(A)Marketable securities and other investments consist of funds maintained for the payment of benefits associated with nonqualified retirement plans. The funds include equity securities listed in active markets, municipal obligations valued by a third-party using valuation techniques that utilize inputs that are derived principally from or corroborated by observable market data, and money market funds with maturities of three months or less. Based on the short-term nature of these money market funds, carrying value approximates fair value. As of July 31, 2024, our municipal obligations are scheduled to mature as follows: $1.5 in 2025, $0.8 in 2026, $3.9 in 2027, $0.4 in 2028, $3.4 in 2029, and the remaining $7.2 in 2030 and beyond.

(B)Level 1 commodity and foreign currency exchange derivatives are valued using quoted market prices for identical instruments in active markets. Level 2 commodity and foreign currency exchange derivatives are valued using quoted prices for similar assets or liabilities in active markets. For additional information, see Note 10: Derivative Financial Instruments.

(C)Long-term debt is composed of public Senior Notes, which are traded in an active secondary market and valued using quoted prices. For additional information, see Note 8: Debt and Financing Arrangements.
