Cash, Cash Equivalents, and Restricted Cash
Cash, cash equivalents, and restricted cash are recorded at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs to valuation methodologies used to measure fair value:
Level 1—Valuations based on quoted prices in active markets for identical assets or liabilities.
Level 2—Valuations based on quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly through market corroboration.
Level 3—Valuations based on unobservable inputs reflecting our own assumptions used to measure assets and liabilities at fair value. These valuations require significant judgment.
The following table summarizes, by major security type, our cash, cash equivalents, and restricted cash that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy (in thousands):

Fair Value (1)
Cash$829,573 $995,802 
Level 1:
Restricted cash and cash equivalents:

Total cash, cash equivalents, and restricted cash$1,701,507 $1,527,881 
(1)    Due to the highly liquid nature of our investments, amortized cost approximates fair value.
Nonrecurring Fair Value Measurements
We hold equity investments in certain unconsolidated entities without a readily determinable fair value. These strategic investments represent less than a 20% ownership interest in each of the entities, and we do not have significant influence over or control of the entities. We use the measurement alternative to account for adjustments to these investments for observable transactions for the same or similar investments of the same issuer in any given quarter. If we determine an impairment has occurred, the investment is written down to the estimated fair value. As of June 30, 2025 and December 31, 2024,
such equity investments totaled $35.0 million and $33.0 million, respectively. No material adjustments to the carrying value of these equity investments were recorded for the three and six months ended June 30, 2025 and 2024.
