Stock-Based Compensation [Abstract] |
Stock-Based Compensation | Stock-Based Compensation The following table summarizes the stock-based compensation expense and related income tax effect for the three months ended:
| Three Months Ended |  |
(In millions) | August 28, 2021 |  | August 29, 2020 |  |  |  |
Stock-based compensation expense | $ | 15.1 |  |  | $ | 1.5 |  |  |  |  |
Related income tax effect | $ | 3.7 |  |  | $ | 0.3 |  |  |  |  |
The increase to Stock-based compensation expense was driven in part by the additional of Knoll's equity-based compensation awards. This impact includes the accelerated stock-compensation award expense related to workforce reductions as part of the Knoll integration. Certain of the Company's equity-based compensation awards contain provisions that allow for continued vesting into retirement. Stock-based awards are considered fully vested for expense attribution purposes when the employee's retention of the award is no longer contingent on providing subsequent service.
