My Level Two Screen is now showing a UPC code --
I thought the Nasdaq definition might interest somebody:
1999 Uniform Practice Code Advisories (UPC)
Uniform Practice Code Advisories are notices which are issued pertaining to unusual circumstances such as extremely large dividends, when-issued settlement dates, ex-interest dates for bonds, worthless securities, cancelled IPOs, etc. Their intent is to announce rulings, interpretations, exemptions, and advisories on these subjects in order to facilitate the transaction of a member's day-to-day business and to eliminate business disputes and misunderstandings which may arise from uncertainty and lack of uniformity in such matters.
The subjects addressed in the Uniform Practice Code Advisories are subject to the provisions of NASD Uniform Practice Code (Rule 11000 Series) which is administered by the Market Operations Department of The Nasdaq Stock Market, Inc. They appear on the NASD Web site to facilitate a member's compliance with NASD regulations.
