In this chapter, we investigate whether the first-time issuance of a standalone corporate sustainability report led to changes in reputation as measured by Fortune Most Admired scores. Based on a sample of 59 U.S. companies issuing their first standalone sustainability report over the period from 2001 to 2007, and controlling for the financial “halo effect” reported by Brown and Perry (1994), we find, on average no significant changes in reputational scores. However, cross sectional analysis shows that issuing companies from socially exposed industries experienced decreases in scores. Further, report quality, at least at the extremes appears to be positively related to changes in perceived reputation. These results are consistent with Godfrey's (2005) arguments with respect to corporate reputation.
