Wesco Financial Corporation
1. Origin of Relationship
Wesco Financial Corporation (Wesco) became a subsidiary of Blue Chip Stamps in 1973 when Blue Chip acquired a 54% controlling stake. This acquisition brought Wesco and its subsidiary, Mutual Savings and Loan Association, into Berkshire's orbit, leading to Charlie Munger being appointed Chairman.

3. Strategic Importance
Wesco Financial Corporation served as a mini-Berkshire for decades. Chaired by Charlie Munger, it operated with the same principles of capital allocation: using insurance float (via Wesco's insurance subsidiaries formed later) and savings and loan assets to build a concentrated stock portfolio. Wesco was also a critical vehicle for the Buffett-Munger partnership, demonstrating how non-controlling parent companies could compound capital through semi-autonomous subsidiaries.
