† Payment is based on a percentage of the index. Reference entities are a number of individual issuers comprising the index.

†† For each credit derivative with sold protection, the credit ratings of the entities referenced, as rated by any rating organization, are included in the equivalent S&P Global Ratings or Western Asset Management Company's rating category, as applicable. The reference entity rating represents the likelihood of a potential payment by the Fund if the referenced entity experiences a credit event as of period end. Notional amounts represent the maximum potential amount of future payments (undiscounted) the Fund could be required to make under the credit derivatives with sold protection.

Notes to Portfolio of Investments (Unaudited) (Continued)

Investment Valuation

The net asset value of each Fund’s shares is determined once daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), on each day the NYSE is open for trading (a “business day”). The NYSE normally closes at 4:00 p.m. Eastern Time, but may close earlier on some days. If the NYSE is scheduled to close early, the business day will be considered to end as of the time of the NYSE’s scheduled close. A Fund will not treat an intraday disruption in NYSE trading or other event that causes an unscheduled closing of the NYSE as a close of business of the NYSE for these purposes; instead, MML Investment Advisers, LLC (“MML Advisers”) will determine the fair value of a Fund’s securities in accordance with MML Advisers’ fair valuation policy and procedures. On holidays and other days when the NYSE is closed, each Fund’s net asset value generally is not calculated and the Funds do not anticipate accepting buy or sell orders. However, the value of each Fund’s assets may still be affected on such days to the extent that a Fund holds foreign securities that trade on days that foreign securities markets are open.

Equity securities and derivative contracts that are actively traded on a national securities exchange or contract market are valued on the basis of information furnished by a pricing service, which provides the last reported sale price, or, in the case of futures contracts, the settlement price, for securities or derivatives listed on the exchange or contract market or the official closing price on the NASDAQ National Market System (“NASDAQ System”), or in the case of over-the-counter (“OTC”) securities for which an official closing price is unavailable or not reported on the NASDAQ System, the last reported bid price. Portfolio securities traded on more than one national securities exchange are valued at the last price at the close of the exchange representing the principal market for such securities. Debt securities are valued on the basis of valuations furnished by a pricing service, which generally determines valuations taking into account factors such as institutional-size trading in similar securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. Shares of other open-end mutual funds are valued at their closing net asset values as reported on each business day.

Investments for which market quotations are readily available are marked to market daily based on those quotations. Market quotations may be provided by third-party vendors or market makers, and may be determined on the basis of a variety of factors, such as broker quotations, financial modeling, and other market data, such as market indexes and yield curves, counterparty information, and foreign exchange rates. U.S. Government and agency securities may be valued on the basis of market quotations or using a model that may incorporate market observable data such as reported sales of similar securities, broker quotes, yields, bids, offers, quoted market prices, and reference data. The fair values of OTC derivative contracts, including forward, swap, and option contracts related to interest rates, foreign currencies, credit standing of reference entities, equity prices, or commodity prices, may be based on market quotations or may be modeled using a series of techniques, including simulation models, depending on the contract and the terms of the transaction. The fair values of asset-backed securities and mortgage-backed securities are estimated based on models that consider the estimated cash flows of each debt tranche of the issuer, established benchmark yield, and estimated tranche-specific spread to the benchmark yield based on the unique attributes of the tranche, including, but not limited to, prepayment speed assumptions and attributes of the collateral.

The Board of Trustees (“Trustees”) have designated MML Advisers as the Funds’ “valuation designee,” responsible for determining the fair value, in good faith, of securities and other instruments held by the Funds for which market quotations are not readily available or for which such market quotations or values are considered by MML Advisers or a subadviser to be unreliable (including, for example, certain foreign securities, thinly-traded securities, certain restricted securities, certain initial public offerings, or securities whose values may have been affected by a significant event). It is possible that a significant amount of a Fund’s assets will be subject to fair valuation in accordance with MML Advisers’ fair valuation policy and procedures. The fair value determined for an investment by MML Advisers may differ from recent market prices for the investment and may be significantly different from the value realized upon the sale of such investment.

