SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: | NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Principles of consolidation— The consolidated financial statements include the accounts of subsidiaries of which the Company has voting control, in accordance with Accounting Standards Codification ("ASC") 810 Consolidation . Such financial statements are prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). Use of estimates— The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include the carrying value of ore reserves that are the basis for future cash flow estimates and amortization calculations; environmental reclamation, closure and retirement obligations; estimates of recoverable copper in mill and leach stockpiles; asset impairments (including estimates of future cash flows); unrecognized tax benefits; valuation allowances for deferred tax assets; and fair value of financial instruments. Management bases its estimates on the Company's historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates. Revenue recognition— Substantially all of the Company's copper and non-copper products are sold under annual or other longer-term contracts. Revenue is recognized when title passes to the customer. The passing of title is based on terms of the contract, generally upon shipment. Copper and non-copper revenues are determined based on the monthly average of prevailing commodity prices according to the terms of the contracts. The Company provides allowances for doubtful accounts based upon historical bad debt and claims experience and periodic evaluation of specific customer accounts. For certain of the Company's sales of copper and molybdenum products, customer contracts allow for pricing based on a month subsequent to shipping, in most cases within the following three months and occasionally in some cases a few additional months. In such cases, revenue is recorded at a provisional price at the time of shipment. The provisionally priced copper sales are adjusted to reflect forward LME or COMEX copper prices at the end of each month until a final adjustment is made to the price of the shipments upon settlement with customers pursuant to the terms of the contract. In the case of molybdenum sales, for which there are no published forward prices, the provisionally priced sales are adjusted to reflect the market prices at the end of each month until a final adjustment is made to the price of the shipments upon settlement with customers pursuant to the terms of the contract. These provisional pricing arrangements are accounted for separately from the contract as an embedded derivative instrument under ASC 815-30 "Derivatives and Hedging—Cash Flow Hedges." The Company sells copper in concentrate, anode, blister and refined form at industry standard commercial terms. Net sales include the invoiced value of copper, zinc, silver, molybdenum, sulfuric acid and other metals and the corresponding fair value adjustment of the related forward contract of copper and molybdenum. Shipping and handling fees and costs— Amounts billed to customers for shipping and handling are classified as sales. Amounts incurred for shipping and handling are included in cost of sales (exclusive of depreciation, amortization and depletion). Cash and cash equivalents— Cash and cash equivalents include bank deposits, certificates of deposit and short-term investment funds with original maturities of three months or less at the date of purchase. The carrying value of cash and cash equivalents approximates fair value. Short-term investments— The Company accounts for short-term investments in accordance with ASC 320-10 "Investments Debt and Equity Securities—Recognition." The Company determines the appropriate classification of all short-term investments as held-to-maturity, available-for-sale or trading at the time of purchase and re-evaluates such classifications as of each balance sheet date. Unrealized gains and losses on available-for-sale investments, net of taxes, are reported as a component of accumulated other comprehensive income (loss) in stockholders' equity, unless such loss is deemed to be other than temporary. Inventories— The Company principally produces copper and, in the production process, obtains several by-products, including molybdenum, silver, zinc, sulfuric acid and other metals. Metal inventories, consisting of work-in-process and finished goods, are carried at the lower of average cost or market. Costs incurred in the production of metal inventories exclude general and administrative costs. Once molybdenum, silver, zinc and other by-products are identified, they are transferred to their respective production facilities and the incremental cost required to complete production is assigned to their inventory value. Work-in-process inventories represent materials that are in the process of being converted into a saleable product. Conversion processes vary depending on the nature of the copper ore and the specific mining operation. For sulfide ores, processing includes milling and concentrating and results in the production of copper and molybdenum concentrates. Finished goods include saleable products (e.g., copper concentrates, copper anodes, copper cathodes, copper rod, molybdenum concentrate and other metallurgical products). Supplies inventories are carried at the lower of average cost or market. Long-term inventory—Ore stockpiles on leach pads. The leaching process is an integral part of the mining operations carried out at the Company's open-pit mines. The Company capitalizes the production cost of leachable material at its Toquepala, La Caridad and Buenavista mines recognizing it as inventory. The estimates of recoverable mineral content contained in the leaching dumps are supported by engineering studies. As the production cycle of the leaching process is significantly longer than the conventional process of concentrating, smelting and electrolytic refining, the Company includes on its balance sheet current leach inventory (included in work-in-process inventories) and long-term leach inventory. Through 2013, the cost attributed to the leach material was charged to cost of sales over a five-year period, which was considered the average estimated recovery period based on the historical recovery percentages of each mine. During the fourth quarter of 2014, the Company completed the construction of a new plant that has resulted in increased efficiency in production and use of leachable material. Accordingly, the Company changed its method of amortization to the units of production method. This change in estimate effected by a change in accounting principle results in a better matching of costs to revenues as a result of the improved production levels from the new plant and results in a better estimate of current and long-term leachable material inventory. Property— Property is recorded at acquisition cost, net of accumulated depreciation and amortization. Cost includes major expenditures for improvements and replacements, which extend useful lives or increase capacity and interest costs associated with significant capital additions. Maintenance, repairs, normal development costs at existing mines and gains or losses on assets retired or sold are reflected in earnings as incurred. Buildings and equipment are depreciated on the straight-line method over estimated lives from five to 40 years or the estimated life of the mine if shorter. Mine development— Mine development includes primarily the cost of acquiring land rights to an exploitable ore body, pre-production stripping costs at new mines that are commercially exploitable, costs associated with bringing new mineral properties into production, and removal of overburden to prepare unique and identifiable areas outside the current mining area for such future production. Mine development costs are amortized on a unit of production basis over the remaining life of the mines. There is a diversity of practices in the mining industry in the treatment of drilling and other related costs to delineate new ore reserves. The Company follows the practices outlined in the next two paragraphs in its treatment of drilling and related costs. Drilling and other associated costs incurred in the Company's efforts to delineate new resources, whether near-mine or Greenfield are expensed as incurred. These costs are classified as mineral exploration costs. Once the Company determines through feasibility studies that proven and probable reserves exist and that the drilling and other associated costs embody a probable future benefit that involves a capacity, singly or in combination with other assets, to contribute directly or indirectly to future net cash inflow, then the costs are classified as mine development costs. These mine development costs incurred prospectively to develop the property are capitalized as incurred, until the commencement of production, and are amortized using the units of production method over estimated life of the ore body. During the production stage, drilling and other related costs incurred to maintain production are included in production cost in the period in which they are incurred. Drilling and other related costs incurred in the Company's efforts to delineate a major expansion of reserves at an existing production property are expensed as incurred. Once the Company determines through feasibility studies that proven and probable incremental reserves exist and that the drilling and other associated costs embody a probable future benefit that involves a capacity, singly or in combination with other assets, to contribute directly or indirectly to future net cash inflow, then the costs are classified as mine development costs. These incremental mine development costs are capitalized as incurred, until the commencement of production and amortized using the units of production method over the estimated life of the ore body. A major expansion of reserves is one that increases total reserves at a property by approximately 10% or more. For the years ended December 31, 2016, 2015 and 2014, the Company did not capitalize any drilling and related costs. Asset retirement obligations (reclamation and remediation costs)— The fair value of a liability for asset retirement obligations is recognized in the period in which the liability is incurred. The liability is measured at fair value and is adjusted to its present value in subsequent periods as accretion expense is recorded. The corresponding asset retirement costs are capitalized as part of the carrying value of the related long-lived assets and depreciated over the asset's useful life. Intangible assets— Intangible assets include primarily the excess amount paid over the book value for investment shares which are presented as mining concessions, and mining and engineering development studies. Intangible assets are carried at acquisition costs, net of accumulated amortization and are amortized principally on a unit of production basis over the estimated remaining life of the mines. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Debt issuance costs— Debt issuance costs related to a recognized debt liability are presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with the treatment of a debt discount. Ore reserves— The Company periodically reevaluates estimates of its ore reserves, which represent the Company's estimate as to the amount of unmined copper remaining in its existing mine locations that can be produced and sold at a profit. Such estimates are based on engineering evaluations derived from samples of drill holes and other openings, combined with assumptions about copper market prices and production costs at each of the respective mines. The Company updates its estimate of ore reserves at the beginning of each year. In this calculation, the Company uses current metal prices which are defined as the average metal price over the preceding three years. The current price per pound of copper, as defined, was $2.61, $2.99 and $3.36 at the end of 2016, 2015 and 2014, respectively. The ore reserve estimates are used to determine the amortization of mine development and intangible assets. Once the Company determines through feasibility studies that proven and probable reserves exist and that the drilling and other associated costs embody a probable future benefit that involves a capacity, singly or in combination with other assets, to contribute directly or indirectly to future net cash inflow, then the costs are classified as mine development costs and the Company discloses the related ore reserves. Exploration— Tangible and intangible costs incurred in the search for mineral properties are charged against earnings when incurred. Income taxes— Provisions for income taxes are based on taxes payable or refundable for the current year and deferred taxes on temporary differences between the amount of taxable income and pretax financial income and between the tax bases of assets and liabilities and their reported amounts in the financial statements. Deferred tax assets and liabilities are included in the financial statements at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized and settled as prescribed in ASC 740 "Income taxes." As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Deferred income tax assets are reduced by any benefits that, in the opinion of management, are more likely not to be realized. The Company's operations involve dealing with uncertainties and judgments in the application of complex tax regulations in multiple jurisdictions. The final taxes paid are dependent upon many factors, including negotiations with taxing authorities in various jurisdictions and resolution of disputes arising from federal, state, and international tax audits. The Company recognizes potential liabilities and records tax liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on its estimate of whether, and the extent to which, additional taxes will be due. The Company follows the guidance of ASC 740 "Income taxes" to record these liabilities. (See Note 8 "Income taxes" of the consolidated financial statements for additional information). The Company adjusts these reserves in light of changing facts and circumstances; however, due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the Company's current estimate of the tax liabilities. If its estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities would result in tax benefits being recognized in the period when the Company determines the liabilities are no longer necessary. The Company classifies income tax-related interest and penalties as income taxes in the financial statements, as well as interest and penalties, if any, related to unrecognized tax benefits. Foreign exchange— The Company's functional currency is the U.S. dollar. As required by local law, both the Peruvian Branch and Minera Mexico maintain their books of accounts in Peruvian soles and Mexican pesos, respectively. Foreign currency assets and liabilities are remeasured into U.S. dollars at current exchange rates, except for non-monetary items such as inventory, property, intangible assets and other assets which are remeasured at historical exchange rates. Revenues and expenses are generally translated at actual exchange rates in effect during the period, except for those items related to balance sheet amounts that are remeasured at historical exchange rates. Gains and losses from foreign currency remeasurement are included in earnings of the period. Gains and (losses) resulting from foreign currency transactions are included in "Cost of sales (exclusive of depreciation, amortization and depletion)." Asset impairments— The Company evaluates long-term assets when events or changes in economic circumstances indicate that the carrying amount of such assets may not be recoverable. These evaluations are based on business plans that are prepared using a time horizon that is reflective of the Company's expectations of metal prices over its business cycle. The Company is currently using a long-term average copper price and an average molybdenum price for impairment tests, reflective of what the Company believes is the lower level of the current price environment. The results of its impairment tests using these long-term copper and molybdenum prices show no impairment in the carrying value of their assets. In recent years testing using assumptions for long-term average prices have resulted in stricter evaluation for impairment analysis than would the higher three year average prices for copper and molybdenum prices. Should this situation reverse in the future with three year average prices below the long-term price assumption, the Company would assess the need to use the three year average prices in its evaluations. The Company uses an estimate of the future undiscounted net cash flows of the related asset or asset group over the remaining life to measure whether the assets are recoverable and measures any impairment by reference to fair value. Other comprehensive income— Comprehensive income represents changes in equity during a period, except those resulting from investments by owners and distributions to owners. During the fiscal years ended December 31, 2016, 2015 and 2014, the components of "other comprehensive income (loss)" were, the unrecognized gain (loss) on employee benefit obligations and unrealized gain (loss) on available-for-sale securities (which were not material in the aforementioned years). Business segments— Company management views Southern Copper as having three reportable segments and manages it on the basis of these segments. The segments identified by the Company are: 1) the Peruvian operations, which include the two open-pit copper mines in Peru and the plants and services supporting such mines, 2) the Mexican open-pit copper mines, which include La Caridad and Buenavista mine complexes and their supporting facilities and 3) the Mexican underground mining operations, which include five underground mines that produce zinc, lead, copper, silver and gold, a coal mine and a zinc refinery. Please see Note 18 "Segments and Related Information." Senior management officers of the Company focus on operating income as measure of performance to evaluate different segments, and to make decisions to allocate resources to the reported segments. These are common measures in the mining industry. PROPOSED ACCOUNTING STANDARDS In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers" (Topic 606). The objective of the new revenue standard is to provide a single comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries and across capital markets. The core principle of the standard is that the Company should recognize revenue to represent the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. The Company should apply the following five steps to achieve the core principle: Step 1: Identify the contract(s) with a customer. Step 2: Identify the performance obligations (promises) in the contract. Step 3: Determine the transaction price. Step 4: Allocate the transaction price to the performance obligations in the contract. Step 5: Recognize revenue when (or as) the Company satisfies a performance obligation. The guidance also specifies the accounting for some costs to obtain or fulfill a contract with a customer. Additionally, the Company should disclose sufficient qualitative and quantitative information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. On July 9, 2015, the FASB approved a one year deferral of the effective date of the new revenue standard for all entities. This revenue standard is effective for the first interim period within annual reporting periods beginning after December 15, 2017, and early adoption is not permitted. The Company is evaluating the impact of the adoption of this new standard on the consolidated financial information. |

