(a)The fair value of foreign currency forward exchange contracts is based on dealer quotes of market forward rates and reflects the amount that the Company would receive or pay at their maturity dates for contracts involving the same currencies and maturity dates.
(b)These represent equity investments with a readily determinable fair value. The Company has measured its investments to fair value in accordance with ASC 321, Investments—Equity Securities, based on quoted prices in active markets.
(c)The fair value of the interest rate cap is based on market forward rates and volatility as of June 30, 2026.
The majority of the Company’s non-financial instruments, which include goodwill, intangible assets, inventories and property, plant and equipment, are not required to be re-measured to fair value on a recurring basis. These assets are evaluated for impairment if certain triggering events occur. If such evaluation indicates that impairment exists, the asset is written down to its fair value. In addition, an impairment analysis is performed at least annually for goodwill and indefinite-lived intangible assets. Furthermore, assets classified as held for sale are measured at the lower of their carrying amount or fair value less costs to sell. When the Company determines that the fair value of an asset group held for sale is less than its carrying value, a non-recurring fair value adjustment is recognized as a loss in the period the held-for-sale criteria are met. The Company estimated the fair value of the assets held for sale based on current market indicators.
Equity Investments Without Readily Determinable Fair Value
The Company evaluates its equity investments without readily determinable fair values for impairment if factors indicate that a significant decrease in value has occurred. The Company has elected to use the measurement alternative to fair value that will allow these investments to be recorded at cost, less impairment, and adjusted for subsequent observable price changes. The Company did not record any impairment charges on these investments during the three and nine months ended June 30, 2026 and recorded approximately $1 million and $4 million of impairment charges on these investments during the three and nine months ended June 30, 2025, respectively. In addition, there were no observable price change events that were completed during the three and nine months ended June 30, 2026 and 2025.
Fair Value of Debt
Based on the level of interest rates prevailing at June 30, 2026, the fair value of the Company’s debt was $4.609 billion. Based on the level of interest rates prevailing at September 30, 2025, the fair value of the Company’s debt was $4.270 billion. The fair value of the Company’s debt instruments is determined using quoted market prices from less active markets or by using quoted market prices for instruments with identical terms and maturities; both approaches are considered a Level 2 measurement.
