Effective June 29, 2018, we sold our remaining 15% ownership interest in Kingstone Hong Kong to the majority owner for approximately $5.7 million. We recognized a pre-tax gain on the sale of approximately $2.9 million. The 2018 gain is reported as a gain on sale of other assets in our Consolidated Statements of Operations. Kingstone Hong Kong and its owners are no longer related parties of Amtech. As of June 30, 2017, SoLayTec had borrowed approximately $2.4 million, including accrued interest, from its minority shareholders. These loans were forgiven as part of the Exit Agreement entered into in July 2017. See Note 16 for additional information. SoLayTec and its owners are no longer related parties of Amtech.
