In fiscal year 2017, we assessed the recoverability of the carrying value of our equity investment in AHG. We estimated the fair value of our investment using weighting of the results of the income and market approaches. An impairment loss was recognized for the difference between the carrying amount and the fair value of the investment as of 30 June 2017. There have been no events during fiscal years 2018 or 2019 requiring reassessment of our investment. For additional information, see Note 9, Summarized Financial Information of Equity Affiliates.
