| Unrealized losses on securities have not been recognized into income because the securities are of high credit quality or have undisrupted cash flows. Management has the intent and ability to hold the securities for the foreseeable future, and the decline in fair value is largely due to changes in interest rates and volatility in the securities markets. The fair values are expected to recover as the securities approach maturity
