Available-for-sale Securities, Continuous Unrealized Loss Position, Fair Value | The unrealized losses on the Company’s investments in mortgage-backed securities were caused by interest rate changes. The Company expects to recover the amortized cost bases over the term of the securities. Because the Company does not intend to sell the investments and it is not likely that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be upon maturity, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2018.
