The investment seeks investment results that replicate as closely as possible, before fees and expenses, the performance of the S-Network Sector Dividend Dogs Index. The underlying index is a rules-based index intended to give investors a means of tracking the overall performance of the highest dividend paying stocks in the S&P 500 on a sector-by-sector basis. The fund generally will invest in all of the securities that comprise the underlying index in proportion to their weightings in the underlying index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the underlying index in those weightings.
