The unrealized losses are primarily a result of increases in market yields from the time of purchase. In general, as market yields rise, the value of securities will decrease; as market yields fall, the fair value of securities will increase. There are 54 positions that are considered temporarily impaired at September 30, 2013. Management generally views changes in fair value caused by changes in interest rates as temporary; therefore, these securities have not been classified as other-than-temporarily impaired. Management has also concluded that based on current information we expect to continue to receive scheduled interest payments as well as the entire principal balance. Furthermore, management does not intend to sell these securities and does not believe it will be required to sell these securities before they recover in value.

Contractual maturities of securities at September 30, 2013 are shown below (in thousands). Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without prepayment penalties.
