Determining the original parent company requires identifying the entity that first established or acquired a controlling interest in the subsidiary in question. This initial parent company would have provided strategic direction, resources, and management oversight. The nature and timing of any transitions in ownership might be documented in historical business records, shareholder agreements, or legal filings related to the subsidiary’s inception or acquisition. Access to such documents, or the company’s archival records, would clarify whether this parent company still holds that role or if ownership has changed hands over time.
