Earnings (Loss) per Share

We include restricted stock units for which no future service is required as a condition to the delivery of the underlying common stock in our calculation of weighted average shares outstanding. As we incurred a net loss for each of the three and six months ended June 30, 2013, diluted loss per share for both periods are computed on the same basis as basic loss per share, as the inclusion of any other potential shares outstanding would be anti-dilutive. Reconciliations of the amounts used in the basic and diluted earnings (loss) per common share computations for the three and six months ended June 30, 2014 and 2013, are as follows (shares in thousands):



	Three Months Ended June 30,		Six Months Ended June 30,
	2014	2013	2014	2013
Diluted weighted average shares calculation:
Weighted average shares outstanding (basic)	416,507	447,558	418,296	449,620
Share-based awards	4,841	—	4,401	—
Weighted average shares outstanding (diluted)	421,348	447,558	422,697	449,620

We excluded the following items from diluted earnings (loss) per common share for the three and six months ended June 30, 2014 and 2013, because they were anti-dilutive (shares in thousands):

	2014	2013	2014	2013
