On August 7, 2013, our stockholders approved the Eagle Materials Inc. Amended and Restated Incentive Plan (the Plan), which increased the shares we are authorized to issue as awards by 3,000,000 (1,500,000 of which may be stock awards). Under the terms of the Plan, we can issue equity awards, including stock options, restricted stock units (RSUs), restricted stock, and stock appreciation rights to employees of the Company and members of the Board of Directors. The Compensation Committee of our Board of Directors specifies the terms for grants of equity awards under the Plan.

In May 2021, the Compensation Committee of the Board of Directors approved the granting to certain officers and key employees an aggregate of 4,293 performance-vesting stock options that will be earned only if certain performance conditions are satisfied (the Fiscal 2022 Employee Performance Stock Option Grant). The performance criteria for the Fiscal 2022 Employee Performance Stock Option Grant is based upon the achievement of certain levels of return on equity (as defined in the option agreements), ranging from 10.0% to 20.0%, for the fiscal year ending March 31, 2022. All stock options will be earned if the return on equity is 20.0% or greater, and the percentage of shares earned will be reduced proportionately to approximately 66.7% if the return on equity is 10.0%. If the Company does not achieve a return on equity of at least 10.0%, all granted stock options will be forfeited. Following any such reduction, restrictions on the earned stock options will lapse and the earned options will vest ratably over four years, with the initial fourth vesting promptly following the determination date, and the remaining options vesting on March 31, 2023 through 2025. The stock options have a term of ten years from the date of grant. The Compensation Committee also approved the granting of 3,578 time-vesting stock options to the same officers and key employees, which vest ratably over four years (the Fiscal 2022 Employee Time-Vesting Stock Option Grant).

The weighted-average assumptions used in the Black-Scholes model to value the option awards in fiscal 2022 are as follows:

Stock option expense for all outstanding stock option awards totaled approximately $0.7 million and $1.7 million for the three months ended June 30, 2021 and 2020, respectively. At June 30, 2021, there was approximately $6.3 million of unrecognized compensation cost related to outstanding stock options, which is expected to be recognized over a weighted-average period of 2.3 years.

The following table represents stock option activity for the three months ended June 30, 2021:

	Number of Shares			Weighted- Average Exercise Price

The following table summarizes information about stock options outstanding at June 30, 2021:

	Options Outstanding						Options Exercisable

$59.32 - $81.56		218,382		7.56	$	64.92		88,160	$	70.97
$87.34 - $93.03		200,296		6.63	$	90.84		116,623	$	90.31

At June 30, 2021, the aggregate intrinsic value for both of the outstanding and exercisable options was approximately $34.9 million and $18.7 million, respectively. The total intrinsic value of options exercised during the three months ended June 30, 2021 was approximately $5.6 million.

In May 2021, the Compensation Committee approved the granting to certain officers and key employees an aggregate of 52,577 shares of performance-vesting restricted stock that will be earned if certain performance conditions are satisfied (the Fiscal 2022 Employee Restricted Stock Performance Award). The performance criteria for the Fiscal 2022 Employee Restricted Stock Performance Award is based upon the achievement of certain levels of return on equity (as defined in the award agreement), ranging from 10.0% to 20.0%, for the fiscal year ending March 31, 2022. All restricted shares will be earned if the return on equity is 20.0% or greater, and the percentage of shares earned will be reduced proportionately to approximately 66.7% if the return on equity is 10.0%. If the Company does not achieve a return on equity of at least 10.0%, all awards will be forfeited. Following any such reduction, restrictions on the earned shares will lapse ratably over four years, with the initial fourth lapsing promptly following the determination date, and the remaining restrictions lapsing on March 31, 2023 through 2025. The Compensation Committee also approved the granting of 43,816 shares of time-vesting restricted stock to the same officers and key employees, which vest ratably over four years (the Fiscal 2022 Employee Restricted Stock Time-Vesting Award). The Fiscal 2022 Employee Restricted Stock Performance Award and the Fiscal 2022 Employee Restricted Stock Time-Vesting Award were valued at the closing price of the stock on the date of grant and are being expensed over a four-year period.

The fair value of restricted stock is based on the stock price at the date of grant. The following table summarizes the activity for nonvested restricted shares during the three months ended June 30, 2021:

	Number of Shares			Weighted-Average Grant Date Fair Value
Nonvested Restricted Stock at March 31, 2021		267,090		$	62.56
Granted		96,393		$	139.25
Vested		(20,685	)	$	60.21
Forfeited		(5,218	)	$	75.10
Nonvested Restricted Stock at June 30, 2021		337,580

Expense related to restricted shares was approximately $1.8 million and $3.0 million for the three months ended June 30, 2021 and 2020 respectively. At June 30, 2021, there was approximately $23.8 million of unearned compensation from restricted stock, which will be recognized over a weighted-average period of 2.9 years.

The number of shares available for future grants of stock options, restricted stock units, stock appreciation rights, and restricted stock under the Plan was 3,396,823 at June 30, 2021.
