The Dow Jones Brookfield Communications Infrastructure Index is a global index that is designed to measure the performance of pure-play infrastructure companies in the communications sector. To be included in the index, a company must derive at least 70% of cash flows from infrastructure lines of business and at least 50% of cash flows from the development, lease, concession, or management of broadcast/mobile towers, satellites, and fibre optic/copper (excludes telecom services) cable. The index is a subset of the Dow Jones Brookfield Global Infrastructure Index.
