Fair Value Option
Fair Value Option
FASB ASC Subtopic 825-10 permits entities to measure many financial instruments and certain other items at fair value and requires certain disclosures for amounts for which the fair value option is applied. The Corporation has elected to measure mortgage loans held for sale at fair value to more accurately reflect the financial performance of its mortgage banking activities in its consolidated financial statements. Derivative financial instruments related to these activities are also recorded at fair value, as noted within Note H, “Derivative Financial Instruments.” The Corporation determines fair value for its mortgage loans held for sale based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. Changes in fair value during the period are recorded as components of mortgage banking income on the consolidated statements of income. Interest income earned on mortgage loans held for sale is recorded within interest income on the consolidated statements of income.
The following table presents a summary of the Corporation’s mortgage loans held for sale:
