Edits from previous versions:

• Removed a few less relevant expert networks that previously made the list.

• Categorized all spend by consulting firms as "Consulting". In previous versions of this report, we left a third of it in the PE category. We made this change to reflect that it is the Consulting firms who decide which expert networks they spend the money with, even though they spend it on projects for a PE fund.
