Stock and Stock-Based Incentive Plans | Stock and Stock-Based Incentive Plans (A) Share Repurchase Program As of May 31, 2020 , a total of $ 2.0 billion of board authorizations for repurchases of our common stock was outstanding, with no expiration date, of which $1.51 billion remained available for repurchase. Subsequent to the end of the fiscal year, our current stock repurchase program was suspended, although the repurchase authorization remains effective. Common Stock Repurchases Three Months Ended May 31 2020 2019 Number of shares repurchased (in thousands) 515.5 2,953.1 Average cost per share $ 78.96 $ 69.35 Available for repurchase, as of end of period (in millions) $ 1,511.6 $ 1,909.1 (B) Stock Incentive Plans We maintain long-term incentive plans for management, certain employees and the nonemployee members of our board of directors ("board"). The plans allow for the granting of equity-based compensation awards, including nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock awards, stock- and cash-settled restricted stock units, stock grants or a combination of awards. To date, we have no t awarded any incentive stock options. The majority of associates who receive share-based compensation awards primarily receive cash-settled restricted stock units. Senior management and other key associates receive awards of nonqualified stock options, stock-settled restricted stock units and/or restricted stock awards. Nonemployee directors receive awards of nonqualified stock options, stock grants, stock-settled restricted stock units and/or restricted stock awards. Excluding stock grants and stock-settled deferred stock units, all share-based compensation awards, including any associated dividend rights, are subject to forfeiture. Nonqualified Stock Options. Nonqualified stock options are awards that allow the recipient to purchase shares of our common stock at a fixed price. Stock options are granted at an exercise price equal to the fair market value of our common stock on the grant date. The stock options generally vest annually in equal amounts over four years . These options expire seven years after the date of the grant. Cash-Settled Restricted Stock Units. Also referred to as restricted stock units, or RSUs, these are awards that entitle the holder to a cash payment equal to the fair market value of a share of our common stock for each unit granted. For grants prior to fiscal 2021, conversion generally occurs at the end of a three -year vesting period. RSUs granted in fiscal 2021 vest annually in equal amounts over three years . However, the cash payment per RSU will not be greater than 200% or less than 75% of the fair market value of a share of our common stock on the grant date. The initial grant date fair values are based on the volume-weighted average price or closing price of our common stock on the grant dates. RSUs are liability-classified awards and do not have voting rights. Stock-Settled Market Stock Units. Also referred to as market stock units, or MSUs, these are restricted stock unit awards with market conditions granted to eligible key associates that are converted into between zero and two shares of common stock for each unit granted. Conversion generally occurs at the end of a three-year vesting period. The conversion ratio is calculated by dividing the average closing price of our stock during the final 40 trading days of the three -year vesting period by our stock price on the grant date, with the resulting quotient capped at two . This quotient is then multiplied by the number of MSUs granted to yield the number of shares awarded. The grant date fair values are determined using a Monte-Carlo simulation and are based on the expected market price of our common stock on the vesting date and the expected number of converted common shares. MSUs do not have voting rights. Other Share-Based Incentives Stock-Settled Performance Stock Units . Also referred to as performance stock units, or PSUs, these are restricted stock unit awards with performance conditions granted to eligible key associates that are converted into between zero and two shares of common stock for each unit granted. Conversion generally occurs at the end of a three -year vesting period. For the fiscal 2018 grants, the conversion ratio is based on the company reaching certain target levels set by the board for cumulative three-year pretax diluted earnings per share at the end of the three-year period, with the resulting quotient subject to meeting a minimum 25% threshold and capped at 200% ; based on the company's results for the three-year period, the board certified a performance adjustment factor of 119% . For the fiscal 2020 grants, the conversion ratio is based on the company reaching certain performance target levels set by the board of directors at the beginning of each one-year period, with the resulting quotients subject to meeting a minimum 25% threshold and capped at 200% . These quotients are then multiplied by the number of PSUs granted to yield the number of shares awarded. For the first-year period, these targets were based on annual pretax diluted earnings per share excluding any unrealized gains or losses on equity investments in private companies. The board certified a performance adjustment factor of 117% for the first-year period. For the second- and third-year periods, the remaining awarded 42,099 PSUs do not qualify as grants under ASC 718 as mutual understanding of the target performance levels are either not fully set or have not been set. The grant date fair values are based on the volume-weighted average prices of our common stock on the grant dates. PSUs do not have voting rights. No PSUs were awarded in fiscal 2021. As of May 31, 2020 , 21,053 granted units were outstanding at a weighted average grant date fair value per share of $78.61 . Stock-Settled Deferred Stock Units . Also referred to as deferred stock units, or DSUs, these are restricted stock unit awards granted to non-employee members of our board of directors that are converted into one share of common stock for each unit granted. Conversion occurs at the end of the one -year vesting period unless the director has exercised the option to defer conversion until separation of service to the company. The grant date fair values are based on the volume-weighted average prices of our common stock on the grant dates. DSUs have no voting rights. As of May 31, 2020 , 38,730 units were outstanding at a weighted average grant date fair value of $80.19 . Restricted Stock Awards . Restricted stock awards, or RSAs, are awards of our common stock that are subject to specified restrictions that generally lapse after a one - to three -year period from the date of the grant. The grant date fair values are based on the volume-weighted average prices of our common stock on the grant dates. Participants holding restricted stock are entitled to vote on matters submitted to holders of our common stock for a vote. As of May 31, 2020 , there were 4,517 shares outstanding at a grant date value of $88.54 .

The PSU expense is adjusted for any change in management’s assessment of the performance target level that is probable of being achieved. The variable expense associated with RSUs is recognized over their vesting period (net of estimated forfeitures) and is calculated based on the volume-weighted average price or closing price of our common stock on the last trading day of each reporting period. The total costs for matching contributions for our employee stock purchase plan are included in share-based compensation expense. There were no capitalized share-based compensation costs as of or for the three months ended May 31, 2020 or 2019 .

In computing the value of the option, the binomial model considers characteristics of fair-value option pricing that are not available for consideration under a closed-form valuation model (for example, the Black-Scholes model), such as the contractual term of the option, the probability that the option will be exercised prior to the end of its contractual life and the probability of termination or retirement of the option holder. For this reason, we believe that the binomial model provides a fair value that is more representative of actual experience and future expected experience than the value calculated using a closed-form model. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by the recipients of share-based awards.
