Subject: naked short and regular shorting restrictions

September 15, 2008

Sirs:

I would urge:

1- a complete ban on the practice commonly known as "naked shorting" for all securities under the jurisdiction of the SEC. If a party does not own a security or can borrow it, they should not be able to sell the security.

2- an alteration of the notification rules to an owner of a security regarding the borrowing of the security for the use in the practice commonly known as "shorting". Account holders should be notified every instance where their securities are proposed to be borrowed, and should be required to give active approval on a case by case instance.
