The objective of this research is twofold: fi rst, to analyze descriptively the type of social information disclosed and the degree to which multinational corporations (MNCs) disclose it, and second, to empirically test whether there are differences in the reporting policy of this type of company according to the audience (global or local), and to discover the factors that explain these differences. A sample of 26 non-Spanish MNCs operating in Spain was selected from the Spanish Merco reputation index in the period 2004-2007. The results show that there are very signifi cant differences in the degree of disclosure and the type of social information reported by MNCs for each audience, and that a company's visibility and resources, in this order, are relevant factors in explaining these differences. crucial impact on society as well as a potential impact on other fi rms (Kolk et al., 2001), its study would be of great interest to academics.Consequently, the objective of this research is twofold: fi rst, to analyze descriptively the type of social information disclosed and the degree to which MNCs report it, and secondly, to empirically test whether there are differences in the reporting policies of this type of company according to the audience (global or local), and to discover the factors that may explain these differences. The structure of this study is as follows: fi rst of all, there is a theoretical analysis concerning the concept of social information and the factors for its disclosure, in which the research question and hypotheses used to test it are established; the methodology used for the research is then presented; and fi nally, the results are analyzed and the main conclusions of this research are drawn.
