a. We need to calculate the PV of the annual interest of $30, i.e., $1000 x 3%, for the next 8 years, and the principal payment of $1000 at the end of year 8, at the rate of 2%, which is the current discount rate. That will give us the value of this bond now. I can sell this bond for $1073.25 now
| Time | CF | PV = CF / 1.02^time |
| 1 | 30.00 | 29.41 |
| 2 | 30.00 | 28.84 |
| 3 | 30.00 | 28.27 |
| 4 | 30.00 | 27.72 |
| 5 | 30.00 | 27.17 |
| 6 | 30.00 | 26.64 |
| 7 | 30.00 | 26.12 |
| 8 | 1,030.00 | 879.10 |
| Total | 1,073.25 |
b. We need to calculate an IRR for the $1000 of investment 2 years, ago, 2 interest payments, and the selling price now. Annualized HPR is 6.55% p.a.
| Time | CF |
| 0 | -1,000.00 |
| 1 | 30.00 |
| 2 | 1,103.25 |
| IRR | 6.55% |
