Dear Investor,

More new highs ...

We are pleased to report solid positive returns in November, continuing the
strong performance of the past three months, and which resulted in new highs in
all portfolios. Currencies were the most profitable sector as the US Dollar
continued to strengthen against the Euro and the Yen. The major theme continued
to be the rising US interest rate differentials and the persistent weakness of
the Yen. The fixed-income sector was profitable overall, but gains in short-term
interest rate instruments were partially offset by losses on the long end of the
curve as mid-month economic data eased the markets' fears of inflation. The same
data pushed equity indices higher across the globe which was a welcome result
for many investors, but it went against our positions. Energy prices continued
their slide in November with warmer than normal weather in many regions of the
country. This was good news for energy consumers, but caused losses for our
positions. Metals, although only a small part of our portfolios, saw significant
gains this month with Copper rising to new all-time highs and Gold closing over
$500 per ounce. As December begins we look forward to a strong finish to 2005.
We also want to take this opportunity to wish you a safe and healthy holiday
season and a prosperous New Year.

Sincerely,

Bruce Cleland
President & CEO
