aon exchange

Aon Hewitt offers a private insurance exchange to clients and claims that the 18 companies covering 600,000 people who are users are experiencing lower health care spending.  The firm says that health costs are projected to grow 3.5% in 2015 for these users, compared to industry-wide estimates of 6.5% to 8% increases.  But it appears that the "savings" are due largely to enrollees choosing less-rich benefit designs, which means they were paying more for their health care out-of-pocket.
