What does it mean to truly own a company? For most investors, ownership has historically been passive, buy the shares, watch the price, sell when you're done. But a growing body of evidence, regulation, and professional practice argues that real ownership carries deeper responsibilities. That is the world of stewardship and engagement, and it sits at the heart of modern ESG investing.
What Is Stewardship?
The word steward has Old English roots, from "stig" (house) and "weard" (guardian). A steward was the person entrusted to look after an estate on behalf of its owner, obliged to return it in good order and ideally in better condition than they found it.
In investment terms, the concept maps directly. An institutional investor, a pension fund manager, an asset manager, an insurer, does not invest their own money. They invest on behalf of beneficiaries: the pensioners, savers, and clients who have entrusted their capital. The manager is the steward of those assets. Their obligation is not just to generate short-term returns, but to preserve and enhance long-term value on behalf of those they serve.
Stewardship is the process of acting as an active, responsible owner of investment assets to preserve and enhance their long-term value, in line with the interests of clients and beneficiaries. It spans the full spectrum of ownership behaviour, from how capital is allocated to how investors engage with company management and vote at shareholder meetings.
This connects directly to fiduciary duty, the legal and ethical obligation of a person managing another's assets to act in that person's best interests. Fiduciaries must seek to protect and grow the value of the assets they oversee, and return them in good order. Because institutional investors are entrusted with others' capital, fiduciary duty applies to them throughout the investment chain, and stewardship is one of the most important ways they fulfil it.
Stewardship vs. Activism
It is worth distinguishing stewardship from the related but distinct concept of shareholder activism. Activism is typically a specialist strategy where an investor takes a stake in a company specifically intending to drive change, in governance, capital allocation, or business strategy, with the explicit aim of generating investment outperformance. Activist hedge funds are the most recognisable practitioners.
Stewardship, by contrast, is a consequence of investment rather than its starting point. The engaged investor already owns the company for investment reasons, and then acts as a responsible owner to protect and grow that investment over time. Where activism tends to be short-term and focused on extracting value, stewardship aims at long-term value creation and preservation for clients and beneficiaries.
What Is Engagement?
Engagement is the mechanism through which stewardship responsibilities are put into practice. It is purposeful, two-way dialogue with company management and boards, conducted with a specific objective in mind.
Think of a landlord who owns several rental properties. A passive landlord simply collects rent and sells when the price is right. A good steward-landlord maintains the buildings, communicates with tenants, monitors how properties are performing, and takes action when something goes wrong, because they understand that the long-term value of their assets depends on active involvement. Engagement is what the investor-steward does to maintain and improve the "estate" of their portfolio companies.
Engagement can cover the full range of issues affecting long-term business value:
- Strategy, Is the company's long-term plan sound and resilient to climate risk, regulatory change, or shifting consumer behaviour?
- Capital structure, Is capital being allocated wisely?
- Operational performance, How is the company managing its supply chains, workforce, and environmental footprint?
- Risk management, Are material ESG risks being identified and managed?
- Executive pay, Is remuneration aligned with long-term performance and stakeholder interests?
- Corporate governance, Is the board independent, diverse, and genuinely effective?
ESG factors are integral to all of these. A company's approach to environmental risk, its treatment of workers, and the quality of its governance are not peripheral concerns, they are core indicators of long-term business health.
Monitoring vs. Engagement: An Important Distinction
Both monitoring and engagement involve dialogue with companies, but they serve different purposes, and conflating them is a common source of confusion.
Monitoring dialogues are primarily information-gathering exercises. The investor seeks to understand the company's performance and strategy in order to inform buy, sell, or hold decisions.
Engagement dialogues are two-way. The investor is not just learning, they are expressing a view, communicating concerns, and seeking change in company behaviour.
Monitoring vs. Engagement in practice:
- Monitoring: "What are your Scope 3 emissions?", the investor is gathering data.
- Engagement: "We expect you to commit to a Science Based Target by 2025. If you don't, we will vote against your board at the next AGM.", the investor is pressing for a specific, time-bound outcome and signalling the consequences of inaction.
