Exercise $3\mathrm{.}1($Solve on A&C$,$ Im not familiar with this topic so please show as many steps as possible.$)$

You need to create a portfolio to cover the following stream of

liabilities for the next six future dates:

You may purchase the bonds in Table $3\mathrm{.}2.$

The term structure of risk$-$free interest rates is:

$($a$)$ Formulate a linear programming model to find the lowest$-$cost long$-$only

dedicated portfolio that covers the stream of liabilities with the bonds above.

Assume surplus balances can be carried from one date to the next but earn

no interest. What is the cost of your portfolio? What is the composition of

your portfolio?

$($c$)$ Use the linear programming sensitivity information from part $($a$)$ to deter$-$

mine the implied term structure of interest rates.
