MML Series Investment Fund

MML Moderate Allocation Fund


Before you invest, you may want to review the Fund’s prospectus, which contains more information about the Fund and its risks. You can find the Fund’s prospectus and other information about the Fund online at www.massmutual.com/funds. You can also get this information at no cost by calling 1-888-309-3539 or by sending an email request to fundinfo@massmutual.com.



The Fund seeks to achieve as high a total rate of return on an annual basis as is considered consistent with prudent investment risk and the preservation of capital.



This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The expenses in the table do not reflect deductions at the separate account level or contract level for any charges that may be incurred under a variable life insurance or variable annuity contract.


Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)



Management Fees

  .10%   .10%

Distribution and Service (Rule 12b-1) Fees

  N/A   .25%

Other Expenses

  .02%   .02%

Acquired Fund Fees and Expenses

  .71%   .71%

Total Annual Fund Operating Expenses(1)

  .83%   1.08%
(1)   Because Total Annual Fund Operating Expenses include Acquired Fund fees and expenses, they may not correspond to the ratios of expenses to average daily net assets shown in the “Financial Highlights” tables in the Prospectus, which reflect the operating expenses of the Fund and do not include Acquired Fund fees and expenses.



This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It assumes that you invest $10,000 in each share class of the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment earns a 5% return each year and that the Fund’s operating expenses are exactly as described in the preceding table. If separate account or variable life insurance or variable annuity contract expenses were included, overall

expenses would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


     1 Year      3 Years      5 Years      10 Years  

Initial Class

   $ 85       $ 265       $ 460       $ 1,025   

Service Class

   $ 110       $ 343       $ 595       $ 1,317   


Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio.




Principal Investment Strategies

The Fund is a “fund of funds” and seeks to achieve its investment objective by investing in a combination of domestic and international mutual funds (“Underlying Funds”) using an asset allocation strategy. Underlying Funds can include series of the MML Series Investment Fund, MML Series Investment Fund II (which are advised by MassMutual), OppenheimerFunds (which are advised by OppenheimerFunds, Inc. (“OFI”), a majority owned, indirect subsidiary of MassMutual), and non-affiliated funds. The Underlying Funds may invest in various asset classes, including equity securities, fixed income securities, and money market instruments. The Fund has a moderate asset allocation strategy (relative to the other MML Allocation Funds), with approximately 60% of its assets invested in equity funds and approximately 40% invested in fixed income funds, including money market funds. In its periodic determination of the Fund’s asset allocation to Underlying Funds,




MassMutual will attempt to select Underlying Funds that it expects will provide an aggregate exposure to “junk” or “high yield” bonds (securities rated below investment grade by Moody’s or Standard & Poor’s, or unrated securities determined to be of comparable quality by the applicable adviser or subadviser), including securities in default, of not more than 10% of the Fund’s assets (although the Fund’s exposure may from time to time exceed that percentage).


The table below shows the Fund’s approximate allocation, as of March 30, 2012, among various asset classes and Underlying Funds. The Fund’s investment adviser, MassMutual, intends to manage the Fund according to the Fund’s asset allocation strategy, and does not intend to trade actively among Underlying Funds or to attempt to capture short-term market opportunities as primary activities. MassMutual may modify the asset allocation strategy or the selection of Underlying Funds from time to time, and may invest in other Underlying Funds, including any Underlying Funds that may be created in the future. At any given time, the Fund’s asset allocation may be affected by a variety of factors (such as, for example, whether an Underlying Fund is accepting additional investments).

Through its investments in Underlying Funds, the Fund may be exposed to a wide range of securities and other instruments with differing characteristics (such as credit quality, duration, geography, industry, and market capitalization), including, but not limited to, equity securities of small-, mid-, or large-capitalization U.S. or non-U.S. issuers, fixed income securities of U.S. or non-U.S. private or governmental issuers (including “junk” or “high yield” bonds, including securities in default), inflation-protected securities, bank loans, and short-term investments of any kind. Equity securities may include common stocks, preferred stocks, securities convertible into common or preferred stock, rights, and warrants. An Underlying Fund may engage in foreign currency exchange transactions, including forward contracts, options on currency, futures contracts, and swap contracts, to take long or short positions in foreign currencies in order to enhance its investment return, or to attempt to protect against adverse changes in currency exchange rates. An Underlying Fund may be permitted to use a wide




