Commenting on the markets, Will Landers, representing the investment

Manager noted;

Performance

For the month of March 2011, the Company posted a 3.5% gain in its NAV while
the shares appreciated by 2.9% (all in sterling terms). This trailed the 5.1%
return posted by the Company's benchmark, the MSCI EM Latin America Index.

The underperformance versus the benchmark during the month stemmed primarily
from stock selection in Chile and Mexico as well as an off-benchmark position
in Colombia via Pacific Rubiales. Other individual names that were the largest
individual negative contributors for the month included Totvs, Copa and America
Movil. The underperformance was partially offset by stock selection in Brazil.
Positive contributions to performance for the month came from Itau,
Hypermarcus, Localiza and Queiroz Galvao.

Transactions/Gearing

During the month, we added to consumer and petrochemical positions in Brazil,
Chilean banks and Mexican consumer names. These moves were funded by reducing
exposure to Brazilian industrials, utilities and wireless telcos, Chilean
retailers and off-benchmark Argentina.

Positioning

At the end of the quarter, the portfolio is positioned to benefit from a
recovery in risk appetite. Latin America's fundamentals, from both a macro and
micro perspective, rank among the most attractive in the world in our opinion
and we would expect to see the region rank among the best in the world in
periods of market recovery. Brazil remains our largest overweight with a
continued focus on domestic sectors representing most of the overweight. We
expect the Brazilian Central Bank to finish its current tightening cycle at its
next meeting in April which should help inflation revert to its target level in
2012. Valuations in Mexico are, for the most part, pricing in the ongoing
recovery in the United States, though we are concerned with some of the soft
macro numbers out of the US and their potential impact given the close
correlation between Mexico and the US. Other markets in the region have some
representation in the portfolio but suffer from a combination of higher
valuations and/or low liquidity.
