Problem:
Kelly Inc's 5-year bonds yield 7.50% and 5-year T-bonds yield 4.50%. The real risk-free rate is r* = 2.5%, the default risk premium for Kelly's bonds is DRP = 0.40%, the liquidity premium on Kelly's bonds is LP = 2.6% versus zero on T-bonds, and the inflation premium (IP) is 1.5%.
What is the maturity risk premium?