The difference is the objective. Genuine engagement requires a clear target set from the outset. Without one, what looks like engagement can easily become a cover for monitoring, or a justification for holding a position without actually pressing for improvement.
The Investor Forum describes engagement as "active dialogue with a specific and targeted objective… the underlying aim should always be to preserve and enhance the value of assets." The clarity of objective is what separates engagement from monitoring.
Why Does Engagement Matter?
The case for engagement rests on two foundations: evidence that it works, and the argument that it is a fiduciary requirement.
Evidence That Engagement Creates Value
There is a meaningful and growing body of research showing that well-executed engagement generates positive financial returns.
The Hermes Focus Fund study, one of the earliest rigorous analyses, examined the first 41 investments of a dedicated engagement fund launched in 1998. Key findings:
- 65% overall success rate in achieving pre-set engagement objectives
- Outperformed a broad market index by 4.9% net of fees per year
- Approximately 90% of excess return was attributed to engagement-driven outcomes
The Active Ownership study covered over 2,000 engagements with more than 600 companies by a single fund manager (1999-2009). Key findings:
- Successful engagement was followed by positive abnormal financial returns
- For successful climate change engagements: excess return exceeded 10% in the following year
- For ESG engagements overall: abnormal return of 2.3% in the year after initial engagement, rising to 7.1% for ultimately successful ones
- Unsuccessful engagements showed no adverse financial response, the downside of trying was minimal
More recent research also finds that ESG engagement reduces downside risk, with effects strongest for governance-related engagements.
Successful engagements rarely happen after a single meeting. Research suggests it typically takes around 18 months of persistent dialogue before concrete results emerge. Investors who give up after one or two conversations are unlikely to see change, and unlikely to capture the financial upside that successful engagement generates.
Example, Supply Chain Engagement: Boston Common Asset Management conducted a multi-year engagement with a major apparel and footwear company around water risks in its cotton and leather supply chains. During the engagement, the investor submitted, and later withdrew, a shareholder resolution in response to the company's commitment to address the issue. The company improved its relevant reporting, undertook material risk assessment, and signed up to good-practice standards for more sustainable sourcing. This illustrates how engagement, including the threatened use of formal tools, can drive tangible operational change.
Engagement as a Fiduciary Obligation
Beyond generating value, engagement is increasingly recognised as something investors are required to do, as a direct expression of fiduciary duty. When a company's annual general meeting (AGM) comes around, voting resolutions touch on fundamental questions: board composition, audit oversight, executive pay, capital structure. Not engaging thoughtfully with these issues is arguably a failure of the duty investors owe their clients.
The Principles for Responsible Investment (PRI) articulates this through Principle 2, committing signatories to "be active owners and incorporate environmental, social and governance (ESG) issues into our ownership policies and practices."
The Escalation Ladder
Most engagements begin with quiet, private dialogue. Escalation to more forceful measures only happens when the company is unresponsive. This progression, from private conversation to public confrontation, is known as the escalation ladder.
Typical escalation progression:
- Private dialogue, direct, confidential conversation with management or the board
- Collaborative engagement, joining forces with other investors to amplify the message
- Filing a shareholder resolution, making the concern a matter of public record at the AGM
- Voting against directors, withholding support from board members responsible for the failing
- Divestment, selling the position as a last resort, signalled formally so the company understands why
Jumping multiple rungs at once is sometimes necessary in urgent situations, but risks burning the relationship before it needs to be burned.
Example, Engine No. 1 vs. ExxonMobil (2021): Engine No. 1, a small activist-aligned fund holding less than 0.02% of ExxonMobil, ran a proxy campaign arguing the company's long-term strategy was misaligned with the energy transition. By building a coalition with large institutional investors, including BlackRock and Vanguard, Engine No. 1 succeeded in replacing three ExxonMobil board directors with candidates more focused on climate strategy. The campaign is a vivid illustration of how escalation to the top of the ladder, with sufficient coalition support, can produce dramatic governance change even at one of the world's largest companies.
