The Hidden Fiduciary Risk in Long-Standing Vendor Relationships
The Hidden Fiduciary Risk in Long-Standing Vendor Relationships
Many plan sponsors take pride in maintaining long-term relationships with service providers.
It’s not unusual to hear statements like:
“We’ve worked with them for years.”
“They understand our organization.”
“They’ve always taken good care of us.”
In many cases, these relationships are productive and mutually beneficial.
However, from a fiduciary perspective, longevity alone cannot substitute for periodic evaluation.
Why Long-Term Vendor Relationships Are So Common
Benefit plans are complex programs involving multiple stakeholders, regulatory requirements, and employee expectations.
Once a service provider demonstrates competence and trust, sponsors often prefer stability over disruption.
Long-term relationships offer advantages:
Institutional knowledge of the organization
Familiarity with plan design and employee demographics
Established communication channels
Operational continuity
These benefits are real. But they can also create blind spots.
How Familiarity Can Reduce Oversight
Over time, relationships tend to shift from structured evaluation to informal trust.
Sponsors may begin to assume that:
Fees remain competitive
Services remain aligned with market standards
Vendor incentives remain unchanged
Recommendations remain fully objective
Without periodic review, these assumptions may go untested.
This is where fiduciary exposure can develop — not because something improper occurred, but because the evaluation process gradually disappeared.
What Changes Over Time in the Market
Even when a vendor relationship remains stable, the market around it does not.
Over time:
New service models emerge
Technology capabilities evolve
Fee structures shift
Industry consolidation occurs
Ownership structures change
A vendor that was highly competitive five or ten years ago may still be effective — but that assumption should be validated periodically.
Why Courts Focus on Process, Not Loyalty.
In fiduciary matters, courts and regulators rarely focus on how long a relationship has existed.
Instead, they focus on questions such as:
When was the last formal evaluation conducted?
Were alternative providers considered?
Were fees reviewed relative to the market?
Was the evaluation documented?
A long-standing relationship may be entirely appropriate.
But without evidence of periodic review, it can be difficult to demonstrate that the arrangement remained prudent over time.
What Periodic Evaluation Actually Looks Like
Periodic evaluation does not necessarily require constant disruption or frequent vendor changes.
Instead, it may include:
Independent benchmarking of fees and services
Periodic RFP processes
Documentation of evaluation criteria
Review of compensation structures
Governance discussions among plan fiduciaries
The goal is not to replace vendors unnecessarily, but to confirm that existing relationships remain appropriate.
Compensation Transparency Is Becoming More Important
Strong vendor relationships can be valuable.
However, fiduciary responsibility requires sponsors to balance loyalty with oversight.
A relationship that has been validated through objective evaluation is far stronger — and far more defensible — than one that continues primarily through familiarity.
The Bottom Line
Longevity in a vendor relationship is not a problem.
The absence of periodic evaluation is.
Sponsors who combine stability with structured oversight are better positioned to demonstrate that their decisions remain prudent over time.
