These amounts include estimated losses and loss expenses net of reinsurance recoverable and also include estimated reinsurance reinstatement premiums. Of the pre-tax losses, approximately $200 million represents Chubb’s estimate for losses from U.S. catastrophes, of which $125 million was from the March Northeast U.S. storm. Losses from catastrophes outside the U.S. amounted to approximately $90 million pre-tax, of which $70 million was from the Chilean earthquake.
