	Manager A	Manager B
Capital	$150,000,000	$590,000,000
VAR	$7,500,000	$21,000,000
Profit	$2,000,000	$7,000,000

A) Manager A because they had a higher return on capital.

B) Manager A because they used less VAR.

C) Manager B because they had a higher profit.

D) Manager B because their return is higher in a risk budgeting context.

Answer and Explanation

Using risk budgeting in enterprise risk management, we would divide the profit by the VAR allowed to generate a risk-adjusted performance measure. For manager A it is 26.7% (2,000,000/7,500,000). For Manager B it is 33.3% (7,000,000/21,000,000). Thus Manager B has better risk-adjusted performance. Note that the return on capital for each manager tells a different story. For manager A it is 1.3% (2,000,000/150,000,000) and it is 1.2% (7,000,000/590,000,000) for Manager B. So although the percentage return generated is higher for Manager A, we would conclude that Manager B has better performance when risk is considered.

For a firm that uses enterprise risk management, what type of limit should be used to ensure firm diversification?

A) Liquidity limit.

B) Risk factor limit.

C) Position limit.

D) Performance stopout.

Answer and Explanation

A position limit places a dollar nominal cap on a given position. By placing a maximum dollar amount on each position, the firm will diversify its capital across a greater number of sectors. A liquidity limit is a position limit that is based on trading volume so that liquidity risk is minimized. A performance stopout sets a dollar limit for losses over a specified time period. Risk factor limits restrict the exposure of the portfolio to individual risk factors.
