Investments Classified by Contractual Maturity Date [Table Text Block]

The amortized cost and fair value of securities available for sale as of September 30, 2013, by contractual maturity, are shown in the following table. Certain securities have call features that allow the issuer to call the securities prior to maturity. Expected maturities may differ from contractual maturities in collateralized mortgage obligations and mortgage-backed securities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Therefore, collateralized mortgage obligations and mortgage-backed securities are not included in the maturity categories within the summary.
