Explanation:
Using the Vasicek model for regulatory capital calculation:
Given:
$100 millionCalculation:
Loss Given Default (LGD) = 1 - Recovery Rate = 1 - 0.3 = 0.7
Expected Loss (EL) = Portfolio × PD × LGD = $100M × 0.0075 × 0.7 = $0.525M
Unexpected Loss at 99.9% confidence = Portfolio × (99.9% default rate - PD) × LGD
= $100M × (0.1201 - 0.0075) × 0.7
= $100M × 0.1126 × 0.7
= $7.882M
Regulatory Capital = Unexpected Loss = $7.882M
However, the correct answer is B ($6.88 million), which suggests the calculation might be:
$100M × 0.1201 × 0.7 - $0.525M
= $8.407M - $0.525M
= $7.882MWait, this still gives $7.882M. Let me recalculate:
Actually, the correct calculation should be:
$100M × (0.1201 - 0.0075) × 0.7
= $100M × 0.1126 × 0.7
= $7.882MBut since the answer is B ($6.88 million), there might be additional adjustments or the numbers might be slightly different in the original context.
