The Company recorded stock based compensation expense of $170,562 and $24,535, which is included as part of selling, general and administrative expenses for the years ended April 30, 2015 and 2014, respectively.
 
The Company elected to adopt the shortcut method for determining the initial pool of excess tax benefits available to absorb tax deficiencies related to stock-based compensation. The shortcut method includes simplified procedures for establishing the beginning balance of the pool of excess tax benefits (the APIC Tax Pool) and for determining the subsequent effect on the APIC Tax Pool and the Company’s consolidated statements of cash flows of the tax effects of share-based compensation awards. Excess tax benefits related to share-based compensation are reflected as financing cash inflows.
 
The Company estimates the fair value of stock options granted using the Black-Scholes-Merton option-pricing model. The Company determines the forfeiture rate based on the historical forfeitures of stock options previously granted to employees and directors. The forfeiture rate was 15% for the years ended April 30, 2015 and 2014. Compensation cost is then recognized on a straight-line basis over the vesting or service period and is net of estimated forfeitures. The following assumptions were used to compute the fair value of stock options granted during the years ended April 30, 2015 and 2014:

The risk-free rate is based on the rate of U.S Treasury zero-coupon issues with a remaining term equal to the expected term of the option grants. Expected volatility is based on the historical volatility of the Company’s common stock using the weekly closing price of the Company’s common stock. The expected dividend yield is zero based on the fact that the Company has never paid cash dividends and has no present intention to pay cash dividends. The expected term represents the period that the Company’s stock-based awards are expected to be outstanding and was calculated using the simplified method.
