Note 6

Mortgage Servicing Rights

The Company serviced $233.6 billion of residential mortgage loans for others at March 31, 2017, and $232.6 billion at December 31, 2016, which include subserviced mortgages with no corresponding MSRs asset. The net impact included in mortgage banking revenue of fair value changes of MSRs due to changes in valuation assumptions and derivatives used to economically hedge MSRs were net gains of $12 million and net losses of $22 million for the three months ended March 31, 2017 and 2016, respectively. Loan servicing and ancillary fees, not including valuation changes, included in mortgage banking revenue, were $192 million and $184 million for the three months ended March 31, 2017 and 2016, respectively.

Changes in fair value of capitalized MSRs are summarized as follows:


Three Months Ended March 31,
(Dollars in Millions)	2017			2016
Balance at beginning of period	$	2,591		$	2,512
Rights purchased		2			8
Rights capitalized		122			99
Changes in fair value of MSRs
Due to fluctuations in market interest rates (a)		20			(301	)
Due to revised assumptions or models (b)		12			–
Other changes in fair value (c)		(105	)		(96	)
Balance at end of period	$	2,642		$	2,222

(a)

Includes changes in MSR value associated with changes in market interest rates, including estimated prepayment rates and anticipated earnings on escrow deposits.

(b)

Includes changes in MSR value not caused by changes in market interest rates, such as changes in cost to service, ancillary income and option adjusted spread, as well as the impact of any model changes.

(c)

Primarily represents changes due to realization of expected cash flows over time (decay).

The estimated sensitivity to changes in interest rates of the fair value of the MSRs portfolio and the related derivative instruments was as follows:

The fair value of MSRs and their sensitivity to changes in interest rates is influenced by the mix of the servicing portfolio and characteristics of each segment of the portfolio. The Company’s servicing portfolio consists of the distinct portfolios of government-insured mortgages, conventional mortgages and Housing Finance Agency (“HFA”) mortgages. The servicing portfolios are predominantly comprised of fixed-rate agency loans with limited adjustable-rate or jumbo mortgage loans. The HFA division specializes in servicing loans made under state and local housing authority programs. These programs provide mortgages to low-income and moderate-income borrowers and are generally government-insured programs with a favorable rate subsidy, down payment and/or closing cost assistance.

A summary of the Company’s MSRs and related characteristics by portfolio was as follows:

(a)

Represents principal balance of mortgages having corresponding MSR asset.

(b)

Calculated as fair value divided by the servicing portfolio.

(c)

Represents loans sold primarily to GSEs.

(d)

Option adjusted spread is the incremental spread added to the risk-free rate to reflect optionality and other risk inherent in the MSRs.
