Company XYZ generates annual cash-flows equal to USD 1 million, in a perpetual way. For simplicity, we assume that the firm cost of equity and cost of debt are both equal to 10 percent, and the firm has a (perpetual) debt level equal to USD 1 million. Company XYZ is incorporated in a country that currently has a corporate tax of 0 percent. It follows that the market value of the assets of Company XYZ is USD 10 million. Suppose that the country announces unexpectedly that the marginal corporate tax rate is now equal to 10 percent. What is the change in the total market value of the assets of Company XYZ associated to the announcement?
