ACQUISITION TIME?: Zadig & Voltaire founder and owner Thierry Gillier declined to comment on reports in the French press Friday that he is in discussions with U.S.-based private equity firm TA Associates to sell a minority stake in the business. Gillier recently told WWD that despite receiving investment propositions on a regular basis, he was determined to keep the brand independent. Zadig & Voltaire expects revenues in the region of 300 million euros in 2012, or $396 million at current exchange, a spokeswoman for the brand confirmed. The brand operates 150 boutiques worldwide, half of which are in France. Between 30 and 40 openings are planned for this year in international markets, including a 2,000-square-foot store on Madison Avenue in New York City, scheduled to open at the end of April.
