We set the monetary policy with the goal of getting inflation back to target. As we said in the opening remarks, the fact that inflation has persistently been below target means that we have to take more weight on the possible downward biases on inflation, because that would mean that any negative inflation shock would bring us even further away from target as opposed to getting closer. In that context we've decided that we should no longer have an explicit bias toward higher interest rates. In that context it's true that markets have digested that and have sold the Canadian dollar a little, but it's not a very significant change.
