[1] In accordance with ASU 2015-03, unamortized debt issuance costs are reflected as a direct deduction from the carrying amount of the related debt. The Company applied the new guidance retrospectively to all prior periods presented in the consolidated financial statements. As a result, $1.6 million of unamortized debt issuance costs were reclassified from other investments and assets to a reduction in long-term debt on the December 31, 2015 consolidated balance sheet.
