The Journal of Performance Measurement is pleased to bring you TSG's Third Biennial Performance Survey.  Conducted by TSG (TSG), a consulting firm and information provider to the money management industry, the surveys this year covered a fourth group of respondents: plan sponsors.  This is in addition to money management firms, investment consultants, and verification firms-each of which was surveyed separately.  Also new this year, TSG has taken on cosponsors: verification providers Deloitte & Touche LLP and Grant Thornton LLP, and performance software supplier First Rate, Inc.
