On April 5, 2012, subsequent to quarter end, collateral that was being held on a large commercial surety account was accelerated, resulting in a $50.0 million cash outflow. Though the original collateral repayment schedule required the return of $16.7 million in the second quarter of 2012, terms of the renegotiated agreement included substitution of a portion of the collateral with $25.0 million in irrevocable letters of credit and the return of the $50.0 million in cash.  This return will be reflected as a reduction to operating cash flow in the second quarter of 2012.
