|Income Tax Disclosure [Abstract]|
We are subject to U.S. federal income tax as well as income tax in multiple state and local jurisdictions. We have concluded all U.S. federal income tax matters as well as material state and local tax matters for years through 2013.
The Tax Cuts and Jobs Act (the "Tax Act") was signed into law on December 22, 2017. The Tax Act significantly affects the U.S. corporate income tax by, among other things, lowering the statutory corporate tax rate from 35% to 21%, eliminating certain deductions, imposing a mandatory one-time tax on accumulated earnings of foreign subsidiaries, and changing how foreign earnings are subject to U.S. tax. The Tax Act also enhanced and extended through 2026 the option to claim accelerated depreciation deductions on qualified property. We have not completed our determination of the accounting implications of the Tax Act on our tax accruals. However, we have reasonably estimated the effects of the Tax Act and recorded provisional amounts in our financial statements as of December 31, 2017. We recorded a provisional tax benefit for the impact of the Tax Act of approximately $10.6 million. This amount is primarily comprised of the re-measurement of our federal net deferred tax liabilities resulting from the permanent reduction in the U.S. corporate tax rate from 35% to 21%. As we complete our analysis of the Tax Act, collect and prepare necessary data, and interpret any additional guidance issued by the U.S. Treasury Department, the Internal Revenue Service, and other standard-setting bodies, we may make adjustments to the provisional amounts. Those adjustments, if any, are not expected to have a material impact on our consolidated financial statements.
We file consolidated federal income tax returns that include all of our subsidiaries. The components of the provision for income taxes from continuing operations for the years ended December 31, 2017, 2016 and 2015 are as follows (in thousands):
