Our $1.2 billion senior credit facility maturing in June 2019, our $100.0 million private placement notes maturing April 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, 2014, we were in compliance with all of our financial debt covenants.

On June 3, 2014, we and certain of our subsidiaries entered into a second amended and restated credit agreement (the “new credit agreement”) with Bank of America, N.A., as administrative agent, swingline lender, a lender and a letter of credit issuer, other lenders party to the new credit agreement, JPMorgan Chase Bank, N.A. and HSBC Bank USA, National Association, as syndication agents, and Union Bank, N.A. and Santander Bank, National Association, as co-documentation agents. The new credit agreement amended and restated our prior amended and restated credit agreement dated as of September 21, 2011. The new credit agreement increases our unsecured revolving credit facility from $1.0 billion to $1.2 billion and extends the maturity date of our borrowings from September 21, 2016 to June 3, 2019. We paid $2.1 million in financing fees which will be amortized to interest expense over the life of the new credit agreement.

As of June 30, 2014 and December 31, 2013 we had $212.2 million and $155.0 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, 2014 and December 31, 2013 was $511.5 million and $572.6 million, respectively.

Our $100.0 million private placement notes that mature in April 2015 were classified as long-term debt due to our intent to pay this obligation by borrowing on our $1.2 billion senior credit facility.

Guarantees

Shiraishi-Sogyo Co. Ltd. (“Shiraishi”) is an unrelated party in Japan that is expanding its medical waste management business. We have guaranteed Shiriashi’s loan of $4.7 million borrowed from JPMorganChase Bank N.A. which is currently due on December 31, 2014. Based on information currently available, we have concluded the guarantee is not probable of being called and, therefore, we have not recorded any contingent liability relating to this guarantee. We have also extended non-interest bearing loans to Shiraishi for approximately $15.7 million due April 18, 2018, which are reflected in the Condensed Consolidated Balance Sheet as part of long term "Other assets" at June 30, 2014 and December 31, 2013. There is a collateral agreement in place on the assets of Shiraishi and related companies in support of amounts owed to the Company.
