Company A, a British manufacturer, wishes to borrow U.S. dollars at a fixed rate of interest. Company B, a U.S. multinational, wishes to borrow sterling at a fixed rate of interest. They have been quoted the following rates per annum:
$$
\begin{array}{lcc}
\hline & \text { Sterling } & \text { U.S. Dollars } \\
\hline \text { Company A } & 11.0 \% & 7.0 \% \\
\text { Company B } & 10.6 \% & 6.2 \% \\
\hline
\end{array}
$$
(Rates have been adjusted for differential tax effects.) Design a swap that will net a bank, acting as intermediary, 10 basis points per annum and that will produce a gain of 15 basis points per annum for each of the two companies.
