Final answer:
Remove the banner markings, creation date, and 'working paper' annotation before sending the document out.
Step-by-step explanation:
Before sending the document out, the banner markings, creation date, and 'working paper' annotation should be removed or changed. These markings are typically used to indicate the document's status as a draft or working version and are not appropriate for a final document. To remove the banner markings, go to the 'Review' tab in Microsoft Word or a similar tool, and look for options to remove the banner or header. Make sure to save a new version of the document without the draft markings before sending it to your colleague.
