3. Calculating interest rates The real risk-free rate (**) is 2.8% and is expected to remain constant. Inflation is expected to be 3% per year for each of the next two years and 2% thereafter. The maturity risk premium (MRP) is determined from the formula: 0.1(t-1)%, where t is the security's maturity. The liquidity premium (LP) on all Berth Construction Inc.'s bonds is 1.05%. The following table shows the current relationship between bond ratings and default risk premiums (DRP): Default Risk Premium Rating U.S. Treasury AAA AA BBB 0.60% 0.80% 1.05% 1.45% Berth Construction Inc. Issues thirteen-year, AA-rated bonds. What is the yield on one of these bonds? Disregard cross-product terms; that is, if averaging is required, use the arithmetic average. 6.80% 5.85% 8.00% 6.95% Based on your understanding of the determinants of interest rates, if everything else remains the same, which of the following will be true? The yield on an AAA-rated bond will be higher than the yield on a BB-rated bond. In theory, the yield on a bond with a longer maturity will be higher than the yield on a bond with a shorter maturity
