Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Note 1 — Organization and Basis of Presentation Noble Corporation plc, a public limited company incorporated under the laws of England and Wales (“Noble-UK”), is a leading offshore drilling contractor for the oil and gas industry. We perform contract drilling services with our global fleet of mobile offshore drilling units. As of the filing date of this Quarterly Report on Form 10-Q, our fleet consisted of 15 jackups, nine drillships and eight semisubmersibles, including one high-specification, harsh environment jackup under construction. We report our contract drilling operations as a single reportable segment, Contract Drilling Services, which reflects how we manage our business, and the fact that all of our drilling fleet is dependent upon the worldwide oil and gas industry. The mobile offshore drilling units comprising our offshore rig fleet operate in a global market for contract drilling services and are often redeployed to different regions due to changing demands of our customers, which consist largely of major independent and government owned/controlled oil and gas companies throughout the world. As of June 30, 2015, our contract drilling services segment conducts operations in the United States, Brazil, Argentina, the North Sea, the Mediterranean Sea, the Black Sea, the Middle East, Asia and Australia. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921. Noble Corporation, a Cayman Islands company (“Noble-Cayman”), is an indirect, wholly-owned subsidiary of Noble-UK, our publicly-traded parent company. Noble-UK’s principal asset is all of the shares of Noble-Cayman. Noble-Cayman has no public equity outstanding. The consolidated financial statements of Noble-UK include the accounts of Noble-Cayman, and Noble-UK conducts substantially all of its business through Noble-Cayman and its subsidiaries. The accompanying unaudited consolidated financial statements of Noble-UK and Noble-Cayman have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) as they pertain to Quarterly Reports on Form 10-Q. Accordingly, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The unaudited financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the financial position and results of operations for the interim periods, on a basis consistent with the annual audited consolidated financial statements. All such adjustments are of a recurring nature. The December 31, 2014 Consolidated Balance Sheets presented herein are derived from the December 31, 2014 audited consolidated financial statements. These interim financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2014, filed by both Noble-UK and Noble-Cayman. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. Certain amounts in prior periods have been reclassified to conform to the current year presentation.

Spin-off of Paragon Offshore plc ("Paragon Offshore")	Note 2 – Spin-off of Paragon Offshore plc (“Paragon Offshore”) On August 1, 2014, Noble-UK completed the separation and spin-off of a majority of its standard specification offshore drilling business (the “Spin-off”) through a pro rata distribution of all of the ordinary shares of its wholly-owned subsidiary, Paragon Offshore, to the holders of Noble’s ordinary shares. Our shareholders received one share of Paragon Offshore for every three shares of Noble owned as of July 23, 2014, the record date for the distribution. Through the Spin-off, we disposed of most of our standard specification drilling units and related assets, liabilities and business. Prior to the Spin-off, Paragon Offshore issued approximately $1.7 billion of long-term debt. We used the proceeds from this debt to repay certain amounts outstanding under our commercial paper program. Prior to the completion of the Spin-off, Noble and Paragon Offshore entered into a series of agreements to effect the separation and Spin-off and govern the relationship between the parties after the Spin-off. Master Separation Agreement (“MSA”) The general terms and conditions relating to the separation and Spin-off are set forth in the MSA. The MSA identifies the assets transferred, liabilities assumed and contracts assigned either to Paragon Offshore by us or by Paragon Offshore to us in the separation and describes when and how these transfers, assumptions and assignments would occur. The MSA provides for, among other things, Paragon Offshore’s responsibility for liabilities relating to its business and the responsibility of Noble for liabilities related to our, and in certain limited cases, Paragon Offshore’s business, in each case irrespective of when the liability arose. The MSA also contains indemnification obligations and ongoing commitments by us and Paragon Offshore. Employee Matters Agreement (“EMA”) The EMA allocates liabilities and responsibilities between us and Paragon Offshore relating to employment, compensation and benefits and other employment related matters. Tax Sharing Agreement (“TSA”) The TSA provides for the allocation of tax liabilities and benefits between us and Paragon Offshore and governs the parties’ assistance with tax-related claims. Transition Services Agreements Under two transition services agreements, we agreed to continue, for a limited period of time, to provide various interim support services to Paragon Offshore, and Paragon Offshore agreed to provide various interim support services to us, including providing operational and administrative support for our remaining Brazilian operations.

