r_0 = 1.5% |
r_2,HL = 3.2% |

r_2,LL = 2.2% |
| Face value | 1000 |

| T = 0 | T = 1 | T=2 |
| 3% annual coupon of $1000 par value | ||||||
| So , maturity value = 1000 + (3% *1000) = 1030 | ||||||
| Value at T=2 | = | Maturity value at t=3 discounted + coupon int | ||||
| fuu | (1038/1.05) + 38 | = | 1026.571 | |||
| fud | (1038/1.032) + 38 | = | 1043.814 | |||
| fdd | (1038/1.022) + 38 | = | 1053.656 | |||
| Value at T=1 | = | Maturity value at Average of t=2 discounted + coupon int | ||||
| fu | = | 0.5*(1026.571/1.037)+ 38 + 0.5* (1043.814/1.037)+38 | = | 1074.2569 | ||
| fd | = | 0.5(1043.814/1.029)+38 + 0.5(1053.656/1.029)+38 | = | 1095.1788 | ||
| Value at T=0 | Maturity value at Average of t=1 discounted + coupon int | |||||
| Value | = | 0.5[(1074.2569/1.015)+(1095.1788/1.015)] | 1068.6875 |
