Note 10. Share-based Compensation and Other Benefit Plans:

The cost of employee services received in exchange for the award of equity instruments is based on the fair value of the award at the date of grant. Compensation cost is recognized using a straight-line method over the vesting period and is net of estimated forfeitures. Stock option exercises and stock awards are satisfied through the issuance of new shares. 

Equity incentive plan: The Company's Second Amended and Restated 2010 Equity Incentive Plan (the Second A&R 2010 Plan) provides for the granting of incentive and nonqualified stock options, restricted stock, restricted stock units, performance shares, performance units and stock appreciation rights. There were 7.5 million shares of common stock authorized for grant under the Second A&R 2010 Plan. In October 2020, the shareholders approved an amended and restated incentive plan - the 2020 Equity Incentive Plan. The maximum aggregate number of shares of common stock reserved and available for awards under the Amended Plan is 2,484,202 shares, which includes an additional 1,300,000 shares authorized by the 2020 Equity Incentive Plan. Shares issued after the shareholder meeting are issued under the 2020 Equity Incentive Plan. At June 30, 2021, there were 1.1 million shares of common stock available for grant under the 2020 Equity Incentive Plan. The maximum term of incentive options granted under the 2020 Equity Incentive Plan is ten years. The 2020 Equity Incentive Plan replaced the Company's second A&R 2010 Plan, which had previously amended and restated the Company's Amended and Restate 2010 Equity Incentive Plan (the A&R 2010 Plan). The A&R 2010 Plan had previously replaced the Company's 1998 Nonqualified Stock Option Plan (the 1998 Plan). The Second A&R 2010 Plan and the 1998 Plan (collectively, the Plans) are administered by the Board of Directors and its Executive Compensation Committee, which determine the persons who are to receive awards under the Plans, the number of shares subject to each award and the term and exercise price of each award. The number of shares of common stock subject to outstanding awards as of  June 30, 2021 under the 2020 Equity Incentive Plan were 3.7 million.

The fair values of options granted under the Plans were estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions used:

The dividend yield is based on the Company's historical annual cash dividend divided by the market value of the Company's common stock. The expected annualized volatility is based on the Company's historical stock price over a period equivalent to the expected life of the option granted. The risk-free interest rate is based on U.S. Treasury constant maturity interest rates with a term consistent with the expected life of the options granted.

Stock option activity under the Plans for the three years ended June 30, 2021, consists of the following (shares in thousands): 

The weighted average fair value of options granted during fiscal 2021, 2020, and 2019 was $59.75, $37.01, and $34.66 respectively. The total intrinsic value of options exercised during fiscal 2021, 2020, and 2019 were $145.6 million, $99.3 million, and $159.0 million, respectively. The total fair value of options vested during fiscal 2021, 2020, and 2019 were $70.5 million, $71.1 million, and $31.7 million, respectively.

Restricted common stock activity under the Plans for the three years ended June 30, 2021, consists of the following (units in thousands):

Restricted stock unit activity under the Plans for the three years ended June 30, 2021, consists of the following (units in thousands):

The total fair value of restricted stock units that vested was $6.7 million for fiscal 2021, $5.7 million for fiscal 2020, and $3.1 million for fiscal 2019. The restricted stock units vest over a three-year period.

The weighted average period over which the compensation cost is expected to be recognized is 2.1 years.
