Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Use of Estimates | Use of Estimates The preparation of financial statements, in conformity with 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. The more significant areas requiring the use of management estimates and assumptions related to mineral reserves future realizable cash flow; environmental, reclamation and closure obligations; valuation of long-lived assets; valuation of inventory; valuation of post-employment, post-retirement and other employee benefit liabilities; valuation of tax assets; reserves for contingencies and litigation; the fair value of derivative instruments; and the fair value of loans to and accounts receivable from Canadian entities. Actual results could differ from estimates. On an ongoing basis, management reviews estimates. Changes in facts and circumstances may alter such estimates and affect the results of operations and financial position in future periods.
Basis Of Consolidation | Basis of Consolidation The consolidated financial statements include our accounts and the accounts of our wholly owned and majority-owned subsidiaries, including the following operations at December 31, 2016:
Name |  | Location |  | Ownership Interest |  | Operation |  | Status of Operations
Northshore |  | Minnesota |  | 100.0% |  | Iron Ore |  | Active
United Taconite |  | Minnesota |  | 100.0% |  | Iron Ore |  | Active
Tilden |  | Michigan |  | 85.0% |  | Iron Ore |  | Active
Empire |  | Michigan |  | 79.0% |  | Iron Ore |  | Indefinitely Idled
Koolyanobbing |  | Western Australia |  | 100.0% |  | Iron Ore |  | Active
Intercompany transactions and balances are eliminated upon consolidation.
Equity Method Investments | Equity Method Investments Investments in unconsolidated ventures that we have the ability to exercise significant influence over, but not control, are accounted for under the equity method. Hibbing Our 23% ownership interest in Hibbing is recorded as an equity method investment. As of December 31, 2016 and December 31, 2015, our investment in Hibbing was $8.7 million and $2.4 million, respectively, classified in Other liabilities in the Statements of Consolidated Financial Position. Our share of equity income (loss) is eliminated against consolidated product inventory upon production, and against Cost of goods sold and operating expenses when sold. This effectively reduces our cost for our share of the mining ventures' production cost, reflecting the cost-based nature of our participation in unconsolidated ventures.
Noncontrolling Interests [Policy Text Block] | Noncontrolling Interests Noncontrolling interest is primarily comprised of the 21% noncontrolling interest in the consolidated, but less-than-wholly-owned subsidiary at our Empire mining venture and through the CCAA filing on January 27, 2015, the 17.2% noncontrolling interest in the Bloom Lake operations. Financial results prior to the deconsolidation of the Bloom Lake Group and subsequent expenses directly associated with the Canadian Entities are included in our financial statements. The net loss and income attributable to the noncontrolling interest of the Empire mining venture was $25.2 million and $8.6 million for the years ended December 31, 2016 and December 31, 2015, respectively. There was no net income or loss attributable to the noncontrolling interest related to Bloom Lake for the year ended December 31, 2016. This compares with a net loss attributable to the noncontrolling interest related to Bloom Lake of $7.7 million for the year ended December 31, 2015. See NOTE 14 - DISCONTINUED OPERATIONS for further information.
Cash and Cash Equivalents | Cash Equivalents Cash and cash equivalents include cash on hand and on deposit as well as all short-term securities held for the primary purpose of general liquidity. We consider investments in highly liquid debt instruments with an original maturity of three months or less from the date of acquisition to be cash equivalents. We routinely monitor and evaluate counterparty credit risk related to the financial institutions by which our short-term investment securities are held.
Trade and Other Accounts Receivable | Trade Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We establish provisions for losses on accounts receivable when it is probable that all or part of the outstanding balance will not be collected. We regularly review our accounts receivable balances and establish or adjust the allowance as necessary using the specific identification method. The allowance for doubtful accounts was zero and $7.1 million at December 31, 2016 and 2015, respectively. There was no bad debt expense for the years ended December 31, 2016 and 2014. There was $7.1 million bad debt expense for the year ended December 31, 2015.
Inventory | Inventories U.S. Iron Ore U.S. Iron Ore product inventories are stated at the lower of cost or market. Cost of iron ore inventories is determined using the LIFO method. We had approximately 1.5 million long tons and 1.3 million long tons of finished goods stored at ports and customer facilities on the lower Great Lakes to service customers at December 31, 2016 and 2015, respectively. We maintain ownership of the inventories until title has transferred to the customer, usually when payment is received. Maintaining ownership of the iron ore products at ports on the lower Great Lakes reduces risk of non-payment by customers. Asia Pacific Iron Ore Asia Pacific Iron Ore product inventories are stated at the lower of cost or market. Costs of iron ore inventories are being valued on a weighted average cost basis. We maintain ownership of the inventories until title has transferred to the customer, which generally is when the product is loaded into the vessel.
