1. Equals the third-quarter 1982 current-dollar level for the component times the change in the chain-type index for the component.

2. Equals the dollar change of the component divided by the dollar change of GDP (multiplied by 100).

3. Because of the method used in calculating the change in business inventories, chain-type indexes cannot be constructed for it. Thus, the residual can be calculated only at the major component level.
