  • ANNUITIES APPARATUS AND ASSOCIATED METHODS
    Publication number: 20120095937
    Abstract: There are described methods for determining a user bonus payment amount, which may be associated with an annuity fund. Such a user bonus payment amount can be accumulated with a user basic payment amount to provide a user annuity payment associated with the annuity fund. In some examples, this is achieved by determining a performance parameter from fund data associated with the performance of an annuity fund, and comparing the determined performance parameter with a user-threshold parameter, where user bonus payment amount is based on the comparison of the performance parameter and the user-threshold parameter. There is also described associated apparatus comprising a comparator configured to receive fund data and an accumulator configured to determine a user bonus payment amount.
