A company's 5-year bonds are yielding 8.4% per year. Treasury bonds with the same maturity are yielding 5.35% per year, and the real risk-free rate (r*) is 2.9%. The average inflation premium is 2.05%, and the maturity risk premium is estimated to be 0.1 x (t - 1)%, where t = number of years to maturity. If the liquidity premium is 0.9%, what is the default risk premium on the corporate bonds? Round your answer to two decimal places.
