Explanation of Responses:

Id	Content
F1	Each market share unit converts into the number of shares of common stock determined by applying a payout factor to the target number of shares vesting on a given date. The payout factor is the greater of Total Return and relative total shareholder return (rTSR) Floor. Total Return is a ratio of the 10-day average closing stock price on the measurement date, plus the value of accumulated dividends, divided by the average stock price on the grant date (also a 10-day average). The minimum payout factor for Total Return performance that must be achieved to earn a payout is 80% and the maximum is 225%. The rTSR Floor feature provides a minimum level of payout if BMS stock price declines from the grant date but outperforms our peers based on their TSR percentile rank. A TSR percentile rank (i) below the 50th percentile yields a 0% payout, (ii) between the 50th and 74.99th percentiles yields a 50% payout, and (iii) at or above the 75th percentile yields a 100% payout.
F2	These market share units cliff vest on the third anniversary of the grant date, subject to certification of performance results by the Board.
F3	Each performance share unit converts into one share of common stock upon distribution in the first quarter of 2029, subject to certification of performance results by the Board.
