FAR 4.1801 Definitions.
The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.
In plain English
This section defines two ownership terms used in the FAR: 'highest-level owner' and 'immediate owner.' It matters to contractors because these definitions determine how ownership and control must be identified and reported in certain filings.
Applies to: Offerors and their ownership structures
Key terms: Highest-level owner · Immediate owner · Control · Offeror

The text
As used in this part—
Highest-level owner means the entity that owns or controls an immediate owner of the offeror, or that owns or controls one or more entities that control an immediate owner of the offeror. No entity owns or exercises control of the highest level owner.
Immediate owner means an entity, other than the offeror, that has direct control of the offeror. Indicators of control include, but are not limited to, one or more of the following: ownership or interlocking management, identity of interests among family members, shared facilities and equipment, and the common use of employees.
