Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES As of September 30, 2015, Apache’s significant accounting policies are consistent with those discussed in Note 1—Summary of Significant Accounting Policies to the consolidated financial statements contained in Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates with regard to these financial statements include the fair value determination of acquired assets and liabilities, the estimate of proved oil and gas reserves and related present value estimates of future net cash flows therefrom, assessing asset retirement obligations, and the estimate of income taxes. Actual results could differ from those estimates. Oil and Gas Property The Company follows the full-cost method of accounting for its oil and gas property. Under this method of accounting, all costs incurred for both successful and unsuccessful exploration and development activities, including salaries, benefits and other internal costs directly identified with these activities, and oil and gas property acquisitions are capitalized. The net book value of oil and gas properties, less related deferred income taxes, may not exceed a calculated “ceiling.” The ceiling limitation is the estimated after-tax future net cash flows from proved oil and gas reserves, discounted at 10 percent per annum and adjusted for designated cash flow hedges. Estimated future net cash flows are calculated using end-of-period costs and an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of the production, except where prices are defined by contractual arrangements. For a discussion of the calculation of estimated future net cash flows, please refer to Note 14—Supplemental Oil and Gas Disclosures to the consolidated financial statements contained in Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. Any excess of the net book value of proved oil and gas properties, less related deferred income taxes, over the ceiling is charged to expense and reflected as “Additional depreciation, depletion, and amortization” (DD&A) in the accompanying statement of consolidated operations. Such limitations are imposed separately on a country-by-country basis and are tested quarterly. The following tables present non-cash write-downs of the carrying value of the Company’s proved oil and gas properties by country for the third quarter and first nine months of 2015 and 2014: For the Quarter Ended For the Quarter Ended Before tax After tax Before tax After tax (In millions) U.S. $ 4,301 $ 2,774 $ 1,545 $ 995 Canada 973 719 — — North Sea 447 223 17 7 Total impairment $ 5,721 $ 3,716 $ 1,562 $ 1,002 For the Nine Months Ended For the Nine Months Ended Before tax After tax Before tax After tax (In millions) U.S. $ 13,855 $ 8,937 $ 1,545 $ 995 Canada 3,160 2,347 — — North Sea 1,742 871 220 84 Total impairment $ 18,757 $ 12,155 $ 1,765 $ 1,079 Asset Impairments For the quarter and nine months ended September 30, 2015, the Company recorded asset impairments totaling $367 million in connection with fair value assessments. Impairments included $210 million on certain gathering, transmission, and processing (GTP) facilities, which were written down to their fair values of $16 million in aggregate. The fair values of the impaired assets were determined using an income approach, which considered internal estimates of future throughput volumes, processing rates, and costs. These assumptions were applied to develop future cash flow projections that were then discounted to estimate fair value, using a discount rate believed to be consistent with those applied by market participants. Apache has classified these non-recurring fair value measurements as Level 3 in the fair value hierarchy. In addition, the Company recorded $148 million for the impairment of an equity method investment and $9 million for inventory write-downs. For discussion of the equity method investment impairment, see Note 2—Acquisitions and Divestitures. New Pronouncements Issued But Not Yet Adopted In September 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-16, which 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, including amounts it would have recorded in previous periods if the accounting had been completed at the acquisition date. ASU 2015-16 is effective for fiscal years beginning after December 15, 2016. The Company does not expect the adoption of this amendment to have a material impact on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, which simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. Entities will continue to apply their existing impairment models to inventories that are accounted for using last-in first-out and the retail inventory method. Under current guidance, net realizable value is one of several calculations an entity needs to make to measure inventory at the lower of cost or market. The guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company does not expect the adoption of this amendment to have a material impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, which simplifies the presentation of debt issuance costs. The new standard requires debt issuance costs to be presented as a direct deduction from the carrying value of the associated debt liability, whereas they are currently being presented as a component of “deferred charges and other” on the balance sheet. The new standard creates consistency in the way debt issuance costs and debt discounts are presented on the balance sheet and better aligns U.S. GAAP with International Financial Reporting Standards. ASU 2015-03 is effective for annual and interim reporting periods beginning after December 15, 2015. The Company will apply the change retrospectively and does not expect the adoption of this amendment to have a material impact on its consolidated financial statements. In May 2014, the FASB and the International Accounting Standards Board (IASB) issued a joint revenue recognition standard, ASU 2014-09. The new standard removes inconsistencies in existing standards, changes the way companies recognize revenue from contracts with customers, and increases disclosure requirements. The guidance requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. In July 2015, the FASB announced a delay in the effective date of the revenue standard by one year. The deferral results in the new revenue standard being effective for annual and interim periods beginning after December 15, 2017. The standard is required to be adopted using either the full retrospective approach, with all prior periods presented adjusted, or the modified retrospective approach, with a cumulative adjustment to retained earnings on the opening balance sheet. The Company is currently evaluating the level of effort needed to implement the standard, the impact of adopting this standard on its consolidated financial statements, and whether to use the full retrospective approach or the modified retrospective approach.

