Additional report context:
the changes in the capital structure between periods were mainly attributable to changes in outstanding commercial paper balances . debt covenants our debt agreements contain financial and non-financial covenants . to the extent that we are not in compliance with these covenants such an event may create an event of default under the debt agreement and we or our subsidiaries may be restricted in our ability to pay dividends , issue new debt or access our revolving credit facility . for two of our smaller operating companies , we have informed our counterparties that we will provide only unaudited financial information at the subsidiary level , which resulted in technical non-compliance with certain of their reporting requirements under debt agreements with respect to $ 8 million of outstanding debt . we do not believe this event will materially impact us . our long-term debt indentures contain a number of covenants that , among other things , limit the company from issuing debt secured by the company 2019s assets , subject to certain exceptions . our failure to comply with any of these covenants could accelerate repayment obligations . certain long-term notes and the revolving credit facility require us to maintain a ratio of consolidated debt to consolidated capitalization ( as defined in the relevant documents ) of not more than 0.70 to 1.00 . on december 31 , 2015 , our ratio was 0.56 to 1.00 and therefore we were in compliance with the covenant. .
