NEW YORK (AP) – The builders of the World Trade Center site have settled all outstanding legal battles with dozens of insurers over the multibillion-dollar policy on the former trade center, state officials said Wednesday.

Governor Spitzer and state Insurance Superintendent Eric Dinallo were to announce details of the settlement at an afternoon news conference, said Dinallo’s spokesman David Neustadt.

“Everybody made concessions,” Mr. Neustadt said.

Part of the agreement reached means that trade center developer Larry Silverstein and the Port Authority of New York and New Jersey – the site’s owner – will get a little less than the $4.6 billion in insurance proceeds that Silverstein was awarded after a 2004 trial, Mr. Neustadt said.

The Port Authority, Silverstein and the insurers would not comment ahead of the announcement. Allianz Global Risks U.S. Insurance Co. and the former Royal Indemnity Co., two insurers which had recently not agreed to pay their parts of payments to both Silverstein and the Port Authority, did not immediately return messages seeking comment.

Since the Sept. 11, 2001, terrorist attacks that destroyed the trade center, Silverstein and the Port Authority planned to use the insurance money to help rebuild the 16-acre site’s office and retail space with the 1,776-foot Freedom Tower and four other buildings.

Mr. Silverstein went to court with all of the insurers in 2004, arguing that his $3.5 billion policy should be doubled because the two hijacked planes that crashed into the towers represented two attacks instead of one.

Mr. Silverstein was awarded $4.6 billion in 2004. Two juries determined he was entitled to an extra $1.1 billion because the companies’ different insurance policies carried different wording about what would constitute multiple events.

The insurers have been recently in court to determine exactly how much they should pay.

Mr. Silverstein was originally responsible for rebuilding all five towers, but a year ago agreed to split the rebuilding – and the insurance money – with the Port Authority, which will build the Freedom Tower and another planned tower.

The Port Authority and Silverstein sued several insurers this year who refused to recognize the agreement. The insurers involved include Swiss Reinsurance Co., which holds the largest policy on the trade center, Zurich American Insurance Co., Travelers Indemnity Co. and Employers Insurance of Wausau.
