The Bureau of Economic Analysis calculates and publishes an earnings metric known as the National Income and Products Accounts which presents the value and composition of national output and the types of incomes generated in its production. One of the NIPA accounts is “corporate profits.” From the NIPA handbook: “Corporate profits represents the portion of the total income earned from current production that is accounted for by U.S. corporations.”
The BEA’s measurement of corporate profits is somewhat similar to using operating income from GAAP financial statements rather than net income. The BEA is attempting to isolate “profits from current production” from non-production noised introduced by GAAP accounting standards. “Profits from current production provide a comprehensive and consistent economic measure of the net income earned by all U.S. corporations. As such, it is unaffected by the changes in tax laws, and it is adjusted for non-reported and misreported income” (emphasis is mine).
