Becks ----------------------------------------- Theresa D. Becks, Chief Executive Officer Campbell & Company, Inc. Managing Owner Campbell Alternative Asset Trust Prepared without audit Dear Investor, Credit crisis continues to drive market turmoil at year-end... Losses for the Portfolio from currency trading continued into year-end as market participants sold high yielding currencies, particularly the British Pound. Fears that the UK housing market and general economic growth would slow caused the Pound to finish off 4% on the month. Smaller losses were experienced in fixed income trading and trading in equity indices as U.S. and European stock markets were extremely volatile in December, while Asian stocks continued to move lower. Small gains were recorded in base and precious metals as gold rallied 6% to all time highs amid strong buying in the face of a bounce in the U.S. Dollar. Campbell has responded to the performance difficulties of 2007 with intensified efforts in research, highlighting the need to diversify across investment horizons and to monitor and respond to sharp factor-risk contagion more nimbly. Our 36 years of experience shows that our investment in the research process continues to provide for evolutionary change, while our commitment to the discipline of systematic trading remains unchanged. We thank you for your patience and partnership in 2007, and look forward to the trading opportunities that 2008 should provide. Wishing you a happy, healthy and prosperous New Year. Please do not hesitate to contact me if you have any questions. Sincerely, Terri Becks President & CEO Campbell & Company, Inc. Managing Owner Campbell Alternative Asset Trust
