Investment objective & strategy

As of Oct. 31, 2025 · prospectus

Objective. The Wayfinder Dynamic U.S. Interest Rate ETF (for this section only, the Fund) seeks to provide investment results that, before fees and expenses, equal or exceed the performance of an investment that tracks the rolling 0-12 month segment of the United States Treasury Bill market.

Strategy. The Wayfinder Dynamic U.S. Interest Rate ETF is an actively managed exchange-traded fund (ETF) whose investment objective seeks to provide investment results that, before fees and expenses, equal or exceed the performance of an investment that tracks the rolling 0-12 month segment of the United States Treasury Bill market. To do so, the Fund will primarily utilize a combination of long and short exchange-listed options (including FLEX Options, that is, customizable options) commonly called a box spread (Box Spread). The Funds investment in options differs from a direct investment in the United States Treasury Bill market.

To do so, the Fund will primarily utilize a combination of long and short exchange-listed options (including FLEX Options, that is, customizable options) commonly called a box spread (Box Spread). The Funds investment in options differs from a direct investment in the United States Treasury Bill market. In general, an option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a call) or sell (a put) an asset at an agreed-upon price (strike price) at or prior to a specified date (expiration date) in the near future. In the case of a call option, the purchaser has the right to buy the particular asset and the seller of a call option has the obligation to deliver the particular asset at the strike price. In the case of a put option, the purchaser has the right to sell the particular asset and the seller of a put option has the obligation to purchase the particular asset at the strike price. A Box Spread is an offsetting set of options that have risk and return characteristics similar to cash equivalents and generally consists of four options. Two options create a synthetic long position and the other two options create an offsetting synthetic short position. All four options relate to a single equity security or an equity index and have the same expiration date. The selection of a single equity security or an equity index depends on market conditions and variables that may include but are not limited to liquidity, open interest, supply/demand, and relative prices. The synthetic long position consists of buying a call option and selling a put option on the same security or index where the call option and put option share the same strike and expiration date (a Synthetic Long). When purchasing a Box Spread, the Synthetic Long will have a strike price that is less than the strike price for the synthetic short position. The synthetic short consists of buying a put option and selling a call option on the same security or index with the same expiration date as the Synthetic Long but using a different strike price (a Synthetic Short). The difference between the strike prices of the Synthetic Long and the Synthetic Short will determine the expiration value (or value at maturity) of the Box Spread, which should be equivalent to a time value of return for debt instruments with a duration that is equal to the duration of the Box Spread. The Funds investment adviser, Gladius, will invest the Funds assets in a series of Box Spreads with various expiration dates. The quantity and expiration dates of the Box Spreads held by the Fund will be based on several factors, including the Funds asset size, the effective yield for various Box Spread expiration dates available in the marketplace, and Gladius view of future interest rates. The Fund will only invest in a Box Spread when it expects a positive pre-tax return (after considering all costs to the Fund). Based upon historical examples of Box Spreads actually traded in the marketplace, Gladius expects that there will be market participants willing to sell Box Spreads to the Fund in sufficient quantities to satisfy the objective of the Fund. The Fund anticipates a typical maturity of up to one-year. For cash management purposes, the Fund may use the invest directly or through derivatives, including listed options, index options, or FLEX Options with customized terms. The Funds allocations supporting its stated investment objectives are dynamic and dependent on prevailing market conditions. Such allocations may range from 0% to 99% of net assets, with the remainder invested in instruments utilized for cash management purposes. The Fund expects to terminate some or all of the Box Spreads prior to their respective expiration dates, when Gladius believes it is advantageous for the Fund to do so. This may include but is not limited to instances where the theoretical or modeled option price is greater than current market prices and when changes occur in supply/demand or in the relative pricing value of the options. Upon expiration or sale of any Box Spread, Gladius may seek to purchase additional Box Spreads at an effective yield and expiration date that offers favorable risk and reward characteristics under current market conditions. The Fund may also invest in cash, cash equivalents, money market funds, treasury bills, swaps, or futures. The Funds strategy is expected to result in high portfolio turnover. The return that the Fund expects to earn from Box Spreads will fluctuate but remain consistent with the market rate for similar short-term interest