Fair Values of Financial Instruments |
Fair Values of Financial Instruments | Note 14 – Fair Values of Financial Instruments The estimated fair values approximate carrying amount for all items except those described in the following table. Securities available-for-sale fair values are based upon market prices or dealer quotes, and if no such information is available, on the rate and term of the security. The carrying value of FHLBC stock approximates fair value as the stock is nonmarketable and can only be sold to the FHLBC or another member institution at par. FHLBC stock is carried at cost and considered a Level 2 fair value. Fair values of loans were estimated for portfolios of loans with similar financial characteristics, such as type and fixed or variable interest rate terms. Cash flows were discounted using current rates at which similar loans would be made to borrowers with similar ratings and for similar maturities. The fair value of time deposits is estimated using discounted future cash flows at current rates offered for deposits of similar remaining maturities. The fair values of borrowings were estimated based on interest rates available to the Company for debt with similar terms and remaining maturities. The fair value of off balance sheet volume is not considered material. The carrying amount and estimated fair values of financial instruments were as follows:
