Debt Issuance Costs
Debt Issuance Costs. The Company capitalizes legal fees, accounting fees, underwriting fees, printing costs, and other direct expenses associated with issuing debt. The costs associated with our Second Lien Notes are amortized on an effective interest basis over the term of the Second Lien Notes, while issuance costs related to our line of credit arrangement are capitalized and amortized ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings.
