Your bonds offer a higher coupon (5% vs. 4.5%) than treasuries of the same maturity, but sell for a lower price ($96.94 vs. $100). The reason is the credit spread. Your firm’s higher probability of default leads investors to demand a higher YTM on your debt. To provide a higher YTM, the purchase price for the debt must be lower. If your debt paid 5.4% coupons, it would sell at $100, the same as the treasuries. But to get that price, you would have to offer coupons that are 90 basis points higher than those on the treasuries—exactly enough to offset the credit spread.
