Q. How can I find corporate affiliations?

Use the Directory of Corporate Affiliations, available through LexisNexis.  Search by name or ticker symbol for a company. Look for the "Parents & Subsidiaries" link in the company report to view a corporate hierarchy of affiliations.

Also consider using the following print sources, available in Pius Library:
