Stock-Based Compensation [Abstract]

Stock-Based Compensation

Note 6. Stock-Based Compensation

Stock-based compensation is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the requisite service period (generally the vesting period of the grant).

Our net loss for the three month periods ended December 31, 2015 and December 31, 2014 includes $177,000 and $67,000, respectively, of compensation costs related to our stock-based compensation arrangements.

Stock Option awards

The Company measures the compensation cost associated with stock option awards by estimating the fair value of the award as of the grant date using the Black-Scholes pricing model. The Company believes that the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in calculating the fair values of the Company’s stock options and stock awards granted during the three months ended December 31, 2015. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by the employees who receive equity awards.

During the three months ended December 31, 2015, the Company granted a total of 22,686 non-statutory stock options and a total of 54,110 incentive stock options, from available shares under its 2008 Plan, as amended, with exercise prices between of $5.29 and $6.23 and per-share weighted average fair values between $2.87 and $4.52.

In addition to the exercise and grant date prices of the stock option awards, certain weighted average assumptions that were used to estimate the fair value of stock option grants are listed in the following table:

	Fiscal 2016 Incentive Stock Options
Expected term (years)	6.5 to 7.5
Expected volatility	81.77% to 89.08%
Risk-free interest rate	1.65% to 2.07%
Expected dividends	0

We estimate expected volatility based on historical weekly price changes of our common stock for a period equal to the current expected term of the options. The risk-free interest rate is based on the United States treasury yields in effect at the time of grant corresponding with the expected term of the options. The expected option term is the number of years we estimate that options will be outstanding prior to exercise considering vesting schedules and our historical exercise patterns.

The following table summarizes stock option activity for the three month period ended December 31, 2015 under all plans:

		Shares				Weighted Average Exercise Price		Weighted Avg. Remaining Contractual Life (Yrs.)
Outstanding-beginning of year			540,444			$5.27
Options granted			76,796			$5.31
Options exercised			0
Forfeited			(9,628	)		$7.79
Expired			(13,917	)		$17.04
Outstanding December 31, 2015			593,695			$4.96		7.6
Exercisable December 31, 2015			134,670			$4.73		4.5

As of December 31, 2015, the aggregate intrinsic value of the outstanding and exercisable options was $758,000 and $276,000, respectively. Only options whose exercise price is below the current market price of the underlying stock are included in the intrinsic value calculation.

As of December 31, 2015, the total remaining unrecognized compensation cost related to non-vested stock options was $954,000 and is expected to be recognized over a weighted average period of approximately 4.9 years.

There were 3,891 stock options exercised during the three months ended December 31, 2014 with proceeds of $7,000, no stock options were exercised in the three month period ended December 31, 2015.

Restricted Stock Grants

During the three months ended December 31, 2015, the Company granted a total of 44,755 shares of restricted stock to certain employees and executive officers from available shares under its 2008 Plan, as amended. The shares were issued with grant date fair market values of $4.18 which is equal to the closing price of the stock on the date of the grants. The restricted stock grants vest over three years following the grant date.

A summary of the status of non-vested restricted stock as of December 31, 2015 is presented below.

		Shares				Grant Date Fair Value Per Share
Non-vested shares at beg of year			148,426			$3.23 to $8.60
Granted			44,755			$4.18
Forfeited			(8,721	)
Vested			0
Non-vested shares at Dec 31, 2015			184,460

As of December 31, 2015, there was $362,000 of total unrecognized compensation cost related to non-vested restricted stock. This cost is expected to be recognized over a weighted average period of approximately 2.9 years.