variety of additional exchange-traded and over-the-counter derivatives, including options, futures contracts, swap contracts (including interest rate swaps, total return swaps, and credit default swaps), and hybrid instruments. An Underlying Fund may typically use these derivatives for hedging purposes, as a substitute for direct investments, to earn additional income, to gain exposure to securities or markets in which it might not be able to invest directly, or to adjust various portfolio characteristics, including the duration (interest rate volatility) of the Fund’s portfolio of debt securities. Use of derivatives by an Underlying Fund may create investment leverage. An Underlying Fund may enter into repurchase agreement transactions. An Underlying Fund may invest in mortgage-backed or other asset-backed securities. An Underlying Fund may enter into dollar roll or reverse repurchase agreement transactions. The Fund will bear a pro rata share of the Underlying Funds’ expenses. The Fund also bears all of the risks associated with the investment strategies used by the Underlying Funds.


Principal Risks

The following are the Principal Risks of the Fund. You have the potential to make money by investing in the Fund, but you can also lose money. Except as otherwise stated, references in this section to “the Fund” or “a Fund” may relate to the Fund, one or more Underlying Funds, or both.


Bank Loans Risk Bank loans in which the Fund may invest have similar risks to lower-rated fixed income securities. 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. Senior secured bank loans are supported by collateral; however the value of the collateral may be insufficient to cover the amount owed to the Fund. If the Fund relies on a third party to administer a loan, the Fund is subject to the risk that the third party will fail to perform its obligations. In addition, if the Fund holds only a participation interest in a loan made by a third party, the Fund’s receipt of payments on the loan will be dependent on the third party’s willingness and ability to make those payments to the Fund.


Cash Position Risk The ability of the Fund to meet its objective may be limited to the extent that it holds assets in cash or otherwise uninvested.


Convertible Securities Risk Convertible securities are subject to the risks of both debt securities and

equity securities. The values of convertible securities tend to decline as interest rates rise and, due to the conversion feature, tend to vary with fluctuations in the market value of the underlying common or preferred stock.


Credit Risk The Fund is subject to the risk that the issuer of an investment held by the Fund or the counterparty to a transaction entered into by the Fund will be unable or unwilling to honor its obligations.


Derivatives Risk Derivatives involve risks different from, and potentially greater than, direct investments, including risks of imperfect correlation between the value of derivatives and underlying assets, counterparty default, potential losses that partially or completely offset gains, and illiquidity. Derivatives can create investment leverage and be highly volatile. Derivatives may result in losses greater than the amount invested. Many derivatives are traded in the over-the-counter market and not on exchanges.


Dollar Roll and Reverse Repurchase Agreement Transaction Risk These transactions generally create leverage and subject the Fund to the credit risk of the counterparty.


Fixed Income Securities Risk The values of fixed income securities typically will decline during periods of rising interest rates, and can also decline in response to changes in market, economic, industry, political, and regulatory conditions affecting a particular type of security or issuer or fixed income securities generally. Fixed income securities are subject to interest rate risk (the risk that the value of a fixed income security will fall when interest rates rise), extension risk (the risk that the average life of a security will be extended through a slowing of principal payments), prepayment risk (the risk that a security will be prepaid and the Fund will be required to reinvest at a less favorable rate), and credit risk.


Foreign Investment Risk; Emerging Markets Risk; Currency Risk Foreign securities, including ADRs, 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 and economic




instability, and greater volatility in currency exchange rates.


Growth Company Risk The prices of growth securities are often more sensitive to market fluctuations because of their heavy dependence on future earnings expectations, and can be more volatile than the market in general.


Inflation Risk The value of assets or income from the Fund’s investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund’s assets can decline as can the value of the Fund’s distributions.


Liquidity Risk Certain securities may be difficult (or impossible) to sell or positions difficult to close out at a desirable time and price, and the Fund may be required to hold an investment that is declining in value or be prevented from realizing capital gains.


Lower-Rated Fixed Income Securities Risk Lower-rated securities, commonly known as “junk” or “high yield” bonds, have speculative characteristics and involve greater volatility of price and yield, greater risk of loss of principal and interest, and generally reflect a greater possibility of an adverse change in financial condition that could affect an issuer’s ability to honor its obligations.


Management Risk The Fund relies on the manager’s ability to achieve its investment objective. There can be no assurance that the Fund will achieve the desired results and the Fund may incur significant losses.


