The Securities Exchange Act of 1934 (the Act) authorizes the Board to regulate securities credit extended by brokers, dealers, banks, and other lenders. The FR T-4, FR U-1, and FR G-3 are recordkeeping requirements for brokers and dealers, banks, and other lenders, respectively. The FR G-3 and FR U-1 document the purpose of loans secured by margin stock. For purposes of these forms, margin stock is defined as (1) stocks that are registered on a national securities exchange or any over-the-counter security designated for trading in the National Market System, (2) debt securities (bonds) that are convertible into such stocks, and (3) shares of most mutual funds. The FR T-4 documents the purpose of credit being extended when that credit is not to purchase, carry, or trade in securities and the credit is in excess of that otherwise permitted under Regulation T , Credit by Brokers and Dealers. Lenders that are not brokers, dealers, and banks making loans secured by margin stock must register and deregister with the Federal Reserve using the FR G-1 and FR G-2, respectively, and must file an annual report (FR G-4) while registered. The Federal Reserve uses the data collected by the FR G-1, FR G-2, and FR G-4 to identify lenders subject to the Board’s Regulation U (Credit by Banks or Persons other than Brokers or Dealers for the Purpose of Purchasing or Carrying Margin Stocks) to verify their compliance with the regulation, and to monitor margin credit.
