As current 38/43 mL chain saws do not comply with exhaust gas regulations, we are selling these products on
credit in North America and according to small-quantity production regulatory limits in Europe. Therefore, we
cannot expand the sales of such products. And in line with the trend toward targeting general users instead of
semiprofessionals for chain saws of the 40 mL displacement class, other companies have been releasing new
products with lower prices. To compete with this situation, we are releasing these two new models.
