Munger, Tolles & Olson LLP represented Berkshire Hathaway Inc. in its definitive agreement to acquire The Lubrizol Corporation in an all-cash transaction. The deal was announced on March 14, 2011 and is valued at approximately $9.7 billion, including approximately $0.7 billion in net debt, making it one of the largest acquisitions in Berkshire Hathaway history.

“Lubrizol is exactly the sort of company with which we love to partner – the global leader in several market applications run by a talented CEO, James Hambrick,” said Warren Buffett, Berkshire Hathaway chief executive officer.

Attorneys working on the matter include Robert E. Denham, Mary Ann Todd, Stephen D. Rose, Henry E. Orren and Anne Henry Lee.

MTO has represented Berkshire Hathaway in a variety of deals including its February 2011 agreement to acquire the shares of Wesco Financial Corporation it doesn’t already own and the landmark $44 billion acquisition of Burlington Northern Santa Fe Corp., which closed in February 2010.
