Our investments generally consist of highly rated securities, substantially all of which are directly or indirectly backed by the U.S. federal government, as our investment policy restricts our investments to highly liquid, low credit risk assets. As such, we have not recorded any credit-related impairment loss during the three and six months ended June 30, 2026 or 2025 on our available-for-sale investment securities. Unrealized losses as of June 30, 2026 and December 31, 2025 are the result of increases in interest rates relative to when they were purchased as a portion of our investment portfolio is comprised of fixed rate securities. The underlying securities within our investment portfolio that were in an unrealized loss position as of June 30, 2026 and December 31, 2025 was due to the timing of our investment purchases, as a significant portion of our investments were purchased prior to increases in interest rates by the Board of Governors of the Federal Reserve (the "Federal Reserve"), and general volatility in market conditions.

Except as disclosed below, we do not currently intend to sell our remaining investments, and we have determined that it is more likely than not that we will not be required to sell our investments before recovery of their amortized cost bases, which may be at maturity.

In April 2025, we sold certain available-for-sale securities in order to reposition the proceeds into higher yielding assets. As a result, we recorded a realized loss of approximately $24.8 million during the first half of 2025 because we no longer had the intent to hold the securities until recovery of their amortized cost bases. The losses were reflected as a component of other income and expense, net on our consolidated statement of operations.
