"From my perspective, I was having a sense we were beginning to fall back into the same kind of rhetoric we were hearing for the past several years," Mr. Iuppa said. "So, I thought it was time we throw a fastball instead of a slider and move the discussion forward."

As for where he thinks they are now in the overall process, "I would say we are at second base in the bottom of the fifth."

However, to primary industry representatives such as the American Insurance Association's assistant vice president, David Snyder, the move was a sellout of the U.S. consumer for no apparent reason. "When you sell someone down the river, you should at least get something in return," he said.

An Interested Parties group will now work to flesh out and revise the proposed new rating system in time for final Task Force action in December--and ultimately full NAIC approval not long after that.

The proposal now in play will create some yet-to-be-determined mechanism to rate all reinsurers--alien or domestic--to determine what percentage of collateral they must post to operate in this country. It came from a so-called ad hoc group of commissioners formed several years ago to come up with collateral alternatives after the initial three years of debate failed to reach any consensus.

Mike Koziol, assistant vice president of the Property Casualty Insurers Association of America, said the rating proposal could in theory offer the same solvency protection as the current system, but it was currently so amorphous as to be almost meaningless.

Mr. Iuppa said regulators would work with interested parties to "resolve any questions as to exactly what we are looking for in the next couple of weeks"--but emphasized he would make every effort "to make sure the rhetoric does not escalate to where it was before."

Many in the domestic industry have resisted changes to the collateral rule, arguing there is no reason to "reform" the rules since the present system is working fine. "This action is inexplicable in that it harms U.S. consumers and insurance companies, and benefits only selected foreign reinsurers," Mr. Snyder said. "The winners are influential economic interests outside the U.S."

Many industry officials had been expecting some recommendation for halfway measures to replace collateral requirements that could be approved by December, with further discussions on the overall question to follow.

The 100-odd member Interested Party group presented a 45-page PowerPoint presentation at the June 10 NAIC meeting that its representatives admitted could not even be close to being called a consensus--but it outlined numerous alternatives with the pros and cons of each.

"It is almost as if 27 hours of meetings has now gone down the drain," said PCI's Mr. Koziol, who expected this work product to be winnowed down at the session for further discussion. Instead, one proposal that predated this group's discussions is now in play.

The new rating entity could in theory be any National Rated Standards Rating Organization such as Fitch or A.M. Best., or a new NAIC-related entity such as the Securities Valuation Office.

Whatever it is, the standards by which reinsurers will now be rated must be worked out, which could be a long and drawn-out process. After final approval, the Credit For Reinsurance Model Act would have to be amended both at the NAIC level and in individual states--which could take years, since the model is an accreditation standard.

Until that happens, Mr. Koziol said a state regulator could in theory challenge the authority of the new agency to hold sway in their state.

Since about 2000, alien reinsurers--including Lloyd's of London and companies that are part of the International Underwriters Association--have pressed for regulators to reduce the 100 percent collateral they were forced to post for potential claims after an event, maintaining that the great majority were from well-regulated countries and should not be judged too great a risk merely because they are from a foreign domicile.

However, the domestic insurance industry had successfully held back any change with the argument that differing accounting standards had made judging companies too risky, and that collateral requirements were the only adequate means to assure primary companies their reinsurance obligations could be met.

The adversaries took a nearly three-year break in an ultimately futile effort to reach a compromise. In the interim, efforts have moved forward to harmonize U.S. and foreign accounting standards, while European regulation was growing increasingly standardized through European Union auspices.

The International Association of Insurance Supervisors, in which Mr. Iuppa plays a leading role, has also assumed a new prominence in promoting more global regulatory harmonization.

However, while virtually all players realized some change was inevitable, there was a sharp degree of difference over how much change was needed and how soon it had to be made. Those differences won't die down in the coming six months, as the Task Force could in theory reverse itself and maintain the status quo.

Opinions here differed as to the likelihood of that happening, but the vehemence and anger of those who might be termed the losers in this question indicated a major change is now almost inevitable.
