charges

Treatment and refining charges (3) are reviewed annually using international benchmarks. Treatment charges per tonne of lead and zinc concentrate decreased in dollar terms by 13.3% and 7.5%, respectively, compared to 2017, while silver refining charges declined by 7.4% over the year. This lower charge per tonne was offset by the increase in volumes of lead and zinc concentrates with high silver contents mainly shipped from Saucito and San Julián (Disseminated Ore Body) to Met-Mex, as well as the volumes of precipitates sold from the Pyrites plant. As a result, treatment and refining charges set out in the income statement in absolute terms increased by only 0.9% over 2017.

3 Treatment and refining charges include the cost of treatment and refining as well as the margin charged by the refiner.

4 Adjusted production costs is calculated as total production costs less depreciation, profit sharing and the effects of exchange rate hedging.

Cost of sales increased 13.3% to US$1,323.1 million in 2018. The US$155.2 million increase is explained by the following combination of factors:

-- An increase in Adjusted production costs (+US$182.8 million). This was primarily due to: i) higher stripping costs at Herradura (+US$82.6 million); ii) additional Adjusted production costs associated with the first complete year of operations at San Julián (Disseminated Ore Body) (+US$49.6 million); iii) the decrease in volume of ore processed from development works at Saucito, the costs of which were capitalised (+US$31.2 million); iv) cost inflation (+US$26.4 million); v) the reassessment in the year of the number of mining components at Herradura from two to one, effective from July 2019, which increased stripping costs expensed (+US$21.9 million). The increase was partly offset by the lower volume of ore processed mainly at Herradura (-US$19.6 million); and the favourable effect of the devaluation of the Mexican peso vs US dollar and others (-US$9.3 million).

-- Depreciation (+US$44.2 million). This is mainly due to the full year of operation at San Julián and the increased depreciation at the Saucito mine resulting from the start up of the Pyrites plant and the amortisation of capitalised mining works.

These negative effects were partly offset by:

-- The increase in change in work in progress (-US$70.4 million). Change in work in progress was -US$53.6 million in 2018 as a result of the re-assessment of the gold content in the leaching pads at Herradura (see notes 2c and 5 in the financial information). This compared favourably to the US$16.9 million costs recorded in 2017 as a result of the decrease in inventories in the leaching pads at Herradura.

   --     Others -US$1.3 million. 

Cost per tonne, cash cost per ounce and all-in sustaining cost (AISC)

Cost per tonne is a key indicator to measure the effects of mining inflation and cost control performance at each mine. This indicator is calculated as total production costs, plus ordinary mining rights, less depreciation, profit sharing and exchange rate hedging effects, divided by total tonnage processed. We have included cost per tonne hauled/moved as we believe it is a useful indicator to thoroughly analyse cost performance for the open pit mines.

(5) Indicator may not be representative as it corresponds to the start-up period, when a significant volume of ore from stock pile is processed.

Fresnillo

Cost per tonne increased 4.1% to US$49.4 in 2018 mainly due to: i) cost inflation for this mine of 2.53% (largely related to contractors, personnel and operating materials); and ii) a greater number of contractors for maintenance to solve the problem related to equipment availability.

Saucito

Cost per tonne increased 26.2% to US$60.1, mainly due to: i) lower volume of ore processed from development work; ii) increased in the number of contractors for development works; and iii) higher consumption of reagents. Cost inflation at this mine was 2.45%.

Ciénega

Cost per tonne at Ciénega increased 6.5% to US$70.8 mainly due to the increase in contractors for development and civil works. Cost inflation at this mine was 1.57%.

Herradura

Cost per tonne of ore deposited increased 65.8% to US$13.2 mainly due to: i) higher stripping charged to production costs; ii) the change in criteria from two to one component; and iii) inefficiencies due to lower volume deposited (-14.9%). Cost inflation at this mine was 4.0% (largely related to the increase in the price of diesel).

Noche Buena

Cost per tonne at this mine decreased 9.4% to US$6.8 in 2018 as a result of shorter distances to haul mineral from the pit to the leaching pads, despite the fact that cost inflation at this mine was 2.54% (mainly related to the unit price of diesel).

San Julián (Veins)

Cost per tonne at San Julián (Veins) rose 10.1% mainly due to the increase in the number of contractors for mining works.

Cash cost per ounce, calculated as total cash cost (cost of sales plus treatment and refining charges, less depreciation) less revenue from by-products divided by the silver or gold ounces sold, when compared to the corresponding metal price, is an indicator of the ability of the mine to cover its production costs.

The particular variations in cash cost for each mine are explained as follows:

Fresnillo: US$0.46/oz (2018) versus US$0.71/oz (2017), (-35.2%)

Cash cost per ounce decreased, principally due to higher by-product credits (-US$0.97/oz) and lower treatment charges (-US$0.24/oz), partially offset by the lower silver ore grade (+US$0.71/oz) and the higher cost per tonne (+US$0.28/oz).

Saucito: US$0.97/oz (2018) versus US$1.50/oz (2017), (-35.6%)

The decrease was driven by the higher by-product credits per ounce of silver resulting from the increased volume of gold sold (-US$2.29/oz), partially offset by the higher cost per tonne (+US$1.21/oz) and the lower silver grade (+US$0.55/oz).

Ciénega: US$25.88/oz (2018) versus -US$163.74/oz (2017), (N/A)

The increase in cash cost was primarily due to: the expected decrease in gold grade (+US$115.01/oz), the higher cost per tonne (+US$42.32/oz) and higher treatment and refining charges (+US$6.78/oz). These unfavourable factors were mitigated by higher by-product credits per gold ounce due to the lower volume of gold produced (-US$19.26/oz); and others (-US$3.96/oz).]

Herradura: US$504.00/oz (2018) versus US$492.86/oz (2017), (+2.3%)

The increase in cash cost resulted from the higher cost per tonne (+US$261.13/oz) and the change from two mining components to one during the year (+US$60.68/oz); mitigated by the higher gold grade (-US$247.39/oz); a favourable inventory valuation effect due to the increase in gold inventories on the leaching pads (-US$34.32/oz); and higher by-product credits per gold ounce due to the increased volume of silver sold, albeit at a lower price (-US$29.75/oz).

Noche Buena: US$735.41/oz (2018) versus US$793.48/oz (2017), (-7.3%)

The decrease in cash cost per ounce was mainly due to the lower cost per tonne (-69.41/oz).

San Julián VEINS: -US$3.64/oz (2018) versus -US$4.30/oz (2017), (+15.4%)

The increase in cash cost was explained mainly by the lower silver ore grade (+US$1.29/oz) and higher cost per tonne (+US$0.04/oz), mitigated by lower by-product credits due to the decline in volume of gold sold (-0.67/oz).

San Julián DISSEMINATED ORE BODY: As operations commenced in July 2017, there are no comparable year-on-year figures.

In addition to the traditional cash cost described above, the Group is reporting all-in sustaining costs (AISC), in accordance with the guidelines issued by the World Gold Council.

This cost metric is calculated as traditional cash cost plus on-site general, corporate and administrative costs, community costs related to current operations, capitalised stripping and underground mine development, sustaining capital expenditures and remediation expenses.

We consider all-in sustaining costs to be a reasonable indicator of a mine's ability to generate free cash flow when compared with the corresponding metal price. We also believe it is a means to monitor not only current production costs, but also sustaining costs as it includes mine development costs incurred to prepare the mine for future production, as well as sustaining capex.

1 Indicator may not be representative as it corresponds to the start-up period, when a significant volume of ore from stock pile was processed.

Fresnillo: Higher, mainly due to capitalised mine development mitigated by lower sustaining capex.

Saucito: Higher, as a result of higher capitalised mine development and an increase in sustaining capex.

Ciénega: Higher, primarily due to an increase in sustaining capex, higher capitalised mine development and a higher cash cost.

Herradura: Broadly stable, mainly due to the decrease in capitalised stripping costs following the reassessment of the number of mining components from two to one; offset by higher cash cost detailed above.

Noche Buena: Higher, driven by the higher capitalised stripping, mitigated by the lower cash cost detailed above.

San Julián:

San Julián (Veins): Higher, mainly due to increased sustaining capex and higher capitalised mine development.

San Julián (Disseminated Ore Body): As operations commenced in July 2017, there are no comparable year-on-year figures.

Gross profit

Gross profit, excluding hedging gains and losses, is a key financial indicator of profitability at each business unit and the Fresnillo Group as a whole.

Total gross profit, net of hedging gains and losses, decreased by 15.6% to US$780.7 million in 2018.

The US$144.7 million decrease in gross profit was mainly explained by: i) lower silver, lead and zinc prices (-US$97.7 million); ii) the higher stripping ratio at Herradura (-US$82.6 million); iii) the 17.5% decrease in volume of ore deposited at the Herradura heap leach (-US$64.8 million); iv) higher depreciation (-US$44.2 million); v) the decrease in volume of ore processed from development at Saucito, the costs of which were capitalised (-US$31.2 million); vi) cost inflation (-US$26.4 million); vii) the adverse effect of recognising the entirety of the stripping in the income statement in 2H 2019 following the change from two components to one at Herradura, as opposed to partially capitalising it (-US$21.8 million); viii) lower production at San Julián (Veins) (-US$19.5 million); and ix) others (-US$7.0 million). These factors were partly mitigated by: i) the re-assessment of gold inventories in the leaching pads at Herradura (+US$94.4 million); ii) the higher ore grade from the inventory and improved speed of recovery at Herradura (+US$68.4 million); iii) increased production at San Julián (Disseminated Ore Body) resulting from its first complete year of operations (+US$67.1 million); and iv) the higher recovery rate at Saucito (+US$20.7 million).

As reflected in the table below, Herradura remained the largest contributor to the Group's consolidated gross profit, although there was a slight decrease in its gross profit when compared to 2017. Gross profit at Saucito and Fresnillo declined by 22.1% and 24.5% over 2017 respectively, decreasing its contribution to the consolidated gross profit. San Julián remained the fourth largest contributor. Gross profit at Noche Buena increased 18.1% year on year, providing 8.7% of total gross profit, while Ciénega's share of the Group's total gross profit decreased to 4.1%.

Administrative and corporate expenses

Administrative expenses increased 21.0% from US$42.3 million to US$51.2 million, due mainly to an increase in services provided by consultants (legal, safety, taxes, geological, indigenous community consultation, amongst other).

Corporate expenses increased 5.7% over 2017 to US$32.1 million mainly as a result of increased corporate services provided by Servicios Industriales Peñoles, S.A.B de C.V., due to a larger number of mines and projects, and to a lesser extent, a 2.0% cost inflation.

Exploration expenses increased as planned by 22.5% from US$141.1 million in 2017 to US$172.8 in 2018, due to intensified exploration activities, mainly around our mining districts and advanced exploration projects. An additional US$8.4 million was capitalised, mainly relating to exploration expenses at the Juanicipio project, Centauro Deep and Guanajuato. As a result, risk capital invested in exploration totalled US$181.2 million in 2018, a 24.7% increase over 2017. In 2019, total invested in exploration is expected to be approximately US$140 million, of which US$10 million is expected to be capitalised.

EBITDA is a gauge of the Group's financial performance and a key indicator to measure debt capacity. It is calculated as gross profit plus depreciation, less administrative, selling and exploration expenses. In 2018, EBITDA decreased 13.7% to US$915.1 million mainly due to the lower gross profit. As a result, EBITDA margin expressed as a percentage of revenue decreased, from 50.6% in 2017 to 43.5% in 2018.

Other OPERATING INCOME AND EXPENSE

In 2018, a net gain of US$3.3 million was recognised in the income statement. This compared unfavourably to the US$16.8 million net gain recognised in 2017 mainly as a result of the sale of non-strategic mining claims to Argonaut Gold Inc.

Silverstream effects

The Silverstream contract is accounted for as a derivative financial instrument carried at fair value. The total revaluation effect recorded in the 2018 income statement was a gain of US$15.0 million. This includes negative non-cash revaluation effects of US$22.5 million mainly as a result of the lower forward price of silver and a higher discount rate used, mitigated by the updating of the Sabinas production plan, which resulted from the updated estimate of reserves and resources. This was more than offset by a US$37.5 million non-cash gain mainly generated by the unwinding of the discounted values. In 2017, a US$113.7 million gain was registered mainly as a result of converting resources into reserves at the Sabinas mine.

Since the IPO, cumulative cash received has been US$629.3 million. The Group expects that further unrealised gains or losses will be taken to the income statement in accordance with silver price cyclicality or changes in the variables considered in valuing this contract. Further information related to the Silverstream contract is provided in the balance sheet section and in notes 13 and 29 to the consolidated financial statements.

Finance costs

Finance costs reflected the interest on the US$800 million principal amount of 5.5% Senior Notes, net of interest received. In 2018 finance costs decreased 21.8%, from US$34.0 million to US$29.6 million, mainly due to the decrease in borrowing costs capitalised in 2018 compared to 2017.

In 2018, following the adoption of IFRS 9, Financial Instruments, the effects of the mark-to market time value of the outstanding gold hedging programme are recognised in other comprehensive income, rather than in income as in 2017 (see note 2c in the financial information). This caused a favourable effect as a US$41.1 million loss was recognised in 2017.

Foreign exchange

A foreign exchange loss of US$8.1 million was recorded as a result of the realised transactions in the year. This compared negatively against the US$6.4 million foreign exchange loss recognised in 2017.

The Group enters into certain exchange rate derivative instruments as part of a programme to manage its exposure to foreign exchange risk associated with the purchase of equipment denominated in Euro (EUR), Swedish krona (SEK) and Canadian dollar (CAD). At the end of 2018, the total EUR, SEK and CAD outstanding net forward position was EUR 12.67 million, CAD 0.0 and SEK 13.29 million with maturity dates from March through September 2019. Volumes that expired during 2018 were EUR 26.41 million with a weighted average strike of 1.2024 USD/EUR, CAD 1.10 million with a weighted average strike of 1.2847 CAD/USD and SEK 69.70 million with a weighted average strike of 8.5762 SEK/USD. The aggregate effect on income in the year was a loss of US$321,873.

