Informix Corp does not want to raise its stated goal of a 20% pre-tax gross margin, even though it has exceeded that goal in recent quarters, chairman and chief executive Phillip White told the conference. Our plan has always been aimed at 20%. We think we can be in the high teens or 20% going forward. In the fourth quarter last year Informix had a 25% pre-tax profit and in the recently completed first quarter it posted 23%, White said. We have to continue to invest in the field organisation and in research and development, White said. Informix exceeded its stated goal during times when it undershot its hiring figures or revenues were greater than had been expected, White told the conference.
