New Accounting Standards [Abstract]
New Accounting Standards	3.NEW ACCOUNTING STANDARDS Revenue From Contracts With Customers. In May 2014, the Financial Accounting Standards Board (the “FASB”) issued guidance to provide a single, comprehensive revenue recognition model for all contracts with customers. The revenue guidance contains principles that an entity will apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The standard will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017 for public entities, with early adoption permitted (but not earlier than the original effective date of the pronouncement). The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures, but based on its evaluation to date, the Company does not expect the adoption of this accounting standard to have a material impact on its financial statements. Balance Sheet Classification of Deferred Taxes. In November 2015, the FASB issued guidance that requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. As a result, each jurisdiction will now only have one net noncurrent deferred tax asset or liability. The guidance does not change the existing requirement that only permits offsetting within a jurisdiction. The new standard is effective in fiscal years beginning after December 15, 2016, including interim periods within those years. The Company adopted this guidance as of January 1, 2017, which resulted in the Company’s current deferred tax assets being recorded as noncurrent on a retrospective basis. The Company’s current deferred tax assets were $64,950 and $89,177 at March 31, 2017 and December 31, 2016, respectively. Lease Accounting. In February 2016, the FASB issued guidance that requires lessees to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Operating leases will result in straight-line expense (similar to current operating leases) while finance leases will result in a front-loaded expense pattern (similar to current capital leases). Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit bright lines. The new standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The new standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. The Company has not yet assessed the potential impact of implementing this new accounting standard on its consolidated financial statements. Improvements to Employee Share-Based Payment Accounting. In March 2016, the FASB issued guidance that identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including classification of awards as either equity or liabilities, an option to recognize gross share compensation expense with actual forfeitures recognized as they occur, certain classifications on the statement of cash flows and income tax consequences, including that all income tax effects of awards are to be recognized in the income statement when the awards are settled whereas previously the tax benefits in excess of compensation cost were recorded in equity. The new standard is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. As such, the Company adopted this standard on January 1, 2017 and classified the excess tax benefits associated with equity-based compensation arrangements, which were $6,719 during the three months ended March 31, 2017, as a discrete item within Income tax provision (benefit) on the Condensed Consolidated Statements of Net Income, rather than recognizing such excess income tax benefits in Additional Paid-In Capital on the Condensed Consolidated Statements of Equity. This reclassification was made on a prospective basis and also impacted the related classification on the Company’s Condensed Consolidated Statements of Cash Flows as excess tax benefits associated with equity-based compensation arrangements were previously reported in cash flows from operating activities and cash flows from financing activities. Under the new standard, excess tax benefits associated with equity-based compensation are only reported in cash flows from operating activities. Additionally, the Company now recognizes gross share compensation expense with actual forfeitures as they occur, which differs from the Company’s previous accounting policy to estimate forfeitures each period. Using the modified retrospective approach, the Company recorded a cumulative effect adjustment to Retained Earnings of $1,384 for the differential between the amount of compensation cost previously recorded and the amount that would have been recorded without assuming forfeitures. Principal versus Agent Considerations (Reporting Revenue Gross versus Net). In March 2016, the FASB issued guidance that clarifies the implementation of the new revenue standard on principal versus agent considerations. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to the customers. The amendments have the same effective date and transition requirements as the new revenue standard, which is described above. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures, but based on its evaluation to date, the Company does not expect the adoption of this accounting standard to have a material impact on its financial statements. Classification of Certain Cash Receipts and Cash Payments. In August 2016, the FASB issued guidance that addresses eight targeted changes with respect to how cash receipts and cash payments are classified in the statements of cash flows, with the objective of reducing diversity in practice. The new standard is effective for public companies for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, provided that all of the amendments are adopted in the same period. The guidance requires application using a retrospective transition method. The Company does not expect the adoption of this guidance to have a material impact on the Company’s statement of cash flows. Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory. In October 2016, the FASB issued guidance that eliminates the exception for all intra-entity sales of assets other than inventory. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buyer’s jurisdiction would also be recognized at the time of the transfer. The modified retrospective approach will be required for transition to the new guidance, with a cumulative-effect adjustment recorded in retained earnings as of the beginning of the period of adoption. The new guidance will be effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those years. Early adoption is permitted; however, the guidance can only be adopted in the first interim period of a fiscal year. The Company does not expect the adoption of this guidance to have a material impact on the consolidated financial statements. Statement of Cash Flows: Restricted Cash. In November 2016, the FASB issued guidance that requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Entities will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. The new standard is effective for public companies for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The Company does not expect the adoption of this guidance to have a material impact on the Company’s statement of cash flows. Simplifying the Test for Goodwill Impairment. In January 2017, the FASB issued guidance that simplifies the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. The new standard will be applied prospectively, and is effective for public companies for their annual or any interim goodwill impairment tests for fiscal years beginning after December 15, 2019. Early adoption is permitted for any impairment tests performed after January 1, 2017. The Company early adopted this new guidance on January 1, 2017. During the year ended December 31, 2016, the Company did not record any impairment charges related to goodwill; however, the results of the Company’s annual impairment testing indicated that the carrying value of its E&P segment exceeded its fair value by more than $77,343, which was the carrying value of goodwill at its E&P segment at December 31, 2016. Upon adopting this accounting guidance in the first quarter of 2017, the Company performed an updated impairment test for its E&P segment which showed its carrying value continued to exceed its fair value by an amount in excess of the carrying amount of goodwill, or $77,343. Therefore, the Company recorded an impairment charge of $77,343, consisting of the carrying amount of goodwill at its E&P segment at January 1, 2017, to Impairments and other operating charges in the Condensed Consolidated Statements of Net Income during the three months ended March 31, 2017.

Statement of Cash Flows: Restricted Cash. In November 2016, the FASB issued guidance that requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Entities will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions.

Early adoption is permitted for any impairment tests performed after January 1, 2017. The Company early adopted this new guidance on January 1, 2017. During the year ended December 31, 2016, the Company did not record any impairment charges related to goodwill; however, the results of the Company’s annual impairment testing indicated that the carrying value of its E&P segment exceeded its fair value by more than $77,343, which was the carrying value of goodwill at its E&P segment at December 31, 2016. Upon adopting this accounting guidance in the first quarter of 2017, the Company performed an updated impairment test for its E&P segment which showed its carrying value continued to exceed its fair value by an amount in excess of the carrying amount of goodwill, or $77,343. Therefore, the Company recorded an impairment charge of $77,343, consisting of the carrying amount of goodwill at its E&P segment at January 1, 2017, to Impairments and other operating charges in the Condensed Consolidated Statements of Net Income during the three months ended March 31, 2017.
