Notes:

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

2.        Revenue items included in net asset value, with dividends payable
deducted on the ex-dividend date.

3.       Following the share issuance of 250,000 ordinary shares on 12
September 2017, the Company has 176,843,108 ordinary shares in issue.  

4.       With effect from 30 March 2017, the Company's Net Asset Value (NAV)
includes a provision for Capital Gains Tax potentially payable in Argentina. 
As at 13 September 2017 this provision was 1.62% of the NAV (0.86% on
unrealised gains and 0.76% on realised gains since 23 September 2013).  There
is considerable uncertainty as to whether the Capital Gains Tax will become
payable and there is currently no established mechanism for paying it. In the
event that no tax becomes payable the provision will be reversed.
