Beyond CapEx and OpEx considerations, the ability to extract cash to offshore (via loans from offshore companies to entities offshore) allows both tax avoidance (legally) and transfer of wealth to executives (legally, since ownership of the various companies is diluted with other executive "co-conspirators"). I know this because I worked at companies where they kept reselling and reselling the skyscrapers over and over again - so they could keep maximizing their ability to make themselves richer while avoiding taxes.
