GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization and Basis of Presentation The interim condensed consolidated financial statements include the accounts of Alaska Air Group, Inc. (Air Group or the Company) and its primary subsidiaries, Alaska Airlines, Inc. (Alaska) and Horizon Air Industries, Inc. (Horizon), through which the Company conducts substantially all of its operations. All intercompany balances and transactions have been eliminated. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. Consistent with these requirements, this Form 10-Q does not include all the information required by GAAP for complete financial statements. As a result, this Form 10-Q should be read in conjunction with the Consolidated Financial Statements and accompanying Notes in the Form 10-K for the year ended December 31, 2015. In the opinion of management, all adjustments have been made that are necessary to present fairly the Company’s financial position as of September 30, 2016, as well as the results of operations for the three and nine months ended September 30, 2016 and 2015. The adjustments made were of a normal recurring nature. In preparing these statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities, as well as the reported amounts of revenues and expenses. Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices, changes in global economic conditions, changes in the competitive environment, and other factors, operating results for the three and nine months ended September 30, 2016 are not necessarily indicative of operating results for the entire year. Certain reclassifications have been made to prior year financial statements to conform with classifications used in the current year. Recently Issued Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update 2014-09, "Revenue from Contracts with Customers" (ASU 2014-09), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In March 2016, the FASB issued ASU 2016-08, "Revenue from Contracts with Customers" (Topic 606), Principal versus Agent Considerations, which provides guidance when a revenue transaction involves a third party in providing goods or services to a customer in determining whether the Company is considered the principal or the agent in the transaction. Entities are permitted to use either a full retrospective or cumulative effect transition method, and are required to adopt all parts of the new revenue standard using the same transition method. The new standard is effective for the Company on January 1, 2018. At this time, the Company believes the most significant impact to the financial statements will be in Mileage Plan revenues and liabilities. The Company currently uses the incremental cost approach for miles earned through travel. This standard eliminates that option and the Company will be required to increase its liability for earned miles through a relative selling price model. The Company continues to evaluate the full impact of the standard, and currently plans to apply the full retrospective transition method. In April 2015, the FASB issued ASU 2015-03, "Interest - Imputation of Interest" (Subtopic 835-30), which requires debt issuance costs related to a debt liability be presented as a direct deduction from the carrying value of the debt liability. The amendment was adopted as of January 1, 2016. Prior period debt balances have been adjusted to reflect the adoption of ASU 2015-03. The adoption of the ASU had no impact on the Statements of Operations or retained earnings. In February 2016, the FASB issued ASU 2016-02, "Leases" (Topic 842), which requires lessees to recognize assets and liabilities for leases currently classified as operating leases. Under the new standard a lessee will recognize a liability on the balance sheet representing the lease payments owed, and a right-of-use-asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities. The new standard is effective for the Company on January 1, 2019. Early adoption of the standard is permitted. The Company is evaluating the effect that ASU 2016-02 will have on its financial statements and related disclosures. The Company has not yet determined whether it will early adopt the standard. In March 2016, the FASB issued ASU 2016-09, "Compensation - Stock Compensation" (Topic 718). The proposed standard simplifies several aspects of accounting for employee share-based payment awards, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company is evaluating the effect of ASU 2016-09 on the consolidated financial statements and related disclosures. The ASU is effective for the Company beginning January 1, 2017. The Company has not yet elected a transition method.
