Markit Ltd.and IHS said in a Form 6-K filed April 5 that they conducted a preliminary reviewof the new U.S. Treasury rules and expect that the new rules would not result inthe merger transactionbeing subject to U.S. Code 7874.

The companies believe that the other U.S. Treasury rule changeswill not impact the combined company's adjusted effective tax rate guidance of alow- to mid-20s percentage range.

The U.S. Department of the Treasury and the Internal RevenueService on April 4 issued temporary and proposed regulations to limit the numberof corporate tax inversions, including by addressing earnings stripping. By undertakingan inversion transaction, companies move their tax residence overseas to avoid U.S.taxes without making significant changes in their business operations.

The department said it is taking action to limit inversions bydisregarding foreign parent stock attributable to recent inversions or acquisitionsof U.S. companies to prevent a foreign company that acquires multiple American companiesin stock-based transactions from using the resulting increase in size to avoid thecurrent inversion thresholds, required by section 7874, for a subsequent U.S. acquisition.
