**Significant Accounting Policies.** The Schedule of Investments have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) and the Funds are each considered an investment company under U.S. GAAP and follow the accounting and reporting guidance applicable to investment companies. The following summarizes the significant accounting policies of the Funds:

**Funds Valuation.** The Trust's Board of Trustees ("Board" or "Trustees"), including a majority of the Trustees who are not "interested persons" of the Trust, have designated the Adviser to perform fair valuation determinations related to all Fund investments under the oversight of the Board. As "valuation designee" the Adviser has adopted procedures to guide the determination of the net asset value ("NAV") on any day on which a Fund's NAVs are determined. The valuation of the Funds' investments is in accordance with these procedures.

Fund securities that are traded on U.S. securities exchanges, except option securities, are valued at the official closing price, which is the last current reported sales price on its principal exchange at the time each Fund determines its NAV. Securities traded in the over-the-counter market and quoted on The NASDAQ Stock Market® are valued at the NASDAQ® Official Closing Price, as determined by NASDAQ®, or lacking a NASDAQ® Official Closing Price, the last current reported sale price on NASDAQ® at the time a Fund determines its NAV. When a last sale or closing price is not available, equity securities, other than option securities, that are traded on a U.S. securities exchange and other equity securities traded in the over-the-counter market are valued at the mean between the most recent bid and asked quotations on its principal exchange in accordance with guidelines adopted by the Board. Each option security traded on a U.S. securities exchange is valued at the mid-point of the consolidated bid/ask quote for the option security, also in accordance with guidelines adopted by the Board. Each over-the-counter option that is not traded through the Options Clearing Corporation is valued either by an independent pricing agent approved by the Board or based on a quotation provided by the counterparty to such option under the ultimate supervision of the Board.

Trading on European and Far Eastern exchanges and over-the-counter markets is typically completed at various times before the close of business on each day on which the New York Stock Exchange ("NYSE") is open. Securities that are principally traded in foreign markets are valued as of the last reported sale price at the time the respective Fund determines its NAV, or when reliable market prices or quotations are not readily available, at the mean between the most recent bid and asked quotations as of the close of the appropriate exchange or other designated time. Trading of foreign securities may not take place on every NYSE business day. In addition, trading may take place in various foreign markets on Saturdays or on other days when the NYSE is not open and on which the respective Fund's NAV is not calculated.

FLexible EXchange® Options ("FLEX Options") listed on an exchange will typically be valued at a model-based price at the official close of that exchange's trading day. However, when a Fund's option has a same-day market trade price, this same-day market trade price will be used for FLEX Option values instead of the exchange's model-based price. If the pricing vendor is not available to provide a model price for that day, the value of a FLEX Option will be determined by the Valuation Designee (as defined in Rule 2a-5) in accordance with the Pricing and Valuation Policy and Fair Value Procedures. The FLEX Options held by the Funds will be exercisable at the strike price only on their expiration date.

If the valuation designee determines that the valuation of a security in accordance with the methods described above is not reflective of a fair value for such security, the security is valued at a fair value by the valuation designee.

Each Fund also may use fair value pricing, pursuant to guidelines adopted by the Adviser, if trading in the security is halted or if the value of a security it holds is materially affected by events occurring before the Fund's pricing time but after the close of the primary market or exchange on which the security is listed. Those procedures may utilize valuations furnished by pricing services approved by the Adviser, which may be based on market transactions for comparable securities and various relationships between securities that are generally recognized by institutional traders, a computerized matrix system, or appraisals derived from information concerning the securities or similar securities received from recognized dealers in those securities.

When fair value pricing of securities is employed, the prices of securities used by a Fund to calculate its NAV may differ from market quotations or official closing prices. There can be no assurance that a Fund could purchase or sell a portfolio security at the price used to calculate a Fund's NAV.

**Foreign Currency Translation.** Values of investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using a rate quoted by a major bank or dealer in the particular currency market, as reported by a recognized quotation dissemination service.

**Note 2 – Fair Value Measurements**

Various inputs are used to determine the value of the Funds' investments. These inputs are categorized into three broad levels as follows:

● Level 1 – Prices are determined using inputs from unadjusted quoted prices from active markets (including securities actively traded on a securities exchange) for identical assets.

● Level 2 – Prices are determined using significant observable market inputs other than unadjusted quoted prices, including quoted prices of similar securities, fair value adjustments to quoted foreign securities, interest rates, credit risk, prepayment speeds, and other relevant data.

● Level 3 – Prices reflect unobservable market inputs (including the Fund's own judgments about assumptions market participants would use in determining fair value) when observable inputs are unavailable.

Debt securities are valued based upon evaluated prices received from an independent pricing service or from a dealer or broker who makes markets in such securities. Pricing services utilize various observable market data and as such, debt securities are generally categorized as Level 2. The levels are not necessarily an indication of the risk or liquidity of the Fund's investments.

The following is a summary of the inputs used in valuing the Funds' holdings at fair value:
