Celesio also maintains bilateral credit lines with a total committed and uncommitted balance of $1.8 billion. During the first nine months of 2015, Celesio borrowed and repaid $259 million and $196 million under these credit lines primarily relating to short‑term borrowings. As of December 31, 2014 and March 31, 2014, there were $225 million and $188 million outstanding under these credit lines. Accounts Receivable Sales Facility In November 2014, we extended our existing accounts receivable sales facility (the “Facility”) for a two-year period under terms substantially similar to those previously in place. The committed balance of the Facility is $1.35 billion, although from time to time, the available amount of the Facility may be less than $1.35 billion based on accounts receivable concentration limits and other eligibility requirements. The Facility will expire in November 2016 and we anticipate renewing the Facility before its expiration. During the first nine months of 2015, there were no borrowings under the Facility. During the first nine months of 2014, we borrowed and repaid $150 million of short-term borrowings under the Facility. At December 31, 2014 and March 31, 2014, there were no short‑term borrowings and related securitized accounts receivable outstanding under the Facility. The Facility contains requirements relating to the performance of the accounts receivable and covenants relating to the Company. If we do not comply with these covenants, our ability to use the Facility may be suspended and repayment of any outstanding balances under the Facility may be required.
