Debt

We classify our debt based on the contractual maturity dates of the underlying debt instruments. We defer costs associated with debt issuance over the applicable term. These costs are then amortized as interest expense in our Consolidated Statements of Income and Comprehensive Income. The following table summarizes the net carrying value of our outstanding debt (in millions):
