Commercial Paper Program

As of March 31, 2014, we had approximately $290.3 million of commercial paper outstanding. The weighted average interest rate on borrowings at March 31, 2014 was 0.33%. Our commercial paper borrowings are classified as long-term debt because the borrowings are fully supported by availability under our revolving credit facility, which matures as currently structured in November 2017, more than one year from now.

Revolving Credit Facility

As of March 31, 2014, we had approximately $117.5 million of borrowings outstanding. The weighted average interest rate on borrowings at March 31, 2014 was 1.46%. The revolving credit facility contains various covenants and restrictive provisions that limit our ability to incur additional indebtedness, make investments or loans and create liens and require us to maintain a net funded indebtedness to total capitalization ratio, as defined in each agreement. We were in compliance with all covenants under the agreement at March 31, 2014. If we fail to perform our obligations under the covenants, the revolving credit commitment could be terminated, and any outstanding borrowings under the facility could be declared immediately due and payable.
