What Is a Managed Account in a 401(k)?
A 401(k) managed account is generally an investment-management service that allocates an individual participant's account among investments already available through the plan. Its strongest case over a target-date fund is not that it is 'personalized,' but that participant-specific information changes the portfolio or savings strategy in a way that is valuable enough to justify the additional fee.

A 401(k) managed account is generally an investment-management service, not a fund. The service takes an individual participant's account and allocates it among investments available through the plan. The real question is not whether the service is "personalized." It is whether participant-specific data change the portfolio enough to justify the additional cost.[1][5][7]
That is a stricter test than the marketing language usually suggests.
A target-date fund can already provide:
- diversification
- rebalancing
- age-based risk reduction
- professional portfolio management.
A managed account needs to add something meaningful beyond that baseline.
The Service Manages the Account, Not a Separate Pooled Fund
A target-date fund pools many investors into one portfolio.
A managed account usually works differently.
The participant continues to own positions in plan investments such as:
- U.S. equity fund
- international equity fund
- bond fund
- stable-value fund
- real-asset fund
- other designated investment alternatives.
The management service decides how much of the participant's account goes into each.
Example: One Account, Existing Plan Funds
Plan menu:
- U.S. stock index
- international stock index
- small-cap fund
- bond index
- inflation-protected bond fund
- stable value.
Managed-account service assigns:
- 48% U.S. stock
- 17% international stock
- 5% small cap
- 20% bond index
- 5% inflation-protected bonds
- 5% stable value.
No new pooled fund had to be created.
The service changed the participant's allocation.
The Allocation Can Change Over Time
A discretionary service can:
- rebalance
- reduce or increase risk
- change fund weights
- respond to updated participant information
- change allocations as retirement approaches.
That ongoing authority is one reason the service can cost more than a static investment recommendation.
The provider is not merely saying:
"Consider 70% stocks and 30% bonds."
It can actually implement the covered allocation.
Managed Account Is Not the Same as Advice
The distinction is authority.
Advice
Provider recommends:
60% stocks / 40% bonds.
Participant decides whether to act.
Discretionary management
Provider has authority under the arrangement to implement and maintain the allocation within its mandate.
The participant delegates the investment decision.
That can create a different ERISA fiduciary structure.
Discretion Creates Fiduciary Status
ERISA Section 3(21) provides that a person is a fiduciary to the extent the person exercises discretionary authority or control over plan management or authority/control over plan assets, among other functional tests.[2]
A discretionary managed-account provider therefore cannot avoid fiduciary analysis by calling the service:
- guidance
- coaching
- portfolio help.
Function controls.
Section 3(38) Is a More Specific Status
INV-133 covers Section 3(38) in depth.
An ERISA investment manager must:
- have power to manage, acquire or dispose of plan assets
- satisfy specified regulatory-status requirements
- acknowledge fiduciary status in writing.[2]
Qualifying categories include specified:
- registered investment advisers
- banks
- insurance companies.[2]
A provider can be an ERISA fiduciary without automatically satisfying every Section 3(38) requirement.
Do not treat the two labels as synonyms.
Defaulted Managed Accounts Have an Explicit Fiduciary Structure
The default-investment regulation is more specific.
A qualified default investment alternative generally must be managed by one of the entities described in paragraph (e)(3), including:[1]
- ERISA Section 3(38) investment manager
- qualifying trustee
- plan sponsor or qualifying employee committee that is a named fiduciary.
For an outsourced commercial service used as the plan default, the Section 3(38) structure is therefore especially important.
When Can the Service Qualify as the Plan's QDIA?
29 CFR 2550.404c-5(e)(4)(iii) expressly recognizes an:
investment management service
as a potential qualified default investment alternative.[1]
The service must allocate an individual's plan account using:
- generally accepted investment theories
- diversified exposure designed to minimize the risk of large losses
- a mix of equity and fixed-income investments
- varying degrees of long-term appreciation and capital preservation.[1]
The allocation is based on:
- age
- target retirement date
- life expectancy.[1]
The account should become more conservative with increasing age under the regulatory framework.
The Default-Investment Rule Does Not Require Deep Personalization
This is one of the most important details in the regulation.
For this managed-service default, asset-allocation decisions are not required to take into account:
- individual risk tolerance
- outside investments
- other participant preferences.[1]
That means:
"professionally managed default"
does not legally mean:
"complete personalized financial plan."
