NOTES TO FINANCIAL STATEMENTS

MAY 31, 2021 (UNAUDITED)

NOTE 1.  ORGANIZATION

The One Rock Fund (the "Fund") is a non-diversified series of the MSS Series Trust (the "Trust") and commenced operations on March 6, 2020.  The Trust is an open-end investment company registered under the Investment Company Act of 1940, as amended (the "1940 Act"), established under the laws of Ohio by an Agreement and Declaration of Trust dated June 20, 2006 (the "Trust Agreement"). The Trust Agreement permits the Board of Trustees (the "Board" or "Trustees") to authorize and issue an unlimited number of shares, without par value, of beneficial interest of each separate series. There are currently seven separate series offered by the Trust. The investment adviser to the Fund is Wrona Investment Management, LLC (the "Adviser").

The Fund’s investment objective is to seek capital appreciation.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of the Fund’s significant accounting policies. These policies are in conformity with accounting principles generally accepted in the United States of America (“GAAP”).

As an investment company, the Fund follows the investment company accounting and reporting requirements of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, “Financial Services – Investment Companies” including FASB Accounting Standards Update (“ASU”) 2013-08.

SECURITY VALUATIONS: All investments in securities are recorded at their estimated fair value, as described in Note 3.

SECURITY TRANSACTION TIMING: For financial reporting purposes, investment transactions are accounted for on the trade date on the last business day of the reporting period.  Dividend income and distributions to shareholders are recognized on the ex-dividend date.  Non-cash dividend income is recorded at fair market value of the securities received.  Interest income is recognized on an accrual basis.  The Fund uses the specific identification method in computing gain or loss on sale of investment securities.  Discounts and premiums on securities purchased are accreted or amortized over the life of the respective securities using the effective interest method.  Withholding taxes on foreign dividends have been provided for in accordance with the Fund's understanding of the appropriate country’s rules and tax rates.

FEDERAL INCOME TAXES: The Fund makes no provision for federal income or excise tax. The Fund intends to qualify each year as a “regulated investment company” (“RIC”) under subchapter M of the Internal Revenue Code of 1986, as amended, by complying with the requirements applicable to RICs and by distributing substantially all of their taxable income. The Fund also intends to distribute sufficient net investment income and net capital gains, if any, so that they will not be subject to excise tax on undistributed income and gains. If the required amount of net investment income or gains

Semi-Annual Report | 11

ONE ROCK FUND

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

MAY 31, 2021 (UNAUDITED)

is not distributed, the Fund could incur a tax expense. Therefore, no federal income tax or excise provision is required.

The Fund recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained, assuming examination by tax authorities. Management has analyzed the Fund’s tax positions and concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions expected to be taken in the Fund’s 2020 tax return. The Fund identifies its major tax jurisdiction as U.S. federal, and the Fund is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

The Fund recognizes interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations. During the six months ended May 31, 2021, the Fund did not incur any interest or penalties.

SHARE VALUATION: The Fund’s NAV is calculated once daily at the close of regular trading hours on the New York Stock Exchange (the "NYSE") (generally 4:00 p.m. Eastern Time) on each day the NYSE is open. The NAV is determined by totaling the value of all portfolio securities, cash and other assets held by the Fund, and subtracting from that total all liabilities, including accrued expenses.  The total net assets are divided by the total number of shares outstanding for the Fund to determine the NAV.

DISTRIBUTIONS TO SHAREHOLDERS: The Fund typically distributes substantially all of its net investment income and realized gains in the form of dividends and taxable capital gains to its shareholders. The Fund intends to distribute dividends and capital gains at least annually.  Distributions to shareholders, which are determined in accordance with income tax regulations, are recorded on the ex-dividend date.  The treatment for financial reporting purposes of distributions made to shareholders during the year from net investment income or net realized capital gains may differ from their ultimate treatment for federal income taxes purposes. These differences are caused primarily by differences in the timing of the recognition of certain components of income, expense or realized capital gain for federal income tax purposes. Where such differences are permanent in nature, they are reclassified in the components of the net assets based on their ultimate characterization for federal income tax purposes.  Any such reclassifications will have no effect on net assets, results of operations or NAV per share of the Fund.

