Investments, Debt and Equity Securities [Abstract]

Investment in Securities Investment securities available-for-sale are recorded at fair value on a recurring basis. The Company’s investment securities available-for-sale are measured at fair value using Level 2 valuations. The market evaluation utilizes several sources which include “observable inputs” rather than “significant unobservable inputs” and therefore fall into the Level 2

category. The amortized cost, gross unrealized gains, gross unrealized losses and fair value of investment securities are summarized as follows:
