Current maturities of debt at June 30, 2014 primarily comprise our capital leases and amounts due under our term loan. Our consolidated debt had a weighted average interest rate of 5.11% and 5.25% at June 30, 2014 and December 31, 2013, respectively. Approximately 72% and 76% of our total debt had a fixed interest rate at June 30, 2014 and December 31, 2013, respectively.
Bank Credit Agreement
The Company has a $500 million bank credit facility due July 2018 with a syndicate of banks, including a sublimit of $175 million for letters of credit.
As of June 30, 2014, we have $235.0 million outstanding borrowings under our bank credit facility and have issued $31.6 million of letters of credit. The bank credit facility provides us with flexibility for working capital, if needed, and is guaranteed by a majority of our domestic subsidiaries. The subsidiary guaranty is a guaranty of payment of the outstanding amount of the total lending commitment, including letters of credit. The bank credit facility contains certain financial covenants, including a minimum interest coverage ratio, a maximum leverage ratio, and certain dividend and share repurchase restrictions. We pay a quarterly fee on the unused commitment, which was 0.35% at June 30, 2014. As of June 30, 2014, we have $233.4 million in borrowing capacity under the bank credit facility.
Debt Issuances and Additions
In May 2014, we issued $550.0 million of unsecured 5.375% Senior Notes due May 2024. We used the net proceeds from this offering, along with a $95.0 million draw on our Bank Credit Facility, to repay our 6.75% Senior Notes due April 2015, 6.5% Senior Notes due April 2019, and 7.0% Senior Notes due May 2019 along with associated refinancing costs. The newly issued notes are subject to the provisions of the Company's Senior Indenture dated as of February 1, 1993, as amended, which includes covenants limiting, among other things, the creation of liens securing indebtedness and sale-leaseback transactions.

Debt Extinguishments and Reductions
During the first half of 2014, we made debt payments of $898.2 million for scheduled and early extinguishment payments as follows:
$250.0 million in aggregate principal of our 7.0% Senior Notes due May 2019;
$200.0 million in aggregate principal and $9.1 million in unamortized premiums of our 6.5% Senior Notes due April 2019;
$136.5 million in aggregate principal of our 6.75% Senior Notes due April 2015;
$135.0 million in aggregate principal of our Term Loan due July 2018;
$86.4 million in aggregate principal and $21.7 million in unamortized premiums of our 3.125% Senior Convertible Notes due 2014;
$45.0 million in aggregate principal and $14.2 million in unamortized premiums of our 3.375% Senior Convertible Notes due 2016; and
$0.3 million in other debt.
Subsequent to June 30, 2014, we made an additional debt payment of $13.0 million on our Term Loan due July 2018.
Certain of the above transactions resulted in the recognition of a loss of $29.2 million recorded in (Losses) gains on early extinguishment of debt in our unaudited condensed consolidated statement of operations.
During the first half of 2013, we paid an aggregate of $5.2 million to repay $4.8 million of 7.875% Debentures due February 2013 and $0.4 million to retire other debt resulting in the recognition of a gain of $0.5 million recorded in Losses (gains) on early extinguishment of debt in our unaudited condensed consolidated statement of operations.
Capital Leases
During the six months ended June 30, 2014 and 2013, we acquired $19.0 million and $28.5 million, respectively, of capital leases, primarily related to transportation equipment. We retired $14.5 million and $13.0 million of capital lease obligations for the six months ended June 30, 2014 and 2013, respectively.
