To Our Shareholders

“In MassMutual’s view, retirement investors may be well served by maintaining an investment strategy that is suited to how comfortable they are with the markets’ ups and downs, how long they have to save and invest, and what their specific financial goals are.”

March 31, 2016

Welcome to the MassMutual Select Funds Semiannual Report, covering the six months ended March 31, 2016. U.S. stocks, for the most part, outperformed their foreign counterparts, reflecting the ongoing strength of the U.S. economy during the period. Investors continued to closely monitor economic data releases in their vigil over the potential timing for the U.S. Federal Reserve’s (the “Fed”) long-awaited launch of interest rate increases – a source of investor speculation for most of 2015. During the reporting period, low oil prices and China’s continued economic difficulties continued to capture investors’ attention. Against this backdrop, the price of West Texas Intermediate crude oil started the period at nearly $45 per barrel and declined to nearly $37 at the end of March. This masked the extreme volatility of the commodity, however – whose price reached as high as $47.88 on November 3, 2015, and as low as $26.19 on February 11, 2016. Gasoline prices followed a similar pattern, starting out the six-month period at an average of $2.29 – before settling at $2.06 on March 31, 36 cents lower than the same time in 2015. The price of gold also fluctuated over the course of the six months, starting the period at $1,119 per ounce, before finishing the first quarter at $1,237.

Key events that characterized the period

Thanks to a robust October rally, U.S. stocks performed relatively well in the final quarter of 2015 against the backdrop of a somewhat disappointing first three quarters, when several factors had kept share prices from making much upward headway. These included weak commodity prices – especially crude oil, uncertainty about the timing of the Fed’s first interest rate hike since 2006, investor concerns about the strength and durability of the U.S. economic recovery, and worries over China and emerging markets worldwide.

After an extremely volatile third quarter of 2015, share prices recovered strongly in October, with two of the most widely followed U.S. equity benchmarks, the Dow Jones Industrial Average^SM (the “Dow”) and the S&P 500^® Index, turning in their best monthly gains since October 2011. Investor fears about China and crude oil eased, and a weak September payroll number fueled hopes that the Fed might delay raising short-term interest rates; however, the October and November employment reports were considerably stronger. This renewed talk of a rate increase – which, in fact, finally occurred at the mid-December meeting, when the Fed hiked the target range for the federal funds rate – the Fed’s overnight bank lending rate – to 0.25%-0.50% from 0%-0.25%. Elsewhere, crude oil broke to another new low for the year in December and ended 2015 with an annual decline of 31% after falling almost 50% in 2014. These factors led to choppy market action over the final two months of the year.

The U.S. economy continued to improve, although results were mixed. For example, in mid-October, several housing reports yielded generally positive results, whereas later that month, the housing outlook was muddled by new home sales figures that were the lowest since November 2014. On the other hand, there was mostly good news on the employment front, as jobless claims experienced a favorable downward trend during the fourth quarter – and first-time jobless claims dropped to a 42-year low in mid-December. This was despite the October Job Openings and Labor Turnover Survey, which in December showed a decline in job openings from 5.526 million to 5.383 million. Employment news remained largely positive, however, as even the manufacturing sector, which struggled from falling exports due to a strong dollar, posted encouraging results in the fourth quarter of 2015.

MassMutual Select Funds – President’s Letter to Shareholders (Unaudited) (Continued)

After experiencing a steep plunge and vigorous recovery as recently as August and October, respectively, U.S. stocks repeated that scenario in the first quarter of 2016. In both cases, concerns about China’s slowing economy and falling crude oil prices helped to drive weakness in share prices. Adding to these concerns at the start of 2016 was fear of slowing global and domestic economic growth, the latter underscored by initial estimates that U.S. gross domestic product (“GDP”) expanded by a disappointing 0.7% rate in the fourth quarter of 2015, although that number was subsequently revised upward.

Share prices continued to struggle early in February, as global equity markets moved roughly in tandem with the price of oil, which declined early on, but rallied later in the month on hopes that producers would curtail supply. Concerns about the European banking system also worried investors early in February. In the U.S., a weak January employment report stoked fears that a recession could be on the horizon. However, later in the quarter, upward revisions in estimated fourth-quarter U.S. economic growth, first to 1.0% and ultimately to 1.4%, helped the equity markets rebound. The employment picture also brightened, as February’s nonfarm payrolls came in significantly stronger than the previous two months’. At the same time, the payroll numbers for both January and December were revised upward.

The rally in equities continued in March, with the Fed doing its part by reassuring investors that the central bank would be cautious about implementing further hikes in short-term interest rates. Stocks ended March near their highs for the quarter and only a scant few percent off their all-time highs.

The major stock indexes in the U.S. advanced for the six months ended March 31, 2016 – largely, but not entirely – outperforming foreign developed and emerging markets. The blue-chip Dow climbed 10.07% to lead the major market indexes for the period. Next were the large-cap stock S&P 500 Index, which rose 8.49%; and the technology-heavy NASDAQ Composite^® Index, which advanced 6.07%. The Russell 2000^® Index, a benchmark of small-cap stocks, gained a much more modest 2.02% over the six months. In international markets, the MSCI EAFE Index, an indicator of foreign developed-market stocks, posted a mere 1.56% advance, while the MSCI Emerging Markets Index, a measure of the performance of emerging stock markets throughout the world, had a more impressive 6.41% return. Fixed-income investments advanced somewhat during the period, with the Barclays U.S. Aggregate Bond Index returning 2.44%.*

Each share class of a Fund represents an interest in the same portfolio of assets. The principal difference among the classes is the level of service and administration fees, and shareholder and distribution service expenses borne by the classes. Because each class will have different fees and expenses, performance and share prices will vary between the classes. The classes of shares are offered to different types of investors, as outlined in the Funds’ Prospectus.

On May 13, 2015, the Board of Trustees (“Trustees”) approved a change in the fiscal year end of the Funds from December 31 to September 30. Accordingly, the Funds’ financial statements and related notes include information as of the nine month period ended September 30, 2015, and the year ended December 31, 2014.

Effective March 21, 2014, Class L shares of the S&P 500 Index Fund, S&P Mid Cap Index Fund, Russell 2000 Small Cap Index Fund, and MSCI EAFE International Index Fund merged into Class Y shares (now known as Administrative Class shares). Effective April 1, 2014, Class Z shares were renamed Class I shares, Class S shares were renamed Class R5 shares, Class Y shares were renamed Service Class shares, Class L shares were renamed Administrative Class shares, and Class N shares were renamed Class R3 shares, for each Fund, other than the Total Return Bond Fund, S&P 500 Index Fund, S&P Mid Cap Index Fund, Russell 2000 Small Cap Index Fund, and MSCI EAFE International Index Fund. Effective April 1, 2014, Class Z shares were renamed Class I shares, Class S shares were renamed Class R5 shares, Class Y shares were renamed Service Class shares, Class L shares were renamed Administrative Class shares, Class A shares were renamed Class R4 shares, and Class N shares were renamed Class R3 shares for the Total Return Bond Fund.

2. Significant Accounting Policies

The following is a summary of significant accounting policies followed consistently by each Fund in the preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“generally accepted accounting principles”). The preparation of the financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

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.

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. Restricted securities are generally valued at a discount to similar publicly traded securities.

Investments for which market quotations are not available or for which a pricing service or vendor does not provide a value, or for which such market quotations or values are considered by the investment adviser or 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) are stated at fair valuations determined in good faith by the Funds’ Valuation Committee¹ in accordance with procedures approved annually by the Board of Trustees (“Trustees”), and under the general oversight of the Trustees. The Funds’ Valuation Committee employs various methods to determine fair valuations including a regular review of significant inputs and assumptions and review of any related market activity. The Funds’ Valuation Committee reports to the Trustees at their regularly scheduled meetings. It is possible that fair value prices will be used by the Funds to a significant extent. The value determined for an investment using the Funds’ fair value procedures may differ from recent market prices for the investment and may be significantly different from the value realized upon the sale of such investment.

¹  The Valuation Committee consists of the President, Treasurer, Assistant Treasurers, Vice Presidents (except for the CCO), Assistant Vice Presidents, Secretary, and Assistant Secretaries of the Trust, as well as such alternate members as the Trustees may from time to time designate. The Valuation Committee reviews and determines the fair valuation of portfolio securities and the Funds’ pricing procedures in general.

Notes to Financial Statements (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.

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

The types of assets and liabilities categorized in Level 1 generally include actively traded domestic and certain foreign equity securities, derivatives actively traded on a national securities exchange (such as some warrants, rights, futures, and options), and shares of open-end mutual funds.

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

The types of assets and liabilities categorized in Level 2 generally include debt securities such as U.S. Government and agency securities, mortgage-backed securities, asset-backed securities, municipal obligations, sovereign debt obligations, bank loans, corporate bonds, and those securities valued at amortized cost; OTC derivatives such as swaps, options, swaptions, and forward foreign currency exchange contracts; certain restricted securities; and non-exchange traded equity securities and certain foreign equity securities traded on particular foreign exchanges that close before the Funds determine their net asset values.

Level 3 – significant unobservable inputs (including the Funds’ own assumptions in determining the fair value of investments)

The types of assets and liabilities categorized in Level 3 generally include securities for which prices, spreads, or any of the other aforementioned significant inputs are unobservable. Generally, securities whose trading has been suspended or that have been de-listed from their current primary trading exchange; securities in default or bankruptcy proceedings for which there is no current market quotation; securities and certain derivatives valued by broker quotes which may include brokers’ assumptions; and any illiquid Rule 144A securities or restricted securities issued by non-public entities are categorized in Level 3.

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.

214

Notes to Financial Statements (Continued)

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 Level 1, Level 2, or Level 3.

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.

The Diversified Value Fund, Focused Value Fund, Fundamental Growth Fund and Growth Opportunities Fund characterized all long-term investments at Level 1, and all short-term investments at Level 2, as of March 31, 2016. The Strategic Bond Fund characterized all forward sale commitments at Level 2, as of March 31, 2016. For each Fund noted in the preceding sentences, the level classification by major category of investments is the same as the category presentation in the Portfolio of Investments.

The following is the aggregate value by input level, as of March 31, 2016, for the remaining Funds’ investments and the Strategic Bond Fund’s other investments:

** Transfers occurred between Level 2 and Level 3 as inputs were less observable.

*** Represents a security at $0 value as of September 30, 2015.

††† Represents a security at $0 value as of March 31, 2016.

None of the unobservable inputs, individually or collectively, had a material impact on the Fund(s), other than those disclosed below.

The Small Cap Growth Equity Fund fair values certain of its Level 3 investments using acquisition cost, although the transaction may not have occurred during the current reporting period. These investments are generally privately held investments, but may include defaulted securities and new debt issuances. There may not be a secondary market for such investments, and/or there are a limited number of investors. The determination to fair value such investments at cost is based upon factors consistent with the principles of fair value measurement that are reasonably available to the Valuation Committee. Valuations are reviewed by members of the Valuation Committee utilizing available market information to determine if the carrying value of these investments should be adjusted. Such market data may include, but is not limited to, observations of the trading multiples of public companies considered comparable to the private companies being valued, financial or operational information released by the company, and/or news or corporate events that affect the investment, also referred to as enterprise value (EV) to earnings before interest, taxes, depreciation, and amortization (EBITDA) ratios. Valuations may be adjusted to account for company-specific issues, the lack of liquidity inherent in a nonpublic investment and the fact that comparable public companies are not identical to the investments being fair valued by the Small Cap Growth Equity Fund. All market variables are assessed on a regular frequency and calibrated as necessary.

Derivative Instruments

Derivatives are financial instruments whose values are based on the values of one or more indicators, such as a security, asset, currency, interest rate, or index. Derivative transactions can create investment leverage and may be highly volatile. Gains or 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. For those Funds that held derivatives during the period ended March 31, 2016, the following tables show how the Fund used these types of derivatives during the period (marked with an “A”), as well as additional uses, if any, it may have for them in the future (marked with an “M”).

* Represents the net amount receivable from the counterparty in the event of default.

** Represents the net amount payable to the counterparty in the event of default.

*** The amount presented here may be less than the total amount of collateral received/pledged as the net amount of derivative assets and liabilities for a counterparty cannot be less than $0.

† The amount presented here may be less than the total amount shown in the Statements of Assets and Liabilities as some derivatives held by the counterparty are not covered within the master netting agreements.

Such agreements typically permit a single net payment in the event of default, including the bankruptcy or insolvency of the counterparty. Typically, the Fund(s) and counterparties are not permitted to sell, re-pledge, or use the collateral they receive.

Notes to Financial Statements (Continued)

Further details regarding the derivatives and other investments held by the Fund(s) during the period ended March 31, 2016, are discussed below.

Foreign Currency Exchange Transactions

A Fund may engage in foreign currency exchange transactions for hedging purposes in order to protect against uncertainty in the level of future foreign currency exchange rates, or for other, non-hedging purposes.

A Fund may enter into foreign currency exchange transactions including, foreign currency futures contracts and foreign currency forward contracts. These contracts call for the Fund to deliver in the future an amount of one currency in return for an amount of another currency, at an exchange rate determined at the time the contract is entered into. Futures contracts are exchange-traded and typically have minimal exposure to counterparty risk. Forward contracts are private contractual arrangements and a Fund is subject to the risk that its counterparty will not, or will not be able to, perform its obligations. This type of arrangement may require the Fund to post margin. A Fund may also buy and sell options on currencies or currency futures contracts. When the Fund buys an option, its loss should generally be limited to the amount of the premium paid and any transaction costs. If a Fund sells an option on a currency or currency futures contract, it is subject generally to the same risks as if it had entered into a futures contract or forward contract with respect to that currency. A Fund may enter into foreign currency exchange transactions in order to hedge against changes in the values of the assets or liabilities denominated in one or more foreign currencies, or otherwise to increase or reduce a Fund’s exposure to various foreign currencies. The use of foreign currency exchange transactions may create investment leverage.

Whenever a Fund enters into a foreign currency exchange transaction, it is subject to the risk that the value of the transaction will move in a direction unfavorable to it. When the Fund uses the transactions for hedging purposes, it is likely that the Fund will have an asset or liability that will offset any loss (or gain) on the transactions, at least in part. If a Fund enters into foreign currency exchange transactions other than for hedging purposes (for example, seeking to profit from an anticipated change in the values of currencies by creating directional exposures in the portfolio with respect to one or more currencies), it will generally be subject to the same risks, but is less likely to have assets or liabilities that will offset any losses on the transactions. There can be no assurance that a Fund will be able to terminate any foreign currency exchange transaction prior to its maturity in order to limit its loss on the transaction.