For the three months ended June 30, 2015 and 2014, approximately 2 million and 1 million shares underlying stock options, respectively, were excluded from the diluted earnings per share as such stock options were not dilutive. Share capital As of June 30, 2015, Noble-UK had approximately 242.0 million shares outstanding and trading as compared to approximately 247.5 million shares outstanding and trading at December 31, 2014. The decrease in shares outstanding is primarily related to the repurchase of 6.2 million shares pursuant to our approved share repurchase program, discussed below. Our Board of Directors may increase our share capital through the issuance of up to 53 million authorized shares (at current nominal value of $0.01 per share) without obtaining shareholder approval. Our most recent quarterly dividend payment to shareholders, totaling approximately $93 million (or $0.375 per share), was declared on April 24, 2015 and paid on May 14, 2015 to holders of record on May 4, 2015. Share repurchases Under UK law, the company is only permitted to purchase its own shares by way of an “off-market purchase” in a plan approved by shareholders. In December 2014, we received shareholder approval to repurchase up to 37,000,000 ordinary shares, or approximately 15 percent of our outstanding ordinary shares at the time of the shareholder approval. Any repurchases are expected to be funded using cash on hand, cash from operations or short-term borrowings under our Credit Facilities. The authority to make such repurchases will expire on the later of April 2016 or the end of the Company’s 2016 annual general meeting of shareholders, at which time we could seek shareholder approval for further repurchases. During the six months ended June 30, 2015, we repurchased 6.2 million of our ordinary shares covered by this authorization for a total cost of approximately $101 million. During the three months ended June 30, 2015, we did not repurchase any of our shares.

We have a commercial paper program that allows us to issue up to $2.4 billion in unsecured commercial paper notes. Amounts issued under the commercial paper program are supported by the unused capacity under our Credit Facilities and, therefore, are classified as long-term on our Consolidated Balance Sheet. The outstanding amounts of commercial paper reduce availability under our Credit Facilities. The $2.4 billion facility provides us with the ability to issue up to $500 million in letters of credit. The issuance of letters of credit under the facility reduces the amount available for borrowing. At June 30, 2015, we had no letters of credit issued under the facility. Senior Unsecured Notes In March 2015, our indirect wholly-owned subsidiary, Noble Holding International Limited (“NHIL”), issued $1.1 billion aggregate principal amount of senior notes in three separate tranches, comprised of $250 million of 4.00% Senior Notes due 2018, $450 million of 5.95% Senior Notes due 2025, and $400 million of 6.95% Senior Notes due 2045. The weighted average coupon of all three tranches is 5.87%. The interest rate on these senior notes may be increased if the credit rating applicable to the notes is downgraded below certain specified levels. The net proceeds of approximately $1.08 billion, after expenses, were used to repay indebtedness outstanding under our Credit Facilities and commercial paper program. On August 1, 2015, our $350 million 3.45% Senior Notes matured, which we repaid using cash on hand. We have, therefore, classified these balances as “Current maturities of long-term debt” on our Consolidated Balance Sheet as of June 30, 2015. Our $300 million 3.05% Senior Notes mature during the first quarter of 2016. We anticipate using availability under our Credit Facilities to repay the outstanding balances; therefore, we continue to report these balances as long-term as of June 30, 2015. Covenants The Credit Facilities are guaranteed by NHIL and Noble Holding Corporation (“NHC”). The covenants and events of default under the two Credit Facilities are substantially similar, and each facility contains a covenant that limits our ratio of debt to total tangible capitalization, as defined in the Credit Facilities, to 0.60. At June 30, 2015, our ratio of debt to total tangible capitalization was approximately 0.40. We were in compliance with all covenants under the Credit Facilities as of June 30, 2015. In addition to the covenants from the Credit Facilities noted above, the indentures governing our outstanding senior unsecured notes contain covenants that place restrictions on certain merger and consolidation transactions, unless we are the surviving entity or the other party assumes the obligations under the indenture, and on the ability to sell or transfer all or substantially all of our assets. In addition, there are restrictions on incurring or assuming certain liens and on entering into sale and lease-back transactions. At June 30, 2015, we were in compliance with all of our debt covenants. We continually monitor compliance with the covenants under our notes and expect to remain in compliance during the remainder of 2015. Fair Value of Debt Fair value represents the amount at which an instrument could be exchanged in a current transaction between willing parties. The estimated fair value of our senior notes was based on the quoted market prices for similar issues or on the current rates offered to us for debt of similar remaining maturities (Level 2 measurement). All remaining fair value disclosures are presented in Note 12.