Accordingly, SCC's results are included in the consolidated results of the Grupo Mexico subsidiary for U.S. federal income tax reporting. SCC provides current and deferred income taxes, as if it were filing a separate income tax return. The components of the provision for income taxes for the three years ended December 31, 2016, are as follows: (in millions) 2016 2015 2014 U.S. federal and state: Current $ — $ — $ — Deferred ) ) ) Uncertain tax positions ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ) ) ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign (Peru and Mexico): Current Deferred ) ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total provision for income taxes $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The source of income is as follows: (in millions) 2016 2015 2014 Earnings by location: U.S. $ ) $ ) $ ) Foreign Peru ) Mexico ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Earnings before taxes on income $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The reconciliation of the statutory income tax rate to the effective tax rate for the three years ended December 31, 2016, is as follows (in percentage points): 2016 2015 2014 Expected tax at U.S. statutory rate % % % Foreign tax at other than statutory rate, net of foreign tax credit benefit(1) Percentage depletion ) ) ) Other permanent differences — Increase (decrease) in unrecognized tax benefits for uncertain tax positions Repatriated foreign earnings — ) Amounts (over) / under provided in prior years ) ) Other ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Effective income tax rate % % % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (1) Foreign tax at other than statutory rates, net of foreign tax credit benefit, also includes the effects of permanent differences in Peru and Mexico, that are determined at the local statutory rate. The Company files income tax returns in three jurisdictions, Peru, Mexico and the United States. For the three years presented above, the statutory income tax rate for Mexico was 30% and 35% for the United States. The Peruvian tax rate was 28% for 2016 and 2015 and 30% for 2014. While the largest components of income taxes are the Peruvian and Mexican taxes, the Company is a domestic U.S. entity. Therefore, the rate used in the above reconciliation is the U.S. statutory rate. For all of the years presented, both the Peruvian branch and Minera Mexico filed separate tax returns in their respective tax jurisdictions. Although the tax rules and regulations imposed in the separate tax jurisdictions may vary significantly, similar permanent items exist, such as items which are nondeductible or nontaxable. Some permanent differences relate specifically to SCC such as the allowance in the United States for percentage depletion. Deferred taxes include the U.S., Peruvian and Mexican tax effects of the following types of temporary differences and carryforwards: At December 31, (in millions) 2016 2015 Assets: Inventories $ $ Capitalized exploration expenses U.S. foreign tax credit carryforward, net of FIN 48 liability U.S. tax effect of Peruvian deferred tax liability Property, plant and equipment — Reserves Mexican tax on consolidated dividends Prepaids Other ​ ​ ​ ​ ​ ​ ​ ​ Total deferred tax assets ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: Property, plant and equipment — ) Deferred charges ) ) Unremitted foreign earnings ) — Other ) ) ​ ​ ​ ​ ​ ​ ​ ​ Total deferred tax liabilities ) ) ​ ​ ​ ​ ​ ​ ​ ​ Total net deferred tax assets / (liabilities) $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Tax Matters— As of December 31, 2016, the Company considers its ownership of the stock of Minera Mexico to be essentially permanent in duration. The excess of the amount for financial reporting over the tax basis of the investment in this stock is estimated to be at least $6.7 billion. As of December 31, 2016, $509.7 million of the Company's cash, cash equivalents, restricted cash and short-term investments of $600.9 million was held by foreign subsidiaries. The cash, cash equivalents and short-term investments maintained in the Company's foreign operations are generally used to cover local operating and investment expenses. At December 31, 2016, Minera Mexico determined that it has $470.5 million in earnings available for dividends to the United States. These earnings have not been remitted, but U.S. federal income tax, net of foreign tax credit utilization was recognized in 2016 resulting in an increase tax of $45.7 million. At December 31, 2015, Minera Mexico had determined that it had no remittable earnings available for dividends to the United States due to its internal financial obligations and expansion plans and had met the indefinite reversal criteria of ASC 740-30-25-17 that it intended to reinvest its earnings indefinitely. Any distribution of earning from the Company's Mexican subsidiaries to the United States is subject to a U.S. federal income tax that equates to approximately 10% of the amount of the distribution, after considering foreign tax credit utilization. Distributions of earnings from the Company's Peruvian branch to the United States are not subject to repatriation taxes. The Company's Peruvian operations are not foreign subsidiaries. Rather they are mainly comprised of operations that are treated as a branch of the Company's U.S. operations from a tax perspective. At December 31, 2016, there were $577.1 million of foreign tax credits available for carryback or carryforward. These credits have a one year carryback and a ten year carryforward period and can only be used to reduce U.S. income tax on foreign earnings. There were no other unused U.S. tax credits at December 31, 2016. These credits expire as follows: Year Amount 2019 2020 2021 2022 2023 2024 2025 2026 ​ ​ ​ ​ ​ Total $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ These foreign tax credits are presented above on a gross basis and have not been reduced here for any unrecognized tax benefits. These foreign tax credits have been adjusted to include the 2016 Net Operating Loss carryback in the U.S. jurisdiction, increasing foreign tax credits by approximately $13.6 million. In accordance with ASU 2013-11 the Company has recorded $295.2 million of an unrecognized tax benefit as an offset to the Company's deferred tax asset for foreign tax credits. The remaining foreign tax credits of $281.9 million will be used to offset future liabilities but can expire if not utilized by 2023 ($11.3 million), 2024 ($36.3 million), 2025 ($141.5 million) and 2026 ($92.8 million). At this time, the Company considers it more likely than not that it will have sufficient taxable income in the future that will allow it to utilize these credits. However, based on a variety of factors (such as metal prices and tax rates), it is possible that some or all of the credits could ultimately expire unused and require a valuation allowance that could materially increase tax expense. Peruvian Tax Matters— Royalty mining charge: The royalty charge is based on operating income margins with graduated rates ranging from 1% to 12% of operating profits, with a minimum royalty charge assessed at 1% of net sales. If the operating income margin is 10% or less, the royalty charge is 1% and for each 5% increment in the operating income margin, the royalty charge rate increases by 0.75%, up to a maximum of 12%. The minimum royalty charge assessed at 1% of net sales is recorded as cost of sales and those amounts assessed against operating income are included in the income tax provision. The Company has accrued $16.8 million, $22.9 million and $32.4 million of royalty charges in 2016, 2015 and 2014, respectively, of which $2.7 million and $7.5 million were included in income taxes in 2015 and 2014, respectively; no amounts were included in income tax in 2016. Peruvian special mining tax: This tax is based on operating income and its rate ranges from 2% to 8.4%. It begins at 2% for operating income margin up to 10% and increases by 0.4% of operating income for each additional 5% of operating income until 85% of operating income is reached. The Company recognized $10.8 million, $18.1 million and $35.3 million in 2016, 2015 and 2014, respectively, with respect to this tax. These amounts are included as "income taxes" in the consolidated statement of earnings. In 2014, the income tax rate was 30% and the dividend tax rate was 4.1%. In 2014, the Peruvian congress enacted tax law changes to both the income tax and dividend tax rates that become effective on January 1, 2015 until December 31, 2016. The rates were as follows: Year Income Dividend 2015 - 2016 % % In December 2016, the Peruvian Government enacted income tax law changes to both the income tax and dividend tax rate that become effective on January 1, 2017. The new rates are as follows: Year Income Dividend 2017 and later % % The recalculation of the deferred tax liability for the Peruvian jurisdiction using the new tax rates did not have a material effect on the deferred tax liability or the financial statements of the Company. Mexican Tax Matters— In 2013, the Mexican Congress enacted tax law changes that became effective on January 1, 2014. Among other effects, the amounts that the subsidiary companies of Minera Mexico recorded during 2016 were: • Mining royalty at the rate of 7.5% on taxable earnings before taxes: $48.9 million. • Additional royalty of 0.5% over gross income from sales of gold, silver and platinum: $0.8 million. • The cancellation of the consolidation regime, paid in March 2016: $0.01 million. • Income tax payable stemming from changes to tax consolidation: $0.3 million. A new tax bill enacted in 2016, presented by the President to the Congress, was approved by both Chambers of Congress on October 29, 2015 and released in the Official Gazette of the Federation on November 18, 2015. Most of the respective legislative amendments became effective as of January 1, 2016 and include amendments to the Federal Income Tax Law, to the Excise Law and to the Federal Tax Code. The most relevant changes applicable to Minera Mexico and subsidiaries are: i) new tax reporting and tax compliance obligations for corporations and financial institutions, mainly derived from the implementations of certain OECD´s (Organization of Economic Cooperation and Development) Base Erosion and Profit Shifting (BEPS) and automatic exchange of information initiatives; ii) relief measures and clarifications to rules dealing with the tax regime applicable to private equity and venture capital trusts and groups of companies that previously filed consolidated income tax returns. Accounting for Uncertainty in Income Taxes— The total amount of unrecognized tax benefits in 2016, 2015 and 2014, was as follows (in millions): 2016 2015 2014 Unrecognized tax benefits, opening balance $ $ $ Gross increases—tax positions in prior period Gross increases—current-period tax positions Decreases related to settlements with taxing authorities ) — — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Unrecognized tax benefits, ending balance $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $304.0 million and $400 million at December 31, 2016 and 2015, respectively. These amounts relate entirely to U.S. income tax matters. The Company has no unrecognized Peruvian or Mexican tax benefits. The settlement with taxing authorities of $123.2 million resulted in a cash refund of $1.5 million and a reduction in foreign tax credits for the remainder. The Company is currently under examination by the Internal Revenue Service for the years 2011-2013 as part of the audit of the AMC consolidated tax group. Unrecognized tax benefits included a liability of $224.0 million from 2012; however, the parent company expects to benefit from offsetting tax benefits of the same amount and therefore would not ultimately require a cash payment from the Company with respect to the unrecognized tax benefit. Accordingly, the liability was derecognized in the consolidated financial statements and thus is not reflected in the aforementioned table. As of December 31, 2016 and December 31, 2015 the Company's liability for uncertain tax positions included accrued interest and penalties of $1.9 million. The following tax years remain open to examination and adjustment in the Company's three major tax jurisdictions: Peru: 2011 and all subsequent years U.S.: 2011 and all subsequent years Mexico: 2011 and all subsequent years Management does not expect that any of the open years will result in a cash payment within the upcoming twelve months ending December 31, 2017. The Company's reasonable expectations about future resolutions of uncertain items did not materially change during the year ended December 31, 2016. |

