Disclosure feedback

We are interested in hearing from you if you have submitted CSR(s) redacted for public disclosure to regulators, and in any feedback that you may have received. The submission of redacted CSRs is new to our industry and our collective understanding of best practice will develop over the coming months and years. The awareness comments included in CORE Reference to indicate ‘primary use CSR’ text portions that should be considered for disclosure impact in the ‘secondary use CSR’ represent our current awareness. With your help, we can refine these over time and with insights you share with us. Please contribute and share your knowledge.

Disclosure feedback will be accepted on an open-ended basis via the Disclosure Feedback page.