Income Taxes	Note 9 — Income Taxes At June 30, 2015, the reserves for uncertain tax positions totaled $112 million (net of related tax benefits of $1 million). If the June 30, 2015 reserves are not realized, the provision for income taxes would be reduced by $112 million. At December 31, 2014, the reserves for uncertain tax positions totaled $116 million (net of related tax benefits of $1 million). It is reasonably possible that our existing liabilities related to our reserve for uncertain tax positions may increase or decrease in the next 12 months primarily due to the completion of open audits or the expiration of statutes of limitation. However, we cannot reasonably estimate a range of changes in our existing liabilities due to various uncertainties, such as the unresolved nature of various audits.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Note 11 — Derivative Instruments and Hedging Activities We periodically enter into derivative instruments to manage our exposure to fluctuations in interest rates and foreign currency exchange rates. We have documented policies and procedures to monitor and control the use of derivative instruments. We do not engage in derivative transactions for speculative or trading purposes, nor are we a party to leveraged derivatives. For foreign currency forward contracts, hedge effectiveness is evaluated at inception based on the matching of critical terms between derivative contracts and the hedged item. Any change in fair value resulting from ineffectiveness is recognized immediately in earnings. Cash Flow Hedges Several of our regional shorebases, including our North Sea, Australian and Brazilian operations, have a significant amount of their cash operating expenses payable in local currencies. To limit the potential risk of currency fluctuations, we periodically enter into forward contracts, which settle monthly in the operations’ respective local currencies. All of these contracts have a maturity of less than 12 months. The forward contract settlements in the remainder of 2015 represent approximately 60 percent of these forecasted local currency requirements. The notional amount of the forward contracts outstanding, expressed in U.S. Dollars, was approximately $47 million at June 30, 2015. Total unrealized losses related to these forward contracts were approximately $0.1 million as of June 30, 2015 and were recorded as part of “Accumulated other comprehensive loss” (“AOCL”).

(“Petrobras”) drilling contracts. We understand that this agent has represented a number of different companies in Brazil over many years, including several offshore drilling contractors. Recent reports indicate that this agent has entered into a plea agreement in Brazil in connection with the award of a drilling contract to a competitor, and has implicated a Petrobras official as part of a wider investigation of Petrobras’ business practices. We are not aware of any improper activity by Noble in connection with contracts that Noble has entered into with Petrobras, and we have not been contacted by any authorities regarding such contracts or the investigation into Petrobras’ business practices. We are from time to time a party to various lawsuits that are incidental to our operations in which the claimants seek an unspecified amount of monetary damages for personal injury, including injuries purportedly resulting from exposure to asbestos on drilling rigs and associated facilities. At June 30, 2015, there were 45 asbestos related lawsuits in which we are one of many defendants. These lawsuits have been filed in the United States in the states of Louisiana, Mississippi and Texas. We intend to vigorously defend against the litigation. We do not believe the ultimate resolution of these matters will have a material adverse effect on our financial position, results of operations or cash flows. We are a defendant in certain claims and litigation arising out of operations in the ordinary course of business, the resolution of which, in the opinion of management, will not be material to our financial position, results of operations or cash flows. There is inherent risk in any litigation or dispute and no assurance can be given as to the outcome of these claims. We operate in a number of countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. During the first quarter of 2014, the IRS began its examination of our tax reporting in the U.S. for the taxable years ended December 31, 2010 and 2011. We believe that we have accurately reported all amounts in our 2010 and 2011 tax returns. We believe the ultimate resolution of the outstanding assessments in the U.S., for which we have not made any accrual, will not have a material adverse effect on our consolidated financial statements. We recognize uncertain tax positions that we believe have a greater than 50 percent likelihood of being sustained. We cannot predict or provide assurance as to the ultimate outcome of any existing or future assessments. Audit claims of approximately $110 million attributable to income, customs and other business taxes have been assessed against us in Mexico and Brazil. Tax assessments of approximately $52 million have been made against Noble entities in Mexico, of which approximately $38 million relates to Paragon Offshore assets that operated through Noble-retained entities in Mexico prior to the Spin-off. Paragon Offshore has received tax assessments of approximately $220 million against Paragon Offshore entities in Mexico, of which approximately $50 million relates to Noble