MML Series Investment Fund II – President's Letter to Shareholders

To Our Shareholders

Richard J. Byrne

The improvement in the investing environment over the past 10 months has shown us that changing market conditions have the potential to reward patient investors. In MassMutual's view, it's your long-term investment objectives that matter most. So be sure to look to your long-term goals whenever you consider making any changes to your account or your retirement planning strategy.

Continued market improvements buoy retirement investors' spirits

I am pleased to present you with the MML Series Investment Fund II Annual Report, covering the year ended December 31, 2009. While deteriorating market conditions continued to challenge investors into the first quarter of 2009 after a difficult 2008, most of 2009 showed a resurgence of equity markets throughout the world and proved once again that market conditions are truly cyclical. The economic climate began to recover during this time frame, resulting in a similar uptick in investor sentiment – although significant progress on a number of fronts still needs to occur.

In MassMutual's view, this improving market environment underscores the importance for you to focus on a long-term investment strategy designed to suit your investment time horizon and your tolerance for risk. Now may be an excellent time to consult with your financial professional to assess your overall retirement plan. Together, you can determine if any adjustments should be made to your overall portfolio or your contribution levels to help you reach your long-term financial goals.

Time-tested suggestions for retirement investors

Regardless of current market conditions, when devising your retirement planning strategy, it may help you to keep the following in mind:

Retirement investing is a long-term proposition. If you're like most retirement investors, you won't be looking to liquidate your retirement funds in 2010. Even if you do begin to withdraw money this year, the majority of your assets will likely remain invested for many years to come. It's important to keep in mind that you're in it for the long term, even if retirement is approaching. Whenever short-term changes in the markets give you pause, try to remember that markets can and do suffer downturns, but have tended to regain value over time.
Continue to invest. Making investments at regular intervals, regardless of market conditions, can help you to take advantage of market swings by buying more shares/units when prices are down, and fewer shares/units when prices are up.*
Monitor your asset allocation and diversify. Stocks, bonds, and short-term/money market investments are asset classes that often behave differently, depending upon the economic and market environment. These broad asset classes include an even greater array of asset sub-categories (such as small-cap stocks, international stocks, and high-yield bonds). When determining the asset allocation for your retirement portfolio, remember that financial professionals often advise their clients to select a wide range of investments from different asset classes. We believe it is important to keep your tolerance for risk in mind when making your selections. Be sure to monitor your asset allocation regularly to ensure that it remains in line with your long-term financial goals and investment time horizon.*

* Systematic investing and asset allocation do not ensure a profit or protect against loss in a declining market. Systematic investing involves continuous investment in securities regardless of fluctuating price levels. Investors should consider their ability to continue investing through periods of low price levels.

You're in it for the long term

While short-term changes in the markets or day-to-day events can be unsettling, MassMutual continually focuses on the long term and encourages investors to do the same. That's one reason why we believe doing business with MassMutual is the sign of a good decision.

Thank you for your continued confidence in MassMutual.

Sincerely,

Richard J. Byrne

MML Series Investment Fund II – Economic and Market Review

December 31, 2009

Worldwide financial market conditions begin to improve after a rough start to the year

The year ended December 31, 2009 marked a time of transition for investment markets worldwide. As 2009 began, U.S. markets had already been battered for months by extreme economic conditions, including weakness in the housing market, scarcely available credit, the well-publicized meltdowns of some of Wall Street's most venerable companies, the struggles of U.S. automakers, high unemployment rates, and an extremely soft retail environment. Encouraging news in the economy and financial markets was hard to come by, and the environment mainly continued on its downward spiral until March 2009, when stocks worldwide kicked off a rally that ultimately drove most broad stock and bond indexes to one-year gains by the end of December.

