2 Calculating the present value of variable cash ﬂows

Your company has prepared forecasts for the development costs and operating proﬁts of the next generation of your product. Development costs for each of the next three years (Years 1 to

3)will be $50,000. Manufacturing equipment costing $100,000 will be purchased at the end of Year 3. Annual proﬁts for the ﬁve-year product life (from Year 4 to Year 8) are projected to be $80,000. The salvage value of the manufacturing equipment at the end of Year 8 is $20,000. Given a 12% discount rate, should your company proceed with the product development?
