Thomas Tille owned M. A. T. T. Equipment Co. To operate the business, Tille borrowed funds from Union Bank. For each loan, Union filed a financing statement that included Tille’s signature and address, the bank’s address, and a description of the collateral. The first loan covered all of Tille’s equipment, including “any after- acquired property.” The second loan covered a truck crane “whether owned now or acquired later.” The third loan covered a “Bobcat mini- excavator.” Did these financing statements perfect Union’s security interests? Explain.