Example, Climate Action 100+: CA 100+ is one of the most significant collective engagement initiatives ever launched. A coordinated group of institutional investors, together representing tens of trillions in assets, targets the world's largest corporate greenhouse gas emitters. For each target company, a lead engager is appointed to coordinate the dialogue. The initiative has achieved notable results, including strategic shifts by major European oil companies (Repsol, Total, ENI, BP, Shell), each of which has materially revised its long-term investment plans. The coordination structure allows consistent, credible messaging across many investors simultaneously.
Key Stewardship Codes and Frameworks
Alongside the commercial and fiduciary case for engagement, a formal regulatory and normative framework has emerged to set standards for stewardship practice globally.
The UK Stewardship Code
The UK developed the world's first national stewardship code in 2010, as a direct response to the 2008 financial crisis. A report by Sir David Walker identified that limited institutional engagement with major banks had failed to constrain the excessive risk-taking that contributed to the crisis. The Financial Reporting Council (FRC) was tasked with creating a framework.
The original 2010 Code set seven principles for institutional investors:
| Principle | Requirement |
|---|---|
| 1 | Publicly disclose stewardship policy |
| 2 | Have a robust, transparent policy on conflicts of interest |
| 3 | Monitor investee companies |
| 4 | Establish clear escalation guidelines |
| 5 | Be willing to act collectively with other investors |
| 6 | Have a clear voting policy and disclose voting activity |
| 7 | Report periodically on stewardship and voting |
The Code was revised in 2012 and fundamentally redrafted in 2020. The 2020 Code represents a major shift: away from statements of intent, toward evidence of outcomes. Signatories can no longer simply publish policy documents, they must now report annually on what they actually did, and demonstrate what changed as a result.
The 2020 UK Stewardship Code also introduced Principle 4, requiring investors to identify and respond to market-wide and systemic risks, such as climate change and the stability of the financial system. This goes beyond company-level engagement to recognise that investors have broader responsibilities for the health of the markets in which they participate.
The UK Code has been highly influential globally. Stewardship codes now exist in over 20 markets, developed by stock exchanges, regulators, or investor bodies.
The Japan Stewardship Code
Japan's Principles for Responsible Institutional Investors, introduced in 2014, were closely modelled on the UK Code. Subsequent revisions extended coverage to all asset classes beyond listed equity, incorporated sustainability and ESG considerations, and encouraged asset owners to take a more active role in overseeing their fund managers' stewardship activities.
The EU Shareholder Rights Directive II (SRD II)
The EU's Shareholder Rights Directive II came into force in 2019, raising stewardship expectations across all EU member states. It requires institutional investors and asset managers to develop and publicly disclose engagement policies covering how they monitor investee companies on ESG matters, and to report annually on implementation. It effectively functions as a regulatory stewardship framework, moving European markets toward binding expectations where previously voluntary codes applied.
The PRI Framework
The Principles for Responsible Investment provide a global normative framework. Principle 2 is the engagement principle. The PRI also provides practical infrastructure for collective engagement through its Collaboration Platform, through which signatories can coordinate campaigns on shared concerns. The PRI's 2018 work identified three dynamics through which engagement creates value: communicative dynamics (information exchange), learning dynamics (building knowledge), and political dynamics (building relationships that enable change).
The US context, ERISA: In the United States, pension fund managers are fiduciaries under the Employee Retirement Income Security Act of 1974 (ERISA). Under ERISA, fiduciaries can engage and vote proxies where doing so is likely to improve the economic value of the investment, including where ESG issues represent significant operational risks in indexed portfolios. However, engagement conducted purely to advance social policy goals, without a clear link to investment value, is not permitted under ERISA's framework.
Stewardship in the Investment Chain
Stewardship responsibilities flow through the investment chain, from the ultimate beneficiary (a pension fund member), through the asset owner (the pension fund), to the fund manager, and then to the investee company. Any party can carry out stewardship activities, but in practice the role concentrates where the greatest scale of assets exists, typically large fund managers.
Asset owners usually discharge their stewardship duties by setting expectations for, and holding accountable, the fund managers they appoint, rather than directly engaging companies themselves.
