Stock-Based Compensation

Stock-based compensation expense is included within compensation and benefits in the condensed consolidated income statements and totaled $0.5 million and $0.6 million for the three months ended June 30, 2011 and 2010, respectively and $1.6 million and $1.4 million for the nine months ended June 30, 2011 and 2010, respectively.

Stock Option Plans

The Company sponsors a stock option plan for its directors, officers, employees and consultants. At June 30, 2011, 744,481 shares were authorized for future grant under this plan. Awards that expire or are canceled generally become available for issuance again under the plan. We settle stock option exercises with newly issued shares of common stock.

Fair value is estimated at the grant date based on a Black-Scholes-Merton option-pricing model using the following weighted-average assumptions:

	Nine Months Ended June 30,
	2011		2010
Expected stock price volatility	77	%	85	%
Expected dividend yield	—	%	—	%
Risk free interest rate	0.72	%	1.46	%
Average expected life (in years)	2.94		2.80

Expected stock price volatility rates are based on the historical volatility of the Company’s common stock. The Company has not paid dividends in the past and does not currently expect to do so in the future. Risk free interest rates are based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option or award. The average expected life represents the estimated period of time that options or awards granted are expected to be outstanding, based on the Company’s historical share option exercise experience for similar option grants.
