Abstract
A method of simulating future cash flow for a given asset allocation under a variety of economic conditions, measuring the frequency of failure of the cash flow to avoid one or more predefined risks. Assigning user-selected weights to avoidance of specified risks and alternative user-selected weights to maximization of rate of return, the invention utilizes the cash flow simulation to produce a performance index. By methodological testing through asset allocation adjustments, the optimum performance index is determined, thereby identifying the optimum asset allocation.

Plan assets are projected into the future by starting with assets on hand, subtracting benefits as they are projected to be disbursed, adding projected employee and third-party contributions, introducing projected investment returns and such projected percentage of payroll employer contributions as are necessary to maintain financial soundness of the plan. Risk tolerance baselines include a user-selected multiple of benefits, a projected percentage of payroll employer contribution level at more (less) than the initial level by a user-designated margin, a user-designated percentage of user-defined liabilities, that diminished level of assets from which return to the initially assumed rate of investment return within a user-selected number of years has a lower user-designated probability of occurrence than acceptable to the user, and other comparable user-designated alternatives, Projected investment returns of individual asset classes are either the interaction of projected inflation deflators and real (net of inflation) asset class returns generated independently of each other or in tandem, with projections historically (or modified historically) or parametrically developed. Alternatively, projected nominal rates of return of individual asset classes are extracted from history by stringing together consecutive periods of user-selected length. Projected percentage of payroll employer contributions are dependent on feedback from the results of other simulated inflows and outflows, the overlay of computer-developed amortization over a user-selected amortization period of investment return gains and losses relative to an underlying user-selected baseline rate of return, such percentage of payroll employer contributions to reflect the requirement that employer contributions be the balancing item to maintain financial soundness of the plan. (d) repetitively performing step (c) for different asset allocations within the tolerable range until the asset allocation having the lowest weighted average measure of risk tolerance failure, or performance index, is determined. - View Dependent Claims (5, 6, 7)
