[1] | On May 12, 2020, the Company acquired an approximately 19.8% shareholding in Evolve I, Inc., a Washington corporation (“Evolve”) under the terms of a Share Subscription Agreement (“SSA”) for a consideration of approximately $249 thousand. However, based on an assessment of the business environment, the Company decided to dispose the holding and exit the acquisition. During the six months ended September 30, 2021, the Company received back partial shares of IGC common stock, which had been given pursuant to the SSA, in exchange for the return of its shareholding in Evolve. Accordingly, the Company cancelled the partial shares received by it and impaired its remaining investment of approximately $37 thousand.
