Shares of

Advo

( AD) were among the

NYSE's

losers Thursday, plummeting 27% after

Valassis Communications

(VCI)

sued the company to rescind its $1.3 billion merger agreement.

Valassis, which in July agreed to acquire Advo for $37 a share, said that Advo materially misrepresented its financial health and failed to reveal internal control deficiencies. "We believe that taking this action is in the best interest of our shareholders," Valassis said in a press release late Wednesday.

Advo, meanwhile, said it believes the lawsuit is baseless, and it will take action to enforce the merger agreement. The company said that Valassis' attempt to pull the plug on the deal "is merely a smoke screen to hide the fact that Valassis is suffering from an extreme case of buyer's remorse." Shares of Advo were recently trading down $9.85 to $26.95, while shares of Valassis were trading up 31 cents to $21.32.
