Debt Disclosure [Abstract]

Debt Outstanding

We had the following debt outstanding as of the dates shown below which are net of debt issuance costs (bank debt interest rate at December 31, 2015 is shown parenthetically) (in thousands). The expenses of issuing debt are capitalized and included as a reduction to debt in the accompanying consolidated balance sheets. These costs are amortized over the expected life of the related instruments. When debt is retired before maturity, or modifications significantly change the cash flows, the related unamortized costs are expensed. No interest was capitalized during 2015, 2014, and 2013.
