D. Newcombe \& Associates is considering the introduction of a new product. Production of the new product requires an investment of $140,000 in equipment that has a five-year life. The equipment has no salvage value at the end of five years and will be depreciated on a straight-line basis. Newcombe's required return is 15% and the tax rate is 34%. The firm has made the following forecasts: a. Compute the NPV for the project, under both a base case and worst case scenario. b. Assume that all variables, except unit sales, take on their base case levels. If unit sales are at their worst case level, determine how sensitive OCF and NPV are to a change in unit sales
