(A) A person whose failure to exercise ordinary care substantially contributes to an alteration of an instrument or to the making of a forged signature on an instrument is precluded from asserting the alteration or the forgery against a person who, in good faith, pays the instrument or takes it for value or for collection.
(B) Under division (A) of this section, if the person asserting the preclusion fails to exercise ordinary care in paying or taking the instrument and that failure substantially contributes to loss, the loss is allocated between the person precluded under division (A) of this section from asserting an alteration or forgery and the person asserting the preclusion according to the extent to which the failure of each to exercise ordinary care contributed to the loss.
(C) Under division (A) of this section, the burden of proving that a failure to exercise ordinary care contributed to an alteration of an instrument or to the making of a forged signature on an instrument is on the person asserting the preclusion. Under division (B) of this section, the burden of proving that a failure to exercise ordinary care in paying or taking an instrument substantially contributed to loss is on the person precluded.
