In this study we performed a content analysis on the websites of the Fortune 100 corporations to examine their responses to the terrorist attacks of September 11, 2001. We find that most corporations responded by providing financial assistance in the form of direct cash donations or matching employee contributions. Contributions of products or services, and enhanced security measures were the most frequently provided in-kind responses. Four variables influence the kinds of responses generated by the various companies: industry category, geographic location, physical impact, and profitability. The Industry category financial services, and the Northeast geographic location have the most significant effect on company responses. Physical impact of the tragedy is related to the provision of additional services or security measures. In addition, level of profitability is found to affect both donations to a fund and provision of volunteers. The paper explores some of the reasons behind the pattern of responses we observed and recommends some directions for future research.
