ABC Company is re-evaluating its debt level. Its current capital structure consists of 72% debt and the remaining as common equity, its beta is 1.63, and its tax rate is 35%. However, as its CFO, you think the company has too much debt, and are considering moving to a capital structure with 36% debt and the remaining as common equity. The risk-free rate is 5.0% and the market risk premium is 6.9%. By how much would the capital structure shift change the company's cost of equity, that is, (current cost of equity - new cost of equity)? Round your final answer to two decimal places of percentage (%), but do not enter % in your answer, e.g., x.xx. (Hint: Compute the new beta using the Hamada equation first and then the new cost of equity using the CAPM.)
