I have opened the group case for you to complete. You can find the details of the case in the drop down menu for E Centennial. Please note that for calculation purposes use $11\%$ as the cost of capital & $30\%$ as the company's tax rate.

Essentially based on the facts of the case you will need to make a determination whether to refurbish the existing finisher or purchase a new one. That will require you to identify all relevant cash flows and perform a NPV calculation. I recommend you net the cash flows so that you have only one NPV not multiple ones.

You should submit your NPV calculations plus a one page summary that supports your NPV calculations. This should include what other factors you took into consideration when choosing which alternative was best.
