A bicycle manufacturer currently produces $300,000$ units per year and expects output levels to remain steady in the future. It buys one chain per unit from an outside supplier at the price of $$2$ per chain. The plant manager believes that it would be cheaper to make these chains rather than buy them. Direct in$-$house production costs are estimated to be only $$1\mathrm{.}50$ per chain. The necessary equipment would cost $$250,000$ and would be obsolete after $10$ years. The investment could be depreciated to zero for tax purposes using a $10-$year straight$-$line depreciation schedule. The plant manager estimates that the operation would require $$50,000$ of inventory and other working capital up front. This inventory and other working capital can be sold at the end of the $10$ years for $$50,000.$ Expected proceeds from scrapping the machinery after $10$ years are $$20,000.$ The company$$s marginal tax rate is $35\%,$ the appropriate discount rate for all cashflows associated with the above investment is $15\%,$ and the project will be $100\%$ equity financed. $2$ What is the NPV of the decision to produce the chains in$-$house instead of purchasing them from a supplier? Assume that the capital expenditure and working capital investment would occur immediately, and all other cashflows occur at the end of the relevant year
