The index linked interest, if any, is based on the difference between the index value at the end of the term and the index value at the start of the term. Interest is added to your annuity at the end of the term.
Since interest cannot be calculated before the end of the term, use of this design may permit a higher participation rate than annuities using other designs.
Since interest is not credited until the end of the term, typically six or seven years, you may not be able to get the index-linked interest until the end of the term.
