ADP ® and Macroeconomic Advisers, LLC, today announced that Macroeconomic Advisers will no longer partner with ADP in ADP's production of the ADP National Employment Report®, ADP's widely followed monthly gauge of U.S. nonfarm private sector employment. The two companies announced an amicable end to their collaboration on the report.

"After a successful six-year collaboration, we have mutually agreed with Macroeconomic Advisers to part ways as we enter a new era with the ADP National Employment Report," said Jan Siegmund, Chief Strategy Officer and President, Added Value Services for ADP. "We have the highest respect for Macroeconomic Advisers' team, and want to thank them for their partnership and support during the past six years."

We look forward to focusing our energies on our newly launched services that are more directly related to our mission, including our new MacroFinancial Scenarios Service and our updated macro model," said Joel Prakken, Senior Managing Director, Macroeconomic Advisers, LLC. "We wish ADP much continued success with the report."
