|Renaissance IPO ETF|
|The investment seeks to replicate as closely as possible, before fees and expenses, the price and yield performance of the Renaissance IPO Index (the "index").
The fund normally invests at least 80% of its total assets in securities that comprise the fund's benchmark index, the Renaissance IPO Index. The remaining 20% may be used to purchase securities not in the index that are an appropriate substitute for certain securities in the index in order to track the index. The index is comprised of common stocks, American Depositary Receipts ("ADRs"), real estate investment trusts ("REITS") and master limited partnerships ("MLPs"). The fund is non-diversified.|
