Look-Through Earnings
Berkshire's proportional share of the earnings of all investee companies — whether or not those earnings are distributed as dividends — reflecting the true economic ownership rather than reported GAAP income.
“We consider our 'look-through' earnings to be the sum of our reported operating earnings plus our share of the retained earnings of the companies in which we are invested.”
Concept Analysis
Definition & Origins
Look-through earnings is Buffett's concept for measuring Berkshire's true economic earnings: reported operating earnings plus Berkshire's proportionate share of the retained earnings of major portfolio companies — whether those earnings are distributed as dividends or not. Standard accounting requires Berkshire to report only dividends received from portfolio companies; look-through earnings capture the full proportionate share of economic value being created.
Core Ideas
The GAAP gap. If Coca-Cola earns $10 billion and pays Berkshire's 9% stake $450 million in dividends while retaining $550 million of Berkshire's proportionate earnings, GAAP shows Berkshire only the $450 million. But the retained $550 million — reinvested by Coca-Cola at 15%+ return on equity — creates real value for Berkshire's proportionate ownership interest. Look-through earnings count the full $1 billion.
Why retained earnings from investees matter. If Berkshire's portfolio companies retained and reinvested earnings at high rates, Berkshire benefits from that compounding even without receiving cash. The share price of those companies reflects the retained earnings over time, and Berkshire's share of that appreciation is real wealth creation. GAAP simply doesn't record it as income.
The calculation. Berkshire's look-through earnings = operating earnings of wholly owned businesses + dividends from securities portfolio + proportionate share of undistributed earnings from equity holdings. In practice, the third component has often been the largest, as major portfolio companies retained substantial fractions of their earnings for reinvestment.
Practical Application
The 1990 letter introduced look-through earnings explicitly, noting that Berkshire's GAAP earnings of roughly $300 million 'significantly understated' true economic earnings because it excluded Berkshire's proportionate share of retained earnings from Coca-Cola, Capital Cities/ABC, Gillette, and other major holdings. Buffett calculated the look-through figure at nearly $600 million — twice the GAAP earnings. This two-fold discrepancy highlighted the limitation of GAAP for evaluating holding companies with major equity stakes.
Common Misconceptions
Misconception 1: GAAP earnings accurately measure economic performance for holding companies. For insurance companies, banks, and industrial companies — where all income flows directly to the income statement — GAAP earnings are reasonable approximations. For holding companies with major equity stakes using the cost method of accounting, GAAP systematically understates the economic value being created.
Misconception 2: Look-through earnings are speculative. They are calculated from actual reported earnings of actual portfolio companies. The only 'look-through' element is including retained earnings that GAAP requires to be excluded from the investor's income statement — not projecting future earnings.