WORKERS' PARTICIPATION: | |
WORKERS' PARTICIPATION: | NOTE 9—WORKERS' PARTICIPATION: The Company's operations in Peru and Mexico are subject to statutory workers' participation. In Peru, the provision for workers' participation is calculated at 8% of pre-tax earnings. The current portion of this participation, which is accrued during the year, is based on the Peruvian Branch's taxable income and is distributed to workers following determination of final results for the year. The annual amount payable to an individual worker is capped at the worker's salary for an 18 month period. Amounts determined in excess of the 18 months of worker's salary is no longer made as a payment to the worker and is levied first for the benefit of the "Fondo Nacional de Capacitacion Laboral y de Promocion del Empleo" (National Workers' Training and Employment Promotion Fund) until this entity receives from all employers in its region an amount equivalent to 2,200 Peruvian taxable units (approximately $2.6 million in 2016). Any remaining excess is levied as payment for the benefit of the regional governments. These levies fund worker training, employment promotion, entrepreneurship and various other programs. In Mexico, workers' participation is determined using the guidelines established in the Mexican income tax law at a rate of 10% of pre-tax earnings as adjusted by the tax law. In December 2013, the Mexican Congress approved some amendments to the tax law, as consequence the Company recorded a deferred workers' participation provision of $16.3 million in 2014. The provision for workers' participation is allocated to "Cost of sales (exclusive of depreciation, amortization and depletion)" and to "selling, general and administrative" in the consolidated statement of earnings, proportional to the number of workers in the production and administrative areas, respectively.

ASSET RETIREMENT OBLIGATION: | |
ASSET RETIREMENT OBLIGATION: | NOTE 10—ASSET RETIREMENT OBLIGATION: The Company maintains an estimated asset retirement obligation for its mining properties in Peru, as required by the Peruvian Mine Closure Law. In accordance with the requirements of this law, the Company's closure plans were approved by the Peruvian Ministry of Energy and Mines ("MINEM"). As part of the closure plans, the Company is required to provide annual guarantees over the estimated life of the mines, based on a present value approach, and to furnish the funds for the asset retirement obligation. This law requires a review of closing plans every five years. Currently and for the near-term future, the Company has pledged the value of its Lima office complex as support for this obligation. The accepted value of the Lima office building for this purpose is $30.8 million. Through January 2017, the Company has provided guarantees of $26.9 million. The closure cost recognized for this liability includes the cost, as outlined in its closure plans, of dismantling the Toquepala and Cuajone concentrators, the smelter and refinery in Ilo, and the shops and auxiliary facilities at the three units. In 2015, we added $12.5 million related to the Toquepala expansion closure plan. In 2014, the Company reviewed ASC 410-20 Asset Retirement Obligation and adjusted the liability by $36.3 million at its Peruvian operations. A comparable adjustment was applied against the deferred asset recognized in property. The net effect of these adjustments did not change the Company's net income. In 2010, the Company announced to the Mexican federal environmental authorities its closure plans for the copper smelter plant at San Luis Potosi. In order to transform an environmental liability into an asset, the Company initiated a program for plant demolition and soil remediation with a budget of $66.2 million, of which the Company has spent $66.0 million through December 31, 2016. Plant demolition and construction of a confinement area at the south of the property were completed in 2012. In accordance with remediation goals previously approved by environmental authorities, soil remediation and on-site encapsulation on a second confinement area of impacted soils have been completed. Confirmation sampling was successfully completed. On September 2, 2016, the environmental authorities approved the conclusion of the remediation effort. The Company is currently studying the possibilities for this property in order to decide whether to sell or develop the property. The overall cost recognized for mining closure in Mexico includes the estimated costs of dismantling concentrators, smelter and refinery plants, shops and other facilities. In 2016, we added $9.5 million related to the Quebalix IV closure plan, a project that is part of the Buenavista expansion. The following table summarizes the asset retirement obligation activity for years ended December 31, 2016 and 2015 (in millions): 2016 2015 Balance as of January 1 $ $ Changes in estimates — Additions Closure payments ) ) Accretion expense ​ ​ ​ ​ ​ ​ ​ ​ Balance as of December 31, $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ |

At December 31, 2016, Minera Mexico was in compliance with this covenant. Between July 2005 and November 2012 the Company issued senior unsecured notes six times totaling $4.2 billion, as listed above. Interest on the notes is paid semi-annually in arrears. The notes rank pari passu with each other and rank pari passu in right of payment with all of the Company's other existing and future unsecured and unsubordinated indebtedness. On April 20, 2015, the Company issued $2.0 billion of fixed-rate senior unsecured notes. This debt was issued in two tranches, $500 million due 2025 at an annual interest rate of 3.875% and $1.5 billion due 2045 at an annual interest rate of 5.875%. These notes are general unsecured obligations of the Company and rank equally with all of its existing and future unsecured and unsubordinated debt. Net proceeds are being used for general corporate purposes, including the financing of the Company´s capital investment program. The notes were issued with an underwriters' discount of $20.2 million. Additionally, issuance costs of $11.8 million associated with these notes were paid and deferred. The unamortized balance of the discount and the costs are presented net of the carrying value of the debt issued and are amortized as interest expense over the life of the loan. The indentures relating to the notes contain certain restrictive covenants, including limitations on liens, limitations on sale and leaseback transactions, rights of the holders of the notes upon the occurrence of a change of control triggering event, limitations on subsidiary indebtedness and limitations on consolidations, mergers, sales or conveyances. Certain of these covenants cease to be applicable before the notes mature if the Company obtains an investment grade rating. The Company obtained investment grade rating in 2005. The Company has registered these notes under the Securities Act of 1933, as amended. The Company may issue additional debt from time to time pursuant to certain of the indentures. If the Company experiences a "Change of Control Triggering Event", the Company must offer to repurchase the notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any. A Change of Control Trigger Event means a Change of Control (as defined) and a rating decline (as defined), that is, if the rating of the notes, by at least one of the rating agencies shall be decreased by one or more gradations. At December 31, 2016, the Company was in compliance with the covenants of the notes. Aggregate maturities of the outstanding borrowings at December 31, 2016, are as follows: Years Principal Due(*) (in millions) 2017 $ — 2018 — 2019 — 2020 2021 — Thereafter ​ ​ ​ ​ ​ Total $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (*) Total debt maturities do not include the debt discount valuation account of $97.0 million. |

BENEFIT PLANS: | NOTE 12—BENEFIT PLANS: Post retirement defined benefit plans The Company has two noncontributory defined benefit pension plans covering former salaried employees in the United States and certain former expatriate employees in Peru (the "Expatriate Plan"). Effective October 31, 2000, the Board of Directors amended the qualified pension plan to suspend the accrual of benefits. In October 2014, the Society of Actuaries ("SOA") issued new mortality tables based on a comprehensive study of private retirement plans. Effective December 31, 2014, the Company elected to update the mortality assumption to the new SOA tables. In addition, the Company's Mexican subsidiaries have a defined contribution pension plan for salaried employees and a non-contributory defined benefit pension plan for union employees (the "Mexican Plan"). The components of net periodic benefit costs calculated in accordance with ASC 715 "Compensation retirement benefits," using December 31 as a measurement date, consist of the following: Years ended (in millions) 2016 2015 2014 Service cost $ $ $ Interest cost Expected return on plan assets ) ) ) Amortization of transition assets, net Amortization of net actuarial loss — ) ) Settlement / Curtailment ) — — Amortization of net loss/(gain) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net periodic benefit cost $ ) $ ) $ ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The change in benefit obligation and plan assets and a reconciliation of funded status are as follows: As of (in millions) 2016 2015 Change in benefit obligation: Projected benefit obligation at beginning of year $ $ Service cost Interest cost Settlement ) — Benefits paid ) ) Actuarial (gain)/loss Actuarial gain assumption changes ) ) Inflation adjustment ) ) ​ ​ ​ ​ ​ ​ ​ ​ Projected benefit obligation at end of year $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Change in plan assets: Fair value of plan assets at beginning of year $ $ Actual return on plan assets ) Employer contributions ) ) Benefits paid ) ) Currency exchange rate adjustment ) ) ​ ​ ​ ​ ​ ​ ​ ​ Fair value of plan assets at end of year $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Funded status at end of year: $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ASC-715 amounts recognized in statement of financial position consists of: Non-current assets $ $ ​ ​ ​ ​ ​ ​ ​ ​ Total $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ASC-715 amounts recognized in accumulated other comprehensive income (net of income taxes of $(3.3) million and $(3.2) million in 2016 and 2015, respectively) consists of: Net loss (gain) $ $ Prior service cost ​ ​ ​ ​ ​ ​ ​ ​ Total $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The following table summarizes the changes in accumulated other comprehensive income for the years ended December 31, related to the defined benefit pension plan, net of income tax: (in millions) 2016 2015 Reconciliation of accumulated other comprehensive income: Accumulated other comprehensive income at beginning of plan year $ $ Net loss/(gain) amortized during the year ) Net loss/(gain) occurring during the year Amortization of transition obligation . ) Currency exchange rate adjustment ) ​ ​ ​ ​ ​ ​ ​ ​ Net adjustment to accumulated other comprehensive income (net of income taxes of $(3.3) million and $(3.6) million in 2016 and 2015, respectively) ​ ​ ​ ​ ​ ​ ​ ​ Accumulated other comprehensive income at end of plan year $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The following table summarizes the amounts in accumulated other comprehensive income amortized and recognized as a component of net periodic benefit cost in 2016 and 2015, net of income tax: (in millions) 2016 2015 Net loss / (gain) $ $ Amortization of net (loss) gain ) Amortization of transition obligation — ) ​ ​ ​ ​ ​ ​ ​ ​ Total amortization expenses $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The assumptions used to determine the pension obligations are: Expatriate Plan 2016 2015 2014 Discount rate % % % Expected long-term rate of return on plan asset % % % Rate of increase in future compensation level N/A N/A N/A Mexican Plan(*) 2016 2015 2014 Discount rate % % % Expected long-term rate of return on plan asset % % % Rate of increase in future compensation level % % % (*) These rates are based on Mexican pesos as pension obligations are denominated in pesos.