Taxation

Corporate income tax expense decreased 21.4% from US$153.5 million in 2017 to US$120.6 million in 2018, reflecting the decline in profit before income tax.

The effective tax rate, excluding the special mining rights, was 24.9%, which was below the 30% statutory tax rate. This was mainly due to the inflationary uplift of the tax base of assets and liabilities, together with the tax credit related to the special tax on diesel. Including the effect of the special mining rights, the effective tax rate was 27.7% in 2018.

The effective tax rate in 2017 was lower (20.7% in 2017 vs 24.9% in 2018) mainly because in 2017 there was a 4.5% revaluation of the Mexican peso which had an important impact on the tax value of assets and liabilities that are denominated in Mexican pesos; together with a higher inflation rate which impacted the inflationary uplift of the tax base of assets and liabilities (See note 10 to the financial statements).

Profit for the year

Profit for the year decreased from US$560.8 million to US$350.0 million in 2018, a 37.6% decline year on year as a result of the factors decribed above.

Excluding the effects of the Silverstream Contract, profit for the year decreased from US$481.2 million to US$339.5 million.

   1   Cash and other liquid funds are disclosed in note 31(c) to the financial statements. 

Cash generated by operations before changes in working capital decreased by 13.3% to US$930.7 million, mainly as a result of the lower profits generated in the year. Working capital increased US$127.9 million mainly due to increased ore inventories in the leaching pads at Herradura (US$63.9 million); higher trade and other receivables resulting from an increase in VAT receivables (US$60.4 million); and an increase in prepayments and other assets (US$11.8 million). This increase in working capital was partly offset by an increase in trade and other payables (US$8.2 million).

Taxes and employee profit sharing paid decreased 30.7% over 2017 to US$214.4 million.

As a result of the above factors, net cash from operating activities decreased 22.7% from US$761.5 million in 2017 to US$588.4 million in 2018.

Other sources of cash were the proceeds of the Silverstream Contract of US$36.3 million and capital contributions from minority shareholders in subsidiaries of US$23.6 million.

The above funds were mainly used to purchase property, plant and equipment for a total of US$668.7 million, a 10.6% increase over 2017. Capital expenditures for 2018 are further described below:

Dividends paid to shareholders of the Group in 2018 totalled US$298.1 million, a 26.0% increase over 2017, in line with our dividend policy which includes a consideration of profits generated in the period. The 2018 payment included the final 2017 dividend of US$219.4 million and the 2018 interim dividend paid in September of US$78.8 million.

Net interest of US$15.7 million was paid, mainly reflecting the interest paid in relation with the issuance of the US$800 million principal amount of 5.500% Senior Notes.

The sources and uses of funds described above resulted in a decrease in net cash of US$335.2 million (net decrease in cash and other liquid assets), which combined with the US$896.0 million balance at the beginning of the year resulted in cash and other liquid assets of US$560.8 million at the end of 2018.

Balance sheet

Fresnillo plc continued to maintain a solid financial position with cash and other liquid funds (1) of US$560.8 million as of 31 December 2018, albeit decreasing 37.4% versus December 2017, as explained above.

Inventories increased 23.6% to US$335.0 million mainly as a result of the increase in inventories of gold on the leaching pads at Herradura.

Trade and other receivables increased 14.9% to US$462.0 million mainly as a result of the increase in value added tax recoverable.

The change in the value of the Silverstream derivative from US$538.9 million at the beginning of the year to US$519.1 million as of 31 December 2018 reflects proceeds of US$34.8 million corresponding to 2018 (US$31.4 million in cash and US$3.4 million in receivables) and the Silverstream revaluation effect in the income statement of US$15.0 million.

The net book value of property, plant and equipment was US$2,693.1 million at year end, representing a 10.0% increase over 2017. The US$244.5 million increase was mainly due to the advancement in the development projects; capitalised development works; purchase of additional in-mine equipment; and the construction of leaching pads at Herradura and Noche Buena.

The Group's total equity was US$3,128.3 million as of 31 December 2018, a 2.0% increase over 2017. This was mainly explained by the increase in retained earnings, reflecting the 2017 profit and the net unrealised gains on cash flow hedges.

Dividends

Based on the Group's 2018 performance, the Directors have recommended a final dividend of US$16.7 cents per Ordinary Share, which will be paid on 24 May 2019 to shareholders on the register on 26 April 2018. The dividend will be paid in UK pounds sterling unless shareholders elect to be paid in US dollars. This is in addition to the interim dividend of US$10.7 cents per share amounting to US$78.8 million.

The corporate income tax reform introduced in Mexico in 2014 created a withholding tax obligation of 10% relating to the payment of dividends, including to foreign nationals.

Historically the Company has been making dividend payments out of retained earnings generated before the tax reform came into force and no withholding tax has therefore been applicable. We expect that dividend payments relating to 2019 and future years will attract the withholding obligation. However, foreign shareholders may be able to recover such tax depending on their tax residence and the existence of double taxation agreements.

RISK MANAGEMENT FRAMEWORK

Our risk management framework is based on our belief in the importance of risk awareness across the Group. This framework enables us to identify, assess, prioritise and manage risks in order to deliver the value creation objectives defined in our business model.

Risk management system

Our risk management system is based on risk identification, assessment, prioritisation, mitigation and monitoring processes, which are continually evaluated, improved and enhanced in line with best practice.

In addition to our established risk management activities, our executives, including operations managers, the controllership group, HSECR managers and exploration managers regularly engage in strengthening the effectiveness of our current controls. This supports the executives and the Board in each of their responsibilities.

Within the identification phase of our risk management system, the company also captures emerging risks that could arise as a result of new developments that have a chance of impacting Fresnillo, either at a macro or operational level. Examples of these are new requirements imposed by changes to regulation, including stricter environmental rules, the commissioning of a new project and the use of state of the art underground technology, amongst others.

2018 risk assessment

During our 2018 risk assessment exercise, a team of 135 people evaluated 109 risks across all our operations, advanced projects, exploration offices, and support and corporate areas.

We narrowed down our 109 risks into major risks which are monitored by executive management and the Audit Committee. We then further consolidated these into 12 principal risks which are closely monitored by the Board of Directors.

As part of our bottom-up process, each business unit head determined the perceived level of risk for their individual unit. Executive management then reviewed and challenged each perceived risk level, and compared it to Fresnillo plc's risk universe as a whole. The results of this exercise were used as an additional input to identify the Group's principal risks. We conducted the same risk analysis on advanced projects, detailing the specific risks faced by each project according to their unique characteristics and conditions.

Statement of Directors' responsibilities

The Directors are responsible for preparing the annual report and the Group and parent company financial statements in accordance with applicable United Kingdom law and those International Financial Reporting Standards (IFRS) adopted by the European Union.

The Directors are required to prepare financial statements for each financial year which present a true and fair view of the financial position of the Company and of the Group and the financial performance and cash flows of the Company and of the Group for that period. In preparing those financial statements, the Directors are required to:

-- select suitable accounting policies in accordance with IAS 8: 'Accounting Policies, Changes in Accounting Estimates and Errors' and then apply them consistently;

-- present information, including accounting policies, in a manner that provides relevant, reliable, comparable and understandable information;

-- provide additional disclosures when compliance with the specific requirements in IFRS is insufficient to enable users to understand the impact of particular transactions, other events and conditions on the Company and of the Group's financial position and financial performance;

-- state that the Company and the Group has complied with IFRS, subject to any material departures disclosed and explained in the financial statements; and

-- prepare the accounts on a going concern basis unless, having assessed the ability of the Company and the Group to continue as a going concern, management either intends to liquidate the entity or to cease trading, or have no realistic alternative but to do so.

The Directors are responsible for keeping proper accounting records which disclose with reasonable accuracy at any time the financial position of the Company and of the Group and enable them to ensure that the financial statements comply with the Companies Acts 2006 and Article 4 of the IAS Regulation. They are also responsible for safeguarding the assets of the Company and the Group and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

Under applicable UK law and regulations the Directors are responsible for the preparation of a Directors' report, Directors' remuneration report and corporate governance report that comply with that law and regulations. In addition the Directors are responsible for the maintenance and integrity of the corporate and financial information included on the Company's website. Legislation in the UK governing the preparation and dissemination of financial statements may differ from legislation in other jurisdictions.

Neither the Company nor the Directors accept any liability to any person in relation to the annual financial report except to the extent that such liability could arise under English law. Accordingly, any liability to a person who has demonstrated reliance on any untrue or misleading statement or omission shall be determined in accordance with section 90A and schedule 10A of the Financial Services and Markets Act 2000.

In accordance with provision C.1.1 of the UK Corporate Governance Code, the Directors consider that the Annual Report and Accounts, taken as a whole, is fair, balanced and understandable and provides information to enable shareholders to assess the Company's performance, business model and strategy.

Responsibility statement of the Directors in respect of the annual report and accounts

I confirm on behalf of the Board that to the best of its knowledge:

a) the financial statements, prepared in accordance with International Financial Reporting Standards as adopted by the European Union, give a true and fair view of the assets, liabilities, financial position and profit and loss of the Company and the undertakings included in the consolidation taken as a whole; and

b) the management report (encompassed within the 'Overview', 'Strategic report', 'Performance' and 'Governance' sections) includes a fair review of the development and performance of the business, and the position of the Company and the undertakings included in the consolidation taken as a whole, together with a description of the principal risks and uncertainties that they face.

Signed for and on behalf of the Board

Charles Jacobs

Senior Independent Director

The auditor's report on those financial statements was unqualified and did not contain a statement under section 498 of the Companies Act 2006.

The audited financial statements will be delivered to the Registrar of Companies in due course. The financial information contained in this document does not constitute statutory accounts as defined in section 435 of the Companies Act 2006

2. Significant accounting policies

(a) Basis of preparation and consolidation, and statement of compliance

Basis of preparation and statement of compliance

The Group's consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as adopted by the European Union as they apply to the financial statements of the Group for the years ended 31 December 2018 and 2017, and in accordance with the provisions of the Companies Act 2006.

The consolidated financial statements have been prepared on a historical cost basis, except for trade receivables, derivative financial instruments, equity securities, investment in funds and defined benefit pension scheme assets which have been measured at fair value.

The consolidated financial statements are presented in dollars of the United States of America (US dollars or US$) and all values are rounded to the nearest thousand ($000) except when otherwise indicated.

Basis of consolidation

The consolidated financial statements set out the Group's financial position as of 31 December 2018 and 2017, and the results of operations and cash flows for the years then ended.

Entities that constitute the Group are those enterprises controlled by the Group regardless of the number of shares owned by the Group. The Group controls an entity when the Group is exposed to, or has the right to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Entities are consolidated from the date on which control is transferred to the Group and cease to be consolidated from the date on which control is transferred out of the Group. The Group applies the acquisition method to account for business combinations in accordance with IFRS 3.

All intra-group balances, transactions, income and expenses and profits and losses, including unrealised profits arising from intra-group transactions, have been eliminated on consolidation. Unrealised losses are eliminated in the same way as unrealised gains except that they are only eliminated to the extent that there is no evidence of impairment.

Non-controlling interests in the net assets of consolidated subsidiaries are identified separately from the Group's equity therein. The interest of non-controlling shareholders may be initially measured either at fair value or at the non-controlling interest's proportionate share of the acquiree's identifiable net assets. The choice of measurement basis is made on an acquisition by-acquisition basis. Subsequent to acquisition, non-controlling interests consist of the amount attributed to such interests at initial recognition and the non-controlling interest's share of changes in equity since the date of the combination. Any losses of a subsidiary are attributed to the non-controlling interests even if that results in a deficit balance.

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions - that is, a transaction with the owners in their capacity as owners. The difference between fair value of any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interest are also recorded in equity.

(b) Changes in accounting policies and disclosures

The accounting policies adopted in the preparation of the consolidated financial statements are consistent with those applied in the preparation of the consolidated financial statements for the year ended 31 December 2017, except for the following:

New standards, interpretations and amendments (new standards) adopted by the Group

Financial instruments

On January 1, 2018, the Company adopted IFRS 9, Financial Instruments which replaced IAS 39, Financial Instruments: Recognition and Measurement using the modified retrospective approach, hence, the Group does not restate prior periods. Differences between previous carrying amounts using accounting policies as disclosed in the 2017 ARA and those determined under IFRS 9 at the date of initial application have been included in opening retained earnings.

IFRS 9 provides a revised model for classification and measurement of financial instruments; a single, forward-looking expected loss impairment model; and changes to hedge accounting.

The classification and measurement model for financial assets in IFRS 9 is based on the Group's business models for managing its financial assets and whether the contractual cash flows represent solely payments for principal and interest. Generally, equity instruments are classified and measured as fair value through profit or loss (FVPL). However, in respect of equity instruments that the Group intends to hold for the foreseeable future, IFRS 9 permits the Group to irrevocably elect upon initial recognition or transition to classify those assets as fair value through other comprehensive income (FVOCI). Changes in the fair value of equity instruments elected to be classified as FVOCI are not reclassified to profit or loss in future periods. Most of the requirements in IAS 39 for classification and measurement of financial liabilities were carried forward in IFRS 9.

Long-term financial assets

The adoption of IFRS 9 resulted in certain changes to the classification of financial assets previously classified as available-for-sale financial assets (AFS). The Company designated its investments in quoted equity investments as FVOCI and classified investments in funds as FVPL:

                                                                                                                                                                 1 January 2018          31 December 2017 

(in thousands of US dollars)

Available-for-sale financial assets - 144,856

Debt instruments at fair value through profit or loss

                    19,877                                        - 

Equity instruments at fair value through other comprehensive income

 124,979                                        - 
                                                                                                                                                                       144,856                            144,856 

Upon transition, the balance in the AFS reserve relating to investments in funds was reclassified from accumulated other comprehensive income (OCI) to retained earnings in the amount of US$53.8 million. In addition, the amounts previously recognised in retained earnings related to historical impairment of AFS that are now classified as FVOCI have been reclassified to the FVOCI reserve in the amount of US$6.0 million.

