Income Tax Disclosure [Abstract] |
Income Taxes | (10) Income Taxes The Company’s effective income tax rate was 17.6% and 38.7% for the three months ended March 31, 2018 and 2017, respectively. The Company’s effective income tax rate for the three months ended March 31, 2018 varied from the U.S. statutory rate of 21% primarily due to the benefit of uncertain tax positions coupled with a favorable tax impact associated with previously acquired tax attributes. The Company recognized the income tax effects of the “Tax Cuts and Jobs Act” (TCJA) in its audited consolidated financial statements on our 2017 Annual Report on Form 10-K in accordance with Staff Accounting Bulletin No. 118, which provides Securities and Exchange Commission staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in which the TCJA was signed into law. The guidance also provides for a measurement period of up to one year from the enactment date for the Company to complete the accounting for the U.S. tax law changes. As such, the Company’s 2017 financial results reflected the provisional estimate of the income tax effects of the TCJA. No subsequent adjustments have been made to the amounts recorded as of December 31, 2017, which continue to represent a provisional estimate of the impact of TCJA. Accordingly, there is no impact to the March 31, 2018 effective tax rate for such provisional amounts. The estimate of the impact of TCJA is based on certain assumptions and the Company's current interpretation, and may change, as the Company receives additional clarification and implementation guidance and as the interpretation of the TCJA evolves over time. TCJA made broad and complex changes to the U.S. tax code, including a new tax law that may subject the Company to a tax on global intangible low-taxed income (“GILTI”) beginning in 2018. GILTI is a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. Companies subject to GILTI have the option to account for the GILTI tax as a period cost if and when incurred, or to recognize deferred taxes for temporary differences including outside basis differences expected to reverse as GILTI. We have not yet determined our policy election with respect to whether to record deferred taxes for basis differences expected to reverse as a result of the GILTI provisions in future periods or use the period cost method. We have, however, included an estimate of the current GILTI impact in our tax provision for 2018.
