The Company believes it is probable that the Company will not be in compliance with certain covenants under its credit facilities at measurement dates within the twelve months after March 31, 2013. If such a default occurs, the Company may also be in default under the Indenture for the 2010 Notes. A default would occur under the Indenture, following applicable notice and expiration of applicable cure periods, if the Company fails to pay indebtedness in excess of $50 million at final maturity (or when otherwise due) or if such indebtedness is accelerated. As such, the 2010 Notes were classified as a current liability in the condensed consolidated balance sheet beginning March 31, 2013 and remained classified as a current liability as of June 30, 2013.
