The Company's held-to-maturity investments are debt instruments with fixed interest rates. Interest rates have increased in the period subsequent to the purchase of the investments. In general, increasing interest rates decrease the value of fixed rate debt instruments. Management believes the unrealized losses on the Company's held-to-maturity portfolio is primarily driven by increases in interest rates. Management considered the short time maturity of the investments, quality of the investments, and its intent and ability to hold the investments to maturity and determined the loss to be temporary.
