Avon Products used Brunswick Group to deal with fallout connected with the May 14 filing on the Securities and Exchange online database of a bogus $18.75 per-share takeover bid, which triggered a 20 percent spike in its shares.

avonAn unknown outfit called PTG Capital Partners was purportedly behind the tender offer.

Avon issued a statement to say, "It has not received any offer or other communication from such an entity and has not been able to confirm that such an entity exists."

The beauty products marketer's lackluster performance has increased pressure to find a buyer.

In April, CEO Sherilyn McCoy announced a plan to explore strategic options, such as a sale or split-up.

Avon rejected a $10.7B deal with Coty in 2012.

Avon shares closed up six percent on May 14 to $7.07 each.

Brunswick's Radina Russell assisted Avon group VP-IR Amy Low Chasen in handling the response to the phony filing.
