Debt Discounts or Premiums and Debt Issue Costs

Debt discounts or premiums and debt issue costs incurred in connection with the issuance of debt are capitalized and amortized to interest expense based on the related debt agreements primarily using the effective interest method. Unamortized discounts or premiums are written off and included in our gain or loss calculations to the extent we retire debt prior to its original maturity date. Unamortized debt issue costs are included in deferred charges and other assets in our Consolidated Balance Sheets.
