(a)	As of June 30, 2016, the actual availability under the accounts receivable sales facility fell below the facility borrowing capacity to $1.2 billion primarily due to a decrease in eligible trade receivables as a result of the current market price environment for the finished products that we produce.


(b)	In July 2016, we amended one of our committed letter of credit facilities to extend the maturity date from June 2016 to June 2017.
