3. Net Earnings Per Share

Basic earnings per share has been calculated by dividing net earnings by the weighted average number of common shares outstanding during each period. For purposes of calculating diluted earnings per share, shares issuable under employee and director stock options were considered potential common shares and were included in the weighted average common shares unless they were anti-dilutive.

The computation of basic and diluted earnings per common share is as follows:

	Three Months Ended September 30,				Six Months Ended September 30,
	2013		2012		2013		2012
Net earnings	$	456,110	$	227,432	$	594,621	$	644,445
Earnings Per Share:
Basic	$	0.19	$	0.09	$	0.24	$	0.26
Diluted	$	0.18	$	0.09	$	0.24	$	0.26
Weighted Average Shares Outstanding:
Basic		2,446,286		2,446,286		2,446,286		2,446,286
Diluted		2,485,246		2,450,165		2,477,047		2,454,162

For the three months ended September 30, 2013 and 2012, respectively, options to acquire 11,000 and 33,500 shares of common stock, and for the six months ended September 30, 2013 and 2012, respectively, options to acquire 23,500 and 31,000 shares of common stock, were not included in computing diluted earnings per common share because their effects were anti-dilutive.
