Institutional investors are organisations, such as pension funds, insurance companies and investment funds, that invest large sums on behalf of others. Because they own most UK listed shares, they play a key governance role: they vote, engage with boards and intervene over issues such as strategy, poor performance, acquisitions, director pay and weak controls.
Main types
| Type | Whose money | Typical horizon |
|---|---|---|
| Pension funds | Workers' retirement savings | Long term |
| Insurance companies | Policyholders' premiums | Long term |
| Unit trusts and OEICs | Pooled savings of individual investors | Varies |
| Investment trusts | Shareholders in a listed investment company | Varies |
| Private equity and hedge funds | Wealthy individuals and institutions | Shorter, active |
When to intervene: eight triggers
Chapter 10 of the book lists eight situations where intervention may be justified:
| Trigger | Example |
|---|---|
| Strategy | Disagreement with the products or markets the company is pursuing |
| Operational performance | Results persistently below expectations |
| Acquisitions | An overpriced or poorly fitting takeover |
| Disposals | Selling a valuable business cheaply |
| Remuneration | Director pay out of line with performance |
| Internal controls | Failures in health and safety, quality or financial controls |
| Succession planning | No plan to replace key executives |
| Social responsibility | Poor environmental or social conduct |
How they intervene

Institutional investors in ACCA SBL
This sits in governance (syllabus area B). Typical tasks: an investor unhappy with a planned acquisition or a CEO's bonus. Explain whether intervention is justified using the triggers, recommend the escalation step that fits, and consider the investor's own duty to its beneficiaries. Link to agency theory and director pay.
