Stock Options and Share-Based Compensation | Note 5—Stock Options and Share-Based Compensation The stockholders approved the 2010 Stock Option Plan for Directors (“2010 Plan”) in fiscal year 2011 which allows the Company to grant options on an aggregate of 100,000 shares of the Company’s common stock. Under this plan, each eligible director was granted options to purchase 10,000 shares at the fair market value at the date of grant for a term of five years. These options are exercisable in four equal installments, one-fourth becoming exercisable on the next August 1 following the date of grant, and one-fourth becoming exercisable on August 1 of each of the next three years. At April 30, 2017, there were 25,000 shares available for future grants under the 2010 Plan. The stockholders approved the 2008 Key Employee Stock Option Plan (“2008 Plan”) in fiscal year 2009 which allowed the Company to grant options on an aggregate of 300,000 shares of the Company’s common stock. On August 26, 2015, the stockholders approved an amendment to this plan to increase the number of shares available under the 2008 Plan by 300,000. Under the plan, options are granted at not less than the fair market value at the date of grant and options are exercisable in such installments, for such terms (up to 10 years), and at such times, as the Board of Directors may determine at the time of the grant. At April 30, 2017, there were 255,100 shares available for future grants under the 2008 Plan. The Company recorded stock-based compensation expense in accordance with ASC 718. In order to determine the fair value of stock options on the date of grant, the Company applied the Black-Scholes option pricing model. Inherent in the model are assumptions related to expected stock-price volatility, option life, risk-free interest rate, and dividend yield. For stock options granted during the fiscal years 2017, 2016 and 2015, the Company believes that its historical share option experience does not provide a reasonable basis upon which to estimate expected term. The stock options granted have the “plain-vanilla” characteristics as defined in SEC Staff Accounting Bulletin No. 107 (SAB 107). The Company utilized the Safe Harbor option “Simplified Method” to determine the expected term of these options in accordance with the guidance of SAB 107 for options granted. The Company intends to continue to utilize the “Simplified Method” for future grants in accordance with the guidance of SAB 110 until such time that the Company believes that its historical share option experience will provide a reasonable basis to estimate expected term. The fair value of the options granted as shown below was estimated using the Black-Scholes model with the following assumptions:
|  | 2017 |  | 2016 |  | 2015
|  | 2008 Plan |  | 2008 Plan |  | 2008 Plan |  | 2010 Plan

Estimated fair value of each option |  | $5.04 |  | $3.97 |  | $6.60 |  | $3.04
The stock-based compensation expense is recorded over the vesting period (4 years) for the options granted, net of tax. The Company recorded $199,000, $192,000 and $196,000 of compensation expense and $74,000, $72,000 and $75,000 deferred income tax benefit in fiscal years 2017, 2016 and 2015, respectively. The remaining compensation expense of $381,000 and deferred income tax benefit of $141,000 will be recorded over the remaining vesting periods. The Company issued new shares of common stock and treasury stock to satisfy options exercised during fiscal years 2017, 2016 and 2015.
