"With tuition increases outpacing investment returns, the state is considering a variety of options, including suspending a program through which parents buy future college tuition credits in today's dollars," The Tennessean reports. "State Treasurer David Lillard Jr. could recommend suspending new enrollment in the prepaid tuition plan, among the possibilities, depending on findings from an analysis of assets and liabilities later this year, said Blake Fontenay, his spokesman. A snapshot taken a year ago found a $12.7 million deficit, although the state's treasury department, which administers the program, said there was enough money to cover at least a decade's worth of tuition expenses. Keeping enrollment open would bring in more funds to help with short-term obligations, but would also increase long-term liabilities, officials said."
