For the three months ended March 31, 2013, there were no dilutive stock rights due to the net loss reported for the period. The weighted average diluted common shares outstanding for the three months ended March 31, 2012 excludes the effect of approximately 2,703 weighted average stock rights outstanding because their effect would be anti-dilutive.
