An investor is considering a project that will generate free cash flow of $576,007 per year for 6 years. In addition to upfront costs, at the completion of the project at the end of year 6 there will be shut-down costs of $500,000. If the cost of capital is 5%, based on the NPV, at what upfront costs does this project cease to be worthwhile? Round to the nearest dollar, i.e. 1,000,000.