Forward foreign currency contracts are marked to market daily and the change in their value is recorded by the Funds as an unrealized gain or loss. Forward foreign currency contracts are valued at the settlement price established through dealers or other market sources on the day which they are traded. When a forward foreign currency contract is extinguished, through delivery or offset by entering into another forward foreign currency contract, the Funds record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it was extinguished or offset. The notional or contractual amounts of these instruments do not necessarily represent the amounts potentially subject to risk. The measurement of the risk associated with these instruments is meaningful only when all related and offsetting transactions and counterparty risks are considered. For information regarding the accounting treatment of futures contracts and options, respectively, see “Futures Contracts” and “Options, Rights, and Warrants” below.

The Fund(s) listed in the following table had open forward foreign currency contracts at March 31, 2016. A Fund’s current exposure to a counterparty is the unrealized appreciation on the contract.

A Fund may seek to manage a variety of different risks, such as interest rate risk, equity price risk, and currency risk, through the use of futures contracts and related options (see “Foreign Currency Exchange Transactions,” above, for a discussion of the use of futures contracts in connection with currency risk).

Futures Contracts. A Fund may use interest rate futures contracts to adjust the interest rate sensitivity (duration) of its portfolio or the credit exposure of the portfolio. Interest rate futures contracts obligate the long or short holder to take or make delivery of a specified quantity of a financial instrument, such as a specific fixed-income security, during a specified future period at a specified price. A Fund may use index futures to hedge against broad market risks to its portfolio or to gain broad market exposure when it holds uninvested cash or as an inexpensive substitute for cash investments directly in securities or other assets. Securities index futures contracts are contracts to buy or sell units of a securities index at a specified future date at a price agreed upon when the contract is made and are settled in cash. Positions in futures may be closed out only on an exchange or board of trade which provides a secondary market for such futures. Because futures contracts are exchange-traded, they typically have minimal exposure to counterparty risk.

Parties to a futures contract are not required to post the entire notional amount of the contract, but rather a small percentage of that amount (by way of margin), both at the time they enter into futures transactions, and then on a daily basis if their positions decline in value; as a result, futures contracts are highly leveraged. Such payments are known as variation margin and are recorded by the Funds as unrealized gains or losses. Because futures markets are highly leveraged, they can be extremely volatile, and there can be no assurance that the pricing of a futures contract will correlate precisely with the pricing of the asset or index underlying it or the asset or liability of the Fund that is the subject of the hedge. It may not always be possible for a Fund to enter into a closing transaction with respect to a futures contract it has entered into, at a favorable time or price. When a Fund enters into a futures transaction, it is subject to the risk that the value of the futures contract will move in a direction unfavorable to it. When a Fund uses futures contracts for hedging purposes, it is likely that the Fund will have an asset or liability that will offset any loss (or gain) on the transactions, at least in part.

Options on Futures Contracts. If a Fund buys an option on a futures contract, it will have the right to assume a futures contract at a particular price during the course of the option. Its potential loss should generally be limited to the amount of the premium paid and any transaction costs. If a Fund sells an option on a futures contract, it is subject generally to the same risks as if it had entered into a futures contract underlying the option itself.

When a futures contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded. For information regarding the accounting treatment of options, see “Options, Rights, and Warrants” below.

Swap Agreements

Swap agreements are typically two-party contracts entered into primarily by institutional investors. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular

239

Notes to Financial Statements (Continued)

predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or “swapped” between the parties are generally calculated with respect to a “notional amount,” (i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate or in a “basket” of securities representing a particular index).

Interest Rate Swaps. When a Fund enters into an interest rate swap, it typically agrees to make payments to its counterparty based on a specified long- or short-term interest rate, and will receive payments from its counterparty based on another interest rate. Other forms of interest rate swap agreements include interest rate caps, under which, in return for a specified payment stream, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap”; interest rate floors, under which, in return for a specified payment stream, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or “floor”; and interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels. A Fund may enter into an interest rate swap in order, for example, to hedge against the effect of interest rate changes on the value of specific securities in its portfolio, or to adjust the interest rate sensitivity (duration) or the credit exposure of its portfolio overall, or otherwise as a substitute for a direct investment in debt securities.

Credit Default Swaps. A Fund also may enter into credit default swap transactions, as a “buyer” or “seller” of credit protection. In a credit default swap, one party provides what is in effect insurance against a default or other adverse credit event affecting an issuer of debt securities (typically referred to as a “reference entity”). In general, the buyer of credit protection is obligated to pay the protection seller an upfront amount or a periodic stream of payments over the term of the swap. If a “credit event” occurs, the buyer has the right to deliver to the seller bonds or other obligations of the reference entity (with a value up to the full notional value of the swap), and to receive a payment equal to the par value of the bonds or other obligations. Credit events that would trigger a request that the seller make payment are specific to each credit default swap agreement, but generally include bankruptcy, failure to pay, restructuring, acceleration, default, or repudiation/moratorium. When a Fund buys protection, it may or may not own securities of the reference entity. If it does own securities of the reference entity, the swap serves as a hedge against a decline in the value of the securities due to the occurrence of a credit event involving the issuer of the securities. If the Fund does not own securities of the reference entity, the credit default swap may be seen to create a short position in the reference entity. If a Fund is a buyer and no credit event occurs, the Fund will typically recover nothing under the swap, but will have had to pay the required upfront payment or stream of continuing payments under the swap. When a Fund sells protection under a credit default swap, the position may have the effect of creating leverage in the Fund’s portfolio through the Fund’s indirect long exposure to the issuer or securities on which the swap is written. When a Fund sells protection, it may do so either to earn additional income or to create a “synthetic” long position.

Whenever a Fund enters into a swap agreement, it takes on counterparty risk — the risk that its counterparty will be unable or unwilling to meet its obligations under the swap agreement. The Fund also takes the risk that the market will move against its position in the swap agreement. In the case of an interest rate swap, the value of the swap may increase or decrease depending on changes in interest rates. In the case of a credit default swap, the swap will become more or less valuable depending on the credit of the issuer of the underlying security, and, if a credit event occurs under a swap where the Fund is the seller of credit protection, the Fund could be required to purchase the security at par value, resulting in a significant loss to the Fund. When the Fund enters into any type of swap for hedging purposes, it is likely that the Fund will have an asset or liability that will offset any loss (or gain) on the swap, at least in part. Swap agreements may be non-transferable or otherwise highly illiquid, and a Fund may not be able to terminate or transfer a swap agreement at any particular time or at an acceptable price.

Centrally Cleared Swaps. Certain clearinghouses currently offer clearing for limited types of derivatives transactions, principally certain interest rate swaps, certain index swaps, and credit derivatives. In a cleared derivative transaction, a Fund typically enters into the transaction with a financial institution counterparty, and performance of the transaction is effectively guaranteed by a central clearinghouse, thereby reducing or eliminating the Fund’s exposure to the credit risk of its original counterparty. The Fund will be required to post amounts (“initial margin”) with the clearinghouse or at the instruction of the clearinghouse. The initial margin required by a clearinghouse may be greater than the initial margin the Fund would be required to post in an uncleared transaction. If cash is deposited as the initial margin, it is shown as collateral on a Fund’s Statement of Assets and Liabilities. Swap agreements are marked-to-market daily and subsequent payments (“variation margin”) are made or received by a Fund depending on whether unrealized gains or losses are incurred. These amounts are reflected as receivables or payables on a Fund’s Statement of Assets and Liabilities (“Variation margin on open derivative instruments”) and as a component of net change in unrealized

240

Notes to Financial Statements (Continued)

appreciation (depreciation) on a Fund’s Statement of Operations. Only a limited number of transaction types are currently eligible for clearing.

During the term of a swap transaction, changes in the value of the swap are recognized as unrealized gains or losses by marking to market to reflect the market value of the swap. When the swap is terminated, a Fund will record a realized gain or loss equal to the difference, if any, between the proceeds from (or cost of) the closing transaction and a Fund’s basis in the agreement. Upfront swap premium payments paid or received by a Fund, if any, are recorded within the value of the open swap agreement on the Fund’s Statement of Assets and Liabilities and represent payments paid or received upon entering into the swap agreement to compensate for differences between stated terms of the swap agreement and prevailing market conditions (credit spreads, currency exchange rates, and other relevant factors). These upfront payments are recorded as realized gain or loss on the Fund’s Statement of Operations upon termination or maturity of the swap agreement.

During the term of a swap transaction, the periodic net payments can be made for a set period of time or may be triggered by a predetermined credit event. The net periodic payments may be based on a fixed or variable interest rate, the change in market value of a specified security, basket of securities or index, or the return generated by a security. These periodic payments received or made by the Funds are recorded in the accompanying Statements of Operations as realized gains and losses, respectively.

** Rating is determined by Western Asset Management Company and represents a weighted average of the ratings of all securities included in the underlying index for the credit default swap. Ratings used in the weighted average are from Moody’s Investors Service, Inc., Standard & Poor’s Ratings Group, or Fitch Ratings, whichever is the highest for each constituent. All ratings are as of the report date and do not reflect subsequent changes.

† 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 Standard & Poor’s Ratings Group or Western Asset Management Company’s rating category. 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.

Options, Rights, and Warrants

A Fund may purchase and sell put and call options on securities or an index of securities to enhance investment performance or to protect against changes in market prices. A Fund that invests in debt securities may also purchase and sell put and call options to adjust the interest rate sensitivity of its portfolio or the credit exposure of the portfolio.

Call Options. A call option gives the holder the right to purchase, and obligates the writer to sell, a security at the strike price at any time before the expiration date.

Put Options. A put option gives the holder the right to sell, and obligates the writer to buy, a security at the exercise price at any time before the expiration date.

Writing put and call options. A Fund may write call options on a security it owns, in a “directional” strategy hoping to realize a greater current return through the receipt of premiums. In return for the option premium, the Fund takes the risk that it will have to forego any increase in the value of the security over the strike price. When a Fund has written a call option on a security it does not own, its exposure on such an option is theoretically unlimited. A Fund may enter into closing purchase transactions in order to realize a profit or limit a loss on a previously written call option or, in the case of a call option on a security it owns, to free itself to sell the underlying security or to write another call on the security, or protect a security from being called in an unexpected market rise. Any profits from a closing purchase transaction in the case of a call option on a security a Fund owns may be offset by a decline in the value of the underlying security. Conversely, because increases in the market price of a call option will generally reflect increases in the market price of the underlying security, any loss resulting from a closing purchase transaction relating to a call option on a security a Fund owns is likely to be offset in whole or in part by unrealized appreciation of the underlying security owned by the Fund. A Fund may not be able to close out a call option that it has previously written. A Fund may write put options in order to enhance its current return by taking a long directional position as to a security or index of securities. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then current market value, resulting in a potential capital loss unless the security later appreciates in value. A Fund may terminate a put option that it has written before it expires by entering into a closing purchase transaction. Any loss from this transaction may be partially or entirely offset by the premium received on the terminated option. A Fund may not be able to close out a put option that it has previously written.

When a Fund writes a call or put option, an amount equal to the premium received is recorded as a liability. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are added to the proceeds or offset against the amount paid on the underlying investment to determine the realized gain or loss.

Purchasing put and call options. A Fund may purchase put options to protect portfolio holdings against a decline in market value of a security or securities held by it. A Fund may also purchase a put option hoping to profit from an anticipated decline in the value of the underlying security. If the Fund holds the security underlying the option, the option premium and any transaction costs will reduce any profit the Fund might have realized had it sold the underlying security instead of buying the put option. A Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. A Fund may also purchase a call option as a long directional investment hoping to profit from an anticipated increase in the value of the underlying security. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

When a Fund purchases an option, it runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction before the option’s expiration. If the price of the

242

Notes to Financial Statements (Continued)

underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by a Fund in the underlying security, since the Fund will not realize a loss if the security’s price does not change. Premiums paid for purchasing options that expire are treated as realized losses.

Exchange Traded Options. Exchange traded options purchased or sold by a Fund may be traded on a securities or options exchange or market. Such options typically have minimal exposure to counterparty risk. However, an exchange or market may at times find it necessary to impose restrictions on particular types of options transactions, such as opening transactions. If an underlying security ceases to meet qualifications imposed by the market or the Options Clearing Corporation, new series of options on that security will no longer be opened to replace expiring series, and opening transactions in existing series may be prohibited. Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price.

OTC Options. OTC options purchased or sold by a Fund are not traded on securities or options exchanges or backed by clearinghouses. Rather, they are entered into directly between a Fund and the counterparty to the option. In the case of an OTC option purchased by the Fund, the value of the option to the Fund will depend on the willingness and ability of the option writer to perform its obligations to the Fund. In addition, OTC options may not be transferable and there may be little or no secondary market for them, so they may be considered illiquid. It may not be possible to enter into closing transactions with respect to OTC options or otherwise to terminate such options, and as a result a Fund may be required to remain obligated on an unfavorable OTC option until its expiration. OTC options are valued using prices supplied by a primary pricing source, selected pursuant to procedures approved by the Trustees.

Rights and Warrants. A Fund may purchase or hold warrants or rights in order to gain exposure to the underlying security without owning the security, including, for example, cases where the Fund hopes to lock in the price today of a security it may wish to purchase in the future. Warrants generally give the holder the right, but not the obligation, to buy a security at a stated price. In order for a warrant to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover any premium and transaction costs. Rights may similarly confer on the holder the right to purchase or acquire securities, including through participation in a so-called rights offering. Bonds may be issued with warrants or other rights attached to purchase or acquire equity or other debt securities, typically of the bond issuer. The market prices of bonds with warrants or rights attached to purchase equity securities or bonds may, to some degree, reflect changes in the values of the underlying securities.

When a Fund purchases or otherwise acquires warrants or other rights, it runs the risk that it will lose its entire investment in the warrants or rights, unless the Fund exercises the warrant or right, acquires the underlying securities, or enters into a closing transaction before expiration. If the price of the underlying security does not rise to an extent sufficient to cover any premium and transaction costs, the Fund will lose part or all of its investment. Any premiums or purchase price paid for warrants or other rights that expire are treated as realized losses. Warrants and similar rights differ from options in that they are typically written by the issuer of the security underlying the warrant or right. Although some warrants and rights may be non-transferable, others may be traded over-the-counter or on an exchange.

The Fund(s) listed in the following table had open written option contracts at March 31, 2016. A Fund’s current exposure to a counterparty is the fair value of the contract.

Inflation-Indexed Bonds

The Funds may invest in inflation-indexed bonds, which are fixed income securities whose principal value or coupon is periodically adjusted according to the rate of inflation, as measured by the Consumer Price Index for All Urban Consumers (“CPI-U”) (for U.S. Treasury inflation-indexed bonds) or, generally, by a comparable inflation index calculated by the foreign government issuing the inflation-indexed bonds.

If the periodic adjustment rate measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds, even during a period of deflation. However, the current market value of the bonds is not guaranteed, and will fluctuate. The Funds may also invest in other inflation related bonds which may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal. Any adjustments to the principal amount of an inflation-indexed bond due to inflation will be reflected as increases or decreases to interest income. Such adjustments may have a significant impact on the Fund’s distributions.

