We historically conducted business with a related party company, Lite-On Semiconductor Corporation; (“LSC”), and its subsidiaries and affiliates.

C.H. Chen, our former President and Chief Executive Officer and currently the Vice Chairman of the Board of Directors, was also Vice Chairman of LSC and a board member of LTC. Dr. Keh-Shew Lu, our current

Chairman of the Board of Directors, President and Chief Executive Officer, is a board member of LTC, and a board member of Nuvoton. We consider our relationships Nuvoton to be mutually beneficial and we plan to continue our strategic alliance with Nuvoton. We purchase wafers from Nuvoton for use in our production process. We also conduct business with Nuvoton Technology Corporation and its subsidiaries and affiliates (collectively, “Nuvoton”).

We also conduct business with Keylink International (B.V.I.) Inc. and its subsidiaries and affiliates (“Keylink”). Keylink is our 5% joint venture partner in our Shanghai assembly and test facilities. We sell products to, and purchase inventory from, companies owned by Keylink. We sold products to companies owned by Keylink, totaling approximately 2% for the 12 months ended December 31, 2020 and 1% of net sales for each of the twelve month periods ended December 31, 2019 and 2018. In addition, our subsidiaries in China lease their manufacturing facilities in Shanghai from, and subcontract a portion of our manufacturing process (metal plating and environmental services) to, Keylink. We also pay a consulting fee to Keylink. The aggregate amounts paid to Keylink for the years ended December 31, 2020, 2019 and 2018 were approximately $14.6 million, $15.3 million and $16.6 million, respectively.
