End in sight to subprime mortgage writedowns: S&P

By Dena Aubin

NEW YORK (Reuters) - Standard & Poor's said on Thursday write-downs for large financial institutions on subprime debt are likely past the halfway mark, but could still hit $285 billion.

S&P's estimate of write-downs was up from the $265 billion figure it published in January, but the credit ratings agency said an end to subprime write-downs was in sight.

"The positive news is that, in our opinion, the global financial sector appears to have already disclosed the majority of valuation write-downs of subprime asset-backed securities," S&P credit analyst Scott Bugie said in a report.

More write-downs could be in store outside the subprime sector, however, S&P cautioned.

S&P's statement gave a boost to financial stocks and helped Wall Street indexes pare losses.

The Dow Jones industrial average .DJI gained 0.3 percent after earlier falling about 2 percent. The S&P 500 Index .SPX was up 0.88 percent, reversing earlier losses of more than 2 percent.

LEHMAN, MERRILL SHARES RISE

The Amex Securities Broker/Dealer index .XBD, which includes investment banks and brokerages, shed nearly 5 percent before the report. It ended up 1.0 percent.

"We believe that the largest players, such as Merrill Lynch & Co Inc MER.N and Citigroup Inc (C.N), have rigorously and conservatively valued their exposures to subprime asset-backed securities such that most of the damage should be behind them," S&P said.

S&P also said some subprime mortgage write-downs are larger than any reasonable estimate of actual losses.

Shares of Lehman Brothers Holdings Inc LEH.N, down nearly 5 percent before the S&P report, reversed those losses and ended up 2.3 percent $45.99.

Shares of Merrill Lynch, which had been down 2.5 percent, ended up 2.98 percent.

Some market players may have misread S&P's report, however, said Daniel Alpert, managing director at Westwood Capital, a New York investment bank specializing in securitization.

The report deals only with expected losses on subprime debt, but that is only about 8 percent of the $11 trillion of total residential mortgage debt outstanding, Alpert said in an e-mail.

"The current crisis, of course, is no longer a subprime crisis," he said, noting that a growing percentage of home foreclosures are coming from outside the subprime sector.