Throughout the world, many economies began the slow recovery process — although some continued to struggle. For example, in Europe, the United Kingdom did especially well. Similarly, France and Germany unexpectedly pulled out of recession. Conversely, high-deficit euro countries, including Ireland and Greece, continued to suffer. Elsewhere, China's and Brazil's economies proved resilient and the Russian economy, which had slowed late in 2008, began to recover during the third quarter of 2009. Economic conditions in Turkey and Indonesia also began to turn around in April 2009, when emerging equity markets began to perform well.

In the U.S., although numerous economic challenges — such as high unemployment levels and struggling consumer confidence levels — continued to be a concern, a resurgence in equity markets seemed to point, for many, to an economy that was potentially on the road to recovery.

Market performance

Both bonds and equities were positive for the 12 months ended December 31, 2009, with notable outperformers in each of the two asset classes. The Dow Jones Industrial Average^SM (the "Dow"), a measure of blue-chip stock performance, advanced 18.82%. The S&P 500^® Index (the "S&P 500"), a measure of U.S. large-cap stock performance, also gained traction for the year and returned 26.46%. Another winner in the equities category was the technology-heavy NASDAQ Composite^® Index ("NASDAQ"), with its impressive 43.89% return. Worldwide equity markets significantly outperformed their U.S. counterparts. For example, the Morgan Stanley Capital International ("MSCI^®") Europe, Australasia, Far East ("EAFE^®") Index, a benchmark for foreign stocks in developed markets, advanced 31.78%. The clear winner, however, was the MSCI Emerging Markets Index, a benchmark that represents the performance of emerging stock markets throughout the world, which advanced a stunning 78.51% for the year ended December 31, 2009.

Investments in the fixed-income markets tended to trail their equity counterparts in 2009. One of the most closely monitored benchmarks in the fixed-income market, the Barclays Capital U.S. Aggregate Bond Index, a broad measure of the U.S. investment-grade bond markets, gained 5.93%. Treasury bills advanced slightly, gaining just 0.20% for the year, as measured by the Citigroup 3-Month Treasury Bill Index. But the star performer in the fixed-income arena was the Barclays Capital U.S. Corporate High-Yield Bond Index, a measure of the performance of fixed rate, non-investment-grade debt from corporate sectors, which returned 58.21% for the year. Trailing the group was the small-by-comparison 1.41% advance of the Barclays Capital U.S. 1-3 Year Government Bond Index, which measures the performance of U.S. government bonds with one to three years remaining to the scheduled payment of principal.*

First quarter of 2009: the tide begins to turn

As 2009 began, investors digested and reacted to economic events and news, but found few reasons for much optimism in January and February. President Obama's $787 billion economic stimulus package received approval from Congress in February and offered a variety of incentives, including tax cuts, infrastructure spending, and assistance for states. This had little effect on investor sentiment, however, as dismal news concerning unemployment, housing, available credit, and ongoing struggles of companies of all sizes in

MML Series Investment Fund II – Economic and Market Review (Continued)

a variety of sectors (particularly financial services and automobile makers) dominated the headlines. By early March, both the Dow and the S&P 500 had declined to lows not seen in well over a decade.

Almost unexpectedly, stocks staged a vigorous late-quarter rally that enabled major market benchmarks to trim their losses for the quarter and post solid gains for March. Investors finally seemed encouraged by actions taken by the U.S. government and governments worldwide, along with a handful of economic reports that signaled positive movement. Other news also surfaced to help the rally along, particularly the Federal Reserve's (the "Fed") announcement of the plan to buy $300 billion in long-term Treasury securities. Although the advances in late March were not enough to counteract the market declines of the first two months of the year — most stocks posted double-digit losses for the quarter and bonds posted mixed results overall — they did mark a significant turning point in the economic climate and helped to bring renewed optimism to investors who had been discouraged by the relentless market losses of the previous 12 to 15 months.

