6 Months Ended

Jun. 30, 2016

The following is a reconciliation of the average shares outstanding used to compute basic and diluted earnings per share:



	Three Months Ended June 30,		Six Months Ended June 30,
	2016	2015	2016	2015
Basic weighted average common shares outstanding	137,138,220	136,130,861	136,869,066	135,887,738
Effect of dilutive securities	—	1,855,038	—	1,543,827
Diluted weighted average common shares outstanding	137,138,220	137,985,899	136,869,066	137,431,565

For the three months ended June 30, 2016 and June 30, 2015, 4.2 million and 2.2 million, respectively, of common shares issuable upon the exercise of stock options were anti-dilutive and were excluded from the calculation of diluted shares. For the six months ended June 30, 2016 and June 30, 2015, respectively, 4.2 million and 2.2 million of common shares issuable upon the exercise of stock options were anti-dilutive and were excluded from the calculation of diluted shares.

For the three and six months ended June 30, 2016, the total number of potentially dilutive options was 1.6 million and 1.1 million, respectively. Because the Company had a loss from continuing operations for the quarter, these dilutive options were not included in the computation of diluted net loss per common share since doing so would decrease the loss per share.

No dividends were paid during each of the six months ended June 30, 2016 and June 30, 2015.
