The building blocks of every bond and loan: who issues it, when it matures, how much principal is repaid, how interest is paid (fixed, floating or zero), where it ranks and what options it carries; how those features turn into cash flows and simple yield measures; and what the indenture says about sources of repayment, collateral and the affirmative and negative covenants that protect lenders.
How a bond's principal can be repaid (bullet, fully or partially amortizing, sinking fund, waterfall), how its coupon can be set (fixed, floating, step-up, credit-linked, PIK, index-linked, zero and deferred), which embedded options help the issuer or the investor (call, put, conversion, CoCo), and how the place of issue and tax rules change a bond's legal and after-tax profile.

How bond markets are carved up by issuer type, credit quality and maturity, which issuers borrow and which investors lend in each segment, how fixed-income indexes differ from equity indexes, and how new bonds are sold in the primary market and traded afterwards in a mostly over-the-counter secondary market, compared at each step with equities.
How companies and banks raise short-term money (credit lines, secured loans, commercial paper, deposits, interbank loans and repos), how a repurchase agreement works and what can go wrong with it, and why long-term borrowing looks so different for investment-grade and high-yield issuers.
