In 1986 Berkshire Hathaway Shareholder Letter, Warren Buffett defined owner earnings as follows:

"These represent (a) reported earnings plus (b) depreciation, depletion, amortization, and certain other non-cash charges...less (c) the average annual amount of capitalized expenditures for plant and equipment, etc. that the business requires to fully maintain its long-term competitive position and its unit volume (If the business requires additional working capital to maintain its competitive position and unit volume, the increment also should be included in (c))...Our owner-earnings equation does not yield the deceptively precise figures provided by GAAP, since (c) must be a guess - and one sometimes very difficult to make. Despite this problem, we consider the owner earnings figure, not the GAAP figure, to be the relevant item for valuation purposes - both for investors in buying stocks and for managers in buying entire businesses...All of this points up the absurdity of the 'cash flow' numbers that are often set forth in Wall Street reports. These numbers routinely include (a) plus (b) - but do not subtract (c)."
