The Supplement includes the entire Uniform Commercial Code as of May 2020, excluding Article 6, and also includes a selection of other federal statutes and regulations, uniform state laws, and Restatement provisions, aiming to include those items most commonly used in commercial law courses. This leads, among other things, to the inclusion of the Truth in Lending Act, Electronic Funds Transfer Act, the Federal Tax Lien Act, the Uniform Electronic Transactions Act, excerpts from the CISG, and from the ICC’s uniform rules for letters of credit. The Bankruptcy Code, as of June 1, 2020, is reproduced in full. Unlike the UCC, there are no official comments for the Bankruptcy Code, and the legislative history is spotty at best. As a result, only the Code is offered here. In addition, selections from Title 18 and Title 28 of the United States Code that are relevant to bankruptcy law are included. New to the 2020 Edition: Small Business Reorganization Act (SBRA), new subchapter V of Chapter 11 of the Bankruptcy Code, effective February 1, 2020, a major revision of the Bankruptcy Code. Section 104(b) of the Bankruptcy Code provides for readjustment of certain dollar figures at three-year intervals beginning in 1998. For this supplement, the current dollar amounts, amended as of April 1, 2019, are listed, along with notes to remind the reader that they will change again in March 2022 (taking effect on April 1, 2022). Revisions to Regulation E related to prepaid cards. Updates to sections 9-406 and 408 of the UCC and comments.
