A more thorough explanation:

An officer's report is a formal presentation of facts or recommendations for action given by an officer to an organization or deliberative assembly. It can be either oral or written and relates to the officer's duties or a matter under their charge.

For example, a treasurer's report stating the amount of money in the bank is an officer's report. Another example is a report from a committee to a deliberative assembly on business referred to the committee or on a matter otherwise under its charge.

Officer's reports are important in keeping organizations and assemblies informed about the status of their affairs and making decisions based on the presented information.
