_______________ (1)$439.2 million of cash and $360.1 million of money market deposit accounts are not subject to recurring fair value measurement and therefore excluded from this table. However, these balances are included within the $1.8 billion of cash and cash equivalents and short-term investments on the condensed consolidated balance sheets. (2)$3.0 million of restricted cash is not subject to recurring fair value measurement and is therefore excluded from this table. However, this balance is included within the $1.9 billion of restricted cash and cash equivalents and restricted investments on the condensed consolidated balance sheets. The following are the hierarchical levels of inputs to measure fair value: Level 1 Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 Inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 Unobservable inputs reflecting our own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. During the six months ended June 30, 2026, the Company did not make any transfers between the levels of the fair value hierarchy.
