Stock-Based Compensation

STOCK OPTION PLANS

The number of shares authorized for issuance under the Company’s 2005 Stock Incentive Plan, as amended and restated (the “2005 Plan”), is 11,424 shares at June 30, 2015. On October 21, 2014, the Company's number of shares authorized for issuance under the 2005 Plan increased by 3,406 shares, including 3,200 shares approved by the Company's shareholders at the 2014 Annual Meeting of Shareholders and 206 shares as a result of forfeitures, cancellations and/or terminations from the Company's 1997 Stock Option Plan (the "1997 Plan"). The 2005 Plan will be increased by any future cancellations, forfeitures or terminations (other than by exercise) under the 1997 Plan. The 2005 Plan provides for the grant of non-qualified and incentive stock options, restricted stock, stock appreciation rights and deferred stock awards to employees and non-employees. All stock options are granted with an exercise price of not less than 100% of the fair value of the Company’s common stock at the date of grant and the options generally have a term of seven years. There were 3,648 shares available for future grant under the 2005 Plan at June 30, 2015.

The number of shares authorized for issuance under the 1997 Plan was 8,650 shares, of which 100 shares could be issued pursuant to restricted stock grants. The 1997 Plan provided for the grant of non-qualified and incentive stock options and restricted stock to employees and non-employees. All stock options were granted with an exercise price of not less than 100% of the fair value of the Company’s common stock at the date of grant. The options typically vest over periods of zero to four years and have a maximum term of 10 years. Following shareholder approval of the 2005 Plan on November 14, 2005, the Company’s Board of Directors determined that no further grants of stock options or other awards would be made under the 1997 Plan, and the 1997 Plan subsequently expired in June 2007. The foregoing does not affect any outstanding awards under the 1997 Plan, which remain in full force and effect in accordance with their terms.

On August 15, 2014, as part of the Company's ongoing annual equity grant program for employees, the Company granted performance-based restricted stock awards to certain executives pursuant to the 2005 Plan. These performance awards vest annually over a three year requisite service period subject to the achievement of specific financial performance targets related to adjusted EBITDA as a percentage of revenue. Based on the performance targets, these awards require graded vesting that results in more rapid expense recognition compared to traditional time-based vesting over the same vesting period. The Company monitors the probability of achieving the performance targets on a quarterly basis and may adjust periodic compensation expense accordingly.

EMPLOYEE STOCK PURCHASE PLAN

The number of shares authorized for issuance under the Company’s 1997 Employee Stock Purchase Plan, as amended and restated (“ESPP”), is 1,400 shares. Under the ESPP, rights are granted to purchase shares of common stock at 85% of the lesser of the market value of such shares at either the beginning or the end of each six-month offering period. The ESPP permits employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s compensation as defined in the ESPP. The number of shares issued under the ESPP during fiscal years 2015, 2014, and 2013 was 79, 92 and 104, respectively. Shares available for future purchase under the ESPP totaled 85 at June 30, 2015.

STOCK-BASED COMPENSATION EXPENSE AND ASSUMPTIONS

The Company recognized the full expense of its share-based payment plans in the consolidated statements of operations for the fiscal years 2015, 2014, and 2013 in accordance with FASB ASC 718 and did not capitalize any such costs on the consolidated balance sheets, as such costs that qualified for capitalization were not material. Under the fair value recognition provisions of FASB ASC 718, stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the service period. The following table presents share-based compensation expenses from continuing operations included in the Company’s consolidated statement of operations:



	Year Ended June 30,
	2015			2014			2013
Cost of revenues	$	493		$	601		$	371

There were no options granted during fiscal years 2015 or 2014. The only stock options granted during fiscal year 2013 were related to the Micronetics stock option rollover at the acquisition date. The following table sets forth the weighted-average key assumptions and fair value results for stock options granted during fiscal years 2015, 2014 and 2013:



	Years Ended June 30,
	2015			2014			2013
Weighted-average fair value of options granted	$	—		$	—		$	3.80
Option life(1)	—			—			4.5
Risk-free interest rate(2)	—		%	—		%	0.73		%
Stock volatility(3)	—		%	—		%	58		%
Dividend rate	—		%	—		%	—		%


(1)	The option life was determined based upon historical option activity.


(2)	The risk-free interest rate for each grant is equal to the U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life.


(3)	The stock volatility for each grant is measured using the weighted average of historical daily price changes of the Company’s common stock over the most recent period equal to the expected option life of the grant, the historical short-term trend of the option and other factors, such as expected changes in volatility arising from planned changes in the Company’s business operations.