Encouraging signs continue in the second quarter of 2009

The stock market advanced substantially during the second quarter of 2009, although the rally lost some momentum in June. Share prices rose for much of the period on encouraging economic reports. During the quarter, headlines focused on the bankruptcies of automakers Chrysler and General Motors, but investors seemed to believe that the worst of the financial crisis had passed and generally overlooked bad news to focus on the "green shoots" of a potential economic recovery. The consistency of the advance was remarkable, as periods of decline in this environment were shallow and short-lived. Foreign stocks also turned in strong results during the second quarter, aided by gains in local share prices and a falling U.S. dollar. In the bond market, Treasury securities struggled, while riskier bonds outperformed. Rising yields sent Treasury prices lower (when yields rise, the prices of existing bonds fall — and vice versa) amid heightened concerns about the possibility of inflation becoming a greater threat due to increases in the money supply and borrowing required by the U.S. government's attempts to jump-start the economy. Despite the surge in Treasury yields, corporate bond spreads (the difference in yields between comparable bonds) narrowed considerably, reflecting increased demand and rising prices.

Some data releases during the second quarter of 2009 proved encouraging. One of those was durable goods orders, which surged by 1.8% in May, surprising economists who had expected a decline. May's increase was the third in four months and followed a similarly robust advance in April. Furthermore, one of the more closely watched releases, the Conference Board's Index of Leading Economic Indicators (LEI), rose by 1.2% in May, following a revised 1.1% increase in April. The two months of increases represented the best back-to-back performance of this measure since late 2001. As its name implies, this index is valued for its forward-looking ability — whereas many measures of economic activity (such as employment-related data) are lagging indicators, meaning they tend to follow, rather than forecast, economic trends.

Markets maintain momentum in the third quarter of 2009

U.S. stocks piled on more gains during the third quarter of 2009, as the market rally stretched into its seventh month (since March lows). After beginning the quarter on an uncertain note, equities benefited from a fresh burst of bullish enthusiasm around the middle of July, amid favorable prospects for second-quarter earnings. The pace of the advance slowed in August and September, but stock prices managed to work higher during both months, as investors drove double-digit gains in the most widely followed stock benchmarks for the second straight quarter. On a similar note, foreign stocks in developed markets kept pace with their domestic counterparts, receiving a boost from U.S. dollar weakness.

Risk-wary investors in the U.S. and abroad drove up prices for U.S. Treasury securities. Additionally, corporate bonds benefited from easing concerns about company balance sheets and earnings growth, which enabled the Barclays Capital U.S. Aggregate Bond Index to post a modest return for the quarter. Conversely, investors' pursuit of returns lifted the Barclays Capital U.S. Corporate High-Yield Bond Index to a double-digit gain of 14.22% for the three-month period. Short-term government bonds turned in some of the quarter's most modest results, but still managed to gain a bit of ground.

MML Series Investment Fund II – Economic and Market Review (Continued)

Fourth quarter of 2009 sees continued stock market gains; international concerns

U.S. stocks climbed higher in the final quarter of 2009, amid a growing consensus that the economy had begun to recover. (Held in check partly by a U.S. dollar rally in December, foreign stocks in developed markets lagged their domestic counterparts.) Reinforcing this belief was solid growth in third-quarter GDP (gross domestic product), which reflects the total value of goods and services produced in the United States. That said, the GDP estimate was revised to a lower level twice as the quarter progressed, from 3.5% to 2.8%, and finally to 2.2%. These revisions and some disappointing news on the housing market that surfaced later in the quarter may have helped slow the market's momentum from mid-November through the end of 2009. Elsewhere, bond market returns were generally subdued. The growing conviction that the U.S. economy was in the early stages of a recovery, fears of an eventual rebound in inflation, and an ample supply of securities — courtesy of auctions held by the U.S. Treasury to finance the federal government's deficit — converged to push Treasury bond yields higher and prices lower.

One note of great concern for financial markets worldwide occurred near the end of November, when Dubai World, a government-owned conglomerate and Dubai's largest corporate entity, threatened to delay, by six months, debt repayments in the amount of $26 billion. Ultimately, by the close of the month, Dubai World announced the restructuring of that debt — generally easing a great deal of international tension, although concerns remained as the year came to a close (and the restructuring process was still underway).

