Warren Buffett on Saturday launched a strong defense of Berkshire Hathaway Inc's $5 billion investment in Goldman Sachs Group Inc and the investment bank's embattled chief executive, Lloyd Blankfein.

Speaking at Berkshire's annual meeting, Buffett also said Berkshire swung to a $3.63 billion first-quarter profit, compared with a year-earlier $1.53 billion loss, helped by an improving economy and gains from investments and derivatives.

Buffett said operating earnings rose 30 percent from a year earlier to $2.22 billion from $1.71 billion, helped by a pretty good uptick in activity among Berkshire's roughly 80 operating units.

Berkshire's investment in Goldman preferred shares in September 2008 has become controversial for Buffett, given his long-standing emphasis on good corporate ethics and criticism of Wall Street excess.

Buffett said he did not hold against Goldman the U.S. Securities and Exchange Commission civil fraud lawsuit alleging the bank hid from investors that securities underlying a risky debt transaction were chosen by Paulson & Co, a hedge fund firm that was betting they would lose value.

Goldman has called the charges unfounded, and Paulson was not charged.

News that investigators opened a criminal probe into Goldman has led to increased speculation about Blankfein's job security, but Buffett expressed strong support.

Asked who should run Goldman if Blankfein were replaced, Buffett said: If Lloyd had a twin brother, I would vote for him. I have never given that a thought.

The $5 billion investment consists of preferred shares that throw off $500 million in annual dividends, plus warrants to buy an equal amount of common stock. Goldman can buy back, or call, the preferreds at a premium.


We love the investment, Buffett said. Our preferreds are paying $15 a second, so as we sit here, 'Tick, tick, tick, tick,' that's $15 every second, he said.

Buffett added that the SEC lawsuit was not a serious enough event to raise reputational issues that would call into question the Berkshire investment.

Asked whether Goldman should have disclosed it had received a Wells notice from the SEC indicating possible civil charges, Buffett said such notices are not necessarily material to larger companies such that disclosure is needed.

If it leads to something more serious, then we will look at the situation at that time, he said.

Buffett and Berkshire Vice Chairman Charlie Munger also discussed the potential overhaul of financial regulation now being weighed in Congress.

Munger argued the system should be changed to be less permissive to banks. What we need is a new version of Glass-Steagall, he said, referring to a Great Depression-era law that kept commercial and investment banks separate. It was repealed in 1999.

Berkshire has opposed a provision in proposed legislation that could force it to post more collateral on its roughly 250 derivatives contracts, mainly tied to longer-term performance of stock price indexes.

But Buffett said Berkshire would likely not have to put up a dime because the company is unlikely to be regarded as so dangerous to the system as to require such collateral.

Investments and derivatives generated $1.41 billion of Berkshire's preliminary first-quarter profit, compared with a year-earlier $3.24 billion loss.

Insurance profit fell just 3 percent, while profit in regulated businesses such as utilities and newly acquired Burlington Northern Santa Fe Corp, as well as manufacturing, service & retailing businesses, roughly doubled.

Final results are expected May 7.

2:58 A.M.

Attendance at the meeting is believed to have reached a record 40,000, with only about half of attendees able to fit in the main arena at Qwest Center Omaha. Hundreds lined up to enter prior to its 7 a.m. opening.

I was first in line at this door at 2:58 a.m., said Bill Guenther, 57, a forester from Newfane, Vermont, who said he owns 50 Berkshire Class B shares and was at his first meeting.

I've always been a fan of Warren Buffett, he said. I'm an old-school sort, I'm not a dot-commer, I'm not a techie, I don't even have a TV at home. But I've always admired Warren. He was called a dinosaur during the big dot-com bust, and when all that collapsed, we saw he was doing it the right way.

Before the meeting, Buffett ambled around a nearby exhibit hall featuring Berkshire companies, spending 10 minutes marveling at a model railroad at the Burlington Northern exhibit, and strumming a ukulele as he belted out I've Been Working On The Railroad with The Quebe Sisters Band.

He later picked up his usual vanilla and orange bar at a Dairy Queen stand, but did not pay the $1 he usually does.

We got his donation earlier, the vendor said.

Buffett, 79, is worth $47 billion, Forbes magazine said in March.