The value of inflation-indexed bonds is generally based on changes in real interest rates, which in turn are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if nominal interest rates increased at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed bonds. While the values of these securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. There can be no assurance that the CPI-U or any foreign inflation index will accurately measure the real rate of inflation, or that the rate of inflation in a foreign country will correlate to the rate of inflation in the United States. Additionally, if interest rates rise due to reasons other than inflation, investors in these securities may not be protected to the extent that the increase is not reflected in the bond’s inflation measure.

Bank Loans

Certain of the Funds may invest in bank loans including, for example, corporate loans, loan participations, direct debt, bank debt, and bridge debt. A Fund may invest in a loan by lending money to a borrower directly as part of a syndicate of lenders. In a syndicated loan, the agent that originated and structured the loan typically administers and enforces the loan on behalf of the syndicate. Failure by the agent to fulfill its obligations may delay or adversely affect receipt of payment by a Fund. A Fund may also invest in loans through novations, assignments, and participation interests. In a novation, a Fund typically assumes all of the rights of a lending institution in a loan, including the right to receive payments of principal and interest and other amounts directly from the borrower and to enforce its rights as a lender directly against the borrower. When a Fund takes an assignment of a loan, the Fund acquires some or all of the interest of another lender (or assignee) in the loan. In such cases, the Fund may be required generally to rely upon the assignor to demand payment and enforce rights under the loan. If a Fund acquires a participation in the loan, the Fund purchases an indirect interest in a loan held by a third party and the Fund typically will have a contractual relationship only with the third party loan investor, not with the borrower. As a result, a Fund may have the right to receive payments of principal, interest, and any fees to which it is entitled only from the loan investor selling the participation and only

244

Notes to Financial Statements (Continued)

upon receipt by such loan investor of such payments from the borrower. In such cases, a Fund assumes the credit risk of both the borrower and the loan investor selling the participation, and the Fund may be unable to realize some or all of the value of its interest in the loan in the event of the insolvency of the third party.

Changes in the financial condition of the borrower or economic conditions or other circumstances may reduce the capacity of the borrower to make principal and interest payments on such instruments and may lead to defaults. The value of any collateral securing a bank loan may decline after the Fund invests, and there is a risk that the value of the collateral may not be sufficient to cover the amount owed to the Fund.

At March 31, 2016, the Funds had no unfunded loan commitments.

Short Sales

A short sale is a transaction in which a Fund sells a security it does not own in anticipation that the market price of that security will decline. When a Fund makes a short sale on a security, it must borrow the security sold short and deliver it to a broker-dealer through which it made the short sale as collateral for its obligation to deliver the security upon the conclusion of the sale. A Fund may have to pay a fee to borrow particular securities and is often obligated to pay over any accrued interest and dividends on such borrowed securities. If the price of the security sold short increases between the time of the short sale and the time a Fund replaces the borrowed security, a Fund will incur a loss, which could be unlimited, in cases where a Fund is unable for whatever reason to close out its short position; conversely, if the price declines, a Fund will realize a capital gain. Any gain will be decreased, and any loss increased, by the transaction costs described above. The successful use of short selling may be adversely impacted by imperfect correlation between movements in the price of the security sold short and the securities being hedged.

Repurchase Agreements

Each Fund may enter into repurchase agreements with certain banks and broker-dealers whereby a Fund acquires a security for cash and obtains a simultaneous commitment from the seller to repurchase the security at an agreed upon price and date. A Fund, through its custodian, takes possession of the securities collateralizing the repurchase agreement in a segregated account. Repurchase agreements must be fully collateralized at all times, but involve some risk to a Fund if the other party should default on its obligation and the Fund is delayed or prevented from recovering the collateral, or if the Fund is required to return collateral to a borrower at a time when it may realize a loss on the investment of that collateral.

When-Issued, Delayed-Delivery, Forward Commitment, and To-Be-Announced Transactions

A Fund may enter into when-issued, delayed-delivery, forward commitment, or to-be-announced (“TBA”) transactions (collectively, the “Forward Transactions”) in order to lock in the purchase price of the underlying security, or in order to adjust the interest rate exposure of the Fund’s existing portfolio. In Forward Transactions, a Fund commits to purchase or sell particular securities, with payment and delivery to take place at a future date. In the case of TBA purchase commitments, the unit price and the estimated principal amount are established when the Fund enters into a commitment, with the actual principal amount being within a specified range of the estimate. Although a Fund does not typically pay for the securities in these types of transactions until they are delivered, it immediately assumes the risks of ownership, including the risk of price fluctuation. As a result, each of these types of transactions may create investment leverage in a Fund’s portfolio and increase the volatility of the Fund. If a Fund’s counterparty fails to deliver a security purchased in a Forward Transaction, there may be a loss, and the Fund may have missed an opportunity to make an alternative investment.

These securities are valued on the basis of valuations furnished by a pricing service, selected pursuant to procedures approved by the Trustees, which determines valuations taking into account appropriate factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. Securities for which no market quotation is available are valued at fair value in accordance with procedures approved by the Trustees. The Funds record on a daily basis the unrealized appreciation (depreciation) based upon changes in the values of these securities. When a Forward Transaction is closed, the Funds record a realized gain or loss equal to the difference between the value of the transaction at the time it was opened and the value of the transaction at the time it was closed.

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 qualifying U.S. and foreign 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 or securities adjusted daily to have market 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. As with other extensions of credit, the Funds may bear the risk of delay in recovery or even loss of rights in the collateral should the Borrower of the securities fail financially. 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 March 31, 2016, the Funds’ collateral was equal to or greater than 100% of the market value of securities on loan.

Security loans can be terminated at the discretion of either the lending agent or the Fund and the related securities must be returned within the earlier of the standard trade settlement period for such securities or within three business days. For all Funds, all securities on loan are classified as common stock in the Fund’s Portfolio of Investments at March 31, 2016.

The Funds employ the agent to implement their securities lending program and the agent receives a fee from the Funds for its services. In addition, the Funds may be required to pay a rebate to the Borrower. Accordingly, a Fund’s compensation for lending its securities is reduced by any such fees or rebate paid to the securities lending agent or Borrower, respectively. For the period ended March 31, 2016, the Fund(s) earned securities lending net income as follows:

	Securities Lending Gross Income		Securities Lending Fees and Expenses		Securities Lending Net Income
Large Cap Value Fund	$	89,441	$	17,992	$	71,449
Fundamental Growth Fund		3,690		746		2,944

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 gain are recorded as a reduction of cost of investments and/or as a realized gain. The Funds determine the classification of distributions received as return of capital distributions or capital gain distributions.

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.

Allocation of Operating Activity

In maintaining the records for the Funds, the income and expense accounts are allocated daily to each class of shares. Investment income and loss, and unrealized and realized gains or losses are prorated among the classes of shares based on the relative net assets of each. Expenses are allocated to each class of shares depending on the nature of the expenditures. Administration and service fees, if any, which are directly attributable to a class of shares, are charged to that class’s operations. Expenses of a Fund not directly attributable to the operations of any specific class of shares of the Fund are prorated among the classes to which the expense relates based on relative net assets.

Foreign Securities

Each of the Diversified International Fund, MSCI EAFE International Index Fund, and Overseas Fund invests substantially all of its assets in foreign securities. The other Funds may also 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, and diplomatic risks. In addition, fluctuations in currency exchange rates may adversely 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, greater price volatility, higher relative rates of inflation, greater political, economic, and social instability, greater custody and operational risks, and greater volatility in currency exchange rates.

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 (the “Code”), 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.

Net capital loss carryforwards may be applied against any net realized taxable gains in succeeding years, subject to the carryforward period limitations, where applicable. On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the “Modernization Act”) was signed by the President. The Modernization Act changed the capital loss carryforward rules as they relate to regulated investment companies. Capital losses generated in tax years beginning after the date of enactment may now be carried forward indefinitely, and retain the character of the original loss. Under pre-enactment law, capital losses could be carried forward for up to eight tax years as short-term capital losses. The provisions affecting the utilization of capital loss carryforwards under the Modernization Act also require the utilization of post-enactment losses prior to the utilization of pre-enactment losses.

At September 30, 2015, the following Fund(s) had available, for federal income tax purposes, pre-enactment unused capital losses:

	Expiring 2016		Expiring 2017		Expiring 2018
Strategic Bond Fund	$	-	$	4,220,698	$	-
Diversified Value Fund		-		3,658,831		-
Diversified International Fund		10,172,267		62,822,946		511,296
Overseas Fund		-		34,927,900		-

Net capital loss carryforwards for the Fund(s) shown in the above table are from pre-enactment years and are, therefore, subject to the eight-year carryforward period and possible expiration.

At September 30, 2015, the following Fund(s) had post-enactment accumulated capital loss carryforwards:

	Short Term Capital Loss Carryforward		Long term Capital Loss Carryforward
Strategic Bond Fund	$	-	$	1,453,115
Diversified International Fund		2,543,171		-

Net capital loss carryforwards for the Fund(s) shown in the above table are from post-enactment years and are, therefore, not subject to the eight-year carryforward period and possible expiration.

Generally accepted accounting principles in the United States of America require that only distributions in excess of tax basis earnings and profits be reported in the financial statements as a return of capital.

The tax character of distributions (including capital gain dividends, if any, designated pursuant to Section 852 of the Code) paid during the period ended September 30, 2015, was as follows:

	Ordinary Income		Long Term Capital Gain		Return of Capital
Total Return Bond Fund	$	1,318,713	$	-	$	-
Strategic Bond Fund		72,594		-		-

	Amount

Overseas Fund		786,837

Capital accounts within the financial statements are periodically adjusted for permanent differences between book and tax accounting. These adjustments have no impact on net assets or the results of operations. Temporary book and tax accounting differences will reverse in subsequent periods. At September 30, 2015, temporary book and tax accounting differences were primarily attributable to investments in forward contracts, futures contracts, options contracts, swap agreements, premium amortization accruals, defaulted bond income accruals, non-REIT return of capital outstanding, passive foreign investment companies, non-taxable dividends, the deferral of wash sale losses, and deferred Trustee compensation.

At September 30, 2015, the components of distributable earnings on a tax basis were as follows:

	Undistributed Ordinary Income		Undistributed Long Term Capital Gain (Capital Loss Carryover)			Other Temporary Differences			Unrealized Appreciation (Depreciation)
Total Return Bond Fund	$	19,964,390	$	-		$	(282,929	)	$	3,635,816

The Funds did not have any unrecognized tax benefits at March 31, 2016, nor were there any increases or decreases in unrecognized tax benefits for the period then ended. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits as an income tax expense in the Statements of Operations. During the period ended March 31, 2016, the Funds did not incur any such interest or penalties. The Funds are subject to examination by U.S. federal and state tax authorities for returns filed for the prior three fiscal years. Foreign taxes are provided for based on the Funds’ understanding of the tax rules and rates that exist in the foreign markets in which they invest.

7. Indemnifications

Under the Funds’ organizational documents, current and former Trustees and Officers are provided with specified rights to indemnification against liabilities arising in connection with the performance of their duties to the Funds, and shareholders are indemnified against personal liability for obligations of the Funds. In the normal course of business, the Funds may also enter into contracts that provide general indemnifications. The Funds’ maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Funds. The risk of material loss from such claims is considered remote.

8. New Accounting Pronouncements

In May 2015, The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2015-07, Fair Value Measurement (Topic 820): “Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)” (“ASU 2015-07”) to address the diversity in practice of how investments measured at net asset value with redemption dates in the future (including periodic redemption dates) are categorized within the fair value hierarchy. ASU 2015-07 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2015. Management is currently evaluating the implications of these changes and their impact to the financial statements.

9. Legal Proceedings

On December 7, 2010, the Trust was named as a defendant and putative member of the proposed defendant class of shareholders named in an adversary proceeding brought by The Official Committee of Unsecured Creditors of Tribune Company (the “Official Committee”) in the U.S. Bankruptcy Court for the District of Delaware, in connection with Tribune Company’s Chapter 11 bankruptcy proceeding (In re Tribune Company). The proceeding relates to a leveraged buyout (“LBO”) transaction by which Tribune Company converted to a privately-held company in 2007, and the putative defendant class is comprised of beneficial owners of shares of Tribune Company who received proceeds (the “Proceeds”) of the LBO. The Official Committee seeks to recover payments of those Proceeds.

The potential amounts sought to be recovered from the Diversified Value Fund and S&P 500 Index Fund, plus interest and the Official Committee’s court costs, are approximately $1,621,800 and $1,186,430, respectively.

In addition, on June 2, 2011, the Diversified Value Fund and S&P 500 Index Fund were named as defendants in a closely related, parallel adversary proceeding brought in connection with the Tribune Company’s LBO by Deutsche Bank Trust Company Americas, in its capacity as successor indenture trustee for a certain series of Senior Notes, Law Debenture Trust Company of New York, in its capacity as successor indenture trustee for a certain series of Senior Notes, and Wilmington Trust Company, in its

273

Notes to Financial Statements (Continued)

capacity as successor indenture trustee for the PHONES Notes (together, the “Plaintiffs”), in the United States District Court for the District of Massachusetts. The Plaintiffs also seek to recover payments of the Proceeds.

The Funds cannot predict the outcome of these proceedings. Accordingly, the Funds have not accrued any amounts related to these proceedings. If the proceedings were to be decided in a manner adverse to the Funds, or if the Funds were to enter into a settlement agreement with the Official Committee or the Plaintiffs, as applicable, the payment of such judgment or settlement could potentially have a material adverse effect on the Funds’ net asset values depending on the net assets of each applicable Fund at the time of such judgment or settlement.

10. Subsequent Events

In preparation of these financial statements, management has evaluated the events and transactions subsequent to March 31, 2016, through the date when the financial statements were issued, and determined that there are no subsequent events or transactions that would require adjustments to or disclosures in the Funds’ financial statements.

Quarterly Reporting

The Funds file their complete schedule of portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. The Funds’ Forms N-Q are available on the SEC’s EDGAR database on its website at http://www.sec.gov and may be reviewed and copied at the SEC’s Public Reference Room in Washington D.C. Information on the operation of the SEC’s Public Reference Room may be obtained by calling 1-800-SEC-0330.

Trustees’ Approval of Investment Advisory Contracts

At their meeting in November 2015, the Trustees, including the Trustees who are not “interested persons” (as such term is defined in the 1940 Act) of the Trust, MML Advisers, or subadvisers (the “Independent Trustees”), reviewed and approved a proposal to lower the advisory fee breakpoints of the Mid-Cap Value Fund, Small Cap Value Equity Fund, and Total Return Bond Fund (the “Funds”). In arriving at their decision, the Trustees considered materials provided by MML Advisers, including revised profitability schedules for the Funds. In their deliberations, the Trustees were advised by independent counsel.

The amendments to the advisory agreements for the Funds became effective on January 1, 2016.

At their meeting in November 2015, the Trustees, including the Independent Trustees, also reviewed and approved a proposal to lower the subadvisory fee paid by MML Advisers to Systematic Financial Management, L.P. (“Systematic”) for the Mid-Cap Value Fund. In arriving at their decision, the Trustees discussed the fees payable to Systematic for the Mid-Cap Value Fund by MML Advisers and the effect of such fees on the profitability to MML Advisers. The Trustees concluded that they were satisfied that MML Advisers’ projected level of profitability due to the amended subadvisory agreement was not excessive and the subadvisory fee amount under the amended subadvisory agreement was fair and reasonable. In their deliberations, the Trustees were advised by independent counsel.

The amended subadvisory agreement became effective on December 1, 2015.

At their meeting in February 2016, the Trustees, including the Independent Trustees, reviewed and approved a proposal to lower the subadvisory fee paid by MML Advisers to T. Rowe Price Associates, Inc. (“T. Rowe Price”) for the Blue Chip Growth Fund. In arriving at their decision, the Trustees discussed the fees payable to T. Rowe Price for the Blue Chip Growth Fund by MML Advisers and the effect of such fees on the profitability to MML Advisers. The Trustees concluded that they were satisfied that MML Advisers’ projected level of profitability due to the amended subadvisory agreement was not excessive and the subadvisory fee amount under the amended subadvisory agreement was fair and reasonable. In their deliberations, the Trustees were advised by independent counsel.

The amended subadvisory agreement became effective on March 1, 2016.

Prior to the votes being taken to approve the amendments to the advisory and subadvisory agreements discussed above, the Independent Trustees met separately in executive session to discuss the appropriateness of each such contract. The Independent Trustees weighed the foregoing matters in light of the advice given to them by their independent legal counsel as to the law applicable to the review of investment advisory contracts. In arriving at a decision, the Trustees, including the Independent Trustees, did not identify any single matter as all-important or controlling. The foregoing summary does not detail all of the matters considered.

Fund Expenses March 31, 2016

Expense Examples:

The following information is in regards to expenses for the six months ended March 31, 2016:

As a shareholder of the Funds, you may incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemptions; and (2) ongoing costs, including advisory fees, distribution and/or service (12b-1) fees, and other Fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds. These examples are based on an investment of $1,000 invested for the six months ended March 31, 2016.

Actual Expenses:

The first four columns of the table below provide information about actual account values and actual expenses. You may use this information, 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 under the heading entitled “Operating Expenses Incurred” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes:

The last two columns of the table below provide information about hypothetical account values and hypothetical expenses based on the 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 the 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.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs. Therefore, the last two columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

MassMutual Select BlackRock Global Allocation Fund – President’s Letter to Shareholder (Unaudited)

To Our Shareholders

Eric Wietsma

“In MassMutual’s view, retirement investors may be well served by maintaining an investment strategy that is suited to how comfortable they are with the markets’ ups and downs, how long they have to save and invest, and what their specific financial goals are.”

March 31, 2016

Welcome to the MassMutual Select BlackRock Global Allocation Fund Semiannual Report, covering the six months ended March 31, 2016. U.S. stocks, for the most part, outperformed their foreign counterparts, reflecting the ongoing strength of the U.S. economy during the period. Investors continued to closely monitor economic data releases in their vigil over the potential timing for the U.S. Federal Reserve’s (the “Fed”) long-awaited launch of interest rate increases – a source of investor speculation for most of 2015. During the reporting period, low oil prices and China’s continued economic difficulties continued to capture investors’ attention. Against this backdrop, the price of West Texas Intermediate crude oil started the period at nearly $45 per barrel and declined to nearly $37 at the end of March. This masked the extreme volatility of the commodity, however – whose price reached as high as $47.88 on November 3, 2015, and as low as $26.19 on February 11, 2016. Gasoline prices followed a similar pattern, starting out the six-month period at an average of $2.29 – before settling at $2.06 on March 31, 36 cents lower than the same time in 2015. The price of gold also fluctuated over the course of the six months, starting the period at $1,119 per ounce, before finishing the first quarter at $1,237.

Key events that characterized the period

Thanks to a robust October rally, U.S. stocks performed relatively well in the final quarter of 2015 against the backdrop of a somewhat disappointing first three quarters, when several factors had kept share prices from making much upward headway. These included weak commodity prices – especially crude oil, uncertainty about the timing of the Fed’s first interest rate hike since 2006, investor concerns about the strength and durability of the U.S. economic recovery, and worries over China and emerging markets worldwide.

After an extremely volatile third quarter of 2015, share prices recovered strongly in October, with two of the most widely followed U.S. equity benchmarks, the Dow Jones Industrial Average^SM (the “Dow”) and the S&P 500^® Index, turning in their best monthly gains since October 2011. Investor fears about China and crude oil eased, and a weak September payroll number fueled hopes that the Fed might delay raising short-term interest rates; however, the October and November employment reports were considerably stronger. This renewed talk of a rate increase – which, in fact, finally occurred at the mid-December meeting, when the Fed hiked the target range for the federal funds rate – the Fed’s overnight bank lending rate – to 0.25%-0.50% from 0%-0.25%. Elsewhere, crude oil broke to another new low for the year in December and ended 2015 with an annual decline of 31% after falling almost 50% in 2014. These factors led to choppy market action over the final two months of the year.

The U.S. economy continued to improve, although results were mixed. For example, in mid-October, several housing reports yielded generally positive results, whereas later that month, the housing outlook was muddled by new home sales figures that were the lowest since November 2014. On the other hand, there was mostly good news on the employment front, as jobless claims experienced a favorable downward trend during the fourth quarter – and first-time jobless claims dropped to a 42-year low in mid-December. This was despite the October Job Openings and Labor Turnover Survey, which in December showed a decline in job openings from 5.526 million to 5.383 million. Employment news remained largely positive, however, as even the manufacturing sector, which struggled from falling exports due to a strong dollar, posted encouraging results in the fourth quarter of 2015.

After experiencing a steep plunge and vigorous recovery as recently as August and October, respectively, U.S. stocks repeated that scenario in the first quarter of 2016. In both cases, concerns about China’s slowing economy and falling crude oil prices helped to drive weakness in share prices. Adding to these concerns at the start of 2016 was fear of slowing global and domestic economic growth, the latter underscored by initial estimates that U.S. gross domestic product (“GDP”) expanded by a disappointing 0.7% rate in the fourth quarter of 2015, although that number was subsequently revised upward.

Share prices continued to struggle early in February, as global equity markets moved roughly in tandem with the price of oil, which declined early on, but rallied later in the month on hopes that producers would curtail supply. Concerns about the European banking system also worried investors early in February. In the U.S., a weak January employment report stoked fears that a recession could be on the horizon. However, later in the quarter, upward revisions in estimated fourth-quarter U.S. economic growth, first to 1.0% and ultimately to 1.4%, helped the equity markets rebound. The employment picture also brightened, as February’s nonfarm payrolls came in significantly stronger than the previous two months’. At the same time, the payroll numbers for both January and December were revised upward.

The rally in equities continued in March, with the Fed doing its part by reassuring investors that the central bank would be cautious about implementing further hikes in short-term interest rates. Stocks ended March near their highs for the quarter and only a scant few percent off their all-time highs.

The major stock indexes in the U.S. advanced for the six months ended March 31, 2016 – largely, but not entirely – outperforming foreign developed and emerging markets. The blue-chip Dow climbed 10.07% to lead the major market indexes for the period. Next were the large-cap stock S&P 500 Index, which rose 8.49%; and the technology-heavy NASDAQ Composite^® Index, which advanced 6.07%. The Russell 2000^® Index, a benchmark of small-cap stocks, gained a much more modest 2.02% over the six months. In international markets, the MSCI EAFE Index, an indicator of foreign developed-market stocks, posted a mere 1.56% advance, while the MSCI Emerging Markets Index, a measure of the performance of emerging stock markets throughout the world, had a more impressive 6.41% return. Fixed-income investments advanced somewhat during the period, with the Barclays U.S. Aggregate Bond Index returning 2.44%.*

Notes to Consolidated Financial Statements (Unaudited)

1. The Fund

MassMutual Select Funds (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end, management investment company. The Trust is organized under the laws of the Commonwealth of Massachusetts as a Massachusetts business trust pursuant to an Agreement and Declaration of Trust dated May 28, 1993, as amended and restated as of November 21, 2011, as it may be further amended from time to time. The MassMutual Select BlackRock Global Allocation Fund (the “Fund”) is a series of the Trust.

Each share class of the Fund represents an interest in the same portfolio of assets. The principal difference among the classes is the level of service and administration fees, and shareholder and distribution service expenses borne by the classes. Because each class will have different fees and expenses, performance and share prices will vary between the classes. The classes of shares are offered to different types of investors, as outlined in the Fund’s Prospectus.

On May 13, 2015, the Board of Trustees (“Trustees”) approved a change in the fiscal year end of the Fund from December 31 to September 30. Accordingly, the Fund’s consolidated financial statements and related notes include information as of the nine month period ended September 30, 2015, and the year ended December 31, 2014.

Effective April 1, 2014, Class S shares were renamed Class R5 shares, Class Y shares were renamed Service Class shares, and Class L shares were renamed Administrative Class shares.

2. Significant Accounting Policies

The following is a summary of significant accounting policies followed consistently by the Fund in the preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“generally accepted accounting principles”). The preparation of the consolidated financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements. Actual results could differ from those estimates.

Basis of Consolidation

The accompanying consolidated financial statements for the Fund include the accounts of MassMutual Select Cayman Global Allocation Fund I, Ltd. (the “Subsidiary”), a wholly owned subsidiary of the Fund, which primarily invests in commodity-related investments consistent with the Fund’s investment objectives and policies as stated in its Prospectus and Statement of Additional Information. The Subsidiary allows the Fund to hold these commodity-related investments and still satisfy regulated investment company tax requirements. The Fund may invest up to 25% of its total assets in the Subsidiary. Intercompany accounts and transactions have been eliminated. As of March 31, 2016, the Fund’s net assets were $561,608,821, of which $14,621,856 or 2.60%, represents the Subsidiary’s net assets.

Investment Valuation

The net asset value of the 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.

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,

26

Notes to Consolidated Financial Statements (Unaudited) (Continued)

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. Restricted securities are generally valued at a discount to similar publicly traded securities.

Investments for which market quotations are not available or for which a pricing service or vendor does not provide a value, or for which such market quotations or values are considered by the investment adviser or 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) are stated at fair valuations determined in good faith by the Fund’s Valuation Committee¹ in accordance with procedures approved annually by the Board of Trustees (“Trustees”), and under the general oversight of the Trustees. The Fund’s Valuation Committee employs various methods to determine fair valuations including a regular review of significant inputs and assumptions and review of any related market activity. The Fund’s Valuation Committee reports to the Trustees at their regularly scheduled meetings. It is possible that fair value prices will be used by the Fund to a significant extent. The value determined for an investment using the Fund’s fair value procedures may differ from recent market prices for the investment and may be significantly different from the value realized upon the sale of such investment.

The Fund may invest in securities that are traded principally in foreign markets and that trade on weekends and other days when the Fund does not price its shares. As a result, the values of the Fund’s portfolio securities may change on days when the prices of the Fund’s shares are not calculated. The prices of the Fund’s shares will reflect any such changes when the prices of the Fund’s shares are next calculated, which is the next business day. The Fund 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 Fund values its 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 Fund’s 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 Fund calculates its 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.

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

¹  The Valuation Committee consists of the President, Treasurer, Assistant Treasurers, Vice Presidents (except for the CCO), Assistant Vice Presidents, Secretary, and Assistant Secretaries of the Trust, as well as such alternate members as the Trustees may from time to time designate. The Valuation Committee reviews and determines the fair valuation of portfolio securities and the Fund’s pricing procedures in general.

27

Notes to Consolidated Financial Statements (Unaudited) (Continued)

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 Fund can access at the measurement date

The types of assets and liabilities categorized in Level 1 generally include actively traded domestic and certain foreign equity securities, derivatives actively traded on a national securities exchange (such as some warrants, rights, futures, and options), and shares of open-end mutual funds.

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

The types of assets and liabilities categorized in Level 2 generally include debt securities such as U.S. Government and agency securities, mortgage-backed securities, asset-backed securities, municipal obligations, sovereign debt obligations, bank loans, corporate bonds, and those securities valued at amortized cost; OTC derivatives such as swaps, options, swaptions, and forward foreign currency exchange contracts; certain restricted securities; and non-exchange traded equity securities and certain foreign equity securities traded on particular foreign exchanges that close before the Fund determines its net asset values.

Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The types of assets and liabilities categorized in Level 3 generally include securities for which prices, spreads, or any of the other aforementioned significant inputs are unobservable. Generally, securities whose trading has been suspended or that have been de-listed from their current primary trading exchange; securities in default or bankruptcy proceedings for which there is no current market quotation; securities and certain derivatives valued by broker quotes which may include brokers’ assumptions; and any illiquid Rule 144A securities or restricted securities issued by non-public entities are categorized in Level 3.

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 Level 1, Level 2, or Level 3.

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.

The Fund characterized all securities sold short at Level 1, as of March 31, 2016. The level classification by major category of investments is the same as the category presentation in the Consolidated Portfolio of Investments.

Notes to Consolidated Financial Statements (Unaudited) (Continued)

None of the unobservable inputs, individually or collectively, had a material impact on the Fund other than those disclosed below.

The Fund fair values certain of its Level 3 investments using acquisition cost, although the transaction may not have occurred during the current reporting period. These investments are generally privately held investments, but may include defaulted securities and new debt issuances. There may not be a secondary market for such investments, and/or there are a limited number of investors. The determination to fair value such investments at cost is based upon factors consistent with the principles of fair value measurement that are reasonably available to the Valuation Committee. Valuations are reviewed by members of the Valuation Committee utilizing available market information to determine if the carrying value of these investments should be adjusted. Such market data may include, but is not limited to, observations of the trading multiples of public companies considered comparable to the private companies being valued, financial or operational information released by the company, and/or news or corporate events that affect the investment, also referred to as enterprise value (EV) to earnings before interest, taxes, depreciation, and amortization (EBITDA) ratios. Valuations may be adjusted to account for company-specific issues, the lack of liquidity inherent in a nonpublic investment and the fact that comparable public companies are not identical to the investments being fair valued by the BlackRock Global Allocation Fund. All market variables are assessed on a regular frequency and calibrated as necessary.

Derivative Instruments

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

* Represents the net amount receivable from the counterparty in the event of default.

** Represents the net amount payable to the counterparty in the event of default.

*** The amount presented here may be less than the total amount of collateral received/pledged as the net amount of derivative assets and liabilities for a counterparty cannot be less than $0.

† The amount presented here may be less than the total amount shown in the Consolidated Statement of Assets and Liabilities as some derivatives held by the counterparty are not covered within the master netting agreements.

Such agreements typically permit a single net payment in the event of default, including the bankruptcy or insolvency of the counterparty. Typically, the Fund and counterparties are not permitted to sell, re-pledge, or use the collateral they receive.

