These amounts are interest-free, unsecured and repayable on demand. Upon disposal of the Disposal Group in June 2014, the Disposal Group owed the Company a sum of $17.8 million. Management of the Company evaluated the collectability of the remaining amount and determined that $1.8 million should be impaired and offset against the gain on disposal of subsidiaries from discontinued operations for the year ended September 30, 2014. During the years ended September 30, 2015, the Company determined that $1.8 million were recoverable. The recovery was treated as an adjustment to the gain on disposal of subsidiaries from discontinued operations for the year ended September 30, 2015.
