An analyst is preparing a project evaluation for a proposedexpansion into a new line of business. The following are expected cash flows for the project for the next six years: T$=0$ Y$1$ Y$2$ Y$3$ Y$4$ Y$5$ Y$6$ Expected Cash Flows $($$Ms$)-2,0005007107809901210-1,605$ The initial investment of $$2\mathrm{.}0$B will be invested immediately. The cash flows in year $6$ are reclamation costs $($the project involves destruction of wilderness $$ environmental regulation requires cleanup of the site at the end of the project, returning the land back to its original state $$ this costs just over $$1\mathrm{.}6$B$).$ You may assume that all yearly cash flows occur at year end. The appropriate discount rate given the risk of the project is $12\mathrm{.}0\%.$ Using the NPV and IRR methods, should we invest in this new project?
