The bond is the legal relationship between at least two persons, by virtue of which one (the debtor) is obliged to perform or make performance to another person (the creditor). In the Securities Act, the bond is usually a fixed-interest partial debenture, i.e. a security of a larger, usually long-term debt (bonds), with a round amount.
German: Obligation (575)
