Following the merger and substantial new capital deposits on January 1, 1962, the consolidated BPL launched the new year with $7.18 million in net assets.
BPL's capital allocation was highlighted by the accumulation of a controlling 70% stake in Dempster Mill Manufacturing Company, which grew to represent more than a fifth of BPL's total assets.

[!NOTE] BPL's controlling block of Dempster Mill represented exactly 21.00% of total partnership assets. Buffett valued the holding at $35.00 per share, representing a significant discount to book value ($75.00) and working capital ($50.00) to maintain conservative accounting.
🏢 Note on Control Situations
The partnership's primary control situation in 1961 was Dempster Mill Manufacturing Company of Beatrice, Nebraska. BPL initially acquired Dempster shares five years prior as an undervalued general. After a block became available, Buffett joined the board and eventually acquired majority control in August 1961. BPL owned 70% of Dempster's stock at year-end (with associates holding another 10%). Because the stock had a non-existent public market, Buffett valued BPL's stake at a conservative $35.00 per share (against a cost of ~$28.00).
💡 4. Strategic Context from the 1961 Letter to Partners
Warren Buffett's 1961 letter details key organizational changes and capital allocation rules:
The Great Consolidation
Buffett merged the separate predecessor partnerships (Buffett Associates, Buffett Fund, Dacee, Emdee, Glenoff, Mo-Buff, and Underwood) into one unified vehicle, Buffett Partnership, Ltd. This consolidation lowered administrative overhead and streamlined investment execution. Under the new agreement, profits are allocated with a 6% hurdle rate to limited partners, with any excess divided 25% to the General Partner and 75% to limited partners.
Purchase-Price Discipline
Buffett articulated a core value-investing principle:
"Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good results." Buffett argued that investment success depends on discipline at the point of purchase, ensuring a built-in margin of safety that does not require an optimistic sale price to generate attractive profits.
Operational Infrastructure
To support the growing assets, the partnership moved its headquarters from Buffett's home to 810 Kiewit Plaza in Omaha. BPL also added its first associate, Bill Scott, and a secretary, Beth Henley.
Capital Alignment
Buffett highlighted his personal commitment to the partnership. To ensure complete alignment, Buffett and his wife Susie invested $1,025,000 in BPL, and his relatives held another $782,600, representing virtually their entire family net worth. Buffett also committed that BPL would be his sole vehicle for marketable security investments.