Age Can Be Enough for the Regulatory Framework
Suppose two participants are both:
45 years old
with the same target retirement age.
The service has no other participant data.
The regulatory framework can still permit the service to create age-based allocations that satisfy the regulatory design.[1]
That may be legally sufficient.
Its incremental economic value over a good target-date fund is another question.
This Creates the Personalization Gap
The word:
personalized
can describe several very different services.
Level 1: Age only
Uses age or target retirement date.
Level 2: Plan data
Uses:
- salary
- account balance
- deferral rate
- employer match
- contribution source
- plan investment lineup.
Level 3: Broader retirement data
Adds:
- pension
- Social Security assumptions
- spouse information
- expected retirement age.
Level 4: Outside balance sheet
Adds:
- IRA
- taxable investments
- outside employer stock
- other household assets.
Two providers can both sell:
managed account
while operating at different levels.
Available Data and Used Data Are Different
A recordkeeper may possess:
- date of birth
- salary
- contribution rate
- plan balance
- loan balance.
That does not prove the managed-account algorithm uses all five.
The correct diligence question is:
Which data fields actually change the recommendation or managed allocation?
That answer should be documented.
Data With No Decision Rule Add No Personalization
Suppose the system asks about:
- home value
- spouse age
- risk tolerance.
But its portfolio algorithm changes only when:
- age
- retirement year
change.
The questionnaire feels personal.
The portfolio is not materially more personalized.
Data collection and decision use are different.
Example: Age-Only Managed Account
Participant:
- age: 32
- retirement age: 65
- no other data used.
Managed account:
90% stocks / 10% bonds
Comparable target-date fund:
roughly the same 90/10 stock-bond mix
Managed-account fee:
0.40%
Target-date fund additional management cost:
0.08%
If the service does nothing else material, the participant is paying:
32 basis points more
for nearly the same allocation.
That deserves scrutiny.
Example: Additional Data Changes the Decision
Participant:
- age: 58
- plans to retire at 62
- substantial defined benefit pension
- 401(k) concentrated in employer stock
- spouse has large bond portfolio
- participant has low outside equity exposure.
A managed account that can actually incorporate those facts may recommend something meaningfully different from a generic:
2030 target-date fund.
Now the personalization can be economically relevant.
The fee still needs to be justified.
Outside Assets Are Valuable Only if They Stay Current
Participant enters IRA balance:
$300,000
at enrollment.
Five years later the IRA is:
$700,000
and has shifted heavily into technology stocks.
If the managed account still uses the old figure, the service is personalized to a stale household.
A high-quality process needs:
- data refresh
- participant prompts
- clear default assumptions when data are missing.
Personalization decays.
Retirement Date Is Not a Permanent Fact
A participant initially plans to retire at:
67.
Later:
- health
- job change
- pension eligibility
- family obligations
move the expected retirement date to:
62.
If the provider does not receive the update, its de-risking path can remain tied to the wrong horizon.
An account cannot be more current than its inputs.
Managed Accounts Can Also Influence Savings Decisions
Some services do more than allocate investments.
They may provide or implement recommendations involving:
- contribution rate
- employer-match capture
- retirement readiness
- retirement age assumptions
depending on the service and plan design.
That can create value not captured by comparing investment returns alone.
But the sponsor should distinguish:
investment management
from:
savings-rate advice or plan-design effects.
Do Not Credit the Service for Automatic Plan Features
Suppose participants in managed accounts save more because the plan simultaneously introduced:
- automatic enrollment
- automatic escalation
- stronger match.
Those savings improvements should not all be attributed to the managed account.
A monitoring process should isolate what the service actually caused.
The Fee Stack Has Multiple Layers
A managed-account participant can pay:
Service fee
Example:
0.40% of managed assets.
Underlying investment expenses
Example weighted average:
0.07%.
Plan administration
Example:
$60 per year.
Practical cost is not simply:
0.40%.
Example: $250,000 Account
Managed-account fee:
0.40%
Annual service cost:
$1,000
Underlying weighted investment expense:
0.08% = $200
Annual plan administration:
$60
Approximate total:
$1,260 per year
before other participant-specific charges and balance changes.
The relevant comparison is the incremental cost versus the alternative the participant would otherwise use.
Compare Incremental Cost, Not Gross Cost
Suppose target-date alternative costs:
0.12%.
Managed account:
- service fee: 0.35%
- underlying funds: 0.06%
Managed-account investment/service total:
0.41%.
Incremental cost versus target-date fund:
0.29%.
On:
$400,000
that is approximately:
$1,160 per year.
The question becomes:
What does the participant receive for that extra $1,160?
Fees Compound
A small annual fee difference does not remain small over decades.
Assume:
- $250,000 balance
- 20-year horizon
- 6% gross annual return
- no contributions for simplicity.
Cost difference
Managed account costs 0.30% more per year than the alternative.
Approximate ending values:
- 6.00% net: about $801,784
- 5.70% net: about $756,088
Difference:
about $45,700
before taxes and ignoring cash flows.
The exact result depends on returns and contributions.
The principle does not.
A Higher Fee Can Still Be Rational
Cost alone does not decide the question.
A managed account could justify additional expense through:
- materially better diversification
- elimination of concentrated employer stock
- appropriate risk reduction
- improved contribution rate
- better use of employer match
- retirement-income coordination
- disciplined rebalancing
- participant-specific allocation.
The fiduciary should demand evidence that the service actually performs those functions.
404a-5 Treats Advice Fees as Individual Expenses
The participant-disclosure rule expressly lists:
fees for investment advice
among examples of individual expenses that may be charged to a participant account when not already reflected in a designated investment alternative's operating expenses.[3]
A separately charged managed-account service fee can fall within that individual-expense framework depending on how the service is structured.
Participants should know:
- what can be charged
- how the fee is calculated.
Actual Dollar Charges Generally Show Quarterly
For covered individual expenses, 404a-5 generally requires a quarterly statement showing:
- dollar amount actually charged
- description of the service.[3]
Example:
Managed account service — $212.50
is more useful than requiring the participant to reverse-engineer an annual asset-based rate.
Changes to the Fee Need Advance Disclosure
When the applicable annual individual-expense information changes, the regulation generally calls for notice:
30 to 90 days
before the effective date, subject to the unforeseeable-event exception.[3]
A managed-account provider increasing:
0.30% → 0.45%
should not rely solely on the next annual statement.
The pricing change affects the participant's decision to remain enrolled.
The First 90 Days Have a Different Fee Rule
The default-investment regulation generally prohibits specified:
- restrictions
- fees
- expenses
associated with a participant-directed transfer or permissible withdrawal during the first:
90 days
after that participant's first investment in the qualified default alternative.[1]
But ordinary ongoing expenses of operating the investment or service can continue when they:
- do not depend on exit
- do not vary because the participant transfers out.[1]
That distinction matters when the service is used as the default.
A Management Fee Is Not Automatically an Exit Fee
Participant is defaulted into managed account.
Service charges:
0.30% annualized
while assets are managed.
Participant exits on day 60.
The rule does not require the service to have been free for those 60 days merely because the participant later transferred out.
The prohibited category is the special:
exit-related charge or restriction
described by the regulation.[1]
The Default Notice Must Describe Fees
The required default-investment notice must describe:
- investment objectives
- risk/return characteristics
- fees and expenses
of the default alternative.[1]
For a managed account, that should make the service economics understandable.
A participant should not discover an asset-based advisory charge only after reviewing a quarterly statement.
The Provider's 408b-2 Disclosure Matters to the Sponsor
Covered service-provider rules require applicable providers to disclose to the responsible plan fiduciary information including:
- services
- fiduciary status
- registered-investment-adviser status when applicable
- direct compensation
- indirect compensation
- certain related-party compensation
- termination compensation.[4]
That information is essential when evaluating managed-account economics.
Ask Who Gets Paid When the Allocation Changes
A provider can have relationships with:
- recordkeeper
- affiliated asset manager
- underlying funds
- subcontractors.
The committee should understand whether compensation changes when the model uses:
- Fund A
- Fund B
- proprietary option
- unaffiliated option.
A conflict is not automatically a prohibited transaction.
It is automatically a diligence question.
Affiliated Funds Require a Better Explanation
Suppose the managed-account provider allocates:
80%
of participant assets to affiliated funds.
Possible explanations:
- those are the only plan options
- affiliated funds are competitively priced
- provider has no economic incentive tied to use
- fiduciary exemption/structure addresses conflict.
Or:
- provider earns more when affiliated funds are selected.
