Note 2. Stock Based Compensation

The Company has three stock equity plans: The 1997 Employee Stock Option Plan, the 2000 Stock Option Plan and the 2007 Equity Incentive Plan. As of September 26, 2014, no additional awards may be issued under either the 1997 Employee Stock Option Plan or the 2000 Stock Option Plan. There are 2,500,000 shares authorized for issuance under the 2007 Equity Incentive Plan, with 262,095 shares remaining available for future grant.

Options and restricted stock awards may be granted to employees, officers, directors and consultants. Options typically vest over a period of one to four years and are exercisable up to ten years from the date of issuance. The option exercise price equals the stock’s market price on the date of grant. Restricted stock awards typically vest over a period of six months to four years, and the shares subject to such awards are generally not transferrable until the awards vest.

The following table summarizes information regarding options outstanding and options exercisable at each of the quarterly periods through the six months ended September 27, 2013 and September 26, 2014, respectively, and the changes during the periods then ended:

The Company estimates the fair value of stock-based awards utilizing the Black-Scholes pricing model for stock options and using the intrinsic value for restricted stock. The fair value of the awards is amortized as compensation expense on a straight-line basis over the requisite service period of the award, which is generally the vesting period. The Black-Scholes fair value calculations involve significant judgments, assumptions, estimates and complexities that impact the amount of compensation expense to be recorded in current and future periods. The factors include:

1.	The time period that option awards are expected to remain outstanding has been determined based on the average of the original award period and the remaining vesting period. The expected term assumption for awards issued during the six month periods ended September 26, 2014 and September 27, 2013 was 6.3 years.
2.	The future volatility of the Company’s stock has been estimated based on the weekly stock price during the expected term to the date of the latest stock option grant. The expected volatility assumption for awards issued during the six month periods ended September 26, 2014 and September 27, 2013 both averaged 68%.
3.	A dividend yield of zero has been assumed for awards issued during six month periods ended September 26, 2014 and September 27, 2013, based on the Company’s actual past experience and the fact that Company does not anticipate paying a dividend on its shares in the near future.
4.	The Company has based its risk-free interest rate assumption for awards issued during the six month periods ended September 26, 2014 and September 27, 2013 on the implied yield available on U.S. Treasury issues with an equivalent expected term, which both averaged 1.1% during each of the respective periods.
5.	The forfeiture rate, for awards issued during the six month periods ended September 26, 2014 and September 27, 2013, was 26% and 22%, respectively, and was based on the Company’s actual historical forfeiture history.

The Company’s stock-based compensation expense is classified in the table below:

	Three months ended				Six months ended
	September 26, 2014		September 27, 2013		September 26, 2014		September 27, 2013
Cost of Products Sold	$	2,000	$	2,000	$	3,000	$	4,000
Research, development & engineering expense		3,000		7,000		7,000		12,000
General and Administrative expense		10,000		24,000		23,000		39,000
Sales and Marketing expense		1,000		8,000		4,000		15,000
Total Stock Based Compensation	$	16,000	$	41,000	$	37,000	$	70,000

At September 26, 2014, the total stock-based compensation expense related to unvested stock options and restricted shares granted to employees and independent directors under the Company’s stock option plans but not yet recognized was $49,000. This expense will be amortized on a straight-line basis over a weighted-average period of approximately 0.9 years and will be adjusted for subsequent changes in estimated forfeitures.
