This report synthesizes the Buffett Partnership Ltd.’s (BPL) year-end 1964 capital structure and investment allocations, combining details from Warren Buffett’s 1964 Letter to Limited Partners and historical partnership accounts.
🏛️ Executive Summary: The Final Evolution of the Partnership Framework
The year 1964 was a watershed period for the Buffett Partnership, Ltd. BPL achieved a 27.8% return before allocations to the General Partner, outperforming the Dow Jones Industrial Average (which returned 18.7% including dividends) by 9.1 percentage points. By year-end, combined partnership net assets reached a record $26.07 million, representing compounding growth from the initial $105,100 in AUM in 1956.
Strategically, 1964 marked the final evolution of Buffett’s partnership-era investment framework. He expanded his asset classification from three categories to four, introducing "Generals — Relatively Undervalued" to represent large-cap, high-quality companies selling cheap relative to peers. BPL also executed its largest concentrated position to date, allocating approximately 40% of its capital to American Express following the "salad oil scandal." Furthermore, BPL continued its aggressive accumulation of Berkshire Hathaway shares, preparing to take majority control in early 1965.

💡 4. Strategic Context from the 1964 Letter to Partners
Warren Buffett's 1964 letter details key insights into BPL's capital allocation and investment principles:
Introduction of the Fourth Category
Buffett expanded BPL's taxonomy by adding "Generals — Relatively Undervalued." This category focused on large-cap, high-quality companies selling at cheap multiples relative to their industry peers. This marked the early stage of Buffett's transition from pure Graham-style asset cheapness (buying below liquidation value) toward Munger-style relative quality.
Maximizing Gains vs. Tax Minimization
Buffett clarified BPL's tax philosophy: the goal is to maximize net investment returns, not to minimize taxes. He argued that refusing to sell an overvalued stock simply to avoid capital gains tax is a "nullification of investment management." He criticized swap funds (like Federal Street and Westminster) as object lessons proving that tax-avoidance mandates distort investment decisions and destroy performance.
Refusing to Diversify (Ground Rule 7)
Buffett defended his policy of portfolio concentration, codifying Ground Rule 7. He argued that BPL is willing to invest up to 40% of its capital in a single security if the probability of success is extremely high. He mocked the standard institutional practice of buying "two of everything" (the "Noah School" of investing), stating it creates a "zoo" portfolio of diluted quality.
Accepting Illiquidity for Value
Buffett discussed BPL's investment in Mid-Continent Tab Card Co., an unmarketable local company held since 1960. He argued that if a business is purchased at a cheap price, the lack of a daily stock quote is an advantage, forcing the investor to focus on underlying business performance rather than market fluctuations.