The committee needs the compensation map.
Do not infer neutrality from the algorithm label.
Managed Account vs. Target-Date Fund
| Issue | Managed account | Target-date fund |
|---|---|---|
| Legal/economic form | Investment-management service | Pooled investment product/portfolio |
| Portfolio unit | Individual participant account | All investors in same target-date vehicle |
| Uses age/retirement date | Common | Core design |
| Can use additional participant data | Yes, service-dependent | Usually limited |
| Rebalancing | Individual account | Inside pooled fund |
| Outside assets can affect allocation | Possible if service accepts/uses them | Generally no |
| Separate service fee | Common | No separate managed-account fee |
| Underlying fund expenses | Yes | Yes, directly/indirectly |
| QDIA eligible | Yes if requirements met | Yes if requirements met |
| Participant data maintenance | Important | Less participant-specific |
The strongest managed-account case appears where the left column is actually different.
Discretionary Management vs. Point-in-Time Advice
| Feature | Managed account | Advice tool |
|---|---|---|
| Recommends allocation | Yes | Yes |
| Implements without trade-by-trade participant approval | Usually, within mandate | Generally no |
| Rebalances automatically | Often | Participant may need to act |
| Ongoing discretion | Yes when structured as discretionary | No |
| Fiduciary status | Depends on function; discretion is a direct fiduciary trigger | Current investment-advice fiduciary rules must be analyzed separately |
| Separate fee | Common | May or may not |
Read the service agreement.
"Advice" and "management" are not interchangeable product labels.
Current Law: The 2024 Advice Rule Was Vacated
DOL's 2024 Retirement Security Rule revised when investment advice would create fiduciary status.
Federal courts vacated that rule and related exemption amendments.
DOL published notice of the vacatur in:
March 2026.[9]
The Department's current website confirms the rule is vacated.
Do not use the 2024 rule as operative law when analyzing a 2026 managed-account arrangement.
The Vacatur Does Not Eliminate Discretionary Fiduciary Status
This point is easy to miss.
The litigation involved the investment-advice definition.
ERISA's statutory fiduciary definition separately covers discretionary authority or control over plan assets.[2]
A genuinely discretionary managed-account service therefore cannot assume the advice-rule vacatur removes fiduciary status.
Different trigger.
What Does the Provider Actually Know?
A useful diligence grid:
| Data | Available? | Used in model? | Participant can update? | Material effect? |
|---|---|---|---|---|
| Age | Yes | Yes | Limited | Usually |
| Target retirement date | Often | Often | Yes | Usually |
| Salary | Often | Service-dependent | Via payroll | Can |
| Contribution rate | Often | Service-dependent | Yes | Can |
| Account balance | Yes | Often | Automatic | Can |
| Pension | Sometimes | Service-dependent | Usually participant | Can |
| Social Security assumption | Often modeled | Service-dependent | Sometimes | Can |
| IRA | Usually not automatic | Optional | Participant | Can |
| Spouse assets | Usually not automatic | Optional | Participant | Can |
| Risk tolerance | Service-dependent | Service-dependent | Yes | Can |
| Employer stock outside plan | Often unknown | Optional | Participant | Can |
The table forces one important distinction:
data availability is not decision relevance.
The Incremental-Personalization Test
Compare the managed account against the best reasonable lower-cost baseline.
Step 1: Establish baseline
Example:
Target-date 2045 fund
- 70% equity
- 30% fixed income
- cost 0.10%.
Step 2: Record managed-account portfolio
Example:
- 66% equity
- 34% fixed income
- service + underlying cost 0.42%.
Step 3: Identify why the allocations differ
Was it:
- pension
- savings rate
- retirement date
- outside assets
- risk constraint?
Or just a different model assumption?
Step 4: Quantify incremental cost
Difference:
0.32%.
Step 5: Identify service value
Does provider also deliver:
- savings-rate optimization
- retirement-income planning
- company-stock reduction
- individualized rebalancing?
Step 6: Ask whether the differences are material
If portfolio and behavior are nearly identical, the fee case is weak.
This is more useful than debating whether managed accounts are generally "good."
Example: Personalization Adds Almost Nothing
Participant:
- age 40
- retirement at 65
- no outside information provided.
Target-date baseline:
85% equity / 15% fixed income.
Managed account:
83% / 17%.
