Short selling by certain entities and/or in connection with certain bona fide activities are excepted from the short sale prohibition:

* The short sale ban does not apply to registered market makers, block positioners, or other market makers obligated to quote in the over-the-counter market, to the extent they are selling short as part of bona fide market making in the relevant security. We understand that this exception allows ETF market makers, as a hedge, to short securities that are components of the ETF. Note, however, that it is not clear if a block positioner in ETFs is also excepted from the ban with respect to the component securities. The exact contours of this exception are likely to be further clarified by the SEC Staff.
