Crossmark is an initiative to provide a standard way for readers to locate the current version of a piece of content. By applying the Crossmark button, JPM is committing to maintaining the content it publishes, and to alerting readers to changes if and when they occur. Clicking on the Crossmark button will tell readers the current status of a document, and may also give readers additional publication record information about the document (https://www.crossref.org/documentation/crossmark/crossmark-policy-page/).
