​ At each reporting date, we review our investments to determine whether a decline in fair value below the amortized cost basis is other-than-temporary. To determine whether a decline in value is other-than-temporary, we consider all available evidence, including our overall financial condition, the severity and duration of the decline in fair value, and our intent and ability to hold the investment for a reasonable period of time sufficient for any forecasted recovery. If a decline in value is deemed other-than-temporary, we record a reduction in the carrying value to the estimated fair value. We reviewed our portfolio of investments as of December 31, 2024 and 2023 and determined that no other-than-temporary market value impairment exists.
