Projections of amortization expense for mortgage servicing rights are based on existing asset balances and the existing interest rate environment as of March 31, 2016. Heartland's actual experience may be significantly different depending upon changes in mortgage interest rates and market conditions. Mortgage loans serviced for others were $4.11 billion and $4.06 billion as of March 31, 2016, and December 31, 2015, respectively. Custodial escrow balances maintained in connection with the mortgage loan servicing portfolio were approximately $25.0 million and $19.2 million as of March 31, 2016 and December 31, 2015, respectively. The fair value of Heartland's mortgage servicing rights was estimated at $38.9 million at March 31, 2016, and $40.9 million at December 31, 2015.

Heartland's mortgage servicing rights portfolio is comprised of loans serviced for the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation, and the Government National Mortgage Association. The servicing rights portfolio is separated into 15- and 30-year tranches.

The fair value of mortgage servicing rights is calculated based upon a discounted cash flow analysis. Cash flow assumptions, including prepayment speeds, servicing costs and escrow earnings are considered in the calculation. The average constant prepayment rate was 12.09% and 10.65% for the March 31, 2016, and December 31, 2015, valuations, respectively. The discount rate was 9.26% and 9.25% for the March 31, 2016, and December 31, 2015, valuations, respectively. The average capitalization rate for the first three months of 2016 ranged from 88 to 135 basis points compared to the range of 65 to 138 basis points for 2015. Fees collected for the servicing of mortgage loans for others were $2.9 million and $2.5 million for the three months ended March 31, 2016, and March 31, 2015, respectively.

The following table summarizes, in thousands, the changes in capitalized mortgage servicing rights for the three months ended March 31, 2016, and March 31, 2015:

Fees collected for the servicing of commercial loans for others were $80,000 for the period ended March 31, 2016.

The fair value of each commercial servicing rights portfolio is calculated based upon a discounted cash flow analysis. Cash flow assumptions, including prepayment speeds and servicing costs, are considered in the calculation. The range of average constant prepayment rates for the portfolio valuations for the first three months of 2016 was 7.14% to 8.10% compared to 7.33% to 8.10% as of December 31, 2015. The discount rate range was 11.74% to 13.49% for the March 31, 2016, valuations compared to 12.35% to 13.49% for the December 31, 2015, valuations. The capitalization rate for 2016 ranged from 3.10 to 4.45 basis points compared to 1.80 to 4.45 basis points for 2015. The total fair value of Heartland's commercial servicing rights was estimated at $4.9 million as of March 31, 2016.

The following table summarizes, in thousands, the changes in capitalized commercial servicing rights for the three months ended March 31, 2016, and March 31, 2015:



	2016			2015
Balance at January 1	$	4,611		$	—

Commercial servicing rights, net to servicing portfolio	2.35		%	2.87		%

Mortgage and commercial servicing rights are initially recorded at fair value in net gains on sale of loans held for sale when they are acquired through loan sales. Fair value is based on market prices for comparable servicing contracts, when available, or based on a valuation model that calculates the present value of estimated future net servicing income.

Mortgage and commercial servicing rights are subsequently measured using the amortization method, which requires the asset to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Servicing rights are evaluated for impairment based upon the fair value of the assets as compared to the carrying amount. Impairment is recognized through a valuation allowance for specific tranches to the extent that fair value is less than carrying amount. At March 31, 2016, and December 31, 2015, no valuation allowance was required for any of Heartland's servicing rights.
