FRM Part II · FRM Exam Part II · Risk Capital Attribution and Risk-Adjusted Performance Measurement
A bank evaluates two loan portfolios using RAROC. Portfolio X: risk-adjusted return $9 million, economic capital $60 million. Portfolio Y: risk-adjusted return $12 million, economic capital $100 million. The bank's cost of equity is 13%. Which statement is correct?
Portfolio X has RAROC of 15% and exceeds the 13% cost of equity, so it creates value; Portfolio Y has 12% and falls short, so it destroys value. Y's larger dollar return is misleading because it uses much more capital.
- AX has RAROC 15% and creates value; Y has RAROC 12% and destroys valueCorrect
- BX has RAROC 12% and destroys value; Y has RAROC 15% and creates value
- CBoth create value because returns are positive
- DBoth destroy value because RAROC is below 20%
Explanation
X: 9/60 = 15% > 13%, creating value. Y: 12/100 = 12% < 13%, destroying value. Y has higher absolute return but lower RAROC, so absolute profit is misleading.
