Background: Corporate Responsibility is not a new concept however in recent times more companies are starting to use different kinds of responsibility disclosures. These disclosures are voluntary and corporations may use them in the way they find suits them best. There is a lot of research in this field and there is no single explanation for what Corporate Responsibility is and how corporations should relate to it.

Purpose: The purpose of the study is to examine the relationship between the controlling owners of corporations and CSR disclosure.

Method: We use a content analysis and a survey study to examine the relationship between corporate controlling owners and the CSR disclosure.

Conclusions: Our results show that controlling owners have little effect on the different dimensions of CSR disclosure. We have however found some differences between the different owner categories where some categories are found to use CSR disclosure to a greater extent.
