Auto-portability boosts 401(k) plan results in new EBRI research

The Employee Benefits Research Institute (EBRI) has added yet another study to a growing body of research supporting the substantial retirement savings public policy benefits of auto-portability.

EBRI Issue Brief no. 473, by research director Jack VanDerhei, Ph.D., compared the outcomes of participants in 401(k) defined contribution plans with auto-enrollment against defined benefit (DB) plans.

While the primary objective of EBRI’s research was to address a growing public policy concern over the relative decline of DB plans, this study also evaluated the significant, positive impact that auto-portability could have upon the retirement security of Americans who participate in 401(k) plans.

Comparing DB vs. DC plans with auto-enrollment

In the latest analysis, EBRI specifically examined the amount of retirement income that could be produced by auto-enrollment 401(k) plans and then determined the final-average DB accrual rate required to generate an equivalent retirement income.

Under a baseline set of assumptions, which included historical rates of return and annuity purchase prices reflecting average 1986-2013 bond rates, auto-enrollment 401(k) plans fared quite well against their DB counterparts.

In the baseline, EBRI found that few scenarios yielded results where the equivalent DB accrual rate was under 1.5%.  In other words, DB plans would typically have to accrue at more-generous rates to “break-even” with auto-enrollment 401(k) plans.

However, when EBRI applied various “stress tests” by reducing rates of return, or by utilizing current annuity prices, auto-enrollment 401(k) plans lost their comparative advantage to DB plans.

Auto-portability: The Great Equalizer

When EBRI’s equivalence comparisons incorporated auto-portability, which reduces plan leakage from cashouts, auto-enrollment 401(k) plans delivered substantially better results.

Pairing auto-enrollment 401(k) plans with auto-portability resulted in DB plans having to provide far more generous accrual rates to achieve equivalence vs. baseline.

The impact of auto-portability was particularly impressive among the lowest income quartile, “given their lower account balances and the negative correlation between account balances and cashout activity.”

Additionally, EBRI found auto-portability’s results to be “dramatic for males in the lowest income quartile with only 11-20 years of plan eligibility” requiring a 3.1% DB accrual rate to reach equivalency, an increase of 82% over the baseline accrual rate of 1.7%.

Extending the DB vs. DC plan comparisons to millennials

On 2/14/19, as a follow-on to its initial analysis, EBRI released an infographic – How Will Young Millennials Fare With Defined Contribution vs. Defined Benefit Plans? – revealing the beneficial effect of auto-portability on millennials.

When auto-portability was added to 401(k) plans, millennials — both male and female, for all years of eligibility, and for all income quartiles — experienced dramatic improvements in 401(k) plan performance vs. baseline, as measured by break-even DB plan accrual rates.

The growing body of research supporting auto-portability

This analysis adds to a growing body of research from EBRI demonstrating that auto-portability, by reducing cashout leakage, broadly increases retirement security and delivers significant benefits for America’s defined contribution system.
