The term “parent company” is used in 21 CFR 1.232(a)(4) and is intended to have the meaning it
has in the corporate context. If a facility is part of a company that is owned by another
corporation, then the corporation would be the parent company. For example, if a facility is
owned by Company X, and Company X is a subsidiary of Corporation Y, then the owner of the
facility is Company X and the parent company is Corporation Y.