Acquisitions and Divestitures	2. ACQUISITIONS AND DIVESTITURES 2015 Activity Yara Pilbara Holdings Pty Limited Sale On October 28, 2015, Apache completed the sale of its 49 percent interest in Yara Pilbara Holdings Pty Limited (YPHPL) for total cash proceeds of $391 million. The investment in YPHPL was accounted for under the equity method of accounting, with the balance recorded as a component of “Deferred charges and other” in Apache’s consolidated balance sheet and the results of operations recorded as a component of “Other” under “Revenue and other” in the Company’s statement of consolidated operations. As of September 30, 2015, Apache recognized an impairment of $148 million on the YPHPL equity investment based on negotiated sales proceeds. No additional gain or loss was recorded upon completion of the sale. Canada Divestiture In April 2015, Apache completed the sale of its 50 percent interest in the Kitimat LNG project and related upstream acreage in the Horn River and Liard natural gas basins to Woodside Petroleum Limited (Woodside). Proceeds at closing were $854 million, of which approximately $345 million were associated with LNG assets and $510 million were associated with upstream assets. The proceeds are subject to post-closing adjustments. For additional details related to post-closing adjustments, please see Note 7—Commitments and Contingencies. The Kitimat LNG assets were impaired in the fourth quarter of 2014 and classified as held for sale on the consolidated balance sheet as of December 31, 2014. No material gain or loss was recognized for the LNG assets upon completion of the sale. No gain or loss was recognized on the sale of the upstream assets. In accordance with full cost accounting rules, sales of oil and gas properties are accounted for as adjustments of capitalized costs, with no gain or loss recognized unless such adjustment would significantly alter the relationship between capitalized costs and proved reserves. Australia Divestitures Woodside Sale The Wheatstone LNG assets were impaired in the fourth quarter of 2014 and classified as held for sale on the consolidated balance sheet as of December 31, 2014. No material gain or loss was recognized on the ultimate disposal of the LNG project. A loss of approximately $922 million was recognized on the sale of the Australian upstream assets. Consortium Sale Upon closing of the sale of substantially all Australian operations, the associated results of operations for the divested Australian assets and the losses on disposal were classified as discontinued operations in all periods presented in this Quarterly Report on Form 10-Q. The carrying amounts of the major classes of consolidated assets and liabilities associated with the Australia dispositions were as follows: December 31, ASSETS Current assets $ 1,992 Net property and equipment 6,516 Total assets $ 8,508 LIABILITIES Current liabilities $ 606 Asset retirement obligations 517 Non-current deferred tax liability 922 Other long-term liabilities 33 Total liabilities $ 2,078 Sales and other operating revenues and loss from discontinued operations related to the Australia dispositions were as follows: For the Quarter Ended For the Nine Months Ended 2015 2014 2015 2014 (In millions) Revenues and other from discontinued operations $ — $ 299 $ 288 $ 781 Loss on Woodside sale $ — $ — $ (922 ) $ — Loss on Consortium sale — — (1,329 ) — Income from divested Australian operations — 99 24 317 Income tax benefit (expense) (95 ) (255 ) 1,268 (316 ) Income (loss) from Australian discontinued operations, net of tax $ (95 ) $ (156 ) $ (959 ) $ 1 Leasehold and Property Acquisitions During the third quarter and first nine months of 2015, Apache completed $126 million and $254 million, respectively, of leasehold and property acquisitions primarily in our North America onshore regions.