NON-DIVERSIFICATION RISK: As a non-diversified fund, the Fund may invest more than 5% of its total assets in the securities of one or more issuers.  The Fund's performance may be more sensitive to any single economic, business, political or regulatory occurrence than the value of shares of a diversified investment company.  The Fund's performance may be affected disproportionately by the performance of relatively few stocks.  In addition, the volatility of the Fund may be greater than the overall volatility of the market.

Semi-Annual Report | 12

ONE ROCK FUND

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

MAY 31, 2021 (UNAUDITED)

EXPENSES:  Expenses incurred by the Trust that do not relate to a specific fund of the Trust will be allocated to the individual funds based on each fund’s relative net assets or another appropriate basis (as determined by the Trustees).

USE OF ESTIMATES: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS: The Fund maintains its cash in an account at a custodian bank which, at times, may exceed federally insured limits. The Fund has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk on its cash deposits.

NOTE 3.  SECURITY VALUATIONS  

Processes and Structure

The Board has adopted guidelines for valuing securities including circumstances in which market quotes are not readily available and has delegated to the Adviser the responsibility for determining fair value prices, subject to oversight by the Board.

Fair Value Pricing Policy

The Board has adopted guidelines for fair value pricing and has delegated to the Adviser the responsibility for determining fair value prices, subject to oversight by the Board.  If market quotations are not readily available, the security will be valued at fair value (the amount which the owner might reasonably expect to receive for the security upon its current sale) as determined in good faith by the Adviser ("Fair Value Pricing"), subject to oversight by the Board.  The Adviser must use reasonable diligence in determining whether market quotations are readily available.  If, for example, the Adviser determines that one source of market value is unreliable, the Adviser must diligently seek market quotations from other sources, such as other brokers or pricing services, before concluding that market quotations are not available.  Fair Value Pricing is not permitted when market quotations are readily available.

Fixed income securities generally are valued using market quotations provided by a pricing service.  If the Adviser decides that a price provided by the pricing service does not accurately reflect the fair market value of the securities, when prices are not readily available from a pricing service, or when restricted or illiquid securities are being valued, securities are valued at fair value as determined in good faith by the Adviser, in conformity with guidelines adopted by and subject to oversight of the Board.

Short term investments in fixed income securities with maturities of less than 60 days when acquired, or which subsequently are within 60 days of maturity, may be valued by using the amortized cost method of valuation, when the Board has determined that it will represent fair value.

Semi-Annual Report | 13

ONE ROCK FUND

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

MAY 31, 2021 (UNAUDITED)

Financial Futures Contracts – The Fund may invest in financial and stock futures contracts. Upon entering into a financial futures contract, the Fund is required to pledge to the broker an amount of cash, U.S. government securities, or other assets, equal to a certain percentage of the contract amount (initial margin deposit). The contracts are marked-to-market daily and the resulting changes in value are accounted for as unrealized gains and losses. Subsequent payments, known as “variation margin,” are made or received by the Fund each day, depending on the daily fluctuations in the fair value of the underlying security. The Fund recognizes a gain or loss equal to the daily variation margin. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the amount invested in the contract.  Should market conditions move unexpectedly, the Fund may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. The use of futures transactions involves the risk of imperfect correlation in movements in the price of futures contracts, interest rates, and the underlying hedged assets. Refer to the Fund’s Schedule of Investments for details regarding open futures contracts as of May 31, 2021.

The Fund may buy or sell stock index futures to increase exposure to the broad equity market, hedge market exposure of an existing portfolio, or decrease overall market exposure.  The Adviser may invest in stock index futures in this way to achieve a desired portfolio stock, or stock equivalent, exposure. The Fund’s use of futures involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) leverage risk (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the futures contract may not correlate perfectly with the underlying index. Investments in futures involve leverage, which means a small percentage of assets invested in futures can have a disproportionately large impact on the Fund. This risk could cause the Fund to lose more than the principal amount invested. Futures contracts may become mispriced or improperly valued when compared to the adviser’s expectation and may not produce the desired investment results. Additionally, changes in the value of futures contracts may not track or correlate perfectly with the underlying index because of temporary, or even long-term, supply and demand imbalances and because futures do not pay dividends unlike the stocks upon which they are based.

