Significant Accounting Policies |
Significant Accounting Policies | Note 2. Significant Accounting Policies ​ Cash, Cash Equivalents, Short-term Investments, and Long-term Investments ​ Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities of 90 days or less. Cash equivalents consist primarily of money market funds, U.S. government and agency securities and deposit accounts. Cash equivalents are carried on the balance sheet at fair market value. Short-term investments are highly liquid investments, primarily consisting of U.S. government and agency securities, with original maturities of greater than 90 days but less than one year from date of purchase. Long-term investments consist of U.S. government and agency securities with original maturities greater than one year from the date of purchase. Beginning as of March 31, 2025, both our short-term and long-term investments are classified as available-for-sale as a result of the below noted sale of securities. In prior periods, our short-term investments were classified as held-to-maturity. We classify our long-term investments as non-current based on the security’s contractual maturity. We evaluate if any declines in fair value below amortized cost are caused by expected credit losses, as well as our ability and intent to hold the investment until a forecasted recovery occurs. Any unrealized gains and losses are included in accumulated other comprehensive loss in the Consolidated Statement of Stockholders’ Equity. Income related to these securities is recorded in interest income in the Consolidated Statements of Operations. As of June 30, 2025, the amortized cost and fair value of the available-for-sale short-term investments was $376.3 million and $376.2 million, respectively. As of June 30, 2025, the amortized cost and fair value of the long-term investments was $31.0 million and $31.1 million, respectively. As of June 30, 2025, we had no allowances for credit loss on our investments. ​ In February 2025, we sold securities classified as held-to-maturity with a total net carrying value of $199.5 million. The majority of the proceeds were reinvested back into short-term investments during the three months ended March 31, 2025. Due to this sale, the remaining held-to-maturity securities were reclassified as available-for-sale, resulting in a remeasurement increase in short-term investments for balance sheet presentation purposes with a corresponding adjustment to accumulated other comprehensive loss of $81.0 thousand as of March 31, 2025. ​
