[1] Gains/(losses) arise due to (decreases)/increases in the forward-looking price of gold and the magnitude of any gain or loss is highly correlated to the magnitude of the change in the forward-looking price of gold. See Note 4 for significant unobservable assumption and a reconciliation of changes in the deferred consideration balances.

[2] Excludes participating securities as the Company reported a net loss for the period.
