Come September 27th, you won’t be able to find a price quote for Publicis Groupe on the New York Stock Exchange. The Paris-based ad agency giant has filed to voluntarily delist its American Depositary Receipts (ADR), which is how its stock is traded in the US. The ADRs will still trade over-the-counter, but Publicis will no longer make filings with the SEC. The company says it is strictly a financial decision. Trading of the US ADRs amounts to only about 1% of the total volume of trading in Publicis stock and the company says it will save on no longer having to report its financial results under both the International Financial Reporting Standards and the GAAP standards used in the US.
