Bob Shearer and Kathleen Anderson, representing the Investment Manager, noted:

Performance

For the one month period ended 31 July 2014, the Company's NAV decreased by
0.8% while the share price declined by 3.9% (all in sterling). The Company's
benchmark, the Russell 1000 Value Index, fell by 0.4% for the period.

On a relative basis, the largest contributor to relative performance was strong
stock selection in the industrials sector, followed by a combination of stock
selection and a small underweight position in the utilities sector. Individual
security selection within information technology, as well as the combination of
strong selection and a marginal overweight within telecommunications, also
added to relative performance during the month.

The largest detractor from relative performance for the month was stock
selection within consumer staples, particularly owning Coca-Cola, Diageo and
Kraft, all out-of-index positions that posted negative returns for the month.
Selection within both financials and consumer discretionary were also weaker
during the quarter; and the combination of a general underweight in information
technology and an overweight in industrials also detracted from performance.

Transactions/Options

Transactions: In July, we sold Veritiv, a small-cap, non-dividend paying spin
out from our position in International Paper. There were no other complete
purchases or sales during the period.

As of 31 July 2014, the Company's options exposure was 17.85% and the delta of
the options was 96.57%.

Positioning

We are currently overweight to the industrials, consumer discretionary,
materials, consumer staples and telecom sectors. We are underweight to the
financials, health care, information technology, utilities and energy sectors.

Conversations with our management teams and economic data points (ISM,
employment, housing, etc) continue to support our view that the US economy is
slowly gaining strength. This economic improvement, the end of QE3, and
ultimately Fed action will likely cause interest rates (and volatility) to
drift higher. As the bounty of abundant liquidity is withdrawn, we expect
profitable companies with strong balance sheets, dominant competitive positions
and consistent earnings and dividend growth potential to outperform.
