At June 30, 2019, unrealized losses in the investment securities portfolio relating to debt securities totaled $577,000. The unrealized losses on these debt securities arose due to changing interest rates and are considered to be temporary. From the June 30, 2019 tables above, 20 out of 50 securities issued by U.S. Government sponsored enterprises contained unrealized losses. These unrealized losses are considered temporary because of acceptable financial condition and results of operations of entities that issued each security and the repayment sources of principal and interest on U.S. Government sponsored enterprises, including mortgage-backed securities, are government backed.

The amortized cost and estimated fair value of investment securities available for sale at June 30, 2019, by contractual maturity, are shown below. Expected maturities of mortgage-backed securities will differ from contractual maturities because borrowers have the right to call or prepay obligations with or without call or prepayment penalties.
