Weighted average common shares outstanding for purposes of computing diluted earnings per share	68,414	67,505	67,255	67,383

Options to purchase approximately 2,000 and 16,000 shares of common stock and 552,000 and 0 restricted stock units were excluded from the computation of diluted earnings per share attributable to common stockholders for the three months ended March 31, 2015 and 2014, respectively, as their effect would be anti-dilutive. In addition, options to purchase approximately 16,000 shares of common stock and 0 shares of restricted stock were excluded from the computation of diluted earnings per share attributable to common stockholders for the six months ended March 31, 2014, as their effect would be anti-dilutive.
