We determine the fair value of our security holdings based on pricing from our service providers and market prices from industry-standard independent data providers. Such market prices may be quoted prices in active markets for identical assets (Level 1 inputs), pricing determined using inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) or using unobservable inputs that are supported by little or no market activity (Level 3 inputs). Our non-marketable equity investments are not included in the table above and are discussed in Note 3. See Note 8 for the fair value measurement of our derivative contracts and Note 10 for the fair value measurement of our long-term debt, which are also not included in the table above. Our marketable equity investments are classified within Level 1 and were immaterial as of September 30, 2024 and December 31, 2023.