Plan assets are invested in a group annuity contract with Metropolitan Life Insurance Company ("MetLife"). The Contract invests in the MetLife General Account Payment Fund (the "Money Fund") and the MetLife Broad Market Bond Fund (the "Bond Fund") managed by BlackRock, Inc. The Money Fund seeks to earn interest and maintain a $1.00 per share net asset value, by investing in U.S. Dollar-denominated money market securities. The Bond Fund seeks to outperform the Bloomberg Barclays ® U.S. Aggregate Bond Index, net of fees, over a full market cycle. The Bond Fund invests in publicly traded, investment grade securities. These may include corporate securities, mortgage securities, treasuries and cash, agency securities, commercial mortgage backed securities and other investment vehicles adhering to the fund's investment objectives. These investments are classified as Level 1 because they are valued using quoted prices of the same securities as they consist of instruments which are publicly traded. Plan assets are invested with the objective of maximizing returns with an acceptable level of risk and maintaining adequate liquidity to fund expected benefit payments. The Company's policy for determining asset mix-targets to meet investment objectives includes periodic consultation with recognized third party investment consultants. The expected long-term rate of return on plan assets is reviewed annually, taking into consideration asset allocations, historical returns and the current economic environment. Based on these factors the Company expects its assets will earn an average of 4.50% per annum assuming its long-term mix will be consistent with its current mix. Mexican Plan Minera Mexico's policy for determining asset mix targets includes periodic consultation with recognized third party investment consultants. The expected long-term rate of return on plan assets is updated periodically, taking into consideration assets allocations, historical returns and the current economic environment. The fair value of plan assets is impacted by general market conditions. If actual returns on plan assets vary from the expected returns, actual results could differ. The plan assets are managed by three financial institutions, Scotiabank Inverlat S.A., Banco Santander and Banco Mercantil del Norte, S.A. 78% of the funds are invested in Mexican government securities, including treasury certificates and development bonds of the Mexican government. The remaining 22% is invested in common shares of Grupo Mexico. The plan assets are invested without restriction in active markets that are accessible when required and are therefore considered as level 1, in accordance with ASC 820 "Fair Value Measurement." These plans accounted for approximately 30% of benefit obligations. The following table represents the asset mix of the investment portfolio as of December 31: 2016 2015 Asset category: Equity securities % % Treasury bills % % ​ ​ ​ ​ ​ ​ ​ ​ % % ​ ​ ​ ​ ​ ​ ​ ​ The amount of contributions that the Company expects to pay to the plan during 2017 is $1.3 million, which excludes $3.4 million of pending payments to former Buenavista workers. Post-retirement Health Care Plan: Peru: The Company adopted a post-retirement health care plan for retired salaried employees eligible for Medicare in 1996. The Company manages the plan and is currently providing health benefits to retirees. The plan is accounted for in accordance with ASC 715 "Compensation retirement benefits." Mexico: Through 2007, the Buenavista unit provided health care services free of charge to employees and retired unionized employees and their families through its own hospital at the Buenavista unit. In 2011, the Company signed an agreement with the Secretary of Health of the State of Sonora to provide these services to its retired workers and their families. The new workers of Buenavista will receive health services through the Mexican Institute of Social Security as is the case for all Mexican workers.

