(a) The fair values presented are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments and/or discounted cash flow analyses.

(b) Fair value is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or cash flows.

(c) Fair value was determined by discounting anticipated future cash payments using rates currently available for instruments with similar remaining maturities.

(d) Fair value was determined based upon market prices of securities with similar terms and maturities.
