Compute the WACC for the Hughes acquisition.

In 1985, General Motors (GM) was evaluating the acquisition of Hughes Aircraft Corporation. Recognizing that the appropriate WACC for discounting the projected cash flows for Hughes was different from General Motors’
WACC, GM assumed that Hughes was of approximately the same risk as Lockheed or Northrop, which had low-risk defense contracts and products that were similar to those of Hughes. Specifically, assume the Hamada model of debt interest tax shields and the inputs in the table at right.AppendixLO1
