When a lender makes a loan to your business, and in the loan agreement takes a security interest (as collateral) in one or more of your assets, it may include a completed UCC-1 financing statement (UCC-1). A UCC-1 is a document that, when properly filed with the state (often the secretary of state’s office), provides notice to potential buyers of those assets, and notice to future creditors of your business that the earlier lender has a priority interest in those assets. Article 9 of the Uniform Commercial Code governs business or commercial transactions (loans, extensions of credit) that are secured by collateral, and provides for use of the UCC-1 filing. Vehicles, office equipment and fixtures, inventory, investment securities, accounts receivable, machinery, letters of credit, and other moveable, tangible items of value often serve as the collateral for a UCC-1.
