Hartford Mining has 80 million shares that are currently trading for $3 per share and $100 million worth of debt. The debt is risk free and has an interest rate of 2%, and the expected return of Hartford stock is 15%. Suppose a mining strike causes the price of Hartford stock to fall 20% to $2.40 per share. The value of the risk-free debt is unchanged. Assuming there are no taxes and the risk (unlevered bota) of Hartford's assets is unchanged, what happens to Hartford's equity cost of capital? Equity cost of capital is [%. (Round to two decimal places.)
