Sorry, I was talking about the bilateral safeguard chapter, which involves the fact that while tariffs on sensitive goods aren't usually reduced immediately, they're phased out over a certain period. Usually what we would negotiate is a bilateral safeguard mechanism that allows you to return to those previous tariff levels, should there be injury caused from imports of those products into the market that resulted from the tariff decrease. It allows you to maintain the higher level for a certain period of time to the end of the phase-out period--for a year or two.
