       Stock options to purchase 48,202 shares and 19,129 shares were outstanding as of March 31, 2015 and 2014, respectively, 

but were not included in the computation of diluted earnings per share because the options' exercise price during the

respective periods was greater than the average market price of the common shares, and therefore, the effect would have been

antidilutive.