Notes to Portfolio of Investments (Unaudited) (Continued)

The Funds may invest in securities that are traded principally in foreign markets and that trade on weekends and other days when the Funds do not price their shares. As a result, the values of the Funds’ portfolio securities may change on days when the prices of the Funds’ shares are not calculated. The prices of the Funds’ shares will reflect any such changes when the prices of the Funds’ shares are next calculated, which is the next business day.  The Funds may use fair value pricing more frequently for securities primarily traded in foreign markets because, among other things, most foreign markets close well before the Funds value their securities. The earlier close of these foreign markets gives rise to the possibility that significant events, including broad market moves, may have occurred in the interim. The Funds’ investments may be priced based on fair values provided by a third-party vendor, based on certain factors and methodologies applied by such vendor, in the event that there is movement in the U.S. market, between the close of the foreign market and the time the Funds calculate their net asset values. All assets and liabilities expressed in foreign currencies are converted into U.S. dollars at the mean between the buying and selling rates of such currencies against the U.S. dollar at the end of each business day.

Investments in equity or debt issued by privately held companies or funds (“Private Company” or collectively, the “Private Companies”) and any other investments fair valued using significant unobservable inputs may be fair valued using one or a combination of, but not limited to, the following inputs:

Market approach: (i) recent market transactions, including subsequent rounds of financing, in the underlying investment or comparable issuers; (ii) recapitalizations and other transactions across the capital structure; and (iii) market multiples of comparable issuers.

Income approach: (i) future cash flows discounted to present value and adjusted as appropriate for liquidity, credit, and/or market risks; (ii) quoted prices for similar investments or assets in active markets; and (iii) other risk factors, such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, recovery rates, liquidation amounts, and/or default rates.

Cost approach: (i) audited or unaudited financial statements, investor communications, and financial or operational metrics issued by the Private Company; (ii) changes in the valuation of relevant indexes or publicly traded companies comparable to the Private Company; (iii) relevant news and other public sources; and (iv) known secondary market transactions in the Private Company’s interests and merger or acquisition activity in companies comparable to the Private Company.

Investments in series of preferred stock issued by Private Companies are typically valued utilizing Market approach in determining the enterprise value of the company. Such investments often contain rights and preferences that differ from other series of preferred and common stock of the same issuer. Valuation techniques such as the current value method (“CVM”), an option pricing model (“OPM”), a probability weighted expected return model (“PWERM”), or a hybrid of those techniques are used in allocating enterprise value of the company, as deemed appropriate under the circumstances. The CVM allocates value among the various parts of a company’s capital structure assuming that the value of convertible preferred stock is represented by the most favorable claim the preferred stockholders have on the enterprise value as of the valuation date. The use of OPM and PWERM techniques involve a determination of the exit scenarios of the investment in order to appropriately allocate the enterprise value of the company among the various parts of its capital structure.

Notes to Portfolio of Investments (Unaudited) (Continued)

The Private Companies are not subject to the public company disclosure, timing, and reporting standards as other investments held by a Fund. Typically, the most recently available information for a Private Company is as of a date that is earlier than the date a Fund is calculating its net asset value. This factor may result in a difference between the value of the investment and the price a Fund could receive upon the sale of the investment.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-tier hierarchy is utilized to maximize the use of observable market data inputs 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, for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below. The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those investments and the determination of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to each security.

Level 1 – quoted prices (unadjusted) in active markets for identical investments that the Funds can access at the measurement date

Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

Level 3 – significant unobservable inputs, to the extent observable inputs are not available (including the Funds’ own assumptions in determining the fair value of investments)

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of markets, and other characteristics particular to the security. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

Changes in valuation techniques may result in transfers in or out of an investment’s assigned Level within the hierarchy. In addition, in periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition, as well as changes related to liquidity of investments, could cause a security to be reclassified between Levels.

In certain cases, the inputs used to measure fair value may fall into different Levels of the fair value hierarchy. In such cases, for disclosure purposes, the Level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest Level input that is significant to the overall fair value measurement.

Derivative Instruments

Derivatives are financial instruments whose values are based on the values of one or more underlying indicators, such as a security, asset, currency, interest rate, or index. Derivative transactions can create investment leverage and may be highly volatile. Losses from derivatives can be substantially greater than the derivatives’ original cost and can sometimes be unlimited. A Fund may not be able to close out a derivative transaction at a favorable time or price.

Notes to Portfolio of Investments (Unaudited) (Continued)

Please refer to the Funds’ most recent Annual/Semiannual reports and Prospectus(es) and Statement(s) of Additional Information which can be found on the Securities and Exchange Commission’s EDGAR database on its website at http://www.sec.gov for more information regarding the derivatives and other investments held by the Fund(s).