COMMITMENTS AND CONTINGENCIES: | NOTE 13—COMMITMENTS AND CONTINGENCIES: Environmental matters: The Company has instituted extensive environmental conservation programs at its mining facilities in Peru and Mexico. The Company's environmental programs include, among others, water recovery systems to conserve water and minimize the impact on nearby streams, reforestation programs to stabilize the surface of the tailings dams and the implementation of scrubbing technology in the mines to reduce dust emissions. Environmental capital investments in years 2016, 2015 and 2014, were as follows (in millions): 2016 2015 2014 Peruvian operations $ $ $ Mexican operations ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Peruvian operations : The Company's operations are subject to applicable Peruvian environmental laws and regulations. The Peruvian government, through the Ministry of Environment ("MINAM") conducts annual audits of the Company's Peruvian mining and metallurgical operations. Through these environmental audits, matters related to environmental obligation, compliance with legal requirements, atmospheric emissions, effluent monitoring and waste management are reviewed. The Company believes that it is in material compliance with applicable Peruvian environmental laws and regulations. Peruvian law requires that companies in the mining industry provide assurances for future mine closure and remediation. In accordance with the requirements of this law, the Company's closure plans were approved by MINEM. See Note 10 "Asset retirement obligation," for further discussion of this matter. In accordance with the requirements of the law, in 2015 the Company submitted the closure plans for the Tia Maria project and for the Toquepala expansion. The process of review and approval of closure plans usually takes several months. In March 2016, MINEM approved the Mining Closure Plan for the Toquepala expansion project. The closure plan for the Tia Maria project is pending approval. In 2008, the Peruvian government enacted environmental regulations establishing more stringent air quality standards ("AQS") for daily sulfur dioxide ("SO2") in the air for the Peruvian territory. These regulations, as amended in 2013, recognize distinct zones/areas, as atmospheric basins. MINAM has established three atmospheric basins that require further attention to comply with the air quality standards. The Ilo basin is one of these three areas and the Company's smelter and refinery are part of the area. A supreme decree issued on April 8, 2014, indicates that mining companies should review their compliance with these regulations and develop a modification plan to reach compliance. At December 31, 2016, the Company continues to work with an environmental technical study group, established by a MINAM resolution to identify activities, goals, deadlines, timetables and to develop an action plan in order to achieve compliance with AQS. While the Company believes that a potential loss contingency may exist, it cannot currently estimate the amount of such contingency. The Company and other industries affected by this supreme decree believe that the lack of further regulations and direction from the government has delayed the full review and analysis of the necessary actions to establish compliance. Pending further government action, the Company will continue to work with its study group to analyze this issue. Furthermore, the Company does not believe it can estimate a reasonable range of possible costs until additional guidance is received from the government. Therefore, currently the Company is not able to disclose a range of costs that is meaningful. In 2013, the Peruvian government enacted new soil environmental quality standards ("SQS") applicable to any existing facility or project that generates or could generate risk of soil contamination in its area of operation or influence. In March 2014, MINAM issued a supreme decree, which establishes additional provisions for the gradual implementation of SQS. Under this rule the Company had twelve months to identify contaminated sites in and around its facilities and present a report of identified contaminated sites. This report was submitted to MINEM in April 2015. After a review, MINEM should evaluate and issue a report to the Company, which will allow it to continue to the next phase. At December 31, 2016, the Company is awaiting an official response from MINEM. Once MINEM notifies the Company, it must prepare a characterization study to determine the depth, extent and physio-chemical composition of the contaminated areas and to define an appropriate remediation plan and the time-frame in which it will take place. In addition, the Company must submit for approval a Soil Decontamination Plan (SDP) within 24 months after being notified by the authority. This SDP shall include remediation actions, a schedule and compliance deadlines. Also under this rule, if deemed necessary and given reasonable justification, the Company may request a one year extension for the decontamination plan. Soil confirmation tests must be carried out after completion of decontamination actions (within the approved schedule) and results must be presented to authorities within 30 days after receiving such results. Non-compliance with this obligation or with decontamination goals will carry penalties, although no specific sanctions have been established yet. During compliance with this schedule, companies cannot be penalized for non-compliance with the SQS. While the Company believes that there is a reasonable possibility that a potential loss contingency may exist, it cannot currently estimate the amount of the contingency. The Company believes that a reasonable determination of the loss will be possible once the characterization study and the SDP are substantially completed. At that time the Company will be in a position to estimate the remediation cost. Further, the Company does not believe that it can estimate a reasonable range of possible costs until the noted studies have substantially progressed and therefore is not be able to disclose a range of costs that is meaningful. Mexican operations : The Company's operations are subject to applicable Mexican federal, state and municipal environmental laws, to Mexican official standards, and to regulations for the protection of the environment, including regulations relating to water supply, water quality, air quality, noise levels and hazardous and solid waste. The principal legislation applicable to the Company's Mexican operations is the Federal General Law of Ecological Balance and Environmental Protection (the "General Law"), which is enforced by the Federal Bureau of Environmental Protection ("PROFEPA"). PROFEPA monitors compliance with environmental legislation and enforces Mexican environmental laws, regulations and official standards. It may also initiate administrative proceedings against companies that violate environmental laws, which in the most extreme cases may result in the temporary or permanent shutdown of non-complying facilities, the revocation of operating licenses and/or other sanctions or fines. In 2011, the General Law was amended, giving an individual or entity the ability to contest administrative acts, including environmental authorizations, permits or concessions granted, without the need to demonstrate the actual existence of harm to the environment as long as it can be argued that the harm may be caused. In addition, in 2011, amendments to the Civil Federal Procedures Code ("CFPC") were enacted. These amendments establish three categories of collective actions by means of which 30 or more people claiming injury derived from environmental, consumer protection, financial services and economic competition issues will be considered to be sufficient in order to have a legitimate interest to seek through a civil procedure restitution or economic compensation or suspension of the activities from which the alleged injury derived. The amendments to the CFPC may result in more litigation, with plaintiffs seeking remedies, including suspension of the activities alleged to cause harm. In 2013, the Environmental Liability Federal Law was enacted. The law establishes general guidelines for actions to be considered to likely cause environmental harm. If a possible determination regarding harm occurs, environmental clean-up and remedial actions sufficient to restore environment to a pre-existing condition should be taken. Under this law, if restoration is not possible, compensation measures should be provided. Criminal penalties and monetary fines can be assessed under this law. On August 6, 2014, an accidental spill of approximately 40,000 cubic meters of copper sulfate solution occurred at a leaching pond that was under construction ten kilometers from the mine of Buenavista del Cobre, S.A. de C.V. ("BVC") a subsidiary of the Company. The accident was caused by a rock collapse that affected the system's pumping station and by a construction defect in the seal of a pipe in the leaching system containment dam, a part of the new SX-EW III plant. This solution reached the Bacanuchi River and the Sonora River. Immediate actions were taken in order to contain the spill, and to comply with all the legal requirements. In August 2014, the Company hired contractors including environmental specialists and more than 1,200 of its own workers to clean the river. In addition, the Company developed a service program to assist the residents of the Sonora River region, which included (i) water distribution provisions, and infrastructure development within the affected region, (ii) the expansion of the current Community Development program to communities further downstream that were affected and previously not within the scope of the Company´s program, (iii) meetings with local farmers and producers in coordination with the Federal Ministry of Agriculture, Livestock, Rural Development, Fisheries, and Nutrition in order to revamp and promote the activities of local farmers and producers, (iv) the implementation of sustainable productive projects at each affected site, as well as (v) the establishment of service desks to address specific complaints and concerns of the community. The National Water Commission, the Federal Commission for the Protection of Sanitary Risk and PROFEPA initiated administrative proceedings regarding the spill to determine possible environmental and health damages. On August 19, 2014, PROFEPA, as part of the administrative proceeding initiated after the spill, announced the filing of a criminal complaint against BVC in order to determine those responsible for the environmental damages. The Company is vigorously defending itself against this complaint. As of December 31, 2016, the case remains in the procedural stages and is pending resolution. On September 15, 2014, BVC executed an administrative agreement with PROFEPA, providing for the submission of a remediation action plan to the Mexican Ministry of Environment and Natural Resources (Secretaria de Medio Ambiente y Recursos Naturales "SEMARNAT"). The general remediation program submitted to SEMARNAT was approved on January 6, 2015. This program is being developed in five different zones all of which have obtained approval from SEMARNAT. The Company is complying with the remedial program. The Company also created a trust with Nacional Financiera S.N.C., a Mexican development bank, acting as a Trustee to support environmental remedial actions in connection with the spill, to comply with the remedial action plan and to compensate those persons adversely affected by the spill. The Company committed up to two billion Mexican pesos (approximately $150 million) of which approximately one billion Mexican pesos have already been contributed. A technical committee for the trust was created with representatives from the federal government, the Company and specialists assisted by a team of environmental experts to ensure the proper use of the funds. Along with the administrative agreement executed with PROFEPA, the trust serves as an alternative mechanism for dispute resolution to mitigate public and private litigation risks. As a result of the administrative proceeding, conducted by PROFEPA, on March 2, 2015 a final ruling imposed a fine of $1.7 million. Through the first half of 2015, six collective action lawsuits were filed in federal courts in Mexico City and Sonora against two subsidiaries of the Company seeking economic compensation, clean up and remedial activities in order to restore the environment to its pre-existing conditions. Four of the collective action lawsuits have been dismissed by the court. The plaintiffs in these six lawsuits are: Acciones Colectivas de Sinaloa, A.C. which established two collective actions (one of which was dismissed on September 26, 2016); Filiberto Navarro Soto et al (dismissed on July 14, 2015); Defensa Colectiva A.C. (dismissed on August 7, 2015); Ismael Navarro Babuca et al (dismissed on August 17, 2015); and Ana Luisa Salazar Medina et al. which has been granted a collective action certification and the plaintiffs have requested cautionary measures on the construction of facilities for the monitoring of public health services and the prohibition of the closure of the RÃo Sonora Trust. For a description of the regulations related to collective actions in Mexico, please refer to the 2011 amendments to the CFPC described above. Similarly, during 2015, eight civil action lawsuits were filed against BVC in the state courts of Sonora seeking damages for alleged injuries and for moral damages as a consequence of the spill. The plaintiffs in the state court lawsuits are: Jose Vicente Arriola Nunez et al; Santana Ruiz Molina et al; Andres Nogales Romero et al; Teodoro Javier Robles et al; Gildardo Vasquez Carvajal et al; Rafael Noriega Souffle et al; Grupo Banamichi Unido de Sonora El Dorado, S.C. de R.L. de C.V; and Marcelino Mercado Cruz. In the first quarter of 2016, one additional civil action lawsuit, claiming the same damages, was filed by Juan Melquicedec Lebaron. Additionally, during the second half of 2016, two additional civil action lawsuits, claiming the same damages, were filed by Blanca Lidia Valenzuela Rivera et al and Ramona Franco Quijada et al. During 2015, four constitutional lawsuits (juicios de amparo) were filed before Federal Courts against various authorities and against a subsidiary of the Company, arguing; (i) the alleged lack of a waste management program approved by SEMARNAT; (ii) the alleged lack of a remediation plan approved by SEMARNAT with regard to the August 2014 spill; (iii) the alleged lack of community approval regarding the environmental impact authorizations granted by SEMARNAT to one subsidiary of the Company; and (iv) the alleged inactivity of the authorities with regard of the spill in August 2014. The plaintiffs of those lawsuits are: Francisca Garcia Enriquez, et al which established two lawsuits, Francisco Ramon Miranda, et al and Jesus David Lopez Peralta et al. In the first quarter of 2016, an additional constitutional lawsuit, claiming same damages was filed by Oscar Encinas Gamez et al (dismissed in December, 2016); and during the third quarter of 2016, three additional constitutional lawsuits, claiming same damages were filed by Maria Elena Heredia Bustamante et al; Martin Eligio Ortiz Gamez et al; and Maria de los Angeles Enriquez Bacame et al. It is currently not possible to determine the extent of the damages sought in these state and federal lawsuits but the Company considers that these lawsuits are without merit. Accordingly, the Company is vigorously defending against these actions. Nevertheless, the Company considers that none of the legal proceedings resulting from the spill, individually or in the aggregate, would have a material effect on its financial position or results of operations. As of December 31, 2016, BVC estimated total damages at $136.4 million, of which $42.5 million was paid with the Company's funds, and approximately one billion Mexican pesos (approximately $74.9 million) was deposited in the trust. These funds have been available and are being used to compensate claims as they arise. This deposit was classified as restricted cash and was recorded as an operating expense in the Company's results. On December 1, 2016, SEMARNAT issued its final resolution which established that all remediation actions contained in the Remediation Plan, as approved by the same authority, have been fully complied with no pending obligations according to such Plan, except for biological monitoring activities at the Sonora river that will be continued until the first semester of 2019. Also, on January 26, 2017, PROFEPA issued its final resolution under which it declared all mitigation actions as complete and its investigation procedure is definitely closed. In light of the above, the Company has obtained all necessary formal decisions from SEMARNAT and PROFEPA. On February 7, 2017, the Company proceeded to close the trust created with the purpose of complying with all remediation activities. Therefore, this matter is closed. The Company believes that all of its facilities in Peru and Mexico are in material compliance with applicable environmental, mining and other laws and regulations. The Company also believes that continued compliance with environmental laws of Mexico and Peru will not have a material adverse effect on the Company's business, properties, result of operations, financial condition or prospects and will not result in material capital investments. Litigation matters : Garcia Ataucuri and Others against SCC's Peruvian Branch : In April 1996, the Branch was served with a complaint filed in Peru by Mr. Garcia Ataucuri and approximately 900 former employees seeking the delivery of a substantial number of "labor shares" (acciones laborales) plus dividends on such shares, to be issued to each former employee in proportion to their time of employment with SCC's Peruvian Branch, pursuant to a former Peruvian mandated profit sharing law. The labor share litigation is based on claims of former employees for ownership of labor shares that the plaintiffs state that the Branch did not issue during the 1970s until 1979 under such former Peruvian mandated profit sharing law. In 1971, the Peruvian government enacted legislation providing that mining workers would have a 10% participation in the pre-tax profits of their employing enterprises. This participation was distributed 40% in cash and 60% in an equity interest of the enterprise. In 1978, the equity portion, which was originally delivered to a mining industry workers' organization, was set at 5.5% of pre-tax profits and was delivered, mainly in the form of "labor shares" to individual workers. The cash portion was set at 4.0% of pre-tax earnings and was delivered to individual employees also in proportion to their time of employment with the Branch. In 1992, the workers' participation was set at 8%, with 100% payable in cash and the equity participation was eliminated from the law. In relation to the issuance of "labor shares" by the Branch in Peru, the Branch is a defendant in the following lawsuits: 1) Mr. Garcia Ataucuri seeks delivery, to himself and each of the approximately 900 former employees of the Peruvian Branch, of the 3,876,380,679.65 old soles or 38,763,806.80 "labor shares" (acciones laborales), as required by Decree Law 22333 (a former profit sharing law), to be issued proportionally to each former employee in accordance with the time of employment of such employee with SCC's Branch in Peru, plus dividends on such shares. The 38,763,806.80 labor shares sought in the complaint, with a face value of 100.00 old soles each, represent 100% of the labor shares issued by the Branch during the 1970s until 1979 for all of its employees during that period. The plaintiffs do not represent 100% of the Branch's eligible employees during that period. It should be noted that the lawsuit refers to a prior Peruvian currency called "sol de oro" or old soles, which was later changed to the "inti", and then into today's "sol". Due to a past period of high inflation between 1985 and 1990, one billion of old soles is equivalent to today's one sol. After lengthy proceedings before the civil courts in Peru on September 19, 2001, on appeal by the Branch, the Peruvian Supreme Court annulled the proceedings noting that the civil courts lacked jurisdiction and that the matter had to be decided by a labor court (the "2000 appeal"). In October 2007, in a separate proceeding initiated by the plaintiffs, the Peruvian Constitutional Court nullified the September 19, 2001 Peruvian Supreme Court decision and ordered the Supreme Court to decide again on the merits of the case accepting or denying the 2000 appeal. In May 2009, the Supreme Court rejected the 2000 appeal of the Branch affirming the adverse decision of the appellate civil court and lower civil court. While the Supreme Court has ordered SCC's Peruvian Branch to deliver the labor shares and dividends, it has clearly stated that SCC's Peruvian Branch may prove, by all legal means, its assertion that the labor shares and dividends were distributed to the former employees in accordance with the profit sharing law then in effect, an assertion which SCC's Peruvian Branch continues to make. On June 9, 2009, the Branch filed a proceeding of relief before a civil court in Peru seeking the nullity of the 2009 Supreme Court decision and, in a separate proceeding, a request for a precautionary measure. The civil court rendered a favorable decision on the nullity and the precautionary measure, suspending the enforcement of the Supreme Court decision, for the reasons indicated above and other reasons. In February 2012, the Branch was notified that the civil court had reversed its prior decisions. On appeal by the Peruvian Branch the Superior Court affirmed the lower court's decisions regarding the nullity of the 2009 Supreme Court decision and the precautionary measure. As a result, the nullity of the precautionary measure became final and is not appealable. However, the nullity of the 2009 Supreme Court decision was appealed by the Branch before the Constitutional Court. On April 10, 2014, the Constitutional Court denied the Company's appeal and affirmed the lower court's decision. On September 23, 2015, the lower court that ordered the delivery by the Branch of the labor shares, seized 10,501,857 investment shares owned by SCC and Compañia Minera Los Tolmos, S.A. ("Los Tolmos"). The Company is vigorously defending against these measures, and has challenged them on various grounds, mainly because a "labor share" created by law in 1979 is not equivalent to an "investment share", on a one to one basis, as the latter must recognize the Peruvian inflation of the 1980-2014 period. One "investment share" represents ten million "labor shares". Additionally, the seized investment shares are owned by SCC and Los Tolmos, companies that are not a party in the lawsuit. In December 2015, the Company appealed the lower court´s decision before the Superior Court that declared without merit its opposition to the seizure. Los Tolmos initiated a third party claim to ownership, to have the lower court cancel the seizure order on their investment shares. In January 2016, the lower court issued a resolution clarifying that the seizure measure applies to the investment shares owned by SCC's Peruvian Branch even if they are in possession of SCC or Los Tolmos. On October 4, 2016, the Superior Court issued Resolution N°10 which ruled that the seizure of the corporation´s investment shares to Los Tolmos in 2015 was unfounded. To reach this assertion, the Lima Superior Court recognizes that the labor shares have suffered variations in their denomination and face value, due to the currency changes suffered in Peru since 1985 to 1991, for which a first share exchange was made at a rate of 10 to 1, and later at a rate of 1,000 to 1. The Court also indicated that SCC's assertion that the plaintiffs had participated in each of the labor share exchange transactions has not been proven. Accordingly, the judge in charge of the case must define this situation and determine (a) which plaintiffs received the labor shares to determine who are the holders of the current investment share certificates, (b) who have sold their shares, (c) determine the dividend amounts that have been generated by such shares and identify the plaintiffs who have collected the dividends, and (d) review the shares ledger. The judge ordered that an expert be appointed to assist in defining these items. In addition, Resolution N° 10 also ruled that the value and proportion of the 10,185,700 labor shares represented by the plaintiffs must be mathematically determined in respect to the total of 57,649,479 current investment shares issued by the Branch. The Company considers that the Superior Court's decision is important because it recognizes that the value of the original labor shares was affected by the fluctuations in Peruvian currency, which changed over time from the original "sol de oro" to the "inti", and subsequently to the "Nuevo sol" or currently simply referred to the "sol". Such fluctuation affected the value of a Labor share. SCC's Peruvian Branch believes that the review by an expert will establish that the labor shares ordered to be paid by the Court are not equivalent on a one to one ratio to the current investment shares, as well as to prove the Company's delivery of the labor shares to some of the plaintiffs. The Court did not define the amount to be paid, however, taking into account the effect of currency fluctuation, the Company expects that the final amount of this contingency will not be material. 2) In addition to the aforementioned lawsuits, the following lawsuits have been filed against SCC's Branch, involving approximately 800 plaintiffs, which seek the same number of labor shares as in the Garcia Ataucuri case, plus interest, labor shares resulting from capital increases and dividends: (1) Armando Cornejo Flores and others v. SCC's Peruvian Branch (filed May 10, 2006); (2) Alejandro Zapata Mamani and others v. SCC's Peruvian Branch (filed June 27, 2008); (3) Edgardo Garcia Ataucuri, in representation of 216 of SCC's Peruvian Branch former workers, v. SCC's Peruvian Branch (filed May 2011); (4) Juan Guillermo Oporto Carpio v. SCC's Peruvian Branch (filed August 2011); (5) Rene Mercado Caballero v. SCC's Peruvian Branch (filed November 2011); (6) Enrique Salazar Alvarez and others v. SCC's Peruvian Branch (filed December 2011); (7) Armando Cornejo Flores, in representation of 37 of SCC's Peruvian Branch former workers v. SCC's Peruvian Branch (filed March 2012); (8) Porfirio Ochochoque Mamani and others v. SCC's Peruvian Branch (filed July 2012); (9) Alfonso Claudio Flores Jimenez and others v. SCC's Peruvian Branch (filed July 2013); (10) Edgardo Garcia Ataucuri in representation of 104 of SCC´s Peruvian Branch former workers (filed March 2015); (11) Nicolas Aurelio Sueros Benavente v. SCC's Peruvian Branch (filed May 2015); (12) Victor Raul Marquez Cano v. SCC's Peruvian Branch (filed June 2015) and (13) Armando Cornejo Flores in representation of five former workers of SCC's Peruvian Branch v. SCC's Peruvian Branch (filed September 2016). SCC's Peruvian Branch has answered the complaints and denied the validity of the asserted claims. SCC's Peruvian Branch asserts that the labor shares were distributed to the former employees in accordance with the profit sharing law then in effect. The Peruvian Branch has not made a provision for these lawsuits because it believes that it has meritorious defenses to the claims asserted in the complaints. The "Virgen Maria" Mining Concessions of the Tia Maria Mining Project The Tia Maria project includes various mining concessions, totaling 32,989.64 hectares. One of the concessions is the "Virgen Maria" mining concession totaling 943.72 hectares or 2.9% of the total mining concessions. Related to the "Virgen Maria" mining concessions, in August 2009, a lawsuit was filed against SCC's Branch by the former stockholders of Exploraciones de Concesiones Metalicas S.A.C. ("Excomet"). The plaintiffs allege that the acquisition of Excomet's shares by the Branch is null and void because the $2 million purchase price paid by the Branch for the shares of Excomet was not fairly negotiated by the plaintiffs and the Branch. In 2005, the Branch acquired the shares of Excomet after lengthy negotiations with the plaintiffs, and after the plaintiffs, which were all the stockholders of Excomet, approved the transaction in a general stockholders' meeting. Excomet was at the time owner of the "Virgen Maria" mining concession. In October 2011, the civil court dismissed the case on the grounds that the claim had been barred by the statute of limitations. On appeal by the plaintiffs, the superior court reversed the lower court's decision and remanded it to the lower court for further proceedings. In August 2015, the lower court dismissed the case on the grounds that the plaintiffs had not proven the alleged unfairness of the negotiations. The plaintiffs appealed this resolution before the Superior Court. In September 2016, the Superior Court confirmed the lower court's resolution and the plaintiffs filed an extraordinary appeal in order to have the case reviewed by the Supreme Court. As of December 31, 2016, the matter is pending resolution. The Company asserts that this lawsuit is without merit and is vigorously defending against it. Additionally, the amount of this contingency cannot be reasonably estimated by management at this time. The Tia Maria Mining Project There are five lawsuits filed against the Peruvian Branch of the Company related to the Tia Maria project. The lawsuits seek (i) to declare null and void the resolution which approved the Environmental Impact Assessment of the project; (ii) the cancellation of the project and the withdrawal of mining activities in the area and (iii) to declare null and void the mining concession application of the Tia Maria project. The lawsuits were filed by Messrs. Jorge Isaac del Carpio Lazo (filed May 22, 2015), Ernesto Mendoza Padilla (filed May 26, 2015), Juan Alberto Guillen Lopez (filed June 18, 2015), Hernan Raul Hatamare Hual (filed August 6, 2015) and Nicolas Belfiore Nicolini (filed November 13, 2015). The Del Carpio Lazio case was rejected by the court of first instance on November 14, 2016. The Plaintiff filed an appeal before the Superior Court on January 3, 2017. As of December 31, 2016, the matter is pending resolution. The Mendoza Padilla case was rejected by the lower court on July 8, 2015. This ruling was confirmed by the Superior Court on June 14, 2016. On July 12, 2016, the case was appealed before the Constitutional Court. As of December 31, 2016, the matter is pending resolution. The Guillen Lopez and Belfiore Nicolini cases are currently before the lower court. As of December 31, 2016, the matter is pending resolution. On October 3, 2016 the lower court ruled that the Hatamare Hual case had expired and declared the case concluded. The Plaintiff has not filed appeal before the Superior Court. On November 16, 2016, the Company´s Peruvian Branch requested for the case to be closed. As of December 31, 2016, the matter is pending resolution. The amount of this contingency cannot be reasonably estimated by management at this time. Special Regional Pasto Grande Project ("Pasto Grande Project") In 2012, the Pasto Grande Project, an entity of the Regional Government of Moquegua, filed a lawsuit against SCC's Peruvian Branch alleging property rights over a certain area used by the Peruvian Branch and seeking the demolition of the tailings dam where SCC's Peruvian Branch has deposited its tailings from the Toquepala and Cuajone operations since 1995. The Peruvian Branch has had title to use the area in question since 1960 and has constructed and operated the tailing dams with proper governmental authorization, since 1995. SCC's Peruvian Branch asserts that the lawsuit is without merit and is vigorously defending against it. Upon a motion filed by the Peruvian Branch, the lower court has included MINEM as a defendant in this lawsuit. MINEM has answered the complaint and denied the validity of the claim. As of December 31, 2016, the case remains pending resolution without further developments. The amount of this contingency cannot be reasonably estimated by management at this time.

