Definition

A reporting period is the date or interval represented by the information in a filing. For Form 13F, it is the calendar quarter-end date for the disclosed holdings. It is different from the later filing date, acceptance timestamp, retrieval date, and AUMSearch processing date.

Why this distinction matters

Treating filed date as the holdings date makes time-series analysis inaccurate. A 13F position reported for quarter-end can be published weeks later, and the manager may have changed the position before public release.
