Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	NOTE 1—BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Nature of Operations McDermott International, Inc. (“MDR”), a corporation incorporated under the laws of the Republic of Panama in 1959, is a leading provider of integrated engineering, procurement, construction and installation (“EPCI”) and module fabrication services for upstream field developments worldwide. We deliver fixed and floating production facilities, pipeline installations and subsea systems from concept to commissioning for complex offshore and subsea oil and gas projects. Operating in approximately 20 countries across Americas, Europe, Africa, the Middle East, Asia and Australia, our integrated resources include a diversified fleet of marine vessels, fabrication facilities and engineering offices. We support our activities with comprehensive project management and procurement services, while utilizing our fully integrated capabilities in both shallow water and deepwater construction. Our customers include national, major integrated and other oil and gas companies, and we operate in most major offshore oil and gas producing regions throughout the world. We execute our contracts through a variety of methods, principally fixed-price, but also including cost reimbursable, cost-plus, day-rate and unit-rate basis or some combination of those methods. In these Notes to our Consolidated Financial Statements, unless the context otherwise indicates, “we,” “us” and “our” mean MDR and its consolidated subsidiaries. Basis of Presentation The accompanying Consolidated Financial Statements are unaudited and have been prepared from our books and records in accordance with Rule 10-1 of Regulation S-X for interim financial information. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements. In the opinion of our management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation have been included. The results of operations for interim periods are not necessarily indicative of results of operations for a full year. These Consolidated Financial Statements should be read in conjunction with our Consolidated Financial Statements and Notes thereto included in MDR’s Annual Report on Form 10-K for the year ended December 31, 2015 filed with the SEC on February 22, 2016. Classification Certain prior year amounts have been reclassified for consistency with the current year presentation. Our Consolidated Financial Statements previously reported income and loss from investment in unconsolidated affiliates as components of operating income. In the first quarter of 2016, we concluded that classification of loss from investments in unconsolidated affiliates after provision for income tax better reflected how the operations of our unconsolidated affiliates relate to our business as a whole. Recently Issued and Adopted Accounting Guidance Stock Compensation—In March 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-09, Compensation—Stock Compensation (Topic 718): Improvement to Employee Share-Based Payment Accounting. This ASU simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, earnings per share and classification in the statement of cash flows. We adopted this ASU in the second quarter of 2016. Our adoption did not have a material impact on the presentation of our Consolidated Financial Statements. Income Tax—In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. Under this ASU an entity shall classify deferred tax assets and liabilities as noncurrent. We adopted ASU 2015-17 in the first quarter of 2016. Our adoption of that ASU did not have a material impact on the presentation of our Consolidated Financial Statements. All comparable periods presented have been revised to reflect this change. Consolidation—In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This ASU eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, an acquirer will recognize a measurement-period adjustment during the period in which it determines the amount of the adjustment. In February 2015, the FASB issued ASU 2015-02, Consolidation: Amendments to the Consolidation Analysis, which amends and changes the consolidation analysis currently required under U.S. GAAP. This ASU modifies the process used to evaluate whether limited partnerships and similar entities are variable interest entities or voting interest entities; affects the analysis performed by reporting entities regarding variable interest entities, particularly those with fee arrangements and related party relationships; and provides a scope exception for certain investment funds. The amendments in ASUs 2015-16 and 2015-02 are effective for annual and interim periods beginning after December 15, 2015. Early adoption was permitted. We adopted these ASUs in the first quarter of 2016. Our adoption of these ASUs did not have a material impact on the accompanying Consolidated Financial Statements. Accounting Guidance Issued But Not Adopted as of June 30, 2016 Financial Instruments—In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU will require a financial asset measured at amortized cost basis to be presented at the net amount expected to be collected. A valuation account, allowance for credit losses, will be deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. This ASU is effective for interim and annual periods beginning after December 15, 2019. We are currently assessing the impact of this guidance on our future Consolidated Financial Statements and related disclosures. Derivatives—In March 2016, the FASB issued ASU 2016-06, Derivatives and hedging (Topic 815): Contingent Put and Call Options in Debt Instruments. This ASU clarifies that a contingent put or call option embedded in a debt instrument would be evaluated for possible separate accounting as a derivative instrument without regard to the nature of the exercise contingency. This ASU is effective for interim and annual periods beginning after December 15, 2016. Early adoption is permitted. We are currently assessing the impact of this guidance on our future Consolidated Financial Statements and related disclosures. In March 2016, the FASB issued ASU 2016-05, Derivatives and hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships. The amendments in this ASU clarify that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument under Topic 815 does not require de-designation of that hedging relationship, provided that all other hedge accounting criteria continue to be met. This ASU is effective for interim and annual periods beginning after December 15, 2016. Early adoption is permitted. The application of this ASU is not expected to have a material impact on our Consolidated Financial Statements. Leases—In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The ASU will require entities that lease assets—referred to as “lessees”—to recognize on the balance sheet the assets and liabilities for the rights and obligations created by leases with lease terms of more than 12 months. Consistent with current U.S. GAAP, the recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current U.S. GAAP—which requires only capital leases to be recognized on the balance sheet—the new ASU will require both types of leases to be recognized on the balance sheet. This ASU is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. We are currently assessing the impact of this ASU on our future Consolidated Financial Statements and related disclosures. Financial Assets and Liabilities—In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. Under this new guidance, entities will be required to measure all investments in equity securities that are not subject to equity method or consolidation accounting at fair value, with changes recognized in net income. Fair value changes related to instrument-specific credit risk in financial liabilities accounted for under the fair value option in Accounting Standards Codification 825 must be recorded in other comprehensive income instead of earnings. ASU 2016-01 also changes presentation and disclosure requirements for financial assets and liabilities. ASU 2016-01 is effective for interim and annual periods beginning after December 15, 2017, with early adoption not permitted except related to changes in fair value for financial liabilities. We are currently assessing the impact of these amendments on our future Consolidated Financial Statements and related disclosures. Going Concern—In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. Currently, there is no guidance in effect under U.S. GAAP regarding management’s responsibility to assess whether there is substantial doubt about an entity’s ability to continue as a going concern. Under ASU 2014-15, we will be required to assess our ability to continue as a going concern each interim and annual reporting period and provide certain disclosures if there is substantial doubt about our ability to continue as a going concern, including management’s plan to alleviate the substantial doubt. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods thereafter with early adoption permitted. We are currently assessing the impact of ASU 2014-15 on our future Consolidated Financial Statements and related disclosures. Revenue—In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. It also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the effective date of ASU 2014-09 to annual periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting revenue Gross versus Net), which improves the operability and understandability of the Topic 606 implementation guidance on principal versus agent considerations. Effective date and transition requirements for this ASU are the same as effective date and transition requirements for ASU 2014-09. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which provides clarifying guidance for identifying performance obligations and the licensing implementation guidance. The effective date and transition requirements for this ASU are the same as the effective date and transition requirements for ASU 2014-09. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides clarifying guidance in a few narrow areas and adds some practical expedients to the guidance. The effective date and transition requirements for this ASU are the same as the effective date and transition requirements for ASU 2014-09. We are currently evaluating the requirements of these ASUs and have not yet determined their impacts on our future Consolidated Financial Statements and related disclosures.
