[1] During the second quarter of 2017, the Company determined that one of its subsidiaries in the US would not serve the core business or generate future cash flow. As no future cash flows will be generated from using the patents owned by this subsidiary, the Company estimated the fair value of those patents to be nil as of June 30, 2017. Fair value was determined using unobservable (Level 3) inputs. Impairment loss from patents of $63,621 was recognized in 2017 to write off the entire book value of the patents.