Trade receivables

Under IFRS 9, embedded derivatives are no longer separated from their host contracts. Instead, where embedded derivatives are present, the entire host contract is classified as fair value through profit or loss. For the Group, this change affects the trade receivables that include provisional pricing adjustments. However, it did not result in any change in the carrying amount of those trade receivables.

Impairment

The adoption of the new "expected credit loss" impairment model under IFRS 9, as opposed to an incurred credit loss model under IAS 39, had a negligible impact on the carrying amounts of the Group's financial assets on the transition date given the Group transacts exclusively with organisations with strong credit ratings, has had a negligible historical level of counterparty default and only has a short term period of exposure to credit risk.

Hedging

The new general hedge accounting requirements retain the three types of hedge accounting mechanisms previously available under IAS 39. Under IFRS 9, however, greater flexibility has been introduced to the types of transactions eligible for hedge accounting, specifically broadening the types of instruments that qualify for hedging instruments and the types of risk components of non-financial items that are eligible for hedge accounting. In addition, the effectiveness test has been replaced with the principle of an "economic relationship" and retrospective assessment of hedge effectiveness is no longer required. Enhanced disclosure requirements about an entity's risk management activities have also been introduced.

IFRS 9 changes the accounting requirements for the time value of purchased options where only the intrinsic value of such options has been designated as the hedging instrument. In such cases, changes in the time value of options are initially recognised in OCI as a cost of hedging. Where the hedged item is transaction related, amounts initially recognised in OCI related to the change in the time value of options are reclassified to profit or loss or as a basis adjustment to non-financial assets or liabilities upon maturity of the hedged item, or, in the case of a hedged item that realises over time, the amounts initially recognised in OCI are amortised to profit or loss on a systematic and rational basis over the life of the hedged item. Under IAS 39, the change in time value of options was recorded in the income statement. As at 1 January 2018, the adjustment to reflect the changes in accounting for the time value of such options increased retained earnings and decreased the cost of hedging reserve by US$19.1 million (US$13.4 million net of tax).

Revenue recognition

On January 1, 2018, the Group adopted IFRS 15, Revenue from Contracts with Customers which supersedes IAS 18, Revenue. IFRS 15 establishes a single five-step model framework for determining the nature, amount, timing and uncertainty of revenue and cash flows arising from a contract with a customer. IFRS 15 requires entities to recognize revenue when control of goods or services transfers to the customer whereas the previous standard, IAS 18, required entities to recognize revenue when the risks and rewards of the goods or services transfer to the customer. The Company concluded there is no change in the timing of revenue recognition of its doré, precipitates and concentrate sales under IFRS 15 compared to the previous standard as the point of transfer of risks and rewards of goods and services and transfer of control occur at the same time. Therefore, no adjustment was required to the Group's financial statements.

Revenue associated with the sale of concentrates, precipitates and doré bars is recognized when control of the asset sold is transferred to the customer. Indicators of control transferring include an unconditional obligation to pay, legal title, physical possession, transfer of risk and rewards and customer acceptance. This generally occurs when the goods are delivered to the customer's smelter or refinery agreed with the buyer; at which point the buyer controls the goods.

The Group's sales contracts, in general, provide for a provisional payment based upon provisional assays and quoted metal prices. Revenues are recorded under these contracts at the time control passes to the buyer and measured at the fair value of the consideration receivable based on forward market prices set on specified quotational periods applied to the Group's best estimate of contained metal quantities.

At each reporting date, provisionally priced metal is marked to market based on the forward selling price for the quotational period stipulated in the contract, changes in fair value of provisionally priced metal is recognised in revenue adjusting the value of sales. The transaction price can be measured reliably as an active and freely traded commodity market such as the London Metals Exchange exists for silver, gold, zinc and lead and the value of product sold by the Company is directly linked to the form in which it is traded on that market. Variations between the price recorded at the date when control is transferred to the buyer and the actual final price set under the smelting contracts are caused by changes in metal prices resulting in the receivable being recorded at FVPL.

Final settlement is based on quantities adjusted as required following the inspection of the product by the customer as well as applicable commodity prices. IFRS 15 requires that variable consideration should only be recognized to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Group concluded that the adjustments relating to the final assay results for the quantity and quality of concentrate sold are not significant and do not constrain the recognition of revenue.

Refining and treatment charges under the sales contracts continue to be deducted from revenue from sales of concentrates as these are not related to a distinct good or service.

Other Narrow Scope Amendments

The Group has adopted IFRIC 22 - Foreign Currency Transactions and Advance Considerations, which did not have a material impact on the Group's consolidated financial statements.

Other than the amendment mentioned above, there were no significant new standards that the Group was required to adopt effective from 1 January 2018.

Standards, interpretations and amendments issued but not yet effective

The standards and interpretations that are issued, but not yet effective, up to the date of issuance of the Group's financial statements are disclosed below. The Group intends to adopt these standards, as applicable to the Group's financial statements, when they become effective, except where indicated.

IFRS 16 Leases

IFRS 16 introduces a single lessee accounting model and requires a lessee to recognise assets and liabilities for all leases with a term of more than 12 months, unless the underlying asset is of low value. A lessee is required to recognise a right-of-use asset representing its right to use the underlying leased asset and a lease liability representing its obligation to make lease payments. IFRS 16 substantially carries forward the lessor accounting requirements in IAS 17. Accordingly, a lessor continues to classify its leases as operating leases or finance leases, and to account for those two types of leases differently. These amendments are effective for annual periods beginning on or after 1 January 2019 and earlier application is permitted. The Group has elected to adopt the new standard from 1 January 2019 applying the simplified transition approach and will not restate comparative amounts for the year prior to first adoption. Right-of-use assets will be measured at the amount of the lease liability on adoption. The Group has set up a project team which has reviewed all of the Group's leasing arrangements over the last year in light of the new lease accounting rules in IFRS 16. As at the reporting date, the Group has non-cancellable operating lease commitments of $16.1 million, see note 24. Of these commitments, approximately $0.2 million relate to short-term leases and $2.7 million to low value leases which will both be recognised on a straight-line basis as expense in profit or loss.

IFRIC 23 Uncertainty over Income Tax treatments

This Interpretation clarifies how to apply the recognition and measurement requirements in IAS 12 when there is uncertainty over income tax treatments. The interpretation is to be applied to the determination of taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and tax rates, when there is uncertainty over income tax treatments. Application of tax law can be complex and requires judgement to assess risk and estimate outcomes where the amount of tax payable or recoverable is uncertain. The Group evaluated potential uncertain tax positions under the requirements of the Interpretation and has not identified any impact on the Group's financial statements. IFRIC 23 is applicable for annual periods beginning on or after 1 January 2019.

The IASB and IFRS Interpretation committee have issued other amendments resulting from improvements to IFRSs that management considers do not have any impact on the accounting policies, financial position or performance of the Group. The Group has not early adopted any standard, interpretation or amendment that was issued but is not yet effective.

(c) Significant accounting judgments, estimates and assumptions

The preparation of the Group's consolidated financial statements in conformity with IFRS requires management to make judgements, estimates and assumptions that affect the reported amounts of assets, liabilities and contingent liabilities at the date of the consolidated financial statements and reported amounts of revenues and expenses during the reporting period. These judgements and estimates are based on management's best knowledge of the relevant facts and circumstances, with regard to prior experience, but actual results may differ from the amounts included in the consolidated financial statements. Information about such judgements and estimates is contained in the accounting policies and/or the notes to the consolidated financial statements.

Judgements

Areas of judgement, apart from those involving estimations, that have the most significant effect on the amounts recognised in the consolidated financial statements for the year ended 31 December 2018 are:

   -      Stripping costs, note 2(e): 

The Group incurs waste removal costs (stripping costs) during the development and production phases of its surface mining operations. During the production phase, stripping costs (production stripping costs) can be incurred both in relation to the production of inventory in that period and the creation of improved access and mining flexibility in relation to ore to be mined in the future. The former are included as part of the costs of inventory, while the latter are capitalised as a stripping activity asset, where certain criteria are met.

Once the Group has identified production stripping for a surface mining operation, judgment is required in identifying the separate components of the ore bodies for that operation, to which stripping costs should be allocated. Generally, a component will be a subset of the total ore body that is made more accessible as a result of the stripping activity. In identifying components of the ore body, the Group works closely with the mining operations personnel to analyse each of the mine plans since components are usually identified during the mine planning stage. The Group reassesses the components of ore bodies in line with the preparation and update of mine plans which usually depend on newest information of reserves and resources.

In the current year, this reassessment did not give rise to any changes in the identification of components except for those existing at Centauro pit at Herradura mine.

Following the results of reserves and resources studies in the prior year, significant additional gold reserves were identified at Centauro pit. The mining operations worked on assessing the impact of these new reserves on the design of the mine and proposed a new mine plan which was approved in July 2018.The new design significantly expands the size of the Centauro pit and results in areas which were previously going to be mined as two separate components being accessed and mined as a single component. Based on the new mine plan, effective 1 July 2018 the Group has changed the components identified at Centuaro pit and therefore the measurement of the corresponding stripping costs.

This change was incorporated prospectively from 1 July 2018. Had the determination of components not changed, capitalised stripping cost during the six-month period ended 31 December 2018 would have been US$28.6 million higher, with an offsetting impact against the work-in-progress inventory balance as of 31 December 2018.

   -      Contingencies, note 25 

By their nature, contingencies will be resolved only when one or more uncertain future events occur or fail to occur. The assessment of the existence and potential quantum of contingencies inherently involves the exercise of significant judgement and the use of estimates regarding the outcome of future events.

Estimates and assumptions

Significant areas of estimation uncertainty considered by management in preparing the consolidated financial statements include:

   -      Estimated recoverable ore reserves and mineral resources, note 2(e): 

Ore reserves are estimates of the amount of ore that can be economically and legally extracted from the Group's mining properties; mineral resources are an identified mineral occurrence with reasonable prospects for eventual economic extraction. The Group estimates its ore reserves and mineral resources based on information compiled by appropriately qualified persons relating to the geological and technical data on the size, depth, shape and grade of the ore body and suitable production techniques and recovery rates, in conformity with the Joint Ore Reserves Committee (JORC) code 2012. Such an analysis requires complex geological judgements to interpret the data. The estimation of recoverable ore reserves and mineral resources is based upon factors such as geological assumptions and judgements made in estimating the size and grade of the ore body, estimates of commodity prices, foreign exchange rates, future capital requirements and production costs.

As additional geological information is produced during the operation of a mine, the economic assumptions used and the estimates of ore reserves and mineral resources may change. Such changes may impact the Group's reported balance sheet and income statement including:

-- The carrying value of property, plant and equipment and mining properties may be affected due to changes in estimated future cash flows, which consider both ore reserves and mineral resources;

-- Depreciation and amortisation charges in the income statement may change where such charges are determined using the unit-of-production method based on ore reserves;

-- Stripping costs capitalised in the balance sheet, either as part of mine properties or inventory, or charged to profit or loss may change due to changes in stripping ratios;

-- Provisions for mine closure costs may change where changes to the ore reserve and resources estimates affect expectations about when such activities will occur;

-- The recognition and carrying value of deferred income tax assets may change due to changes regarding the existence of such assets and in estimates of the likely recovery of such assets.

   -      Estimate of recoverable ore on leaching pads 

In the Group's open pit mines, certain mined ore is placed on leaching pads where a solution is applied to the surface of the heap to dissolve the gold and enable extraction. The determination of the amount of recoverable gold requires estimation with consideration of the quantities of ore placed on the pads and the grade of that ore (based on assay data) and the estimated recovery percentage (based on metallurgical studies and current technology).

The grades of ore placed on pads are regularly compared to the quantities of metal recovered through the leaching process to evaluate the appropriateness of the estimated recovery (metallurgical balancing). The Group monitors the results of the metallurgical balancing process and recovery estimates are refined based on actual results over time and when new information becomes available.

In 2017, the Group decided that it would construct a new leaching pad in a separate area of the Herradura mine. To reduce the hauling distance from the pit to the new pad, the Group constructed an access route through certain existing leaching pads, removing and redepositing the ore in the process. These works allowed the Group to perform assays and verify certain characteristics of the ore, including the humidity of the ore deposited and the grade of gold in solution. The Group finalised the evaluation of those assays during first half of 2018.

As a result of this new information, the Group updated its estimate of the remaining gold content in leaching pads resulting in an increase of 98.9 thousand ounces of gold as at 1 January 2018. This represents 1.7% of the total gold content deposited from the inception of the mine to 31 December 2017.

This change in estimation was incorporated prospectively in inventory from 1 January 2018. The increase in the number of ounces reduced the weighted average cost of inventory. Had the estimation not changed, production cost during the year ended 31 December 2018 would have been US$71.9 million higher, with an offsetting impact against the work-in-progress inventory balance as of 31 December 2018.

   -      Silverstream, note 13: 

The valuation of the Silverstream contract as a derivative financial instrument requires estimation by management. The term of the derivative is based on the Sabinas life of mine and the value of this derivative is determined using a number of estimates, including the estimated recoverable ore reserves and mineral resources and future production profile of the Sabinas mine, the estimated recoveries of silver from ore mined, estimates of the future price of silver and the discount rate used to discount future cash flows. For further detail on the inputs that have a significant effect on the fair value of this derivative, see note 30. The impact of changes in silver price assumptions, foreign exchange, inflation and the discount rate is included in note 31.

   -      Estimation of the mine closure costs, notes 2 (j) and 19: 

Significant estimates and assumptions are made in determining the provision for mine closure cost as there are numerous factors that will affect the ultimate amounts payable. These factors include estimates of the extent and costs of rehabilitation activities, the currency in which the cost will be incurred, technological changes, regulatory changes, cost increases, mine life and changes in discount rates. Those uncertainties may result in future actual expenditure differing from the amounts currently provided. The provision at the balance sheet date represents management's best estimate of the present value of the future closure costs required.

