10. Share-Based Employee Compensation

10.           Share-Based Employee Compensation

The Company has employee and non-employee director stock option programs.  Related to these programs, and in accordance with ASC Topic 718, “Compensation-Stock Compensation”, the Company recorded $27, $172 and $281 of share-based employee compensation expense during the years ended December 31, 2012, 2011and 2010, respectively, and is included as a component of cost of products and selling, general and administrative expenses in the accompanying consolidated statements of operations.  No amount of share–based employee compensation expense was capitalized as part of capital expenditures or inventory for the years presented.

The Company uses the Black-Scholes-Merton option valuation model to calculate the fair value of a stock option grant. The share-based employee compensation expense recorded in the years ended December 31, 2012, 2011and 2010 was calculated using the assumptions noted in the following table. Expected volatilities are based on the historical volatility of the Company’s common stock over the period of time commensurate with the expected life of the stock options. While the Company paid a one-time special cash dividend in 2007, it has never paid a cash dividend previously, nor is a cash dividend planned for the future. Accordingly, the assumed dividend yield is zero. The Company has estimated its future stock option exercises. The expected term of option grants is based upon the observed and expected time to the date of post vesting exercises and forfeitures of options by the Company’s employees. The risk-free interest rate is derived from the average U.S. Treasury rate for the period, which approximates the rate at the time of the stock option grant.

	FY 2012			FY 2011			FY 2010
Expected Volatility		72.3	%		86.4	%		76.6% - 83.7	%
Expected Dividends		0.00			0.00			0.00
Expected Term (in years)		3.0			3.0			3.0 - 6.5
Risk-Free Rate		0.40	%		0.90	%		2.54	%
Estimated forfeitures		0.0	%		0.0	%		0.0	%
