To my knowledge, there hasn't been any movement on the strategic petroleum reserve in the U.S. in response to the current price drop. What you have seen is substantial increases in non-strategic petroleum reserve storage in the U.S. and floating storage on tankers, etc., and people essentially betting on crude prices going up by storing crude oil, but that's not the strategic reserve. In terms of the strategic reserve, I don't really have anything to add.
