Concentration of Revenue –

In the three month periods ended June 30, 2015 and 2014, the two largest customers represented in aggregate 40 percent and 43 percent of consolidated revenue. In the six month period ended June 30, 2015 and 2014, the two largest customers represented in aggregate 39 percent and 37 percent of consolidated revenue. However, they were not the same two customers in all periods. Most of our customers have multi-year contracts with recurring minimum revenue as well as professional services fees, that vary by period depending on their business needs.
