8. Calculating interest rates The real risk-free rate (r*) 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 Moq Computer Corp.'s bonds is 0.55%. The following table shows the current relationship between bond ratings and default risk premiums (DRP): Rating Default Risk Premium U.S. Treasury AAA 0.60% AA 0.80% 1.05% BBB 1.45% Moq Computer Corp. issues 15-year, AA-rated bonds.