Inventory Supplies | Supplies and Other Inventories Supply inventories include replacement parts, fuel, chemicals and other general supplies, which are expected to be used or consumed in normal operations. Supply inventories also include critical spares. Critical spares are replacement parts for equipment that is critical for the continued operation of the mine or processing facilities. Supply inventories are stated at the lower of cost or market using average cost, less an allowance for obsolete and surplus items. The allowance for obsolete and surplus items was $14.0 million and $31.8 million at December 31, 2016 and 2015, respectively.
Derivatives | Derivative Financial Instruments and Hedging Activities We are exposed to certain risks related to the ongoing operations of our business, including those caused by changes in commodity prices, interest rates and foreign currency exchange rates. We have established policies and procedures, including the use of certain derivative instruments, to manage such risks, if deemed necessary. Derivative financial instruments are recognized as either assets or liabilities in the Statements of Consolidated Financial Position and measured at fair value. For derivative instruments that have not been designated as cash flow hedges, changes in fair value are recorded in the period of the instrument's earnings or losses. Refer to NOTE 13 - DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES for further information.
Property, Plant and Equipment | Property, Plant and Equipment Our properties are stated at the lower of cost less accumulated depreciation or fair value. Depreciation of plant and equipment is computed principally by the straight-line method based on estimated useful lives, not to exceed the mine lives. The U.S. Iron Ore operations use the double-declining balance method of depreciation for certain mining equipment. The Asia Pacific Iron Ore operation uses the production output method for certain mining equipment. Depreciation is provided over the following estimated useful lives:
Asset Class |  | Basis |  | Life
Office and information technology |  | Straight line |  | 3 to 15 Years
Buildings |  | Straight line |  | 45 Years
Mining equipment |  | Straight line/Double declining balance |  | 3 to 20 Years
Processing equipment |  | Straight line |  | 10 to 45 Years
Electric power facilities |  | Straight line |  | 10 to 45 years
Land improvements |  | Straight line |  | 20 to 45 years
Asset retirement obligation |  | Straight line |  | Life of mine
Depreciation continues to be recognized when operations are idled temporarily. Refer to NOTE 4 - PROPERTY, PLANT AND EQUIPMENT for further information.
Capitalized Stripping Costs | Capitalized Stripping Costs During the development phase, stripping costs are capitalized as a part of the depreciable cost of building, developing and constructing a mine. These capitalized costs are amortized over the productive life of the mine using the units of production method. The production phase does not commence until the removal of more than a de minimis amount of saleable mineral material occurs in conjunction with the removal of overburden or waste material for purposes of obtaining access to an ore body. The stripping costs incurred in the production phase of a mine are variable production costs included in the costs of the inventory produced (extracted) during the period that the stripping costs are incurred. Stripping costs related to expansion of a mining asset of proven and probable reserves are variable production costs that are included in the costs of the inventory produced during the period that the stripping costs are incurred.
Other Intangible Assets and Liabilities | Other Intangible Assets and Liabilities Other intangible assets are subject to periodic amortization on a straight-line basis over their estimated useful lives as follows:
Intangible Assets |  | Basis |  | Useful Life (years)
Permits - Asia Pacific Iron Ore |  | Units of production |  | Life of mine
Permits - USIO |  | Straight line |  | Life of mine
Impairment or Disposal of Long-Lived Assets | Asset Impairment Long-Lived Tangible and Intangible Assets We monitor conditions that may affect the carrying value of our long-lived tangible and intangible assets when events and circumstances indicate that the carrying value of the asset groups may not be recoverable. In order to determine if assets have been impaired, assets are grouped and tested at the lowest level for which identifiable, independent cash flows are available ("asset group"). An impairment loss exists when projected undiscounted cash flows are less than the carrying value of the asset group. The measurement of the impairment loss to be recognized is based on the difference between the fair value and the carrying value of the asset group. Fair value can be determined using a market approach, income approach or cost approach. During the year ended December 31, 2016, there were no impairment indicators present; as a result no impairment assessments were required. As a result of the 2015 assessments, there were no material impairment charges related to long-lived tangible or intangible assets at our continuing operations. During 2014, we recorded a long-lived tangible asset impairment charge of $537.8 million and an intangible asset impairment charge of $13.8 million in our Statements of Consolidated Operations related to our continuing operations. Refer to NOTE 4 - PROPERTY, PLANT AND EQUIPMENT, NOTE 12 - GOODWILL AND OTHER INTANGIBLE ASSETS AND LIABILITIES and NOTE 6 - FAIR VALUE OF FINANCIAL INSTRUMENTS for further information.
