Mortgage Servicing Rights

The Company’s portfolio of residential mortgage loans serviced for third parties was $3.1 billion as of March 31, 2014 and December 31, 2013.  Generally, the Company’s residential mortgage loans sold to third parties are sold on a non-recourse basis.  The Company’s mortgage servicing activities include collecting principal, interest, and escrow payments from borrowers; making tax and insurance payments on behalf of borrowers; monitoring delinquencies and executing foreclosure proceedings; and accounting for and remitting principal and interest payments to investors.  Servicing income, including late and ancillary fees, was $2.0 million for the three months ended March 31, 2014 and 2013.  Servicing income is recorded as a component of mortgage banking income in the Company’s consolidated statements of income.  The Company’s residential mortgage investor loan servicing portfolio is primarily comprised of fixed rate loans concentrated in Hawaii.

For the three months ended March 31, 2014 and 2013, the change in the carrying value of the Company’s mortgage servicing rights accounted for under the fair value measurement method was as follows:

The key data and assumptions used in estimating the fair value of the Company’s mortgage servicing rights as of March 31, 2014 and December 31, 2013 were as follows:

A sensitivity analysis of the Company’s fair value of mortgage servicing rights to changes in certain key assumptions as of March 31, 2014 and December 31, 2013 is presented in the following table.

This analysis generally cannot be extrapolated because the relationship of a change in one key assumption to the change in the fair value of the Company’s mortgage servicing rights usually is not linear.  Also, the effect of changing one key assumption without changing other assumptions is not realistic.
