See what 131 companies did for compensation consultants and 12 companies did for management comp consultants in 2017. Info includes firm used and fees, if disclosed.
Please note that the averages are not fully comparable by year since the list of companies changes annually. However, it is fair to think that compensation consultant fees are coming down slightly due to increase number of firms and more competitive pricing.
Management comp information is not comparable since companies have wide swings in what they disclose. The management comp information is purely FYI.
