Derivatives [Abstract]  
Derivatives

The Company may use derivatives to hedge the risk of changes in the fair values of interest rate lock commitments, residential mortgage loans held for sale, and mortgage servicing rights. None of the Company's derivatives are designated as hedging instruments. Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in income. The Company primarily utilizes forward interest rate contracts in its derivative risk management strategy.
