The gold certificate account reflects the receipts issued to the Reserve Banks by the Treasury against its gold holdings. In return, the Reserve Banks issue an equal value of credits to the general account of the Treasury, computed at the statutory price of $42.22 per troy ounce. Because nearly all of the gold held by the Treasury has been monetized in this fashion, the Federal Reserve Banks' gold certificate account of $11 billion represents the nation's entire official gold stock.

The industrial production (IP) index measures the real output of all relevant establishments located in the United States, regardless of their ownership, but not those located in U.S. territories.

The Industrial Production (IP) proportions (typically shown in the first column of the relevant tables in the G.17 release) are estimates of the industries' relative contributions to overall growth in the following year. For example, the relative importance weight of the motor vehicles and parts industry is about 6 percent. If output in this industry increased 10 percent in a month, then this gain would boost growth in total IP by 6/10 percentage point (0.06 x 10% = 0.6%).
