Activity for Residential First Mortgage MSRs
The table below presents activity for residential first-lien MSRs for 2011 and 2010. Commercial and residential reverse MSRs, which are carried at the lower of carrying or market value and accounted for using the amortization method, totaled $132 million and $277 million at December 31, 2011 and 2010, and are not included in the tables in this Note.

(1) 
Represents the change in the market value of the MSR asset due to the impact of customer payments received during the period.
(2) 
These amounts reflect changes in the modeled MSR fair value largely due to observed changes in interest rates, volatility, spreads and the shape of the forward swap curve.
(3) 
These amounts reflect periodic adjustments to the valuation model as well as changes in certain cash flow assumptions such as costs to service and ancillary income per loan.

Assumption for Fair Value of MSRs
The significant economic assumptions used in determining the fair value of MSRs at December 31, 2011 and 2010 are presented below.

Sensitivity of the Weighted-Average Lives and Fair Values of MSRs
The table below presents the sensitivity of the weighted-average lives and fair value of MSRs to changes in modeled assumptions. These sensitivities are hypothetical and should be used with caution. As the amounts indicate, changes in fair value based on variations in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of MSRs that continue to be held by the Corporation is calculated without changing any other assumption. In reality, changes in one factor may result in changes in another, which might magnify or counteract the sensitivities. The below sensitivities do not reflect any hedge strategies that may be undertaken to mitigate such risk.