Further details regarding the derivatives and other investments held by the Fund during the period ended March 31, 2016, are discussed below.

Foreign Currency Exchange Transactions

The Fund may engage in foreign currency exchange transactions for hedging purposes in order to protect against uncertainty in the level of future foreign currency exchange rates, or for other, non-hedging purposes.

Forward Foreign Currency Contracts and Foreign Currency Options. The Fund may enter into foreign currency exchange transactions, including foreign currency forward contracts. These contracts call for the Fund to deliver in the future an amount of one currency in return for an amount of another currency, at an exchange rate determined at the time the contract is entered into. Forward contracts are private contractual arrangements and the Fund is subject to the risk that its counterparty will not, or will not be able to, perform its obligations. This type of arrangement may require the Fund to post margin. The Fund may also buy and sell options on currencies. When the Fund buys an option, its loss should generally be limited to the amount of the premium paid and any transaction costs. If the Fund sells an option on a currency, it is subject generally to the same risks as if it had entered into a forward contract with respect to that currency. The Fund may enter into foreign currency exchange transactions in order to hedge against changes in the values of the assets or liabilities denominated in one or more foreign currencies, or otherwise to increase or reduce the Fund’s exposure to various foreign currencies. The use of foreign currency exchange transactions may create investment leverage.

Notes to Consolidated Financial Statements (Unaudited) (Continued)

Whenever the Fund enters into a foreign currency exchange transaction, it is subject to the risk that the value of the transaction will move in a direction unfavorable to it. When the Fund uses the transactions for hedging purposes, it is likely that the Fund will have an asset or liability that will offset any loss (or gain) on the transactions, at least in part. If the Fund enters into foreign currency exchange transactions other than for hedging purposes (for example, seeking to profit from an anticipated change in the values of currencies by creating directional exposures in the portfolio with respect to one or more currencies), it will generally be subject to the same risks, but is less likely to have assets or liabilities that will offset any losses on the transactions. There can be no assurance that the Fund will be able to terminate any foreign currency exchange transaction prior to its maturity in order to limit its loss on the transaction.

Forward foreign currency contracts are marked to market daily and the change in their value is recorded by the Fund as an unrealized gain or loss. Forward foreign currency contracts are valued at the settlement price established through dealers or other market sources on the day which they are traded. When a forward foreign currency contract is extinguished, through delivery or offset by entering into another forward foreign currency contract, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it was extinguished or offset. The notional or contractual amounts of these instruments do not necessarily represent the amounts potentially subject to risk. The measurement of the risk associated with these instruments is meaningful only when all related and offsetting transactions and counterparty risks are considered. For information regarding the accounting treatment of options, see “Options, Rights, and Warrants” below.

Foreign Currency Swaps. The Fund may also enter into currency swaps, as an alternative to the transactions described above. Currency swaps involve the individually negotiated exchange by the Fund with another party of a series of payments in specified currencies in amounts determined pursuant to the terms of the swap agreement. For a description of risks associated with swap transactions and the accounting treatment, see “Swap Agreements” below.

The Fund had the following open forward foreign currency contracts at March 31, 2016. The Fund’s current exposure to a counterparty is the unrealized appreciation on the contract.

Futures Contracts

The Fund may seek to manage a variety of different risks, such as interest rate risk, equity price risk, and currency risk, through the use of futures contracts. The Fund may use interest rate futures contracts to adjust the interest rate sensitivity (duration) of its portfolio or the credit exposure of the portfolio. Interest rate futures contracts obligate the long or short holder to take or make delivery of a specified quantity of a financial instrument, such as a specific fixed-income security, during a specified future period at a specified price. The Fund may use index futures to hedge against broad market risks to its portfolio or to gain broad market exposure when it holds uninvested cash or as an inexpensive substitute for cash investments directly in securities or other assets. Securities index futures contracts are contracts to buy or sell units of a securities index at a specified future date at a price agreed upon when the contract is made and are settled in cash. Positions in futures may be closed out only on an exchange or board of trade which provides a secondary market for such futures. Because futures contracts are exchange-traded, they typically have minimal exposure to counterparty risk.

Parties to a futures contract are not required to post the entire notional amount of the contract, but rather a small percentage of that amount (by way of margin), both at the time they enter into futures transactions, and then on a daily basis if their positions decline in value; as a result, futures contracts are highly leveraged. Such payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. Because futures markets are highly leveraged, they can be extremely volatile, and there can be no assurance that the pricing of a futures contract will correlate precisely with the pricing of the asset or index underlying it or the asset or liability of the Fund that is the subject of the hedge. It may not always be possible for the Fund to enter into a closing transaction with respect to a futures contract it has entered into, at a favorable time or price. When the Fund enters into a futures transaction, it is subject to the risk that the value of the futures contract will move in a direction unfavorable to it. When the Fund uses futures contracts for hedging purposes, it is likely that the Fund will have an asset or liability that will offset any loss (or gain) on the transactions, at least in part.

When a futures contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded.

Swap Agreements

Swap agreements are typically two-party contracts entered into primarily by institutional investors. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or “swapped” between the parties are generally calculated with respect to a “notional amount,” (i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate or in a “basket” of securities representing a particular index).

Interest Rate Swaps. When the Fund enters into an interest rate swap, it typically agrees to make payments to its counterparty based on a specified long- or short-term interest rate, and will receive payments from its counterparty based on another interest rate. Other forms of interest rate swap agreements include interest rate caps, under which, in return for a specified payment stream, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap”; interest rate floors, under which, in return for a specified payment stream, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or “floor”; and interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels. The Fund may enter into an interest rate swap in order, for example, to hedge against the effect of interest rate changes on the value of specific securities in its portfolio, or to adjust the interest rate sensitivity (duration) or the credit exposure of its portfolio overall, or otherwise as a substitute for a direct investment in debt securities.

Total Return Swaps. The Fund also may enter into total return swaps. In a total return swap, one party typically agrees to pay to the other a short-term interest rate in return for a payment at one or more times in the future based on the increase in the value of an underlying security or other asset, or index of securities or assets; if the underlying security, asset, or index declines in value, the party that pays the short-term interest rate must also pay to its counterparty a payment based on the amount of the decline. The Fund may take either side of such a swap, and so may take a long or short position in the underlying security, asset, or index. The Fund may enter into a total return swap to hedge against an exposure in its portfolio — such as interest rate risk (including to adjust the duration or credit quality of the Fund’s bond portfolio), equity risk, or credit risk — or generally to put cash to work efficiently in the markets in anticipation of, or as a replacement for, cash investments. The Fund may also enter into a total return swap to gain exposure to securities or markets in which it might not be able to invest directly (in so-called market access transactions).

Credit Default Swaps. The Fund also may enter into credit default swap transactions, as a “buyer” or “seller” of credit protection. In a credit default swap, one party provides what is in effect insurance against a default or other adverse credit event affecting an issuer of debt securities (typically referred to as a “reference entity”). In general, the buyer of credit protection is obligated to pay the protection seller an upfront amount or a periodic stream of payments over the term of the swap. If a “credit event” occurs, the buyer has the right to deliver to the seller bonds or other obligations of the reference entity (with a value up to the full notional value of the swap), and to receive a payment equal to the par value of the bonds or other obligations. Credit events that would trigger a request that the seller make payment are specific to each credit default swap agreement, but generally include bankruptcy, failure to pay, restructuring, acceleration, default, or repudiation/moratorium. When the Fund buys protection, it may or may not

40

Notes to Consolidated Financial Statements (Unaudited) (Continued)

own securities of the reference entity. If it does own securities of the reference entity, the swap serves as a hedge against a decline in the value of the securities due to the occurrence of a credit event involving the issuer of the securities. If the Fund does not own securities of the reference entity, the credit default swap may be seen to create a short position in the reference entity. If the Fund is a buyer and no credit event occurs, the Fund will typically recover nothing under the swap, but will have had to pay the required upfront payment or stream of continuing payments under the swap. When the Fund sells protection under a credit default swap, the position may have the effect of creating leverage in the Fund’s portfolio through the Fund’s indirect long exposure to the issuer or securities on which the swap is written. When the Fund sells protection, it may do so either to earn additional income or to create a “synthetic” long position.

Whenever the Fund enters into a swap agreement, it takes on counterparty risk — the risk that its counterparty will be unable or unwilling to meet its obligations under the swap agreement. The Fund also takes the risk that the market will move against its position in the swap agreement. In the case of an interest rate swap, the value of the swap may increase or decrease depending on changes in interest rates. In the case of a total return swap, the swap will change in value depending on the change in value of the asset or index on which the swap is written. In the case of a credit default swap, the swap will become more or less valuable depending on the credit of the issuer of the underlying security, and, if a credit event occurs under a swap where the Fund is the seller of credit protection, the Fund could be required to purchase the security at par value, resulting in a significant loss to the Fund. When the Fund enters into any type of swap for hedging purposes, it is likely that the Fund will have an asset or liability that will offset any loss (or gain) on the swap, at least in part. Swap agreements may be non-transferable or otherwise highly illiquid, and the Fund may not be able to terminate or transfer a swap agreement at any particular time or at an acceptable price.

Swaptions. The Fund may also enter into options on swap agreements (“swaptions”). A swaption is a contract that gives a counterparty the right (but not the obligation) to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement, at some designated future time on specified terms. The Fund may write (sell) and purchase put and call swaptions. Depending on the terms of the particular option agreement, the Fund will generally incur a greater degree of risk when it writes a swaption than it will incur when it purchases a swaption. When the Fund purchases a swaption, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a swaption, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement. The Fund may enter into swaptions for the same purposes as swaps. For information regarding the accounting treatment of options, see “Options, Rights, and Warrants” below.

Centrally Cleared Swaps. Certain clearinghouses currently offer clearing for limited types of derivatives transactions, principally certain interest rate swaps, certain index swaps, and credit derivatives. In a cleared derivative transaction, the Fund typically enters into the transaction with a financial institution counterparty, and performance of the transaction is effectively guaranteed by a central clearinghouse, thereby reducing or eliminating the Fund’s exposure to the credit risk of its original counterparty. The Fund will be required to post amounts (“initial margin”) with the clearinghouse or at the instruction of the clearinghouse. The initial margin required by a clearinghouse may be greater than the initial margin the Fund would be required to post in an uncleared transaction. If cash is deposited as the initial margin, it is shown as collateral on the Fund’s Consolidated Statement of Assets and Liabilities. Swap agreements are marked-to-market daily and subsequent payments (“variation margin”) are made or received by the Fund depending on whether unrealized gains or losses are incurred. These amounts are reflected as receivables or payables on the Fund’s Consolidated Statement of Assets and Liabilities (“Variation margin on open derivative instruments”) and as a component of net change in unrealized appreciation (depreciation) on the Fund’s Consolidated Statement of Operations. Only a limited number of transaction types are currently eligible for clearing.

During the term of a swap transaction, changes in the value of the swap are recognized as unrealized gains or losses by marking to market to reflect the market value of the swap. When the swap is terminated, the Fund will record a realized gain or loss equal to the difference, if any, between the proceeds from (or cost of) the closing transaction and the Fund’s basis in the agreement. Upfront swap premium payments paid or received by the Fund, if any, are recorded within the value of the open swap agreement on the Fund’s Consolidated Statement of Assets and Liabilities and represent payments paid or received upon entering into the swap agreement to compensate for differences between stated terms of the swap agreement and prevailing market conditions (credit spreads, currency exchange rates, and other relevant factors). These upfront payments are recorded as realized gain or loss on the Fund’s Consolidated Statement of Operations upon termination or maturity of the swap agreement.

During the term of a swap transaction, the periodic net payments can be made for a set period of time or may be triggered by a predetermined credit event. The net periodic payments may be based on a fixed or variable interest rate, the change in market value

41

Notes to Consolidated Financial Statements (Unaudited) (Continued)

of a specified security, basket of securities or index, or the return generated by a security. These periodic payments received or made by the Fund are recorded in the accompanying Consolidated Statement of Operations as realized gains and losses, respectively.

† 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 Standard & Poor’s Ratings Group, rating category. 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.

Options, Rights, and Warrants

The Fund may purchase and sell put and call options on securities or an index of securities to enhance investment performance or to protect against changes in market prices. The Fund may also purchase and sell put and call options to adjust the interest rate sensitivity of its portfolio of debt securities or the credit exposure of the portfolio.

Call Options. A call option gives the holder the right to purchase, and obligates the writer to sell, a security at the strike price at any time before the expiration date.

Put Options. A put option gives the holder the right to sell, and obligates the writer to buy, a security at the exercise price at any time before the expiration date.

Writing put and call options. The Fund may write call options on a security it owns, in a “directional” strategy hoping to realize a greater current return through the receipt of premiums. In return for the option premium, the Fund takes the risk that it will have to forego any increase in the value of the security over the strike price. When the Fund has written a call option on a security it does not own, its exposure on such an option is theoretically unlimited. The Fund may enter into closing purchase transactions in order to realize a profit or limit a loss on a previously written call option or, in the case of a call option on a security it owns, to free itself to sell the underlying security or to write another call on the security, or protect a security from being called in an unexpected market rise. Any profits from a closing purchase transaction in the case of a call option on a security the Fund owns may be offset by a decline in the value of the underlying security. Conversely, because increases in the market price of a call option will generally reflect increases in the market price of the underlying security, any loss resulting from a closing purchase transaction relating to a call option on a security the Fund owns is likely to be offset in whole or in part by unrealized appreciation of the underlying security owned by the Fund. The Fund may not be able to close out a call option that it has previously written. The Fund may write put options in order to enhance its current return by taking a long directional position as to a security or index of securities. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then current market value, resulting in a potential capital loss unless the security later appreciates in value. The Fund may terminate a put option that it has written before it expires by entering into a closing purchase transaction. Any loss from this transaction may be partially or entirely offset by the premium received on the terminated option. The Fund may not be able to close out a put option that it has previously written.

43

Notes to Consolidated Financial Statements (Unaudited) (Continued)

When the Fund writes a call or put option, an amount equal to the premium received is recorded as a liability. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are added to the proceeds or offset against the amount paid on the underlying investment to determine the realized gain or loss.

Purchasing put and call options. The Fund may purchase put options to protect portfolio holdings against a decline in market value of a security or securities held by it. The Fund may also purchase a put option hoping to profit from an anticipated decline in the value of the underlying security. If the Fund holds the security underlying the option, the option premium and any transaction costs will reduce any profit the Fund might have realized had it sold the underlying security instead of buying the put option. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. The Fund may also purchase a call option as a long directional investment hoping to profit from an anticipated increase in the value of the underlying security. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

When the Fund purchases an option, it runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction before the option’s expiration. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying security, since the Fund will not realize a loss if the security’s price does not change. Premiums paid for purchasing options that expire are treated as realized losses.