Fair Value of Financial Instruments | Fair Value Measurements Valuation Hierarchy ASC 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for classification of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Inputs refer broadly to the assumptions that market participants would use in pricing an asset or liability. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our own views about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized below:
• | Level 1 — Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets.
• | Level 2 — Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
• | Level 3 — Valuation is based upon other unobservable inputs that are significant to the fair value measurement.
The classification of assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement in its entirety. Valuation methodologies used for assets and liabilities measured at fair value are as follows: Cash Equivalents Where quoted prices are available in an active market, cash equivalents are classified within Level 1 of the valuation hierarchy. Cash equivalents classified in Level 1 at December 31, 2016 and 2015 include money market funds. Valuation of these instruments is determined using a market approach and is based upon unadjusted quoted prices for identical assets in active markets. Derivative Financial Instruments Derivative financial instruments valued using financial models that use as their basis readily observable market parameters are classified within Level 2 of the valuation hierarchy. Such derivative financial instruments include our commodity hedge and foreign currency exchange contracts. Derivative financial instruments that are valued based upon models with significant unobservable market parameters and are normally traded less actively, are classified within Level 3 of the valuation hierarchy. Refer to NOTE 6 - FAIR VALUE OF FINANCIAL INSTRUMENTS and NOTE 7 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further information.
Pension and Other Postretirement Plans | Pensions and Other Postretirement Benefits We offer defined benefit pension plans, defined contribution pension plans and other postretirement benefit plans, primarily consisting of retiree healthcare benefits, to most employees in North America as part of a total compensation and benefits program. We do not have employee pension or post-retirement benefit obligations at our Asia Pacific Iron Ore operations. We recognize the funded or unfunded status of our postretirement benefit obligations on our December 31, 2016 and 2015 Statements of Consolidated Financial Position based on the difference between the market value of plan assets and the actuarial present value of our retirement obligations on that date, on a plan-by-plan basis. If the plan assets exceed the retirement obligations, the amount of the surplus is recorded as an asset; if the retirement obligations exceed the plan assets, the amount of the underfunded obligations are recorded as a liability. Year-end balance sheet adjustments to postretirement assets and obligations are recorded as Accumulated other comprehensive loss. The actuarial estimates of the PBO and APBO incorporate various assumptions including the discount rates, the rates of increases in compensation, healthcare cost trend rates, mortality, retirement timing and employee turnover. The discount rate is determined based on the prevailing year-end rates for high-grade corporate bonds with a duration matching the expected cash flow timing of the benefit payments from the various plans. The remaining assumptions are based on our estimates of future events by incorporating historical trends and future expectations. The amount of net periodic cost that is recorded in the Statements of Consolidated Operations consists of several components including service cost, interest cost, expected return on plan assets, and amortization of previously unrecognized amounts. Service cost represents the value of the benefits earned in the current year by the participants. Interest cost represents the cost associated with the passage of time. Certain items, such as plan amendments, gains and/or losses resulting from differences between actual and assumed results for demographic and economic factors affecting the obligations and assets of the plans, and changes in other assumptions are subject to deferred recognition for income and expense purposes. The expected return on plan assets is determined utilizing the weighted average of expected returns for plan asset investments in various asset categories based on historical performance, adjusted for current trends. See NOTE 7 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further information.