As 2009 came to a close, it remained to be seen whether or not the economic growth that was evident in the latter part of the year would pave the way for similar growth in 2010. Concerns lingered over both the future spending ability of the U.S. consumer — who still appeared to be primarily concerned with paying down debt and stockpiling cash — and the state of the housing market, which had begun to show signs of bottoming at the end of 2009. On the other hand, consumer confidence, as measured by the Conference Board Consumer Confidence Index, saw an uptick in both November and December 2009, leading some to enter 2010 with restrained optimism regarding the near-term prospects for the U.S. economy.

MML Money Market Fund – Portfolio Manager Report

What is the investment objective of MML Money Market Fund, and who is the Fund's subadviser?

The Fund seeks to achieve high current income, the preservation of capital, and liquidity. These objectives are of equal importance. The Fund invests in high-quality debt instruments that have a remaining maturity not exceeding 397 days. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund. The Fund's subadviser is Babson Capital Management LLC (Babson Capital).

How did the Fund perform during the 12 months ended December 31, 2009?

The Fund's Initial Class shares returned 0.07%, underperforming the 0.25% return of the Lipper Taxable Money Market Fund Index (the "benchmark"), an unmanaged index of taxable money market mutual funds.

For a discussion on the economic and market environment during the 12-month period ended December 31, 2009, please see the Economic and Market Review, beginning on page 3.

Subadviser discussion of factors that contributed to the Fund's performance

Overall, the Fund performed well during a year marked by historically low yields, scarcity of money market investments, and ample liquidity. The drastically low supply was due to issuers either cutting back their borrowing or moving a larger percentage of their debt into longer-dated maturities to lock in low rates. The Fund primarily purchased commercial paper (i.e., short-term, unsecured promissory notes sold by corporations to meet short-term debt obligations) in shorter maturities and government agency paper (fixed-income securities issued by government entities, such as Fannie Mae) in longer maturities, as corporate commercial paper yields continued to decline relative to agency securities and Treasury bills.

With the LIBOR (London Interbank Offered Rate, which is an interest rate used in the short-term international interbank market) interest rate curve flattening as the year progressed, the minimal yield advantage in longer-dated commercial paper issues did not, in most cases, justify the associated credit risk. The Fund's performance was enhanced by selectively adding high-quality, floating-rate notes that reset based on three-month LIBOR rates. By selecting the notes that reset every 90 days, we were able to take advantage of higher yields without overextending the weighted average maturity (the "WAM") of the Fund.

In general, the Fund's performance was adversely affected by historically low nominal yields, which forced the Fund to cut fees in order to avoid a negative net yield. The WAM of the Fund increased during the year as the near-term prospects of a Federal Reserve (the "Fed") rate hike dissipated.

The Fund maintained its position of being well diversified across industries and companies. The portfolio held an underweight position relative to the benchmark in U.S. Treasuries throughout most of 2009, as yields on these instruments continued to be very low in an environment where investors sought safety in U.S. government securities.

Subadviser outlook

The Securities and Exchange Commission (SEC) has adopted final rule changes applicable to money market funds that will be effective in 2010. Rule changes include lowering the maximum WAM from 90 to 60 days, requiring funds to maintain certain levels of overnight and weekly liquidity, and placing new limits on Tier-2 holdings (which are currently not allowed in the Fund's portfolio).

With the Fed on hold for the near future, conditions in 2010 should closely resemble the year-end 2009 market environment. We expect that low supply, low yields, and lots of available cash will keep rates low. The Fund's trading activity remains focused on searching for opportunities to reduce risk while finding attractive investments. Our objective for the future is to continue purchasing high-quality instruments and to remain well diversified across industries and security types.

MML Managed Bond Fund – Portfolio Manager Report

What is the investment objective of MML Managed Bond Fund, and who is the Fund's subadviser?

The Fund seeks to achieve as high a total rate of return on an annual basis as is considered consistent with the preservation of capital by normally investing at least 80% of its net assets in investment-grade fixed-income debt securities. The Fund's subadviser is Babson Capital Management LLC (Babson Capital).

