　　3.A bank has an outstanding trade with one of its counterparties with an exposure of $500,000 and a recovery rate of 70%. The bank estimated that there is a 2% probability that the counterparty， will default on its obligations. What is the bank's expected loss?
　　A. $3,000
　　B. $7,000
　　C. $10,000
　　D. $150,000
　　Answer:
　　1.C
　　The company with the highest recovery rate will be the company with the most tangible assets that can be valued in the event of default. Utilities, for example, have high recovery rates because they have large amounts oftangible assets, such as generating plants. Ofthe four choices - internet merchant, hedge fund, asset intensive manufacturing company and commodity trader - the asset intensive manufacturer would have the most tangible assets. Thus, choice 'C' is the correct choice.
　　2.A
　　A decrease in interest rates increases the probability of prepayments, so less interest will be collected over the life of securities. A decrease in rates will cause a smaller increase in POs value because the cash tlows are being discounted at a lower rate. However, the prepayment effect typicaUy dominates when rates are below the mortgage rates in the pool. Thus, 105 are likely to uecrease in value, and POs will increase in value.
　　3.A
　　At a recovery rate of 70%, the recovery amount is $500,000XO.70 = $350,000
　　The loss given default (LGD) is $500,000 - $350,000 = $150,000
　　Expected loss is (probability of defaultXLGD) = 0.02X $150,000 = $3,000
