Buffett's 2010 Shareholder Letter: Capital Allocation Logic Anchored in Book Value

In the 2010 letter to shareholders, Warren Buffett detailed Berkshire Hathaway's performance measurement standards and major capital decisions. Facing market volatility, he did not pursue short-term stock price performance but emphasized establishing a mechanism for long-term intrinsic value growth. This letter not only recorded the financial results of that year but also revealed the management philosophy behind them.

First, Buffett clarified the benchmark for performance evaluation. He stated: "To eliminate subjectivity, we therefore use an understated proxy for intrinsic-value – book value – when measuring our performance." This approach aims to eliminate biases caused by subjective judgment. Although the market value of some businesses is far higher than their book value, using conservative book value as a proxy indicator can more objectively reflect whether management has truly created returns for shareholders that exceed the index.

Second, the letter focused on analyzing the logic behind the acquisition of Burlington Northern Santa Fe (BNSF) railroad company. Buffett believed that railroads have significant cost and environmental advantages over trucking: "That’s three times more fuel-efficient than trucking is, which means our railroad owns an important advantage in operating costs." This structural advantage made BNSF a core asset for enhancing Berkshire's "normal" earnings power, with pre-tax income expected to increase by nearly 40%.

Additionally, Buffett emphasized managing uncertainty from a long-term perspective. He mentioned: "Money will always flow toward opportunity, and there is an abundance of that in America." Even during economic downturns or market chaos, Berkshire continued to make large-scale capital expenditures within the United States. This persistent pursuit of opportunities, rather than reactions to macro noise, constitutes the core characteristic of its capital allocation.
