Marsh & McLennan Cos. (MMC) unit Mercer and Callan Associates mutually agreed to call off the planned marriage of their investment-consulting businesses.

The deal, announced in February and originally set to close this quarter, would have nearly doubled benefits-consulting company Mercer's U.S. presence and given Callan access to international client services.

The companies didn't give a reason for ending the deal.

Though both companies have a strong focus on retirement benefits, Mercer had said the two organizations have very little overlap and it touted the strategic nature of the deal when it was announced. The acquisition received antitrust approval earlier this month.

Mercer, with 18,000 employees globally, has about 200 based in the U.S. Callan focuses solely on the U.S. and employs more than 170 people.
