Berkshire Hathaway 1990 Shareholder Letter: A Management Philosophy on Look-Through Earnings and Intrinsic Value

In the 1990 shareholder letter, Warren Buffett elaborated on the core investment and management philosophies of Berkshire Hathaway (United States). This letter is not merely a financial disclosure but an educational material on how to see through accounting appearances to grasp the economic substance of businesses.

First, Buffett introduced the concept of "Look-Through Earnings" to address the limitations of traditional accounting standards. He pointed out that the retained earnings of many investee companies held by Berkshire (such as Coca-Cola and The Washington Post) far exceeded the dividends they paid, yet GAAP only recorded the received dividend portion. This accounting method obscured the true growth in economic value. Buffett emphasized: "We don't care if the auditor hears the tree fall in the forest; we care about who owns the tree and what happens to it next." By calculating "look-through earnings," which include the share of retained earnings from investee companies, investors can more accurately assess a company's true profitability rather than relying solely on reported figures.

Second, the letter clarified that management's goal is to align shareholder returns with the growth of the company's intrinsic value. Buffett wrote: "Ideally, each Berkshire shareholder's results should closely mirror those of the company during their holding period." He acknowledged that intrinsic value is an estimate, and even he and Charlie Munger might differ by 10% in their assessments, but insisted that pursuing an average annual growth in intrinsic value (targeting 15%) was more important than focusing solely on book value or stock price fluctuations. This view reminds investors that while stock prices may deviate from value in the short term, in the long run, individual returns fully reflect company performance only when the premium/discount ratios at purchase and sale are consistent.

Finally, Buffett detailed Berkshire's unique decentralized operating model and its impact on capital allocation. He explicitly stated: "My areas of responsibility are capital allocation and the selection and compensation of senior managers." Other operational decisions were left to subsidiary managers. This model relies on identifying and retaining excellent managers, who send generated cash back to headquarters for intelligent deployment by Buffett. He illustrated in the letter that even if some business managers never visited the Omaha headquarters or met each other, they still operated efficiently. This structure ensured that Berkshire could focus on finding businesses with durable competitive advantages and achieve optimal capital allocation without interfering in daily operations.