How did the Fund perform during the 12 months ended December 31, 2009?

The Fund's Initial Class shares returned 10.21%, outperforming the 5.93% return of the Barclays Capital U.S. Aggregate Bond Index (the "benchmark"), an unmanaged index of fixed-rate investment-grade securities with at least one year to maturity, combining the Barclays Capital U.S. Treasury Bond Index, the Barclays Capital U.S. Government-Related Bond Index, the Barclays Capital U.S. Corporate Bond Index, and the Barclays Capital U.S. Securitized Bond Index.

For a discussion on the economic and market environment during the 12-month period ended December 31, 2009, please see the Economic and Market Review, beginning on page 3.

Subadviser discussion of factors that contributed to the Fund's performance

The Fund's performance relative to the benchmark for the year 2009 was particularly strong. The favorable results were driven primarily by certain portfolio strategies, such as the Fund's overweight position relative to the benchmark in corporate bonds, including high-yield bonds, as risk premiums contracted; a down-in-quality "tilt" into triple-B and cross-over credits (i.e., those bonds rated triple-B by one rating agency and double-B by another); an underweight position in Treasury/agency bond sectors, which generally lagged lower-quality investments in 2009; opportunistic trading in the agency pass-through sector; limited exposure to out-of-index collateralized debt obligation (CDO) and non-agency collateralized mortgage obligation (CMO) sectors, which had recovered sharply from previously distressed levels; and positive security selection in corporate and other non-Treasury bonds.

Conversely, certain portfolio strategies hampered the Fund's performance in 2009, including minimal exposure to sovereign/emerging market bonds (which performed well); holdings in certain issuers, such as CIT, which deteriorated sharply; and the Fund's yield-curve positioning, which hindered performance somewhat. (The yield curve is a graphical representation of bond yields with very short maturities to the longest available, with the curve indicating whether short-term rates are higher or lower than long-term rates.)

With respect to portfolio positioning, in the early part of the year, the Fund was quite conservative in light of the weak economic backdrop in the U.S. (specifically, the financials sector). As the year progressed, however, improving economic and overall market conditions encouraged investors to add risky assets. Consequently, positive technicals, stronger earnings, and a healthy new issue market drove a powerful rally in valuations across all bond sectors. During the year, we used better market conditions to reposition the Fund out of corporate and other non-Treasury bonds that had improved in price substantially, yet were still somewhat vulnerable from a credit perspective. We also cautiously moved the Fund to an overweight position in corporate and other non-Treasury bonds relative to Treasuries and agencies.

Subadviser outlook

In 2009, sector allocations and rotations were important performance drivers for the Fund. We expect that, in 2010, gains and/or loss avoidance will be impacted more by security selection. In the longer term, our view is that many significant wild cards remain, such as the Federal Reserve's exit strategy (from historically low interest rates), the U.S. dollar, and commercial real estate. There is a sense that serious fundamental challenges — such as high unemployment, real estate valuations, and the deleveraging (debt-reducing) consumer — will ultimately need to be resolved.

For now, however, the federal government's commitment to do "whatever it takes" continues to generate momentum towards a self-sustaining recovery. In the near term, we believe that improving economic data, corporate health, and positive momentum are likely to continue lifting asset prices higher. Our view is that the economy has entered one of those difficult transition stages which may well last well into 2010,

MML Managed Bond Fund – Portfolio Manager Report (Continued)

as investors await confirmation on future direction. Within this period, we believe volatility is likely to remain elevated, presenting increased opportunities for short-term, tactical trading; strong technical- or momentum-driven markets may linger longer than expected; and "non-fundamental" changes to companies or markets may unexpectedly and rapidly impact valuations, often negatively, reinforcing the need for prudent diversification and careful relative value analysis. (Examples of "non-fundamental" changes include corporate-bond tender offers, "amend-to-extend" deals in the loan business, U.S. Treasury changes to certain accounting rules for commercial mortgage-backed securities, the evolution of government support programs, and rating agency pronouncements.) With these views in mind, we have positioned the portfolio to weather the uncertainties and challenges that may lie ahead for fixed-income investors.

