The fixed account is credited interest on a daily basis, similar to a traditional savings account.
Because of the nature of the index account, it credits interest a little differently. If money is moved to the index account, the policy will have a new segment created on the day of transfer. This segment lasts for one year from that date. The next month, a new segment is created. So a policy may have a segment for each calendar month in which money is allocated to the index account.
At the end of the one year period for the segment, the interest credited will be calculated based on the specifics of that segment.
At the end of a segment, the policyholder may 1) restart a new index account segment or 2) reallocate the segment’s maturing value to the fixed account.
