We historically conducted business with a related party company, Lite-On Semiconductor Corporation (“LSC”), and its subsidiaries and affiliates. LSC was also our largest stockholder, owning approximately 15% of our outstanding Common Stock., prior to the close of the acquisition of LSC by Diodes. On November 30, 2020, we acquired LSC and LSC is no longer a stockholder or related party, but instead it is a wholly owned subsidiary of ours. Raymond Soong, the former Chairman of the Board of Diodes, was the Chairman of LSC and was the Chairman of Lite-On Technology Corporation (“LTC”), which was a significant shareholder of LSC. C.H. Chen, our former President and Chief Executive Officer and currently the Vice Chairman of the Board of Diodes, was also the Vice Chairman of LSC and a board member of LTC. Dr. Keh-Shew Lu, our current Chairman of the Board, President and Chief Executive Officer, is a board member of LTC and a board member of Nuvoton Technology Corporation (“Nuvoton”). We purchase wafers from Nuvoton for use in our production process. We also conduct business with Nuvoton and its subsidiaries and affiliates. We consider our relationship with Nuvoton to be mutually beneficial and we plan to continue our strategic alliance with Nuvoton.

We 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 1.0% and 1.7% of our net sales for the three months ended June 30, 2021 and 2020, respectively. We sold products to companies owned by Keylink, totaling approximately 1.2% and 1.6% of our net sales for the six months ended June 30, 2021 and 2020, respectively. 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 three months ended June 30, 2021 and, 2020 were approximately $4.3 million and $3.8 million, respectively. The aggregate amounts paid to Keylink for the six months ended June 30, 2021 and, 2020 were approximately $8.7 million and $6.9 million, respectively. In addition, Chengdu Ya Guang Electronic Company Limited (“Ya Guang”) is our 2% joint venture partner in one of our Chengdu assembly and test facilities and our 5% partner in our other Chengdu assembly and test facilities; however, we have no material transactions with Ya Guang, other than these joint ventures. We also purchase materials from Jiyuan Crystal Photoelectric Frequency Technology Ltd.
