Debt instrument, event of default description As of December 31, 2016 and 2015, we were in compliance with all of our financial covenants under our Indenture. As of the date of the filing of our annual report on Form 10-K, we are in default of the covenant to repay the Notes at their maturity (which constitutes an event of default of the Indenture as we describe elsewhere), and we are in default of the security agreement covenant relating to deposit account control agreements and the related Indenture covenant regarding compliance with the security agreement due to the Company initiated transfer of cash balances from controlled accounts to non-controlled accounts. In addition, one of our subsidiaries had not become a guarantor when formed in 2013 as required by the Future Guarantor covenant of the Indenture and therefore we were in default of the indenture from the formation of the subsidiary until we subsequently submitted documentation to the Trustee to have the subsidiary become an additional guarantor in April 2017. The Notes will continue to earn interest after the maturity date.
