[1] Represents the weighted-average interest rate in effect at the respective periods for the revolving credit facility and term loan borrowings, including any applicable margin. The interest rates do not include amortization of debt issuance costs or commitment fees.

[2] 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 condensed 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 condensed consolidated balance sheet.
