For the AMAT, we expect to reach sales of 250,000-this is roughly the same figure as last year and it may be a little pessimistic, as we are going to do a large-scale promotion campaign during the year-so perhaps we will achieve something like 300,000. Still I prefer to keep the forecast at 250,000. Now, we come to the BMAT. Here sales should reach 450,000. This could be a little optimistic as we are not going to push this product in 1998. In any case, the total will probably balance out with the more conservative forecast for the AMAT. The CMAT, our most recent product, will continue to do well. Sales may go as high as 600,000. However, I have set the target slightly lower at 550,000. OK, let's turn to our medium-term plans.At the beginning of 1998 we are going to launch our new product-the DMAT-and we are sure sales will take off very quickly. We estimate first year sales at 200,000. The DMAT should initially complement the AMAT and eventually replace it in the nineties. Finally, R & D are working hard on a medium range produce-they hope to have it ready by 1999 so we could launch it in 2000.
