Restricted cash
During 2017, we placed deposits in debt service reserve accounts under the terms and conditions set forth under our 2017 Credit Facility. Additionally, as part of the acquisition of NPTI and the assumption of NPTI's indebtedness (as further described in Note 13), we are required to maintain debt service reserve accounts under certain of NPTI's secured credit facilities and sale leaseback arrangements. Funds held in these accounts will be released upon the maturity of such facilities and have accordingly been accounted for as non-current restricted cash on our consolidated balance sheet.
