Dyson Inc. currently finances with 20.0% debt (i.e., wd = 20%), but its new CFO is considering changing the capital structure so wd = 60.0% by issuing additional bonds and using the proceeds to repurchase and retire common shares so the percentage of common equity in the capital structure (wc) = 1 – wd.  Given the data shown below, by how much would this recapitalization change the firm's cost of equity? (Hint: You must unlever the current beta and then use the unlevered beta to solve the problem.)

Risk-free rate, rRF                            5.00%              Tax rate, T            40%

Market risk premium, RPM 6.00%              Current wd    20%

Current beta, bL1                              1.15                 Target wd            60%
