Example: quanto caplet.

quanto caplet is a contract that pays at $T_{2}$ an amount proportional toMATH units of dollar. The MATH is the $\U{a3}$-Libor. Hence, from the $ point of view the value of the contract isMATH The MATH is a martingale with respect to the MATH-measure:MATH We wish to transform to the MATH-measure. Hence, we use the ( Change of numeraire recipe)MATH The combination under the log-sign is the forward exchange rate ( Forward exchange rate) for the time $T$ as observed at $t$MATH Therefore,MATH Similarly to the previous section we now construct a martingale combination and observe that the price of the contract is given by the Black-Scholes type formula.
