We note your response to our prior comment 1 and disagree with your analysis. See Securities Offering Reform Adopting Release (SEC Release No. 33-8591) (Aug. 3, 2005) (noting [c]ourts have held consistently that the date of a sale is the date of contractual commitment, not the date a confirmation is sent or received or payment is made ).