Incremental annual fee:
0.35%.
There may be little economic distinction.
A plan sponsor using that service as default should be able to explain what participants receive beyond two percentage points of allocation difference.
Example: Personalization Changes Several Decisions
Participant:
- age 60
- $900,000 plan balance
- $70,000 annual pension starting at 65
- $400,000 IRA mostly in bonds
- intends retirement at 63
- high employer-stock concentration in plan.
Managed service:
- reduces company stock
- holds more diversified equity in 401(k)
- adjusts fixed income because household pension and IRA already create substantial defensive exposure
- recommends higher contribution for final working years.
Now the service is doing work a basic target-date fund cannot do.
That is a stronger value proposition.
Managed Accounts Can Become Less Personalized Over Time
A provider's initial onboarding can be impressive.
Then:
- participant ignores refresh requests
- salary changes
- spouse retires
- pension election changes
- outside assets move
- retirement date shifts.
The account can slowly become a model built around yesterday's household.
Monitoring should include data freshness, not merely enrollment.
Sponsor Monitoring Should Measure Engagement Carefully
High participant login rate is not investment success.
Low call-center use is not failure.
Useful service metrics can include:
- percentage of participants with complete data
- age of participant-entered data
- allocation dispersion versus target-date baseline
- percentage receiving savings-rate changes
- percentage capturing full employer match
- opt-out rates
- fees
- participant complaints.
The metrics should reflect the promised service.
Performance Is Harder to Benchmark
A mutual fund has:
- one portfolio
- one NAV
- one return stream.
Managed-account participants can differ in:
- age
- contribution rate
- cash flow
- retirement date
- data inputs
- investment allocation
- time enrolled.
A single average return can be misleading.
Do Not Let "Personalized" Eliminate Benchmarking
Harder does not mean impossible.
Possible monitoring approaches:
- compare model portfolios with appropriate blended benchmarks
- compare participant cohorts with target-date baselines
- measure net-of-fee outcomes
- test allocation consistency
- review tracking of model decisions
- compare fee levels across providers
- evaluate participant-specific improvements promised by the service.
A provider should be able to explain how the sponsor can judge it.
GAO Identified This Problem More Than a Decade Ago
GAO's 2014 managed-account report found that:
- fees varied materially
- outcomes could vary
- participants often lacked comparable performance information
- sponsors lacked consistent tools for selecting and overseeing providers.[7]
GAO recommended more DOL guidance.
That recommendation remains relevant.
The GAO Recommendation Was Still Open in 2026
GAO's current recommendation status says that in:
April 2026
DOL reported that it was considering how to address managed-account oversight in connection with broader participant-directed investment rulemaking.[7]
The recommendation remained:
open.
That is an important practical signal.
There is no comprehensive DOL managed-account selection checklist comparable to a dedicated modern rulebook.
Sponsors still need to build a disciplined process from general fiduciary principles and existing disclosure and qualified-default rules.
A Sponsor Should Consider More Than One Provider
GAO specifically recommended that DOL guidance address the importance of considering multiple providers when selecting a managed-account service.[7]
That is sensible even without a dedicated regulation.
Compare providers on:
- fiduciary role
- methodology
- data inputs
- fees
- conflicts
- recordkeeper integration
- participant experience
- reporting
- performance methodology
- cybersecurity.
Convenience is not a substitute for comparison.
Recordkeeper Integration Can Create Lock-In
The easiest managed-account provider may be the one already integrated into the recordkeeping platform.
That can reduce:
- implementation cost
- data-transfer friction
- participant-login complexity.
It can also reduce competitive pressure.
Ask:
- Can another provider integrate?
- What data can leave the platform?
- What happens after recordkeeper change?
- Are fees tied to exclusivity?
- Who owns participant-entered data?
Integration is a benefit.
It can also be a switching cost.
Cybersecurity Matters Because Personalization Uses More Data
The service may collect information beyond ordinary recordkeeping.
Examples:
- spouse information
- outside assets
- retirement goals
- income
- pension data.
A provider therefore creates both:
- investment-management dependency
- data-security exposure.
DOL's general service-provider guidance calls for attention to cybersecurity practices when selecting and monitoring providers.[5]
Personalization expands the data surface.
Default Status Does Not Mean DOL Approved the Provider
Qualified-default status is a regulatory category.
