Other companies were sometimes absorbed into these government-owned corporations, as well as other companies, such as National Power Corporation (Napocor) and the Philippine National Railways, which in their own right are monopolies (exceptions are Meralco and the Manila Hotel).
Ostale tvrtke su ponekad spojene s ovim kompanijama u vlasništvu države, kao i s drugim kompanijama, npr. s Napocor i Philippine National Railways, koje na svom području djelatnosti imaju monopol (izuzetek su Meralco i Manila Hotel).