In the Anadarko basin, Apache sold approximately 115,000 net acres in Wheeler County, Texas, and western Oklahoma. In southern Louisiana, Apache sold its working interest in approximately 90,000 net acres. The effective date of both of these transactions was October 1, 2014. Gulf of Mexico Divestiture On June 30, 2014, Apache completed the sale of non-operated interests in the Lucius and Heidelberg development projects and 11 primary-term deepwater exploration blocks in the Gulf of Mexico for $1.4 billion. The effective date of the transaction was May 1, 2014. Canada Divestiture On April 30, 2014, Apache completed the sale of producing oil and gas assets in the Deep Basin area of western Alberta and British Columbia, Canada, for $374 million. Apache sold primarily dry-gas producing properties comprising 328,400 net acres in the Ojay, Noel, and Wapiti areas. In the Wapiti area, Apache retained 100 percent of its working interest in horizons below the Cretaceous, including rights to the liquids-rich Montney and other deeper horizons. The effective date of the transaction was January 1, 2014. Argentina Divestiture On March 12, 2014, Apache’s subsidiaries completed the sale of all of the Company’s operations in Argentina to YPF Sociedad Anónima for cash consideration of $800 million plus the assumption of $52 million of bank debt as of June 30, 2013. The results of operations during 2014 related to Argentina have been classified as discontinued operations in this Quarterly Report on Form 10-Q. The 2014 loss from Argentina discontinued operations of $517 million is included in “Net income (loss) from discontinued operations, net of tax” on the statement of consolidated operations.

Debt and Financing Costs	5. DEBT AND FINANCING COSTS The following table presents the carrying amounts and estimated fair values of the Company’s outstanding debt: September 30, 2015 December 31, 2014 Carrying Amount Fair Value Carrying Amount Fair Value (In millions) Commercial paper and committed bank facilities $ — $ — $ 1,570 $ 1,570 Notes and debentures 8,777 8,829 9,675 9,944 Total Debt $ 8,777 $ 8,829 $ 11,245 $ 11,514 The Company’s debt is recorded at the carrying amount, net of unamortized discount, on its consolidated balance sheet. The carrying amount of the Company’s commercial paper, committed bank facilities and uncommitted bank lines, and overdraft lines approximates fair value because the interest rates are variable and reflective of market rates. Apache uses a market approach to determine the fair value of its notes and debentures using estimates provided by an independent investment financial data services firm (a Level 2 fair value measurement). In June 2015, the Company entered into a $3.5 billion five-year revolving credit facility which matures in June 2020. Proceeds from borrowings may be used for general corporate purposes. Apache’s available borrowing capacity under this facility supports its commercial paper program. In connection with entry into the $3.5 billion facility, Apache terminated existing credit facilities totaling $5.3 billion. The Company has available a $3.5 billion commercial paper program, which generally enables Apache to borrow funds for up to 270 days at competitive interest rates. As of September 30, 2015, the Company had no debt outstanding under commercial paper, committed bank facilities, and uncommitted bank lines. On September 1, 2015, the Company fully redeemed its $500 million 5.625% notes due in 2017 and its $400 million 1.75% notes due in 2017. The notes were redeemed pursuant to the provisions of each respective note’s indenture. Apache paid the holders an aggregate of $939 million in cash reflecting principal and the premium to par, and an additional $8 million in accrued and unpaid interest.

