PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to replicate, before expenses, the performance of the Index.

The NYSE Arca U.S. Equity High Volatility Put Write Index is an index that measures the return of a hypothetical portfolio consisting of exchange traded put options which have been sold on each of 20 stocks and a cash position calculated as described herein under “Additional Information About the Index.” The 20 stocks on which options are sold (“written”) are those 20 stocks from a selection of the largest capitalized (over $5 billion in market capitalization) stocks which also have listed options and which have the highest volatility, as determined by the NYSE Arca, Inc., the Fund’s index provider (the “Index Provider”).

Each listed put option included in the Index is an “American-style” option (i.e., an option which can be exercised at the strike price at any time prior to its expiration) with a 60-day term. The strike price (i.e., the price at which a put option can be exercised) of each put option included in the Index must be as close as possible to 85% of the closing price of the option’s underlying stock price as of the beginning of each 60-day period. The listed put options included in the Index can be exercised at any time during prior to their expiration, but the Index will reflect the value of each such option throughout the 60-day period as if the option is not exercised until its expiration. Each such option will automatically be deemed exercised on its expiration date if its underlying stock price is below its strike price. If the stock underlying the put option closes below the option’s strike price, a cash settlement payment in an amount equal to the difference between the strike price and the closing price of the stock is deemed to be made and the Index value is correspondingly reduced. If the underlying stock does not close below its strike price, then the option expires worthless and the entire amount of the premium payment is retained within the Index.

The Fund will seek to track the performance of the Index by selling listed 60-day put options in proportion to their weightings in the Index. By selling an option, the Fund will receive premiums from the buyer of the option, which will increase the Fund’s return if the option is not exercised and thus expires worthless. However, if the option’s underlying stock declines below the strike price, the option will finish in-the-money and the Fund will be required to buy the underlying stock at the strike price, effectively paying the buyer the difference between the strike price and the closing price. Therefore, by writing a put option, the Fund is exposed to the amount by which the price of the underlying stock is less than the strike price. Accordingly, the potential return to the Fund is limited to the amount of option premiums it receives, while the Fund can potentially lose up to the entire strike price of each option it sells. Further, if the value of the stocks underlying the options sold by the Fund increases, the Fund’s returns will not increase accordingly.

As the seller of a listed put option, the Fund incurs an obligation to buy the underlying instrument from the purchaser of the option at the option’s strike price, upon exercise by the option purchaser. If a listed put option sold by the Fund is exercised prior to the end of a 60-day period, the Fund will buy the underlying stock at the time of exercise and at the strike price, and will hold the stock until the end of the 60-day period.

Each put option sold by the Fund will be covered through investments in three month Treasury bills at least equal to the Fund’s maximum liability under the option ( i.e ., the strike price).

Every 60 days, the options included within the Index are exercised or expire and new option positions are established, and the Fund will enter into new option positions accordingly and sell any underlying stocks it owns as a result of the Fund’s prior option positions having been exercised. This 60-day cycle likely will cause the Fund to have frequent and substantial portfolio turnover. If the Fund receives additional inflows (and issues more Shares accordingly in large numbers known as “Creation Units,” as further defined herein) during a 60-day period, the Fund will sell additional listed put options which will be exercised or expire at the end of such 60-day period. Conversely, if the Fund redeems Shares in Creation Unit size during a 60-day period, the Fund will terminate the appropriate portion of the options it has sold accordingly.

The Sub-Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

will either earmark or segregate sufficient liquid assets to cover its obligations under each option on an ongoing basis. Moreover, the options sold by the Fund may have imperfect correlation to the returns of their underlying stocks.

Equity Risk. The value of the options sold by the Fund is based on the value of the stocks underlying such options. Accordingly, the Fund is exposed to equity risk, which is the risk that the value of the stocks underlying options written by the Fund will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of such stock participate, or factors relating to specific companies. In such event, the value of the options sold by the Fund will likely decline. Additionally, if the value of the stocks underlying the options sold by the Fund increases, the Fund’s returns will not increase accordingly.

