Stock Compensation

4. Stock Compensation

Stock-based compensation expense is computed using the fair value of stock-based awards measured at the grant date, recognized over the relevant service period, and is adjusted each period for anticipated forfeitures. The grant date fair value of stock option awards is estimated using the Black-Scholes option pricing model, assuming no expected dividends and the following weighted average assumptions:

	Three months  ended December 31,						Six months ended December  31,
	2012			2011			2012			2011
Expected volatility (based on historical data)		33.9	%		30.5	%		33.7	%		29.7	%
Expected life in years		4.0			4.75			4.0			4.75
Risk-free interest rate		0.70	%		0.83	%		0.70	%		1.00	%
Fair value per award	$	2.47		$	1.69		$	2.43		$	1.76

Stock-based compensation expense reflects non-cash compensation expense associated with restricted stock purchase rights and employee stock options. Stock-based compensation expense is included in costs and expenses as follows:

	Three months  ended December 31,				Six months ended December  31,
	2012		2011		2012		2011
Cost of service and other revenues	$	20	$	15	$	39	$	29

Research and development		101		75		216		149
General and administrative		186		229		366		453
Total	$	481	$	467	$	984	$	912

As of December 31, 2012, $4.1 million of unrecognized compensation costs related to non-vested awards is expected to be recognized over a weighted average period of approximately 2.0 years.
