Bidding for Antamina Case Solution

Case Solution

In June 1996, managers of the global mining firm RTZ-CRA were thinking about putting forward an offer to purchase the Antamina copper and zinc mine located in Peru. The Antamina project is proposed for selling via an auction as a step in the privatization process of Peru's government mining company. RTZ-CRA has to decide what is the value of the mine and also determine how much to offer at the near bidding process. The bidding policy established by state of Peru holds that each company’s offer must comprise of two parts: an immediate cash figure and a figure for the amount that the proposer would invest to build the assets if development is guaranteed after additional exploration is finished.

Questions Covered

1.     In what way is the development of a copper mine like Antamina a real option?  In what way is the bidding structure put in place by the Peruvian government an option?  What is the correspondence between these real options and financial options?  What other real options does the owner of the Antamina have?

2.     Conceptually, how would you build a real options model to value the Antamina project?  What data and assumptions would you need?  What would be the key assumptions and limitations of the model?  Review the model suggested in the reading on the basis of your reactions to these questions.

3.     Consider the bids that should be made for the property under these three different sets of auction procedures:

If the winning bidder was legally forced to develop Antamina after completing the exploration phase, and was required to pay the Peruvian government up-front for this project, what is the most they would be willing to bid?

If the winning bidder could choose whether or not to develop Antamina at the end of two years, but was required to pay the Peruvian government a single fee up-front for the right to develop the project, what is the most they would be willing to pay?  Under this alternative, there is no investment commitment or penalty; the firm merely pays the government up front, and has the right to develop at the end of two years.  If they don’t develop at year two, they lose the right to develop the field.

Under the current bidding rules, the winning bidder states both an initial cash payment as well as an investment commitment that is paid only if they choose to develop the field.  Bids are developed by summing up-front amount and 30% of the investment commitment.  If you proceed with development, but fail to spend the full investment commitment, the Peruvian government will fine you 30% of the difference.  What is the most you would be willing to bid under these rules?  How would you trade-off these two components of the bid?

4.     What are the incentives brought about by the different auction rules?  Do the rules seem to meet what you perceive to be the goals of the Peruvian government?
