From a The New York Times' article "How Big a Payday for the Pay Consultants?":

Compensation consultant biases can arise when a company’s board uses the same consulting firm for pay design as well as other services such as human resources management and outsourcing advice. Because the fees earned by consultants for compensation work are far less than what they make on other business, there is a risk that compensation gurus will put together cushy pay packages in order to snare more lucrative gigs elsewhere in the corporate empire.

Here’s an easy fix: Require companies to detail in proxy statements all fees paid to consultants they hire, for compensation design and all other services.

When the Securities and Exchange Commission rewrote the laws on executive compensation disclosure last year, it didn’t require public companies to detail consultants’ fees. This was a mystifying mistake.
