At the center of the scheme is Ingenix, the nation's provider of health care billing information, which serves as a conduit for rate data to the largest insurers in the country, Cuomo said in a statement.
"The U.S. economy is diverse and resilient, and our long-term fundamentals are healthy. I believe our economy will continue to grow, although at a slower pace than we have seen in recent years," Paulson said in prepared testimony to the U.S. House of Representatives Budget Committee.
President George W. Bush on Wednesday is expected to sign into law a $152 billion fiscal stimulus package that will provide tax rebates to some 130 million Americans, with most about $600 for an individual and $1,200 for a couple.
Paulson said the Internal Revenue Service would simultaneously manage the spring tax filing season and preparations for issuing the rebate payments starting in early May.
"Payments will be largely completed this summer, putting cash in the hands of millions of Americans at a time when our economy is experiencing slower growth," he said. "Together, the payments to individuals and the incentives for businesses will help create more than half a million jobs by the end of this year."
Paulson also called on Congress to aid the housing sector by passing legislation that will modernize the Federal Housing Administration and create a new, stronger regulator for Fannie Mae and Freddie Mac, the government-sponsored housing finance enterprises.
Cuomo said he plans to sue Minnetonka, Minnesota-based UnitedHealth, the largest U.S. health insurer, over deceptive practices in the reimbursement policy it links to such charges, which he claims seriously shortchange patients and involve a conflict of interest.
``When insurers like United create convoluted and dishonest systems for determining the rate of reimbursement, real people get stuck with excessive bills and are less likely to seek the care they need,'' Cuomo said in a statement today.
Cuomo said he will subpoena UnitedHealth, Aetna Inc., Cigna Corp. and Empire Blue Cross & Blue Shield over their reimbursement practices.
UnitedHealth's Ingenix unit provides data that sets ``reasonable and customary'' rates, which put a ceiling on reimbursement to patients, Cuomo said. When patients go out of network, health insurance companies generally cover only 80 percent of `reasonable and customary' charges.
Cuomo said a six-month investigation showed Ingenix has a ``defective and manipulated'' database that most health insurance companies use to set reimbursement rates for out-of-network expenses. The probe found that two subsidiaries of United ``dramatically under-reimbursed'' patients for out-of-network expenses using information from Ingenix.
United Falls
UnitedHealth fell $2.28, or 4.7 percent, to $45.99 at 12:02 p.m. in New York Stock Exchange composite trading.
``This is obviously going to be a negative for the company,'' said Sheryl Skolnick, an analyst with CRT Capital Group in Stamford, Connecticut, in a telephone interview. ``These things typically take a long time to work their way through. It does make it more difficult for United to argue that they have fixed their challenges.''
UnitedHealth Group Inc., WellPoint Inc., Aetna Inc. and other health insurers fell in New York trading this morning in anticipation of Cuomo's announcement.
Don Nathan, a spokesman for UnitedHealth, had no comment before the announcement.
The local currency was trading at R7.71 to the dollar at 17:44 GMT, 0.9% stronger than its previous close in New York, after see-sawing between R7.6775 and R7.82 during the session.
Government bonds tracked the rand's move in relatively light trade, pulling back some of their sizable losses sparked by investor concern over an expected easing in economic growth.
Dealers said trade was largely flow-driven with dollar buying out of London early in the day paring gains before it drifted back on higher stocks and broader emerging market gains as those flows waned.
"Emerging markets are stronger, the dollar is weaker against the euro and local stocks are up on the Dow (Jones index) and we are just picking up that on the currency," ABN AMRO trader Paul Peter said.
Gold fell as much as 1% as the dollar gained ground versus the euro after Warren Buffett told CNBC television that he had offered to take over the liabilities of monoline bond insurers. But the metal later pared losses.
Platinum rose to a high of $1 965 an ounce before falling to $1 943/1 950 by 17:50, against $1 933/1 941 in New York late on Monday.
