Equity [Abstract]

Accumulated Other Comprehensive Loss Primarily Comprised of Accumulated Foreign Currency Translation Adjustments

Accumulated other comprehensive loss is primarily comprised of accumulated foreign currency translation adjustments, as follows for the periods presented:

	December 31, 2019			December 31, 2018
	(in millions)
Cumulative foreign currency translation    Adjustments, net of tax (1)	$	(63	)	$	(62	)
Total accumulated other comprehensive loss (2)	$	(63	)	$	(62	)

(1) Through the year ended December 31, 2018, foreign currency translation adjustments excluded a provision for U.S. federal and state income taxes as a result of the Company's intention to indefinitely reinvest the earnings of its international subsidiaries outside of the United States. In response to increased cash requirements in the U.S. related to the Company’s declaration of a special cash dividend and other strategic initiatives during the fourth quarter of 2019, we determined that we no longer consider certain foreign earnings to be indefinitely reinvested. The deferred income tax liability related to foreign currency translation adjustments is not material.

(2) Our accumulated net unrealized gain (loss) on available for sale debt securities was not material as of December 31, 2018.
