Dear Investor,

A strong start to a New Year ...

Fixed Income was a primary driver of performance in January as global economic
momentum continued to accelerate. Growth in payrolls, firming retail sales,
bottoming housing data and upbeat consumer confidence drove US bond prices
lower, while European prices also declined on six year highs in consumer
confidence and five year lows in German unemployment. Additional gains from the
equity index sector resulted as prices continued their steady upward movement on
strong M&A activity.

Small currency gains were driven by UK-related crosses as the Bank of England
unexpectedly raised rates to combat rising inflation, while Energy losses were
driven by price declines on inventory build-ups due to warmer than average
temperatures.

On a personal note, following the completion of treatment, a recent scan
indicated that I am free and clear of cancer. Still some healing to do, but
otherwise a truly good start to the New Year.

Sincerely,

Bruce Cleland
