⁽¹⁾ Options to purchase 89,617 and 226,098 shares of Company common stock were excluded from the computations of diluted earnings per share for the three months ended March 31, 2016 and March 31, 2015, respectively. The options’ exercise prices were greater than the average market price for the common stock, and the effect of including the options would have been antidilutive.
