Report to the Congress on the Effect of Capital Rules on Mortgage Servicing Assets

Appendix

This table displays selected summary statistics from BHCs' forecasts of the changes in their MSA valuations in a variety of stress scenarios. The forecasts are based on the characteristics of the BHCs' servicing portfolios as of the end of 2015. In this calculation, the first step is to calculate the percent change in each BHC's MSA valuation in each of the stress scenarios. The second step is to calculate the average, median, standard deviation, and interquartile range of these percent changes across BHCs.
