All figures are listed in US$ but in some cases have been converted from local currencies at average exchange rates for 2004. Wherever possible, sales/turnover volumes relate to 2003/4. Those sales/turnover volumes have been compiled from a variety of sources including survey responses and financial institution data records, but D&Ri cannot be held responsible for any errors or omissions. In some cases, however, detailed information has been impossible to obtain and consequently * after the sales volume indicates an estimated figure based on historical data and other sources.
