Combined federal and state tax rate 40%

Problem 13.6 WestGas Conveyance, Inc.
A London bank advises WestGas that U.S. dollars could be raised in Europe at the following costs, also in multiples of $20 million, while maintaining
the 50/50 capital structure.
b. If WestGAs plans an expansion of only $60 million, how should that expansion be financed? What will be the weighted average cost of capital for
the expansion?
Each increment of cost would be influenced by the total amount of capital raised. That is, if WestGas first borrowed $20 million in the European market
at 6% and matched this with an additional $20 million of equity, additional debt beyond this amount would cost 12% in the United States and 10% in
Europe. The same relationship holds for equity financing.
a. Calculate the lowest average cost of capital for each increment of $40 million of new capital, where WestGas raises $20 million in the equity market
and an additional $20 in the debt market at the same time.
WestGas Conveyance, Inc., is a large U.S. natural gas pipeline company that wants to raise $120 million to finance expansion. WestGas wants a capital
structure that is 50% debt and 50% equity. Its corporate combined federal and state income tax rate is 40%. WestGas finds that it can finance in the
domestic U.S. capital market at the rates listed below. Both debt and equity would have to be sold in multiples of $20 million, and these cost figures
show the component costs, each, of debt and equity if raised half by equity and half by debt.
