Note 3. Share-Based Payments

The Company has in place a 2010 Equity Incentive Plan and a 2008 Equity Incentive Plan. In general, these plans provide for stock-based compensation in the form of (i) Non-statutory Stock Options; (ii) Restricted Stock Awards; and (iii) Stock Appreciation Rights to the Company’s employees, directors and non-employees. The plans also provide for limits on the aggregate number of shares that may be granted, the term of grants and the strike price of option awards.

Stock-based compensation in the amount of $775,000 and $808,000 was recognized for the three months ended July 31, 2015 and 2014, respectively. Stock-based compensation expense was recognized as follows (table in thousands):

Stock Option Grants

Black-Scholes assumptions used to calculate the fair value of options granted during the three months ended July 31, 2015 and 2014 were as follows:

	Three Months Ended
	July 31,
		2015	2014

Expected term in years		5 - 6		2.5 - 6
Risk-free interest rates		1.57% - 1.774%		0.95% - 2.24%
Volatility		87.8% - 92.8%		94.08% - 102.5%
Dividend yield		0%		0%

The weighted average fair value of stock options granted during the three months ended July 31, 2015 and 2014 was $4.85 and $8.28, respectively. The Company’s stock options activity for the three months ended July 31, 2015 is as follows:

									Weighted

	Employees		Employees		Total		Price		Life (Years)		Value

Outstanding, May 1, 2015		57,917		1,946,085		2,004,002	$	5.74		6.7	$	4,166,000

Vested and expected to vest as of July 31, 2015		51,250		1,963,257		2,014,507		5.72		6.6	$	1,457,000

Exercisable as of July 31, 2015		34,271		1,522,517		1,556,788		5.90		6.0	$	1,093,000

Included in the balances outstanding in the table above are 224,663 options (which vest based on service criteria) granted to the Company’s Chief Executive Officer and its President as of November 5, 2013 as part of their new employment agreements. In addition to the above, there are 224,663 additional options granted to the Company’s Chief Executive Officer and President which vest based on both service and performance criteria. The service-based conditions of these options provide for vesting to occur monthly over a period of three years. The service-based options, like all of the Company’s service-based options, are expensed on a straight-line basis. Since the straight-line method is not available for performance or market-based share-based payments, the 224,663 performance-based options will be expensed on an accelerated basis once the Company determines it is probable that the performance-based conditions will be met.
