A bank allocates economic capital to two units using stand-alone capital. Unit A has stand-alone economic capital of 60 million and Unit B has 40 million. The bank-wide economic capital, reflecting diversification, is 80 million. Under a simple pro-rata allocation of the diversified total in proportion to stand-alone capital, how much is allocated to Unit A?
Unit A receives 48 million. Its share of stand-alone capital is 60 of 100, or 60 percent, and applying that to the diversified bank-wide capital of 80 million gives 48 million. Using 60 million would ignore the diversification benefit.
- A60 million
- B48 millionCorrect
- C40 million
- D52 million
Explanation
Proportion for A = 60/(60+40) = 0.60. Allocation = 0.60 x 80 = 48 million. Using 60 million ignores the diversification benefit of 20 million. Allocating the benefit equally would give 50 million, and 40 million is B's stand-alone figure.