Under this plan, participants will receive 1,200 shares of common stock upon election and 1,200 additional shares following each annual meeting of stockholders thereafter. 600,000 shares of Southern Copper common stock have been reserved for this plan. The fair value of the award is measured each year at the date of the grant. In 2016 and 2015 the stock based compensation expense under this plan equaled $0.3 million and $0.4 million, respectively. The plan expired by its terms on January 30, 2017. A 10-year extension of the plan is being submitted for approval by the Company's stockholders at the 2017 Annual Meeting of Stockholders.

Employee Stock Purchase Plan: 2010 Plan: During 2010, the Company offered to eligible employees a stock purchase plan through a trust that acquires series B shares of Grupo Mexico stock for sale to its employees, employees of subsidiaries, and certain affiliated companies. The purchase price was established at 26.51 Mexican pesos (approximately $1.28) for the initial subscription. The terms of this plan are similar to the terms of the prior Employee Stock Purchase Plan. The stock based compensation expense for the years ended December 31, 2016, 2015 and 2014 and the remaining balance of the unrecognized compensation expense under this plan were as follows (in millions): 2016 2015 2014 Stock based compensation expense $ $ $ Unrecognized compensation expense $ $ $ The unrecognized compensation expense under this plan is expected to be recognized over the remaining two year period.

The purchase price was established at 38.44 Mexican pesos (approximately $1.86) for the initial subscription, which expires on January 2023. Every two years employees will be able to acquire title to 50% of the shares paid in the previous two years. The employees will pay for shares purchased through monthly payroll deductions over the eight year period of the plan. At the end of the eight year period, the Company will grant the participant a bonus of 1 share for every 10 shares purchased by the employee. Any future subscription will be at the average market price at the date of acquisition or the grant date. If Grupo Mexico pays dividends on shares during the eight year period, the participants will be entitled to receive the dividend in cash for all shares that have been fully purchased and paid as of the date that the dividend is paid. If the participant has only partially paid for shares, the entitled dividends will be used to reduce the remaining liability owed for purchased shares. In the case of voluntary or involuntary resignation/termination of the employee, the Company will pay to the employee the fair market sales price at the date of resignation of the fully paid shares, net of costs and taxes. When the fair market sales value of the shares is higher than the purchase price, the Company will apply a deduction over the amount to be paid to the employee based on a decreasing schedule specified in the plan. In case of retirement or death of the employee, the Company will render the buyer or his legal beneficiary, the fair market sales value as of the date of retirement or death of the shares effectively paid, net of costs and taxes.

Under this plan, participants will receive incentive cash bonuses which are used to purchase shares of Grupo Mexico which are deposited in a trust. Non-controlling interest: For all the years presented, in the consolidated statement of earnings the income attributable to non-controlling interest is based on the earnings of the Company's Peruvian Branch. The non-controlling interest of the Company's Peruvian Branch is for investment shares. These shares were generated by legislation in place in Peru from the 1970s through 1991; such legislation provided for the participation of mining workers in the profits of the enterprises for which they worked. This participation was divided between equity and cash. The investment shares included in the non-controlling interest on the consolidated balance sheets are the still outstanding equity distributions made to the Peruvian Branch's employees. In prior years, the Company acquired some Peruvian investment shares in exchange for newly issued common shares of the Company and through purchases at market value. These acquisitions were accounted for as purchases of non-controlling interests. The excess paid over the carrying value was assigned to intangible assets and is being amortized based on production. As a result of these acquisitions, the remaining investment shareholders hold a 0.71% interest in the Peruvian Branch and are entitled to a pro rata participation in the cash distributions made by the Peruvian Branch. The shares are recorded as a non-controlling interest in the Company's financial statements. |

FAIR VALUE MEASUREMENT: | |
FAIR VALUE MEASUREMENT: | NOTE 15—FAIR VALUE MEASUREMENT: Subtopic 820-10 of ASC "Fair value measurement and disclosures—Overall" establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under Subtopic 820-10 are described below: Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2—Inputs that are observable, either directly or indirectly, but do not qualify as Level 1 inputs. (i.e., quoted prices for similar assets or liabilities). Level 3—Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The carrying amounts of certain financial instruments, including cash and cash equivalents, accounts receivable (other than accounts receivable associated with provisionally priced sales) and accounts payable approximate fair value due to their short maturities. Consequently, such financial instruments are not included in the following table that provides information about the carrying amounts and estimated fair values of other financial instruments that are not measured at fair value in the consolidated balance sheet as of December 31, 2016 and December 31, 2015 (in millions): At December 31, 2016 At December 31, 2015 Carrying Value Fair Value Carrying Value Fair Value Liabilities: Long-term debt $ $ $ $ Long-term debt is carried at amortized cost and its estimated fair value is based on quoted market prices classified as Level 1 in the fair value hierarchy except for the case of the Yankee bonds which qualify as Level 2 in the fair value hierarchy as they are based on quoted priced in market that are not active.

CONCENTRATION OF RISK: | NOTE 16—CONCENTRATION OF RISK: The Company operates four open-pit copper mines, five underground poly-metallic mines, two smelters and eight refineries in Peru and Mexico and substantially all of its assets are located in these countries. There can be no assurances that the Company's operations and assets that are subject to the jurisdiction of the governments of Peru and Mexico will not be adversely affected by future actions of such governments. Much of the Company's products are exported from Peru and Mexico to customers principally in the United States, Europe, Asia and South America. Financial instruments, which potentially subject the Company to a concentration of credit risk, consist primarily of cash and cash equivalents, short-term investments and trade accounts receivable. The Company invests or maintains available cash with various banks, principally in the United States, Mexico, Europe and Peru, or in commercial papers of highly-rated companies. As part of its cash management process, the Company regularly monitors the relative credit standing of these institutions. At December 31, 2016, SCC had invested its cash and cash equivalents and short-term investments as follows: % in one institution Country $ in million % of total of country of total United States $ % % % Switzerland % % % Peru % % % Mexico % % % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total cash and short-term investment $ % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (1) 97.0% of the Company's cash is in U.S. dollars. During the normal course of business, the Company provides credit to its customers. Although the receivables resulting from these transactions are not collateralized, the Company has not experienced significant problems with the collection of receivables. The Company is exposed to credit loss in cases where the financial institutions with which it has entered into derivative transactions (commodity, foreign exchange and currency/interest rate swaps) are unable to pay when they owe funds as a result of protection agreements with them. To minimize the risk of such losses, the Company only uses highly-rated financial institutions that meet certain requirements. The Company also periodically reviews the creditworthiness of these institutions to ensure that they are maintaining their ratings. The Company does not anticipate that any of the financial institutions will default on their obligations. The Company's largest customers as percentage of accounts receivable and total sales were as follows: 2016 2015 2014 Accounts receivable trade as of December 31, Five largest customers % % % Largest customer % % % Total sales in year Five largest customers % % % Largest customer % % % |

