Weighed-Average Key Assumptions and Fair Value Results for Stock Options Granted

There were no options granted during fiscal year 2012. The following table sets forth the weighted-average key assumptions and fair value results for stock options granted during fiscal years 2011 and 2010:

	Years Ended June 30,
	2012		2011		2010
Weighted-average fair value of options granted	$	—	$	7.25	$	7.17
Option life(1)		—		5.0 years		5.0 years
Risk-free interest rate(2)		—		1.27%		2.38%
Stock volatility(3)		—		63%		87%
Dividend rate		—		0%		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.
