Changes in Fair Value of Capitalized MSRs

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

Three Months Ended March 31 (Dollars in Millions)	2015			2014
Balance at beginning of period	$	2,338		$	2,680
Rights purchased		6			1
Rights capitalized		145			84
Changes in fair value of MSRs
Due to fluctuations in market interest rates (a)		(131	)		(76	)
Due to revised assumptions or models (b)		—			12
Other changes in fair value (c)		(108	)		(83	)
Balance at end of period	$	2,250		$	2,618

(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 discount rate, as well as the impact of any model changes.

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

Sensitivity to Changes in Market Interest Rates to Fair Value of MSRs Portfolio and Related Derivative Instruments

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