LONDON (Dow Jones)--Tandem Group PLC (TND.LN), a manufacturer and distributor of sports and leisure equipment, said Monday revenue for the 20 weeks to June 18 was 8% above the comparative period last year. MAIN FACTS: -Trading conditions continue to be difficult due to cost pressures in respect of U.S. dollar volatility and increases in freight and raw material prices. -It has not been possible to pass all of these additional costs on to customer mid-season and this has had an adverse impact on profit margins. -The Group continues to strengthen the balance sheet, stockholdings have been reduced and this has resulted in an improved cash position. -Shares at 1300 GMT up 2.5 pence, or 2.3%, at 109 pence. -By Tommy Stubbington, Dow Jones Newswires; 44-20-7842-9268; tommy.stubbington@dowjones.com (END) Dow Jones Newswires June 21, 2010 09:04 ET (13:04 GMT)