Income Tax Disclosure [Abstract]
Income Taxes	6. INCOME TAXES The Company estimates its annual effective income tax rate for continuing operations in recording its quarterly provision for income taxes in the various jurisdictions in which the Company operates. Non-cash write-downs of the carrying value of the Company’s proved oil and gas properties, statutory tax rate changes, and other significant or unusual items are recognized as discrete items in the quarter in which they occur. During the third quarter of 2015 Apache’s effective tax rate was primarily impacted by an increase in the amount of valuation allowances. With the further commodity price declines since the second quarter, management continues to assess the potential realization of its deferred tax assets. In the third quarter, the Company recorded a deferred tax expense of $1.1 billion and $69 million related to an increase in valuation allowances associated with U.S. foreign tax credits and net operating loss carryforwards, respectively. In addition to the allowance recorded during the third quarter, the Company had previously recorded tax expense of $853 million in the second quarter of 2015 related to an increase in valuation allowance associated with management’s assessment on the realizability of U.S. foreign tax credits subsequent to repatriating the majority of net cash proceeds from the Kitimat LNG project and Australia divestitures. Apache’s year-to-date effective tax rate is primarily driven by the increase in U.S. valuation allowances described above and an increase in the valuation allowance on Canadian deferred tax assets, partially offset by a first-quarter 2015 deferred tax benefit from the previously announced U.K. tax rate change.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	7. COMMITMENTS AND CONTINGENCIES Legal Matters Apache is party to various legal actions arising in the ordinary course of business, including litigation and governmental and regulatory controls. As of September 30, 2015, the Company has an accrued liability of approximately $20 million for all legal contingencies that are deemed to be probable of occurring and can be reasonably estimated. Apache’s estimates are based on information known about the matters and its experience in contesting, litigating, and settling similar matters. Although actual amounts could differ from management’s estimate, none of the actions are believed by management to involve future amounts that would be material to Apache’s financial position, results of operations, or liquidity after consideration of recorded accruals. For material matters that Apache believes an unfavorable outcome is reasonably possible, the Company has disclosed the nature of the matter and a range of potential exposure, unless an estimate cannot be made at this time. It is management’s opinion that the loss for any other litigation matters and claims that are reasonably possible to occur will not have a material adverse effect on the Company’s financial position, results of operations, or liquidity. For additional information on each of the Legal Matters described below, please see Note 8—Commitments and Contingencies to the consolidated financial statements contained in Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. Argentine Environmental Claims and Argentina Tariff No material change in the status of the YPF Sociedad Anónima and Pioneer Natural Resources Company indemnities matters has occurred since the filing of Apache’s Annual Report on Form 10-K for its 2014 fiscal year. Louisiana Restoration As more fully described in Apache’s Annual Report on Form 10-K for its 2014 fiscal year, numerous surface owners have filed claims or sent demand letters to various oil and gas companies, including Apache, claiming that, under either expressed or implied lease terms or Louisiana law, the companies are liable for damage measured by the cost of restoration of leased premises to their original condition as well as damages for contamination and cleanup. In a case captioned State of Louisiana and the Cameron Parish School Board v. Apache Corporation et al. th In respect of three lawsuits filed by the Parish of Plaquemines against the Company and other oil and gas producers in the 25 th Parish of Plaquemines v. Rozel Operating Company et al., Parish of Plaquemines v. Apache Oil Corporation et al., Parish of Plaquemines v. HHE Energy Company et al., No other material change in the status of these matters has occurred since the filing of Apache’s Annual Report on Form 10-K for its 2014 fiscal year. Australia Gas Pipeline Force Majeure In 2008, Company subsidiaries reported a pipeline explosion that interrupted deliveries of natural gas in Australia to customers under various long-term contracts. The civil lawsuits concerning the pipeline explosion, all of which were filed in the Supreme Court of Western Australia, have been resolved fully and dismissed on confidential terms, including