NYSE Arca Inc. announced today that a number of companies plan to voluntarily withdraw their securities from listing.

In each case, the securities will continue to be listed on the New York Stock Exchange. “The companies have decided to voluntarily withdraw their listing from NYSE Arca, Inc. to eliminate duplicative administrative requirements inherent with dual listings as a result of the NYSE Group’s recent merger with Archipelago Holdings, the parent company of NYSE Arca,” it said.

NYSE Arca will continue trading the securities of these companies on an unlisted trading privilege basis.

The list of companies includes: Caterpillar Inc., Federal National Mortgage Association (“Fannie Mae”), H. J. Heinz Company, Honeywell International Inc., H&R Block, Inc., IBM Corp., Lehman Brothers Holdings Inc., Marsh & McLennan Companies, Inc., The Stanley Works, and W.P. Carey & Co. LLC

The NYSE says that investors are advised to check the specific company’s and NYSE Arca’s Web site and the SEC EDGAR filing system for information regarding each company’s withdrawal status.
