During the six months ended June 30, 2013 and 2012, 176,689 and 175,321 shares of restricted stock, respectively, were surrendered by employees to satisfy the employees' tax withholding obligations related to the vesting of the stock awards.

2009 Employee Stock Purchase Plan ("ESPP")

During the six months ended June 30, 2013, 20,170 shares were issued under the ESPP, at a purchase price of $7.11 per share. During the six months ended June 30, 2012, 19,823 shares were issued under the ESPP, at a purchase price of $7.00 per share.

The fair value of ESPP rights have been estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:



	Six Months Ended June 30,
	2013	2012
	ESPP Rights	ESPP Rights
Expected term	6 months	6 months
Risk-free rate	0.11%	0.15%
Expected volatility	19.9%	29.4%
Dividend yield	—%	—%

Expected volatility is based on the historical volatility of the market price of the Company’s stock. The expected lives of options granted are based on analysis of historical employee termination rates and option exercises. The risk-free interest rates are based on the expected option lives and the corresponding U.S. treasury yields in effect at the time of grant. The fair value for ESPP rights includes the option exercise price discount from market value provided for under the ESPP.

During the three months ended June 30, 2013 and 2012, the Company recorded $20,000 and $19,000, respectively, of compensation expense related to options and ESPP rights. During the six months ended June 30, 2013 and 2012, the Company recorded $38,000 and $12,000, respectively, of compensation expense related to options and ESPP rights. The weighted average grant-date fair value of ESPP rights arising from elections made by ESPP participants was $1.98 and $1.93 during the six months ended June 30, 2013 and 2012, respectively. The fair value of ESPP rights that vested during the six months ended June 30, 2013 and 2012 was $29,000 and $46,000, respectively.

The intrinsic value of shares purchased through the 2009 ESPP during the six months ended June 30, 2013 was $29,000. The intrinsic value of outstanding 2009 ESPP rights as of June 30, 2013 was $34,000. The intrinsic value of the shares of 2009 ESPP rights is calculated as the discount from the quoted price of the Company’s common stock, as defined in the 2009 ESPP, which was available to employees as of the respective dates.

As of June 30, 2013, there was approximately $7,000 of unrecognized compensation cost related to 2009 ESPP rights, which is expected to be recognized over a period of one month.

The Company received cash from the exercise of options and ESPP rights of $341,000 and $144,000 for the six months ended June 30, 2013 and 2012, respectively, for which the Company issued new shares of common stock.
