Basic	$	2.30	$	2.72
Stock options to purchase 19,129 shares were outstanding as of March 31, 2014, but were not included in the
computation of diluted earnings per share because the options' exercise price during the period was greater than the average
market price of the common shares, and, therefore, the effect would have been antidilutive. There were no stock options
outstanding as of March 31, 2013 that were considered antidilutive.
