The Fund invests in financial instruments that ProShare Advisors believes, in combination, should track the performance of the Index. The Index is constructed and maintained by Solactive AG. The Index is designed to measure the performance of publicly traded companies that principally sell online or through other non-store sales channels, such as through mobile or app purchases, rather than through bricks and mortar store locations. The Index includes U.S. and non-U.S. companies.
