In each of the simulation’s scenarios, net present value and internal rate of return were used to determine the optimal choice pertaining to outsourcing or investing in a new plant for its card operations. Outsourced production issues arose in the second scenario introducing debt-equity mix in the evaluations. A drop in long-term interest rates made it more lucrative for InnoVista to invest in an additional plant with a debt-equity mix of 60% - 40%. The third scenario involved evaluating the criterion to increase production. Maintaining the same debt-equity mix as the second scenario, upping manufacturing to 900,000 units, and adding an additional shift proved to be the most optimal approach for InnoVista to meet consumer demands for its Cracker Pop cards as it resulted in a low cost per capital while also producing a high NPV.
Aside from NPV and IRR, companies also use the payback period to evaluate possible investments. The payback period estimates the length of time required to recover the cost of an investment and addresses how desirable an investment is over the long-term. The payback method does have disadvantages in that it ignores time value of money principles and fails to recognize the profitability and risk of an investment. “Because of these reasons, other methods of capital budgeting like net present value and internal rate of return are generally preferred” (Answers Corporation, 2007).
Although net present value (NPV) is a preferred criterion in
