Several new insurance companies will enter the second stage of the legal dispute between World Trade Center leaseholder Larry Silverstein and the insurers who provided cover for the complex.

The second stage of the legal process will determine whether those insurers not bound by WilProp were bound by slips which defined the attacks as one event or two.

Following the verdicts announced today, and the remaining pending verdict on lead insurer Swiss Re, the maximum potential recovery by Silverstein is $5.5bn, said his spokesman.

The insurers not involved in the first phase of the trial, meaning those insurers who did not claim they were covered under the WilProp form, are as follows:

Allianz (SCOR) - $355 million per occurrence
IRI - $237.2 million per occurrence
Travelers - $210.6 million per occurrence
Allianz - $77.9 million per occurrence
Gulf - $65 million per occurrence
TIG - $9.1 million per occurrence
Tokio Marine - $1.6 million per occurrence.

They will be joined by Zurich America Insurance Company, Twin City Fire Insurance Company and a unit of Royal & SunAlliance Insurance Group, following the jury's decision that they were not bound by the WilProp form.
