Pass-through voting is a mechanism allowing institutional investors to delegate voting authority directly to asset managers or custodians without intermediaries, enabling real-time exercise of proxy votes on portfolio securities and enhancing stewardship accountability.
What Is Pass-Through Voting?
Pass-through voting is a stewardship mechanism that allows institutional investors—pension funds, endowments, sovereign wealth funds—to exercise proxy voting authority on their portfolio holdings by transmitting voting instructions directly to custodians or delegated asset managers, who then execute those votes without re-delegating discretion to intermediaries such as proxy advisors or sub-advisers.
Under a pass-through voting arrangement, the asset owner retains ultimate voting authority and defines voting parameters explicitly. Instructions flow from owner to custodian (or owner-delegated manager to custodian) with minimal intermediation. The custodian's role is operational execution, not discretionary judgment. This differs fundamentally from traditional proxy voting workflows, where discretion is passed through multiple intermediaries, creating information asymmetry and divorcing voting intent from voting action.
The term "pass-through" reflects the direct transmission of voting rights and instructions without redistribution of fiduciary authority.
Why Has Pass-Through Voting Gained Institutional Traction?
Pass-through voting has emerged as a stewardship discipline driven by three institutional pressures: the need to operationalize fiduciary standards, the demand for transparent governance, and skepticism about proxy advisor gatekeeping.
Large pension funds have experienced governance failures and voting misalignment. In 2019, research by Tapestry Networks and others highlighted that many institutional investors delegated voting authority without defining explicit voting criteria, leading to votes that contradicted stated ESG or governance policies. CalPERS, managing $468 billion in global equities and alternatives as of 2024, gradually shifted toward pass-through voting models to align proxy voting with its annual Governance and Sustainability Principles. This required developing internal voting research capacity and instructing its custodians—State Street and Northern Trust among them—to execute votes according to CalPERS' explicit framework, not default proxy advisor recommendations.
The UK Stewardship Code (revised 2020) and similar international frameworks have also reinforced the expectation that institutional investors exercise voting authority directly, rather than outsourcing discretion. Signatories to these codes must demonstrate intentional voting strategies, traceable to governance mandates. Pass-through voting creates an audit trail linking voting instructions to policy.
Proxy advisors—particularly Institutional Shareholder Services (ISS) and Glass Lewis—have faced criticism from both asset owners and regulators for concentrated gatekeeping power. In 2020, the SEC cautioned that proxy advisors wielded significant influence over trillions of dollars in votes without uniform transparency or conflict-of-interest disclosure. Pass-through voting reduces dependency on proxy advisor default recommendations by creating direct owner-custodian pathways.
How Does Pass-Through Voting Operate in Practice?
Pass-through voting workflows typically follow this sequence:
First, the asset owner (e.g., a pension fund's investment committee) establishes a voting policy governing ESG, governance, capital structure, and other dimensions relevant to its investment thesis. This policy is documented in writing and communicated to custodians and asset managers.
Second, as proxy statements are filed by portfolio companies, custodians distribute voting materials to the asset owner (or to a delegated asset manager acting under pass-through authority). The owner reviews materials, cross-references them against voting policy, and issues explicit voting instructions to the custodian.
Third, the custodian records the voting instruction, verifies it against the owner's authorization framework, and executes the vote on the record date. The custodian then confirms execution and provides a vote confirmation report to the owner.
Fourth, the owner reconciles vote confirmations with its voting policy to ensure fidelity.
This process requires robust custody infrastructure and defined timelines. Northern Trust, BNY Mellon, and State Street have built pass-through voting workflows into their institutional proxy services. These custodians operate as neutral execution agents, not discretionary fiduciaries; they do not make voting decisions on behalf of owners.
What Is the Relationship Between Pass-Through Voting and Asset Manager Mandates?
Pass-through voting governance becomes more complex when institutional investors delegate portfolio management to external asset managers. Two models exist:
Discretionary mandates with voting policy constraints: The asset manager holds discretionary voting authority but operates within bounds set by the owner's voting policy. The manager may consult proxy advisors for research and recommendations but does not defer entirely to proxy advisor votes. The owner's policy constrains manager discretion.
Pass-through mandates: The asset owner retains explicit voting authority and instructs the custodian (not the manager) on how to vote. The manager may provide voting research and recommendations to the owner, but the owner makes final voting decisions. The manager does not vote; it advises. This model is more labor-intensive for asset owners but preserves voting authority.
Many institutional investors employ hybrid models: pass-through voting on core governance issues (director elections, executive pay, charter amendments) and discretionary manager voting on routine matters or on holdings in pooled vehicles where pass-through voting is operationally infeasible.
The distinction matters for fiduciary accountability. Under discretionary mandates, asset managers bear fiduciary responsibility for voting; under pass-through mandates, asset owners retain that responsibility and must document voting decisions.
Does Pass-Through Voting Apply to Alternative Assets?
Pass-through voting is less standardized in private markets. Limited partners in private equity funds or real estate funds typically have limited voting rights on portfolio companies; general partners exercise control. However, pass-through voting concepts are relevant to LP governance votes (fund amendments, GP removal, fee adjustments).
The Institutional Limited Partners Association (ILPA) has advocated for transparency and pass-through mechanisms for LP votes on material governance issues. Transparency and voting clarity in LPs' interests remain inconsistent across the private markets ecosystem, particularly in private credit and secondary markets, where custody and voting infrastructure is less mature than in listed equities.
What Governance Standards Apply to Pass-Through Voting?
For registered investment advisers, pass-through voting falls under SEC Rule 206(4)-6, which requires advisers to adopt written policies and procedures for proxy voting and to disclose voting records to clients. If an adviser implements pass-through voting, it must document the process and ensure compliance with client mandates.
For pension funds under ERISA, pass-through voting is consistent with fiduciary duty requirements, provided the asset owner documents its voting policy and maintains records of voting decisions.
For custodians, pass-through voting is operationalized through custody agreements that specify voting authority, instruction timelines, confirmation protocols, and liability allocation if votes are executed in error.
Implications for Long-Term Capital Allocators
Pass-through voting reflects a broader institutional shift toward direct stewardship and away from outsourced discretion. For pension funds, endowments, and sovereign wealth funds, pass-through voting enables alignment between long-term investment theses and governance action. It requires investment in voting research capacity and custodial infrastructure, but it clarifies fiduciary accountability and reduces information asymmetry.
Institutional investors implementing pass-through voting should ensure their custodians and asset managers have robust operational capabilities, clear voting instruction protocols, and systems for vote confirmation and reconciliation. They should also document their voting policies in writing and ensure that policies reflect their long-term capital allocation philosophy, not reactive market sentiment.
As institutional investors increasingly face scrutiny over stewardship credibility, pass-through voting is becoming a mark of serious governance practice, not a niche arrangement. Asset owners seeking to demonstrate intentional stewardship—and custodians and asset managers seeking to serve those owners—should treat pass-through voting infrastructure as essential, not optional.