MML Blend Fund – Portfolio Manager Report

What is the investment objective of MML Blend Fund, and who is the Fund's subadviser?

The Fund seeks to achieve as high a level of total rate of return over an extended period of time as is considered consistent with prudent investment risk and the preservation of capital. The Fund's portfolio consists of three segments: Money Market Segment, Bond Segment and Equity Segment. The Fund adjusts the mix of investments among these three market segments based on the judgment of the Fund's subadviser about each segment's potential for returns related to the corresponding risk. The Fund's subadviser is Babson Capital Management LLC (Babson Capital).

How did the Fund perform during the 12 months ended December 31, 2009?

The Fund's Initial Class shares returned 20.55%, trailing the 26.46% return of the S&P 500^® Index, a widely recognized, unmanaged index representative of common stocks of larger capitalized U.S. companies. Conversely, the Fund outpaced the 5.93% return of the Barclays Capital U.S. Aggregate Bond Index (the "bond benchmark"), an unmanaged index of fixed-rate investment-grade securities with at least one year to maturity, combining the Barclays Capital U.S. Treasury Bond Index, the Barclays Capital U.S. Government-Related Bond Index, the Barclays Capital U.S. Corporate Bond Index, and the Barclays Capital U.S. Securitized Bond Index. Finally, the Fund underperformed the 23.35% return of the Lipper Balanced Fund Index (the "blend benchmark"), an unmanaged, equally weighted index of the 30 largest mutual funds within the Lipper Balanced Category.

Subadviser discussion of factors that contributed to the Fund's performance

With respect to the equity component of the Fund, we positioned the portfolio well from an asset allocation standpoint, buying equities very close to the low of the market. As the year began, the Fund held an underweight position relative to the blend benchmark in its equity portfolio. Valuations, however, kept improving as the market sold off during the first quarter of 2009. During this time, we bought stocks and, in fact, increased the Fund's position in equities in February — finally moving from an underweight position in equities to an overweight one in late March.

Within the equity portfolio, however, our models struggled in 2009, as the macro outlook overshadowed stock selection. The stocks that performed the best during the year had negative earnings, poor balance sheets, high beta, and smaller capitalizations. These were the companies that had the most to gain from an economic recovery. The factor weights in our models change to respond to factor effectiveness. In 2009, the factor that we needed to emphasize was beta, and we did that by holding an overweight position in the equity portfolio from an asset allocation standpoint. This allowed us to follow our disciplined approach in stock selection.

Turning to the Fund's fixed-income segment, the Fund held an overweight position relative to the blend benchmark in this portfolio component early in the year. We moved the Fund to an underweight position in fixed-income when we increased holdings in equities (in March) due to the thesis that the equity market is more levered to economic recovery. The Fund continued to maintain its underweight position in fixed-income assets throughout the balance of 2009, as the risk of rising interest rates remained, in our view, quite strong.

Within the fixed-income portfolio, we held an overweight position in corporate bonds relative to the bond benchmark, as there appeared to be tremendous value in this market segment after the market meltdown. Financial firms had access to cheap government liquidly (namely, a 0.1% federal funds rate), but were hampered by risk-based capital standards that limited where they could deploy that capital. Corporate bonds were compelling, as they gave exposure to a cheaply valued asset, while simultaneously allowing investors to adhere to their risk-based capital standards. The same applied to U.S. government debt, which is triple-A rated. Firms could leverage their holdings in these highly rated securities and still be considered well capitalized, a moniker that had increased in importance after the meltdown. These factors led to corporate credits' posting considerable excess returns over Treasuries.