   -      Income tax, notes 2 (q) and 10: 

The recognition of deferred tax assets, including those arising from un-utilised tax losses require management to assess the likelihood that the Group will generate taxable earnings in future periods, in order to utilise recognised deferred tax assets. Estimates of future taxable income are based on forecast cash flows from operations and the application of existing tax laws in each jurisdiction. To the extent that future cash flows and taxable income differ significantly from estimates, the ability of the Group to realise the net deferred tax assets recorded at the balance sheet date could be impacted.

(d) Foreign currency translation

The Group's consolidated financial statements are presented in US dollars, which is the parent company's functional currency. The functional currency for each entity in the Group is determined by the currency of the primary economic environment in which it operates. The determination of functional currency requires management judgement, particularly where there may be more than one currency in which transactions are undertaken and which impact the economic environment in which the entity operates. For all operating entities, this is US dollars.

Transactions denominated in currencies other than the functional currency of the entity are translated at the exchange rate ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are re-translated at the rate of exchange ruling at the balance sheet date. All differences that arise are recorded in the income statement. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates as at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated into US dollars using the exchange rate at the date when the fair value is determined.

For entities with functional currencies other than US dollars as at the reporting date, assets and liabilities are translated into the reporting currency of the Group by applying the exchange rate at the balance sheet date and the income statement is translated at the average exchange rate for the year. The resulting difference on exchange is included as a cumulative translation adjustment in other comprehensive income. On disposal of an entity, the deferred cumulative amount recognised in other comprehensive income relating to that operation is recognised in the income statement.

(e) Property, plant and equipment

Property, plant and equipment is stated at cost less accumulated depreciation and impairment, if any. Cost comprises the purchase price and any costs directly attributable to bringing the asset into working condition for its intended use. The cost of self-constructed assets includes the cost of materials, direct labour and an appropriate proportion of production overheads.

The cost less the residual value of each item of property, plant and equipment is depreciated over its useful life. Each item's estimated useful life has been assessed with regard to both its own physical life limitations and the present assessment of economically recoverable reserves of the mine property at which the item is located. Estimates of remaining useful lives are made on a regular basis for all mine buildings, machinery and equipment, with annual reassessments for major items. Depreciation is charged to cost of sales on a unit-of-production (UOP) basis for mine buildings and installations, plant and equipment used in the mine production process or on a straight-line basis over the estimated useful life of the individual asset when not related to the mine production process. Changes in estimates, which mainly affect unit-of-production calculations, are accounted for prospectively. Depreciation commences when assets are available for use. Land is not depreciated.

The expected useful lives are as follows:

 
                                               Years 
--------------------------------------------  ------ 
 Buildings                                       6 
                                              ------ 
 Plant and equipment                             4 
                                              ------ 
 Mining properties and development costs(1)     16 
 Other assets                                    3 
--------------------------------------------  ------ 
 

(1 Depreciation of mining properties and development cost are determined using the unit-of-production method.)

An item of property, plant and equipment is de-recognised upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising at de-recognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the income statement in the year that the asset is de-recognised.

Non-current assets or disposal groups are classified as held for sale when it is expected that the carrying amount of the asset will be recovered principally through sale rather than through continuing use. Assets are not depreciated when classified as held for sale.

Disposal of assets

Gains or losses from the disposal of assets are recognised in the income statement when all significant risks and rewards of ownership are transferred to the customer, usually when title has been passed.

Mining properties and development costs

Payments for mining concessions are expensed during the exploration phase of a prospect and capitalised during the development of the project when incurred.

Purchased rights to ore reserves and mineral resources are recognised as assets at their cost of acquisition or at fair value if purchased as part of a business combination.

Mining concessions, when capitalised, are amortised on a straight-line basis over the period of time in which benefits are expected to be obtained from that specific concession.

Mine development costs are capitalised as part of property, plant and equipment. Mine development activities commence once a feasibility study has been performed for the specific project. When an exploration prospect has entered into the advanced exploration phase and sufficient evidence of the probability of the existence of economically recoverable minerals has been obtained pre-operative expenses relating to mine preparation works are also capitalised as a mine development cost.

The initial cost of a mining property comprises its construction cost, any costs directly attributable to bringing the mining property into operation, the initial estimate of the provision for mine closure cost, and, for qualifying assets, borrowing costs. The Group cease the capitalisation of borrowing cost when the physical construction of the asset is complete and is ready for its intended use.

Revenues from metals recovered from ore mined in the mine development phase, prior to commercial production, are credited to mining properties and development costs. Upon commencement of production, capitalised expenditure is depreciated using the unit-of-production method based on the estimated economically proven and probable reserves to which they relate.

Mining properties and mine development are stated at cost, less accumulated depreciation and impairment in value, if any.

Construction in progress

Assets in the course of construction are capitalised as a separate component of property, plant and equipment. On completion, the cost of construction is transferred to the appropriate category of property, plant and equipment. The cost of construction in progress is not depreciated.

Subsequent expenditures

All subsequent expenditure on property, plant and equipment is capitalised if it meets the recognition criteria, and the carrying amount of those parts that are replaced, is de-recognised. All other expenditure including repairs and maintenance expenditure is recognised in the income statement as incurred.

Stripping costs

In a surface mine operation, it is necessary to remove overburden and other waste material in order to gain access to the ore bodies (stripping activity). During development and pre-production phases, the stripping activity costs are capitalised as part of the initial cost of development and construction of the mine (the stripping activity asset) and charged as depreciation or depletion to cost of sales, in the income statement, based on the mine's units of production once commercial operations begin.

Removal of waste material normally continues throughout the life of a surface mine. At the time that saleable material begins to be extracted from the surface mine the activity is referred to as production stripping.

Production stripping cost is capitalised only if the following criteria is met:

-- It is probable that the future economic benefits (improved access to an ore body) associated with the stripping activity will flow to the Group;

   --      The Group can identify the component of an ore body for which access has been improved; and 
   --      The costs relating to the improved access to that component can be measured reliably. 

If not all of the criteria are met, the production stripping costs are charged to the income statement as operating costs as they are incurred.

Stripping activity costs associated with such development activities are capitalised into existing mining development assets, as mining properties and development cost, within property, plant and equipment, using a measure that considers the volume of waste extracted compared with expected volume, for a given volume of ore production. This measure is known as "component stripping ratio", which is revised annually in accordance with the mine plan. The amount capitalised is subsequently depreciated over the expected useful life of the identified component of the ore body related to the stripping activity asset, by using the units of production method. The identification of components and the expected useful lives of those components are evaluated as new information of reserves and resources is available. Depreciation is recognised as cost of sales in the income statement.

The capitalised stripping activity asset is carried at cost less accumulated depletion/depreciation, less impairment, if any. Cost includes the accumulation of costs directly incurred to perform the stripping activity that improves access to the identified component of ore, plus an allocation of directly attributable overhead costs. The costs associated with incidental operations are excluded from the cost of the stripping activity asset.

(f) Impairment of non-financial assets

The carrying amounts of non-financial assets are reviewed for impairment if events or changes in circumstances indicate that the carrying value may not be recoverable. At each reporting date, an assessment is made to determine whether there are any indications of impairment. If there are indicators of impairment, an exercise is undertaken to determine whether carrying values are in excess of their recoverable amount. Such reviews are undertaken on an asset by asset basis, except where such assets do not generate cash flows independent of those from other assets or groups of assets, and then the review is undertaken at the cash generating unit level.

If the carrying amount of an asset or its cash generating unit exceeds the recoverable amount, a provision is recorded to reflect the asset at the recoverable amount in the balance sheet. Impairment losses are recognised in the income statement.

The recoverable amount of an asset

The recoverable amount of an asset is the greater of its value in use and fair value less costs of disposal. In assessing value in use, estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. Fair value less cost of disposal is based on an estimate of the amount that the Group may obtain in an orderly sale transaction between market participants. For an asset that does not generate cash inflows largely independently of those from other assets, or groups of assets, the recoverable amount is determined for the cash generating unit to which the asset belongs. The Group's cash generating units are the smallest identifiable groups of assets that generate cash inflows that are largely independent of the cash inflows from other assets or groups of assets.

Reversal of impairment

An assessment is made each reporting date as to whether there is any indication that previously recognised impairment losses may no longer exist or may have decreased. If such an indication exists, the Group makes an estimate of the recoverable amount. A previously recognised impairment loss is reversed only if there has been a change in estimates used to determine the asset's recoverable amount since the impairment loss was recognised. If that is the case, the carrying amount of the asset is increased to the recoverable amount. That increased amount cannot exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognised in previous years. Such impairment loss reversal is recognised in the income statement.

(g) Financial assets and liabilities

From 1 January 2018, the Group classifies its financial assets in the following measurement categories:

   --      those to be measured at amortised cost. 
   --      those to be measured subsequently at fair value through OCI, and. 
   --      those to be measured subsequently at fair value through profit or loss. 

The classification depends on the Group's business model for managing the financial assets and the contractual terms of the cash flows.

For assets measured at fair value, gains and losses will either be recorded in profit or loss or OCI. For investments in equity instruments that are not held for trading, this will depend on whether the group has made an irrevocable election at the time of initial recognition to account for the equity investment at fair value through other comprehensive income (FVOCI).

The group reclassifies debt investments when and only when its business model for managing those assets changes.

Regular way purchases and sales of financial assets are recognised on trade-date, the date on which the Group commits to purchase or sell the asset.

At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss (FVPL), transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVPL are expensed in profit or loss.

Financial assets with embedded derivatives are considered in their entirety when determining whether their cash flows are solely payment of principal and interest.

Subsequent measurement of debt instruments depends on the Group's business model for managing the asset and the cash flow characteristics of the asset. There are three measurement categories into which the Group classifies its debt instruments:

Amortised cost

Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortised cost. Interest income from these financial assets is included in finance income using the effective interest rate method. Any gain or loss arising on derecognition is recognised directly in profit or loss and presented in other gains/(losses) together with foreign exchange gains and losses. Impairment losses are presented as separate line item in the statement of profit or loss.

The Group's financial assets at amortised cost include receivables (other than trade receivables which are measured at fair value through profit and loss).

Fair value through other comprehensive income

Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets' cash flows represent solely payments of principal and interest, are measured at FVOCI. Movements in the carrying amount are taken through OCI, except for the recognition of impairment gains or losses, interest income and foreign exchange gains and losses which are recognised in profit or loss. When the financial asset is derecognised, the cumulative gain or loss previously recognised in OCI is reclassified from equity to profit or loss and recognised in other gains/(losses). Interest income from these financial assets is included in finance income using the effective interest rate method. Foreign exchange gains and losses are presented in other gains/(losses) and impairment expenses are presented as separate line item in the statement of profit or loss.

At transition to IFRS 9, the Group had certain financial asset that were accounted for as debt instruments at fair value through other comprehensive income; however, at the reporting date, no such assets existed.

Equity instruments designated as fair value through other comprehensive income

Upon initial recognition, the Group can elect to classify irrevocably its equity investments as equity instruments designated at fair value through OCI when they meet the definition of equity under IAS 32 Financial Instruments: Presentation and are not held for trading. The classification is determined on an instrument-by-instrument basis.

Gains and losses on these financial assets are never recycled to profit or loss. Dividends are recognised as other income in the statement of profit or loss when the right of payment has been established, except when the Group benefits from such proceeds as a recovery of part of the cost of the financial asset, in which case, such gains are recorded in OCI. Equity instruments designated at fair value through OCI are not subject to impairment assessment.

The Group elected to classify irrevocably its listed equity investments under this category.

Fair value through profit or loss

Assets that do not meet the criteria for amortised cost or FVOCI are measured at FVPL. A gain or loss on a debt investment that is subsequently measured at FVPL is recognised in profit or loss and presented net within other gains/(losses) in the period in which it arises.

Changes in the fair value of financial assets at FVPL are recognised in other gains/(losses) in the statement of profit or loss as applicable.

The Group's trade receivables and derivative financial instruments, including the Silverstream contract, are classified as fair value through profit or loss.

De-recognition of financial assets

Financial assets are derecognised when the rights to receive cash flows from the financial assets have expired or have been transferred and the Group has transferred substantially all the risks and rewards of ownership.

Impairment of financial assets

From 1 January 2018, the Group assesses on a forward looking basis the expected credit losses associated with its debt instruments carried at amortised cost and FVOCI. The impairment methodology applied depends on whether there has been a significant increase in credit risk.

For receivables (other than trade receivables which are measured at FVPL), the Group applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognised from initial recognition of the receivables.

(h) Inventories

Finished goods, work in progress and ore stockpile inventories are measured at the lower of cost and net realisable value. Cost is determined using the weighted average cost method based on cost of production which excludes borrowing costs.

For this purpose, the costs of production include:

- personnel expenses, which include employee profit sharing, materials and contractor expenses which are directly attributable to the extraction and processing of ore;

- the depreciation of property, plant and equipment used in the extraction and processing of ore; and

   -      related production overheads (based on normal operating capacity). 

Operating materials and spare parts are valued at the lower of cost or net realisable value. An allowance for obsolete and slow-moving inventories is determined by reference to specific items of stock. A regular review is undertaken by management to determine the extent of such an allowance.

Net realisable value is the estimated selling price in the ordinary course of business less any further costs expected to be incurred to completion and disposal.

(i) Cash and cash equivalents

For the purposes of the balance sheet, cash and cash equivalents comprise cash at bank, cash on hand and short-term deposits held with banks that are readily convertible into known amounts of cash and which are subject to insignificant risk of changes in value. Short-term deposits earn interest at the respective short-term deposit rates between one day and four months. For the purposes of the cash flow statement, cash and cash equivalents as defined above are shown net of outstanding bank overdrafts.

