As of March, 31, 2016, there are no shares available for future grants under the 1996 Plan. The 1996 Plan provided for granting incentive stock options to employees and nonstatutory stock options to employees, directors or consultants. The stock option price of incentive stock options granted could not be less than the determined fair market value at the date of grant. Options generally vested over four years and had a ten-year term. 1996 Director Option Plan The Company's 1996 Director Option Plan ("Director Plan") was adopted in June 1996 and became effective in July 1997. A total of 1,650,000 shares of common stock were reserved for issuance under the Director Plan prior to its expiration in June 2006. As of March 31, 2016 there are no shares available for future grants under the Director Plan. The Director Plan provided for both discretionary and periodic grants of nonstatutory stock options to non-employee directors of the Company (the "Outside Directors"). The exercise price per share of all options granted under the Director Plan was equal to the fair market value of a share of the Company's common stock on the date of grant. Options generally vested over a period of four years. Options granted to Outside Directors under the Director Plan had a ten year term, or shorter upon termination of an Outside Director's status as a director. 2006 Stock Plan In May 2006, the Company's board of directors approved the 2006 Stock Plan ("2006 Plan").

The Company reserved 7,000,000 shares of the Company's common stock for issuance under this plan. As of March 31, 2016, 1,238 shares remained available for future grants under the 2006 Plan.

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the aggregate difference between the closing stock price of the Company's common stock on March 31, 2016 and the exercise price for in-the-money options) that would have been received by the option holders if all in-the-money options had been exercised on March 31, 2016. The total intrinsic value of options exercised in the years ended March 31, 2016, 2015 and 2014 was $9.2 million, $8.1 million and $8.2 million, respectively. As of March 31, 2016, there was $34.8 million of unamortized stock-based compensation expense related to unvested stock options and awards which is expected to be recognized over a weighted average period of 2.59 years. Unamortized stock-based compensation expense related to shares issued as part of the DXI acquisition (see Note 13) was approximately $1.8 million, which will be recognized over a weighted average period of 3.17 years. Cash received from option exercises and purchases of shares under the Equity Compensation Plans for the years ended March 31, 2016, 2015 and 2014 were $4.8 million, $4.5 million and $5.2 million, respectively. The total tax benefit attributable to stock options exercised in the year ended March 31, 2016, 2015 and 2014 was $224,000, $151,000 and $142,000, respectively. 1996 Employee Stock Purchase Plan The Company's 1996 Stock Purchase Plan ("Employee Stock Purchase Plan") was adopted in June 1996 and became effective upon the closing of the Company's initial public offering in July 1997. The Company suspended the Employee Stock Purchase Plan in 2003 and reactivated the Employee Stock Purchase Plan in fiscal 2005. Under the Employee Stock Purchase Plan, 500,000 shares of common stock were initially reserved for issuance. At the start of each fiscal year, the number of shares of common stock subject to the Employee Stock Purchase Plan increases so that 500,000 shares remain available for issuance. During fiscal 2016, 2015 and 2014, 365,555, 282,062 and 301,303 shares, respectively, were issued under the Employee Stock Purchase Plan. In May 2006, the Company's board of directors approved a ten-year extension of the Employee Stock Purchase Plan. Stockholders approved a ten-year extension of the Employee Stock Purchase Plan at the 2006 Annual Meeting of Stockholders held September 18, 2006. The Employee Stock Purchase Plan is effective until August 2017. The Employee Stock Purchase Plan permits eligible employees to purchase common stock through payroll deductions at a price equal to 85% of the fair market value of the common stock at the beginning of each two year offering period or the end of a six month purchase period, whichever is lower. When the Employee Stock Purchase Plan was reinstated in fiscal 2005, the offering period was reduced from two years to one year. The contribution amount may not exceed ten percent of an employee's base compensation, including commissions, but not including bonuses and overtime. In the event of a merger of the Company with or into another corporation or the sale of all or substantially all of the assets of the Company, the Employee Stock Purchase Plan provides that a new exercise date will be set for each option under the plan which exercise date will occur before the date of the merger or asset sale. Assumptions Used to Calculate Stock-Based Compensation Expense The fair value of each of the Company's option grants has been estimated on the date of grant using the Black-Scholes pricing model with the following assumptions:
|  |  | Years Ended March 31,
|  |  | 2016 |  |  | 2015 |  |  | 2014
Expected volatility |  |  | 53% |  |  | 61% |  |  | 64%
Expected dividend yield |  |  | - |  |  | - |  |  | -
Risk-free interest rate |  |  | 1.5% to 1.8% |  |  | 1.4% to 1.9% |  |  | 0.7% to 2.2%
Weighted average expected option term |  |  | 5.4 years |  |  | 6.0 years |  |  | 6.1 years
Weighted average fair value of options granted |  | $ | 4.17 |  | $ | 4.14 |  | $ | 5.70
The estimated fair value of stock purchase rights granted under the Employee Stock Purchase Plan was estimated using the Black-Scholes pricing model with the following weighted-average assumptions:
|  |  | Years Ended March 31,
|  |  | 2016 |  |  | 2015 |  |  | 2014
Expected volatility |  |  | 43% |  |  | 49% |  |  | 40%

Weighted average expected rights term |  |  | 0.83 years |  |  | 0.80 years |  |  | 0.75 years
Weighted average fair value of rights granted |  | $ | 3.25 |  | $ | 2.52 |  | $ | 2.83
Stock Repurchases In February 2015, the Company's board of directors authorized the Company to purchase up to $20.0 million of its common stock from time to time until February 29, 2016 (the "2015 Repurchase Plan"). Share repurchases, if any, will be funded with available cash. Repurchases under the Repurchase Plan may be made through open market purchases at prevailing market prices or in privately negotiated transactions. The timing, volume and nature of share repurchases are subject to market prices and conditions, applicable securities laws and other factors, and are at the discretion of the Company's management. Share repurchases under the Repurchase Plan may be commenced, suspended or discontinued at any time. This tranche of shares authorized for repurchase expired in February 2016. In October 2015, the Company's board of directors authorized the Company to purchase an additional $15.0 million of its common stock from time to time until October 20, 2016 under the 2015 Repurchase Plan. The remaining authorized repurchase amount at March 31, 2016 was approximately $15.0 million. The stock repurchase activity as of March 31, 2016 is summarized as follows:
