The number of executive search and leadership consulting consultants at December 31, 2010 was 347, compared to 359 at December 31, 2009, and 343 at September 30, 2010.

Consolidated salaries and employee benefits increased 19.1 percent to $82.7 million, from $69.4 million in the comparable quarter of 2009. The increase mostly reflects higher bonus accruals associated with the increase in net revenue, but also includes an increase in base compensation and payroll taxes associated with an 8.3 percent increase in employee headcount as well as the restoration in 2010 of certain salaries and employee benefits that were eliminated in 2009 as part of cost cutting initiatives. Salaries and employee benefits were 65.0 percent of net revenue for the quarter, compared to 63.2 percent in the 2009 fourth quarter.
