Change of numéraire is a powerful technique for the pricing of options under random discount factors by the use of forward measures.

Girsanov's Theorem. Let B1(t,ω) be a Brownian motion under a probability measure P1: B1(t,ω) ∼ N(0, t) under P1. Define a new probability measure P2 related.

A change of numeraire argument is used to derive a general option parity, or equivalence, result relating American call and put prices, and to obtain new ex ...

Thus, by the Girsanov theorem, a change of drift in Wt (or equivalently in Xt) has no effect on quadratic variation.
