In the $1980$s$,$ Banks Trust developed index currency option notes $($ICONs$).$ These are bonds in which the amount received by the holder at maturity varies with a foreign exchange rate. One example was its trade with the Long Term Credit Bank of Japan. The ICON specified

that if the yen$-$US dollar exchange rate, $S_T,$ is greater than $169$ yen per dollar at maturity $($in $1995),$ the holder of the bond receives $$1,000.$ If it is less than $169$ yen per dollar, the amount received by the holder of the bond is

$1000-$max$\{1000(\frac{169}{S_T}-1),0\}$

When the exchange rate is below $84\mathrm{.}5$ yen$/$USD$,$ nothing is received by the holder at maturity. Show that this ICON is a combination of a regular bond and two options.