These services are primarily related to accounting, legal, tax, financial, treasury, human resources, price risk assessment and hedging, purchasing, procurement and logistics, sales and administrative and other support services. The Company pays Grupo Mexico for these services and expects to continue these services in the future. The Company's Mexican operations paid fees for freight services provided by Ferrocarril Mexicano, S.A de C.V., for construction services provided by Mexico Proyectos y Desarrollos, S.A. de C.V. and its affiliates, and for drilling services provided by Compañia Perforadora Mexico S.A.P.I. de C.V. All of these companies are subsidiaries of Grupo Mexico. The Company's Mexican operations purchased scrap and other residual copper mineral from Asarco, and power from MGE. Both companies are subsidiaries of Grupo Mexico. In 2005, the Company organized MGE, as a subsidiary of Minera Mexico, for the construction of two power plants to supply power to the Company's Mexican operations. In May 2010, the Company's Mexican operations granted a $350 million line of credit to MGE for the construction of the power plants. That line of credit was due on December 31, 2012 and carried an interest rate of 4.4%. In the first quarter of 2012, Controladora de Infraestructura Energetica Mexico, S. A. de C. V., an indirect subsidiary of Grupo Mexico, acquired 99.999% of MGE through a capital subscription of 1,928.6 million of Mexican pesos (approximately $150 million), reducing Minera Mexico's participation to less than 0.001%. As a consequence of this change in control, MGE became an indirect subsidiary of Grupo Mexico. Additionally, at the same time, MGE paid $150 million to the Company's Mexican operations partially reducing the total debt. At December 31, 2012, the outstanding balance of $184.0 million was restructured as subordinated debt of MGE with an interest rate of 5.75%. In the third quarter of 2016, MGE repaid the outstanding balance of the debt. Related to this loan, the Company recorded interest income of $4.2 million, $9.2 million and $9.4 million in 2016, 2015 and 2014, respectively. In 2012, the Company signed a power purchase agreement with MGE, whereby MGE will supply some of the Company's Mexican operations with power through 2032. MGE completed construction of its first power plant in June 2013 and the second plant in the second quarter of 2014. These plants are natural gas-fired combined cycle power generating units, with a net total capacity of 516.2 megawatts. The first plant began supplying power to the Company in December 2013, and the second plant began to supply power in June 2015. MGE is supplying approximately 12% of its power output to third-party energy users. On August 4, 2014, Mexico Generadora de Energia Eolica S. de R.L. de C.V, an indirect subsidiary of Grupo Mexico, located in Oaxaca, Mexico, acquired Eolica el Retiro. Eolica el Retiro is a windfarm that has 37 wind turbines. This company started operations in January 2014 and started to sell power to IMMSA and other subsidiaries of Grupo Mexico in the third quarter of 2014. Eolica el Retiro is supplying approximately 15% of its power output to IMMSA. The Company sold copper cathodes, rod and anodes, as well as sulfuric acid, silver, gold and lime to Asarco. In addition, the Company received fees for building rental and maintenance services provided to Mexico Proyectos y Desarrollos, S.A. de C.V. and its affiliates and to Perforadora Mexico S.A.P.I de C.V., and for natural gas and services provided by MGE, all subsidiaries of Grupo Mexico.

SEGMENT AND RELATED INFORMATION: | |
SEGMENT AND RELATED INFORMATION: | NOTE 18—SEGMENT AND RELATED INFORMATION: Company management views Southern Copper as having three reportable segments and manages it on the basis of these segments. The reportable segments identified by the Company are: the Peruvian operations, the Mexican open-pit operations and the Mexican underground mining operations segment identified as the IMMSA unit. The three reportable segments identified are groups of mines, each of which constitute an operating segment, with similar economic characteristics, type of products, processes and support facilities, similar regulatory environments, similar employee bargaining contracts and similar currency risks. In addition, each mine within the individual group earns revenues from similar type of customers for their products and services and each group incurs expenses independently, including commercial transactions between groups. Intersegment sales are based on arm's length prices at the time of sale. These may not be reflective of actual prices realized by the Company due to various factors, including additional processing, timing of sales to outside customers and transportation cost. Added to the segment data is information regarding the Company's sales. The segments identified by the Company are: 1. Peruvian operations, which include the Toquepala and Cuajone mine complexes and the smelting and refining plants, including a precious metals plant, industrial railroad and port facilities that service both mines. The Peruvian operations produce copper, with production of by-products of molybdenum, silver and other material. 2. Mexican open-pit operations, which include La Caridad and Buenavista mine complexes and the smelting and refining plants, including a precious metals plant and a copper rod plant and support facilities that service both mines. The Mexican open-pit operations produce copper, with production of by-products of molybdenum, silver and other material. 3. Mexican underground mining operations, which include five underground mines that produce zinc, copper, silver and gold, a coal mine which produces coal and coke, and a zinc refinery. This group is identified as the IMMSA unit. The Peruvian operations include two open-pit copper mines whose mineral output is transported by rail to Ilo, Peru where it is processed at the Company's Ilo smelter and refinery, without distinguishing between the products of the two mines. The resulting product, anodes and refined copper, are then shipped to customers throughout the world. These shipments are recorded as revenue of the Company's Peruvian mines. The Mexican open-pit segment includes two copper mines whose mineral output is processed in the same smelter and refinery without distinguishing between the products of the two mines. The resultant product, anodes and refined copper, are then shipped to customers throughout the world. These shipments are recorded as revenues of the Company's Mexican open-pit mines. The Company has determined that it is necessary to classify the Peruvian open-pit operations as a separate operating segment from the Mexican open-pit operations due to the very distinct regulatory and political environments in which they operate. The Company's Senior Management Officers must consider the operations in each country separately when analyzing results of the Company and making key decisions. The open-pit mines in Peru must comply with stricter environmental rules and must continually deal with a political climate that has a very distinct vision of the mining industry as compared to Mexico. In addition, the collective bargaining agreement contracts are negotiated differently in each of the countries. These key differences result in the Company taking varying decisions with regards to open-pit operations in the two countries. The IMMSA segment includes five mines whose minerals are processed in the same refinery. This segment also includes an underground coal mine. Sales of product from this segment are recorded as revenues of the Company's IMMSA unit. While the Mexican underground mines are subject to a very similar regulatory environment of the Mexican open-pit mines, the nature of the products and processes of two Mexican operations vary distinctly. These differences cause the Company's Senior Management Officers to take a very different approach when analyzing results and making decisions regarding the two Mexican operations. Financial information is regularly prepared for each of the three segments and the results of the Company's operations are regularly reported to Senior Management on the segment basis. Senior Management of the Company focus on operating income and on total assets as measures of performance to evaluate different segments and to make decisions to allocate resources to the reported segments. These are common measures in the mining industry.

These sales are subject to final pricing based on the average monthly copper prices on the London Metal Exchange ("LME") or New York Commodities Exchange ("COMEX") and Dealer Oxide molybdenum prices in the future month of settlement. Following are the provisionally priced copper and molybdenum sales outstanding at December 31, 2016: Sales volume Priced at Month of settlement Copper January through February 2017 Molybdenum January through March 2017 Provisional sales price adjustments included in accounts receivable and net sales were as follows at December, 31 (in millions): At 2016 2015 Copper $ $ ) Molybdenum ) ) ​ ​ ​ ​ ​ ​ ​ ​ Total $ $ ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Management believes that the final pricing of these sales will not have a material effect on the Company's financial position or results of operations. LONG-TERM SALES CONTRACTS: The following are the significant outstanding long-term contracts: In 2013, a long term copper cathodes sales agreement was signed with Mitsui for five years, with shipments beginning in 2015. Mitsui and the Company will negotiate market terms and conditions for annual contracts no later than November 30 of the year prior to shipment. The contract considers the following annual volumes of copper cathodes; 6,000 tons for 2015 and 48,000 tons for each of the years from 2016 through 2019. The contract volume would increase by 24,000 tons the year after Tia Maria reaches full production capacity. Failure to reach an agreement on market terms would cancel the annual contract but not the long-term agreement. Under the terms of the agreement all shipments would be to Asia and there are no exclusivity rights for Mitsui or commissions included. This contract may be renewed for additional five year periods, upon the agreement of both parties. Under the terms of a sales contract with Molibdenos y Metales, S.A., SPCC Peru Branch is required to supply approximately 29,380 tons of molybdenum concentrates from 2016 through 2018. This contract may be extended for one more calendar year during each October to maintain a three year period unless either party decides to terminate the agreement. The sale price of the molybdenum concentrates is based on the monthly average of the high and low Metals Week Dealer Oxide quotation. The roasting charge deduction is agreed based on international market terms. Under the terms of a sales contract with Molymex, S.A. de C.V., Operadora de Minas de Nacozari, S.A. de C.V. and Operadora de Minas e Instalaciones Mineras, S.A. de C. V. are required to supply at least the 80% of their molybdenum concentrates production from 2016 through 2019. The sale price of the molybdenum concentrate is based on the monthly average of the high and low Metals Week Dealer Oxide quotation. The roasting charge deduction is negotiated based on international market terms. |

