The fair value of the construction advances approximates book value and the sales price of these loans is estimated based on construction completed.

[4] The fair values are based on changes in GSE mortgage backed bond prices, and additionally for IRLCs, pull through rates.

[5] The fair value approximates book value based on current market rates and the revolving nature of the instruments.

[7] The fair value of the mortgage servicing rights is based on the present value of expected net cash flows related to servicing these loans.