Securities Lending

Each Fund may lend its securities; however, lending cannot exceed 33% of the total assets of the Fund taken at current value. The Funds’ securities lending activities are governed by a Securities Lending Agency Agreement (“Lending Agreement”) between each Fund and the lending agent (“Agent”). The Lending Agreement authorizes the Agent to lend portfolio securities held by a Fund to approved borrowers (each, a “Borrower”).

Each Fund expects that in connection with any securities on loan, the loan will be secured continuously by collateral consisting of cash (U.S. currency) and/or securities (U.S. Treasury and Agency obligations) adjusted daily to have value at least equal to the current market value of the securities loaned. The market value of the loaned securities is determined at the close of business of a Fund and any additional collateral is delivered to the Fund the next business day. The Funds bear the risk of loss with respect to the investment of cash collateral. As with other extensions of credit, the Funds may bear the risk of delay in recovery of the loaned securities or even loss of rights in the collateral should the Borrower of the securities fail financially. Pursuant to the Lending Agreement, the Agent has provided indemnification to the Funds in the event of default by a Borrower with respect to a loan. The Funds receive compensation for lending their securities in the form of a securities loan fee paid by the Borrower, as well as a share of the income earned on investment of the cash collateral received for the loaned securities. At September 30, 2022, the Funds’ collateral was equal to or greater than 100% of the market value of securities on loan and all of the Funds’ cash collateral was invested in the State Street Navigator Securities Lending Government Money Market Portfolio.

Subject to the terms of the Lending Agreement and the agreement between the Agent and the applicable Borrower (“Borrowing Agreement”), security loans can be terminated by the Agent, the Fund, or the Borrower and the related securities must be returned within the earlier of the customary settlement period for such securities or the period of time specified in the Borrowing Agreement.

Accounting for Investment Transactions

Investment transactions are accounted for on the trade date. Realized gains and losses on sales of investments and unrealized appreciation and depreciation of investments are computed by the specific identification cost method. Proceeds received from litigation, if any, are included in realized gains on investment transactions for any investments that are no longer held in the portfolio and as a reduction in cost for investments that continue to be held in the portfolio. Interest income, adjusted for amortization of discounts and premiums on debt securities, is earned from the settlement date and is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date. Withholding taxes on foreign interest, dividends, and capital gains have been provided for in accordance with the applicable country’s tax rules and rates. Foreign dividend income is recorded on the ex-dividend date or as soon as practicable after the Fund determines the existence of a dividend declaration after exercising reasonable due diligence. Distributions received on securities that represent a return of capital or capital gains are recorded as a reduction of cost of investments and/or as a realized gain.

Foreign Currency Translation

The books and records of the Funds are maintained in U.S. dollars. The market values of foreign currencies, foreign securities, and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the mean of the buying and selling rates of such currencies against the U.S. dollar at the end of each business day. Purchases and sales of foreign securities and income and expense items are translated at the rates of exchange prevailing on the respective dates of such transactions. The Funds do not isolate that portion of the results of operations arising from changes in the exchange rates from that portion arising from changes in the market prices of securities. Net realized foreign currency gains and losses resulting from changes in exchange rates include foreign currency gains and losses between trade date and settlement date on investment securities transactions, foreign currency transactions, and the difference between the amounts of dividends or interest recorded on the books of the Funds and the amount actually received.

Foreign Securities

The Strategic Emerging Markets Fund invests substantially all of its assets in foreign securities. The other Funds, except for the Blend Fund, iShares 60/40 Allocation Fund, and iShares 80/20 Allocation Fund, may also invest in foreign securities. In addition, certain Underlying ETFs may invest in foreign securities. Foreign securities, including American Depositary Receipts, are subject to additional risks compared to securities of U.S. issuers, including international trade, currency, political, regulatory, public health, and diplomatic risks. In addition, fluctuations in currency exchange rates may favorably or unfavorably affect the values of foreign securities and the price of a Fund’s shares. Emerging markets securities are subject to greater risks than securities issued in developed foreign markets, including less liquidity, less stringent investor protection and disclosure standards, less reliable settlement practices, greater price volatility, higher relative rates of inflation, greater political, economic, and social instability, greater custody and operational risks, greater risk of new or inconsistent government treatment of or restrictions on issuers and instruments, and greater volatility in currency exchange rates, and are more susceptible to environmental problems.

