As of December 31, 2017, the unused borrowing capacity under our $9.0 billion credit facility was approximately $8.9 billion. The credit facility does not require us to comply with financial covenants or maintain specified credit ratings, and it permits us to borrow even if our business has incurred a material adverse change. We use the credit facility for the issuance of letters of credit and for general corporate purposes. In March 2016, we entered into a credit facility insured by Eksportkreditnamnden Stockholm, Sweden (EKN), the Swedish export credit agency. As of December 31, 2017, we had an outstanding balance of $0.8 billion. We used this credit facility to finance network equipment-related purchases. In July 2017, we entered into credit facilities insured by various export credit agencies with the ability to borrow up to $4.0 billion to finance equipment-related purchases. The facilities have borrowings available, portions of which extend through October 2019, contingent upon the amount of eligible equipment-related purchases made by Verizon. At December 31, 2017, we had not drawn on these facilities. In January 2018, we drew down $0.5 billion. 2017 Annual Report | Verizon Communications Inc. and Subsidiaries 69
