| Derivative and Financial Instruments                                    | Derivatives and Financial InstrumentsA derivative is a financial instrument that derives its cash flows, and therefore its value, by reference to an underlying instrument, index or referenced interest rate.  These instruments include interest rate swaps, caps, floors, collars, options or other financial instruments designed to hedge exposures to interest rate risk or for speculative purposes.Accounting guidance requires an entity to recognize all derivatives as either assets or liabilities in the balance sheet, and measure those instruments at fair value.  Changes in the fair value of those derivatives are reported in current earnings or other comprehensive income depending on the purpose for which the derivative is held and whether the derivative qualifies for hedge accounting.Mortgage banking derivatives used in the ordinary course of business consist of mandatory forward sales contracts or forward contracts and rate lock loan commitments.  The fair value of our derivative instruments is primarily measured by obtaining pricing from broker-dealers recognized to be market participants.During 2012, we began originating residential mortgage loans for sale in the secondary market.  We have established guidelines in originating, selling loans to Fannie Mae, and retaining or selling the loan servicing rights.  The commitments to borrowers to originate residential mortgage loans and the forward sales commitments to investors are freestanding derivative instruments. As such, they do not qualify for hedge accounting treatment, and the fair value adjustments for these instruments is recorded through the income statement in mortgage loan income. The fair market value of mortgage banking derivatives at June 30, 2013 was recorded in the consolidated balance sheet in Other Assets.
