The following table sets forth the weighted-average key fair value results and assumptions for stock options granted during the three and nine months ended March 31, 2013 and 2012:

	Three Months Ended March 31,						Nine Months Ended March 31,
	2013			2012			2013			2012
Weighted-average fair value of options granted		—  (	*)		—  (	*)		3.80			—  (*	)

Stock volatility(3)		—  (	*)		—  (	*)		58	%		—  (*	)
Dividend rate		—  (	*)		—  (	*)		0	%		—  (*	)

(1) The option life was determined based upon historical option activity.

(2) The risk-free interest rate for each grant is equal to the U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life.

(3) The stock volatility for each grant is measured using the weighted average of historical daily price changes of the Company’s common stock over the most recent period equal to the expected option life of the grant, the historical short-term trend of the option and other factors, such as expected changes in volatility arising from planned changes in the Company’s business operations.

(*) No stock options were granted by the Company during these periods.
