Harvard Business School Working Paper, No. 16-023, September 2015.http://nrs.harvard.edu/urn-3:HUL.InstRepos:21444488Under the prevailing ideology of “shareholder primacy” most boards of directors believe that they are prevented from considering stakeholders other than shareholders in determining material issues and materiality for strategy and reporting. New research is showing that legal foundations exist for directors to indeed consider other stakeholders. To many boards, this is new thinking. In order to assist boards in this new realm of taking into account multi-stakeholder significance, we have structured this paper in four parts and a conclusion. In Part I we review fiduciary duty focusing on to whom this duty is owed. In Part II, we review the relevance of materiality in corporate governance. In Part III, we review our audience-focused materiality determination approach and in Part IV we discuss the new idea of an annual board “Statement of Significant Audiences and Materiality.” We conclude with some preliminary research results, ideas for future research, and next steps.en-USResearch Paper or Report2015-09-0110.2139/ssrn.2654199