Market Risk The value of the Fund’s portfolio securities may decline, at times sharply and unpredictably, as a result of unfavorable market-induced changes affecting particular industries, sectors, or issuers. Stock market prices in general may decline over short or extended periods, subjecting the Fund to unpredictable declines in the value of its shares and poor performance. The Fund is subject to risks affecting issuers, such as management performance, financial leverage, industry problems, and reduced demand for goods or services.


Mortgage- and Asset-Backed Securities Risk Investments in mortgage- and asset-backed securities subject the Fund to interest rate risk, extension risk, and prepayment risk, among other risks. The types of mortgages (for example, residential or commercial mortgages) underlying securities held by the Fund may differ and be affected differently by market

factors. Investments that receive only the interest portion or the principal portion of payments on the underlying assets may be more volatile than other investments. The market for mortgage- and asset-backed securities has recently experienced high volatility and a lack of liquidity. As a result, the value of many of these securities has significantly declined.


Preferred Stock Risk Preferred stocks are subject to the risks associated with other types of equity securities, as well as additional risks, such as potentially greater volatility and risks related to deferral, non-cumulative dividends, subordination, liquidity, limited voting rights, and special redemption rights.


Repurchase Agreement Risk These transactions 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.


Risk of Investment in Other Funds or Pools The Fund is indirectly exposed to all of the risks of the underlying funds, including exchange-traded funds, in which it invests, including the risk that the underlying funds will not perform as expected. The Fund indirectly pays a portion of the expenses incurred by the underlying funds.


Smaller and Mid-Cap Company Risk Market risk and liquidity risk are particularly pronounced for securities of smaller companies, which may trade less frequently and in smaller volumes than more widely- held securities, and may fluctuate in price more than other securities. Smaller companies may have limited product lines, markets, or financial resources and may be dependent on a limited management group; they may have been recently organized and have little or no track record of success.


U.S. Government Securities Risk Obligations of certain U.S. government agencies and instrumentalities are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to such agencies and instrumentalities.


Valuation Risk The Fund is subject to the risk of mispricing or improper valuation of its investments, in particular to the extent that its securities are fair valued.




Value Company Risk The value investment approach entails the risk that the market will not recognize a security’s intrinsic value for a long time, or that a stock judged to be undervalued may actually be appropriately priced.


When-Issued, Delayed Delivery, TBA, and Forward Commitment Transaction Risk These transactions may create leverage and involve a risk of loss if the value of the securities declines prior to settlement.


Performance Information

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund’s performance from year to year for Initial Class shares. The table shows how the Fund’s average annual returns for 1 year, and since inception, compare with those of a broad measure of market performance (Russell 3000® Index) and additional indexes, including an index that provides a comparison relevant to the Fund’s allocation to fixed income investments, an index that provides a comparison relevant to the Fund’s allocation to international investments, and a hypothetical custom index which comprises the Barclays Capital U.S. Aggregate Bond, Russell 3000, and MSCI® ACWI® ex-U.S. Indexes. Performance shown does not reflect the fees and expenses deducted under the variable life insurance or variable annuity contract through which you invest in the Fund. If these amounts were reflected, returns would be less than those shown. Past performance is not necessarily an indication of how the Fund will perform in the future.

Investment Adviser: Massachusetts Mutual Life Insurance Company


Portfolio Manager: Stephen J. Brunette, CFA is an Assistant Vice President for the Investment Advisory Group of Annuity Products for MassMutual’s U.S. Insurance Group. He has managed the Fund since its inception.



Shares of the Fund are generally available to separate investment accounts of variable life insurance and




variable annuity contracts offered by companies such as MassMutual. The methods that can be used to redeem Fund shares are subject to the variable contract issuing company.



Dividends and capital gain distributions are paid to the insurance company separate accounts. Variable life insurance and variable annuity contract owners should refer to the variable life insurance or variable annuity product prospectus or consult with their own tax adviser for information regarding the tax consequences of their investment.



The Fund is not sold directly to the general public but instead is offered as an underlying investment option

for variable insurance contracts. The Fund and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may be a factor that the insurance company considers in including the Fund as an underlying investment option in the variable insurance contract or may create a conflict of interest by influencing the insurance company or other intermediary to recommend the variable insurance contract over another investment. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.
