The Internal Revenue Service has published figures that insurers based outside the United States need to compute their minimum effectively connected net investment income.

The IRS has posted the information in IRS Revenue Procedure 2010-29.

The figures in the procedure will help insurers comply with Internal Revenue Code Section 842(b), the section that sets the effectively connected net investment income rules, for taxable years beginning after Dec. 31, 2008, officials say.

The Treasury secretary sets separate figures for non-U.S. life insurers and non-U.S. property-casualty insurers.