"You know that platinum demand is increasing on the back of emission controls and you know that supplies are going to be squeezed. So it just makes sense to be long in this market," said Johannesburg-based Walter De Wet, analyst at Standard Bank.
"There might be slight over-reaction as everybody is on the bandwagon because of the recent price rise, but there is also some realisation that things are going to get tighter. We believe that the bias is on the upside."
Platinum's rally, which has sent prices up 30% in just three weeks, gained pace after Anglo Platinum, the world's biggest producer, said on Monday the power problem alone would cut output by as much as 120 000 ounces in 2008. It had already cost 30 000 ounces in lost output this year.
Northam Platinum said on Tuesday its production fell 16.5% to 150 755 ounces the July-December period of 2007 from a year earlier and saw its output at the same level in the next six months, provided mines got 90% power.
The market nervously awaits financial results of Impala Platinum, the world's second-biggest producer of the metal, on Thursday for more cues on total production losses.
"It's a chronic problem. It has been a deficit market for many years and it looks like it has returned to a significant deficit market again," said David Holmes, director of metals sales at Dresdner Kleinwort Investment Bank.
Mines across South Africa, which accounts for four-fifths of the world's supply of the metal, ground to a halt for five days at the height of the power crisis last month. Platinum is used in jewellery and auto catalysts to clean exhaust fumes.
Negotiations were under way for South African state-owned power utility Eskom to buy surplus electricity from local producers as part of its bid to solve the nation's energy crisis, Public Enterprises Minister Alec Erwin said on Monday.
The investment committee of Washington state's pension fund, which met with TPG co-founder David Bonderman Feb. 7, will recommend a $750 million commitment, said Liz Mendizabal, a spokeswoman in Olympia. Bonderman is set to discuss the fund, called TPG VI, with the Oregon Investment Council Feb. 27.
TPG, based in Fort Worth, Texas, is putting together the fund even as deal-making is stalled after a doubling of financing costs in the second half of 2007. Endowments and pension funds, seeking returns that top stocks and bonds, are increasing their investments with private-equity firms, whose assets may reach $5 trillion by 2012, according to research firm Private Equity Intelligence Ltd. in London.
``The public markets are down or soft and there's no other game,'' said Lyons Brewer, a managing director of C.P. Eaton Partners LLC, a Rowayton, Connecticut-based firm that helps buyout firms and hedge funds raise money.
Funds raised a record $502 billion last year, according to Private Equity Intelligence, including $21.7 billion by New York-based Blackstone Group LP, the industry's biggest pool.
Any losses by the unit that issues so-called credit-default swaps won't be material to AIG, the firm said today in a statement. AIG rebounded in New York trading after falling the most in two decades yesterday on disclosure that writedowns from the contracts, sold to protect fixed-income investors, were four times bigger than a previous estimate.
Chief Executive Officer Martin Sullivan, who manages units that originate, insure and invest in subprime mortgages or securities, assured investors in December that writedowns tied to the U.S. housing market were ``manageable.'' The company, based in New York, has said it doesn't expect to sell mortgage- related investments at a loss when markets are weak.
While AIG ``may have illustrated questionable judgment'' in its accounting lapse, it ``does not necessarily increase the probability of real economic impairment'' on assets held to maturity, said Mark Lane, analyst at William Blair & Co. in Chicago, today in a research note. He rates the company ``outperform.''
AIG advanced $1.45, or 3.2 percent, to $46.19 at 12:48 p.m. in New York Stock Exchange composite trading. The company has lost about 33 percent in the past 12 months, trailing the 5.7 percent decline of the Standard & Poor's 500 Index.
`Solid Upside'
``For patient investors willing to ride out near-term volatility, we see solid upside in the stock,'' said Morgan Stanley analyst Nigel Dally in a note to investors today. He rates the company ``overweight.''
The insurer's financial products unit issues contracts that promise to reimburse investors for losses tied to $505.5 billion of securities as of Nov. 25, including corporate debt, European mortgages and collateralized debt obligations, which bundle together loans.
