Same unit revenue was $3.6 million, down 2.1 percent from a year earlier. The company said same-unit revenue fell because of a 5 percent decrease in aggregate hours charged to clients during the September quarter, partially offset by a 1 percent increase in effective yield. CBIZ also cited what it called lower performance in several local business units. Same unit financial services revenue was $87 million, a decrease of 2.3 percent from just over $89 million a year earlier. The segment's results were buoyed by $5.5 million in revenue from acquired businesses.
