????Another downer for Berkshire's profits in 2011 was the failure of the housing industry to rebound. A relative optimist a year ago about housing, Buffett admits now to having been "dead wrong."
????Berkshire owns not only the largest producer of homes in the U.S. -- Clayton Homes, which manufactures housing -- but also four other housing-related businesses: Acme Brick, Shaw (carpets), Johns Manville (insulation), and Mitek (building products). Together, these businesses had $1.8 billion in pre-tax profits back in 2006. In 2011, pre-tax profits were a measly $513 million.
????Right now, Buffett views housing as still stuck in its own special "depression." But he believes the situation is easing steadily and that the industry will make a comeback consistent with that already visible in most other sectors of the economy.
????On the good-news front, Buffett gave a new label to Berkshire's largest non-insurance businesses, calling them the "fabulous five." They are BNSF, Iscar, Lubrizol, Marmon Group, and MidAmerican Energy. Their combined pre-tax earnings in 2011 were more than $9 billion (though that includes more than half a year of Lubrizol profits that were earned before Berkshire bought Lubrizol in September). Buffett says in his letter that he expects each of the five to set a new profit record this year.
????BNSF, one of the nation's largest railroads, has been a star since it was purchased by Berkshire in early 2010. Its pre-tax profits last year were $4.74 billion, up from about $4 billion in 2010, a gain of more than 18%.
