After the close of business on June 30, 2015, the Company contributed substantially all of its assets to FVI in return for a controlling general partner ownership interest in FVI.

Each subsidiary was formed for the purpose of holding one or more investments made by the Company, and was treated as a controlled foreign corporation under the Internal Revenue Code not separately subject to U.S. federal income tax. FVI was treated as the sole U.S. shareholder of each subsidiary. The Board of Directors of the Company approved the liquidation of those three Cayman subsidiaries on November 2, 2018. That liquidation was completed on December 27, 2018.
