[1] The December 31, 2014 balances have been adjusted to reflect unamortized deferred loan costs attributable to term loans as a reduction of the related debt balances whereas they were previously included in other current assets and other non-current assets. This change in presentation was the result of the early adoption of ASU 2015-03. The December 31, 2014 balances for long-term debt and the current portion of long-term debt are now reflected net of $2.5 million and $0.8 million of unamortized deferred loan costs, respectively.
