[1] As of January 1, 2016, we have adopted ASU 2015-03 and ASU 2015-15 with retrospective application. This resulted in a reclassification from other non-current assets to long-term debt, less current portion for debt issuance costs as of December 31, 2015. Refer to Note 2, “Recently Issued Accounting Standards” of the notes to the condensed consolidated financial statements for further details.
