"All [survey] respondents work in a plan sponsor role. The majority (91.7%) reported that they benchmark their defined contribution plans once per year, while the rest (8.3%) do so every five years. When the plan is benchmarked, 91.7% measure average participation rate, and the same percentage measure administrative expenses against those of peer plans. More than 83% measure average deferral percentages, and 100% consider their investment expenses compared with peer plans."
