Accounting Policies [Abstract] |
Organization and Basis of Presentation | Organization and Basis of Presentation The condensed consolidated financial statements include the accounts of Air Group, or the Company, and its primary subsidiaries, Alaska (including Virgin America) and Horizon. Our condensed consolidated financial statements also include McGee Air Services, a ground services subsidiary of Alaska. The Company conducts substantially all of its operations through these subsidiaries. All significant 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. It should be read in conjunction with the consolidated financial statements and accompanying notes in the Form 10-K for the year ended December 31, 2017. In the opinion of management, all adjustments have been made that are necessary to fairly present the Company’s financial position as of June 30, 2018 and the results of operations for the three and six months ended June 30, 2018 and 2017. Such adjustments were of a normal recurring nature. Certain reclassifications have been made to prior year financial statements to conform to classifications used in the current year. 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 six months ended June 30, 2018 are not necessarily indicative of operating results for the entire year.
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements 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. In July 2018, the FASB issued ASU 2018-11, "Targeted Improvements - Leases (Topic 842)" which amended Topic 842 to provide companies an alternative transition method which would not require adjusting comparative period financial information. The Company plans to utilize this alternative transition method. The new standard is effective for the Company on January 1, 2019. The Company will not early adopt the standard. At this time, the Company believes the most significant impact to the financial statements will relate to the recording of a right-of-use-asset and related liability associated with leased aircraft. The Company does not expect the new standard to have a material impact on the pattern or amount of expense recognized for aircraft leases on the income statement. Other leases, including airports and real estate, equipment, software and other miscellaneous leases continue to be assessed. In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows—Restricted Cash (Topic 230)" related to the presentation of restricted cash on the statement of cash flows, and within the accompanying footnotes. The Company adopted the standard effective January 1, 2018. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." The ASU expands the activities that qualify for hedge accounting and simplifies the rules for reporting hedging relationships. The ASU is effective for the Company beginning January 1, 2019. The Company will not early adopt the standard. In February 2018, the FASB issued ASU 2018-02, "Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." The standard allows a reclassification from accumulated other comprehensive income (AOCI) to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amount of the reclassification is the difference between the amount initially recorded directly to other comprehensive income at the previously enacted U.S. federal corporate income tax rate that remains in AOCI and the amount that would have been recorded directly to other comprehensive income using the newly enacted U.S. federal income tax rate. The standard is effective for interim and annual reporting periods beginning after December 15, 2018, and early adoption is permitted. The Company elected to early adopt the standard effective January 1, 2018. As a result, retained earnings increased approximately $62 million in 2018 due to the reclassification of tax effects in AOCI recorded in prior periods at previously enacted tax rates.
