Exercise 13-28 Economic Value Added (EVA); (LO 13-2) Golden Gate Construction Associates, a real estate developer and building contractor in San Francisco, has two sources of long-term capital: debt and equity. The cost to Golden Gate of issuing debt is the after-tax cost ofthe interest payments on the debt, taking into account the fact that the interest payments are tax deductible. The cost of Golden Gate's equity capital is the investment opportunity rate of Golden Gate's investors, that is, the rate they could earn on investments of similar risk to that of investing in Golden Gate Construction Associates. The interest rate on Golden Gate's $64 million of long-term debt is 7 percent, and the company's tax rate is 30 percent. The cost of Golden Gate's equity capital is 10 percent. Moreover, the market value (and book value) of Golden Gate's equity is $85 million. The company has two divisions: the real estate division and the construction division. The divisions' total assets, current liabilities, and before-tax operating income for the most recent year are as follows: BeforeTax Current Operating Division Total Assets Liabilities Income Real estate $99,000,000 $6,000,000 $20,600,000 Construction 65,800,000 3,300,000 18,700,000
