As a comment around the assessment rate, I can imagine that when the holiday season comes, when Christmastime comes, the assessment rate will change because of the volume of packages coming into the country and being shipped. They may look at $20 or $25 today, but during holiday time they potentially can't look at $25 because of the volume. That would just slow down supply chains across the board.
