The Globe and Mail reports in its Thursday edition the success of Brookfield Asset Management's transformation in the late-1990s from the Edper/Brascan empire has not gone unnoticed at Enbridge. Guest columnist Gabriel Lowenberg writes Brookfield simplified its corporate structure into sole-purpose public entities, such as Brookfield Infrastructure Partners and Brookfield Energy Partners. Enbridge has three main subsidiaries -- Enbridge Energy Partners, Enbridge Income Fund Holdings and Enbridge Energy Management LLC. Last December, Enbridge Inc. management declared its intent to roll more assets into the sole-purpose companies controlled by these entities. Henceforth, the public subsidiaries will issue most of the equity and debt to finance the future capital-expansion projects that they own. Over time, Enbridge Inc. will thus have to issue less equity and debt, and will consequently enjoy more organic earnings growth. Enbridge aims to roll more of its $53-billion in property, plant and equipment, or PPE, into the respective Canadian and U.S. subsidiaries. The related entities will pay more management fees to the parent, so Enbridge Inc. will earn a higher return on the lower capital employed.
