The proposed 2017 U.S. Financial Reporting Taxonomy (Taxonomy) contains updates for accounting standards and other improvements since the 2016 Taxonomy as used by issuers filing with the U.S. Securities and Exchange Commission (SEC). We encourage all interested parties to review and provide feedback on this Proposed 2017 Taxonomy. The 60-day comment period was intended to solicit feedback on these updates from users of the Taxonomy and to provide SEC filers, service providers, software vendors, and other interested parties the opportunity to become familiar with and suggest revisions to the Taxonomy.

Users should read the release notes and other guidance and supporting materials provided below which contain details of the changes. All comments are tracked and reviewed for inclusion in the final 2017 Taxonomy release. Comments are acknowledged when received but it is not possible to respond directly to individual comments. Individuals providing comments on the Taxonomy are required to register with a “user name” and email address. Please note that all comments will be visible to other registered users. Guidance for using the Taxonomy viewer/commenting tool is provided here.
