Estimated Fair Values For Certain Financial Assets And Financial Liabilities

For all other financial assets and financial liabilities, the carrying value is a reasonable estimate of the fair value as of September 30, 2015 and December 31, 2014. The carrying value and fair value for these assets and liabilities are equivalent because they are relatively short term in nature and there is no interest rate or credit risk that would cause the fair value to differ from the carrying value.

⁽¹⁾ At September 30, 2015, the carrying value of the FDIC receivable approximates the fair value due to the short term nature of the majority of loss share agreements. At December 31, 2014, the fair value of the FDIC receivable is estimated based on discounted future cash flows using current discount rates and excludes receivable related to accretable yield to be amortized in prospective periods.
