I have no concerns of that nature at all. In fact, when students look like they're going to be in default, there have been a number of programs put in place to help them better manage that debt to ultimately repay--both to prolong it, but also recent programs have helped lower the interest rate for those who are in need. The debt write-off comes when there is actual default. So first there's potential default, programs that assist the students, then there may be an actual default. There are a number of mechanisms to try to recover through other sources prior to it being written off. So no.
