(A) For the years ended December 31, 2014 and 2013 there were no contingently issuable escrow shares outstanding. For the year ended December 31, 2012, 0.7 million contingently issuable escrow shares were excluded from the calculation as their effect would have been anti-dilutive.

(B) The following as-if converted shares associated with the Company’s 2013 and 2015 convertible senior notes were excluded from the calculation as their effect would be anti-dilutive (in thousands):

	For the Years Ended December 31,
	2014	2013	2012
2013 convertible senior notes	—	—	2,450
2015 convertible senior notes	2,110	2,110	1,067
Total as-if converted shares excluded	2,110	2,110	3,517

(C) The following shares, by equity award type, were excluded from the calculation, as their effect would have been anti-dilutive (in thousands):

	For the Years Ended December 31,
	2014	2013	2012
Stock options	2,841	3,465	2,555
Restricted stock units	128	335	527
Performance based restricted stock units (D)	240	193	—
Total equity award shares excluded	3,209	3,993	3,082

(D) Shares under the Long-Term Incentive Plan ("LTIP") are presented based on attainment of 100% of the performance goals being met. The LTIP provides for the grants of awards payable in shares of common stock upon the achievement of performance goals set by the Company's Compensation and Development Committee. In addition to the performance conditions, the awards contain market-based multipliers based on the average price of the Company's common stock thirty days prior to the end of each semi-annual performance period. The maximum multiplier for a given semi-annual performance period is 2.75x the original grant and overall achievement is limited to a maximum of 2.5x of the target award over the entire performance period. Based on this formula, the maximum number of shares that could be earned was 0.6 million and 0.5 million for the years ended December 31, 2014 and 2013.
