Navarre Energy Research specializes in developing and commercializing new products. It is organized Into two divisions, which are based on the products they produce. Canal Division is smaller, and the lives of the products it produces tend to be shorter than those produced by the larger Lake Division. Selected financial data for the past year are shown in the following table. Divisional investment is as of the beginning of the year. Navarre uses an 8 percent cost of capllal and beginning of the-year investment when computing ROI and residual income. Ignore income taxes. R\&D is assumed to have a three-year life in Canal Division and an eight-year life in Lake Division. All R\&D expenditures are spent at the beginning of the year. Assume there are no current llabilities and (unrealistically) that no R\&D imvestments had taken place before this yeat: The manager of the Canal Division complains that the calculatlon of EVA is unfair because a much longer life is assumed for the Lake Division in calculating EVA. The manager of Lake Division responds that EVA is supposed to reflect economic reality and that the reality is that RED investments in Lake Division do have a longer life. Required: 0. Assume that the economic life of RED investments in three years in the Canal Divilion What economic lile would the R\&D investments in the Lake Division have to make EVA in the two divisions egual