Asset Retirement Obligations | Asset Retirement Obligations Asset retirement obligations are recognized when incurred and recorded as liabilities at fair value. The fair value of the liability is determined as the discounted value of the expected future cash flow. The asset retirement obligation is accreted over time through periodic charges to earnings. In addition, the asset retirement cost is capitalized and amortized over the life of the related asset. Reclamation costs are adjusted periodically to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. We review, on an annual basis, unless otherwise deemed necessary, the asset retirement obligation at each mine site in accordance with the provisions of ASC 410, Asset Retirement and Environmental Obligations. We perform an in-depth evaluation of the liability every three years in addition to routine annual assessments. Future reclamation costs for inactive mines are accrued based on management’s best estimate at the end of each period of the costs expected to be incurred at a site. Such cost estimates include, where applicable, ongoing maintenance and monitoring costs. Changes in estimates at inactive mines are reflected in earnings in the period an estimate is revised. See NOTE 11 - ENVIRONMENTAL AND MINE CLOSURE OBLIGATIONS for further information.
Environmental Costs | Environmental Remediation Costs We have a formal policy for environmental protection and restoration. Our mining and exploration activities are subject to various laws and regulations governing protection of the environment. We conduct our operations to protect the public health and environment and believe our operations are in compliance with applicable laws and regulations in all material respects. Our environmental liabilities, including obligations for known environmental remediation exposures at active and closed mining operations and other sites, have been recognized based on the estimated cost of investigation and remediation at each site. If the cost only can be estimated as a range of possible amounts with no point in the range being more likely, the minimum of the range is accrued. Future expenditures are not discounted unless the amount and timing of the cash disbursements reasonably can be estimated. It is possible that additional environmental obligations could be incurred, the extent of which cannot be assessed. Potential insurance recoveries have not been reflected in the determination of the liabilities. See NOTE 11 - ENVIRONMENTAL AND MINE CLOSURE OBLIGATIONS for further information.
Revenue Recognition | Revenue Recognition We sell our products pursuant to comprehensive supply agreements negotiated and executed with our customers. Revenue is recognized from a sale when persuasive evidence of an arrangement exists, the price is fixed or determinable, the product is delivered in accordance with F.O.B. terms, title and risk of loss have transferred to the customer in accordance with the specified provisions of each supply agreement and collection of the sales price reasonably is assured. Our U.S. Iron Ore and Asia Pacific Iron Ore supply agreements provide that title and risk of loss transfer to the customer either upon loading of the vessel, shipment or, as is the case with some of our U.S. Iron Ore supply agreements, when payment is received. Under certain term supply agreements, we ship the product to ports on the lower Great Lakes or to the customers’ facilities prior to the transfer of title. Our rationale for shipping iron ore products to certain customers and retaining title until payment is received for these products is to minimize credit risk exposure. Sales are recorded at a sales price specified in the relevant supply agreements resulting in revenue and a receivable at the time of sale. Upon revenue recognition for provisionally priced sales, a freestanding derivative is created for the difference between the sales price used and expected future settlement price. The derivative, which does not qualify for hedge accounting, is adjusted to fair value through Product revenues as a revenue adjustment each reporting period based upon current market data and forward-looking estimates determined by management until the final sales price is determined. The principal risks associated with recognition of sales on a provisional basis include iron ore price fluctuations between the date initially recorded and the date of final settlement. For revenue recognition, we estimate the future settlement rate; however, if significant changes in iron ore prices occur between the provisional pricing date and the final settlement date, we might be required to either return a portion of the sales proceeds received or bill for the additional sales proceeds due based on the provisional sales price. Refer to NOTE 13 - DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES for further information. In addition, certain supply agreements with one customer include provisions for supplemental revenue or refunds based on the customer’s annual steel pricing for the year the product is consumed in the customer’s blast furnaces. We account for this provision as a free standing derivative instrument at the time of sale and record this provision at fair value until the year the product is consumed and the amounts are settled as an adjustment to revenue. Refer to NOTE 13 - DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES for further information. Revenue from product sales and services also includes reimbursement for freight charges associated with domestic freight and venture partner cost reimbursements for the U.S. Iron Ore operations and freight associated with CFR based shipments paid on behalf of customers for the Asia Pacific Iron Ore operations. These are included in Freight and venture partners' cost reimbursements separate from Product revenues. Revenue is recognized for the expected reimbursement of services when the services are performed.