Exchange Traded Options. Exchange traded options purchased or sold by the Fund may be traded on a securities or options exchange or market. Such options typically have minimal exposure to counterparty risk. However, an exchange or market may at times find it necessary to impose restrictions on particular types of options transactions, such as opening transactions. If an underlying security ceases to meet qualifications imposed by the market or the Options Clearing Corporation, new series of options on that security will no longer be opened to replace expiring series, and opening transactions in existing series may be prohibited. Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price.

OTC Options. OTC options purchased or sold by the Fund are not traded on securities or options exchanges or backed by clearinghouses. Rather, they are entered into directly between the Fund and the counterparty to the option. In the case of an OTC option purchased by the Fund, the value of the option to the Fund will depend on the willingness and ability of the option writer to perform its obligations to the Fund. In addition, OTC options may not be transferable and there may be little or no secondary market for them, so they may be considered illiquid. It may not be possible to enter into closing transactions with respect to OTC options or otherwise to terminate such options, and as a result the Fund may be required to remain obligated on an unfavorable OTC option until its expiration. OTC options are valued using prices supplied by a primary pricing source, selected pursuant to procedures approved by the Trustees.

Rights and Warrants. The Fund may purchase or hold warrants or rights in order to gain exposure to the underlying security without owning the security, including, for example, cases where the Fund hopes to lock in the price today of a security it may wish to purchase in the future. Warrants generally give the holder the right, but not the obligation, to buy a security at a stated price. In order for a warrant to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover any premium and transaction costs. Rights may similarly confer on the holder the right to purchase or acquire securities, including through participation in a so-called rights offering. Bonds may be issued with warrants or other rights attached to purchase or acquire equity or other debt securities, typically of the bond issuer. The market prices of bonds with warrants or rights attached to purchase equity securities or bonds may, to some degree, reflect changes in the values of the underlying securities.

When the Fund purchases or otherwise acquires warrants or other rights, it runs the risk that it will lose its entire investment in the warrants or rights, unless the Fund exercises the warrant or right, acquires the underlying securities, or enters into a closing transaction before expiration. If the price of the underlying security does not rise to an extent sufficient to cover any premium and transaction costs, the Fund will lose part or all of its investment. Any premiums or purchase price paid for warrants or other rights that expire are treated as realized losses. Warrants and similar rights differ from options in that they are typically written by the

44

Notes to Consolidated Financial Statements (Unaudited) (Continued)

issuer of the security underlying the warrant or right. Although some warrants and rights may be non-transferable, others may be traded over-the-counter or on an exchange.

Inflation-Indexed Bonds

The Fund may invest in inflation-indexed bonds, which are fixed income securities whose principal value or coupon is periodically adjusted according to the rate of inflation, as measured by the Consumer Price Index for All Urban Consumers (“CPI-U”) (for U.S. Treasury inflation-indexed bonds) or, generally, by a comparable inflation index calculated by the foreign government issuing the inflation-indexed bonds.

If the periodic adjustment rate measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds, even during a period of deflation. However, the current market value of the bonds is not guaranteed, and will fluctuate. The Fund may also invest in other inflation related bonds which may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal. Any adjustments to the principal amount of an inflation-indexed bond due to inflation will be reflected as increases or decreases to interest income. Such adjustments may have a significant impact on the Fund’s distributions.

The value of inflation-indexed bonds is generally based on changes in real interest rates, which in turn are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if nominal interest rates increased at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed bonds. While the values of these securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. There can be no assurance that the CPI-U or any foreign inflation index will accurately measure the real rate of inflation, or that the rate of inflation in a foreign country will correlate to the rate of inflation in the United States. Additionally, if interest rates rise due to reasons other than inflation, investors in these securities may not be protected to the extent that the increase is not reflected in the bond’s inflation measure.

Bank Loans

The Fund may invest in bank loans including, for example, corporate loans, loan participations, direct debt, bank debt, and bridge debt. The Fund may invest in a loan by lending money to a borrower directly as part of a syndicate of lenders. In a syndicated loan, the agent

46

Notes to Consolidated Financial Statements (Unaudited) (Continued)

that originated and structured the loan typically administers and enforces the loan on behalf of the syndicate. Failure by the agent to fulfill its obligations may delay or adversely affect receipt of payment by the Fund. The Fund may also invest in loans through novations, assignments, and participation interests. In a novation, the Fund typically assumes all of the rights of a lending institution in a loan, including the right to receive payments of principal and interest and other amounts directly from the borrower and to enforce its rights as a lender directly against the borrower. When the Fund takes an assignment of a loan, the Fund acquires some or all of the interest of another lender (or assignee) in the loan. In such cases, the Fund may be required generally to rely upon the assignor to demand payment and enforce rights under the loan. If the Fund acquires a participation in the loan, the Fund purchases an indirect interest in a loan held by a third party and the Fund typically will have a contractual relationship only with the third party loan investor, not with the borrower. As a result, the Fund may have the right to receive payments of principal, interest, and any fees to which it is entitled only from the loan investor selling the participation and only upon receipt by such loan investor of such payments from the borrower. In such cases, the Fund assumes the credit risk of both the borrower and the loan investor selling the participation, and the Fund may be unable to realize some or all of the value of its interest in the loan in the event of the insolvency of the third party.

Changes in the financial condition of the borrower or economic conditions or other circumstances may reduce the capacity of the borrower to make principal and interest payments on such instruments and may lead to defaults. The value of any collateral securing a bank loan may decline after the Fund invests, and there is a risk that the value of the collateral may not be sufficient to cover the amount owed to the Fund.

At March 31, 2016, the Fund had no unfunded loan commitments.

Short Sales

A short sale is a transaction in which the Fund sells a security it does not own in anticipation that the market price of that security will decline. When the Fund makes a short sale on a security, it must borrow the security sold short and deliver it to a broker-dealer through which it made the short sale as collateral for its obligation to deliver the security upon the conclusion of the sale. The Fund may have to pay a fee to borrow particular securities and is often obligated to pay over any accrued interest and dividends on such borrowed securities. If the price of the security sold short increases between the time of the short sale and the time the Fund replaces the borrowed security, the Fund will incur a loss, which could be unlimited, in cases where the Fund is unable for whatever reason to close out its short position; conversely, if the price declines, the Fund will realize a capital gain. Any gain will be decreased, and any loss increased, by the transaction costs described above. The successful use of short selling may be adversely impacted by imperfect correlation between movements in the price of the security sold short and the securities being hedged.

When-Issued, Delayed-Delivery, Forward Commitment, and To-Be-Announced Transactions

The Fund may enter into when-issued, delayed-delivery, forward commitment, or to-be-announced (“TBA”) transactions (collectively, the “Forward Transactions”) in order to lock in the purchase price of the underlying security, or in order to adjust the interest rate exposure of the Fund’s existing portfolio. In Forward Transactions, the Fund commits to purchase or sell particular securities, with payment and delivery to take place at a future date. In the case of TBA purchase commitments, the unit price and the estimated principal amount are established when the Fund enters into a commitment, with the actual principal amount being within a specified range of the estimate. Although the Fund does not typically pay for the securities in these types of transactions until they are delivered, it immediately assumes the risks of ownership, including the risk of price fluctuation. As a result, each of these types of transactions may create investment leverage in the Fund’s portfolio and increase the volatility of the Fund. If the Fund’s counterparty fails to deliver a security purchased in a Forward Transaction, there may be a loss, and the Fund may have missed an opportunity to make an alternative investment.

These securities are valued on the basis of valuations furnished by a pricing service, selected pursuant to procedures approved by the Trustees, which determines valuations taking into account appropriate factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. Securities for which no market quotation is available are valued at fair value in accordance with procedures approved by the Trustees. The Fund records on a daily basis the unrealized appreciation (depreciation) based upon changes in the values of these securities. When a Forward Transaction is closed, the Fund records a realized gain or loss equal to the difference between the value of the transaction at the time it was opened and the value of the transaction at the time it was closed.

47

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 and dividend expense are 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 gain are recorded as a reduction of cost of investments and/or as a realized gain. The Fund determines the classification of distributions received as return of capital distributions or capital gain distributions.

Foreign Currency Translation

The books and records of the Fund 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 Fund does 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 Fund and the amount actually received.

Allocation of Operating Activity

In maintaining the records for the Fund, the income and expense accounts are allocated daily to each class of shares. Investment income and loss, and unrealized and realized gains or losses are prorated among the classes of shares based on the relative net assets of each. Expenses are allocated to each class of shares depending on the nature of the expenditures. Administration and service fees, if any, which are directly attributable to a class of shares, are charged to that class’s operations. Expenses of the Fund not directly attributable to the operations of any specific class of shares of the Fund are prorated among the classes to which the expense relates based on relative net assets.

Foreign Securities

The Fund invests a significant amount of its assets 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, and diplomatic risks. In addition, fluctuations in currency exchange rates may adversely affect the values of foreign securities and the price of the Fund’s shares. Emerging markets securities are subject to greater risks than securities issued in developed foreign markets, including less liquidity, greater price volatility, higher relative rates of inflation, greater political, economic, and social instability, greater custody and operational risks, and greater volatility in currency exchange rates.

Federal Income Tax

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

The Subsidiary is classified as a controlled foreign corporation under the Code. Therefore, the Fund is required to increase its taxable income by its share of the Subsidiary’s income. Net losses of the Subsidiary cannot be deducted by the Fund in the current period nor carried forward to offset taxable income in future periods.

48

Notes to Consolidated Financial Statements (Unaudited) (Continued)

Dividends and Distributions to Shareholders

Dividends from net investment income and distributions of any net realized capital gains of the 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. Advisory Fee and Other Transactions

Investment Advisory Fee and Investment Subadviser

MML Investment Advisers, LLC (“MML Advisers”), a wholly-owned subsidiary of Massachusetts Mutual Life Insurance Company (“MassMutual”), serves as investment adviser to the Fund. Under an investment advisory agreement between MML Advisers and the Trust on behalf of the Fund, MML Advisers is responsible for providing investment management services for the Fund. In return for these services, MML Advisers receives an advisory fee, based upon the Fund’s average daily net assets, at the annual rate of 0.78% on the first $750 million; and 0.73% on any excess over $750 million.

MML Advisers has also entered into an investment subadvisory agreement with the unaffiliated investment subadviser, BlackRock Investment Management, LLC (“BlackRock”). MML Advisers pays a subadvisory fee to this subadviser based upon the average daily net assets of the Fund.

The Fund’s subadvisory fee is paid by MML Advisers out of the advisory fee previously disclosed above.

BlackRock provides investment advisory services to the Subsidiary pursuant to an investment advisory agreement. The Subsidiary pays an advisory fee to BlackRock based upon the Subsidiary’s average daily net assets. The rate of this fee is equal to the subadvisory fee rate that MML Advisers pays BlackRock in respect to the Fund. The amount of the fee payable by MML Advisers to BlackRock in respect to the Fund for any period is reduced by the amount of the advisory fee payable by the Subsidiary to BlackRock for that period. Under the Fund’s investment advisory agreement, the amount of the advisory fee payable by the Fund to MML Advisers in respect to any period is also reduced by the amount of the advisory fee payable by the Subsidiary to BlackRock in respect to that period. The amount of the reduction to the Fund’s advisory fee is reflected within expenses waived on the Consolidated Statement of Operations.

Administration Fees

Under an Administrative and Shareholder Services Agreement between the Trust and MML Advisers, on behalf of the Fund, MML Advisers is obligated to provide certain administrative and shareholder services. In return for these services, MML Advisers receives an administrative services fee, based upon the average daily net assets of the applicable class of shares of the Fund, at the following annual rates:

Class I	Class R5	Service Class	Administrative Class	Class A	Class R4	Class R3
None	0.10%	0.15%	0.15%	0.15%	0.20%	0.20%

The Subsidiary also pays certain other expenses, including administrative, accounting services, custodian, and transfer agent fees. In respect to certain (but not all) of these fees, the Fund has entered into offsetting arrangements with its service providers which result in a reduction of certain of the Fund’s expenses with respect to those assets held by the Subsidiary. Certain of these reductions are reflected within expenses waived on the Consolidated Statement of Operations.

49

Notes to Consolidated Financial Statements (Unaudited) (Continued)

Distribution and Service Fees

MML Distributors, LLC (the “Distributor”) acts as distributor to the Fund. Pursuant to a 12b-1 Plan adopted by the Trust, Class A shares and Class R4 shares of the Fund pay an annual fee of 0.25% of the average daily net assets of the class; and Class R3 shares of the Fund pay an annual fee of 0.50% of the average daily net assets of the class, to the Distributor. Such payments compensate the Distributor for services provided and expenses incurred by it for purposes of promoting the sale of the relevant class of shares, reducing redemptions of shares, or maintaining or improving services provided to the Fund’s shareholders. The Distributor is a wholly-owned subsidiary of MassMutual.

The Trust has entered into a separate Supplemental Shareholder Services Agreement with MassMutual, on behalf of Service Class shares, Administrative Class shares, and Class A shares of the Fund. Fees payable under the Supplemental Shareholder Services Agreement are intended to compensate MassMutual for its provision of shareholder services to the Fund’s investors and are calculated and paid based on the average daily net assets attributable to the relevant share classes of the Fund separately, at the following annual rates: 0.05% for Service Class shares, and 0.15% for Administrative Class shares and Class A shares. MassMutual may pay these fees to other intermediaries for providing shareholder services to the Fund’s investors.

Expense Caps and Waivers

MML Advisers has agreed to cap the fees and expenses of the Fund (other than extraordinary litigation and legal expenses, interest expense, short sale dividend and loan expense, Acquired Fund Fees and Expenses^#, or other non-recurring or unusual expenses such as organizational expenses and shareholder meeting expenses) through January 31, 2017 based upon the average daily net assets of the applicable class of shares of the Fund, as follows:

Class I	Class R5	Service Class	Administrative Class	Class A	Class R4	Class R3
0.79%	0.89%	0.99%	1.09%	1.34%	1.24%	1.49%

# Acquired Fund Fees and Expenses are borne indirectly by the Fund through investments in other pooled investment vehicles.

Expense caps and waiver amounts are reflected as a reduction of expenses on the Consolidated Statement of Operations.

Rebated Brokerage Commissions

The Fund has entered into agreements with certain brokers whereby the brokers will rebate to the Fund, in cash, a portion of brokerage commissions. Rebated brokerage commissions are amounts earned by the Fund and are included with realized gain or loss on investment transactions presented in the Consolidated Statement of Operations. For the period ended March 31, 2016, there were no brokerage commissions rebated under these agreements.

Deferred Compensation

Trustees of the Fund who are not officers or employees of MassMutual may elect to defer receipt of their annual fees in accordance with terms of a Non-Qualified Deferred Compensation Plan. Amounts deferred shall accrue interest or earnings and shall be recorded on the Fund’s books as other liabilities. Deferred compensation is included within Trustees’ fees and expenses in the Consolidated Statement of Assets and Liabilities.

