SC Johnson has put its global media-buying duties up for review.

Word of the review -- first reported by Adweek.com Friday afternoon, and confirmed separately by sources familiar with the situation -- follows the company’s January decision to award Omnicom Media Group’s PHD global communications planning duties after a review that also included the media-buying incumbent Maxus, part of WPP.  

The planning assignment covers approximately $300 million in brand expenditures and is managed out of PHD’s Chicago office.

The broader buying assignment is significantly bigger. Estimates for the company's global spend have been as high as an estimated $1 billion in recent years, although sources indicated that going forward it may be cut to around half that with about $200 million allocated to the U.S. 

Both PHD and Maxus are believed to be in the latest review; it was unclear if other shops were participating. But sources said the review is well under way and that a decision is expected later this month. 

SC Johnson brands include Pledge, Ziploc and Shout, among many others.

SC Johnson did not immediately respond to a request for comment on the review.
