Note 14: | Initial Adoption of Fair Value Option
ASC Topic 825, Financial Instruments, permits entities to measure recognized financial assets and financial liabilities using either historical cost or the fair value option at specified election dates. During 2013, the Company began using derivative financial instruments to manage exposure to interest rate risk in its mortgage banking business. These derivative financial instruments are recorded at fair value with changes in fair value reflected in noninterest income on the consolidated statements of income. To mitigate the volatility reported in earnings caused by measuring related assets and liabilities differently, the Company has elected the fair value option for the hedged item, mortgage loans held for sale under mandatory pricing agreements, that were originated on or after April 1, 2013. The Company continues to record mortgage loans held for sale under best-efforts pricing agreements at the lower of cost or fair value. Prior to April 1, 2013, all mortgage loans held for sale were carried at the lower of cost or fair value. Electing the fair value option had the following effect on the 2013 financial statements:
