Income Tax Disclosure [Abstract]  
Schedule of Components of Income Tax Expense (Benefit)
The Company’s tax provision and the resulting effective tax rate for interim periods is determined based upon its estimated annual effective tax rate, adjusted for the effect of discrete items arising in that quarter. When applicable, the Company also excludes jurisdictions with a projected loss for the year (or year-to-date loss) where the Company cannot or does not expect to recognize a tax benefit from its estimated annual effective tax rate. The impact of such inclusions could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings or losses versus annual projections. In each quarter, the Company updates its estimate of the annual effective tax rate, and if the estimated annual tax rate changes, a cumulative adjustment is made in that quarter.
