It identifies the duration of time for which the information should be maintained or "retained", irrespective of format (paper, electronic, or other). Retention periods vary on different types of information, based on content and a variety of other factors including: internal organizational need, regulatory requirements for inspection or audit, legal statutes of limitation, involvement in litigation, taxation and financial reporting needs, as well as other factors as defined by local, regional, state, national and/or international governing entities.