(j) Provisions

Mine closure cost

A provision for mine closure cost is made in respect of the estimated future costs of closure, restoration and for environmental rehabilitation costs (which include the dismantling and demolition of infrastructure, removal of residual materials and remediation of disturbed areas) based on a mine closure plan, in the accounting period when the related environmental disturbance occurs. The provision is discounted and the unwinding of the discount is included within finance costs. At the time of establishing the provision, a corresponding asset is capitalised where it gives rise to a future economic benefit and is depreciated over future production from the mine to which it relates. The provision is reviewed on an annual basis by the Group for changes in cost estimates, discount rates or life of operations. Changes to estimated future costs are recognised in the balance sheet by adjusting the mine closure cost liability and the related asset originally recognised. If, for mature mines, the revised mine assets net of mine closure cost provisions exceed the recoverable value, the portion of the increase is charged directly as an expense. For closed sites, changes to estimated costs are recognised immediately in profit or loss.

(k) Employee benefits

The Group operates the following plans:

Defined benefit pension plan

This funded plan is based on each employee's earnings and years of service. This plan was open to all employees in Mexico until it was closed to new entrants on 1 July 2007. The plan is denominated in Mexican Pesos. For members as at 30 June 2007, benefits were frozen at that date subject to indexation with reference to the Mexican National Consumer Price Index (NCPI).

The cost of providing benefits under the defined benefit plan is determined using the projected unit credit actuarial valuation method and prepared by an external actuarial firm as at each year-end balance sheet date. The discount rate is the yield on bonds that have maturity dates approximating the terms of the Group's obligations and that are denominated in the same currency in which the benefits are expected to be paid. Actuarial gains or losses are recognised in OCI and permanently excluded from profit or loss.

Past service costs are recognised as an expense on a straight-line basis over the average period until the benefits become vested. If the benefits have already vested following the introduction of, or changes to, a pension plan, the past service cost is recognised immediately.

The defined benefit asset or liability comprises the present value of the defined benefit obligation less the fair value of plan assets out of which the obligations are to be settled directly. The value of any asset is restricted to the present value of any economic benefits available in the form of refunds from the plan or reductions in the future contributions to the plan.

Net interest cost is recognised in finance cost and return on plan assets (other than amounts reflected in net interest cost) is recognised in OCI and permanently excluded from profit or loss.

Defined contribution pension plan

A defined contribution plan is a post-employment benefit plan under which the Group pays fixed contributions into a separate entity and has no legal or constructive obligation to pay further amounts. Obligations for contributions to defined contribution pension plans are recognised as an employee benefit expense in profit or loss when they are due. The contributions are based on the employee's salary.

This plan started on 1 July 2007 and it is voluntary for all employees to join this scheme.

Seniority premium for voluntary separation

This unfunded plan corresponds to an additional payment over the legal seniority premium equivalent to approximately 12 days of salary per year for those unionised workers who have more than 15 years of service. Non-unionised employees with more than 15 years of service have the right to a payment equivalent to 12 days for each year of service. For both cases, the payment is based on the legal current minimum salary.

The cost of providing benefits for the seniority premium for voluntary separation is determined using the projected unit credit actuarial valuation method and prepared by an external actuarial firm as at each year-end balance sheet date. Actuarial gains or losses are recognised as income or expense in the period in which they occur.

Other

Benefits for death and disability are covered through insurance policies.

Termination payments for involuntary retirement (dismissals) are charged to the income statement, when incurred.

(l) Employee profit sharing

In accordance with the Mexican legislation, companies in Mexico are subject to pay for employee profit sharing ('PTU') equivalent to ten percent of the taxable income of each fiscal year.

PTU is accounted for as employee benefits and is calculated based on the services rendered by employees during the year, considering their most recent salaries. The liability is recognised as it accrues and is charged to the income statement. PTU, paid in each fiscal year, is considered deductible for income tax purposes.

(m) Leases

The determination of whether an arrangement is, or contains a lease is based on the substance of the arrangement at inception date including whether the fulfilment of the arrangement is dependent on the use of a specific asset or assets or the arrangement conveys a right to use the asset. A reassessment is made after inception of the lease only if one of the following applies:

a) There is a change in contractual terms, other than a renewal or extension of the arrangement;

b) A renewal option is exercised or extension granted, unless the term of the renewal or extension was initially included in the lease term;

c) There is a change in the determination of whether fulfilment is dependent on a specified asset; or

d) There is a substantial change to the asset.

Group as a lessee

Finance leases which transfer to the Group substantially all the risks and benefits incidental to ownership of the leased item, are capitalised at the inception of the lease at the fair value of the leased asset, or if lower, at the present value of the minimum lease payments. Lease payments are apportioned between the finance charges and reduction of the lease liability so as to achieve a constant rate of interest on the remaining balance of the liability. Finance charges are reflected in the income statement.

Capitalised leased assets are depreciated over the shorter of the estimated useful life of the asset and the lease term, if there is no reasonable certainty that the Group will obtain ownership by the end of the lease term.

Operating lease payments are recognised as an expense in the income statement on a straight-line basis over the lease term.

Group as a lessor

Leases where the Group does not transfer substantially all the risks and benefits of ownership of the asset are classified as operating leases. Initial direct costs incurred in negotiating an operating lease are added to the carrying amount of the leased asset and recognised over the lease term on the same basis as rental income. Contingent rents are recognised as revenue in the period in which they are earned.

Where a reassessment is made, lease accounting commences or ceases from the date when the change in circumstances gave rise to the reassessment for scenarios a), c) or d) and at the date of renewal or extension period for scenario b) above.

For arrangements entered into prior to 1 January 2005, the date of inception is deemed to be 1 January 2007, in accordance with the transitional requirements of IFRIC 4.

(n) Revenue from contracts with customers

Revenue is recognised when control of goods or services transfers to the customer based on the performance obligations settle in the contracts with customers.

Sale of goods

Revenue associated with the sale of concentrates, precipitates and doré bars is recognized when control of the asset sold is transferred to the customer. Indicators of control transferring include an unconditional obligation to pay, legal title, physical possession, transfer of risk and rewards and customer acceptance. This generally occurs when the goods are delivered to the customer's smelter or refinery agreed with the buyer; at which point the buyer controls the goods.

The Group's sales contracts, in general, provide for a provisional payment based upon provisional assays and quoted metal prices. Revenues are recorded under these contracts at the time control passes to the buyer and measured at the fair value of the consideration receivable based on forward market prices set on specified quotational periods applied to the Group's best estimate of contained metal quantities.

Final settlement is based on quantities adjusted as required following the inspection of the product by the customer as well as applicable commodity prices. IFRS 15 requires that variable consideration should only be recognised to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur. As the adjustments relating to the final assay results for the quantity and quality of concentrate sold are not significant, they do not constrain the recognition of revenue.

Refining and treatment charges under the sales contracts are deducted from revenue from sales of concentrates as these are not related to a distinct good or service.

(o) Exploration expenses

Exploration activity involves the search for mineral resources, the determination of technical feasibility and the assessment of commercial viability of an identified resource.

Exploration expenses are charged to the income statement as incurred and are recorded in the following captions:

- Cost of sales: costs relating to in-mine exploration, that ensure continuous extraction quality and extend mine life, and

   -      Exploration expenses: 

o Costs incurred in geographical proximity to existing mines in order to replenish or increase reserves, and

o Costs incurred in regional exploration with the objective of locating new ore deposits in Mexico and Latin America and which are identified by project. Costs incurred are charged to the income statement until there is sufficient probability of the existence of economically recoverable minerals and a feasibility study has been performed for the specific project.

(p) Selling expenses

The Group recognises in selling expenses a levy in respect of the Extraordinary Mining Right as sales of gold and silver are recognised. The Extraordinary Mining Right consists of a 0.5% rate, applicable to the owners of mining titles. The payment must be calculated over the total sales of all mining concessions. The payment of this mining right must be remitted no later than the last business day of March of the following year and can be credited against corporate income tax.

The Group also recognises in selling expenses a discovery premium royalty equivalent to 1% of the value of the mineral extracted and sold during the year from certain mining titles granted by the Mexican Geological Survey (SGM) in the San Julian mine. The premium is settled to SGM on a quarterly basis.

(q) Taxation

Current income tax

Current income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date in the country the Group operates.

Deferred income tax

Deferred income tax is provided using the liability method on temporary differences at the balance sheet date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes.

Deferred income tax liabilities are recognised for all taxable temporary differences, except:

- where the deferred income tax liability arises from the initial recognition of goodwill or of an asset or liability in a transaction that is not a business combination and, at the time of transaction, affects neither the accounting profit nor taxable profit loss; and

- in respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, where the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.

Deferred income tax assets are recognised for all deductible temporary differences, carry forward of unused tax credits and unused tax losses, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilised, except:

- where the deferred income tax asset relating to deductible temporary differences arise from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and

- in respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred income tax assets are recognised only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilised.

The carrying amount of deferred income tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred income tax asset to be utilised.

Unrecognised deferred income tax assets are reassessed at each balance sheet date and are recognised to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be recovered.

Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realised or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the balance sheet date.

Deferred income tax relating to items recognised directly in other comprehensive income is recognised in equity and not in the income statement.

Deferred income tax assets and deferred income tax liabilities are offset, if a legally enforceable right exists to set off current tax assets against current income tax liabilities and the deferred income taxes relate to the same taxable entity and the same taxation authority.

Mining Rights

The Special Mining Right is considered an income tax under IFRS and states that the owners of mining titles and concessions are subject to pay an annual mining right of 7.5% of the profit derived from the extractive activities (See note 10 (e)). The Group recognises deferred tax assets and liabilities on temporary differences arising in the determination of the Special Mining Right (See note 10).

Sales tax

Expenses and assets are recognised net of the amount of sales tax, except:

- When the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case, the sales tax is recognised as part of the cost of acquisition of the asset or as part of the expense item, as applicable;

   -      When receivables and payables are stated with the amount of sales tax included. 

The net amount of sales tax recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the balance sheet.

(r) Derivative financial instruments and hedging

The Group uses derivatives to reduce certain market risks derived from changes in foreign exchange and commodities price which impact its financial and business transactions. Hedges are designed to protect the value of expected production against the dynamic market conditions.

Such derivative financial instruments are initially recognised at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at fair value. Derivatives are carried as assets when the fair value is positive and as liabilities when the fair value is negative. The full fair value of a derivative is classified as non-current asset or liability if the remaining maturity of the item is more than 12 months.

Any gains or losses arising from changes in fair value on derivatives during the year that do not qualify for hedge accounting are taken directly to the income statement.

Derivatives are valued using valuation approaches and methodologies (such as Black Scholes and Net Present Value) applicable to the specific type of derivative instrument. The fair value of forward currency and commodity contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles, European foreign exchange options are valued using the Black Scholes model. The Silverstream contract is valued using a Net Present Value valuation approach.

Beginning 1 January 2018, the documentation includes identification of the hedging instrument, the hedged item, the nature of the risk being hedged and how the Group will assess whether the hedging relationship meets the hedge effectiveness requirements (including the analysis of sources of hedge ineffectiveness and how the hedge ratio is determined). A hedging relationship qualifies for hedge accounting if it meets all of the following effectiveness requirements:

-- There is 'an economic relationship' between the hedged item and the hedging instrument.

-- The effect of credit risk does not 'dominate the value changes' that result from that economic relationship.

-- The hedge ratio of the hedging relationship is the same as that resulting from the quantity of the hedged item that the Group actually hedges and the quantity of the hedging instrument that the Group actually uses to hedge that quantity of hedged item.

Hedges which meet the criteria for hedge accounting are accounted for as follows:

Cash flow hedges

For derivatives that are designated and qualify as cash flow hedges, the effective portion of changes in the fair value of derivative instruments are recorded as in other comprehensive income and are transferred to the income statement when the hedged transaction affects profit or loss, such as when a forecast sale or purchase occurs. For gains or losses related to the hedging of foreign exchange risk these are included, in the line item in which the hedged costs are reflected. Where the hedged item is the cost of a non-financial asset or liability, the amounts recognised in other comprehensive income are transferred to the initial carrying amount of the non-financial asset or liability. This is not a reclassification adjustment and will not be recognised in OCI for the period. The ineffective portion of changes in the fair value of cash flow hedges is recognised directly as finance costs, in the income statement of the related period.

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover, or if its designation as a hedge is revoked, any cumulative gain or loss recognised directly in other comprehensive income from the period that the hedge was effective remains separately in other comprehensive income until the forecast transaction occurs, when it is recognised in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in other comprehensive income is immediately transferred to the income statement.

When hedging with options, the Group designates only the intrinsic value movement of the hedging option within the hedge relationship. The time value of the option contracts is therefore excluded from the hedge designation. In such cases, changes in the time value of options are initially recognised in OCI as a cost of hedging. Where the hedged item is transaction related, amounts initially recognised in OCI related to the change in the time value of options are reclassified to profit or loss or as a basis adjustment to non-financial assets or liabilities upon maturity of the hedged item, or, in the case of a hedged item that realises over time, the amounts initially recognised in OCI are amortised to profit or loss on a systematic and rational basis over the life of the hedged item.

(s) Borrowing costs

Borrowing costs directly attributable to the acquisition, construction or production of an asset that necessarily takes 12 or more months to get ready for its intended use or sale (a qualifying asset) are capitalised as part of the cost of the respective asset. Borrowing costs consist of interest and other costs that an entity incurs in connection with the borrowing of funds.

Where funds are borrowed specifically to finance a project, the amount capitalised represents the actual borrowing costs incurred. Where surplus funds are available for a short term from funds borrowed specifically to finance a project, the income generated from the temporary investment of such amounts is also capitalised and deducted from the total capitalised borrowing cost. Where the funds used to finance a project form part of general borrowings, the amount capitalised is calculated using a weighted average of rates applicable to relevant general borrowings of the Group during the period.

All other borrowing costs are recognised in the income statement in the period in which they are incurred.

(t) Fair value measurement

The Group measures financial instruments at fair value at each balance sheet date. Fair values of financial instruments measured at amortised cost are disclosed in notes 29 and 30.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

   -      In the principal market for the asset or liability, or 

- In the absence of a principal market, in the most advantageous market for the asset or liability

The principal or the most advantageous market must be accessible to the Group.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest.

A fair value measurement of a non-financial asset takes into account a market participant's ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use.

The Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximising the use of relevant observable inputs and minimising the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorised within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities

Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable

Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable

For assets and liabilities that are recognised in the financial statements on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by re-assessing categorisation (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

For the purpose of fair value disclosures, the Group has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above. Further information on fair values is described in note 29.

(u) Dividend distribution

Dividends payable to the Company's shareholders are recognised as a liability when these are approved by the Company's shareholders or Board as appropriate. Dividends payable to minority shareholders are recognised as a liability when these are approved by the Company's subsidiaries.

3. Segment reporting

For management purposes, the Group is organised into operating segments based on producing mines.

At 31 December 2018, the Group has seven reportable operating segments as follows:

   -      The Fresnillo mine, located in the state of Zacatecas, an underground silver mine; 
   -      The Saucito mine, located in the state of Zacatecas, an underground silver mine; 

- The Ciénega mine, located in the state of Durango, an underground gold mine; including the San Ramon satellite mine;

   -      The Herradura mine, located in the state of Sonora, a surface gold mine; 
   -      The Soledad-Dipolos mine, located in the state of Sonora, a surface gold mine; and 
   -      The Noche Buena mine, located in state of Sonora, a surface gold mine. 

- The San Julian mine, located on the border of Chihuahua / Durango states, an underground silver-gold mine.

The operating performance and financial results for each of these mines are reviewed by management. As the Group's chief operating decision maker does not review segment assets and liabilities, the Group has not disclosed this information.

Management monitors the results of its operating segments separately for the purpose of performance assessment and making decisions about resource allocation. Segment performance is evaluated without taking into account certain adjustments included in Revenue as reported in the consolidated income statement, and certain costs included within Cost of sales and Gross profit which are considered to be outside of the control of the operating management of the mines. The table below provides a reconciliation from segment profit to Gross profit as per the consolidated income statement. Other income and expenses included in the consolidated income statement are not allocated to operating segments. Transactions between reportable segments are accounted for on an arm's length basis similar to transactions with third parties.

In 2018 and 2017, substantially all revenue was derived from customers based in Mexico.

Operating segments

The following tables present revenue and profit information regarding the Group's operating segments for the year ended 31 December 2018 and 2017, respectively. Revenues for the year ended 31 December 2018 include those derived from contracts with costumers and other revenues, as showed in note 4.

1. The special mining right "SMR" allows the deduction of payments of mining concessions rights up to the amount of SMR payable within the same legal entity. During the fiscal year ended 31 December 2018, the Group credited US$17.3 million (2017: US$15.7 million) of mining concession rights against the SMR. Total mining concessions rights paid during the year were US$22.2 million (2017: US$16.3 million) and have been recognised in the income statement within cost of sales and exploration expenses. Mining concessions rights paid in excess of the SMR cannot be credited to SMR in future fiscal periods, and therefore no deferred tax asset has been recognised in relation to the excess. Without regards to credits permitted under the SMR regime, the current special mining right charge would have been US$28.1 million (2017: US$35.1 million).

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 tax assets and liabilities relate to the same fiscal authority.

On the basis of management's internal forecast, a deferred tax asset has been recognised in respect of tax losses amounting to US$223.5 million (2017: US$227.4 million). If not utilised, US$37.6 million (2017: US$13.7 million) will expire within five years and US$185.9 million (2017: US$213.6 million) will expire between six and ten years.

The Group has further tax losses and other similar attributes carried forward of US$42.2 million (2017: US$37.4 million) on which no deferred tax is recognised due to insufficient certainty regarding the availability of appropriate future taxable profits.

(d) Unrecognised deferred tax on investments in subsidiaries

The Group has not recognised all of the deferred tax liability in respect of distributable reserves of its subsidiaries because it controls them and only part of the temporary differences are expected to reverse in the foreseeable future. The temporary differences for which a deferred tax liability has not been recognised aggregate to US$1,430 million (2017: US$1,723 million).

(e) Corporate Income Tax ('Impuesto Sobre la Renta' or 'ISR') and Special Mining Right ("SMR")

The Group's principal operating subsidiaries are Mexican residents for taxation purposes. The rate of current corporate income tax is 30%.

During 2016 the Mexican Internal Revenue Law granted to taxpayers a credit in respect of an excise tax (Special Tax on Production and Services, or IEPS for its acronym in Spanish) paid when purchasing diesel used for general machinery and certain mining vehicles. The credit can be applied against either the Group's own corporate income tax or the income tax withheld from third parties. The credit is calculated on an entity-by-entity basis and expires one year after the purchase of the diesel. In the year ended 31 December 2018, the Group applied a credit of US$14.9 million in respect of the year (2017: US$23.2 million), which was offset by an adjustment in respect of prior years of US$7.8 million (2017: nil). Additionally, as at 31 December 2017 the Group recognised a deferred tax asset US$2.9 million in respect of the IEPS incurred in 2017 and expected to be applied during 2018. As the IEPS deduction is itself taxable, the deferred tax asset is recognised at 70% of the IEPS carried forward. The net amount applied by the Group is presented in the reconciliation of the effective tax rate in note 10(b).

The SMR states that the owners of mining titles and concessions are subject to pay an annual mining right of 7.5% of the profit derived from the extractive activities and is considered as income tax under IFRS. The SMR allows as a credit the payment of mining concessions rights up to the amount of SMR payable. The 7.5% tax applies to a base of income before interest, annual inflation adjustment, taxes paid on the regular activity, depreciation and amortization, as defined by the new ISR. This SMR can be credited against the corporate income tax of the same fiscal year and its payment must be remitted no later than the last business day of March of the following year.

11. Earnings per share

Earnings per share ('EPS') is calculated by dividing profit for the year attributable to equity shareholders of the Company by the weighted average number of Ordinary Shares in issue during the period.

The Company has no dilutive potential Ordinary Shares.

As of 31 December 2018 and 2017, earnings per share have been calculated as follows:

1 Manly corresponds to Juanicipio development project (2017: Juanicipio development project and Minera Bermejal, S.A. de C.V.).

During the year ended 31 December 2018, the Group capitalised US$11.1 million of borrowing costs within construction in progress (2017: US$11.4). Borrowing costs were capitalised at the rate of 5.78% (2017: 5.78%).

Sensitivity analysis

As at 31 December 2018 and 2017, the carrying amount of mining assets was fully supported by the higher of value in use and fair value less cost of disposal (FVLCD) computation of their recoverable amount. Value in use and FVLCD was determined based on the net present value of the future estimated cash flows expected to be generated from the continued use of the CGUs. For both valuation approaches management used long term price assumptions of US$1,310/ounce and US$19.25/ounce (2017: US$1,300/ounce and US$19/ounce) for gold and silver, respectively. Management considers that the models supporting the carrying amounts are most sensitive to commodity price assumptions and have therefore performed a sensitivity analysis for those CGUs, where a reasonable possible change in prices could lead to impairment. Management has considered a low sensitivity by decreasing gold and silver prices by 5% (2017: gold and silver 5%) and a high sensitivity by decreasing gold and silver prices by 10% and 15% respectively (2017: gold and silver 10%). As at 31 December 2018 the analysis resulted in an impairment on Herradura of US$302.7 million under high sensitivity; US$72.3 million under low sensitivity and San Julian US$159.3 million under high sensitivity; US$45.4 million under low sensitivity (2017: nil for Herradura and San Julian).

13. Silverstream contract

On 31 December 2007, the Group entered into an agreement with Peñoles through which it is entitled to receive the proceeds received by the Peñoles Group in respect of the refined silver sold from the Sabinas Mine ('Sabinas'), a base metals mine owned and operated by the Peñoles Group, for an upfront payment of US$350 million. In addition, a per ounce cash payment of $2.00 in years one to five and $5.00 thereafter (subject to an inflationary adjustment that commenced from 31 December 2013) is payable to Peñoles. The cash payment per ounce for the year ended 31 December 2018 was $5.26 per ounce (2017: $5.20 per ounce). Under the contract, the Group has the option to receive a net cash settlement from Peñoles attributable to the silver produced and sold from Sabinas, to take delivery of an equivalent amount of refined silver or to receive settlement in the form of both cash and silver. If, by 31 December 2032, the amount of silver produced by Sabinas is less than 60 million ounces, a further payment is due from Peñoles of US$1 per ounce of shortfall.

The Silverstream contract represents a derivative financial instrument which has been recorded at FVPL and classified within non-current and current assets as appropriate. The term of the derivative is based on Sabinas life of mine which is currently 35 years. Changes in the contract's fair value, other than those represented by the realisation of the asset through the receipt of either cash or refined silver, are charged or credited to the income statement. In the year ended 31 December 2018 total proceeds received in cash were US$36.3 million (2017: US$43.3 million) of which, US$4.9 million was in respect of proceeds receivable as at 31 December 2017 (2016: US$5.9 million). Cash received in respect of the year of US$31.3 million (2017: US$37.3 million) corresponds to 3.4 million ounces of payable silver (2017: 3.6 million ounces). As at 31 December 2018, a further US$3.4 million (2017: US$4.9 million) of cash receivable corresponding to 335,914 ounces of silver is due (2017: 422,375 ounces)

The US$15.0 million unrealised gain recorded in the income statement (31 December 2017: US$113.6 million gain) resulted mainly from the unwinding of the discount and the updating of the Sabinas long term mine plan, which were partially compensated by the increase in the LIBOR reference rate and the decrease in the forward silver price.

(1 Finished goods include metals contained in concentrates and doré bars, and concentrates on hand or in transit to a smelter or refinery.)

2 Work in progress includes metals contained in ores on leaching pads (note 2(c)).

(3 Ore stockpile includes ore mineral obtained during the development phase at San Julián.)

(4 The non-current inventories are expected to be processed more than 12 months from the reporting date.)

Concentrates are a product containing sulphides with variable content of precious and base metals and are sold to smelters and/or refineries. Doré is an alloy containing a variable mixture of gold and silver that is delivered in bar form to refineries. This content once processed by the smelter and refinery is sold to customers in the form of refined products.

The amount of inventories recognised as an expense in the year was US$1,323.1 million (2017: US$1,170.1 million) before changes to the net realisable value of inventory. During the year there was no adjustment to net realisable value allowance against work-in-progress inventory (2017: US$2.2 million decrease). The adjustment to the allowance for obsolete and slow-moving inventory recognised as an expense was US$0.8 million (2017: US$1.04 million).

(1 As of 31 December 2017 trade receivables from related parties includes the fair value of embedded derivatives arising due to provisional pricing in sales contracts of US$6.5 million.)

Trade receivables are shown net of any corresponding advances, are non-interest bearing and generally have payment terms of 46 to 60 days.

The total receivables denominated in US$ were US$223.1 million (2017: US$242.3million), and in Mexican pesos US$187.2 million (2017: US$100.3 million).

As of 31 December for each year presented, with the exception of 'other receivables' in the table above, all trade and other receivables were neither past due nor impaired. The amount past due and considered as impaired as of 31 December 2018 is US$0.9 million (2017: US$0.4 million). In determining the recoverability of receivables, the Group performs a risk analysis considering the type and age of the outstanding receivable and the credit worthiness of the counterparty, see note 30(b).

16. Cash and cash equivalents

The Group considers cash and cash equivalents when planning its operations and in order to achieve its treasury objectives.

Reserves

Share premium

This reserve records the consideration premium for shares issued at a value that exceeds their nominal value.

Capital reserve

The capital reserve arose as a consequence of the Pre-IPO Reorganisation as a result of using the pooling of interest method.

Hedging reserve

This reserve records the portion of the gain or loss on a hedging instrument in a cash flow hedge that is determined to be an effective hedge, net of tax. When the hedged transaction occurs, the gain or the loss is transferred out of equity to the income statement or the value of other assets.

Cost of hedging reserve

The changes in the time value of option contracts are accumulated in the costs of hedging reserve. These deferred costs of hedging are either reclassified to profit or loss or recognised as a basis adjustment to non-financial assets or liabilities upon maturity of the hedged item, or, in the case of a hedge item that realises over time, amortised on a systematic and rational basis over the life of the hedged item.

Available-for-sale financial assets reserve

As at 31 December 2017 this reserve recorded fair value changes on available-for-sale investments, net of tax. On disposal or on impairment, the cumulative changes in fair value were recycled to the income statement. These assets were reclassified upon adoption of IFRS-9, for further detail see note 2 (b).

Fair value reserve of financial assets at FVOCI

The Group has elected to recognise changes in the fair value of certain investments in equity securities in OCI, as explained in note 2(b). These changes are accumulated within the FVOCI reserve within equity. The Group transfers amounts from this reserve to retained earnings when the relevant equity securities are derecognised.

Foreign currency translation reserve

The foreign currency translation reserve is used to record exchange differences arising from the translation of the financial information of entities with a functional currency different to that of the presentational currency of the Group.

Retained earnings/accumulated losses

This reserve records the accumulated results of the Group, less any distributions and dividends paid.

18. Dividends declared and paid

19. Interest-bearing loans

Senior Notes

On 13 November 2013, the Group completed its offering of US$800 million aggregate principal amount of 5.500% Senior Notes due 2023 (the "Notes").

Movements in the year in the debt recognised in the balance sheet are as follows:

 
                                                                 As at 31 December

------------------------------------------------  ---------------  --------------- 
 

(1 Accrued interest is payable semi-annually on 13 May and 13 November.)

The Group has the following restrictions derived from the issuance of the Notes:

Change of control:

Should the rating of the senior notes be downgraded as a result of a change of control (defined as the sale or transfer of 35% or more of the common shares; the transfer of all or substantially all the assets of the Group; starting a dissolution or liquidation process; or the loss of the majority in the board of directors) the Group is obligated to repurchase the notes at an equivalent price of 101% of their nominal value plus the interest earnt at the repurchase date, if requested to do so by any creditor.

Pledge on assets:

The Group shall not pledge or allow a pledge on any property that may have a material impact on business performance (key assets). Nevertheless, the Group may pledge the aforementioned properties provided that the repayment of the Notes keeps the same level of priority as the pledge on those assets.