It does not mean:
- DOL reviewed the provider
- DOL endorsed the algorithm
- DOL approved the fee
- DOL certified the portfolio.
Selection of the provider remains the plan fiduciary's responsibility, as does ongoing monitoring.[1][8]
That responsibility is explicit in the governing regulation.
Participant Can Still Move Out
The default framework assumes the participant had an opportunity to direct investments but did not.[1]
The regulation also requires the ability to transfer assets out of the default investment with specified frequency and protections.[1]
The default is not permanent consent to professional management.
A participant can make a different election.
Opt-In and Defaulted Participants Are Different Populations
Opt-in
Participant affirmatively chooses the managed service.
Defaulted participant
Participant can enter the service because no investment direction was provided.
Those groups may have different:
- engagement
- data completeness
- fee awareness
- expectations.
A sponsor should not assume evidence from engaged opt-in users proves equal value for passive defaulted participants.
Defaulted Participants Can Have the Least Data
This is an important paradox.
A managed service used as the default is supposed to provide an individualized account structure.
But the people who do not make an investment election may also be the least likely to:
- complete questionnaires
- link outside assets
- update retirement goals.
The service can therefore default to:
- age
- target retirement age
- plan balance
for exactly the participants who are paying for personalization.
That deserves monitoring.
A Dynamic QDIA Can Change the Comparison
Some plans use:
- target-date fund initially
- managed account later
when richer participant data become available or the participant reaches a specified age.
The regulatory and fiduciary analysis depends on the actual arrangement.
The economic logic can be stronger than defaulting every participant into the highest-cost personalized service on day one.
The question becomes:
When does added information become valuable enough to justify added cost?
The Cheapest Option Is Not Automatically Best
A managed account could produce superior participant outcomes even at a higher fee.
A target-date fund could deliver adequate diversification at a fraction of the cost.
There is no categorical answer.
The fiduciary needs:
- comparable facts
- fee math
- provider methodology
- participant population analysis.
The evidence should decide.
Managed Account vs. Self-Directed Portfolio
A sophisticated participant can manually do many of the same tasks:
- allocate
- rebalance
- change risk
- coordinate outside assets.
That can avoid the service fee.
But it creates:
- time cost
- behavioral risk
- execution burden
- need for continuing review.
The managed account is partly a delegation product.
The value of delegation differs by participant.
What Should a Participant Check Before Enrolling?
- What is the annual service fee?
- What underlying investment expenses remain?
- Which personal data does the provider use?
- Which data can be updated?
- How often is the allocation reviewed?
- Does the service change contribution rate or only investments?
- Does it consider outside assets?
- Are affiliated funds used?
- Can the participant opt out easily?
- What would the comparable target-date fund cost?
The comparison should be concrete.
What Should a Fiduciary Obtain Before Selection?
Authority
- service agreement
- ERISA fiduciary acknowledgment
- Section 3(38) status if applicable
- scope of discretion.
Methodology
- investment theory
- data inputs
- asset-allocation engine
- rebalancing rules
- de-risking rules.
Economics
- participant service fee
- underlying fund expenses
- indirect compensation
- affiliated-fund economics
- termination charges.
Operations
- recordkeeper integration
- participant data flow
- data refresh
- trade implementation
- opt-out process.
Monitoring
- provider reporting
- cohort results
- net-of-fee analysis
- benchmark methodology
- complaints
- cybersecurity.
The service agreement should tell the same story as the participant brochure.
What Should Ongoing Monitoring Test?
Is the fee still competitive?
Assets may have grown enough to renegotiate.
Is personalization real?
Measure how often participant-specific data materially change allocations.
Is data current?
Review completeness and staleness.
Are conflicts controlled?
Monitor affiliated investment usage and compensation.
Is implementation accurate?
Sample participant accounts against model instructions.
Are outcomes understandable?
Review net-of-fee cohort results and savings behavior.
Are participants leaving?
High opt-out or cancellation rates can reveal poor fit or pricing.
Has the service changed?
Algorithms, personnel, assumptions and plan integrations can change without a new product name.
A Better Managed-Account Benchmark
Do not ask:
"Did managed-account participants earn more than the S&P 500?"
That ignores:
- age
- risk
- bonds
- cash flows.
Use a three-part benchmark.
Portfolio benchmark
Did the implemented allocation perform as expected relative to an appropriate blended benchmark?
Baseline benchmark
How did the participant's allocation and outcome differ from a reasonable target-date or other low-cost default?
Service benchmark
Did the provider deliver the personalization, rebalancing, savings or retirement-planning functions for which it was hired?
That framework evaluates both investment and service.
Frequently Asked Questions
What is a managed account in a 401(k)?
It is generally an investment-management service that allocates an individual participant's account among investments available through the plan and can manage those allocations over time.
Is the managed arrangement itself a mutual fund?
No.
The provider usually manages the participant's positions in underlying plan funds or other investment alternatives.
How does it differ from a target-date fund?
A target-date fund is generally a pooled portfolio shared by investors in the same vintage. Professional account management instead changes one participant's allocation and can use participant-specific data.
Are outside assets always incorporated?
No.
The provider can use only information available to and actually incorporated by the provider's methodology.
Must a professionally managed default consider risk tolerance?
No.
The qualified-default regulation says the allocation is not required to take into account individual risk tolerances, investments or other preferences.[1]
Can the provider use more information than age?
Yes, depending on the provider. The default-investment rule sets a qualifying framework; it does not prohibit a provider from using relevant additional participant information when the methodology is designed to use it.
Can professional account management qualify as a QDIA?
Yes.
29 CFR 2550.404c-5 expressly recognizes a qualifying investment-management service as a potential qualified default investment alternative.[1]
Who must manage it when used as the QDIA?
The regulation requires management by a fiduciary described in paragraph (e)(3), such as a Section 3(38) investment manager, qualifying trustee, or named-fiduciary sponsor/committee.[1]
Is every discretionary provider automatically a Section 3(38) manager?
No.
Discretion can create fiduciary status, but Section 3(38) also requires statutory qualification and written acknowledgment.[2]
What does professional account management cost?
Pricing varies. The provider can charge an asset-based or other fee, while underlying plan investment expenses and ordinary plan costs can continue.
If the fee is 0.40%, what does that mean?
On a $250,000 managed balance, 0.40% is approximately $1,000 annually before balance changes.
Does the management fee include fund expenses?
Not necessarily.
Review the provider disclosure and underlying investment expenses separately.
Will the fee appear on the quarterly statement?
Covered participant-specific fees actually charged to the account generally must be disclosed in dollar terms at least quarterly under 404a-5.[3]
Can the defaulted arrangement charge a fee during the first 90 days?
Ordinary ongoing management expenses can apply when they are not imposed or varied because the participant exits. The qualified-default rule restricts specified transfer- and withdrawal-related charges during the first 90 days.[1]
Does qualified-default status protect the sponsor from every claim?
No.
The plan fiduciary still must prudently select and monitor the default arrangement.[1]
How should professional management be compared with a target-date fund?
Compare:
- actual allocation
- participant data used
- services
- underlying investments
- total cost
- net-of-fee value.
If personalization does not materially change the decision, the higher fee needs a stronger justification.
Has DOL issued detailed modern guidance specifically for managed-account provider selection?
GAO has long recommended more specific DOL guidance. As of April 2026, GAO reported that the recommendation remained open and DOL was considering it in broader participant-directed investment rulemaking.[7]
Does the 2024 Retirement Security Rule govern current managed-account advice in 2026?
That rule and associated exemption amendments were vacated by federal courts, and DOL published notice of vacatur in March 2026.[9] Current advice-fiduciary analysis should not assume the vacated rule remains operative.
The ROIStreet Incremental-Personalization Test
Start with the best reasonable lower-cost baseline → record the baseline allocation and total cost → identify every participant-specific data field available to the managed-account service → separate data collected from data actually used → identify which inputs materially change asset allocation, savings recommendations or retirement assumptions → calculate the managed-account service fee in dollars → add underlying investment and plan costs → calculate the incremental cost over the baseline → identify whether the service solves a problem the baseline cannot solve → test data freshness → identify affiliated-fund and compensation conflicts → verify discretionary authority and fiduciary status → compare net-of-fee outcomes using appropriate participant cohorts rather than a single market index → review opt-outs, complaints and implementation errors → renegotiate or replace the service if personalization is thin relative to cost
The right question is not:
"Is professional management worth paying for?"
It is:
"What decisions does this service make differently because of this participant's actual circumstances, and are those differences worth the incremental fee?"
If the answer is unclear, the word personalized is doing more work than the service.
