Most 401(k) plans today offer a low risk investment option designed to maintain a constant net asset value. This option is usually a money market or stable value fund.
Recently, the Securities Exchange Commission (SEC) made changes to the rules that govern money market mutual funds (MMFs). These changes are intended to increase MMF transparency as well as give investors additional protection during periods of extraordinary market stress, when redemptions in some MMFs can increase significantly. These changes are effective October 14, 2016.
The SEC changes affect 401(k) plans. If you are a 401(k) fiduciary, you should be evaluating any plan MMF today so it can be replaced (if necessary) prior to the deadline.
In the days following the 2008 Lehman Brothers bankruptcy, the Reserve Primary Fund, a $62 billion MMF, lowered its share price below $1 (“breaking the buck”) due to its holding in Lehman Brother debt. The SEC believed these events triggered a heavy sell-off of MMFs that invested in commercial paper and a breakdown in the commercial paper market in general, resulting in a cash squeeze for many businesses that affected the wider economy.
As a result of these events, the SEC decided new rules were necessary to reduce the risk of investor “runs” on MMFs in times of financial stress.
Summary of new rules:
Government | Prime (Retail) | Prime (Institutional) | |
NAV | Stable ($1) | Stable ($1) | Floating |
Eligibility | All investors | Natural persons only | All investors |
Fees and Gates | No | Yes | Yes |
While 401(k) plans are not required to comply with the SEC’s new MMF rules until October 14, 2016, 401(k) fiduciaries should be evaluating any plan MMF today so it can be replaced (if necessary) prior to the deadline.
Fiduciary considerations:
Ultimately, the best MMF choice for a particular 401(k) plan is a risk/reward decision for fiduciaries. Very risk averse fiduciaries are the most likely to choose a government MMF, while fiduciaries that see little potential for fees and gates are likely to choose a prime MMF to achieve higher yields. Like any fiduciary decision, either choice should be justified.
