Chapter 9: Southwest Airlines: Analysis of Debt and Liabilities

Understanding this relationship between coupon rates and market conditions is essential for determining a company's actual cost of borrowing. The chapter then addresses the accounting treatment of bond discounts and premiums through two primary amortization approaches: the straight-line method, which allocates equal periodic adjustments to interest expense, and the effective-interest method, which produces varying periodic adjustments based on the bond's carrying value. These methods affect both the reported interest expense and the carrying value appearing on the balance sheet throughout the bond's life. The chapter categorizes bonds by their structural characteristics, including term bonds and serial bonds distinguished by their maturity patterns, secured bonds backed by specific assets versus unsecured debentures, callable bonds that issuers may redeem before maturity, and convertible bonds that investors may exchange for equity securities. Beyond traditional bonds, the chapter explores additional liability categories including deferred income tax obligations and lease arrangements. The treatment of leases represents a particularly important distinction, as finance leases require balance sheet recognition while operating leases under older standards appeared only in footnote disclosures. To evaluate financial health and solvency, the chapter introduces critical analytical ratios including the debt ratio measuring total liabilities relative to total assets, the leverage ratio or equity multiplier comparing average total assets to average stockholder equity, and the times-interest-earned ratio assessing the adequacy of operating income to cover interest obligations. These metrics enable stakeholders to evaluate how effectively a company manages its debt obligations and financial risk. The chapter concludes by examining financial statement presentation standards, including balance sheet classification of long-term liabilities, the detailed note disclosures required under accounting standards, and the cash flow implications within the financing activities section of the statement of cash flows.
