(A) (B) (C) (D) (E)
Bond
Value
(USD)
Modified
Duration
(BxC) (D/B)
1 4,000,000 7.5 30,000,000
2 2,000,000 1.6 3,200,000
3 3,000,000 6.0 18,000,000
4 1,000,000 1.3 1,300,000
SUM 10,000,000 52,500,000 5.25
The portfolio modified duration is 5.25. This is obtained by multiplying the value of each bond by the modified
duration(s), then taking the sum of these products, and dividing it by the value of the total bond portfolio.
The change in the value of the portfolio will be -10,000,000 x 5.25 x 0.1% = -52,500
