"We feel that the undistributed earnings of companies we hold in large amounts are fully as important to us as those we report." (1978) "References to EBITDA make us shudder — does management think the tooth fairy pays for capital expenditures?" (2000)
I — Methodology skeleton
Two core concepts merged into one skill:
Look-through earnings: true economic earnings = reported profit + share of undistributed profits of investee companies - assumed taxes
- Accounting only shows dividends received, but undistributed profits are also yours (if you have control or hold long term)
Owner earnings: net profit + depreciation and amortization - maintenance capital expenditures ≠ EBITDA
- Depreciation is not a "non-cash expense" — it is the recovery of prepaid capital
- EBITDA ignores the real capital expenditures needed to maintain competitive position
A1 — Application in the book
Case: Apple's look-through earnings
- Question: How much does Berkshire get from its Apple investment?
- Use: In 2021 Berkshire's share of Apple's earnings = $5.6 billion, but dividends received were only $785 million
- Result: Accounting profit severely underestimates true economic progress (a 7x difference)
A2 — Trigger scenarios
- Analyze a company with high profits but also high capital expenditures
- Assess the true profitability of a controlling/shareholding company
- Someone is using EBITDA for valuation — you need to point out the problem
- Understand why net profit and cash flow differ greatly
Language signals
- "This company has very high EBITDA"
- "Depreciation is not a cash cost"
- "Why do profit and cash flow differ so much?"
- "Do undistributed profits count as mine?"
Distinction from adjacent skills
- With
economic-moatdifference: moat analysis examines corporate competitiveness, look-through earnings examines the company's true ability to make money
E — Executable steps
-
Calculate owner earnings = net profit + depreciation and amortization - maintenance capital expenditures
- Completion standard: distinguish "maintenance" vs "expansion" capital expenditures
-
Check the EBITDA trap
- Completion standard: if EBITDA >> owner earnings, mark "earnings quality questionable"
- Stop rule: if the gap between EBITDA and free cash flow is >50% → issue a warning
-
Calculate look-through earnings(applicable when there are shareholding companies)
- Completion standard: reported profit + proportional share of undistributed profits - assumed taxes
B — Boundaries
- Estimating "maintenance" vs "expansion" capital expenditures requires judgment — different people may reach different conclusions
- Look-through earnings are of little significance to short-term investors (undistributed profits may never be realized)
- Author blind spot: Buffett has enough control to ensure undistributed profits are eventually realized — retail investors do not
