The Company has two share-based compensation plans: Amended and Restated Stock-Based Incentive Compensation Plan for Officers and Key Employees (the "Omnibus Plan") and the Stock-Based Compensation Plan for Non-Employee Directors ("Director's Plan"). The Company recognizes compensation cost based on the fair value of the awards on the date of grant. The compensation cost is recognized over the requisite service period of the award, which is generally the shorter of the vesting period that the holder is required to provide service, or the period from the grant date to the date on which the employee is eligible to retire. Upon retirement, as defined in the Company's share-based compensation plans, outstanding awards are subject to certain accelerated vesting terms.

Awards granted under the share-based compensation plans are paid from shares held in treasury and newly issued shares. The total compensation cost that has been charged against income related to these share-based compensation plans was $10.4 million, $10.9 million and $17.6 million for the fiscal years ended June 30, 2021, 2020 and 2019, respectively.

The Omnibus Plan provides that the Board of Directors or a designated committee may grant stock options, restricted stock and restricted stock units, and determine the terms and conditions of each grant. The Omnibus Plan provides the Chief Executive Officer with limited authority to grant awards. As of June 30, 2021, 3,283,626 shares were available for awards which may be granted under this plan.

Stock options granted under the plans above are granted with an exercise price equal to at least the fair market value of the Company's common stock on the date of grant. The options are typically exercisable after one to three years of service and expire no longer than ten years from the grant date.

The assumptions are based on multiple factors, including historical exercise patterns of employees in relatively homogeneous groups with respect to exercise and post-vesting employment termination behaviors, expected future exercising patterns for these same homogeneous groups and the implied volatility of our stock price based on historical performance for the same expected term of the options granted. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of each grant.

The weighted average grant date fair value of options awarded during fiscal years 2021, 2020 and 2019 was $5.39, $13.57 and $18.35, respectively. Share-based compensation charged against income related to stock options for the years ended June 30, 2021, 2020 and 2019 was $1.1 million, $2.1 million and $3.6 million, respectively. As of June 30, 2021, $0.3 million of compensation cost related to nonvested stock options will be recognized over a weighted average remaining life of 0.7 years.

Restricted stock unit awards are granted to employees with performance and/or service conditions. Earned restricted stock unit awards receive non-forfeitable cash dividends during the restriction period. The fair value of the restricted stock unit awards is determined based on the close price of the Company's stock on the grant date.

Performance-based restricted stock unit awards are earned dependent upon how certain performance goals are achieved during a specified performance period according to the terms determined at the date of the grant. These shares typically vest upon approval of attainment of the specified performance goals. Compensation cost is determined and charged to expense beginning in the performance period through the vesting period.

Amounts charged to compensation expense for restricted stock unit awards were $6.6 million, $8.1 million and $9.8 million for the years ended June 30, 2021, 2020 and 2019, respectively. As of June 30, 2021, $5.4 million of compensation cost related to restricted stock unit awards remains to be recognized over a weighted average remaining life of 1.5 years.

The Company granted performance-based awards in fiscal years 2021, 2020 and 2019 within the Omnibus Plan. The awards are granted at a target number of shares. These awards are earned dependent upon how certain performance goals are achieved during a specified performance period according to the terms determined at the date of the grant. The actual number of shares awarded may range from a minimum of 0 percent of the target shares to a maximum of 200 percent of the target shares. The fiscal year 2020 and 2019 awards were amended for a maximum attainment of 100 percent. Participants do not have any rights to dividends (or equivalents) during the performance period. These shares typically vest on the date of the attainment of the specified performance goals. Compensation cost is determined and charged to expense beginning in the performance period through the vesting period. In fiscal year 2021 expense of $1.6 million was recognized for these awards. In fiscal year 2020, a benefit of $1.4 million was recognized for these awards due to reversals for attainment based on performance. Compensation cost related to these awards granted in fiscal year 2019 was $1.4 million.

The Company granted Total Stockholder Return ("TSR") awards in fiscal year 2018. The TSR awards are granted at a target number of shares. The TSR awards are earned based on the Company's total stockholder return compared to the total stockholder returns of the Russell RSCC Materials & Processing Growth Index at the end of a three-year period. The actual number of shares awarded may range from a minimum of 0 percent of the target shares to a maximum of 200 percent of the target shares. Participants do not have any rights to dividends (or equivalents) during the performance period. The fair value of the TSR awards was estimated using Monte Carlo valuation models. Compensation cost related to TSR awards recognized in fiscal years 2021, 2020 and 2019 was $0.0 million, $0.9 million and $1.7 million, respectively. These awards were fully vested in fiscal year 2020 and distributed in fiscal year 2021.

According to the provisions of the Director's Plan, on the date of each annual stockholders' meeting or on such other regularly scheduled date as the Board of Directors may determine from time to time in light of the Company's prevailing practices for the grant of equity awards to employees, each Director shall be granted, in place of cash compensation, a number of stock units determined by dividing 50 percent of the Director's annual retainer by the fair market value of the Company's common stock on that date. These stock units vest as to one-quarter of the units for every three months of service following the grant date and are fully vested on the first anniversary of the grant date. At the Director's election, the remaining 50 percent of the annual retainer and 100 percent of committee chair fees may be paid in stock units in lieu of cash. These units are immediately vested.

In addition to the grant of retainer stock units described above, each Director may be granted annually an additional award of stock units as the Board may determine by resolution. These stock units vest as to one-quarter of the units for every three months of service following the grant date and are fully vested on the first anniversary of the grant date.
