American Medical International was informed that Ft. Worth-based Investment L. P., one of four investment groups with a major stake in AMI, has withdrawn a proposal that would have given each group a seat on AMI’s board of directors. The four groups collectively own nearly a third of the company. The proposal, submitted to Beverly Hills-based AMI last month, also called for the formation of a restructuring committee that would consider ways to reorganize AMI. Investment L. P. said it was withdrawing its proposal because of the “negative response” that it received from AMI’s management.
