NEW YORK (AP) — Tiffany & Co. has named industry veteran Roger Farah as chairman, effective Oct. 2. Farah, 64, joined the upscale jeweler's board in March and had served in leadership roles at Ralph Lauren Corp., Venator Group Inc., among others. The move is part of a management overhaul pushed by activist investor Janna Partners to revitalize sales at Tiffany, which has struggled with intensifying competition from online players like Amazon and Blue Nile.
