16. | Related Party Transactions
At December 31, 2022, certain of our cash and short-term investments were held and managed by BlackRock, Inc. which owns 15.9% of our outstanding common stock as reported in its Form 13-G/A filing made with the Securities and Exchange Commission on January 20, 2023. We have an ownership interest in Fraes-und Technologiezentrum GmbH Frasdorf (“FTZ”), a company based in Germany that provides milling services to one of our wholly owned subsidiaries. This investment is accounted for under the equity method and is not material to our consolidated balance sheets. During 2022, 2021 and 2020, purchases of products from FTZ were not material. We also had an ownership interest in ETZ Elektrisches Testzentrum fuer Leiterplatten GmbH (“ETZ”) which provided our PCB Test business, atg-Luther & Maelzer GmbH, with certain component parts. Our ownership interest in ETZ was transferred on June 24, 2021 as part of the sale of the PCB Test business and ETZ is no longer a related party. During 2021 and 2020, purchases of products from ETZ, when it was a related party, were not material.
