CenterPoint Houston’s$300 million credit facility, which is scheduled to terminate September 9, 2019, can be drawn at the London Interbank Offered Rate plus 1.125% based on CenterPoint Houston’s current credit ratings. The revolving credit facility contains a financial covenant which limits CenterPoint Houston's consolidated debt (excluding transition and system restoration bonds) to an amount not to exceed 65% of its consolidated capitalization.

CenterPoint Houston was in compliance with all financial covenants as of March 31, 2015.

Other. As of both March 31, 2015 and December 31, 2014, CenterPoint Houston had issued $408 million of general mortgage bonds as collateral for long-term debt of CenterPoint Energy. These bonds are not reflected in the consolidated financial statements because of the contingent nature of the obligations. CenterPoint Energy held $290 million of its collateralized debt for future remarketing.