Revenue Recognition, Deferred Revenue | Deferred Revenue The terms of one of our U.S. Iron Ore pellet supply agreements required supplemental payments to be paid by the customer during the period 2009 through 2012, with the option to defer a portion of the 2009 monthly amount in exchange for interest payments until the deferred amount was repaid in 2013. Installment amounts received under this arrangement in excess of sales were classified as deferred revenue in the Statements of Consolidated Financial Position upon receipt of payment. Revenue is recognized over the life of the supply agreement, which extends until 2022, in equal annual installments. As of December 31, 2016 and 2015, installment amounts received in excess of sales totaled $77.1 million and $89.9 million, respectively. As of December 31, 2016, deferred revenue of $16.4 million was recorded in Other current liabilities and $64.2 million was recorded as long-term in Other liabilities in the Statements of Consolidated Financial Position. As of December 31, 2015, deferred revenue of $12.8 million was recorded in Other current liabilities and $77.1 million was recorded as long-term in Other liabilities in the Statements of Consolidated Financial Position. In 2016 and 2014, due to the payment terms and the timing of cash receipts near year-end, cash receipts exceeded shipments for certain customers. The shipments were completed early in the subsequent years. We considered whether revenue should be recognized on these sales under the “bill and hold” guidance provided by the SEC Staff; however, based upon the assessment performed, revenue recognition on these transactions totaling $3.4 million and $29.3 million were deferred on the Statements of Consolidated Financial Position for the years ended December 31, 2016 and 2014, respectively.
Cost of Sales | Cost of Goods Sold Cost of goods sold and operating expenses represents all direct and indirect costs and expenses applicable to the sales of our mining operations. Operating expenses primarily represent the portion of the Tilden mining venture costs for which we do not own; that is, the costs attributable to the share of the mine’s production owned by the other joint venture partner in the Tilden mine. The mining venture functions as a captive cost company; it supplies product only to its owners effectively for the cost of production. Accordingly, the noncontrolling interests’ revenue amounts are stated at cost of production and are offset by an equal amount included in Cost of goods sold and operating expenses resulting in no sales margin reflected for the noncontrolling partner participant. As we are responsible for product fulfillment, we act as a principal in the transaction and, accordingly, record revenue under these arrangements on a gross basis. The following table is a summary of reimbursements in our U.S. Iron Ore operations for the years ended December 31, 2016, 2015 and 2014:
|  | (In Millions)
|  | Year Ended December 31,
|  | 2016 |  | 2015 |  | 2014
Reimbursements for: |  |  |  |  |  |
Freight |  | $ | 106.8 |  |  | $ | 105.3 |  |  | $ | 163.0 |
Venture partners’ cost |  | 68.0 |  |  | 52.0 |  |  | 108.0 |
Total reimbursements |  | $ | 174.8 |  |  | $ | 157.3 |  |  | $ | 271.0 |
In 2014, we began selling a portion of our Asia Pacific Iron Ore product on a CFR basis. As a result, $20.7 million, $23.6 million and $6.9 million of freight was included in Cost of goods sold and operating expenses for the years ended December 31, 2016, 2015 and 2014, respectively. Where we have joint ownership of a mine, our contracts entitle us to receive royalties and/or management fees, which we earn as the pellets are produced.
Repairs And Maintenance | Repairs and Maintenance Repairs, maintenance and replacement of components are expensed as incurred. The cost of major equipment overhauls is capitalized and depreciated over the estimated useful life, which is the period until the next scheduled overhaul, generally five years. All other planned and unplanned repairs and maintenance costs are expensed when incurred.
Share-based Compensation, Option and Incentive Plans | Share-Based Compensation The fair value of each performance share grant is estimated on the date of grant using a Monte Carlo simulation to forecast relative TSR performance. Consistent with the guidelines of ASC 718, Stock Compensation, a correlation matrix of historic and projected stock prices was developed for both the Company and its predetermined peer group of mining and metals companies. The fair value assumes that performance goals will be achieved. The expected term of the grant represents the time from the grant date to the end of the service period for each of the three plan-year agreements. We estimated the volatility of our common shares and that of the peer group of mining and metals companies using daily price intervals for all companies. The risk-free interest rate is the rate at the grant date on zero-coupon government bonds, with a term commensurate with the remaining life of the performance plans. The fair value of stock options is estimated on the date of grant using a Black-Scholes model using the grant date price of our common shares and option exercise price, and assumptions regarding the option’s expected term, the volatility of our common shares, the risk-free interest rate, and the dividend yield over the option’s expected term. Upon vesting of share-based compensation awards, we issue shares from treasury shares before issuing new shares. Refer to NOTE 8 - STOCK COMPENSATION PLANS for additional information.
