( 3 ) includes our revolving credit facilities , our receivables securitization facility , and letters of credit . we assess our liquidity in terms of our ability to fund our operations and provide for expansion through both internal development and acquisitions . our primary sources of liquidity are cash flows from operations and our credit facilities . we utilize our cash flows from operations to fund working capital and capital expenditures , with the excess amounts going towards funding acquisitions or paying down outstanding debt . as we have pursued acquisitions as part of our growth strategy , our cash flows from operations have not always been sufficient to cover our investing activities . to fund our acquisitions , we have accessed various forms of debt financing , including revolving credit facilities , senior notes , and a receivables securitization facility . as of december 31 , 2016 , we had debt outstanding and additional available sources of financing , as follows : 2022 senior secured credit facilities maturing in january 2021 , composed of term loans totaling $ 750 million ( $ 732.7 million outstanding at december 31 , 2016 ) and $ 2.45 billion in revolving credit ( $ 1.36 billion outstanding at december 31 , 2016 ) , bearing interest at variable rates ( although a portion of this debt is hedged through interest rate swap contracts ) reduced by $ 72.7 million of amounts outstanding under letters of credit 2022 senior notes totaling $ 600 million , maturing in may 2023 and bearing interest at a 4.75% ( 4.75 % ) fixed rate 2022 euro notes totaling $ 526 million ( 20ac500 million ) , maturing in april 2024 and bearing interest at a 3.875% ( 3.875 % ) fixed rate 2022 receivables securitization facility with availability up to $ 100 million ( $ 100 million outstanding as of december 31 , 2016 ) , maturing in november 2019 and bearing interest at variable commercial paper from time to time , we may undertake financing transactions to increase our available liquidity , such as our january 2016 amendment to our senior secured credit facilities , the issuance of 20ac500 million of euro notes in april 2016 , and the november 2016 amendment to our receivables securitization facility . the rhiag acquisition was the catalyst for the april issuance of 20ac500 million of euro notes . given that rhiag is a long term asset , we considered alternative financing options and decided to fund a portion of this acquisition through the issuance of long term notes . additionally , the interest rates on rhiag's acquired debt ranged between 6.45% ( 6.45 % ) and 7.25% ( 7.25 % ) . with the issuance of the 20ac500 million of senior notes at a rate of 3.875% ( 3.875 % ) , we were able to replace rhiag's borrowings with long term financing at favorable rates . this refinancing also provides financial flexibility to execute our long-term growth strategy by freeing up availability under our revolver . if we see an attractive acquisition opportunity , we have the ability to use our revolver to move quickly and have certainty of funding . as of december 31 , 2016 , we had approximately $ 1.02 billion available under our credit facilities . combined with approximately $ 227.4 million of cash and equivalents at december 31 , 2016 , we had approximately $ 1.25 billion in available liquidity , a decrease of $ 178.5 million from our available liquidity as of december 31 , 2015 . we expect to use the proceeds from the sale of pgw's glass manufacturing business to pay down borrowings under our revolving credit facilities , which would increase our available liquidity by approximately $ 310 million when the transaction closes. .
