Ten Questions Every Fiduciary Should Ask About Their Default Investment
Introduction: When Defaults Become Decisions
Default investment solutions within most defined contribution plans are no longer merely placeholders. The investment selection that plan sponsors make on behalf of their participants is, whether by design or by inertia, the portfolio the majority will hold for much of their working lives.
Participant inertia and tools such as automatic enrollment can be powerful mechanisms for placing employees on a path toward retirement security. The trade-off, however, is that the default investment necessarily becomes the most consequential investment decision made within the plan.
The widespread adoption of Qualified Default Investment Alternatives (QDIAs) and the outsized role they now play in shaping participant outcomes has reframed the role of plan fiduciaries. The core question is no longer simply whether a plan has selected a Target-Date Fund (TDF) default that complies with ERISA’s QDIA rules. It is whether the committee has established a governance process capable of overseeing a complex investment structure that now functions as the de facto retirement portfolio for most participants.
Litigation, regulatory guidance, and industry practice increasingly reflect this evolution. Attention has moved from selection to stewardship — from choosing a fund to governing a system. This shift does not imply that fiduciaries are expected to predict markets or guarantee outcomes. Rather, it calls for defining objectives for the plan, understanding the embedded assumptions within the default investment, evaluating how risks and trade-offs are balanced, monitoring the exercise of discretion, and documenting decisions in a manner that reflects a disciplined fiduciary process.
The following ten questions are not designed to produce “right answers.” They are intended to surface whether a plan’s default investment is being actively governed or merely assumed. While the questions and related governance considerations are outlined here, several will be explored in greater depth in future insights throughout the year.
1. What problem is our default investment really designed to solve?
Target-date funds are often described as “set-it-and-forget-it” solutions. While they are designed to remove barriers to plan participation and to encourage prudent investment practices, they are, in reality, complex investment structures intended to solve specific problems — problems that may not always align with what a committee believes it is addressing.
Some defaults are designed primarily to maximize long-term wealth accumulation. Others emphasize volatility management near retirement. Some are built around replacement ratio targets, while others are structured to align with peer benchmarks or regulatory considerations. Still others prioritize administrative simplicity or cost minimization.
These objectives imply different views of risk and different trade-offs. A TDF focused on maximizing accumulation, for example, may be more tolerant of higher overall volatility or sequence risk near retirement in furtherance of that objective. This is not a matter of correct or incorrect philosophy. It is a matter of understanding the approach being taken on behalf of participants.
Good governance begins with clarity of purpose. A committee should be able to articulate, in plain language, what the default is intended to accomplish. Without that articulation, performance reviews and fee discussions tend to drift toward generic comparisons rather than alignment with the plan’s own stated objectives.
2. What (and whose) capital market assumptions are embedded in this glide path?
Every TDF glide path reflects a set of assumptions about the future — expected returns, inflation, correlations, participant longevity, risk aversion, and market risk premiums. These assumptions may be explicit in a manager’s research materials or implicit in the fund’s construction. They are always present, regardless.
A committee does not need to develop its own capital market forecasts to govern a default responsibly. It should, however, recognize that selecting a default is, in effect, adopting a particular set of assumptions. Fiduciaries should be able to identify where those assumptions originate, how they are constructed, and how frequently they are reviewed.
In this sense, a default investment is never neutral. It is an expression of a defined investment philosophy and an approach to portfolio construction. Governance requires an awareness of the intellectual foundation on which participant outcomes are being built.
3. How is “risk” defined inside this default — and what risks are prioritized?
“Risk” is one of the most frequently used and least consistently defined terms in retirement plan oversight.
Committees often view risk through the lens of volatility or short-term drawdowns. Participants, however, may experience risk in different ways: the risk of failing to accumulate sufficient retirement income, the risk of making behavioral mistakes during market stress, or the risk of outliving savings.
Different target-date designs emphasize different dimensions of risk. Some prioritize smoothing returns and mitigating near-term volatility. Others may accept greater interim volatility in an effort to address longevity or inflation risk. Some providers may be willing to incur a degree of liquidity risk in exchange for potential return premiums from private markets or alternative investments, while others may conclude that the trade-offs are not warranted.
Governance does not require selecting a “correct” definition of risk. It requires understanding which risks are being prioritized within the default investment and assessing whether that perspective aligns with the committee’s fiduciary philosophy and the objectives of the plan.