Federal Income Tax

It is each Fund’s intent to continue to comply with the provisions of Subchapter M of the Internal Revenue Code of 1986, as amended, applicable to a regulated investment company. Under such provisions, the Funds would not be subject to federal income taxes on their ordinary income and net realized capital gains to the extent they are distributed or deemed to have been distributed to their shareholders. Therefore, the Funds have not made any provision for federal income tax.

Dividends and Distributions to Shareholders

Dividends from net investment income and distributions of any net realized capital gains of each Fund are declared and paid annually and at other times as may be required to satisfy tax or regulatory requirements.

Distributions to shareholders are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. As a result, net investment income and net realized capital gains on investment transactions for a reporting period may differ significantly from distributions during such period.

3. Federal Income Tax Information

At September 30, 2022, the aggregate cost of investments and the unrealized appreciation (depreciation) in the value of all investments owned by the Fund(s), as computed on a federal income tax basis, were as follows:

4. New Accounting Pronouncements

In January 2021, FASB issued Accounting Standards Update 2021-01 — Reference Rate Reform (Topic 848) — Scope (“ASU 2021-01”) as an update to Accounting Standards Update 2020-04 — Reference Rate Reform (Topic 848) — Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”) in order to make certain clarifications. ASU 2020-04 and ASU 2021-01 provide optional temporary financial reporting relief from the effect of certain types of contract modifications due to the planned discontinuation of the London Interbank Offered Rate (“LIBOR”) and other interbank-offered based reference rates. The temporary relief provided by ASU 2020-04 and ASU 2021-01 is effective for certain reference rate-related contract modifications that occur during the period March 12, 2020 through December 31, 2022. Management does not believe the impact of adopting ASU 2020-04 and ASU 2021-01 will have a material impact on the financial statements.

In June 2022, FASB issued Accounting Standards Update 2022-03 — Fair Value Measurement (Topic 820) — Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”). ASU 2022-03 clarifies the guidance in Topic 820 to indicate that a contractual sale restriction should not be considered in the fair value of an equity security subject to such a restriction, and requires entities with investments in equity securities subject to contractual sale restrictions to disclose certain qualitative and quantitative information about such securities. ASU 2022-03 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, and allows for early adoption. ASU 2022-03 will only be applicable to an equity security in which the contractual arrangement that restricts its sale is executed or modified on or after the adoption date. Management is currently evaluating the impact of applying this update.

5. Coronavirus (COVID-19) Pandemic

The global pandemic outbreak of the novel coronavirus known as COVID-19 and efforts to contain its spread have produced, and will likely continue to produce, substantial market volatility, severe market dislocations and liquidity constraints in many markets, exchange trading suspensions and closures, higher default rates, and global business disruption, and they may result in future significant adverse effects, such as declines in global financial markets and a substantial economic downturn or recession throughout the world. Such factors may have a significant adverse effect on a Fund’s performance and have the potential to impair the ability of a Fund’s investment adviser, subadviser, or other service providers to serve the Fund and could lead to disruptions that negatively impact the Fund.

6. Russia-Ukraine War

In February 2022, Russia commenced a large-scale military attack on Ukraine. The outbreak of hostilities between the two countries could result in more widespread conflict and could have a severe adverse effect on the regional and the global financial markets and economies. One or more of the Underlying Funds hold positions in securities or other instruments that are economically tied to Russia. Investments in Russia are subject to political, economic, legal, market, and currency risks, as well as the risks related to the economic sanctions on Russia, Russian individuals, and Russian corporate and banking entities imposed by the United States and/or other countries. Such sanctions — which affect companies in many sectors, including energy, financial services, and defense, among others — could adversely affect the global energy and financial markets and, thus, could affect the value of a Fund’s investments, even beyond any direct exposure the Fund may have to Russian issuers or the adjoining geographic regions. Such sanctions may also result in a decline in the value and liquidity of Russian securities and a weakening of the ruble, and will impair a Fund’s ability to buy, sell, receive, or deliver Russian securities. In addition, certain transactions have been or may be prohibited and/or existing investments have or may become illiquid (e.g., because transacting in certain existing investments is prohibited), which could cause a Fund to sell other portfolio holdings at a disadvantageous time or price in order to meet shareholder redemptions.

7. Subsequent Events

In preparation of these financial statements, management has evaluated the events and transactions subsequent to September 30, 2022, through the date when the Portfolios of Investments were issued, and determined that there are no subsequent events or transactions that would require adjustments to or disclosures in the Funds' Portfolios of Investments other than those disclosed below.

Effective November 4, 2022, the Equity Momentum Fund and the Special Situations Fund were liquidated.
