Impact investing

What is Impact investing?

Impact investing intentionally seeks measurable positive social or environmental outcomes alongside a financial return objective.

Impact reporting should include adverse and unexpected outcomes, not only selected success stories. Portfolio aggregation must avoid adding incompatible units, and realized outcomes should be distinguished from forecasts. Financial return, operational output, beneficiary outcome, and systemic impact are related but separate layers of evidence. Each result needs a dated measurement boundary.

Targets should retain their original baseline.

Defining features

Intentionality distinguishes impact from an incidental benefit. Investors identify an outcome, affected population or ecosystem, mechanism, and evidence. Financial expectations can range from capital preservation to market-rate return, but must be explicit. Merely owning a company with beneficial products does not establish that the investment contributed to an additional outcome.

Impact pathway

A theory of change links capital and investor actions to company activities, outputs, stakeholder outcomes, and longer-term impact. Each step has assumptions and external influences. Contribution may come through financing underserved activity, flexible terms, expertise, governance, or engagement. In liquid public markets, additionality is harder to demonstrate and should be described cautiously.

Measurement

Select metrics before investment, establish a baseline and target, define boundary and frequency, and collect comparable evidence. Output, such as loans made, differs from outcome, such as improved financial security. Where possible, assess what would have happened otherwise. Measurement cost and beneficiary privacy matter, and an easy metric should not displace the outcome that motivated the strategy.

Financial and impact risk

Impact investments retain market, credit, liquidity, currency, governance, and valuation risks. They also face impact risk: the intended outcome may not occur, may reach the wrong group, may cause harm, or may be impossible to verify. Exit can weaken mission protections. Portfolio reporting should show financial return and impact evidence separately rather than combine them into an opaque score.

Practical due diligence

Test intentionality, investor contribution, business model, stakeholder need, evidence, additionality, adverse effects, governance, data integrity, and exit. Review incentives and who bears cost or risk. Seek independent assurance where proportionate. Avoid counting the full activity of an enterprise when only a fraction is financed or attributing broad social change solely to invested capital.
