A $4 million investment today, in a project to last 10 years, is believed to result in the following incremental cash flows:

• annual increase in sales of $2,100,000
• operating expenses will be 50% of sales
• there is no NWC investment associated with this project
• assets purchased for this project are depreciated to zero value using straight-line over the project's complete life
• market value of assets at end of life are expected to be $0
• firm's marginal tax rate is 32%
• required return on the project is 14% compounded annually

What is the NPV of this project?

What is the IRR of the above project? Note that it has conventional cash flows and positive NPV, therefore IRR must be greater than 0.16

.What level of incremental sales would cause the above project to break-even (have NPV=$0)?