20. Provision for mine closure cost

The provision represents the discounted values of the estimated cost to decommission and rehabilitate the mines at the estimated date of depletion of mine deposits. Uncertainties in estimating these costs include potential changes in regulatory requirements, decommissioning, dismantling, reclamation alternatives, timing, and the discount, foreign exchange and inflation rates applied.

The Group has performed separate calculations of the provision by currency, discounting at corresponding rates. As at 31 December 2018, the discount rates used in the calculation of the parts of the provision that relate to Mexican pesos range from 7.12% to 8.55% (2017: range of 6.27% to 7.97%). The range for the current year parts that relate to US dollars range from 2.05% to 2.70% (2017: range of 1.37% to 2.22%).

Mexican regulations regarding the decommissioning and rehabilitation of mines are limited and less developed in comparison to regulations in many other jurisdictions. It is the Group's intention to rehabilitate the mines beyond the requirements of Mexican law, and estimated costs reflect this level of expense. The Group intends to fully rehabilitate the affected areas at the end of the life of the mines.

The provision is expected to become payable at the end of the production life of each mine, based on the reserves and resources, which ranges from 3 to 25 years from 31 December 2018 (3 to 27 years from 31 December 2017). As at 31 December 2018 the weighted average term of the provision is 12 years (2017:13 years)

21. Pensions and other post-employment benefit plans

The Group has a defined contribution plan and a defined benefit plan.

The defined contribution plan was established as from 1 July 2007 and consists of periodic contributions made by each non-unionised worker and contributions made by the Group to the fund matching workers' contributions, capped at 8% of the employee's annual salary.

The defined benefit plan provides pension benefits based on each worker's earnings and years of services provided by personnel hired through 30 June 2007 as well as statutory seniority premiums for both unionised and non-unionised workers.

The overall investment policy and strategy for the Group's defined benefit plan is guided by the objective of achieving an investment return which, together with contributions, ensures that there will be sufficient assets to pay pension benefits and statutory seniority premiums for non-unionised workers as they fall due while also mitigating the various risks of the plan. However, the portion of the plan related to statutory seniority premiums for unionised workers is not funded. The investment strategies for the plan are generally managed under local laws and regulations. The actual asset allocation is determined by current and expected economic and market conditions and in consideration of specific asset class risk in the risk profile. Within this framework, the Group ensures that the trustees consider how the asset investment strategy correlates with the maturity profile of the plan liabilities and the respective potential impact on the funded status of the plan, including potential short-term liquidity requirements.

Death and disability benefits are covered through insurance policies.

The following tables provide information relating to changes in the defined benefit obligation and the fair value of plan assets:

Of the total defined benefit obligation, US$7.4 million (2017: US$7.5 million) relates to statutory seniority premiums for unionised workers which are not funded. The expected contributions to the plan for the next annual reporting period are nil.

The principal assumptions used in determining pension and other post-employment benefit obligations for the Group's plans are shown below:

 
                                     As at 31 December

The life expectancy of current and future pensioners, men and women aged 65 and older will live on average for a further 23.1 and 26.6 years respectively (2017: 23.1 years for men and 26.3 for women). The weighted average duration of the defined benefit obligation is 10.8 years (2017: 11 years).

The fair values of the plan assets were as follows:

The pension plan has not invested in any of the Group's own financial instruments nor in properties or assets used by the Group.

A quantitative sensitivity analysis for significant assumptions as at 31 December 2018 is as shown below:

------------------------------  -----------  ----------  ----------  ----------  --------------- 
 

The sensitivity analysis above has been determined based on a method that extrapolates the impact on net defined benefit obligation as a result of reasonable changes in key assumptions occurring at the end of the reporting period. The pension plan is not sensitive to future changes in salaries other than in respect of inflation.

22. Trade and other payables

 
                                                      As at 31 December

---------------------------------------------  -----------  ----------- 
 

Trade payables are mainly for the acquisition of materials, supplies and contractor services. These payables do not accrue interest and no guarantees have been granted. The fair value of trade and other payables approximate their book values.

The Group's exposure to currency and liquidity risk related to trade and other payables is disclosed in note 30.

(b) Operating leases as lessee

The Group has financial commitments in respect of non-cancellable operating leases for land, offices and equipment. These leases have renewal terms at the option of the lessee with future lease payments based on market prices at the time of renewal. There are no restrictions placed upon the Group by entering into these leases.

The Group has put in place several arrangements to finance mine equipment through loans and the sale of mine equipment to contractors. In both cases, contractors are obligated to use these assets in rendering services to the Group as part of the mining work contract, during the term of financing or credit, which ranges from two to six years. The Group considers that the related mining work contracts contain embedded operating leases.

The future minimum rental commitments under these leases are as follows(1) :

(1 During the Group's IFRS 16 implementation activities, a limited number of highly certain extensions to operating lease commitments were identified. The 2017 commitments have been restated to reflect those judgements in a consistent manner.)

25. Contingencies

As of 31 December 2018, the Group has the following contingencies:

- The Group is subject to various laws and regulations which, if not observed, could give rise to penalties.

- Tax periods remain open to review by the Mexican tax authorities (SAT, by its Spanish acronym) in respect of income taxes for five years following the date of the filing of corporate income tax returns, during which time the authorities have the right to raise additional tax assessments including penalties and interest. Under certain circumstances, the reviews may cover longer periods. As such, there is a risk that transactions, and in particular related party transactions, that have not been challenged in the past by the authorities, may be challenged by them in the future.

- Other than discussed below, tax inspections that had been initiated by the SAT in previous years, were either closed or resolved through a Conclusive Agreement in 2018 or in early 2019. According to article 69-H of the Mexican Tax Code, settlements reached and executed by taxpayers and the authority may not be challenged in any way. Such settlements shall only be effective between the parties; and they shall not constitute a precedent in any case.

- With respect to Minera Penmont's 2012 and 2013 tax inspections, on July 11th, 2018 the Company filed before tax authorities a substance administrative appeal against the tax assessment, and on September 3th 2018, it filed additional documentation before tax authorities and is waiting for its response.

- On 22 October 2018 we were notified of the SAT's findings in respect of Minera Penmont's 2015 & 2016 tax inspections. The Company considers it completed the provision of all documentation required to demonstrate that the tax deductions which are being challenged, are appropriate and is waiting for the SAT's response.

- On 1 February 2019 we were notified that the SAT will conduct an inspection of Minera Saucito's 2013 tax certificate.

- It is not practical to determine the amount of any potential claims or the likelihood of any unfavourable outcome arising from these or any future inspections that may be initiated. However, management believes that its interpretation of the relevant legislation is appropriate and that the Group has complied with all regulations and paid or accrued all taxes and withholdings that are applicable.

- On 8 May 2008, the Company and Peñoles entered into the Separation Agreement (the 'Separation Agreement'). This agreement relates to the separation of the Group and the Peñoles Group and governs certain aspects of the relationship between the Fresnillo Group and the Peñoles Group following the initial public offering in May 2008 ('Admission'). The Separation Agreement provides for cross-indemnities between the Company and Peñoles so that, in the case of Peñoles, it is held harmless against losses, claims and liabilities (including tax liabilities) properly attributable to the precious metals business of the Group and, in the case of the Company, it is held harmless by Peñoles against losses, claims and liabilities which are not properly attributable to the precious metals business. Save for any liability arising in connection with tax, the aggregate liability of either party under the indemnities shall not exceed US$250 million in aggregate.

- Peñoles has agreed to indemnify the Fresnillo Group in relation to (i) any tax charge, subject to certain exceptions, the Company may incur as a result of the Pre-IPO Reorganisation (including as a result of a transaction following Admission of a member of the Fresnillo Group, provided that Peñoles has confirmed that the proposed transaction will not give rise to a tax charge, or as a result of a transaction of a member of the Peñoles Group on or after Admission), the Global Offer or Admission and (ii) certain tax aspects of certain other pre-Admission transactions. Peñoles' liability under these indemnities and in respect of general tax liabilities arising pre Admission which are not properly attributable to the precious metals business of the Fresnillo Group shall not exceed US$500 million. If a member of the Fresnillo Group forming part of Peñoles' tax consolidation pays an intra-group dividend in excess of its net income tax account ('Cuenta de Utilidad Fiscal Neta' o 'CUFIN') account after Admission and is relieved of tax as a result of the consolidation, it is required to pay Peñoles an amount in respect of that tax.

- On 30 November 2012, the Mexican government enacted a new federal labour law. During 2014 management implemented certain actions as a part of an ongoing process in order to manage the exposure resulting from the issuance of the new labour law including any potential impacts on the operations and financial position of the Group, however management does not expect any potential contingency or significant effect on the Group's financial statements as at 31 December 2018 and going forward.

   -      In regard to the ejido El Bajio matter previously reported by the Company: 

- In 2009 five members of the El Bajio agrarian community in the state of Sonora, who claimed rights over certain surface land in the proximity of the operations of Minera Penmont ("Penmont"), submitted a legal claim before the Unitarian Agrarian Court (Tribunal Unitario Agrario) of Hermosillo, Sonora, to have Penmont vacate an area of this surface land. The land in dispute encompassed a portion of surface area where part of the operations of the Soledad-Dipolos mine are located. The litigation resulted in a definitive court order, pursuant to which Penmont was ordered to vacate 1,824 hectares of land. The disputed land was returned in July 2013, resulting in the suspension of operations at Soledad-Dipolos.

- The Agrarian Court noted in that same year that certain remediation activities were necessary to comply with the relevant regulatory requirements and requested the guidance of the Federal Environmental Agency (SEMARNAT) in this respect. The Agrarian Court further issued a procedural order in execution of its ruling determining, amongst other aspects, that Penmont must remediate the lands to the state they were in before Penmont's occupation.

- In the opinion of the Company, this procedural order was excessive since this level of remediation was not part of the original agrarian ruling and also because the procedural order appeared not to consider the fact that Penmont conducted its activities pursuant to valid mining concessions and environmental impact permits. In December 2016, the Agrarian Court issued a subsequent procedural order in which the Court recognised that Penmont complied with the agrarian ruling by having returned the land in dispute and, furthermore, that remediation activities are to be conducted in accordance with Federal environmental guidelines and regulations, as supervised by the competent Federal authorities. Remediation activities in this respect are pending as the agrarian members have not yet permitted Penmont physical access to the lands. Penmont has already presented a conceptual mine closure and remediation plan before the Agrarian Court in respect of the approximately 300 hectares where Penmont conducted mining activities. The agrarian community Ejido El Bajio appealed this procedural order from the Agrarian Court and a Federal District Court denied this appeal. The agrarian community has presented in the month of August 2017 a further and last recourse against this ruling by the Federal District Court and the final result is pending.

- In addition, and as also previously reported by the Company, claimants in the El Bajio matter presented other claims against occupation agreements they entered into with Penmont, covering land parcels separate from the land described above. Penmont has no significant mining operations or specific geological interest in the affected parcels and these lands are therefore not considered strategic for Penmont. As previously reported, the Agrarian Court issued rulings declaring such occupation agreements over those land parcels to be null and void and that Penmont must remediate such lands to the state that they were in before Penmont's occupation as well as returning any minerals extracted from this area. Given that Penmont has not conducted significant mining operations nor has specific geological interest in these land parcels, any contingency relating to such land parcels is not considered material by the Company. The case relating to the claims over these land parcels remains subject to finalisation.

- Various claims and counterclaims have been made between the relevant parties in the El Bajio matter. There remains significant uncertainty as to the finalisation and ultimate outcome of these legal proceedings.

- In 2011, flooding occurred in the Saucito mine, following which the Group filed an insurance claim in respect of the damage caused (and in respect of business interruption). In early 2018, the insurance provider notified the Group that the claim had been accepted; however, there is disagreement about the appropriate amount to be paid. In October the Group received US$13.6 million in respect of the insurance claim, however this does not constitute a final settlement and management continues to pursue a higher insurance reimbursement. Due to the fact that negotiations are on-going and there is uncertainty regarding the timing of reaching an agreement with the insurer, the amount expected to be recovered is currently not practicable to determine.

- On 11 February 2019, the Supreme Court of Mexico issued a ruling regarding a specific constitutional issue presented by the former administration of the Federal Government, who challenged the ability of the State of Zacatecas to impose environmental taxes on aspects such as (i) extraction of rocks; (ii) emissions into the air; (iii) discharges of industrial residues, and (iv) disposal of industrial waste.

The ruling of the Supreme Court establishes that, from a constitutional point of view, there is no express limitation granting the Mexican State at a Federal level the sole power to impose such taxes; therefore, the State of Zacatecas has a joint right to create these taxes. Notwithstanding the foregoing, the Court did not exhaust the analysis of the legality of each particular tax created by the State of Zacatecas.

The Company had previously challenged the legality of such taxes and in 2017 obtained an injunction from a Federal court. The State of Zacatecas has appealed this ruling and the final result is pending.

1 Balance as at 31 December 2017 corresponds to the embedded derivative included in trade receivable for sales subject to provisional pricing; from 1 January 2018 onwards as a result of the adoption of IFRS 9 as explained in note 2 (b) the balance corresponds the whole trade receivable for sales subject to provisional pricing.

The fair value of the financial assets and liabilities is included at the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale.

The following valuation techniques were used to estimate the fair values:

Option and forward foreign exchange contracts

The Group enters into derivative financial instruments with various counterparties, principally financial institutions with investment grade credit ratings. The foreign currency forward (Level 2) contracts are measured based on observable spot exchange rates, the yield curves of the respective currencies as well as the currency basis spreads between the respective currencies. The foreign currency option contracts are valued using the Black Scholes model, the significant inputs to which include observable spot exchange rates, interest rates and the volatility of the currency.

Option commodity contracts

The Group enters into derivative financial instruments with various counterparties, principally financial institutions with investment grade credit ratings. The option commodity (Level 2) contracts are measured based on observable spot commodity prices, the yield curves of the respective commodity as well as the commodity basis spreads between the respective commodities. The option contracts are valued using the Black Scholes model, the significant inputs to which include observable spot commodities price, interest rates and the volatility of the commodity.

