Saddle River Operating Company? (SROC) is a? Dallas-based independent oil and gas firm. In the? past, the? firm's managers have used a single? firm-wide cost of capital of 14 percent to evaluate new investments.?

E&P division were to borrow based on its projects? alone, the cost of debt would probably be 9.1 ?percent, and the pipeline division could borrow at 5.6 percent. You may assume these costs of debt are after any flotation costs the firm might incur. bullet The? risk-free rate of interest on? long-term U.S. Treasury bonds is currently 3.7 ?percent, and the? market-risk premium has averaged 5.9 percent over the past several years. bullet The?
