On February 8, 2011, the Pasadena Star-News published the following article regarding the proposed acquisition by Berkshire Hathaway of Wesco:

Berkshire has deal in place to buy Wesco

By Erick Galindo, Staff Writer

PASADENA - Warren Buffett’s Berkshire Hathaway announced Monday that it will assume full ownership of Pasadena-based Wesco Financial Corp.

Wesco spokesman Jeffrey Jacobson said the move will solidify the two companies’ long-standing relationship and simplify some of the bookkeeping.

“This will take Wesco from being a publicly owned company to a wholly owned subsidiary,” Jacobson explained. “From a financial accounting standpoint, it will simplify the year-to year reporting.”

Omaha-based Berkshire has owned 80.1 percent of Wesco since 1983 and will acquire the remaining shares of Wesco’s common stock for about $547.6 million.

The deal is expected to be completed before the end of the second quarter. It still requires approval from the holders of the outstanding 1.4 million shares of Wesco, who will have the option of taking cash or shares of Berkshire Class B common stock.

Wesco, which operates out of a nine-story office building on Colorado Boulevard, is a conglomerate that owns insurance businesses and an eclectic mix of operating companies that employ more than 250 people.

The merger was expected since at least September, after a proposal from Berkshire made to the Wesco board of directors.

In a statement, the company said it formed a special committee of independent directors, which determined the deal to be “fair to and in the best interests of Wesco and its shareholders.”

The deal values Wesco’s shares at $386.55 each, but the estimated value of Wesco’s stock will be adjusted based on its value when the deal closes. Updates will be posted online at www.wescofinancial.com.

Wesco stock closed up $6.83 Monday to $387.50. Berkshire’s Class B shares gained 93 cents to $84.10.

Wesco Chairman and CEO Charlie Munger, who is also Berkshire’s vice chairman, declined to comment on the deal. Munger is Buffett’s longtime friend and business partner.

Wesco expects that if the merger is consummated before June, there will be no annual meeting of Wesco’s shareholders. The meetings have been highly popular among shareholders.

Munger said he will hold an “Afternoon with Charlie” event in Pasadena within a few weeks after the merger to give Berkshire and former Wesco shareholders a chance to ask him questions about business, economics and life, but not about Wesco.
