My mistake. The Colorado rule of evidence comports exactly with Federal rule 408.
Another info edit:
Although, in one annotated code:
--Situations in which someone acknowledges that a certain claim is valid or is valid to a certain extent, or statements to the effect: "I think your claim is worth ‘X’ number of dollars," are not offers within the meaning of CRE 408. Scott Co. of California v. MK-Ferguson, 832 P.2d 1000 (Colo. App. 1991).
--No error in admitting statements by plaintiff that a representative of defendants stated that he felt plaintiff's claims had merit in certain amount where court stated that situations in which someone acknowledges that a certain claim is valid or is valid to a certain extent, or statements to the effect: "I think your claim is worth ‘X’ number of dollars," are not offers within the meaning of this rule. Scott Co. of California v. MK-Ferguson, 832 P.2d 1000 (Colo. App. 1991).
