Teledyne Technologies CFO Riesenfeld Resigns

Engineering products maker Teledyne Technologies Inc. said its chief financial officer, Stefan Riesenfeld, has resigned to pursue a new position elsewhere. Effective immediately, Teledyne’s corporate controller, Dale Schnittjer, will serve as acting chief financial officer while the company searches for Riesenfeld’s replacement. Teledyne, based in Los Angeles, was spun off in December by Pittsburgh specialty metals producer Allegheny Technologies Inc., formerly known as Allegheny Teledyne. The announcement was made after U.S. markets closed. Teledyne, which makes sophisticated electronics and communication products and aerospace engines and components, fell 19 cents to close at $14.31 on the New York Stock Exchange.
