OMAHA, Neb. (AP) -- Billionaire investor Warren Buffett said Saturday that he was "dead wrong" with a prediction that the U.S. housing market would begin to recover by now, but he remains optimistic about the nation's economy.
In his annual letter to Berkshire Hathaway shareholders, Buffett said he is sure housing will recover eventually and help bring down the nation's unemployment rate. But he did not predict when that will happen.
Investors eagerly await the letter from Buffett, 81, the so-called Oracle of Omaha, who built a roughly $44 billion fortune by following a steadfast, no-nonsense investing strategy.
Buffett said housing "remains in a depression of its own," but he predicted, in typical plainspoken style, that the housing market will come back because some human factors can't be denied forever.
"People may postpone hitching up during uncertain times, but eventually hormones take over," he wrote. "And while 'doubling-up' may be the initial reaction of some during a recession, living with in-laws can quickly lose its allure."
The housing prediction proved painful for Berkshire Hathaway. It owns more than 80 subsidiaries, including the Geico insurance company and See's Candy, and five of them depend on construction activity.
Those businesses, which include Acme Brick, Clayton Homes and Shaw carpet, generated pre-tax profits of $513 million last year. That's well off the $1.8 billion those companies added to Berkshire in 2006.
Berkshire's insurance companies took $1.7 billion in catastrophe losses last year, including from the earthquake and tsunami in Japan. Berkshire reported only $154 million in underwriting profit, down from $1.3 billion the previous year.
But several of Berkshire's larger non-insurance businesses — Burlington Northern Santa Fe railroad, MidAmerican Energy, Marmon Group, Lubrizol and Iscar — all generated record earnings in 2011.
That helped Berkshire as a whole to generate $10.3 billion in net income, or $6,215 per Class A share, last year, down from nearly $13 billion, or $7,928 per share, in 2010.
A Class A share of Berkshire stock, which has never been split by the company, traded for $120,000 on Friday. Its more affordable Class B shares traded for about $80.
Buffett reassured Berkshire shareholders that the company has someone in mind to replace him eventually, but did not name the successor. He emphasized that he has no plans to leave.
Glenn Tongue, a managing partner at T2Partners investment firm, said he was struck by the fact that Buffett chose to deal with the succession topic as one of the first items in his letter.
"I think this was a forceful and stronger attempt to put this issue to bed," Tongue said.
Buffett offered a couple of details about Berkshire's succession planning in this year's letter. Investors have long worried about who will replace Buffett as Berkshire chairman and CEO.
Buffett said the Berkshire board is enthusiastic about the executive it has picked and said there are two good back-up candidates.
"When a transfer of responsibility is required, it will be seamless, and Berkshire's prospects will remain bright," Buffett said.
Previously, Buffett had said only that the board had three internal candidates for the CEO job. Berkshire plans to split Buffett's jobs into three parts to replace him with a CEO, a chairman and several investment managers.
Berkshire has also cleared up some succession questions by hiring two hedge fund managers, Todd Combs and Ted Weschler. Buffett says those two have the "brains, judgment and character" to manage Berkshire's entire portfolio eventually.