Other

Certain officers and trustees of the Fund are also employees of MassMutual. The compensation of each trustee who is not an employee of MassMutual is borne by the Fund.

The beneficial ownership of the Fund’s shares by affiliated parties at March 31, 2016 was 9.8%.

The Distributor receives all contingent deferred sales charges. There were no contingent deferred sales charges imposed during the period ended March 31, 2016.

6. Federal Income Tax Information

At March 31, 2016, the cost of securities and the unrealized appreciation (depreciation) in the value of investments owned by the Fund, as computed on a federal income tax basis, were as follows:

Federal Income Tax Cost	Tax Basis Unrealized Appreciation	Tax Basis Unrealized (Depreciation)	Net Unrealized Appreciation (Depreciation)
$578,389,931	$31,055,733	$(39,376,310)	$(8,320,577)

Net capital loss carryforwards may be applied against any net realized taxable gains in succeeding years, subject to the carryforward period limitations, where applicable. On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the “Modernization Act”) was signed by the President. The Modernization Act changed the capital loss carryforward rules as they relate to regulated investment companies. Capital losses generated in tax years beginning after the date of enactment may now be carried forward indefinitely, and retain the character of the original loss. Under pre-enactment law, capital losses could be carried forward for up to eight tax years as short-term capital losses. The provisions affecting the utilization of capital loss carryforwards under the Modernization Act also require the utilization of post-enactment losses prior to the utilization of pre-enactment losses.

Generally accepted accounting principles in the United States of America require that only distributions in excess of tax basis earnings and profits be reported in the consolidated financial statements as a return of capital.

The tax character of distributions (including capital gain dividends, if any, designated pursuant to Section 852 of the Code) paid during the period ended September 30, 2015, was as follows:

Ordinary Income	Long Term Capital Gain	Return of Capital
$4,745,118	$10,685,699	$        -

Capital accounts within the consolidated financial statements are periodically adjusted for permanent differences between book and tax accounting. These adjustments have no impact on net assets or the results of operations. Temporary book and tax accounting differences will reverse in subsequent periods. At September 30, 2015, temporary book and tax accounting differences were

52

Notes to Consolidated Financial Statements (Unaudited) (Continued)

primarily attributable to investments in forward contracts, futures contracts, swap agreements, premium amortization accruals, passive foreign investment companies, non-taxable dividends, defaulted bond accruals the deferral of wash sale losses, and deferred Trustee compensation.

At September 30, 2015, the components of distributable earnings on a tax basis were as follows:

Undistributed Ordinary Income	Undistributed Long Term Capital Gain (Capital Loss Carryover)	Other Temporary Differences)	Unrealized Appreciation (Depreciation)
$9,817,530	$29,033,683	$(93,855)	$(37,639,898)

The Fund did not have any unrecognized tax benefits at March 31, 2016, nor were there any increases or decreases in unrecognized tax benefits for the period then ended. The Fund recognizes interest and penalties, if any, related to unrecognized tax benefits as an income tax expense in the Consolidated Statement of Operations. During the period ended March 31, 2016, the Fund did not incur any such interest or penalties. The Fund is subject to examination by U.S. federal and state tax authorities for returns filed for the prior three fiscal years. Foreign taxes are provided for based on the Fund’s understanding of the tax rules and rates that exist in the foreign markets in which it invests.

7. Indemnifications

Under the Fund’s organizational documents, current and former Trustees and Officers are provided with specified rights to indemnification against liabilities arising in connection with the performance of their duties to the Fund, and shareholders are indemnified against personal liability for obligations of the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund’s maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

8. New Accounting Pronouncements

In May 2015, The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2015-07, Fair Value Measurement (Topic 820): “Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)” (“ASU 2015-07”) to address the diversity in practice of how investments measured at net asset value with redemption dates in the future (including periodic redemption dates) are categorized within the fair value hierarchy. ASU 2015-07 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2015. Management is currently evaluating the implications of these changes and their impact to the consolidated financial statements.

9. Subsequent Events

In preparation of these consolidated financial statements, management has evaluated the events and transactions subsequent to March 31, 2016, through the date when the consolidated financial statements were issued, and determined that there are no subsequent events or transactions that would require adjustments to or disclosures in the Fund’s consolidated financial statements.

Fund Expenses March 31, 2016

Expense Examples:

The following information is in regards to expenses for the six months ended March 31, 2016:

As a shareholder of the Fund, you may incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemptions; and (2) ongoing costs, including advisory fees, distribution and/or service (12b-1) fees, and other Fund expenses. These examples are 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. These examples are based on an investment of $1,000 invested for the six months ended March 31, 2016.

Actual Expenses:

The first four columns of the table below provide information about actual account values and actual expenses. You may use this information, 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 under the heading entitled “Operating Expenses Incurred” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes:

The last two columns of the table below provide information about hypothetical account values and hypothetical expenses based on the 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 the 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.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs. Therefore, the last two columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Value		Annualized Expense Ratio			Ending Value (Based on Actual Returns and Expenses)		Operating Expenses Incurred*		Ending Value (Based on Hypothetical Returns and Expenses)		Operating Expenses Incurred*
Class I	$	1,000		0.80	%	$	1,022.80	$	4.05	$	1,021.00	$	4.04
Class R5		1,000		0.90	%		1,022.40		4.55		1,020.50		4.55
Service Class		1,000		1.00	%		1,022.60		5.06		1,020.00		5.05
Administrative Class		1,000		1.10	%		1,022.20		5.56		1,019.50		5.55
Class A		1,000		1.35	%		1,020.40		6.82		1,018.30		6.81
Class R4		1,000		1.25	%		1,021.00		6.32		1,018.80		6.31
Class R3		1,000		1.50	%		1,020.10		7.58		1,017.50		7.57

* Expenses are calculated using the annualized expense ratio for the six months ended March 31, 2016, multiplied by the average account value over the period, multiplied by 183 days in the period, divided by 366 days in the year, unless stated otherwise.

MassMutual RetireSMART^SM Funds – President’s Letter to Shareholders (Unaudited)

To Our Shareholders

Eric Wietsma

“In MassMutual’s view, retirement investors may be well served by maintaining an investment strategy that is suited to how comfortable they are with the markets’ ups and downs, how long they have to save and invest, and what their specific financial goals are.”

March 31, 2016

Welcome to the MassMutual RetireSMART^SM Funds Series of the MassMutual Select Funds Semiannual Report, covering the six months ended March 31, 2016. U.S. stocks, for the most part, outperformed their foreign counterparts, reflecting the ongoing strength of the U.S. economy during the period. Investors continued to closely monitor economic data releases in their vigil over the potential timing for the U.S. Federal Reserve’s (the “Fed”) long-awaited launch of interest rate increases – a source of investor speculation for most of 2015. During the reporting period, low oil prices and China’s continued economic difficulties continued to capture investors’ attention. Against this backdrop, the price of West Texas Intermediate crude oil started the period at nearly $45 per barrel and declined to nearly $37 at the end of March. This masked the extreme volatility of the commodity, however – whose price reached as high as $47.88 on November 3, 2015, and as low as $26.19 on February 11, 2016. Gasoline prices followed a similar pattern, starting out the six-month period at an average of $2.29 – before settling at $2.06 on March 31, 36 cents lower than the same time in 2015. The price of gold also fluctuated over the course of the six months, starting the period at $1,119 per ounce, before finishing the first quarter at $1,237.

Key events that characterized the period

Thanks to a robust October rally, U.S. stocks performed relatively well in the final quarter of 2015 against the backdrop of a somewhat disappointing first three quarters, when several factors had kept share prices from making much upward headway. These included weak commodity prices – especially crude oil, uncertainty about the timing of the Fed’s first interest rate hike since 2006, investor concerns about the strength and durability of the U.S. economic recovery, and worries over China and emerging markets worldwide.

After an extremely volatile third quarter of 2015, share prices recovered strongly in October, with two of the most widely followed U.S. equity benchmarks, the Dow Jones Industrial Average^SM (the “Dow”) and the S&P 500^® Index, turning in their best monthly gains since October 2011. Investor fears about China and crude oil eased, and a weak September payroll number fueled hopes that the Fed might delay raising short-term interest rates; however, the October and November employment reports were considerably stronger. This renewed talk of a rate increase – which, in fact, finally occurred at the mid-December meeting, when the Fed hiked the target range for the federal funds rate – the Fed’s overnight bank lending rate – to 0.25%-0.50% from 0%-0.25%. Elsewhere, crude oil broke to another new low for the year in December and ended 2015 with an annual decline of 31% after falling almost 50% in 2014. These factors led to choppy market action over the final two months of the year.

The U.S. economy continued to improve, although results were mixed. For example, in mid-October, several housing reports yielded generally positive results, whereas later that month, the housing outlook was muddled by new home sales figures that were the lowest since November 2014. On the other hand, there was mostly good news on the employment front, as jobless claims experienced a favorable downward trend during the fourth quarter – and first-time jobless claims dropped to a 42-year low in mid-December. This was despite the October Job Openings and Labor Turnover Survey, which in December showed a decline in job openings from 5.526 million to 5.383 million. Employment news remained largely positive, however, as even the manufacturing sector, which struggled from falling exports due to a strong dollar, posted encouraging results in the fourth quarter of 2015.

After experiencing a steep plunge and vigorous recovery as recently as August and October, respectively, U.S. stocks repeated that scenario in the first quarter of 2016. In both cases, concerns

MassMutual RetireSMART^SM Funds – President’s Letter to Shareholders (Unaudited) (Continued)

about China’s slowing economy and falling crude oil prices helped to drive weakness in share prices. Adding to these concerns at the start of 2016 was fear of slowing global and domestic economic growth, the latter underscored by initial estimates that U.S. gross domestic product (“GDP”) expanded by a disappointing 0.7% rate in the fourth quarter of 2015, although that number was subsequently revised upward.

Share prices continued to struggle early in February, as global equity markets moved roughly in tandem with the price of oil, which declined early on, but rallied later in the month on hopes that producers would curtail supply. Concerns about the European banking system also worried investors early in February. In the U.S., a weak January employment report stoked fears that a recession could be on the horizon. However, later in the quarter, upward revisions in estimated fourth-quarter U.S. economic growth, first to 1.0% and ultimately to 1.4%, helped the equity markets rebound. The employment picture also brightened, as February’s nonfarm payrolls came in significantly stronger than the previous two months’. At the same time, the payroll numbers for both January and December were revised upward.

The rally in equities continued in March, with the Fed doing its part by reassuring investors that the central bank would be cautious about implementing further hikes in short-term interest rates. Stocks ended March near their highs for the quarter and only a scant few percent off their all-time highs.

The major stock indexes in the U.S. advanced for the six months ended March 31, 2016 – largely, but not entirely – outperforming foreign developed and emerging markets. The blue-chip Dow climbed 10.07% to lead the major market indexes for the period. Next were the large-cap stock S&P 500 Index, which rose 8.49%; and the technology-heavy NASDAQ Composite^® Index, which advanced 6.07%. The Russell 2000^® Index, a benchmark of small-cap stocks, gained a much more modest 2.02% over the six months. In international markets, the MSCI EAFE Index, an indicator of foreign developed-market stocks, posted a mere 1.56% advance, while the MSCI Emerging Markets Index, a measure of the performance of emerging stock markets throughout the world, had a more impressive 6.41% return. Fixed-income investments advanced somewhat during the period, with the Barclays U.S. Aggregate Bond Index returning 2.44%.*

MassMutual RetireSMART^SM (risk-based) Funds – Portfolio Summaries (Unaudited)

What are the investment approaches of the Funds that constitute the MassMutual RetireSMART^SM (risk-based) Series, and who is the Series’ investment adviser?

The MassMutual (“MM”) RetireSMART (risk-based) Series (the “Series”) comprises four Funds – each of which has a “fund of funds” structure. The four Funds are MM RetireSMART Conservative Fund, MM RetireSMART Moderate Fund, MM RetireSMART Moderate Growth Fund, and MM RetireSMART Growth Fund. All Funds in the Series seek to achieve as high a total return over time as is considered consistent with prudent investment risk, preservation of capital, and recognition of the Funds’ stated asset allocation.

Each Fund seeks to achieve its investment objective by investing in a combination of domestic and international mutual funds sponsored by MML Investment Advisers, LLC (MML Advisers) or its affiliates (“Underlying Funds”) using an asset allocation strategy. Underlying Funds can include MassMutual Select Funds and MassMutual Premier Funds, which are advised by MML Advisers, Babson Funds, which are advised by Babson Capital Management LLC (Babson Capital), a wholly-owned, indirect subsidiary of Massachusetts Mutual Life Insurance Company (MassMutual), and Oppenheimer Funds, which are advised by OFI Global Asset Management, Inc. (OFI Global Asset Management), a majority owned, indirect subsidiary of MassMutual. Underlying Funds may invest in various asset classes, including equity securities, fixed income securities, and money market instruments. Underlying Funds may also invest some or all of their assets directly or indirectly in one or more commodities or commodities-related investments or may themselves invest using an asset allocation strategy among equity, fixed income, money market, commodity, and other investments. The Series’ investment adviser is MML Advisers.

Each Fund’s assets are allocated among its Underlying Funds according to an asset allocation strategy, as follows:

• MM RetireSMART Conservative Fund: Assets are allocated among Underlying Funds using a conservative asset allocation strategy (relative to the other risk-based MM RetireSMART Funds), with approximately 30% of its assets invested in equity and similar funds and approximately 70% invested in fixed income funds, including money market funds.

• MM RetireSMART Moderate Fund: Assets are allocated among Underlying Funds using a moderate asset allocation strategy (relative to the other risk-based MM RetireSMART Funds), with approximately 60% of its assets invested in equity and similar funds and approximately 40% invested in fixed income funds, including money market funds.

• MM RetireSMART Moderate Growth Fund: Assets are allocated among Underlying Funds using an asset allocation strategy that emphasizes the potential for moderate growth (relative to the other risk-based MM RetireSMART Funds), with approximately 85% of its assets invested in equity and similar funds and approximately 15% invested in fixed income funds, including money market funds.

• MM RetireSMART Growth Fund: Assets are allocated among Underlying Funds using an asset allocation strategy that emphasizes the potential for growth (relative to the other risk-based MM RetireSMART Funds), with approximately 97% of its assets invested in equity and similar funds and approximately 3% invested in fixed income funds, including money market funds.

MassMutual RetireSMART^SM (target-date) Funds – Portfolio Summaries (Unaudited)

What are the investment approaches of the Funds that constitute the MassMutual RetireSMART^SM (target date) Series, and who is the Series’ investment adviser?

