Mandatory Sinking-Fund Redemption

A requirement to redeem a fixed portion of term bonds, which may comprise the entire issue, in accordance with a fixed schedule. Although the principal amount of the bonds to be redeemed is fixed, the specific bonds which will be called to satisfy the requirement as to amount are selected by the trustee on a lot basis.

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.
