Time Partners created the External Rate of Return with the London School of Economics to measure a company or investment’s purpose and wider impact on society, the economy, and the environment.

The ERR is designed to be a simple, holistic concept allowing companies, investors and third parties to report their activities comprehensively and transparently across a range of parameters.

Promoting radical transparency, the ERR encourages companies to track the total external outcomes of their activities and act accountably.
