Okay, here's what I've since found out.
The $3.5 billion coverage was for all four of the buildings under the July 2001 lease (buildings 1, 2, 4 and 5).
The coverage was procured through 23-24 insurance companies.
Two companies - ACE Bermuda and XL Insurance, Ltd. - settled in Feb. 2002, paying a total of
$365 million ($298 million by ACE and $67 by XL)
Three companies - Hartford, Royal Indemnity, and St. Paul Fire - brought motions for summary judgment seeking a declaration that they were subject to the "WilProp" language (which would mean that the terrorist attacks were one occurrence and not two) rather than the Travelers language. They were successful and the decision was upheld on appeal by the Circuit Court in September 2003. These three were subject, therefore, to a maximum liability of
$112 million.
The remaining insurers were split into two groups for jury trials on the question of whether they were subject to the "one occurrence" or "two occurrence" language.
The first trial resulted in a verdict that 10 of those insurers whose liability totalled $1.9 billion, were subject to the WilProp language and thus their total liability was limited to
$1.9 billion (three of the 13 insurers in this group were found to be liable to the "two occurrence" language so were added to the second trial group).
The second trial resulted in a verdict that the remaining insurers were indeed subject to the double occurrence language, so their $1.1 billion in coverage resulted in these insurers being liable for a maximum of
$2.2 billion
Total potential payout, therefore, is capped at
$4,577,000,000 for buildings 1, 2, 4, and 5.
I'm still looking for info on WTC7 but thought I'd post this now.
