Currently working on the Stryker Corporation Case to determine if Option #3, in-sourcing their own PCB's, is a viable project. Must compute the incremental cash flows from the theoretical inception of the project in 2004 through 2009, and use these numbers to calculate the NPV, IRR and payback period. Requesting an excel spreadsheet with a walk through of the FCF calculation and the rest of the numbers and a concise explanation of why the chosen numbers from the Historical Figures and/or the Case Proposal were used.
