New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	During 2015 we early adopted FASB Accounting Standards Update No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires certain debt issuance costs to be presented in the Consolidated Balance Sheets as a direct deduction from the carrying value of the associated debt liability. The Company applied the provisions of this standard and prior year balances have been reclassfied to reflect the current year presentation. The impact to the Consolidated Balance Sheets at December 31, 2015 and December 31, 2014 was to decrease Other Assets and Long-Term Debt by $4,539 and $5,909, respectively.
