NOTE 9 – STOCK-BASED COMPENSATION

The Company’s board of directors may make awards under the 2011 Stock Plan (the “Stock Plan”) to officers, directors and key employees. Awards may include incentive stock options (“ISOs”), nonqualified stock options (“NSOs”), and restricted or unrestricted stock. All stock options awarded under the Stock Plan shall have an exercise price per share at least equal to the common stock’s market value per share at the date of grant. ISOs shall have a term no longer than ten years; NSOs may have up to a ten-year term. In the past, stock options typically became exercisable one year from the date of award. Commencing in January 2018, stock options have been awarded with three-year vesting schedules. As of July 31, 2019, there were approximately 1.7 million shares of the Company’s common stock reserved for issuance under the Company’s stock plan. This number includes 520,000 shares of the Company’s common stock available for future awards.

The total intrinsic value of the stock options exercised during the six months ended July 31, 2019 was $1.4 million. The total intrinsic value of the stock options exercised during the six months ended July 31, 2018 was not material. At July 31, 2019, the aggregate market value amounts of the shares of common stock subject to outstanding and exercisable stock options that were "in-the-money" exceeded the aggregate exercise prices of such options by $4.5 million and $4.2 million, respectively.

The Company estimates the fair value of each stock option on the date of award using the Black-Scholes pricing model. The Company believes that its past stock option exercise activity is sufficient to provide it with a reasonable basis upon which to estimate the expected life of newly awarded stock options. The fair value amounts for stock options granted during the periods presented herein were estimated on the corresponding dates of award based on the following weighted average assumptions:


	Six Months Ended July 31,
	2019		2018
Dividend yield	2.0	%	2.7	%
Expected volatility	34.0	%	36.0	%
Risk-free interest rate	2.4	%	2.0	%
Expected life (in years)	3.3		3.3

In April 2019 and 2018, and pursuant to terms of the Stock Plan, the Company awarded performance-based restricted stock units to two senior executives covering up to 36,000 shares of common stock at each date plus a number of shares to be determined based on the amount of cash dividends deemed paid on shares earned pursuant to the awards. The release of the stock restrictions depends on the total shareholder return performance of the Company’s common stock measured against the performance of a peer-group of common stocks over three-year periods.The award-date fair value am.ounts for restricted stock units are determined by using the per share market price of the Company’s common stock on the dates of award and the target number of shares for the award, by assigning equal probabilities to the thirteen possible payout outcomes at the ends of the three-year vesting periods, and by computing the weighted average of the outcome amounts. For each case, the estimated fair value amount was calculated to be 88.5% of the aggregate market value of the target number of shares on the award date.

The fair values of stock options and restricted stock units are recorded as stock compensation expense over the vesting periods of the corresponding awards. Expense amounts related to stock awards were $0.9 million for the six months ended July 31, 2019 and 2018. At July 31, 2019, there was $4.4 million in unrecognized compensation cost related to outstanding stock awards that the Company expects to expense over the next three years.
