As of December 31, 2025 and 2024, our available-for-sale securities included money market funds and time deposits and their carrying values were approximately equal to their fair values. Money market funds were measured using quoted prices in active markets, which represent Level 1 inputs and time deposits were measured at fair value using Level 2 inputs. Level 2 inputs are obtained from various third party data providers and represent quoted prices for similar assets in active markets, or these inputs were derived from observable market data, or if not directly observable, were derived from or corroborated by other observable market data.
Our derivative assets and liabilities include interest rate and foreign exchange derivatives that are measured at fair value using observable market inputs such as forward rates, interest rates, our own credit risk as well as an evaluation of our counterparties’ credit risks. Based on these inputs, the derivative assets and liabilities are classified within Level 2 of the fair value hierarchy.
There were no transfers between the different levels of the fair value hierarchy in 2025 or in 2024.
As of December 31, 2025 and 2024, the carrying amount of investments measured using the measurement alternative for equity investments without a readily determinable fair value was $4.3 million. The carrying amount, which is recorded within other non-current assets, is based on the latest observable transaction price.
As of December 31, 2025, the estimated fair values of the 2026 Notes, the 2030 Notes, the Secured Notes and the Tranche B-2 Dollar Term Loans were $1.2 billion, $1.3 billion, $1.5 billion and $1.9 billion, respectively. As of December 31, 2024, the estimated fair values of the 2026 Notes, the 2030 Notes, the Secured Notes and the Tranche B-2 Dollar Term Loans were $1.0 billion, $1.1 billion, $1.4 billion and $2.7 billion, respectively. The fair values of each of these debt facilities were estimated using quoted market prices obtained from brokers (Level 2).

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
