The fair value or change in fair value of equity awards reflected in the tables above were determined as follows:
• |  | For restricted stock awards and restricted stock units, using the closing stock price on the applicable year-end or vesting date.

• |  | For PRSUs, using the closing stock price on the applicable year-end or vesting date and adjusted for the estimated performance achievements, as applicable.
Peer Group Total Shareholder Return (column c): Our peer group total shareholder return is calculated using the Standard & Poor’s Consumer Durables & Apparel Index, which we use for the stock performance graph required by Item 201(e) of Regulation S-K, from December 31, 2019 through December 31 of the applicable listed year. Net Income (column d): Net income as reflected in the table above is as reported in our financial statements and is calculated in accordance with accounting guidelines. In 2021, our net income, as reported, was negatively impacted by non-recurring expense related to debt extinguishment and the settlement of our qualified domestic defined benefit pension plans. Company Selected Measure - Operating Profit (column e): Operating profit is the highest weighted financial performance metric in our annual performance program. To calculate our operating profit for purposes of this program we adjust our reported operating profit to exclude the effect of special charges and certain other non-recurring income and expenses. Operating profit is also a measure used in our calculation of ROIC under our LTIP. See “Our 2022 Annual Performance Program” above for a description of these adjustments for 2022. |  |
