Notes are written promises issued by a company or government to borrow money for a defined period, typically paying interest and returning the principal at maturity; they are essentially formal IOUs used to raise short- to medium-term funding. For investors, notes matter because they provide a predictable stream of income and carry credit and timing risk—like lending cash to someone with a set payback date—so their yield, repayment terms and issuer strength determine potential return and safety.
