The Oregon UCC-1Ad Financing Statement Addendum is a form used to supplement a UCC-1 Financing Statement in the state of Oregon, and is used to show any changes to the original financing statement. It is typically used to add additional sections to the original document, such as additional collateral, an amendment to the original terms, or the addition of a secured party. The Oregon UCC-1Ad Financing Statement Addendum must be completed and signed by the secured party, and must be filed with the Secretary of State. There are two types of Oregon UCC-1Ad Financing Statement Addendums: the Standard Addendum and the Custom Addendum. The Standard Addendum is used to add additional sections to the original financing statement, while the Custom Addendum is used to amend the original terms of the financing statement.
