The amortized cost and fair value of investment securities as of September 30, 2015, by contractual maturity, are shown hereafter. Expected maturities will differ from contractual maturities because issuers have the right to call or prepay obligations with or without call or prepayment penalties. This is often the case with mortgage-backed securities, which are disclosed separately in the table below.

Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.

At September 30, 2015, the debt securities with unrealized losses have depreciated 2.35 percent from the Company’s amortized cost basis. These securities are guaranteed by either the U.S. Government, other governments or U.S. corporations. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred and the results of reviews of the issuer’s financial condition. The unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying securities were purchased. As management has the ability to hold debt securities until maturity, or for the foreseeable future if classified as available-for-sale, no declines are deemed to be other than temporary.