assets that operated through Paragon Offshore-retained entities in Mexico prior to the Spin-off. In Brazil, Paragon Offshore has received tax assessments of approximately $150 million, of which $46 million relates to Noble assets that operated through a Paragon Offshore-retained entity in Brazil prior to the Spin-off. Under the TSA, Paragon Offshore must indemnify us for all assessed amounts that are related to Paragon Offshore’s Mexico assets, approximately $38 million as noted above, and we must indemnify Paragon Offshore for all assessed amounts that are related to Noble’s Mexico and Brazil assets, approximately $50 million and $46 million, respectively, as noted above, if and when such payments become due. We have contested, or intend to contest or cooperate with Paragon Offshore where it is contesting, the assessments described above, including through litigation if necessary, and we believe the ultimate resolution, for which we have not made any accrual, will not have a material adverse effect on our consolidated financial statements. Tax authorities may issue additional assessments or pursue legal actions as a result of tax audits and we cannot predict or provide assurance as to the ultimate outcome of such assessments and legal actions or our ability to collect indemnities from Paragon Offshore under the TSA. On January 23, 2015, Noble received an official notification of a ruling from the Second Chamber of the Supreme Court in Mexico. The ruling settled an ongoing dispute in Mexico relating to the classification of a Noble subsidiary’s business activity and the applicable rate of depreciation under the Mexican law applicable to the activities of that subsidiary. The ruling did not result in any additional tax liability to Noble. Additionally, the ruling is only applicable to the Noble subsidiary named in the ruling and, therefore, does not establish the depreciation rate applicable to the assets of other Noble subsidiaries. We will continue to contest future assessments received. Any claim by the tax authorities relating to this depreciation issue would be related to the businesses transferred to Paragon Offshore in the Spin-off and, therefore, would be subject to indemnification by Paragon Offshore under the TSA. We have been notified by Petrobras that it is currently challenging assessments by Brazilian tax authorities of withholding taxes associated with the provision of drilling rigs for its operations in Brazil during 2008 and 2009. Petrobras has also notified us that if Petrobras must ultimately pay such withholding taxes, it will seek reimbursement from us for the portion allocable to our drilling rigs. The amount of withholding tax that Petrobras indicates may be allocable to Noble drilling rigs is R$79 million (approximately $25 million). We believe that our contract with Petrobras requires Petrobras to indemnify us for these withholding taxes. We will, if necessary, vigorously defend our rights. We maintain certain insurance coverage against specified marine perils, which includes physical damage and loss of hire. The rigs in the U.S. Gulf of Mexico are self-insured for named windstorm perils. In addition, we maintain a physical damage deductible on our rigs of $25 million per occurrence. The loss of hire coverage applies only to our rigs operating under contract with a dayrate equal to or greater than $200,000 a day and is subject to a 45-day waiting period for each unit and each occurrence. Although we maintain insurance in the geographic areas in which we operate, pollution, reservoir damage and environmental risks generally are not fully insurable. Our insurance policies and contractual rights to indemnity may not adequately cover our losses or may have exclusions of coverage for some losses. We do not have insurance coverage or rights to indemnity for all risks, including loss of hire insurance on most of the rigs in our fleet. Uninsured exposures may include expatriate activities prohibited by U.S. laws and regulations, radiation hazards, certain loss or damage to property on board our rigs and losses relating to shore-based terrorist acts, strikes or cyber risks. If a significant accident or other event occurs and is not fully covered by insurance or contractual indemnity, it could materially adversely affect our financial position, results of operations or cash flows. Additionally, there can be no assurance that those parties with contractual obligations to indemnify us will necessarily be financially able to indemnify us against all these risks. We carry protection and indemnity insurance covering marine third party liability exposures, which also includes coverage for employer’s liability resulting from personal injury to our offshore drilling crews. Our protection and indemnity policy currently has a standard deductible of $10 million per occurrence, with maximum liability coverage of $750 million. In connection with our capital expenditure program, we had outstanding commitments, including shipyard and purchase commitments of approximately $697 million at June 30, 2015. We have entered into agreements with certain of our executive officers, as well as certain other employees. These agreements become effective upon a change of control of Noble-UK (within the meaning set forth in the agreements) or a termination of employment in connection with or in anticipation of a change of control, and remain effective for three years thereafter. These agreements provide for compensation and certain other benefits under such circumstances.

Accounting Changes and Error Corrections [Abstract]
Accounting Pronouncements	Note 15 — Accounting Pronouncements In April 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-08, which amends FASB Accounting Standards Codification (“ASC”) Topic 205, “Presentation of Financial Statements” and ASC Topic 360, “Property, Plant, and Equipment.” This ASU alters the definition of a discontinued operation to cover only asset disposals that are a strategic shift with a major effect on an entity’s operations and finances, and calls for more extensive disclosures about a discontinued operation’s assets, liabilities, income and expenses. The guidance is effective for all disposals, or classifications as held-for-sale, of components of an entity that occur within annual periods beginning on or after December 15, 2014. This standard was not early adopted in connection with the Spin-Off. The adoption of this guidance did not have a material impact on our financial condition, results of operations, cash flows or financial disclosures. In May 2014, the FASB issued ASU No. 2014-09, which amends ASC Topic 606, “Revenue from Contracts with Customers.” The amendments in this ASU are intended to provide a more robust framework for addressing revenue issues, improve comparability of revenue recognition practices and improve disclosure requirements. Under the deferred adoption date, the new guidance will be effective for interim and annual reporting periods beginning after December 15, 2017. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In June 2014, the FASB issued ASU No. 2014-12, which amends ASC Topic 718, “Compensation-Stock Compensation.” The guidance requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition and should not be reflected in the estimate of the grant-date fair value of the award. The guidance is effective for annual periods beginning after December 15, 2015. The guidance can be applied prospectively for all awards granted or modified after the effective date or retrospectively to all awards with performance targets outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In August 2014, the FASB issued ASU No. 2014-15, which amends ASC Subtopic 205-40, “Disclosure of Uncertainties about an Entity’s Ability to continue as a Going Concern.” The amendments in this ASU provide guidance related to 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. The amendments are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In January 2015, the FASB issued ASU No. 2015-01, which amends ASC Subtopic 225-20, “Income Statement – Extraordinary and Unusual Items.” The amendment in this ASU eliminates from GAAP the concept of extraordinary items. The amendments in this update are effective for interim and annual reporting periods beginning after December 15, 2015. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In February 2015, the FASB issued ASU No. 2015-02 which amends ASC Subtopic 810, “Consolidations.” This amendment affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities; eliminate the presumption that a general partner should consolidate a limited partnership; affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. The standard is effective for interim and annual reporting periods beginning after December 15, 2015. The standard may be applied retrospectively or through a cumulative effect adjustment to retained earnings as of the beginning of the year of adoption. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In April 2015, the FASB issued ASU No. 2015-03 which amends ASC Subtopic 835-30, “Interest – Imputation of Interest.” The guidance requires debt issuance costs to be presented in the balance sheet as a direct reduction from the associated debt liability. The standard is effective for interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. The new guidance will be applied on a retrospective basis. We are evaluating what impact the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In April 2015, the FASB issued ASU No. 2015-04 which amends ASC Topic 715, “Compensation – Retirement Benefits.” The guidance gives an employer whose fiscal year end does not coincide with a calendar month end the ability, as a practical expedient, to measure defined benefit retirement obligations and related plan assets as of the month end that is closest to its fiscal year end. The ASU also provides a similar practical expedient for interim remeasurements of significant events. The standard is effective for interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures.

