JT Engineering is considering a project with a $$400,000$ investment that will generate $$640,000$ net cash flows over five years. JT has calculated the NPV of this investment to be $$61,412$ at a $12\%$ discount rate. Unfortunately, this project is riskier than most of JT$$s other projects, which the company did not take into consideration when completing their NPV analysis. What error did JT make as a result and what impact did it have on the NPV$?$
