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

Markets

The UK equity market rose in July, bouncing back by almost 7% after falling by 5%
in June, and nearly returning to the highs reached in May. Improving economic
data from around the world provided the boost to the market, along with some
positive comments through the current company reporting season. Financials, led
by banks and life insurers, were amongst the largest positive contributors to
market performance. Companies with more defensive earnings; oil producers,
tobacco, pharmaceuticals and food producers were the leading detractors as
macro data has improved.

Portfolio Performance

The portfolio returned +6.4% over the month, slightly behind the FTSE All-Share
Index return of +6.8%.

The main detractors to relative performance over the month included
defensive shares, reflecting a change in investor sentiment towards staples in
the last few weeks; holdings affected included Imperial Tobacco and Tate &
Lyle. The weak share price performance of Imperial Tobacco and British American
Tobacco demonstrated investor nervousness regarding their forthcoming results after 
US competitor, Philip Morris International's earnings were lower than had been
anticipated and the firm downgraded full year earnings expectations. Carphone
Warehouse shares fell on the announcement that Best Buy's shareholding would be
placed in the market, although the shares began to recover following good
results mid-month. Domino's Pizza reported high costs in its German business
though we believe that the growth potential and investment case remain intact.
Shares of motor insurer eSure Group were affected by declining overall market
premium rates.

Pharmaceutical group Shire's second quarter earnings exceeded market expectations
delivering strong sales revenues and the company raised earnings guidance for the
full year. Reed Elsevier, the global professional information company, reported
interim results with underlying revenue, operating profit and earnings growth.
The underweight position in BP helped relative returns after the oil
producer reported disappointing quarterly earnings with lower net profit on
weaker downstream revenues and a higher tax charge. Cash flow was weak,
highlighting the challenge that the company faces in meeting its dividend
payments from operating cash flow.

During the month we initiated new positions in Stagecoach, Phoenix Group and
Howden Joinery; and added to BHP Billiton and BSkyB holdings. We sold the Rexam
position, and trimmed holdings in Unilever, Ladbrokes and Admiral Group.

Outlook

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 in the UK, due mainly to the greater part
of the revenues of larger UK companies being derived overseas. Equity
valuations have been lifted by a downward reassessment of risk levels in equity
investment, given higher levels of inflation and lower bond yields. UK equity
valuations still look attractive compared to those of most other asset classes,
with the prospect of high quality earnings and dividend growth.

Given the relative valuations we remain confident about equities in anticipation of
a modest level of top-line growth, influenced by improving trends in earnings
prospects on a global basis. We continue to focus on income, stock selection
and building a high conviction portfolio to deliver both income and capital
growth.
