“商业判断规则”起源于170年前。但什么是商业判断规则却很难界定。一般认为,董事、高级管理人员善意地进行商业决策即可满足注意义务的要求,如果:(1)他与所进行的商业决策事项不存在利害关系(He is not interested in the subject of his business judgment);(2)他对所进行的商业决策是了解的,并合理地相信在该种情况下是适当的(He is informed with respect to the subject of his business judgment to the extent he reasonably believes to be appropriate under the circumstance);(3)他理性地相信其商业决策符合公司的最佳利益(He rationally believes that his business judgment is in the best interest of the corporation)引自第404页
