Total Social Impact (TSI™) is an innovative approach to measuring corporate responsibility. TSI was invented by Harry Halloran, Steve Dillenburg and Tim Greene, leaders in the fields of corporate governance, business ethics and environmental performance. The TSI approach allows quantitative measurement of corporate responsibility, business behavior and global citizenship. The measurements are captured in the TSI Ratings™ TSI Ratings provide investment managers, insurance underwriters, equity analysts, attorneys, and others with key insights into corporate social responsibility performance. In addition, TSI Ratings are a key tool for Audit Committees seeking Sarbanes-Oxley compliance.
