Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements include the accounts of PHI, Inc. and its subsidiaries (“PHI” or the “Company” or “we” or “our”). In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting of only normal, recurring adjustments, necessary to present fairly the financial results for the interim periods presented. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 and the accompanying notes. Our financial results, particularly as they relate to our Oil and Gas segment, are influenced by seasonal fluctuations as discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. For this and other reasons, the results of operations for interim periods are not necessarily indicative of the operating results that may be expected for a full fiscal year. New Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. In mid-2015 the FASB deferred the effective date of ASU 2014-09 by one year until annual and interim periods beginning after December 15, 2017. Early adoption will be permitted as of January 1, 2017; however we have not yet determined if we will adopt this ASU prior to the effective date. The effects of this standard on our financial position, results of operations and cash flows are not yet known. In August 2014, the FASB issued ASU 2014-15 Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 requires management to assess the entity’s ability to continue as a going concern and to provide related disclosures in certain circumstances. ASU 2014-15 is effective for annual and interim periods beginning after December 15, 2016. We do not believe that the impact of the implementation of this new guidance on our consolidated financial statements and disclosures will be significant. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, which amends existing guidance on income taxes to require the classification of all deferred tax assets and liabilities as non-current on the balance sheet. We are required to adopt this ASU no later than January 1, 2018, with early adoption permitted, and the guidance may be applied either prospectively or retrospectively. We do not expect this ASU to have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases, which replaces the existing guidance on leasing transactions in ASC 840 to require recognition of the assets and liabilities for the rights and obligations created by those leases on the balance sheet. We are required to adopt this ASU for fiscal years after December 31, 2018, with early adoption permitted. The effects of this standard on our financial position, results of operations, and cash flows are not yet known. In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718); Improvements to Employee Share-Based Payment Accounting. The ASU includes multiple provisions intended to simplify various aspects of the accounting for share-based payments. The ASU is effective for public companies in annual periods beginning after December 15, 2016, and interim periods within those years. The effects of this standard on our financial position, results of operations, and cash flows are not yet known.
