Explanation of Responses:

Id	Content
F1	Shares of Common Stock acquired from vested equity awards granted under the Issuer's Long-term Incentive Plan ("LTIP").
F2	Restricted stock units ("RSUs") vest in 1/3 increments on the dates of the Compensation Committee's first-quarter meetings held in the first, second, and third years after the grant date. Each RSU represents the right to receive one share of Common Stock upon vesting, and does not expire. These RSUs accrue quarterly dividend equivalents in the form of additional RSUs representing common stock dividends as approved by the Issuer's board of directors, which vest on the same schedule as the underlying RSU award.
F3	The RSU award acquired approximately 48 additional shares through automatic dividend reinvestment since February 10, 2025.
F4	Performance share award granted under the LTIP for the three-year performance period referenced in Column 1 based upon the Compensation Committee's determination of performance achieved for the period. Each performance share represents the right to receive one share of Common Stock upon vesting. These performance shares do not accrue quarterly dividends. Performance share award vests immediately on the grant date.
