4.         Investments have been valued on a bid price basis.

5.        Within the Trust's unquoted investments, following recent gold price
weakness and in line with the fall in the price of Banro's senior secured
notes, the Board in conjunction with a recommendation from the BlackRock
Pricing Committee, has increased the discount applied against the valuation of
the gold-linked preference shares from 15% to 30%. This has resulted in a 47bps
reduction to the NAV of the Trust from 14th August 2015.
