(together. “TDK Defendants”), and NHK Spring Co., Ltd., NHK International NAT Peripheral (Dong Guan) Co., Ltd., NAT Peripheral (Hong Kong) Co., Ltd., and NHK Spring (Thailand) Co., Ltd. (together. “NHK Defendants”). This Notice only applies to Reseller Plaintiffs. The Reseller Plaintiffs are Now Micro. Inc., Integrated Technical Systems. Inc. d/b/a Network One. It Worx. Inc., Stephen Arvay, and Michael Medeiros, (together, the “Reseller Plaintiffs”).

The lawsuit alleges Defendants conspired to fix prices of suspension assemblies (“SAs”), a component contained in hard disk drives (“HDD”). SAs are a necessary component of HDDs and are found in products such as laptop and desktop computers, and computer servers. The Reseller Plaintiffs bought and resold HDDs that included SAs. Reseller Plaintiffs assert prices were higher as a result of the supracompetitive prices initially charged by Defendants to HDD manufacturers. who “passed on” those price increases to the Reseller Plaintiffs.

The Court “certified" a Reseller Class defined as: all persons or entities in the Indirect Purchaser States, except original equipment manufacturers, who, during the period from January 2003 through May 2016, purchased a Standalone Storage Device or Computer for resale, which included as a component part one or more SAs that were manufactured or sold by Defendants, any current or former subsidiary of Defendants, or any co-conspirator of Defendants.

The Court has not decided who is right or wrong. There is no money available now, and no guarantee there will be. However, if you are a member of the Reseller Class described above, your legal rights are affected, and you have a choice to make now.