rate sensitive securities as reflected by the Federal Funds Futures market. The Federal Funds Futures market is a marketplace for trading financial contracts that are based on the average monthly federal funds rate, which is the overnight interest rate at which banks lend reserves to one another. This market allows participants to hedge against or speculate on changes in short-term interest rates, including those influenced by the Federal Reserves monetary policy. The Fund will engage in active and frequent trading of portfolio securities to achieve its investment objective. In order to achieve its objective, the Fund will typically purchase a new Box Spread at the time (or as soon as reasonably practicable thereafter, subject to market conditions and the availability of trading venues) any existing Box Spread expires or is terminated or when Gladius believes purchasing a new Box Spread would offer a favorable investment opportunity. The Fund may also sell or roll any Box Spread at any time. When rolling a Box Spread, the Fund enters into a trade where it simultaneously closes on each component of an existing Box Spread while opening a new Box Spread position. The Fund may also sell Box Spreads that utilize the same or different reference assets, strike prices, and expiration dates as Box Spreads owned by the Fund. When selling or rolling a Box Spread, the Fund may incur additional transaction costs than if it waited until such Box Spread expired. The Fund may also utilize conversions and reversals. A conversion (reversal) order is an order involving the purchase (sale) of a put option and the sale (purchase) of a call option in equivalent units with the same strike price and expiration in the same underlying asset, and the purchase (sale) of the related instrument. While investing in a particular market sector is not a principal investment strategy of the Fund, its portfolio may be significantly invested in a sector as a result of the portfolio management decisions made pursuant to its principal investment strategy. Under normal market conditions, the Fund generally invests substantially all, but at least 80% of its net assets in U.S. securities and/or derivatives. For purposes of this policy, investments that are considered tied economically to the United States include, but are not limited to: securities of issuers that are organized or incorporated under the laws of the United States; issuers whose principal place of business is in the United States; issuers that derive a majority of their revenues from business activities within the United States; U.S. Treasury securities and U.S. Treasury futures contracts; and other financial instruments that provide exposure to U.S. equity or fixed income markets, including derivatives based on U.S. indices or securities. The Fund intends to elect to be, and intends to qualify each year for treatment as, a regulated investment company (RIC) under Subchapter M of Subtitle A, Chapter 1, of the Internal Revenue Code of 1986, as amended (the Code). The Fund expects to make sufficient distributions as required by the Code so that it is not subject to net U.S., federal income tax. An important feature of the Box Spread is that it aims to eliminate risk tied to price movements in the underlying securities referenced in the options within the Box Spread. This is due to the offsetting synthetic long and short linear exposures used in the construction, which net against each other. The only residual market exposure is to short-term interest rates. Buying (or selling) a Box Spread has economic similarities to buying (or selling) a zero-coupon bond. A zero-coupon bond does not pay periodic coupons, but the bond trades at a discount to its face value. The maturity value of a zero-coupon bond is comparable to the difference in the strike prices of the Box Spread. The maturity date of a zero-coupon bond is comparable to the expiration date of the options comprising the Box Spread. When constructing a Box Spread, the strike price of the Synthetic Long will be at a lower strike price than the strike price of the Synthetic Short. When buying or selling a Box Spread, the buyer or seller generally expects the price of the Box Spread to be less than the difference in the strike prices of the Box Spread. A buyer or seller of a Box Spread will earn a profit or loss equal to the difference between the beginning price (price paid to buy or received if sold) and the ending price (expiration value or closing trade price). If the Fund holds the Box Spread until expiration, then its profit or loss will be determined by the difference between the price it paid to buy the Box Spread (or received in the case of selling the Box Spread) and the value of the Box Spread upon expiration. As an example, a typical Box Spread could include the simultaneous purchase of a call option and sale of a put option (i.e. Synthetic Long) with a strike of $1,000 on the SPDR S&P 500 ETF Trust (SPY) together with the sale of a call option and purchase of a put option (i.e. Synthetic Short) with a strike of $2,000 on the SPY where all four of these options share the same expiration date. The expiration or maturity value would be the difference in the strikes or $1,000 in this case. The expected profit earned would equal the difference between the price paid for this Box Spread and its expiration value of $1,000 minus any transaction costs associated with the options trades. The effective yield on each Box Spread is determined by annualizing the profit over the price paid.