The MassMutual (“MM”) RetireSMART (target-date) Series (the “Series”) comprises 12 Funds – each of which has a “fund of funds” structure. The 12 Funds are MM RetireSMART In Retirement Fund, MM RetireSMART 2010 Fund, MM RetireSMART 2015 Fund, MM RetireSMART 2020 Fund, MM RetireSMART 2025 Fund, MM RetireSMART 2030 Fund, MM RetireSMART 2035 Fund, MM RetireSMART 2040 Fund, MM RetireSMART 2045 Fund, MM RetireSMART 2050 Fund, MM RetireSMART 2055 Fund, and MM RetireSMART 2060 Fund. All Funds in the Series seek to achieve as high a total return over time as is considered consistent with prudent investment risk, preservation of capital, and recognition of the Funds’ current asset allocation.

Each Fund invests in a combination of domestic and international mutual funds sponsored by MML Investment Advisers, LLC (MML Advisers) or its affiliates (“Underlying Funds”) using an asset allocation strategy designed for investors expecting to retire at age 65 around the year specified in the Fund’s name and likely to stop making new investments in the Fund at or around that time (or designed for investors already in retirement for the MM RetireSMART In Retirement Fund). Underlying Funds can include MassMutual Select Funds and MassMutual Premier Funds, which are advised by MML Advisers, Babson Funds, which are advised by Babson Capital Management LLC (Babson Capital), a wholly-owned, indirect subsidiary of Massachusetts Mutual Life Insurance Company (MassMutual), and Oppenheimer Funds, which are advised by OFI Global Asset Management, Inc. (OFI Global Asset Management), a majority owned, indirect subsidiary of MassMutual. The Underlying Funds may invest in various asset classes, including equity securities, fixed income securities, and money market instruments, as well as commodities or commodities-related investments. The Series’ investment adviser is MML Advisers.

Each Fund’s assets are allocated to its Underlying Funds according to an asset allocation strategy, as follows:

• MM RetireSMART In Retirement Fund: Assets are allocated among Underlying Funds according to a target asset allocation strategy that emphasizes fixed income and money market funds, but also includes a smaller allocation to equity and certain other funds.

• MM RetireSMART 2010/2015/2020/2025/2030/2035/2040/2045/2050/2055/2060 Funds: For each Fund, assets are allocated among Underlying Funds according to an asset allocation strategy that becomes increasingly conservative until it reaches approximately 35% in equity and similar funds and 65% in fixed income funds, including money market funds, approximately 15 years after the target retirement date.

The principal difference among the classes is the level of service and administration fees, and shareholder and distribution service expenses borne by the classes. Because each class will have different fees and expenses, performance and share prices will vary between the classes. The classes of shares are offered to different types of investors, as outlined in the Funds’ Prospectus.

On May 13, 2015, the Board of Trustees (“Trustees”) approved a change in the fiscal year end of the Funds from December 31 to September 30. Accordingly, the Funds’ financial statements and related notes include information as of the nine month period ended September 30, 2015, and the year ended December 31, 2014.

Effective March 14, 2014, Class L shares of the MM RetireSMART In Retirement Fund, MM RetireSMART 2010 Fund, MM RetireSMART 2015 Fund, MM RetireSMART 2020 Fund, MM RetireSMART 2025 Fund, MM RetireSMART 2030 Fund, MM RetireSMART 2035 Fund, MM RetireSMART 2040 Fund, MM Retire SMART 2045 Fund, MM RetireSMART 2050 Fund, and MM RetireSMART 2055 Fund merged into Class Y shares (now known as Administrative Class shares).

Effective April 1, 2014, Class S shares were renamed Class R5 shares, Class Y shares were renamed Service Class shares, and Class L shares were renamed Administrative Class shares for the MM RetireSMART Conservative Fund, MM RetireSMART Moderate Fund, MM RetireSMART Moderate Growth Fund, and MM RetireSMART Growth Fund. Effective April 1, 2014, Class S shares were renamed Service Class shares, and Class Y shares were renamed Administrative Class shares for the MM RetireSMART In Retirement Fund, MM RetireSMART 2010 Fund, MM RetireSMART 2015 Fund, MM RetireSMART 2020 Fund, MM RetireSMART 2025 Fund, MM RetireSMART 2030 Fund, MM RetireSMART 2035 Fund, MM RetireSMART 2040 Fund, MM RetireSMART 2045 Fund, MM RetireSMART 2050 Fund, and MM RetireSMART 2055 Fund.

Mutual Life Insurance Company (“MassMutual”)) and Oppenheimer Funds (which are advised by OFI Global Asset Management, Inc., a majority-owned, indirect subsidiary of MassMutual) are presented separately and can be obtained from the Securities and Exchange Commission’s (“SEC”) EDGAR database on its website at http://www.sec.gov or by calling MML Advisers at 1-888-309-3539. The assets of each Fund are diversified and a shareholder’s interest is limited to the Select, Premier, Babson, or Oppenheimer Funds in which the shares are invested.

2. Significant Accounting Policies

The following is a summary of significant accounting policies followed consistently by each Fund in the preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“generally accepted accounting principles”). The preparation of the financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

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.

The net asset value of each Fund is based upon the net asset value(s) of its corresponding underlying funds. Shares of the underlying funds are valued at their closing net asset values as reported on each business day.

Certain underlying 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 value 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 Prospectuses and Statements of Additional Information (“SAIs”) for the underlying funds explain the valuation methods for the underlying funds, including the circumstances under which the underlying funds may use fair value pricing and the effects of doing so. Such Prospectuses and SAIs are available on the SEC’s EDGAR database on its website at http://www.sec.gov.

Various inputs may be used to determine the value of the Funds’ investments. The Funds categorize the inputs to valuation techniques used to value their investments into a disclosure hierarchy consisting of three levels as summarized below. The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.

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 (including the Funds’ own assumptions in determining the fair value of investments)

Each Fund characterized all investments at Level 1, as of March 31, 2016. For each Fund, the level classification by major category of investments is the same as the category presentation in the Portfolio of Investments.

The due to custodian amounts shown in the Statements of Assets and Liabilities approximate fair value, which would be categorized at Level 2, as of March 31, 2016.

The Funds had no transfers between Level 1, Level 2 and Level 3 of the fair value hierarchy during the period ended March 31, 2016. The Funds recognize transfers between the Levels as of the beginning of the year.

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 and distributions including realized gain distributions are 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 gain are recorded as a reduction of cost of investments and/or as a realized gain. The Funds determine the classification of distributions received as return of capital distributions or capital gain distributions.

Allocation of Operating Activity

In maintaining the records for the Funds, the income and expense accounts are allocated daily to each class of shares. Investment income and loss, and unrealized and realized gains or losses are prorated among the classes of shares based on the relative net assets of each. Expenses are allocated to each class of shares depending on the nature of the expenditures. Administration and service fees, if any, which are directly attributable to a class of shares, are charged to that class’s operations. Expenses of a Fund not directly attributable to the operations of any specific class of shares of the Fund are prorated among the classes to which the expense relates based on relative net assets.

In addition, each Fund will also incur certain fees and expenses indirectly as a shareholder in the underlying funds. Because the underlying funds have varied expense and fee levels and each Fund may own different proportions of underlying funds at different times, the amount of fees and expenses indirectly incurred by each Fund will vary.

Foreign Securities

Certain underlying funds 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, and diplomatic risks. In addition, fluctuations in currency exchange rates may adversely 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, greater price volatility, higher relative rates of inflation, greater political, economic, and social instability, greater custody and operational risks, and greater volatility in currency exchange rates.

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 (the “Code”), 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.

Pursuant to a 12b-1 Plan adopted by the Trust, Class A shares and Class R4 shares of each Fund pay an annual fee of 0.25% of the average daily net assets of the class; and Class R3 shares of each Fund pay an annual fee of 0.50% of the average daily net assets of the class, to the Distributor. Such payments compensate the Distributor for services provided and expenses incurred by it for purposes of promoting the sale of the relevant class of shares, reducing redemptions of shares, or maintaining or improving services provided to each Fund’s shareholders. The Distributor is a wholly-owned subsidiary of MassMutual.

The Trust has entered into a separate Supplemental Shareholder Services Agreement with MassMutual, on behalf of Service Class shares, Administrative Class shares, and Class A shares of each Fund. Fees payable under the Supplemental Shareholder Services Agreement are intended to compensate MassMutual for its provision of shareholder services to the Funds’ investors and are calculated and paid based on the average daily net assets attributable to the relevant share classes of the Funds separately, at the following annual rates: 0.05% for Service Class shares, and 0.15% for Administrative Class shares and Class A shares. MassMutual may pay these fees to other intermediaries for providing shareholder services to the Funds’ investors.

Net capital loss carryforwards may be applied against any net realized taxable gains in succeeding years, subject to the carryforward period limitations, where applicable. On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the “Modernization Act”) was signed by the President. The Modernization Act changed the capital loss carryforward rules as they relate to regulated investment companies. Capital losses generated in tax years beginning after the date of enactment may now be carried forward indefinitely, and retain the character of the original loss. Under pre-enactment law, capital losses could be carried forward for up to eight tax years as short-term capital losses. The provisions affecting the utilization of capital loss carryforwards under the Modernization Act also require the utilization of post-enactment losses prior to the utilization of pre-enactment losses.

At September 30, 2015, the following Fund(s) had available, for federal income tax purposes, unused capital losses:

	Expiring 2016		Expiring 2017		Expiring 2018
MM RetireSMART In Retirement Fund	$	-	$	15,312,688	$	-
MM RetireSMART 2010 Fund		-		15,571,571		865,289

Net capital loss carryforwards for the Fund(s) shown in the above table are from pre-enactment years and are, therefore, subject to the eight-year carryforward period and possible expiration.

Generally accepted accounting principles in the United States of America require that only distributions in excess of tax basis earnings and profits be reported in the financial statements as a return of capital.

The Funds may elect to pass-through to shareholders the income tax credit for taxes paid to foreign countries. If elected, the passthrough of the foreign tax credit will affect only those persons who are shareholders on the dividend record date in December 2015. These shareholders will receive more detailed information along with their 2015 Form 1099-DIV.

Capital accounts within the financial statements are periodically adjusted for permanent differences between book and tax accounting. These adjustments have no impact on net assets or the results of operations. Temporary book and tax accounting differences will reverse in subsequent periods. At September 30, 2015, temporary book and tax accounting differences were primarily attributable to the deferral of wash sale losses, non-taxable dividend basis adjustments, and deferred Trustee compensation.

At September 30, 2015, the components of distributable earnings on a tax basis were as follows:

Notes to Financial Statements (Unaudited) (Continued)

8. Indemnifications

Under the Funds’ organizational documents, current and former Trustees and Officers are provided with specified rights to indemnification against liabilities arising in connection with the performance of their duties to the Funds, and shareholders are indemnified against personal liability for obligations of the Funds. In the normal course of business, the Funds may also enter into contracts that provide general indemnifications. The Funds’ maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Funds. The risk of material loss from such claims is considered remote.

9. New Accounting Pronouncements

In May 2015, The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2015-07, Fair Value Measurement (Topic 820): “Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)” (“ASU 2015-07”) to address the diversity in practice of how investments measured at net asset value with redemption dates in the future (including periodic redemption dates) are categorized within the fair value hierarchy. ASU 2015-07 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2015. Management is currently evaluating the implications of these changes and their impact to the financial statements.

10. Subsequent Events

In preparation of these financial statements, management has evaluated the events and transactions subsequent to March 31, 2016, through the date when the financial statements were issued, and determined that there are no subsequent events or transactions that would require adjustments to or disclosures in the Funds’ financial statements.

Trustees’ Approval of Investment Advisory Contracts

At their meeting in November 2015, the Trustees, including the Trustees who are not “interested persons” (as such term is defined in the 1940 Act) of the Trust or MML Advisers (the “Independent Trustees”), reviewed and approved the advisory agreement for one new series of the Trust, the MM RetireSMART 2060 Fund (the “New Fund”), subject to approval by the shareholders of the New Fund of the advisory agreement. In preparation for the meeting, the Trustees requested, and MML Advisers provided in advance, certain materials relevant to the consideration of the advisory agreement (the “Materials”). In all of their deliberations, the Trustees were advised by independent counsel.

In reviewing and approving the advisory agreement, the Trustees considered the Materials and information discussed with representatives of MML Advisers at the meeting relating to MML Advisers and the nature, scope, and quality of services MML Advisers would provide to the New Fund. The Trustees considered a number of factors they believed to be relevant to the interests of shareholders of the New Fund including: (i) the financial condition, stability, and business strategy of MML Advisers; (ii) the capabilities of MML Advisers with respect to regulatory compliance and its ability to monitor compliance with the investment policies of the New Fund; (iii) MML Advisers’ ability to provide investment oversight and administrative and shareholder services to the New Fund; (iv) the experience and qualifications of the personnel of MML Advisers that perform, or oversee the performance of, the services provided to the New Fund and the needs of the New Fund for administrative and shareholder services; and (v) the proposed advisory fee for the New Fund and comparative information regarding fees paid by peer funds.

The Trustees also reviewed and considered information included in the Materials, or discussed at the meeting, concerning possible economies of scale and potential profitability of MML Advisers’ advisory relationship with the New Fund. The discussions included consideration of the intangible benefits derived by MML Advisers and its affiliates resulting from their relationships with the New Fund and the so-called “fallout benefits” to MML Advisers, such as any reputational value derived from serving as investment adviser to the New Fund.

Prior to the votes being taken to approve the advisory agreement, the Independent Trustees met separately in executive session to discuss the appropriateness of the contract. The Independent Trustees weighed the foregoing matters in light of the advice given to them by their independent legal counsel as to the law applicable to the review of investment advisory contracts. In arriving at a decision, the Trustees, including the Independent Trustees, did not identify any single matter as all-important or controlling. The foregoing summary does not detail all of the matters considered.

Based on the foregoing, the Trustees concluded that: (i) overall, they were satisfied with the nature, extent, and quality of services expected to be provided under the advisory agreement, including the anticipated level of MML Advisers’ oversight of the New Fund; (ii) MML Advisers’ projected level of profitability from its relationship with the New Fund was not excessive and the advisory fee amount under the advisory agreement and the New Fund’s total expenses are fair and reasonable; (iii) the investment processes, research capabilities, and philosophies of MML Advisers would be well suited to the New Fund given its investment objective and policies; and (iv) the terms of the advisory agreement were fair and reasonable with respect to the New Fund and were in the best interests of the New Fund’s shareholders.

The advisory agreement became effective on November 23, 2015

Fund Expenses March 31, 2016

Expense Examples:

The following information is in regards to expenses for the six months ended March 31, 2016:

As a shareholder of the Funds, you may incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemptions; and (2) ongoing costs, including advisory fees, distribution and/or service (12b-1) fees, and other Fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds. These examples are based on an investment of $1,000 invested for the six months ended March 31, 2016.

Actual Expenses:

The first four columns of the table below provide information about actual account values and actual expenses. You may use this information, 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 under the heading entitled “Operating Expenses Incurred” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes:

The last two columns of the table below provide information about hypothetical account values and hypothetical expenses based on the 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 the 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.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs. Therefore, the last two columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.
