 2/Dollar value represents c.i.f. (cost, insurance, and freight) value at port of export.

 3/Values were derived by use of adjustment factors to exclude freight, insurance, and other charges incurred in

moving goods to port of export. Adjustment is made to convert values to an approximation of the producers' value 

of exported goods. Current adjustment factors are based on data for 1992 which are published in "Exports from

Manufacturing Establisments, AR92-1, Appendix B". The adjustment factor for this report is 0.7502.
