In June, the Washington-based think tank published a paper proposing a way that companies could automatically enroll a portion of retiring employees’ 401(k) assets into a lifetime income option that would provide them with monthly payments.

Under the plan, a portion of a retiring employee’s 401(k) assets would automatically be swept into an annuity product chosen by the employer unless employees opt out of the program. Retirees not opting out would stay in the plan for a trial two-year period, during which they would receive monthly payments from their 401(k) plan, according to the paper. After two years, retirees could choose to continue with the plan or cash out.

The goal is to make sure retirees’ savings last them through retirement, says Lina Walker, research director of the Retirement Security Project, a joint venture between the Brookings Institution and Georgetown University.

Too often, employees cash out their 401(k)s when they retire, she says. And while it might not be a big issue now since many retiring employees have both defined-benefit and defined-contribution plans, that won’t be the case in a few years, Walker says.

“Most people retiring now have both a 401(k) and a defined-benefit plan, so the whole issue of improving the payout options within a 401(k) hasn’t been a big deal,” Walker says. “But that’s not going to be the case 20 years from now.”

By having a two-year trial period for retirees to receive monthly payments, the plan could help change the mind-set of many retiring employees who are hesitant to keep their money in an annuity product, she says.

“We know that a lot of people undervalue lifetime annuity products because they don’t understand how they work and often the pricing isn’t transparent,” Walker says. “This could make it easier for them.”

Industry experts applaud the proposal for highlighting how 401(k) plans could better address the income needs of retirees.

“Everyone is always talking about how it’s too bad that employees always take lump sums out of their 401(k) plans, but no one is doing anything about it,” says Judith Mazo, senior vice president and director of research at Segal. “This is a practical way to address the situation.”

However, Mazo and other industry experts say it’s going to take a lot for employers to want to add annuities to their 401(k) plans because of fiduciary concerns as well as the administrative burden.

“Employers have not shown any sign of wanting to default employees into an annuity,” says Dallas Salisbury, president of the Employee Benefit Research Institute.

Salisbury also says it’s going to be difficult for insurance companies to price an annuity product if the account holders can cash out after two years. Usually the pricing of annuities is based on the life expectancy of the account holders.

“It appears to me this isn’t feasible,” he says.

But executives at MetLife, which offers annuities to 401(k) plans, say they could price the two-year trial product.

“MetLife would view pricing the trial annuitization feature of providing liquidity at the end of two years as being comparable to providing a death benefit equal to the value of the annuity during that two-year period,” says Jody Strakosch, national director, institutional income annuities. “This is a minor cost and is easily incorporated into the price of the annuity.”

However the issue of employers being willing to offer this program is going to be a weighty challenge for the proposal, says Melissa Kahn, vice president of government and industry relations at MetLife.

While the paper proposes safe harbors for employers, there’s a need for added incentives, she says.

Walker concedes that there are issues to be worked out. But she hopes the paper will initiate some conversation.

“We don’t have all of the answers,” she says. “But the basic concept is there.”
