One of the keys to understanding the Federal Reserve is the Federal Reserve balance sheet (or balance statement). In accordance with Section 11 of the Federal Reserve Act, the board of governors of the Federal Reserve System publishes once each week the "Consolidated Statement of Condition of All Federal Reserve Banks" showing the condition of each Federal Reserve bank and a consolidated statement for all Federal Reserve banks. The board of governors requires that excess earnings of the Reserve Banks be transferred to the Treasury as interest on Federal Reserve notes.