SUMMARY OF SIGNIFICANT ACCOUN32
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (Policies) | 12 Months Ended |
Dec. 31, 2016 | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: | |
Principles of consolidation | Principles of consolidation— The consolidated financial statements include the accounts of subsidiaries of which the Company has voting control, in accordance with Accounting Standards Codification ("ASC") 810 Consolidation . Such financial statements are prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). |
Use of estimates | Use of estimates— The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include the carrying value of ore reserves that are the basis for future cash flow estimates and amortization calculations; environmental reclamation, closure and retirement obligations; estimates of recoverable copper in mill and leach stockpiles; asset impairments (including estimates of future cash flows); unrecognized tax benefits; valuation allowances for deferred tax assets; and fair value of financial instruments. Management bases its estimates on the Company's historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates. |
Revenue recognition | Revenue recognition— Substantially all of the Company's copper and non-copper products are sold under annual or other longer-term contracts. Revenue is recognized when title passes to the customer. The passing of title is based on terms of the contract, generally upon shipment. Copper and non-copper revenues are determined based on the monthly average of prevailing commodity prices according to the terms of the contracts. The Company provides allowances for doubtful accounts based upon historical bad debt and claims experience and periodic evaluation of specific customer accounts. For certain of the Company's sales of copper and molybdenum products, customer contracts allow for pricing based on a month subsequent to shipping, in most cases within the following three months and occasionally in some cases a few additional months. In such cases, revenue is recorded at a provisional price at the time of shipment. The provisionally priced copper sales are adjusted to reflect forward LME or COMEX copper prices at the end of each month until a final adjustment is made to the price of the shipments upon settlement with customers pursuant to the terms of the contract. In the case of molybdenum sales, for which there are no published forward prices, the provisionally priced sales are adjusted to reflect the market prices at the end of each month until a final adjustment is made to the price of the shipments upon settlement with customers pursuant to the terms of the contract. These provisional pricing arrangements are accounted for separately from the contract as an embedded derivative instrument under ASC 815-30 "Derivatives and Hedging—Cash Flow Hedges." The Company sells copper in concentrate, anode, blister and refined form at industry standard commercial terms. Net sales include the invoiced value of copper, zinc, silver, molybdenum, sulfuric acid and other metals and the corresponding fair value adjustment of the related forward contract of copper and molybdenum. |
Shipping and handling fees and costs | Shipping and handling fees and costs— Amounts billed to customers for shipping and handling are classified as sales. Amounts incurred for shipping and handling are included in cost of sales (exclusive of depreciation, amortization and depletion). |
Cash and cash equivalents | Cash and cash equivalents— Cash and cash equivalents include bank deposits, certificates of deposit and short-term investment funds with original maturities of three months or less at the date of purchase. The carrying value of cash and cash equivalents approximates fair value. |
Short-term investments | Short-term investments— The Company accounts for short-term investments in accordance with ASC 320-10 "Investments Debt and Equity Securities—Recognition." The Company determines the appropriate classification of all short-term investments as held-to-maturity, available-for-sale or trading at the time of purchase and re-evaluates such classifications as of each balance sheet date. Unrealized gains and losses on available-for-sale investments, net of taxes, are reported as a component of accumulated other comprehensive income (loss) in stockholders' equity, unless such loss is deemed to be other than temporary. |
Inventories | Inventories— The Company principally produces copper and, in the production process, obtains several by-products, including molybdenum, silver, zinc, sulfuric acid and other metals. Metal inventories, consisting of work-in-process and finished goods, are carried at the lower of average cost or market. Costs incurred in the production of metal inventories exclude general and administrative costs. Once molybdenum, silver, zinc and other by-products are identified, they are transferred to their respective production facilities and the incremental cost required to complete production is assigned to their inventory value. Work-in-process inventories represent materials that are in the process of being converted into a saleable product. Conversion processes vary depending on the nature of the copper ore and the specific mining operation. For sulfide ores, processing includes milling and concentrating and results in the production of copper and molybdenum concentrates. Finished goods include saleable products (e.g., copper concentrates, copper anodes, copper cathodes, copper rod, molybdenum concentrate and other metallurgical products). Supplies inventories are carried at the lower of average cost or market. |
Long-term inventory - Ore stockpiles on leach pads | Long-term inventory—Ore stockpiles on leach pads. The leaching process is an integral part of the mining operations carried out at the Company's open-pit mines. The Company capitalizes the production cost of leachable material at its Toquepala, La Caridad and Buenavista mines recognizing it as inventory. The estimates of recoverable mineral content contained in the leaching dumps are supported by engineering studies. As the production cycle of the leaching process is significantly longer than the conventional process of concentrating, smelting and electrolytic refining, the Company includes on its balance sheet current leach inventory (included in work-in-process inventories) and long-term leach inventory. Through 2013, the cost attributed to the leach material was charged to cost of sales over a five-year period, which was considered the average estimated recovery period based on the historical recovery percentages of each mine. During the fourth quarter of 2014, the Company completed the construction of a new plant that has resulted in increased efficiency in production and use of leachable material. Accordingly, the Company changed its method of amortization to the units of production method. This change in estimate effected by a change in accounting principle results in a better matching of costs to revenues as a result of the improved production levels from the new plant and results in a better estimate of current and long-term leachable material inventory. |
Property | Property— Property is recorded at acquisition cost, net of accumulated depreciation and amortization. Cost includes major expenditures for improvements and replacements, which extend useful lives or increase capacity and interest costs associated with significant capital additions. Maintenance, repairs, normal development costs at existing mines and gains or losses on assets retired or sold are reflected in earnings as incurred. Buildings and equipment are depreciated on the straight-line method over estimated lives from five to 40 years or the estimated life of the mine if shorter. |
Mine development | Mine development— Mine development includes primarily the cost of acquiring land rights to an exploitable ore body, pre-production stripping costs at new mines that are commercially exploitable, costs associated with bringing new mineral properties into production, and removal of overburden to prepare unique and identifiable areas outside the current mining area for such future production. Mine development costs are amortized on a unit of production basis over the remaining life of the mines. There is a diversity of practices in the mining industry in the treatment of drilling and other related costs to delineate new ore reserves. The Company follows the practices outlined in the next two paragraphs in its treatment of drilling and related costs. Drilling and other associated costs incurred in the Company's efforts to delineate new resources, whether near-mine or Greenfield are expensed as incurred. These costs are classified as mineral exploration costs. Once the Company determines through feasibility studies that proven and probable reserves exist and that the drilling and other associated costs embody a probable future benefit that involves a capacity, singly or in combination with other assets, to contribute directly or indirectly to future net cash inflow, then the costs are classified as mine development costs. These mine development costs incurred prospectively to develop the property are capitalized as incurred, until the commencement of production, and are amortized using the units of production method over estimated life of the ore body. During the production stage, drilling and other related costs incurred to maintain production are included in production cost in the period in which they are incurred. Drilling and other related costs incurred in the Company's efforts to delineate a major expansion of reserves at an existing production property are expensed as incurred. Once the Company determines through feasibility studies that proven and probable incremental reserves exist and that the drilling and other associated costs embody a probable future benefit that involves a capacity, singly or in combination with other assets, to contribute directly or indirectly to future net cash inflow, then the costs are classified as mine development costs. These incremental mine development costs are capitalized as incurred, until the commencement of production and amortized using the units of production method over the estimated life of the ore body. A major expansion of reserves is one that increases total reserves at a property by approximately 10% or more. For the years ended December 31, 2016, 2015 and 2014, the Company did not capitalize any drilling and related costs. |
Asset retirement obligations (reclamation and remediation costs) | Asset retirement obligations (reclamation and remediation costs)— The fair value of a liability for asset retirement obligations is recognized in the period in which the liability is incurred. The liability is measured at fair value and is adjusted to its present value in subsequent periods as accretion expense is recorded. The corresponding asset retirement costs are capitalized as part of the carrying value of the related long-lived assets and depreciated over the asset's useful life. |
Intangible assets | Intangible assets— Intangible assets include primarily the excess amount paid over the book value for investment shares which are presented as mining concessions, and mining and engineering development studies. Intangible assets are carried at acquisition costs, net of accumulated amortization and are amortized principally on a unit of production basis over the estimated remaining life of the mines. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. |
Debt issuance costs | Debt issuance costs— Debt issuance costs related to a recognized debt liability are presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with the treatment of a debt discount. |
Ore reserves | Ore reserves— The Company periodically reevaluates estimates of its ore reserves, which represent the Company's estimate as to the amount of unmined copper remaining in its existing mine locations that can be produced and sold at a profit. Such estimates are based on engineering evaluations derived from samples of drill holes and other openings, combined with assumptions about copper market prices and production costs at each of the respective mines. The Company updates its estimate of ore reserves at the beginning of each year. In this calculation, the Company uses current metal prices which are defined as the average metal price over the preceding three years. The current price per pound of copper, as defined, was $2.61, $2.99 and $3.36 at the end of 2016, 2015 and 2014, respectively. The ore reserve estimates are used to determine the amortization of mine development and intangible assets. Once the Company determines through feasibility studies that proven and probable reserves exist and that the drilling and other associated costs embody a probable future benefit that involves a capacity, singly or in combination with other assets, to contribute directly or indirectly to future net cash inflow, then the costs are classified as mine development costs and the Company discloses the related ore reserves. |
Exploration | Exploration— Tangible and intangible costs incurred in the search for mineral properties are charged against earnings when incurred. |
Income taxes | Income taxes— Provisions for income taxes are based on taxes payable or refundable for the current year and deferred taxes on temporary differences between the amount of taxable income and pretax financial income and between the tax bases of assets and liabilities and their reported amounts in the financial statements. Deferred tax assets and liabilities are included in the financial statements at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized and settled as prescribed in ASC 740 "Income taxes." As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Deferred income tax assets are reduced by any benefits that, in the opinion of management, are more likely not to be realized. The Company's operations involve dealing with uncertainties and judgments in the application of complex tax regulations in multiple jurisdictions. The final taxes paid are dependent upon many factors, including negotiations with taxing authorities in various jurisdictions and resolution of disputes arising from federal, state, and international tax audits. The Company recognizes potential liabilities and records tax liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on its estimate of whether, and the extent to which, additional taxes will be due. The Company follows the guidance of ASC 740 "Income taxes" to record these liabilities. (See Note 8 "Income taxes" of the consolidated financial statements for additional information). The Company adjusts these reserves in light of changing facts and circumstances; however, due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the Company's current estimate of the tax liabilities. If its estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities would result in tax benefits being recognized in the period when the Company determines the liabilities are no longer necessary. The Company classifies income tax-related interest and penalties as income taxes in the financial statements, as well as interest and penalties, if any, related to unrecognized tax benefits. |
Foreign exchange | Foreign exchange— The Company's functional currency is the U.S. dollar. As required by local law, both the Peruvian Branch and Minera Mexico maintain their books of accounts in Peruvian soles and Mexican pesos, respectively. Foreign currency assets and liabilities are remeasured into U.S. dollars at current exchange rates, except for non-monetary items such as inventory, property, intangible assets and other assets which are remeasured at historical exchange rates. Revenues and expenses are generally translated at actual exchange rates in effect during the period, except for those items related to balance sheet amounts that are remeasured at historical exchange rates. Gains and losses from foreign currency remeasurement are included in earnings of the period. Gains and (losses) resulting from foreign currency transactions are included in "Cost of sales (exclusive of depreciation, amortization and depletion)." |
Asset impairments | Asset impairments— The Company evaluates long-term assets when events or changes in economic circumstances indicate that the carrying amount of such assets may not be recoverable. These evaluations are based on business plans that are prepared using a time horizon that is reflective of the Company's expectations of metal prices over its business cycle. The Company is currently using a long-term average copper price and an average molybdenum price for impairment tests, reflective of what the Company believes is the lower level of the current price environment. The results of its impairment tests using these long-term copper and molybdenum prices show no impairment in the carrying value of their assets. In recent years testing using assumptions for long-term average prices have resulted in stricter evaluation for impairment analysis than would the higher three year average prices for copper and molybdenum prices. Should this situation reverse in the future with three year average prices below the long-term price assumption, the Company would assess the need to use the three year average prices in its evaluations. The Company uses an estimate of the future undiscounted net cash flows of the related asset or asset group over the remaining life to measure whether the assets are recoverable and measures any impairment by reference to fair value. |
Other comprehensive income | Other comprehensive income— Comprehensive income represents changes in equity during a period, except those resulting from investments by owners and distributions to owners. During the fiscal years ended December 31, 2016, 2015 and 2014, the components of "other comprehensive income (loss)" were, the unrecognized gain (loss) on employee benefit obligations and unrealized gain (loss) on available-for-sale securities (which were not material in the aforementioned years). |
Business segments | Business segments— Company management views Southern Copper as having three reportable segments and manages it on the basis of these segments. The segments identified by the Company are: 1) the Peruvian operations, which include the two open-pit copper mines in Peru and the plants and services supporting such mines, 2) the Mexican open-pit copper mines, which include La Caridad and Buenavista mine complexes and their supporting facilities and 3) the Mexican underground mining operations, which include five underground mines that produce zinc, lead, copper, silver and gold, a coal mine and a zinc refinery. Please see Note 18 "Segments and Related Information." Senior management officers of the Company focus on operating income as measure of performance to evaluate different segments, and to make decisions to allocate resources to the reported segments. These are common measures in the mining industry. |
PROPOSED ACCOUNTING STANDARDS | PROPOSED ACCOUNTING STANDARDS In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers" (Topic 606). The objective of the new revenue standard is to provide a single comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries and across capital markets. The core principle of the standard is that the Company should recognize revenue to represent the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. The Company should apply the following five steps to achieve the core principle: Step 1: Identify the contract(s) with a customer. Step 2: Identify the performance obligations (promises) in the contract. Step 3: Determine the transaction price. Step 4: Allocate the transaction price to the performance obligations in the contract. Step 5: Recognize revenue when (or as) the Company satisfies a performance obligation. The guidance also specifies the accounting for some costs to obtain or fulfill a contract with a customer. Additionally, the Company should disclose sufficient qualitative and quantitative information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. On July 9, 2015, the FASB approved a one year deferral of the effective date of the new revenue standard for all entities. This revenue standard is effective for the first interim period within annual reporting periods beginning after December 15, 2017, and early adoption is not permitted. The Company is evaluating the impact of the adoption of this new standard on the consolidated financial information. |
