More than 200 school districts across California are taking a second look at the high price of the debt they've taken on using risky financial arrangements. Collectively, the districts have borrowed billions in loans that defer payments for years — leaving many districts owing far more than they borrowed.

In 2010, officials at the West Contra Costa School District, just east of San Francisco, were in a bind. The district needed $2.5 million to help secure a federally subsidized $25 million loan to build a badly needed elementary school.

Charles Ramsey, president of the school board, says he needed that $2.5 million upfront, but the district didn't have it.
