Does anyone know where I can find the solution key for the Harvard Business Case "Globalizing the Cost of Capital and Capital Budgeting at AES" its very widely used and covers the following questions

Globalizing the Cost of Capital and Capital Budgeting at AES
1. Evaluate the capital budgeting method used historically by AES? What are the policy’s good and bad points?
2. If Venerus implements the proposed methodology, what would be the range of discount rates in use around the world?
3. Does this proposed methodology make sense as a way to do capital budgeting analysis?
4. What is the value of the Pakistan project using the cost of capital derived from the proposed methodology? What would
be the value of the project if it was located in the U.S.?
5. How does the adjusted cost of capital for the Pakistan project reflect the probabilities of real events? What does the
discount rate adjustment imply about expectations for the project because it is located in Pakistan and not the U.S.?
