Significant Unobservable Inputs Used in Fair Value Measurement

The tables below present information about the significant unobservable inputs used in the fair value measurement of the Company’s Servicing Related Assets classified as Level 3 fair value assets as of the dates indicated (dollars in thousands):

Fair Value Measurements

As of December 31, 2018

	Fair Value		Valuation Technique	Unobservable Input (A)	Range			Weighted Average
MSRs
Conventional	$	254,691	Discounted cash flow	Constant prepayment speed		4.5% - 20.6	%		9.1	%
				Uncollected payments		0.5% - 11.7	%		0.9	%
				Discount rate					9.3	%
				Annual cost to service, per loan				$	70
Government	$	40,216	Discounted cash flow	Constant prepayment speed		6.3% - 17.9	%		8.9	%
				Uncollected payments		3.1% - 12.4	%		4.2	%
				Discount rate					12.0	%
				Annual cost to service, per loan				$	111
TOTAL	$	294,907

As of December 31, 2017

	Fair Value		Valuation Technique	Unobservable Input(A)	Range			Weighted Average
MSRs
Conventional	$	82,150	Discounted cash flow	Constant prepayment speed		6.5% - 23.5	%		10.5	%
				Uncollected payments		0.2% - 1.8	%		0.8	%
				Discount rate					9.3	%
				Annual cost to service, per loan				$	70
Government	$	40,656	Discounted cash flow	Constant prepayment speed		6.0% - 14.2	%		8.1	%
				Uncollected payments		0.4% - 5.2	%		3.3	%
				Discount rate					12.0	%
				Annual cost to service, per loan				$	96
TOTAL	$	122,806

(A) Significant increases (decreases) in any of the inputs in isolation may result in significantly lower (higher) fair value measurements. A change in the assumption used for discount rates may be accompanied by a directionally similar change in the assumption used for the probability of uncollected payments and a directionally opposite change in the assumption used for prepayment rates.