Implied Volatility Risk. When the Fund sells a listed put option, it gains the amount of the premium it receives, but also incurs a corresponding liability representing the value of the option it has sold (until the option is exercised and finishes in the money or expires worthless). The value of the options in which the Fund invests is partly based on the volatility used by market participants to price such options (i.e., implied volatility). Accordingly, increases in the implied volatility of such options will cause the value of such options to increase (even if the prices of the options’ underlying stocks do not change), which will result in a corresponding increase in the liabilities of the Fund under such options and thus decrease the Fund’s NAV. The Fund is therefore exposed to implied volatility risk before the options expire or are exercised. This is the risk that the value of the implied volatility of the options sold by the Fund will increase due to general market and economic conditions, perceptions regarding the industries in which the issuers of such stock participate, or factors relating to specific companies.

Tax Efficiency Risk. Unlike most exchange-traded funds, the Fund currently intends to effect redemptions primarily for cash, rather than primarily in-kind redemptions. As such, investments in Shares may be less tax-efficient than investments in conventional exchange-traded funds. Exchange-traded funds generally are able to make in-kind redemptions and avoid being taxed on gain on the distributed portfolio securities at the fund level. Because the Fund currently intends to effect redemptions primarily for cash, rather than in-kind distributions, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. If the Fund recognizes gain on these sales, this generally will cause the Fund to recognize gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were able to distribute portfolio securities in-kind. The Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than, if they had made an

investment in a different exchange-traded fund. In addition, as a result of the Fund selling options every 60 days to track the Index, it is expected that any distributions by the Fund will be taxable as ordinary income.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, an option sold by the Fund may be exercised prior to its expiration, which will result in the Fund buying the underlying stock at that time and holding the stock until the end of the 60-day period, but the Index will not reflect the early exercise of the option at that time. The Fund may also need to sell additional options (or terminate certain options it has already sold) prior to the end of the 60-day period to reflect Fund inflows or outflows; the costs of doing so may also contribute to tracking error. In addition, the Fund incurs a number of operating expenses not applicable to the Index and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses.

Portfolio Turnover Risk. The Fund will pay transaction costs, such as commissions or mark-ups in the bid/offer spread on an option position, when it writes options at the beginning of each 60 day period (or “turns over” its portfolio). A higher portfolio turnover (e.g., over 100% per year) will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example thereunder, may affect the Fund’s performance.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund. This risk may be particularly applicable to the Fund because the Fund will only sell options on 20 underlying stocks.

WHO SHOULD INVEST

The Fund is designed for investors who seek to obtain income through selling put options on select equity securities which the Index Provider determines to have the highest volatility. Because of the high volatility of the stocks underlying the put options sold by the Fund, it is possible that the value of such stocks will decline in sufficient magnitude to trigger the exercise of the put options and cause a loss which may outweigh the income from selling such put options. Accordingly, the Fund should be considered a speculative trading instrument and is not necessarily appropriate for investors who seek to avoid or minimize their exposure to stock market volatility. Investors should also recognize that the option positions in the Index are determined every 60 days and the Index, and thus the Fund, may thus experience substantial turnover in their option positions from one such 60-day period to the next. Accordingly, even investors who seek to obtain income from selling put options on volatile stocks generally should evaluate whether they wish to sell put options (indirectly through the Fund) on the particular stocks selected by the Index in any particular 60-day period. Unlike interests in many conventional mutual funds, the Shares are traded throughout the day on a national securities exchange, whereas mutual fund interests are typically only bought and sold at closing net asset values. The Shares have been designed to be tradable in the secondary market on a national securities exchange on an intra day basis, and to be created and redeemed principally for cash in Creation Units at each day’s next calculated NAV.

For example, suppose a stock “ABC” trades at $50 per share at the start of the 60 day period, and a listed put option with a term of 60 days was sold with a strike price of $42.50 per share for a premium of $2 per share:

Settlement at or above the strike price: If at the end of 60 days the ABC stock closed at or above the strike price of $42.50, then the option would expire worthless and the Index’s value would reflect the retention of the $2 per share premium. The Index’s value thus would be increased by $2 per share on the ABC option position.

