- Definition

Prepaid debt fees represent the capitalized direct costs incurred related to the issuance of debt. These costs are amortized to interest expense over the lives of the respective borrowings using the effective interest method. When debt is repaid early, or first becomes convertible the related portion of unamortized prepaid debt fees is written-off and included in interest expense.