Income Tax | Income Taxes Income taxes are based on income for financial reporting purposes, calculated using tax rates by jurisdiction, and reflect a current tax liability or asset for the estimated taxes payable or recoverable on the current year tax return and expected annual changes in deferred taxes. Any interest or penalties on income tax are recognized as a component of income tax expense. We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial results of operations. Accounting for uncertainty in income taxes recognized in the financial statements requires that a tax benefit from an uncertain tax position be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on technical merits. See NOTE 9 - INCOME TAXES for further information.
Discontinued Operations | Discontinued Operations In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for reporting discontinued operations and requires additional disclosures about discontinued operations. The standard requires that an entity report as a discontinued operation only a disposal that represents a strategic shift in operations that has a major effect on its operations and financial results. ASU 2014-08 is effective prospectively for new disposals that occur within annual periods beginning on or after December 15, 2014. Early adoption was permitted and we adopted ASU 2014-08 during the year ended December 31, 2014. North American Coal Operations As we executed our strategy to focus on strengthening our U.S. Iron Ore operations, management determined as of March 31, 2015 that our North American Coal operating segment met the criteria to be classified as held for sale under ASC 205, Presentation of Financial Statements and continued to meet the criteria throughout 2015. In December 2015, we completed the sale of our remaining two metallurgical coal operations, Oak Grove and Pinnacle mines, which marked our exit from the coal business. Our plan to sell the Oak Grove and Pinnacle mine assets represented a strategic shift in our business. For this reason, our previously reported North American Coal operating segment results for all periods, prior to the March 31, 2015 held for sale determination, as well as costs to exit are classified as discontinued operations. Refer to NOTE 14 - DISCONTINUED OPERATIONS for further discussion of our discontinued operations. Canadian Operations As more fully described in NOTE 14 - DISCONTINUED OPERATIONS, in January 2015, we announced that the Bloom Lake Group commenced restructuring proceedings in Montreal, Quebec under the CCAA. At that time, we had suspended Bloom Lake operations and for several months had been exploring options to sell certain of our Canadian assets, among other initiatives. Effective January 27, 2015, following the CCAA filing of the Bloom Lake Group, we deconsolidated the Bloom Lake Group and certain other wholly-owned subsidiaries comprising substantially all of our Canadian operations. Additionally, on May 20, 2015, the Wabush Group commenced restructuring proceedings in Montreal, Quebec under the CCAA which resulted in the deconsolidation of the remaining Wabush Group entities that were not previously deconsolidated. The Wabush Group was no longer generating revenues and was not able to meet its obligations as they came due. As a result of this action, the CCAA protections granted to the Bloom Lake Group were extended to include the Wabush Group to facilitate the reorganization of each of their businesses and operations. Our Canadian exit represents a strategic shift in our business. For this reason, our previously reported Eastern Canadian Iron Ore and Ferroalloys operating segment results for all periods prior to the respective deconsolidations as well as costs to exit are classified as discontinued operations.
Foreign Currency Transactions and Translations | Foreign Currency Our financial statements are prepared with the U.S. dollar as the reporting currency. The functional currency of our Australian subsidiaries is the Australian dollar. The functional currency of all other international subsidiaries is the U.S. dollar. The financial statements of international subsidiaries are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and a weighted average exchange rate for each period for revenues, expenses, gains and losses. Where the local currency is the functional currency, translation adjustments are recorded as Accumulated other comprehensive loss. Income taxes generally are not provided for foreign currency translation adjustments. To the extent that monetary assets and liabilities, inclusive of short-term and certain long-term intercompany loans, are recorded in a currency other than the functional currency, these amounts are remeasured each reporting period, with the resulting gain or loss being recorded in the Statements of Consolidated Operations. Transaction gains and losses resulting from remeasurement of intercompany loans are included in Miscellaneous - net in our Statements of Consolidated Operations. The following represents the net gain related to impact of transaction gains and losses resulting from remeasurement for the years ended December 31, 2016, 2015 and 2014:
|  | (In Millions)
|  | 2016 |  | 2015 |  | 2014
Remeasurement of intercompany loans |  | $ | (16.6 | ) |  | $ | 11.5 |  |  | $ | 19.7 |
Remeasurement of cash and cash equivalents |  | (1.0 | ) |  | 1.5 |  |  | 10.6 |
Other remeasurement |  | 0.8 |  |  | 3.3 |  |  | (1.3 | )
Net gain (loss) related to impact of transaction gains and losses resulting from remeasurement |  | (16.8 | ) |  | 16.3 |  |  | 29.0 |
