STOCKHOLDERS’ EQUITY

Stock Award Activity

Common shares outstanding plus shares underlying outstanding stock awards totaled 483 million as of March 31, 2015, and December 31, 2014. These totals include all vested and unvested stock awards outstanding, including those awards we estimate will be forfeited. The compensation expense for stock options, the total intrinsic value for stock options outstanding, the amount of cash received from the exercise of stock options, and the related tax benefits were not material for the three months ended March 31, 2015.

The following table summarizes our restricted stock unit activity for the three months ended March 31, 2015 (in millions):

	Number of Units		Weighted Average Grant-Date Fair Value
Outstanding as of December 31, 2014	17.4		$	285

Units vested	(0.8	)	216
Units forfeited	(0.6	)	289
Outstanding as of March 31, 2015	17.4		$	294

Scheduled vesting for outstanding restricted stock units as of March 31, 2015, is as follows (in millions):

	Nine Months Ended December 31,	Year Ended December 31,

Scheduled vesting—restricted stock units	4.9	6.0	3.7	2.1	0.5	0.2	17.4

As of March 31, 2015, there was $2.2 billion of net unrecognized compensation cost related to unvested stock-based compensation arrangements. This compensation is recognized on an accelerated basis with approximately half of the compensation expected to be expensed in the next twelve months, and has a weighted average recognition period of 1.1 years.
