Owner Earnings

Definition

Owner earnings are reported earnings plus non-cash charges like depreciation and amortization, minus the average capital expenditure a business needs each year just to maintain its unit volume and competitive position. Buffett states the point directly: "we consider the owner earnings figure, not the GAAP figure, to be the relevant item for valuation purposes." Unlike GAAP net income or naive "cash flow" (earnings plus depreciation with nothing subtracted), owner earnings forces in an estimate — necessarily imprecise — of what maintenance capex actually costs.

In the Book

The concept is developed through the 1986 acquisition of Scott Fetzer, restructured into an "old" company and a "new" company with identical operations but different accounting bases after the purchase. GAAP produced two different reported-earnings figures for the same underlying business — one showing $40.2 million, the other $28.6 million — purely from how the purchase price was allocated on the balance sheet. Buffett uses this to show GAAP earnings can diverge sharply from economic reality, and works through the owner-earnings formula to show that, properly calculated, both entities have identical earning power. He extends the critique to Wall Street "cash flow" figures generally, arguing they mislead by adding back depreciation without subtracting the capital spending a business must make to avoid decaying — citing the oil industry as an example of companies that would have shrunk in real terms had they only reinvested at the depreciation-charge level.

Why It Matters

Any reported number that a preparer controls — earnings, cash flow, adjusted metrics of any kind — can be shaped to look better than the underlying reality without anyone lying. Owner earnings is a discipline for stripping that distortion out: ask what the enterprise could actually pay out forever without shrinking, not what the accounting convention happens to report this year. The same move applies wherever a reported metric and an economic reality can be pulled apart — a project's "on-budget" status that ignores looming rework, a team's velocity that ignores accumulating technical debt.