Silverstream contract

The fair value of the Silverstream contract is determined using a valuation model including unobservable inputs (Level 3). This derivative has a term of over 20 years and the valuation model utilises a number of inputs that are not based on observable market data due to the nature of these inputs and/or the duration of the contract. Inputs that have a significant effect on the recorded fair value are the volume of silver that will be produced and sold from the Sabinas mine over the contract life, the future price of silver, future foreign exchange rates between the Mexican peso and US dollar, future inflation and the discount rate used to discount future cash flows.

The estimate of the volume of silver that will be produced and sold from the Sabinas mine requires estimates of the recoverable silver reserves and resources, the related production profile based on the Sabinas mine plan and the expected recovery of silver from ore mined. The estimation of these inputs is subject to a range of operating assumptions and may change over time. Estimates of reserves and resources are updated annually by Peñoles, the operator and sole interest holder in the Sabinas mine and provided to the Company. The production profile and estimated payable silver that will be recovered from ore mined is based on the latest plan and estimates, also provided to the Company by Peñoles. The inputs assume no interruption in production over the life of the Silverstream contract and production levels which are consistent with those achieved in recent years

Management regularly assesses a range of reasonably possible alternatives for those significant unobservable inputs described above, and determines their impact on the total fair value. The significant unobservable inputs are not interrelated. The fair value of the Silverstream is not significantly sensitive to a reasonable change in future exchange rates, however, it is to a reasonable change in future silver price, future inflation and the discount rate used to discount future cash flows.

For further information relating to the Silverstream contract see note 13. The sensitivity of the valuation to the inputs relating to market risks, being the price of silver, foreign exchange rates, inflation and the discount rate is disclosed in note 30.

Equity investments:

The fair value of equity investments is derived from quoted market prices in active markets (Level 1).

Interest-bearing loans

The fair value of the Group's interest-bearing loan, is derived from quoted market prices in active markets (Level 1).

Trade receivables:

Sales of concentrates, precipitates and doré bars are 'provisionally priced' and revenue is initially recognised using this provisional price and the Group's best estimate of the contained metal. Revenue is subject to final price and metal content adjustments subsequent to the date of delivery (see note 2 (n)). This price exposure is considered to be an embedded derivative and therefore the entire related trade receivable is measured at fair value.

At each reporting date, the provisionally priced metal content is revalued based on the forward selling price for the quotational period stipulated in the relevant sales contract. The selling price of metals can be reliably measured as these metals are actively traded on international exchanges but the estimated metal content is a non-observable input to this valuation.

(c) Derivative financial instruments

The Group enters into certain option contracts to manage its exposure to commodity price risk as described in note 2 (r).

The Group sells gold as the primary product of the Group's open-pit mines. Upon the acquisition of the remaining 46% interest in the Penmont mines in 2014, the Group entered into commodity option contracts to protect the value of future sales related to that previous non-controlling interest over a period of five years. The Group also sells lead and zinc as a by-product in certain of its mines. Except in relation to the acquisition of the remaining in interest in the Penmont mines described above, the Group's risk management strategy is to not hedge primary metal prices and hedge by-product metals in certain market conditions. The Group monitors metal price volatility in order to determine when to enter into new hedging contracts related to by-products. New contracts were entered into in 2017 but not in 2018. These contracts are expected to reduce the volatility attributable to metals price fluctuations. Hedging the price volatility of forecast metals sales is in accordance with the risk management strategy outlined by the Board of Directors.

There is an economic relationship between the hedged items and the hedging instruments as the terms of the commodity option contracts match the terms of the expected highly probable forecast sales (i.e., notional amount and expected payment date). The Group has established a hedge ratio of 1:1 for the hedging relationships as the underlying risks of the commodity option contracts are identical to the hedged risk components. To test the hedge effectiveness, the Group uses the hypothetical derivative method and compares the changes in the fair value of the hedging instruments against the changes in fair value of the hedged items attributable to the hedged risks.

Due to the terms of the Group's hedge relationships, the change in the fair value of both the hedging instrument and hedged items equalled the amounts recognised in other comprehensive income in the following paragraphs. The amounts recycled to the income statement in respect of these contracts are recognised in revenue; ineffectiveness is recognised in finance cost.

Gold option contracts

As at 31 December 2018, the outstanding collar derivative instruments mature over the period from 31 January 2019 to 30 December 2019 and hedge cash proceeds for the sales of gold production amounting 346,152 ounces (2017: 712,584 ounces) with a floor price of US$1,100:1 ounce, a range of capped prices from US$1,375 to US$1,495:1 ounce (2017: US$1,375 to US$1,495:1 ounce) and weighted average capped price of US$1,424:1 ounce (2017: US$1,423 :1 ounce). The fair value of the put options as at 31 December 2018 was an asset of US$0.9 million (2017: US$3.7 million), and the fair value of the call options at 31 December 2018 was a liability of US$4.6 million (2017:US$21.8 million). In 2018 the changes in the fair value of the option contracts corresponding to the time value amounted to US$14.4 million and was recorded in other comprehensive income; in 2017 fair value amounted of US$41.1 million was recorded in the income statement.

Lead option contracts

As at 31 December 2018 there were no outstanding options related to lead contracts. As at 31 December 2017, lead collar derivative instruments hedge lead production amounting 21,168 tonnes with a floor price of US$2,370:1 tonne, a range of capped prices from US$2,730 to US$2,740:1 tonne and weighted average cap price of US$2,735:1 tonne. The fair value of the put options at 31 December 2017 was an asset of US$0.5 million, and the fair value of the call options at 31 December 2017 was a liability of US$0.5 million. The gain recycled to the income statement in the period was US$1.0 million (2017: nil).

Zinc option contracts

As at 31 December 2018 there were no outstanding options related to zinc contracts. As at 31 December 2017, zinc collar derivative instruments hedge lead production amounting 5,760 tonnes with a range of floor prices of US$2,500 to 2,756:1 tonne and weighted average floor price of US$2,591:1 tonne, a range of capped prices from US$3,650 to US$3,800:1 tonne and weighted average cap price of US$3,716:1 tonne. The fair value of the put options at 31 December 2017 was an asset of US$0.5 million, and the fair value of the call options at 31 December 2017 was a liability of US$1.5 million. The gain recycled to the income statement in the period was US$0.6 million (2017: nil).

30. Financial risk management

Overview

The Group's principal financial assets and liabilities, other than derivatives, comprise trade receivables, cash, equity instruments at FVOCI, interest-bearing loans and trade payables.

The Group has exposure to the following risks from its use of financial instruments:

- Market risk, including foreign currency, commodity price, interest rate, inflation rate and equity price risks

   -      Credit risk 
   -      Liquidity risk 

This note presents information about the Group's exposure to each of the above risks and the Group's objectives, policies and processes for assessing and managing risk. Further quantitative disclosures are included throughout the financial statements.

The Board of Directors has overall responsibility for the establishment and oversight of the Group's risk management framework.

The Group's risk management policies are established to identify and analyse the risks faced by the Group, to set appropriate risk limits and controls, and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Group's activities. The Group, through its training and management standards and procedures, aims to develop a disciplined and constructive control environment in which all employees understand their roles and obligations.

The Fresnillo Audit Committee has responsibility for overseeing how management monitors compliance with the Group's risk management policies and procedures and reviews the adequacy of the risk management framework in relation to the risks faced by the Group. The Audit Committee is assisted in its oversight role by Internal Audit, which undertakes both regular and ad hoc reviews of risk management controls and procedures, the results of which are reported to the Audit Committee.

(a) Market risk

Market risk is the risk that changes in market factors, such as foreign exchange rates, commodity prices or interest rates will affect the Group's income or the value of its financial instruments.

The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimising the return on risk.

In the following tables, the effect on equity excludes the changes in retained earnings as a direct result of changes in profit before tax.

Foreign currency risk

The Group has financial instruments that are denominated in Mexican peso, euro and Swedish krona which are exposed to foreign currency risk. Transactions in currencies other than the US dollar include the purchase of services, fixed assets, spare parts and the payment of dividends. As a result, the Group has financial assets and liabilities denominated in currencies other than functional currency, and holds cash and cash equivalents in Mexican Peso.

In order to manage the Group's exposure to foreign currency risk on expenditure denominated in currencies other than the US dollar, the Group has entered into certain forward and option derivative contracts with maturity dates from 2018 (see note 29 for additional detail).

The following table demonstrates the sensitivity of financial assets and financial liabilities (excluding Silverstream) to a reasonably possible change in the US dollar exchange rate compared to the Mexican peso, reflecting the impact on the Group's profit before tax and equity, with all other variables held constant. It is assumed that the same percentage change in exchange rates is applied to all applicable periods for the purposes of calculating the sensitivity with relation to derivative financial instruments.

Commodity risk

The Group has exposure to changes in metals prices (specifically silver, gold, lead and zinc) which have a significant effect on the Group's results. These prices are subject to global economic conditions and industry-related cycles.

The Group uses derivative instruments to hedge against an element of gold, zinc and lead price.

The table below reflects the aggregate sensitivity of financial assets and liabilities (excluding Silverstream) to a reasonably possible change in commodities prices, reflecting the impact on the Group's profit before tax with all other variables held constant.

The sensitivity shown in the table below relates to changes in fair value of commodity derivatives financial instruments contracts and embedded derivatives in sales.

Commodity price risk - Silverstream

Future silver price is one of the inputs to the Silverstream valuation model. The following table demonstrates the sensitivity of the Silverstream contract valuation to a reasonably possible change in future silver prices, with all other inputs to the Silverstream valuation model held constant. It is assumed that the same percentage change in silver price is applied to all applicable periods in the valuation model. There is no impact on the Group's equity, other than the equivalent change in retained earnings.

Interest rate risk

The Group is exposed to interest rate risk from the possibility that changes in interest rates will affect future cash flows or the fair values of its financial instruments, principally relating to the cash balances and the Silverstream contract held at the balance sheet date. Interest-bearing loans are at a fixed rate, therefore the possibility of a change in interest rate only impacts its fair value but not its carrying amount. Therefore, interest-bearing loans and loans from related parties are excluded from the table below.

The following table demonstrates the sensitivity of financial assets and financial liabilities (excluding Silverstream) to a reasonably possible change in interest rate applied to a full year from the balance sheet date. There is no impact on the Group's equity other than the equivalent change in retained earnings.

(b) Credit risk

Exposure to credit risk arises as a result of transactions in the Group's ordinary course of business and is applicable to all financial assets and derivative financial instruments. The financial assets are trade and other receivables, cash and cash equivalents, short-term investments, the Silverstream contract and available-for-sale financial assets.

The Group's policies are aimed at minimising losses as a result of counterparties' failure to honour their obligations. Individual exposures are monitored with customers subject to credit limits to ensure that the Group's exposure to bad debts is not significant. The Group's exposure to credit risk is influenced mainly by the individual characteristics of each counter party. The Group's financial assets are with counterparties with what the Group considers to have an appropriate credit rating. As disclosed in note 26, the counterparties to a significant proportion of these financial assets are related parties. At each balance sheet date, the Group's financial assets were neither impaired nor past due, other than 'Other receivables' as disclosed in note 16. The Group's policies are aimed at minimising losses from foreign currency hedging contracts. The Company's foreign currency hedging contracts are entered into with large financial institutions with strong credit ratings.

The Group has a high concentration of trade receivables with one counterparty Met-Mex Peñoles, the Group's primary customer throughout 2018 and 2017. A further concentration of credit risk arises from the Silverstream contract. Both Met-Mex and the counterparty to the Silverstream contract are subsidiaries in the Peñoles group which currently owns 75 per cent of the shares of the Company and is considered by management to be of appropriate credit rating.

The Group's surplus funds are managed by Servicios Administrativos Fresnillo, S.A. de C.V., which manages cash and cash equivalents, including short-term investments investing in a number of financial institutions. Accordingly, on an ongoing basis the Group deposits surplus funds with a range of financial institutions, depending on market conditions. In order to minimise exposure to credit risk, the Group only deposits surplus funds with financial institutions with a credit rating of MX-1 (Moody's) and mxA-1+ (Standard and Poor's) and above. As at 31 December 2018, the Group had concentrations of credit risk as 19 percent of surplus funds were deposited with one financial institution of which the total investment was held in short term Mexican government paper.

The maximum credit exposure at the reporting date of each category of financial asset above is the carrying value as detailed in the relevant notes. See note 16 for the maximum credit exposure to cash and cash equivalents, note 27 for related party balances with Met-Mex and note 29 for equity instruments at FVOCI. The maximum credit exposure with relation to the Silverstream contract is the value of the derivative as at 31 December 2018, being US$519.1 million (2017: US$538.9 million).

(c) Liquidity risk

Liquidity risk is the risk that the Group will not be able to meet its financial obligations as they fall due.

The Group monitors its risk of a shortage of funds using projected cash flows from operations and by monitoring the maturity of both its financial assets and liabilities.

The table below summarises the maturity profile of the Group's financial liabilities based on contractual undiscounted payments.

The above liquidity tables include expected inflows and outflows from currency option contracts which the Group expects to be exercised during 2019 as at 31 December 2018 and during 2018 as at 31 December 2017, either by the Group or counterparty.

Management considers that the Group has adequate current assets and forecast cash from operations to manage liquidity risks arising from current liabilities and non-current liabilities.

Capital management

The primary objective of the Group's capital management is to ensure that it maintains a strong credit rating and healthy capital ratios that support its business and maximise shareholder value. Management considers capital to consist of equity and certain interest-bearing loans, including loans from related parties, as disclosed in the balance sheet, excluding net unrealised gains or losses on revaluation of cash flow hedges and available-for-sale financial assets. In order to ensure an appropriate return for shareholder's capital invested in the Group management thoroughly evaluates all material projects and potential acquisitions and approves them at its Executive Committee before submission to the Board for ultimate approval, where applicable. The Group's dividend policy is based on the profitability of the business and underlying growth in earnings of the Group, as well as its capital requirements and cash flows, including cash flows from the Silverstream.

In managing its capital, the Group considers its cash and other liquid asset position, as set out below:
