Dear Investor,

Currency trading drives performance for the month...

Global central bank intervention, which includes the long-awaited FOMC rate cut
decision announced mid-month, restored investor confidence, and normalcy
returned to global financial markets. The Fund earned the majority of its gains
in the foreign exchange markets as higher-yielding currencies once again gained
favor.

Trading in the stock indices sector also posted positive results, as the markets
breathed a collective sigh of relief that the Federal Reserve was seriously
addressing the credit crisis and resulting economic impact.

Fixed Income trading finished slightly negative as yields on the long-end were
little changed and investor risk appetite increased only moderately into
month-end. Energy and base metals trading finished slightly negative as
fundamentals were ignored by the market's desire for commodities in this
weakening dollar environment which exacerbated price action to the upside.

Although Campbell portfolios maintained a lower risk posture throughout the
month of September, full re-engagement will resume in early October.

The third quarter 2007 proved unusually painful, but we look forward to the
potential opportunities the last quarter may provide. Please do not hesitate to
contact me if you have any questions.

Sincerely,

Terri Becks
President & CEO
