When a classification duration is extended, how are banner markings affected?

When the classification duration of a document or information is extended, the banner markings remain unchanged. The banner markings, which typically indicate the classification level and any pertinent information such as the date of classification, do not reflect the new duration unless the content undergoes a re-evaluation or declassification process. This stability in banner markings ensures continuity and clarity regarding the classification status of the information, even if its duration is extended.

Hence, it is important to maintain a consistent classification marking system, as frequent changes could lead to confusion regarding the sensitivity level of the information involved.
