Debt Service Requirements  

Amounts required to pay debt service, often expressed in the context of a time frame (such as ?annual debt service requirements?).

Remarks: Bond funds including mutual funds (open-end and closed-end, actively managed and indexed), exchange-traded funds and unit investment trusts offer a convenient and affordable way to invest in a diversified portfolio of bonds, but a bond fund investment can differ from a bond investment in ways that are important to understand.