Settlement below the strike price: If at the end of 60 days, ABC closed at $35, then the option would automatically be deemed exercised on its expiration date. The Index’s value would change as if the Index had been put (i.e., would buy) ABC at the strike price of $42.50 and sell ABC immediately at the closing price of $35. As a result, the Index’s value would be reduced by $7.50 per share. However, the Index’s value would also reflect the retention of the $2 per share premium, so the net loss to the Index’s value would be $5.50 per share on the ABC option position.

The Index’s value is equal to the value of the options positions comprising the Index plus a cash position. The cash position starts at a base of 1000. The cash position is increased by option premiums generated by the option positions comprising the Index and interest on the cash position at an annual rate equal to the three month Treasury-bill rate. The cash position is decreased by cash settlement on options which finish in the money (i.e., where the closing price of the underlying stock at the end of the 60 day period is below the strike price). The cash position is also decreased by a deemed cash distribution paid following each 60 day period, currently targeted at the rate of 1.5% of the value of the Index. However, if the option premiums generated during the period are less than 1.5%, the deemed distribution will be reduced by the amount of the shortfall.

The Fund will not invest in money market instruments as part of a temporary defensive strategy to protect against potential stock market declines. The Investment Adviser anticipates that it may take approximately three business days (i.e., each day the New York Stock Exchange (“NYSE”) is open) for additions and deletions to the Index to be reflected in the portfolio composition of the Fund.

The Fund may borrow money from a bank up to a limit of 10% of the value of its assets, but only for temporary or emergency purposes.

The policies described herein constitute non fundamental policies that may be changed by the Board of Trustees of the Trust without shareholder approval. Certain fundamental policies of the Fund are set forth in the Statement of Additional Information under “Investment Restrictions.”

ADDITIONAL RISK CONSIDERATIONS

In addition to the risks described previously, there are certain other risks related to investing in the Fund.

Trading Issues. Trading in Shares on the ARCA may be halted due to market conditions or for reasons that, in the view of the ARCA, make trading in Shares inadvisable. In addition, trading in Shares on the ARCA is subject to trading halts caused by extraordinary market volatility pursuant to the ARCA “circuit breaker” rules. There can be no assurance that the requirements of the ARCA necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Fluctuation of Net Asset Value. The NAV of the Fund’s Shares will generally fluctuate with changes in the market

value of the Fund’s holdings. The market prices of the Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for the Shares on the ARCA. The Sub-Adviser cannot predict whether the Shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for the Shares will be closely related to, but not identical to, the same forces influencing the prices of the stocks of the Index trading individually or in the aggregate at any point in time.

However, given that the Shares can be purchased and redeemed in Creation Units (unlike shares of many closed end funds, which frequently trade at appreciable discounts from, and sometimes premiums to, their NAV), the Sub-Adviser believes that large discounts or premiums to the NAV of the Shares should not be sustained.

These risks are described further in the Statement of Additional Information.

to compensate the Investment Adviser for providing services for the Fund.

Sub-Adviser

Rich Investment Solutions, LLC acts as the Fund’s sub-adviser pursuant to a sub-advisory agreement with the Investment Adviser (the “Sub-Advisory Agreement”). The Sub-Adviser is a newly formed registered investment adviser, and has its principal office located at 845 Third Avenue, 6th Floor, New York, NY 10022.

Pursuant to the Sub-Advisory Agreement, the Adviser pays the Sub-Adviser on a monthly basis a portion of the advisory fees it receives from the Fund, on an annual rate of 0.80% of average net assets.

Approval of Advisory Agreement and Sub-Advisory Agreement

A discussion regarding the basis for the Board of Trustees’ approval of the Advisory Agreement and Sub-Advisory Agreement will be available in the Fund’s semi-annual report to shareholders for the period ended May 31, 2013.

nature of fair market value pricing, it is possible that the value determined for a particular asset may be materially different from the value realized upon such asset’s sale.

