April 17 (Bloomberg) -- Citigroup Inc., the U.S. bank rescued by $45 billion in U.S. taxpayer funds, ended a five- quarter losing streak with a $1.6 billion profit on trading gains and an accounting benefit for companies in distress.

The first-quarter profit compared with a net loss of $5.11 billion, or $1.02 a share, a year earlier, the New York-based bank said. On a per-share basis, the bank reported an 18-cent loss because of costs related to preferred dividends. The average estimate of 13 analysts surveyed by Bloomberg was a loss of 32 cents.

Citigroup investors hadn’t seen a profit since before Chief Executive Officer Vikram Pandit took over in 2007. While the bank cut compensation costs and took fewer writedowns, it couldn’t halt rising delinquencies on home and credit-card loans. Citigroup benefited from higher fixed-income trading revenue that also bolstered earnings at Goldman Sachs Group Inc. and JPMorgan Chase & Co.

“We’ve seen good trading results from JPMorgan, from Goldman Sachs and now from Citi,” said Gary Townsend, chief executive officer of Hill-Townsend Capital LLC. “There is a question about sustainability, but it’s clearly a good sign for the sector.”

Not a ‘One-Off’

The industry’s first-quarter profits aren’t a “one-off” phenomenon, Barclays Plc President Robert Diamond said in an April 15 interview. “It has been quite a while since we’ve seen analysts talk about revenue as opposed to writedowns and balance-sheet risks,” he said.

Citigroup fell 36 cents, or 9 percent, to $3.65 as of 4:13 p.m. At its peak in late 2006, the stock was worth $56.41, valuing the company at $277 billion. At the current price, the market value stands at about $20 billion.

The bank reported $4.69 billion of fixed-income trading revenue in the quarter, compared with a trading loss of $7.02 billion a year earlier. Stock-trading revenue was $1.9 billion, a 94 percent increase.

The company took $5.62 billion of writedowns on subprime- mortgage-related securities and other investments in its trading division, reflecting a further erosion in their market value. That compared with $14.1 billion of writedowns in the first quarter of 2008, for a positive $8.47 billion revenue swing.

Stress Tests

Citigroup posted a $2.5 billion gain from accounting rules that allow companies to profit when their own creditworthiness declines. The rules reflect the possibility that a company could buy back its own liabilities at a discount, which under traditional accounting methods would result in a profit.

Citigroup already is benefiting from the Financial Accounting Standards Board’s decision earlier this month to ease rules that forced banks to write down assets whose market value had been depressed so long their impairment was no longer considered “temporary.” That rule change reduced impairment charges by $631 million on a pretax basis, the bank said.

Credit-card revenue fell 10 percent to $5.77 billion, while consumer-banking revenue dropped 18 percent to $6.4 billion. The institutional clients group, which includes trading, investment banking and payment processing, had $9.51 billion of revenue, compared with a trading loss of $4.96 billion the prior year.

Revenue from providing retail brokerage and banking to the ultra-wealthy fell 20 percent to $2.62 billion.

Credit Cards

In Citigroup’s credit-card business, costs to cover bad loans and increase reserves for future losses grew 64 percent from a year earlier to $3.09 billion. The bank offset those costs partly by charging customers more: Interest revenue as a percentage of credit-card loans climbed to 13 percent from 11 percent a year earlier.

The quarter’s results included a $250 million gain from releasing reserves that previously had been set aside for potential litigation expenses, Citigroup said. The bank also booked a $110 million tax benefit related to the “resolution of certain issues” in an Internal Revenue Service audit.

The prior year’s quarter included $626 million of net charges, the company said.

Citigroup’s effective tax rate in the quarter dropped to 33 percent, from 43 percent a year earlier.

Citigroup, one of 19 U.S. banks gearing up for the release of so-called stress tests run by the Federal Reserve, has more than tripled on the New York Stock Exchange since falling to an all-time low of $1.02 on March 5, in the wake of the company’s announcement that as much as $52.5 billion of preferred stock would be exchanged for common shares to bolster the bank’s equity base.

Common Equity

Under that plan, as much as $25 billion of the government’s investment in the bank will be converted into regular shares, giving it a 36 percent voting stake. Citigroup’s tangible common equity -- a cushion against losses that many investors and analysts study -- will increase to $81 billion from about $30 billion. Existing shareholders will be left with about a fourth of their original stakes.

The bank said it plans to delay formal offering documents related to the planned preferred-share conversion until after the results of the stress tests are released.

On a conference call with analysts today, Chief Financial Officer Ned Kelly addressed speculation that the company might change the original terms, saying he “can’t envision” that happening. He declined to comment on the tests themselves, saying regulators had ordered him to keep mum on the subject.

Compensation, the bank’s biggest non-interest expense, fell 27 percent to $6.42 billion, as Pandit’s job-reduction plan slashed the workforce by 13,000 employees to 309,000 at the end of March.

Goldman Sachs on April 13 reported better-than-expected earnings as a surge in trading revenue outweighed asset writedowns. Wells Fargo & Co., the second-biggest U.S. home lender, said last week it had about $3 billion in first-quarter net income, up from $2 billion a year earlier. Profit of about 55 cents a share was more than double the average estimate of analysts in a Bloomberg survey.
