How are stable value funds structured?
Stable value funds are structured in two ways: as a separately managed account, which is a stable value fund managed for one specific 401(k) plan; or as a commingled fund, which pools together assets from many 401(k) plans. Commingled funds offer the benefits of diversification and economies of scale for smaller plans. Regardless of how stable value funds are structured, they are comprised of a diversified portfolio of fixed income securities that are insulated from interest rate movements by contracts from banks and insurance companies. The protection from interest rate volatility is universal to stable value funds. How this contract protection is delivered depends on the type of stable value fund investment purchased.
