NEW YORK, March 1 (Reuters) - The U.S. government threw a new $30 billion lifeline to American International Group Inc (AIG.N) on Sunday as the embattled insurer prepared to report the biggest quarterly loss in corporate history.

AIG's board approved a new rescue package that also includes more lenient terms on a government investment in its preferred shares and a lower interest rate on a government credit line, two sources familiar with the matter said.

Details will be announced on Monday when AIG is expected to report a fourth-quarter loss of about $60 billion -- roughly $460,000 per minute.

This would be the third time the government has had to step in to save AIG, once the biggest insurer by market value whose global reach may have made it too big to fail.

A source familiar with the matter said on Sunday night that U.S. authorities felt it was cheaper to put more taxpayer money into AIG than to take the risk of letting it fail.

Allowing the collapse of AIG, which has struggled to sell assets, would have far-reaching consequences for the global financial system as the company guarantees about $300 billion of asset-backed securities and other debt, analysts have said. [ID:nN01331741])

The source told Reuters that a failure of AIG would be both a systemic risk for the U.S. economy and would send shockwaves through the retail insurance industry, adding that as long as it remains a systemic risk, more government help may be needed.

The government has been blamed by many for exacerbating the financial crisis by allowing Lehman Brothers to fail.

"The government really does not have the option of letting AIG totally blow up," said Robert Haines, senior insurance analyst at CreditSights. "The counterparties on most of the book are (European) banks that would be hammered if the U.S. walked away. Hopefully, the third bailout will be the charm."

The rejigged bailout, which changes the terms of an earlier $150 billion rescue, is the latest example of how federal authorities are having to revamp aid for top financial institutions as the global financial crisis deepens.

Last week, the government agreed to boost its equity stake in Citigroup Inc (C.N) to as much as 36 percent in a bid to bolster the bank, already the recipient of billions of dollars in taxpayer funds.

DEBT TO EQUITY

Under the deal, the interest rate on AIG's credit line from the government would be cut to match the three-month London Interbank Offered Rate (Libor), now about 1.26 percent, the sources said. This would save AIG about $1 billion a year.

AIG now pays 3 percentage points above three-month Libor on the $60 billion credit line.

The additional equity commitment, which will be funded from the $700 billion Troubled Asset Relief Program, would give AIG the ability to issue preferred stock to the government later, the sources said.

AIG will also give the Federal Reserve a preferred-stock interest in its American Life Insurance Co (Alico), which generates more than half its revenue from Japan, and Hong Kong-based life insurance group American International Assurance Co (AIA) in return for reducing its debt, they said.

The two businesses will be transferred into separate trusts, but AIG will still own the common equity, one of the two sources said. The government will likely get a 5 percent cumulative dividend on its preferred-share stake in these trusts, the source with direct knowledge of the matter said.

AIG had been trying to sell Alico and part of AIA. Sales of these assets are still a possibility, with some bids already received, the source said.

A second option under consideration is to take these units public when markets improve, the source added.

AIG may also securitize some U.S. life insurance policies and give them to the government to further reduce its debt, the sources said.

The company may securitize up to $10 billion under that plan, one source said.

The debt-to-equity swap and securitizations could help AIG repay much of the roughly $38 billion it has drawn from its government credit line, that source said.

SPINOFF FOR PROPERTY-CASUALTY

Last year, AIG said it planned to sell all assets except its U.S. property and casualty business, foreign general insurance and an ownership interest in some foreign life operations, to pay back the government.

While the company has announced some sales, it has found it difficult to find buyers and get a good price for assets amid the financial crisis.

AIG now plans to spin off up to 20 percent of the property-casualty business in an initial public offering and eventually could spin off the business entirely, one source said.

The business would be renamed to differentiate it from AIG, and have its own management and board of directors.

To aid the auction of at least one major asset, the government could help potential buyers of aircraft lessor International Lease Finance Corp with financing, sources said.

ILFC has some debt coming due in 2009 and, if needed, AIG could use its new equity commitment to help potential buyers with that, one of the sources said.

An AIG spokeswoman did not respond to requests for comment.

MASSIVE LOSS

The deal was reached as AIG prepared to report a massive quarterly loss that would include up to $25 billion in investment losses, about $20 billion in writedowns and up to $15 billion in restructuring charges, one source said.

The revised bailout would allow AIG to avoid a credit ratings downgrade that could have had serious ramifications for the insurer's liquidity and hurt its business.

Customers could, for instance, cancel their insurance policies if a minimum rating was no longer maintained.

Moody's Investors Service and Standard & Poor's both have AIG on review for downgrade from the seventh highest investment grade, and have said the government's support was keeping the ratings from being cut to "junk" status.

AIG, which had 74 million customers at end-2007, has said it has been losing business and finding it harder to win new clients since it was first rescued in September after bad mortgage bets left it on the verge of collapse. [ID:nN27392851])

The government stepped in at the time with an $85 billion bailout, and subsequently offered additional financing, bringing the support up to about $123 billion. In November, the government had to revise its bailout package, raising its total aid to about $150 billion.

AIG shares closed at 42 cents on Friday. The shares have lost 99 percent of their value over the past 12 months. (Additional reporting by Walden Siew, Kristina Cooke and Glenn Somerville) (Editing by Ted Kerr & Ian Geoghegan) * For more M&A news and our DealZone blog, click: www.reuters.com/deals