The Fund also invests in short-term opportunities through the trading of common stocks and/or stock index futures in situations that the Adviser believes to be a market overreaction to recently disclosed public news.  Such situations can be caused for many reasons including earnings reports, analyst rating changes, competitor changes in business outlook, secondary stock offerings, industry headline news, extraordinary events, economic reports or monetary actions. In these circumstances, business momentum may not be a factor and the expectation is for a short-term trade.

Options – When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase

Semi-Annual Report | 14

ONE ROCK FUND

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

MAY 31, 2021 (UNAUDITED)

transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security or currency in determining whether the Fund has realized a gain or loss. If a put option is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. See Note 4 for additional disclosure on the Fund’s options transactions during the period.

Short Sales of Investments – The Fund may make short sales of investments, which are transactions in which a Fund sells a security it does not own in anticipation of a decline in the fair value of that security. To complete such a transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by purchasing it at the market price at the time of replacement. The broker retains the proceeds of short sales to the extent necessary to meet margin requirements until the short position is closed out.

If a security pays a dividend while the Fund holds it short, the Fund will need to pay the dividend to the original owner of the security. Since the Fund borrowed the shares and sold them to a third party, the third party will receive the dividend from the security and the Fund will pay the original owner the dividend directly. The Fund is not entitled to the dividend because it does not own the shares. A gain, limited to the price at which the Fund sold the security short, or a loss, unlimited in size, will be recognized upon the termination of a short sale.

Short sales and written options are collateralized by pledged securities held at Interactive Brokers, LLC. The collateral required is determined daily by reference to the market value of the short and written positions. The Fund is required to maintain margin cash balances at the prime broker sufficient to satisfy its short sales positions on a daily basis. Refer to the Statement of Assets and Liabilities for amounts due to/from broker.

Fair Value Measurements

GAAP defines fair value as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date and also establishes a framework for measuring fair value, and a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability.  The three-tier hierarchy seeks to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the Fund’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

Equity securities (common stocks). Securities traded on a national securities exchange (or reported on the NASDAQ national market) are stated at the last reported sales price on the day of valuation. To the extent these securities are actively traded, and valuation adjustments are not applied, they are categorized in Level 1 of the fair value hierarchy. Certain foreign securities may be fair valued using a pricing service that considers the correlation of the trading patterns of the foreign security to the intraday trading in the U.S. markets for investments such as American Depositary Receipts, financial futures, exchange traded funds, and the movement of the certain indexes of securities based on a statistical analysis of the historical relationship and that are categorized in Level 2. Preferred stock and other equities traded on inactive markets or valued by reference to similar instruments are also categorized in Level 2.

Short-term investments.  Short term investments are valued using amortized cost, which approximates fair value.  These securities will be categorized in Level 1 of the fair value hierarchy.

Derivative instruments (future contracts and options). Listed derivative instruments that are actively traded, including futures contracts, are valued based on quoted prices from the exchange and are categorized in Level 1 of the fair value hierarchy. Options are valued at the last sales prices on the valuation date if the last sales price is between the closing bid and asked prices. Otherwise, options are valued at the closing bid price. These securities will be categorized in Level 2 of the fair value hierarchy if valued at other than closing price.

A description of the valuation techniques applied to the Fund’s major categories of assets and liabilities and other financial instruments measured at fair value on a recurring basis follows.

Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the company has the ability to access.

Level 2 - Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly. These inputs may include quoted prices for the identical instrument on an inactive market, prices for similar instruments, interest rates, prepayment speeds, credit risk, yield curves, default rates, and similar data.

