As of March 31, 2013, we have $86.6 million outstanding under our Bank credit facility and $31.7 million of letters of credit.

We pay a quarterly fee on the unused commitment, which was 0.35% for the first quarter. As of March 31, 2013, we have $381.7 million in borrowing capacity under the bank credit facility.
