  1. The DERs accrued on five outstanding RSU awards and vest proportionately with the RSUs to which they relate. The number of DERs is calculated as of the dividend record date by multiplying the dividend per share ($1.25) by the number of outstanding RSUs, and, to the extent applicable, previously accrued DERs and then dividing the result by the fair value of the common share on the dividend payment date. Each DER is the economic equivalent of one share. Excludes DERs that accrued on outstanding RSUs prior to June 2, 2026, which are reflected in outstanding RSUs. Restricted stock units (RSUs) convert into Class A Common Shares on a one-for-one basis. The RSUs vested on June 2, 2026. Amounts reported include DERs that accrued on the RSUs prior to June 2, 2026.

Restricted stock units (RSUs) financial
"Restricted stock units (RSUs) convert into Class A Common Shares on a one-for-one basis."
Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

"Settlement of Dividend Equivalent Rights (DERs) that accrued on June 2, 2026 and were settled in shares on vesting of the related RSUs."
tax withholding obligations financial
"Represents shares withheld to pay tax withholding obligations due on the date of vesting of RSUs; not a market transaction."
derivative security financial
"Exercise or conversion of derivative security"
A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.
