UFO is the first global aerospace & defense fund. The companies included in this fund span several industries, including (a) satellite-based consumer products and services, (b) rocket and satellite manufacturing, deployment and maintenance, (c) space technology hardware, (d) ground equipment manufacturing, and (e) space-based imagery and intelligence services. The fund divides its constituents into two tranches. The first tranche is comprised of non-diversified companies that derive at least 50% (but typically 100%) of their revenues from space-related activities. The second tranche is comprised of diversified companies that play a significant role in the production of space technology and equipment. The non-diversified tranche is then given 80% of the weight of the Underlying Index and the diversified tranche is given 20% of the weight. The index is reconstituted and rebalanced semi-annually.