for an exchange of consideration that is not material to Apache. The lawsuits are described in Apache’s Annual Report on Form 10-K for its 2014 fiscal year. On April 10, 2015, the court dismissed the lawsuits filed by plaintiffs Alcoa (Civ. 1481 of 2011), Barrick (Civ. 2656 of 2013), EDL LNG (Civ. 1751 of 2014), and Yara (Civ. 1742 of 2014). On April 9, 2015, plaintiffs Harvey (Civ. 1749 of 2014), Iluka (Civ. 1748 of 2014), Newmont (Civ. 1727 of 2014), and Wesfarmers (Civ. 1740 of 2014) discontinued their lawsuits, which were never served on the Apache defendants. All matters relating to the Australia gas pipeline force majeure are concluded. Apollo Exploration Lawsuit In a second amended petition filed on February 27, 2015, in a case captioned Apollo Exploration, LLC, Cogent Exploration, Ltd. Co. & SellmoCo, LLC v. Apache Corporation th Escheat Audits As part of its ongoing review of the books and records of the Company to determine the Company’s compliance with Delaware Escheat Laws, the State of Delaware, Department of Finance (Unclaimed Property) has advised the Company, by letter dated September 30, 2015, that the liability related to disbursements due to the State of Delaware for the years 2004 through 2009 is less than $237,000 and that its review for the years 1986 through 2003 is not complete. The exposure for the years 1986 through 2003 is not currently determinable. The Company will review the claim for the years 2004 through 2009, respond to the September 30 letter in due course, and continue to cooperate fully until the review is complete. There has been no other material change with respect to the review of the books and records of the Company and its subsidiaries and related entities by the State of Delaware, Department of Finance (Unclaimed Property), to determine compliance with the Delaware Escheat Laws, since the filing of Apache’s Annual Report on Form 10-K for its 2014 fiscal year. Burrup-Related Gas Supply Lawsuits In the lawsuit captioned Pankaj Oswal v. Apache Corporation In the cases captioned Radhika Oswal v. Australia and New Zealand Banking Group Limited et al. Pankaj Oswal v. Australia and New Zealand Banking Group Limited et al. Environmental Matters As of September 30, 2015, the Company had an undiscounted reserve for environmental remediation of approximately $62 million. The Company is not aware of any environmental claims existing as of September 30, 2015, that have not been provided for or would otherwise have a material impact on its financial position, results of operations, or liquidity. There can be no assurance, however, that current regulatory requirements will not change or past non-compliance with environmental laws will not be discovered on the Company’s properties. With respect to the June 1, 2013, leak of produced water from a below ground pipeline in the Zama Operations area in northern Alberta, the Alberta Energy Regulator has completed its investigation of the incident and issued an administrative penalty to Apache Canada Ltd. in the amount of $16,500 CAD. On October 19, 2015, the Crown served Apache Canada Ltd. with a notice to attend to answer a charge relating to a leak of produced water in the Zama area that occurred on or between October 3, 2013 and October 25, 2013. The leak resulted from a riser that was damaged by force by an independent agent following Apache Canada Ltd.’s discontinued use of the pipeline segment. The seven-count charge could result in the levying of a fine. Apache Canada Ltd. will review the charge and respond in due course. It is possible that additional discharges in Apache Canada Ltd. operating areas, including in the Zama Operations area, could result in additional government fines or sanction. No other material change in the status of these matters has occurred since the filing of Apache’s Annual Report on Form 10-K for its 2014 fiscal year. LNG Divestiture Dispute In respect of the purchase by Woodside of the Wheatstone and Kitimat LNG projects and accompanying upstream oil and gas reserves from the Company and its subsidiaries, the base purchase price is subject to adjustment in accordance with the terms of the applicable sale and purchase agreement. Woodside has notified the Company and its subsidiaries that it seeks purchase price adjustments in the net amounts of $175 million (for working capital adjustments), which the Company and its subsidiaries believe is time-barred, and $214 million (for all other adjustments). To the extent the parties are unable to resolve their differences through settlement or court proceedings, the dispute will be referred to an independent accounting expert for final determination under the terms of the applicable sale and purchase agreement. The Company believes that under the terms of the sale and purchase agreements, Woodside’s requests for payment of purchase price adjustments lack merit; therefore, the Company has not recorded a liability associated with this dispute.

