Schedule of restricted stock rights activity

The following table summarizes our restricted stock rights activity for the year ended December 31, 2015, with performance-vesting restricted stock right grants presented at the maximum potential shares that could be earned and issued at vesting (amounts in thousands except per share amounts):

	Restricted Stock Rights		Weighted- Average Grant Date Fair Value
Unvested restricted stock rights balance at December 31, 2014	17,967		$	11.85
Granted*	2,330		29.31
Vested	(7,146	)	12.80
Forfeited	(1,221	)	15.23
Unvested restricted stock rights balance at December 31, 2015	11,930		$	12.74

* 1.7 million of the performance-vesting restricted stock rights granted at maximum potential shares did not have an accounting grant date as there is not a mutual understanding between the Company and the employee of the performance terms. Accordingly, no grant date fair value was established and the weighted averaged grant date fair value calculated above excludes these shares.
