In the wake of news about a spike in new applications for unemployment benefits comes another potentially troubling sign: A record number of workers made hardship withdrawals from their retirement accounts in the second quarter.

What’s more, the number of workers borrowing from their accounts reached a 10-year high, according to a report issued yesterday by Fidelity Investments.

The trends reflect the financial stress many workers find themselves in as the economy struggles to find sure footing, said Beth McHugh, Fidelity’s vice president of marketing insight.

High unemployment and companies cutting back on overtime or overall hours have reduced the take-home pay of many workers.

"People tend to be taking home less," she said. "As a result, the percentage of individuals initiating hardship distributions is one of the things we’re concerned about."

Fidelity administers 17,000 plans, which represents 11 million participants. In the second quarter, some 62,000 workers initiated a hardship withdrawal. That’s compared with 45,000 in the same period a year ago.

What’s also eye-opening is that 45 percent of participants who took a hardship withdrawal a year ago took another one this year, McHugh said.

To be eligible for a 401(k) hardship withdrawal, individuals must demonstrate an immediate and heavy financial need, according to IRS regulations. Certain medical expenses; costs relating to the purchase of a primary home; tuition and education expenses; payments to prevent eviction or foreclosure on a primary home; burial or funeral expenses; and repair of damage to a primary home meet the IRS definition and are permitted by most 401(k) plans.

A key concern is that these withdrawals are just that; they are not loans. As a result, there can be a significant impact on someone’s overall retirement savings. If the worker is younger than 59 1/2 , he or she will pay a 10 percent penalty for early withdrawal in addition to taxes.
