The Funds target both operating assets and greenfield investment opportunities with the objective of investing in core energy, transportation and social infrastructure assets.

formed under the laws of the Province of Québec that acquires and holds investments in infrastructure assets located in Canada. The Canadian Manager serves as the investment adviser to the Canadian Fund and to certain other "feeder" funds that invest in the US and/or in the Canadian Fund.

The investments made by the US Country Funds are only made in assets located within the United States. The investments made by the Canadian Fund are only made in assets located within Canada. Pursuant to the terms of management services agreements, the respective General Partner of each Advised Fund will delegate to the Canadian Manager substantially all of its management rights and certain obligations under its limited partnership agreement.
