Mumford and Sons Investment Company decides to invest $200,000 with the Avett Brothers. The deal they strike, as brokered by the Lumineers, is as follows:

1. They are allowed to invest 50% of their money on the first day of the deal (time 0), and the balance 1 year later (time 1).
2. However, due to the delayed investment, they wont get any revenue until year 2 at which time they will get $60,000, $60,000, $50,000 and $10,000 for each of years 2 through 5.
3. In addition to the revenue noted for those 4 years, they will have expenses of $30,000, $20,000, $20,000 and $10,000 for years 2 through 5 (they dont have any expenses in time 0 or year 1 other than the already described original investment).
4. They can deduct 100% of their operating expenses in year 2, 50% of their operating expenses in years 3 and 4, and none of their operating expenses in year 5.
5. At the end of the investment (time 5), they will get a return of their original investment but only $180,000. Any gain or loss on the investment is taxable, if a gain, or deductible, if a loss.
6. You cannot carry losses back or forward.
7. Their tax rate is 40%.
8. Their discount rate is 4%.
