If the report is to be exploited urgently, the best way is not to delay taking it back from the CEO, following some guidelines though. If one of the team members has some special acquaintance with the CEO, delegate them to the boss. The delegate or representative of the team should just tell the boss the team wants to perfect the report and you believe the "amends" will make the document more effective. Let the boss know it won't take time to edit it, as s/he may get suspicious of the content and may want to look at it, creating a potential adverse effect.