Earnings Per Share | Earnings Per Share We present both basic and diluted earnings per share amounts for continuing operations and discontinued operations. Basic earnings per share amounts are calculated by dividing Net Income (Loss) from Continuing Operations Attributable to Cliffs Shareholders less any paid or declared but unpaid dividends on our depositary shares by the weighted average number of common shares outstanding during the period presented. Diluted earnings per share amounts are calculated by dividing Net Income (Loss) from Continuing Operations Attributable to Cliffs Shareholders by the weighted average number of common shares, common share equivalents under stock plans using the treasury stock method and the number of common shares that would be issued under an assumed conversion of our outstanding depositary shares, each representing a 1/40th interest in a share of our Series A Mandatory Convertible Preferred Stock, Class A, under the if-converted method. We currently do not have any outstanding depositary shares. Historically, when we have had outstanding depositary shares, they were convertible into common shares based on the volume weighted average of closing prices of our common shares over the 20 consecutive trading day period ending on the third day immediately preceding the end of that reporting period. Common share equivalents are excluded from EPS computations in the periods in which they have an anti-dilutive effect. See NOTE 19 - EARNINGS PER SHARE for further information.
Recent Accounting Pronouncements | Recent Accounting Pronouncements Issued and Adopted In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payment s. The new standard addresses eight specific changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. The guidance is effective for interim and annual reporting periods beginning after December 15, 2017, and early adoption is permitted. We have adopted the guidance for the period ended December 31, 2016 and have applied this amended accounting guidance to the Statements of Consolidated Cash Flows for all periods presented. The adoption of ASU 2016-15 did not have an impact on prior results reported in the Statements of Consolidated Cash Flows. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties About an Entity's Ability to Continue as a Going Concern. ASU 2014-15 explicitly requires management to assess an entity's ability to continue as a going concern, and to provide related footnote disclosure in certain circumstances. ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Specifically, ASU 2014-15 provides a definition of the term "substantial doubt" and requires an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). It also requires certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans and requires an express statement and other disclosures when substantial doubt is not alleviated. The new standard is effective for all entities in the first annual period ending after December 15, 2016 and for annual periods and interim periods thereafter. We have adopted the guidance for the year ended December 31, 2016. The adoption of ASU 2014-15 did not impact our disclosures in 2016. In October 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes. This update simplifies the presentation of deferred income taxes, by requiring that deferred tax liabilities and assets be classified as non-current in a classified statement of financial position. This update is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods; however, early adoption was permitted. This guidance can also be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. We adopted the guidance during the year ended December 31, 2015 and have applied this amended accounting guidance to our deferred tax liabilities and assets for all periods presented. The adoption of ASU 2015-17 did not have an impact on our Statements of Consolidated Operations or Statements of Consolidated Cash Flows. The impact of the adoption of the guidance resulted in any current deferred tax assets or liabilities being reclassified to non-current deferred tax assets or liabilities on the Statements of Consolidated Financial Position. Issued and Not Effective In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases. For lessees, leases will continue to be classified as either operating or finance leases in the income statement. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model. The effective date of the new standard for public companies is for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented. We are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, R e venues from Contracts with Customers. The new revenue guidance broadly replaces the revenue guidance provided throughout the Codification. The core principle of the revenue guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The new revenue guidance also requires the capitalization of certain contract acquisition costs. Reporting entities must prepare new disclosures providing qualitative and quantitative information on the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. New disclosures also include qualitative and quantitative information on significant judgments, changes in judgments, and contract acquisition assets. At issuance, ASU 2014-09 was effective starting in 2017 for calendar-year public entities, and interim periods within that year. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which defers the adoption of ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. During the fourth quarter of 2016, we completed the initial evaluation of the new standard and the related assessment and review of a representative sample of existing revenue contracts with our customers. We determined, on a preliminary basis, that although the timing and pattern of revenue recognition may change, the amount of revenue recognized during the year should remain substantially the same. We anticipate utilizing the full retrospective transition method. The primary impact of the adoption on our consolidated financial statements will be the additional required disclosures around revenue recognition in the notes to the consolidated financial statements.
