Quarterly Financial Information Disclosure [Abstract] |
UNAUDITED QUARTERLY FINANCIAL INFORMATION | 28. UNAUDITED QUARTERLY FINANCIAL INFORMATION As discussed in Note 1 - Summary of Significant Accounting Policies, on December 31, 2016, the Company elected to reclassify loan servicing fees, amortization of mortgage servicing rights, net gain on sale of residential mortgage loans, and unrealized gain (loss) on interest rate locks into a single line item called "mortgage banking income" in the Company’s consolidated statements of income. Loan servicing fees and net gain on sale of residential mortgage loans were previously recorded in its own line in the other operating income section of the consolidated statements of income, while unrealized gain (loss) on interest rate locks was included as a component of other operating income - other. The amortization of mortgage servicing rights was previously recorded as a component of amortization and impairment of other intangible assets in the other operating expense section of the Company’s consolidated statements of income. The components of mortgage banking income are disclosed in Note 15 - Mortgage Banking Income to the consolidated financial statements. The Company believes the reclassification provides a better presentation of revenues and costs of our mortgage banking activities. The following unaudited quarterly financial information has been adjusted retrospectively for the reclassification.
