<Page> (LOGO) Futures and Hedge Funds WORLD MONITOR TRUST-- SERIES B MONTHLY REPORT/ DECEMBER 28, 2001 <Page> WORLD MONITOR TRUST--SERIES B - -------------------------------------------------------------------------------- Dear Interest Holder: Enclosed is the report for the period from December 1, 2001 to December 28, 2001 for the World Monitor Trust--Series B ('Series B'). The net asset value of an interest as of December 28, 2001 was $107.78, an increase of 1.57% from the November 30, 2001 value of $106.11. The calendar year-to-date return for Series B was a decrease of 11.56% as of December 28, 2001. Additionally, the return for the quarterly period from September 29, 2001 to December 28, 2001 was a decrease of 5.05%. Quarterly Market Overview The fourth quarter of 2001 was characterized by continued weakness in global economic markets. Heightened uncertainty in the wake of the terrorist attacks and concerns about deteriorating business conditions worldwide significantly slowed an already soft economy. After beginning the quarter down, global equity markets rallied in November only to weaken once again toward quarter-end. In the U.S., weakness in business spending, manufacturing and construction negatively affected labor markets causing layoffs and plant closings. Consumer confidence dropped sharply during the quarter resulting in decreased retail sales while consumer price inflation remained relatively subdued. Short- and long-term interest rates rallied sharply in November before falling again in December. The U.S. dollar started the quarter down against many major foreign currencies but strengthened slightly in November and December. Economic activity in Europe, the United Kingdom and other industrial economies remained weak throughout the quarter as well, stemming from a downturn in business and consumer confidence. In Japan, the sharp contraction in economic activity that began early in the year continued into the fourth quarter and the unemployment rate reached a record high. Most major emerging market economies also continued to experience economic slowdown which was related, in part, to weakness in industrialized economies. U.S. and European interest rate instruments began the quarter up as data indicated persistent weakness in the U.S. economy. In an effort to stimulate the economy, the U.S. Federal Reserve lowered interest rates by 50 basis points in October and by another 50 basis points in early November. The European Central Bank and the Bank of England each cut rates by 50 basis points as well. In mid-November, some positive economic news, the fall of Kabul, Afghanistan and an announcement by the U.S. Treasury regarding the cessation of sales of 30-year bonds, resulted in one of the greatest reversals the U.S. bond market has seen in decades. Interest rates climbed sharply in the U.S. and Europe causing bond prices to fall. In December, the Federal Reserve lowered rates by another 25 basis points and bond prices climbed slightly. After hitting lows in mid-September, U.S. and global equity markets rallied in November amid positive developments in the war in Afghanistan and sentiment that the U.S. economy may be emerging from recession. Equity markets reversed in December providing a negative return for the second consecutive year. In foreign exchange markets, the U.S. dollar started the quarter down against many major foreign currencies, but strengthened amid hopes of a recovery in the U.S. economy. The Japanese yen was weak throughout the quarter falling to a three-year low against the U.S. dollar and a two year-low against the euro as the Japanese economy continued to soften. Record unemployment, weakness in the equity markets and continued deflation contributed to the decline of the yen. The euro fell from its post September 11th highs against the U.S. dollar as investors anticipated a U.S. economic rebound. Additionally, apprehension that European banks would be negatively affected by the Argentinean debt default and concerns regarding the introduction of the physical euro currency helped depress the euro. The Swiss franc rose on news of the Argentinean debt default as investors sought a safe haven currency. Terror attacks, sluggish economies and mild winter weather limited growth in global demand for oil during the fourth quarter. Demand among oil-dependent wealthy countries contracted by more than 600,000 barrels a day versus the same period last year. A coordinated cut in oil output by OPEC and non-OPEC producers was agreed upon as OPEC tried to regain control of crude oil prices. Quarterly Performance of Series B The following is a summary of performance for the major sectors in which Series B traded: Metal (-): Metal prices fell throughout most of the quarter amid decreased demand due to weak global economic conditions. Long positions in aluminum, gold and copper resulted in losses. Energy (-): Long natural gas and crude oil positions incurred losses as demand decreased due to sluggish global economies and mild winter weather. Index (-): After hitting lows in mid-September, U.S. and global equity markets rallied sharply in November resulting in losses for short NASDAQ, euro DAX, Nikkei DOW and S&P 500 positions. Interest Rate (+): After starting the quarter down, interest rates climbed sharply in November resulting in one of the greatest U.S. bond market reversals in decades. Short positions in euro and Japanese bonds resulted in gains. Currency (+): The Japanese yen fell to a three-year low against the U.S. dollar as economic turmoil continued in Japan. Short Japanese yen positions resulted in gains. The estimated net asset value per interest as of January 28, 2002 was $107.11. Past performance is not necessarily indicative of future results.
