Answer: 1-year VaR based on loss distributions for each of the 21 combinations of business lines and each of the Basel operational risk types
B is correct. The AMA requires banks to consider every combination of 8 specified business lines and the 7 categories of operational risk identified by the Basel Committee. For each of the 56 combinations, banks have to estimate the 99.9 percent of the 1-year loss. These estimates are then aggregated to determine total operational risk capital, which is set equal to the 99.9 percentile of the loss distribution minus the expected operational loss, or the 99.9% VaR. Since Bank Theta has 3 of the 8 business lines, its operational risk capital would therefore be 1-year, 99.9% VaR based on loss distributions for each of the 21 (= 7 * 3) combinations of business line and operational risk type.
