Halley wasn’t the first to see the comet, of course – in fact, it had been recorded by Chinese astronomers as far back as 240 BC, noted subsequently in Babylonian records, and perhaps most famously shortly before the 1066 invasion of England by William the Conqueror (who claimed the comet’s appearance foretold his success). Halley noted appearances by the comet in 1531, 1607 and 1682, and based on those prior observations – and the application of the work and mathematical formulas of his friend Isaac Newton – predicted the return of the comet in 1758, which it did, albeit 16 years after his death in 1742.
Of course, the importance of repeated, measured observations isn’t restricted to celestial phenomena. Consider that individual retirement accounts (IRAs) currently represent about a quarter of the nation’s retirement assets; and yet, despite an ongoing focus on the accumulations in defined benefit (pension) and 401(k) plans that have, via rollovers, fueled a significant amount of this growth, a detailed understanding as to how these funds are actually used during retirement has, to date, not been as well understood.
To address this knowledge shortfall, the Employee Benefit Research Institute has developed the EBRI IRA Database, which includes a wealth of data on IRAs including withdrawals or distributions, both by calendar year and longitudinally, which provides a unique ability to analyze a large cross-sectional segment of this vital retirement savings component, both at a point in time and as the individual ages and either changes jobs or retires. Indeed, as a recent EBRI publication notes, the rate of withdrawals from these IRAs is important in determining the likelihood of having sufficient funds for the duration of an individual’s life, certainly where these balances are a primary source of post-retirement income.
Previous EBRI reports[i] have explored this activity for particular points in time, but a recent EBRI analysis[ii] looked for trends in the withdrawal patterns of a longitudinal three-year sample of individual post-retirement withdrawal activity, specifically those age 70 or older (in 2010), the point at which individuals are required by law to begin withdrawing money from their IRAS.
The EBRI analysis concluded that, when looking at the withdrawal rates for those ages 70 or older, the median of the average withdrawal rates over a three-year period indicated that most individuals are withdrawing at a rate that not only approximates what they are required by law to withdraw, but at a rate that is likely to be able to sustain some level of post-retirement income from IRAs as the individual continues to age.
Furthermore, the report notes that an examination of these trends over this period suggests that, based on the resulting distribution of average withdrawal rates over time as a function of the initial-year withdrawal rate, the initial withdrawal rate for those in this age group appeared to be one that these individuals are likely to continue to make the next year.
Of course, while the median withdrawal rates suggest many individuals would be able to maintain the IRA as an ongoing source of income throughout retirement, further study is needed to see if these individuals are maintaining those withdrawal rates over longer periods of time. Moreover, the integration of IRA data with data from employment-based defined contribution retirement accounts currently underway as part of initiatives associated with EBRI’s Center for Research on Retirement Income (CRI) will allow for an even more comprehensive picture of what those who may have multiple types of retirement accounts do as they age through retirement.
And we won’t have to wait 75 years to see how it turns out.