Supplemental Financial Information	Note 16 — Supplemental Financial Information Consolidated Balance Sheets Information Deferred revenues from drilling contracts totaled $223 million and $263 million at June 30, 2015 and December 31, 2014, respectively. Such amounts are included in either “Other current liabilities” or “Other liabilities” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition. Related expenses deferred under drilling contracts totaled $90 million at June 30, 2015 as compared to $94 million at December 31, 2014, and are included in either “Prepaid expenses and other current assets” or “Other assets” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition. In April 2015, we agreed to contract dayrate reductions for five rigs working for Saudi Arabian Oil Company (“Aramco”), which are effective from January 1, 2015 through December 31, 2015. In accordance with accounting guidance, we are recognizing the reductions on a straight-line basis over the remaining life of the existing Aramco contracts. At June 30, 2015, revenues recorded in excess of billings as a result of this recognition totaled $37 million, and are included in “Other assets” in the accompanying Consolidated Balance Sheets.

Accounting Changes and Error Corrections [Abstract]
Accounting Pronouncements	In April 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-08, which amends FASB Accounting Standards Codification (“ASC”) Topic 205, “Presentation of Financial Statements” and ASC Topic 360, “Property, Plant, and Equipment.” This ASU alters the definition of a discontinued operation to cover only asset disposals that are a strategic shift with a major effect on an entity’s operations and finances, and calls for more extensive disclosures about a discontinued operation’s assets, liabilities, income and expenses. The guidance is effective for all disposals, or classifications as held-for-sale, of components of an entity that occur within annual periods beginning on or after December 15, 2014. This standard was not early adopted in connection with the Spin-Off. The adoption of this guidance did not have a material impact on our financial condition, results of operations, cash flows or financial disclosures. In May 2014, the FASB issued ASU No. 2014-09, which amends ASC Topic 606, “Revenue from Contracts with Customers.” The amendments in this ASU are intended to provide a more robust framework for addressing revenue issues, improve comparability of revenue recognition practices and improve disclosure requirements. Under the deferred adoption date, the new guidance will be effective for interim and annual reporting periods beginning after December 15, 2017. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In June 2014, the FASB issued ASU No. 2014-12, which amends ASC Topic 718, “Compensation-Stock Compensation.” The guidance requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition and should not be reflected in the estimate of the grant-date fair value of the award. The guidance is effective for annual periods beginning after December 15, 2015. The guidance can be applied prospectively for all awards granted or modified after the effective date or retrospectively to all awards with performance targets outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In August 2014, the FASB issued ASU No. 2014-15, which amends ASC Subtopic 205-40, “Disclosure of Uncertainties about an Entity’s Ability to continue as a Going Concern.” The amendments in this ASU provide guidance related to 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. The amendments are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In January 2015, the FASB issued ASU No. 2015-01, which amends ASC Subtopic 225-20, “Income Statement – Extraordinary and Unusual Items.” The amendment in this ASU eliminates from GAAP the concept of extraordinary items. The amendments in this update are effective for interim and annual reporting periods beginning after December 15, 2015. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In February 2015, the FASB issued ASU No. 2015-02 which amends ASC Subtopic 810, “Consolidations.” This amendment affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities; eliminate the presumption that a general partner should consolidate a limited partnership; affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. The standard is effective for interim and annual reporting periods beginning after December 15, 2015. The standard may be applied retrospectively or through a cumulative effect adjustment to retained earnings as of the beginning of the year of adoption. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In April 2015, the FASB issued ASU No. 2015-03 which amends ASC Subtopic 835-30, “Interest – Imputation of Interest.” The guidance requires debt issuance costs to be presented in the balance sheet as a direct reduction from the associated debt liability. The standard is effective for interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. The new guidance will be applied on a retrospective basis. We are evaluating what impact the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. In April 2015, the FASB issued ASU No. 2015-04 which amends ASC Topic 715, “Compensation – Retirement Benefits.” The guidance gives an employer whose fiscal year end does not coincide with a calendar month end the ability, as a practical expedient, to measure defined benefit retirement obligations and related plan assets as of the month end that is closest to its fiscal year end. The ASU also provides a similar practical expedient for interim remeasurements of significant events. The standard is effective for interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures.
