A loan in which the whole of the principal is repaid in a single final payment known as a 'bullet', although interest may be paid in interim payments. Compare with an amortizing loan.
A deferred interest bond is a type of bond that does not pay interest periodically like traditional bonds. Instead, it accrues interest, which is paid in a lump sum at maturity. An example of a deferred interest bond is a zero coupon bond.
