Brookfield Asset Management is a company that invests in alternative/Real Estate assets for institutional investors and family offices. Their investments include Private Equity, Infrastructure (harbors, train rails, highways), Real Estate (Canary Warf) and Renewables (Hydroelectric power plants, solar power plants).
These assets have "bond-like" pay-offs (like rents) with a higher yield than bonds themselves. Thus, they are attracting new investors. Their main competitive advantage is their size, as it enables them to compete for deals with less amount of players.
