Alternative Capital Investments The investment committee of Sentry Insurance Co. is evaluating two projects, office expansion and upgrade to computer servers. The projects have different useful lives, but each requires an investment of $770,000. The estimated net cash flows from each project are as follows: The committee has selected a rate of 15% for purposes of net present value analysis. It also estimates that the residual value at the end of each project's useful life is $0, but at the end of the fourth year, the office expansion's residual value would be $269,000. Present Value of an Annuity of $1 at Compound Interest Dracent Valse of an Annuity of $1 at Comnnund Tntaract Required: If required, use the minus sign to indicate a negative net present value. 1. For each project, compute the net present value. Use the present value of an annuity of $1 table above. Ignore the unequal lives of the projects. If required, round to the nearest dollar. 2. For each project, compute the net present value, assuming that the office expansion is adjusted to a four-year life for purposes of analysis. Use the present value of $1 table above. If required, round to the nearest dollar
