An ongoing business relationship shall be deemed to exist if the holder has engaged in a commercial, business, or professional transaction involving the sale, lease, license, or purchase of goods or services with the business entity or association or a predecessor-in-interest of the business entity or association within the dormancy period immediately following the date of the check, draft, credit balance, customer's overpayment, or unidentified remittance giving rise to the unclaimed property interest. As used in this subsection, "dormancy period" means the period during which the holder may hold the property interest before it is presumed to be abandoned. A "predecessor-in-interest" is a person or entity whose interest in a business entity or association was acquired by its successor-in-interest, whether by purchase of the business ownership interest, purchase of business assets, statutory merger or consolidation, and includes successive acquisitions by whatever means accomplished.Amended by 2014 Mo.
