1.Money market funds are valued at the closing price reported by the fund sponsor and classified as marketable securities on the Consolidated Balance Sheets.

2.The fair value of cross currency interest rate swaps is calculated by discounting the estimated future cash flows based on the applicable observable yield curves. See Note 9. Financial instruments, for further information.

3.The fair value of forward currency contracts is estimated by discounting the difference between the contractual forward price and the current available forward price for the residual maturity of the contract using observable market rates. See Note 9. Financial instruments, for further information.

4.Fair values of quoted investments are based on current bid prices as of August 31, 2023 and August 31, 2022.

5.Includes investments in Treasury debt securities.

6.The fair value of the derivative was derived from a Black-Scholes valuation. The inputs used in valuing the derivative included observable inputs such as the floor and cap prices of the VPF, dividend yield of Cencora shares, risk free interest rate, and contractual term of the instrument, as well as unobservable inputs such as implied volatility of Cencora shares (ranging from 23.2% - 24.7% for the lower strike and 18.1% - 19.1% for the upper strike). See Note 9. Financial instruments, for further information.
