Transition to Old Age (Superannuation) in a 3-D, Age Based, Dynamic, Serially Connected and Annually Recalculated Retirement Distribution Model

Past research on the topic of sustainable withdrawal rates has primarily focused on longer distribution periods which apply to younger age retirees.A structural problem with pensions, annuities, and first generation "safe withdrawal rate" is a disconnect of benefits paid (fixed or fixed with COLAs) from the underlying asset values required to support those promised benefits. Underlying asset values are variable and may decrease in value, temporarily or permanently, due to market or economic forces. A sustainable methodology needs to keep benefits connected to supporting asset values year by year throughout the entire distribution period.This research project seeks to answer the following questions regarding superannuation (continuing to survive and live into very old ages):- What does the withdrawal rate profile need to look like for a retiree who survives into extreme old age (superannuation)?- What should the withdrawal rate sequence be in order to sustain portfolio values sufficient to continue cash flows from old retirement ages throughout superannuation?Sequence Risks, Distribution Periods (Longevity Percentiles), Asset Allocations and Superannuation represent the factors incorporated into four “levers” available to practitioners to measure and manage sustainable distributions from the earlier retirement years through superannuated retirement ages.High cash flows during early retirement years deplete the portfolio values such that cash flows are reduced during later retirement years. How does a practitioner measure this effect so as to manage cash flows both for the present and future?Dynamic, serially connected, and annually recalculated, cash flows based on age and longevity percentiles provide insights into retirement distribution tradeoffs
