Dynamic Asset Allocation for Stable Annuity Payments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current annuity payment systems face challenges in accurately determining payment amounts based on individual life expectancy, leading to potential overpayment or underpayment for annuitants, and lack dynamic asset allocation strategies to adapt to changing life stages and market conditions.
Innovation Solution
Implementing a dynamic asset allocation method that automatically reallocates assets over time based on demographic factors such as age, gender, and life expectancy, using a benchmark rate to determine annuity payments, which can adjust from income generation to income preservation as the annuitant ages, ensuring consistent payments throughout their lifetime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If annuity payments are based on fixed safe investments (money market funds and bonds), then payment stability is ensured, but return on investment is limited and may not meet income requirements for the annuitant's expected lifespan
Solution Approach 1:
The patent applies dynamic asset allocation by automatically adjusting the proportion of equities and fixed-income securities in the annuity investment portfolio over time. The system transitions from higher equity allocation (higher risk/return) in earlier years to higher fixed-income allocation (lower risk/stability) in later years, optimizing both return and stability across the annuitant's expected lifespan
Solution Approach 2:
The patent changes investment parameters (asset allocation percentages) based on time elapsed and annuitant characteristics. The system uses actuarial tables and investment performance data to dynamically adjust portfolio composition, transforming the static safe investment approach into a adaptive strategy that balances risk and return
2Productivity
If annuity payments are determined using estimated mortality dates, then the annuity provider can calculate payment amounts, but individuals living past their estimated mortality date receive more than they invested while those dying early pay for others
Solution Approach 1:
The patent implements feedback mechanisms by continuously monitoring actual annuitant survival patterns against actuarial estimates and adjusting future payment calculations accordingly. The system uses actual investment performance and mortality experience to refine payment determinations, ensuring fairness across the annuity pool
Solution Approach 2:
The patent performs preliminary actions by pre-calculating asset allocation strategies and payment schedules based on extensive actuarial analysis before annuity payments begin. The system establishes dynamic allocation parameters in advance that are designed to achieve both fairness and sustainability across the annuitant population
3Loss of energy
If annuities offer tax-deferred growth, then post-retirement annuitants benefit from lower tax brackets, but taxation at disbursement reduces the net payment amount
Solution Approach 1:
The patent optimizes tax parameters by adjusting asset allocation to maximize after-tax returns. The system considers tax-deferred growth characteristics and disbursement taxation rules when determining investment strategy, transforming fixed tax rules into a dynamic optimization problem

AI summary
An annuity is provided to an annuitant based on the performance of an investment. Assets of the investment are automatically reallocated over time and the annuity payment may change based on the performance of the automatically allocated assets. In some examples, the assets are automatically reallocated based on a demographic, which can include an age, a range of ages, and/or a gender.
