NOTE 11. DEBT

As of September 30, 2018 and December 31, 2017, our long-term debt included borrowings outstanding under our $1,050.0 million variable rate credit facility, which is comprised of a $200.0 million revolving credit facility (with a $150.0 million sublimit for letters of credit), a $600.0 million Term Loan A and a $250.0 million Term Loan B. As of September 30, 2018 and December 31, 2017, there were no borrowings outstanding on our revolving credit facility. As of September 30, 2018 and December 31, 2017, our outstanding long-term debt included a $35.0 million variable rate, tax-exempt industrial development bond that financed the construction of a U.S. plant in prior years. We also have a $25.0 million letter of credit facility, also known as our bi-lateral facility.

We utilize lines of credit and other commercial commitments in order to ensure that adequate funds are available to meet operating requirements. Letters of credit are currently arranged through our revolving credit facility, our bi-lateral facility and our securitization facility. Letters of credit are issued to third party suppliers, insurance institutions and financial institutions and typically can only be drawn upon in the event of AWI’s failure to pay its obligations to the beneficiary. The following table presents details related to our letters of credit:
