From CNN  Money.com:
 
Senate Finance Committee staff Wednesday  sought comment on draft legislation that would tax related-party transactions  by Bermuda-based insurance companies.
U.S. insurers including W.R. Berkeley  Corp. (WRB), the Chubb Corp. (CB), and the Travelers Companies (TRV)  have long charged that the Bermuda firms avoid taxes on their U.S. business  by reinsuring the risk to the Bermuda parent.
The U.S. subsidiaries of firms including  the ACE Group (ACE) and XL Capital Ltd. (XL) can then deduct the reinsurance  premiums, lowering their U.S. tax liability. The Bermuda affiliate doesn't  pay U.S. tax on the premium, while earning investment income subject  to little or no tax.
"Thus, it is an efficient way of  significantly reducing U.S. tax without transferring risk," according  to a Finance Committee statement accompanying the draft legislation.