4. What degree of discretion does the manager have inside the fund?
Many default investments are described as passive or rules-based. In practice, most TDF structures embed varying degrees of active decision-making.
Discretion may appear in asset class tilts within a defined risk budget, manager selection within a fund-of-funds structure, tactical shifts across market environments, or periodic updates to the glide path itself. Even rebalancing policies and implementation details can reflect judgment rather than mechanical rules.
Indeed, regardless of whether the underlying building blocks are passive or active, the construction of the glide path itself represents a series of active decisions about how risks and objectives are balanced.
From a governance perspective, the issue is not whether discretion exists, but whether it is understood and monitored. Committees should know where flexibility resides, how it is governed internally by the manager, and how material changes are communicated to plan fiduciaries.
5. How are fees evaluated in the context of services?
Fee benchmarking is a standard component of fiduciary oversight. Fee reasonableness, however, is not determined solely by percentiles and peer group comparisons.
Different default structures provide different sets of services. Some deliver only asset allocation and underlying fund management. Others incorporate research support, participant communication tools, risk management overlays, or retirement income features.
Governance evaluates fees in the context of what the plan receives in return. A low-cost structure may be entirely appropriate for a plan that prioritizes simplicity. A higher-cost structure may be reasonable if it aligns with a broader set of objectives and services.
The fiduciary question is not simply, “Is this the least expensive option?” but rather, “Are these fees reasonable in light of what we are asking the default to do?” — and is that conclusion documented.
6. What role does proprietary product usage play, if any?
Many target-date funds are built using a single manager’s proprietary investment products. Others employ open-architecture structures that incorporate multiple external managers.
Neither approach is inherently a virtue or a flaw. It is a structural feature with governance implications.
Proprietary structures may offer efficiency, integration, and cost advantages. They may also limit the range of external options available within the default investment. A well-governed committee recognizes these trade-offs and documents its rationale rather than treating structure as a background detail.
7. How often do we formally revisit the default — and what would trigger a change?
Most committees review their default investment on a calendar basis, alongside the rest of the investment lineup. Others respond primarily to performance concerns or market events.
Governance is strengthened when there is clarity about what would prompt a deeper or more comprehensive review. Examples might include:
Material changes to the glide path or investment process
Persistent deviation from stated objectives
Significant fee changes
Regulatory or litigation developments affecting industry standards
Meaningful shifts in participant demographics or behavior
Changes in plan design or sponsor objectives
Defining these triggers in advance helps transform default oversight from a reactive exercise into a structured governance process.
8. How does this default interact with actual participant behavior?
Target-date funds are typically designed around assumptions about a hypothetical “average” participant. In reality, participant populations vary widely across plans and are shaped by demographics, compensation structures, and organizational culture.
Contribution rates, withdrawal patterns, loan usage, and responses to market volatility can materially influence outcomes. Different default designs may be more or less sensitive to these behaviors.
Good governance considers not only how the portfolio is constructed, but how it is likely to be experienced in practice. This often requires reviewing participant data, communication approaches, and plan design features alongside the investment structure itself.
9. What is documented — and what is merely understood?
Committees often operate with a shared understanding of why a particular default was selected and retained. The governance question is whether that understanding exists in a form that can be reconstructed later.
Fiduciary reviews, regulatory inquiries, and litigation assessments rely on documentation rather than institutional memory. Meeting minutes, policy statements, governance frameworks, and review materials form the permanent record of a committee’s process.
A useful test is whether an independent reviewer, years later, could follow the logic of the committee’s decisions based solely on what has been documented.
10. If we had to explain this default choice in one page to a participant, could we?
This question serves as a test of clarity rather than a communication strategy.
If a committee can explain, in terms understandable to a participant, what the default is designed to do, why it was chosen, and how it is governed, it often reflects a deeper level of internal alignment.
Complex investment structures do not require simplistic explanations. They do require coherent ones.
Conclusion: Governance as an Operating Discipline
As noted at the outset, none of these questions lends itself to a single correct answer. Different defined contribution plans, serving varied participant populations and guided by differing fiduciary philosophies, will reasonably arrive at different conclusions.
What distinguishes strong default oversight is not the selection of a particular fund or structure, but the presence of a documented, repeatable process — one that defines objectives, understands underlying assumptions and risks, monitors discretion, evaluates alignment, and preserves a clear record of decision-making over time.
