APACHE CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) As of December 31, 2012, the Company had an undiscounted reserve for environmental remediation of approximately $104 million.
Apache is not aware of any environmental claims existing as of December 31, 2012 that have not been provided for or would otherwise have a material impact on its financial position or results of operations.
There can be no assurance however, that current regulatory requirements will not change or past noncompliance with environmental laws will not be discovered on the Company’s properties.
Apache Canada Ltd.  asserted a claim against BP Canada arising out of the acquisition of certain Canadian properties under the parties’ Partnership Interest and Share Purchase and Sale Agreement dated July 20, 2010.
The claim centered on Apache Canada Ltd. ’s identification of Alleged Adverse Conditions, as that term is defined in the parties’ agreement, and more specifically the contention that liabilities associated with such conditions were retained by BP Canada as seller.
The parties have resolved the matter on commercial terms with no material impact on the Company’s financial position, results of operations, or liquidity.
On May 25, 2011, a panel of the Bureau of Ocean Energy Management (BOEMRE, as it was then known) published a report dated May 23, 2011, and titled “OCS G-2580, Vermilion Block 380 Platform A, Incidents of Noncompliance.
” The report concerned the BOEMRE’s investigation of a fire on the Vermilion 380 A platform located in the Gulf of Mexico.
At the time of the incident, Mariner operated the platform.
A small amount of hydrocarbons spilled from the platform into the surrounding water as a result of the incident, and 13 workers were rescued after evacuating the platform.
The BOEMRE concluded in its investigation that the fire was caused by Mariner’s failure to adequately maintain or operate the platform’s heater-treater in a safe condition.
The BOEMRE also identified other safety deficiencies on the platform.
On December 27, 2011, the Bureau of Safety and Environmental Enforcement (BSEE, successor to BOEMRE) issued several Incidents of Non-Compliance, which may provide the basis for the assessment of civil penalties against Mariner.
The Company’s subsidiary Apache Deepwater LLC, which acquired Mariner effective November 10, 2010, filed an appeal on August 31, 2012, contesting several of the Incidents of Non-Compliance.
It is management’s opinion that any loss arising from this matter will not have a material adverse effect on the Company’s financial position, results of operations, or liquidity.
Contractual Obligations At December 31, 2012, contractual obligations for drilling rigs, purchase obligations, firm transportation agreements, and long-term operating leases are as follows:
## Table 0 ##
(1) Includes day-rate and other contractual agreements with third party service providers for use of drilling, completion, and workover rigs.
(2) Includes contractual obligations to buy or build oil and gas plants and facilities, LNG facilities, seismic and drilling work program commitments, take-or-pay contracts, and hydraulic fracturing services agreements.
(3) Relates to contractual obligations for capacity rights on third-party pipelines.
Production
## Table 1 ##
(1) Approximately 13 percent of 2012 worldwide oil production was subject to financial derivative hedges, compared to 29 percent in 2011 and 12 percent in 2010.
(2) Approximately 13 percent of 2012 worldwide natural gas production was subject to financial derivative hedges, compared to 16 percent in 2011 and 23 percent in 2010.
(3) Gross oil production in Egypt for 2012, 2011, and 2010 was 213,112 b/d, 217,207 b/d, and 189,342 b/d, respectively.
Gross natural gas production in Egypt for 2012, 2011, and 2010 was 899,972 Mcf/d, 865,485 Mcf/d, and 798,645 Mcf/d, respectively.
(4) The table shows production on a barrel of oil equivalent basis (boe) in which natural gas is converted to an equivalent barrel of oil based on a 6:1 energy equivalent ratio.
This ratio is not reflective of the price ratio between the two products.

APACHE CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued) In November 2015, the FASB issued ASU 2015-17 “Balance Sheet Classification of Deferred Taxes,” which requires all companies to classify deferred tax assets, liabilities, and related valuation allowances as noncurrent on the balance sheet effective for annual periods beginning after December 15, 2016, with early adoption allowed.
Apache has elected to adopt the accounting standard for the year ended December 31, 2015 and as a result, all deferred tax assets, liabilities, and related valuation allowances are classified as noncurrent on Apache Corporation’s December 31, 2015 consolidated balance sheet.
Prior consolidated balance sheets were not retrospectively adjusted.
Net deferred tax assets and liabilities are included in the consolidated balance sheet as follows:
## Table 2 ##
In 2015, Apache repatriated the sales proceeds from the divestment of its interest in LNG projects and Australian upstream assets.
Upon the repatriation of these proceeds, Apache recognized a U. S.  current income tax liability of $560 million.
Pursuant to its plan of divestiture of these assets, Apache recorded a deferred income tax liability of $560 million on undistributed foreign earnings in 2014.
In 2014, Apache evaluated its permanent reinvestment position and determined that undistributed earnings from certain foreign subsidiaries located in Apache’s Australia, Egypt, and North Sea regions will no longer be permanently reinvested.
As a result of this change in position, the Company recorded $560 million of U. S.  deferred income tax expense on undistributed earnings that were previously considered permanently reinvested as a component of continuing operations.
In addition, the Company recorded $311 million and $225 million of U. S.  deferred income tax expense on foreign earnings that were distributed to the U. S.  in 2014 and 2013, respectively.
The Company’s Canadian subsidiaries do not currently have undistributed earnings.
In 2015, the U. K.  government enacted Finance Bill 2015 that provides tax relief to E&P companies operating in the North Sea through a reduction of Supplementary Charge from 32 percent to 20 percent, effective January 1, 2015.
As a result of the enacted legislation, in 2015, Apache recorded a deferred tax benefit of $619 million related to the remeasurement of the Company’s December 31, 2014 U. K.  deferred income tax liability.
In 2015, the Company recorded a valuation allowance against the U. S.  region’s net deferred tax asset.
The deferred tax position in the U. S.  changed from a net deferred tax liability as of December 31, 2014 to a net deferred tax asset as of December 31, 2015 as a result of $19.5 billion in non-cash ceiling test write-downs and the recognition of $2.1 billion of deferred tax assets related to foreign tax credit carryforwards.
The Company has assessed the potential realization of its U. S.  net deferred tax asset and has concluded that it is more likely than not that the U. S.  net deferred tax asset will not be realized based on current economic conditions and expectations for the future.
In addition, the Company has recorded an increase in valuation allowance against certain foreign deferred tax assets, primarily driven by non-cash ceiling test write-downs.
The Company has assessed the future potential
