| Mortgage Servicing Rights              | Mortgage Servicing RightsFASB ASC Topic 860 "Transfers and Servicing" requires all separately recognized servicing assets and servicing liabilities to be initially measured at fair value, if practicable. The Company's servicing assets and servicing liabilities are reported using the amortization method and carried at the lower of amortized cost or fair value by strata. In evaluating the carrying values of mortgage servicing rights, the Company obtains third party valuations based on loan level data including note rate, type and term of the underlying loans. The model utilizes several assumptions, the most significant of which is loan prepayments, calculated using a three-month moving average of weekly prepayment data published by the Public Securities Association (PSA) and modeled against the serviced loan portfolio, and the discount rate to discount future cash flows. As of March 31, 2015, the prepayment assumption using the PSA model was 214, which translates into an anticipated prepayment rate of 12.83%. The discount rate is the quarterly average 10 year U.S. Treasury plus4.88%. Other assumptions include delinquency rates, foreclosure rates, servicing cost inflation, and annual unit loan cost. All assumptions are adjusted periodically to reflect current circumstances. Amortization of mortgage servicing rights, as well as write-offs due to prepayments of the related mortgage loans, are recorded as a charge against mortgage servicing fee income.For the three months ended March 31, 2015 and 2014, servicing rights capitalized totaled $64,000 and $81,000, respectively. Servicing rights amortized for the three months ended March 31, 2015 and 2014, were $104,000 and $114,000, respectively.  The fair value of servicing rights was $1,746,000, $2,088,000 and $2,114,000 at March 31, 2015, December 31, 2014 and March 31, 2014, respectively. The Bank serviced loans for others totaling $214,537,000, $214,086,000 and $211,725,000 at March 31, 2015, December 31, 2014, and March 31, 2014, respectively.
