Refer to the Fund’s Schedule of Investments for a listing of the securities by type and sector. The Fund held no Level 3 securities at any time during the six months ended June 30, 2026.

Security Transactions and Income

Security transactions are accounted for on the trade date. The cost of securities sold is determined generally on a specific identification basis. Realized gains and losses from security transactions are determined on the basis of identified cost for book and tax purposes. Dividends are recorded on the ex-dividend date. Interest income is recorded on an accrual basis. Discounts and premiums on securities purchased are amortized or accreted using the effective interest method. Withholding taxes on foreign dividends have been provided for in accordance with the Fund’s understanding of the applicable country’s tax rules.

Cash and Cash Equivalents

Cash and cash equivalents, if any, consist of overnight deposits with the custodian bank which earn interest at the current market rate.

Accounting Estimates

In preparing financial statements in conformity with GAAP, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the

financial statements, as well as the reported amounts of investment income and expenses during the reporting period. Actual results could differ from those estimates.

Federal Income Taxes

The Fund has complied and intends to continue to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to its shareholders. The Fund also intends to distribute sufficient net investment income and net capital gains, if any, so that it will not be subject to excise tax on undistributed income and gains. Therefore, no federal income tax or excise provision is required.

Management has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken in the Fund’s tax returns. The Fund has no examinations in progress and management is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. Interest and penalties, if any, associated with any federal or state income tax obligations are recorded as income tax expense as incurred.

Reclassification of Capital Accounts

GAAP requires that certain components of net assets relating to permanent differences be reclassified between financial and tax reporting. During the six months ended June 30, 2026, there were no such reclassifications.

Dividends and Distributions

Dividends from net investment income, if any, are declared and paid at least quarterly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders annually. The Fund may also pay a special distribution at the end of a calendar year to comply with federal tax requirements. All distributions are recorded on the ex-dividend date.

Creation Units

The Fund issues and redeems shares to certain institutional investors (typically market makers or other broker-dealers) only in blocks of at least 10,000 shares known as “Creation Units.” Purchasers of Creation Units (“Authorized Participants”) will be required to pay to Citibank, N.A. (the “Custodian”) a fixed transaction fee (“Creation Transaction Fee”) in connection with creation orders that is intended to offset the transfer and other transaction

costs associated with the issuance of Creation Units. The standard Creation Transaction Fee will be the same regardless of the number of Creation Units purchased by an investor on the applicable Business Day. The Creation Transaction Fee charged by the Custodian for each creation order is $250. Authorized Participants wishing to redeem shares will be required to pay to the Custodian a fixed transaction fee (“Redemption Transaction Fee”) to offset the transfer and other transaction costs associated with the redemption of Creation Units. The standard Redemption Transaction Fee will be the same regardless of the number of Creation Units redeemed by an investor on the applicable Business Day. The Redemption Transaction Fee charged by the Custodian for each redemption order is $250.

Except when aggregated in Creation Units, shares are not redeemable securities. Shares of the Fund may only be purchased or redeemed by Authorized Participants. An Authorized Participant is either (i) a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the National Securities Clearing Corporation or (ii) a Depository Trust Company (“DTC”) participant and, in each case, must have executed an agreement with the Fund’s principal underwriter (the “Distributor”) with respect to creations and redemptions of Creation Units (“Participation Agreement”). Most retail investors will not qualify as Authorized Participants or have the resources to buy and sell whole Creation Units. Therefore, they will be unable to purchase or redeem the shares directly from the Fund. Rather, most retail investors will purchase shares in the secondary market with the assistance of a broker and will be subject to customary brokerage commissions or fees. The following table discloses the Creation Unit breakdown based on the NAV as of June 30, 2026:

To the extent contemplated by a participant agreement, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the shares comprising a Creation Unit to be redeemed to the Distributor, on behalf of the Fund, by the time as set forth in a participant agreement, the Distributor may nonetheless accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible, which undertaking shall be secured by the Authorized Participant’s delivery and maintenance of collateral equal to a percentage of the value of the missing shares as specified in the participant agreement. A participant agreement may permit the Fund to use such collateral

to purchase the missing shares, and could subject an Authorized Participant to liability for any shortfall between the cost of the Fund acquiring such shares and the value of the collateral. Amounts are disclosed as Segregated Cash Balance from Authorized Participants for Deposit Securities and Collateral Payable upon Return of Deposit Securities on the Statement of Assets and Liabilities, when applicable.

Officers and Trustees Indemnification

Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, in the normal course of business, the Fund enters into contracts with its vendors and others that provide for general indemnifications. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund. However, based on experience, the Fund expects that the risk of loss will be remote.

Derivatives

The Fund derivative investments may include, among other instruments: (i) options; (ii) volatility-linked ETFs; and (iii) volatility-linked exchange-traded notes (“ETNs”). These derivatives will be used to hedge risks associated with the Fund’s other portfolio investments. The Fund may also use derivatives to create income by writing covered call options. In writing covered calls, the Fund sells an option on a security that the Fund owns in exchange for a premium (i.e., income). FLEX Options, whose customized exercise prices and expiration dates allow the Fund to more precisely implement its investment strategy than through what could be achieved through the use of standardized option contracts. Options are subject to equity price risk that arises from the possibility that equity security prices will fluctuate affecting the value of the options. As a result of the Funds’ use of derivatives, each Fund may have economic leverage, which means the sum of the Fund’s investment exposures through its use of derivatives may exceed the amount of assets invested in the Fund, although these exposures may vary over time. The Fund has adopted policies and procedures pursuant to Rule 18f-4 of the Act 1940 relating to the use of derivatives.

The table below discloses both gross information and net information about instruments and transactions eligible for offset in the Statement of Assets and Liabilities and instruments and transactions that are subject to an agreement similar to a master netting agreement held at counterparties.

Liabilities:

*  The collateral amount shown here is limited to the liability balance. Total collateral balances are shown on the Statement of Assets and Liabilities

Actual cash amounts required at each counterparty are based on the notional amounts or the number of contracts outstanding and may exceed the cash presented in the collateral tables. The master netting agreements allow the clearing brokers to net any collateral held in or on behalf of the Fund or liabilities or payment obligations of the clearing brokers to the Fund against any liabilities or payment obligations of the Fund to the clearing brokers. The Fund may be required to deposit financial collateral (including cash collateral) at the clearing

brokers and counterparties to continually meet the original and maintenance requirements established by the clearing brokers and counter parties. Such requirements are specific to the respective clearing broker or counterparty.
