Class action

A class action is brought against NHK Spring Co., Ltd., NHK International Corporation, NAT Peripheral (Honk Kong) Co., TDK Corporation, TDK U.S.A. Corporation, TDK Corporation of America, SAE Magnetics (HK) Ltd., Magnecomp Precision Technology Public Co. Ltd. and Hutchinson Technology Inc., in which it is alleged that they conspired to unduly increase the price of hard drive head suspension assemblies (“Hanger Kits”) in Canada. A Suspension Kit is one of the components of a hard drive, which are incorporated into a wide variety of electronic products, including computers, game consoles, personal digital recorders (or hard drive set-top boxes) and camcorders.

The class action seeks a judgment ordering the repayment of revenues generated by the artificially inflated portion of the prices of Suspension Packages and/or products equipped with one or more Suspension Packages.
