Tyco International, which plans to split into three companies in coming weeks, reported lower quarterly earnings as restructuring costs reduced earnings, but results beat Wall Street expectations thanks to a low tax rate.

Tyco said it still aims to complete its break-up by the end of June, but could not set a definitive date while waiting for a response from regulators to its recent filings. The company plans investor roadshows for each of the three companies in the two weeks before the split-up.
