Short Sales on ARCA During Listed Halts - Effective August 29, 2003

Until further notice, to ensure correct pricing of listed short sales on ArcaEx, any short sale order in a listed non-ETF stock that resides on the ArcaEx book will be cancelled if and when that stock is halted. If a short sale order in a listed non-ETF stock is sent during the period of the halt, it will be rejected.

Once the halt has ended and a Halt Auction has been conducted to reopen the stock, short sale orders will once again be accepted and processed according to regular ArcaEx trading rules.

If you have further questions about short sale processing, please call TradePortal.
