Commenting on the markets, Will Landers, representing the investment
Manager noted;

Performance

For the month of August 2011, the Company posted a 5.3% decline in its NAV
while the shares fell by 1.9% (all in sterling terms). This trailed the

-4.6% return posted by the Company's benchmark, the MSCI EM Latin America
Index.

The Company benefited primarily from stock selection in Brazil, Chile and
Mexico and an overweight position in Panama via Copa Airlines. The largest
individual positive contributors for the month included an underweight position
in Petrobras, overweight positions in Ambev and Copa Airlines and not owning
Cemex. Offsetting some of the underperformance relative to the benchmark for
the month was an off-benchmark position in Colombia via Pacific Rubiales and an
underweight to Colombia. Individual negative contributions to performance for
the month came from iron ore giant Vale and overweights to Itau, Pacific
Rubiales and Profarma.

Transactions/Gearing

During the month in Brazil, we added to financials on weakness, reintroduced
credit card acquirers, added to utilities while we reduced and diversified our
exposure to oil & gas by reducing Petrobras, OGX and Pacific Rubiales and
adding HRT. In addition, we increased exposure to Peru. Other sources of
funding for these changes during the month included reducing exposure to
Brazilian petrochemicals and consumers, Mexican banks and construction and
Panamanian airlines.

Positioning

Brazil is at the forefront in terms of starting to cut rates to ensure that its
economy does not suffer as big a slowdown as that which is expected from the US
and Europe. Unfortunately, the correlation among markets remains high, so as
long as the European situation is in question, it may lead to continued
volatility in Latin America. However, the fundamentals are good, the new
government in Brazil is working well, and valuations are very cheap - all of
which makes for an attractive entry point into the region. Brazil continues to
be an overweight while Mexico, Chile, Colombia and Peru remain underweights.
