Our $1.2 billion senior credit facility maturing in June 2019, our $250.0 million term loan maturing in July 2015, our $175.0 million private placement notes maturing in October 2017, our $125.0 million private placement notes maturing in December 2019, our $225.0 million private placement notes maturing in October 2020, and our $125.0 million private placement notes maturing in December 2022, all require us to comply with various financial, reporting and other covenants and restrictions, including a restriction on dividend payments. The financial debt covenants are the same for the senior credit facility and the private placement notes. At June 30, 2015, we were in compliance with all of our financial debt covenants.

As of June 30, 2015 and December 31, 2014, we had $152.2 million and $162.9 million, respectively, committed to outstanding letters of credit under our senior credit facility. The unused portion of the revolving credit facility as of June 30, 2015 and December 31, 2014 was $685.2 million and $577.1 million, respectively.

Our $250.0 million term loan that matured on July 1, 2015 was classified as long-term debt and was refinanced by using our long-term senior credit facility.

We repaid our $100.0 million private placement notes that matured in April 2015 by borrowing from our long-term senior credit facility.

On April 30, 2015, we entered into a note purchase agreement with several institutional purchasers pursuant to which we have issued and sold to the purchasers $200.0 million of our new seven-year 2.72% unsecured senior notes (the "Series A notes") and $100.0 million of our new eight-year 2.79% unsecured senior notes (the "Series B notes"). Closing of the issuance and sale of the notes occurred on July 31, 2015.

The Series A notes bear interest at the fixed rate of 2.72% per annum, and the Series B notes bear interest at the fixed rate of 2.79% per annum. Interest will be payable in arrears semi-annually on January 31 and July 31, beginning on January 31, 2016. The principal of the Series A notes will be payable at the maturity of the notes on July 31, 2022, and the principal of the Series B notes will be payable at the maturity of the notes on July 31, 2023. The notes are unsecured obligations.
