13. SHARE-BASED COMPENSATION

Our outstanding share-based compensation programs include deferred stock units and stock options. During the six months ended 31 March 2025, we granted market-based and time-based deferred stock units. Under all programs, the terms of the awards are fixed at the grant date. We issue shares from treasury stock upon the payout of deferred stock units and the exercise of stock options. As of 31 March 2025, there were 0.8 million shares available for future grant under our Long-Term Incentive Plan ("LTIP"), which is shareholder approved.

Share-based compensation cost recognized on the consolidated income statements is summarized below:

(A)Fiscal year 2025 includes noncash executive separation costs of $22.4 to accelerate vesting of share-based awards. Refer to the "Shareholder Activism-Related Costs" disclosure in Note 17, Supplemental Information, for additional information.

Before-tax share-based compensation cost is primarily included in "Selling and administrative expense" on our consolidated income statements. The amount of share-based compensation cost capitalized in the first six months of fiscal years 2025 and 2024 was not material.

Deferred Stock Units

During the six months ended 31 March 2025, we granted 95,490 market-based deferred stock units. The market-based deferred stock units are earned over the performance period beginning 1 October 2024 and ending 30 September 2027, conditioned on the level of our total shareholder return in relation to the S&P 500 Index over thethree-year performance period.

The market-based deferred stock units had an estimated grant-date fair value of $470.13 per unit, which was estimated using a Monte Carlo simulation model. The model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the grant and calculates the fair value of the awards. We generally expense the grant-date fair value of these awards on a straight-line basis over the applicable vesting period. The calculation of the fair value of market-based deferred stock units used the following assumptions:

In addition, during the six months ended 31 March 2025, we granted 125,282 time-based deferred stock units at a weighted average grant-date fair value of $332.36.