Level 3 - Unobservable inputs for the asset or liability to the extent that relevant observable inputs are not available, representing the company's own assumptions about the assumptions that a market participant would use in valuing the asset or liability, and that would be based on the best information available.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in the security.

The Adviser consistently assesses the value of existing positions in the Fund.  Generally, the Adviser exercises patience when fundamentals are stable but prices volatile.  The Adviser may at times write covered call options on a small portion of existing common stock positions in the Fund to generate premium. The Fund may trade financial instruments where they are considered to be a seller of credit derivatives in accordance with authoritative guidance under GAAP on derivatives and hedging.  The Fund may purchase and write (i.e., sell) put and call options. Such options may relate to particular securities or stock indices, and may or may not be listed on a domestic or foreign securities exchange and may or may not be issued by Interactive Brokers, LLC. Option trading is a highly specialized activity that entails greater than ordinary investment risk. Options may be more volatile than the underlying instruments, and therefore, on a percentage basis, an investment in options may be subject to greater fluctuation than an investment in the underlying instruments themselves.

A call option for a particular security gives the purchaser of the option the right to buy, and the writer (seller) the obligation to sell, the underlying security at the stated exercise price at any time prior to the expiration of the option, regardless of the market price of the security. The premium paid to the writer is in consideration for undertaking the obligation under the option contract. A put option for a particular security gives the purchaser the right to sell the security at the stated exercise price at any time prior to the expiration date of the option, regardless of the market price of the security.

The Fund may buy or sell stock index futures to increase exposure to the broad equity market, hedge market exposure of an existing portfolio, or decrease overall market exposure. The Adviser may invest in stock index futures in this way to achieve a desired portfolio stock, or stock equivalent, exposure.

The primary reason for the difference between the book and tax cost of investments and premiums from written options is the tax deferral of losses on wash sales.

The Fund’s tax basis net capital gains/(losses) and distributable earnings on a tax basis are determined only at the end of each fiscal year.

As of November 30, 2020, the components of distributable earnings on a tax basis were as follows:

NOTE 10.  MARKET RISK

Overall market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels and political events affect the securities markets. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issue, recessions and depressions, or other events could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s net asset value, and may impair market liquidity, thereby increasing liquidity risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.  During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates can have the same impact on all types of securities and instruments.

An outbreak of infectious respiratory illness caused by a novel coronavirus known as COVID-19 was first detected in China in December 2019 and has now been detected globally. This coronavirus has resulted in travel restrictions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, prolonged quarantines, cancellations, supply chain disruptions, and lower consumer demand, as well as general concern and uncertainty. The impact of COVID-19, and other infectious illness outbreaks that may arise in the future, could adversely affect the economies of many nations or the entire global economy, individual issuers and capital markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illnesses in emerging market countries may be greater due to generally less established healthcare systems. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The duration of the COVID-19 outbreak and its effects cannot be determined with certainty.

NOTE 11.  SECTOR CONCENTRATION RISK

Sector concentration risk is the possibility that securities within the same sector will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of the shares of a mutual fund that invests in a broader range of sectors. Additionally, some sectors could be subject to greater government regulation that other sectors. Therefore, changes in regulatory policies for those sectors may have a material effect on the value of securities issued by companies in those sectors.

As of May 31, 2021, the Fund had 58.72% of its net asset value invested in the technology sector. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector re heavily dependent on patent and intellectual property rights. The loss or impairment of these right may adversely affect the profitability of these companies.

Expense Example

As a shareholder of the Fund, you incur ongoing costs which consist of, management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period, December 1, 2020 through May 31, 2021.  

Actual Expenses

The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period" to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table below provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in each Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

	Beginning Account Value	Ending Account Value	Expenses Paid During the Period*
	December 1, 2020	May 31, 2021	December 1, 2020 to May 31, 2021
Actual	$1,000.00	$1,047.34	$8.93
Hypothetical
(5% Annual Return       before expenses)	$1,000.00	$1,016.21	$8.80
* Expenses are equal to the Fund's annualized expense ratio of 1.75%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).
