The department may have access to information, and in considering an application it would certainly use information to which it already has access. It's helpful to the department in the process, so that's the reason for the five factors being together and the terminology “if any”. It's so that the applicant provides information if they've been able to obtain it to support the decision-making process. In asking the applicant to provide it if they have it, it's to help access information that the department might not have access to.
