Commenting on the markets, Adam Avigdori, representing the Investment Manager
noted:

Markets

March was the tenth consecutive month of positive performance for the UK equity
market. Equity markets globally made significant advances during the first
quarter as they overcame the disappointments of US sequestration, the UK
sovereign debt downgrade, the machinations of the Italian elections and the
bailout of Cypriot banks casting the spotlight back onto the Eurozone debt
crisis.

Portfolio Performance

During March the portfolio return of 0.1% underperformed the FTSE All-Share
Index, which returned 1.4%.

Amongst the top contributors to Fund returns was Playtech, the developer of
software platforms and content for the gaming industry, which performed well as
shares of online gaming companies surged on news of plans for a change in New
Jersey's Gambling Law; Playtech is the leading provider of the back-end
technology to many online gaming sites.

The largest detractor from portfolio returns was the holding in global
exhibitions and information company UBM, which reported 2012 results that
disappointed the market despite being slightly ahead of expectations as they
included the recently disposed of Delta businesses. However, the exhibitions
business has reported consistently good growth, driven primarily by exposure to
emerging markets. Shares of cruise operator Carnival fell after the company
announced that its ship the Carnival Triumph, which was crippled by an engine
fire in the Gulf of Mexico in February, will be out of service longer than had
been initially expected resulting in additional cruises being cancelled.

The portfolio's holding of Chilean copper miner Antofagasta detracted from
returns, with a mixture of stock specific and industry issues to blame;
Antofagasta's cost guidance for 2013 was disappointing as rising power prices
took their toll. The weakness of Antofagasta was more than offset in relative
terms by not holding other shares in the mining sector, such as BHP Billiton
and Anglo American, which also underperformed.

Transactions during the month included purchasing new positions in Diageo,
Ladbrokes, Legal & General and motor insurance specialist esure Group, and
adding to the holdings of British American Tobacco and Domino's Pizza. We
reduced holdings in Soco International, HSBC, Spectris, Prudential and Tullow
Oil, and sold the positions in Rio Tinto, BSkyB, Kingfisher and CSR.

Outlook

Markets seem to be no longer dominated by a simple "risk-on, risk-off" trading
mentality and it appears that risk-taking is now being rewarded on a more
fundamental basis. Economic data is improving globally but still far from
strong, and we have seen a continuation of supportive policy responses designed
to counteract the low GDP growth outlook. We expect domestic growth to remain
low and hence in this difficult economic environment we prefer to hold
positions in companies with global businesses and retain our preference for
companies with high quality franchises that can prosper through exposure to
growth markets.

The UK equity market provides investors with exposure to international markets
and we believe that the earnings of UK companies can still grow despite the
challenges of low nominal GDP growth. Our investment philosophy remains one of
picking shares that we believe can outperform the market, rather than taking
significant sector or style views. While individual positions may have exposure
to a particular theme, we avoid expressing significant macro views. Overall,
the portfolio remains well balanced and diversified.
