FTAG provides access to global firms involved in improving agricultural yields. Specifically, the fund consists of the following sub-industries: chemicals and fertilizers, seed manufacturers, irrigation equipment providers and farm machinery companies. The portfolio also includes farmland companies which is a unique feature in the global agriculture space. From a selection universe of eligible companies, the fund selects those that generate at least 10% of their revenue from the mentioned sub-industries and weights them according to market-cap. The index reconstitutes annually and rebalances quarterly. Prior to December 18, 2015, FTAG tracked a completely unrelated index of platinum miners under the fund name, First Trust ISE Global Platinum Index Fund (PLTM).
