The senior credit facilities include long-term, multi-currency committed revolving credit facilities that provide the company with up to the U.S. dollar equivalent of $1.5 billion. At September 30, 2017, taking into account outstanding letters of credit, approximately $1.2 billion was available under existing long-term, revolving credit facilities. In addition to these facilities, the company had approximately $936 million of short-term uncommitted credit facilities available at September 30, 2017, of which $374 million was outstanding and due on demand. At December 31, 2016, the company had $143 million outstanding under short-term uncommitted credit facilities.

The fair value of long-term debt was estimated to be $7.5 billion at September 30, 2017, and $7.7 billion at December 31, 2016. The fair value reflects the market rates at each period end for debt with credit ratings similar to the company’s ratings and is classified as Level 2 within the fair value hierarchy. Rates currently available to the company for loans with similar terms and maturities are used to estimate the fair value of long-term debt based on discounted cash flows.

Ball provides letters of credit in the ordinary course of business to secure liabilities recorded in connection with certain self-insurance arrangements. Letters of credit outstanding were $34 million at September 30, 2017, and $32 million at December 31, 2016.