Creation Units

Investors such as market makers, large investors and institutions who wish to deal in Creation Units directly with the Fund must have entered into an authorized participant agreement with the distributor and the transfer agent, or purchase through a dealer that has entered into such an agreement. Set forth below is a brief description of the procedures applicable to purchase and redemption of Creation Units. For more detailed information, see “Creation and Redemption of Creation Unit Aggregations” in the Statement of Additional Information.

(normally 4:00 p.m. Eastern time) in order to receive that day’s closing NAV per Share.

A fixed redemption transaction fee of $500 per transaction (the “Redemption Transaction Fee”) is applicable to each redemption transaction regardless of the number of Creation Units redeemed in the transaction. See “Creation and Redemption of Creation Unit Aggregations” in the Statement of Additional Information.

Distributions

Dividends and Capital Gains . Fund shareholders are entitled to their share of the Fund’s income and net realized gains on its investments. The Fund pays out substantially all of its net earnings to its shareholders as “distributions.”

The Fund typically earns income dividends from stocks and interest from debt securities. These amounts, net of expenses, are passed along to Fund shareholders as “income dividend distributions.” The Fund realizes capital gains from writing options and capital gains or losses whenever it sells securities. Any net long term capital gains (which are not anticipated) are distributed to shareholders as “capital gain distributions.”

Income dividends, if any, and any net short-term capital gains are distributed to shareholders following each 60 day period. Any other net income or gains are distributed at least annually. Dividends may be declared and paid more frequently to improve Index tracking or to comply with the distribution requirements of the Internal Revenue Code. In addition, the Fund intends to distribute, at the end of each 60-day period out of net investment income and/or net short-term capital gains, an amount of cash equal to 1.5% of the Fund’s net assets at the end of such 60-day period. If the Fund’s net investment income and net short-term capital gains are insufficient to support a 1.5% distribution in any 60-day period, the distribution will be reduced by the amount of the shortfall. While the Fund only intends to make such distributions out of net investment income and/or short-term capital gains, it is possible that in certain circumstances, a portion of a distribution may result in a return of capital (which is a return of the shareholder’s investment in the Fund). Section 19(a) of the Investment Company Act of 1940, as amended (the “1940 Act”), and Rule 19a-1 thereunder require the Fund to provide a written statement accompanying any such distribution that adequately discloses its source or sources to the extent the source includes something other than net investment income. Thus, if the source of the dividend or other distribution were the original capital contribution of the shareholder, and the payment amounted to a return of capital, the Fund would be required to provide written disclosure to that effect. Nevertheless, persons who periodically receive the payment of a dividend or other distribution may be under the impression that they are receiving net profits when they are not. Shareholders should read any written disclosure provided pursuant to Section 19(a) and Rule 19-1 carefully, and should not assume that the source of any distribution from the Fund is net profit.

Distributions in cash may be reinvested automatically in additional whole Shares only if the broker through which the Shares were purchased makes such option available.

FEDERAL INCOME TAXATION

As with any investment, you should consider how your investment in Shares will be taxed. The tax information in this Prospectus is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares.

Unless your investment in the Shares is made through a tax exempt entity or tax deferred retirement account, such as an IRA plan, you need to be aware of the possible tax consequences when:

Dividends and interest from non-U.S. investments received by the Fund may give rise to withholding and other taxes imposed by foreign countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes.

The Fund generally would be required to withhold a percentage of your distributions and proceeds if you have not provided a taxpayer identification number (generally your social security number) or otherwise provide proof of an applicable exemption from backup withholding. The backup withholding rate for an individual is currently 28%.

Taxes on Exchange Listed Shares Sales

Currently, any capital gain or loss realized upon a sale of Shares is generally treated as long term capital gain or loss if the Shares have been held for more than one year and as short term capital gain or loss if the Shares have been held for one year or less. The ability to deduct capital losses may be limited.

OTHER INFORMATION
