Chairman's Statement

This is my first statement to shareholders as Chairman, having been appointed
on 7 February 2003 to replace John Morrell who retired on that date. I would
like to take this opportunity to thank John for his sterling work as Chairman
of the Company over the last eight and a half years.

During the period Japanese markets have again performed poorly. Over the six
months to 31 January 2003 the net asset value of the Company fell by 28.5%.
This compares with declines in the Tokyo Stock Exchange First Section (TOPIX)
of 19.2%, the Second Section of 20.5% and the Nikkei OTC of 20.2%. Over this
same period, the Japanese Yen appreciated by 5.4% against Sterling. The
Company, having been hedged for much of the period, profited by around �197,000
from this operation. The portfolio is currently unhedged.

In April 2001, whilst reviewing benchmarks, the Board decided to set a maximum
market capitalisation at the time of purchase, US$1 billion, and to disregard
the Stock Market Index of quotation. The Board, in conjunction with the
Managers, now feel that such a rigid absolute number as US$1 billion could be
disadvantageous. It has been agreed that a revised guideline specifying the
bottom quartile by value of the Japanese market be set.

Corporate restructuring continues to gather pace and to a large extent
valuations are cheap in Japan, but this is largely justified by the poor
domestic situation and the risks that exist globally. Given this background, we
will continue to seek out opportunities amongst small growth-oriented
companies, operating in niche markets, that are not directly affected by the
broader economic environment.