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates with regard to these financial statements include the fair value determination of acquired assets and liabilities, the estimate of proved oil and gas reserves and related present value estimates of future net cash flows therefrom, assessing asset retirement obligations, and the estimate of income taxes. Actual results could differ from those estimates.
Oil and Gas Property	Oil and Gas Property The Company follows the full-cost method of accounting for its oil and gas property. Under this method of accounting, all costs incurred for both successful and unsuccessful exploration and development activities, including salaries, benefits and other internal costs directly identified with these activities, and oil and gas property acquisitions are capitalized. The net book value of oil and gas properties, less related deferred income taxes, may not exceed a calculated “ceiling.” The ceiling limitation is the estimated after-tax future net cash flows from proved oil and gas reserves, discounted at 10 percent per annum and adjusted for designated cash flow hedges. Estimated future net cash flows are calculated using end-of-period costs and an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of the production, except where prices are defined by contractual arrangements. For a discussion of the calculation of estimated future net cash flows, please refer to Note 14—Supplemental Oil and Gas Disclosures to the consolidated financial statements contained in Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. Any excess of the net book value of proved oil and gas properties, less related deferred income taxes, over the ceiling is charged to expense and reflected as “Additional depreciation, depletion, and amortization” (DD&A) in the accompanying statement of consolidated operations. Such limitations are imposed separately on a country-by-country basis and are tested quarterly. The following tables present non-cash write-downs of the carrying value of the Company’s proved oil and gas properties by country for the third quarter and first nine months of 2015 and 2014: For the Quarter Ended For the Nine Months Ended Before tax After tax Before tax After tax (In millions) U.S. $ 4,301 $ 2,774 $ 13,855 $ 8,937 Canada 973 719 3,160 2,346 North Sea 447 224 1,742 871 Total impairment $ 5,721 $ 3,717 $ 18,757 $ 12,154 For the Quarter Ended For the Nine Months Ended Before tax After tax Before tax After tax (In millions) U.S. $ 1,545 $ 995 $ 1,545 $ 995 North Sea 17 7 220 84 Total impairment $ 1,562 $ 1,002 $ 1,765 $ 1,079
New Pronouncements Issued But Not Yet Adopted	New Pronouncements Issued But Not Yet Adopted In September 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-16, which 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, including amounts it would have recorded in previous periods if the accounting had been completed at the acquisition date. ASU 2015-16 is effective for fiscal years beginning after December 15, 2016. The Company does not expect the adoption of this amendment to have a material impact on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, which simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. Entities will continue to apply their existing impairment models to inventories that are accounted for using last-in first-out and the retail inventory method. Under current guidance, net realizable value is one of several calculations an entity needs to make to measure inventory at the lower of cost or market. The guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company does not expect the adoption of this amendment to have a material impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, which simplifies the presentation of debt issuance costs. The new standard requires debt issuance costs to be presented as a direct deduction from the carrying value of the associated debt liability, whereas they are currently being presented as a component of “deferred charges and other” on the balance sheet. The new standard creates consistency in the way debt issuance costs and debt discounts are presented on the balance sheet and better aligns U.S. GAAP with International Financial Reporting Standards. ASU 2015-03 is effective for annual and interim reporting periods beginning after December 15, 2015. The Company will apply the change retrospectively and does not expect the adoption of this amendment to have a material impact on its consolidated financial statements. In May 2014, the FASB and the International Accounting Standards Board (IASB) issued a joint revenue recognition standard, ASU 2014-09. The new standard removes inconsistencies in existing standards, changes the way companies recognize revenue from contracts with customers, and increases disclosure requirements. The guidance requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. In July 2015, the FASB announced a delay in the effective date of the revenue standard by one year. The deferral results in the new revenue standard being effective for annual and interim periods beginning after December 15, 2017. The standard is required to be adopted using either the full retrospective approach, with all prior periods presented adjusted, or the modified retrospective approach, with a cumulative adjustment to retained earnings on the opening balance sheet. The Company is currently evaluating the level of effort needed to implement the standard, the impact of adopting this standard on its consolidated financial statements, and whether to use the full retrospective approach or the modified retrospective approach.