MML Blend Fund – Portfolio Manager Report (Continued)

Subadviser outlook

As financial institutions become better capitalized, in our view, they'll no longer have a disproportionate need to hold highly rated debt securities. Consequently, they may see some of the highest-rated securities in the triple-A and double-A range as overvalued. The ability and desire to sell these securities may lead them to move out of these investments into other risk assets. The degree to which financial institutions embrace risk will depend on how long the Federal Reserve keeps short-term interest rates at essentially zero — and how long the U.S. government is willing to keep propping up the economy with huge transfer payments.

The equity market is still characterized by poor valuations and weak fundamentals, but abundant liquidity. We believe that it is likely that volatility will pick up in 2010, as uncertainty about the timing of the end of low interest rates and the end of government stimulus becomes more of a focus.

Investors should note that the Fund is a professionally managed mutual fund, while the S&P 500 Index, the Barclays Capital U.S. Aggregate Bond Index and the Lipper Balanced Fund Index are unmanaged, do not incur expenses, and cannot be purchased directly by investors. Investors should read the Fund's prospectus with regard to the Fund's investment objective, risks and charges and expenses in conjunction with these financial statements. The Fund's return reflects changes in the net asset value per share without the deduction of any product charges (e.g., cost of insurance, mortality and expense risk charges, administrative fees, and CDSL). The inclusion of these charges would have reduced the performance shown here.

MML Equity Fund – Portfolio Manager Report

What is the investment objective of MML Equity Fund, and who are the Fund's subadvisers?

The Fund's primary objective is to achieve a superior total rate of return over an extended period of time, from both capital appreciation and current income. Its secondary objective is the preservation of capital when business and economic conditions indicate that investing for defensive purposes is appropriate. The Fund's two subadvisers are OppenheimerFunds, Inc. (OFI), which managed approximately 74% of the Fund's portfolio; and AllianceBernstein L.P. (AllianceBernstein), which was responsible for approximately 26% of the Fund's portfolio, as of December 31, 2009.

How did the Fund perform during the 12 months ended December 31, 2009?

The Fund's Initial Class shares returned 30.71%, outpacing the 19.69% return of the Russell 1000^® Value Index (the "benchmark"), an unmanaged index consisting of those Russell 1000 securities (representing the 1,000 largest U.S. companies, based on market capitalization) with greater-than-average value orientation that tend to exhibit lower price-to-book ratios and forecasted growth values than securities in the growth universe.

For a discussion on the economic and market environment during the 12-month period ended December 31, 2009, please see the Economic and Market Review, beginning on page 3.

Subadviser discussion of factors that contributed to the Fund's performance

With respect to the Fund's OFI component, stock selection accounted for the vast majority of the portfolio's relative outperformance, although sector allocations also contributed. Overall, the portfolio outperformed the benchmark in seven of the 10 economic sectors — largely due to superior holdings in materials, information technology, consumer discretionary, and industrials. Factors that detracted from the portfolio's full-year results included holdings in the telecommunication services sector, with the detrimental effects reduced somewhat by a beneficial underweight position relative to the benchmark in this poor-performing sector. Similarly, the portfolio fell short in the utilities sector. The consumer staples sector proved to be the greatest hindrance for the year, as disappointing stock results combined with a detrimental overweight position.

Despite being politically charged and the sector with the greatest uncertainty throughout 2009, financials added the most value to the portfolio on a relative basis. Favorable stock selection within this sector was well rewarded, as portfolio holdings in SLM (Sallie Mae), Morgan Stanley, Goldman Sachs, and MetLife excelled. As expectations took hold for a bottom — and eventual rebound — in global gross domestic product (GDP) growth, sectors such as industrials, materials, and information technology vaulted higher, recovering a large percentage of the losses of the prior year. (GDP reflects the total value of goods and services produced in the United States.)

For the Fund's AllianceBernstein component, the largest contributions came from the portfolio's financial and media holdings. In the financials sector, holdings Prudential and Deutsche Bank contributed. Media holding News Corp. rose on strong advertising trends and an announcement that its Fox television network would seek higher fees from cable and satellite operators over the coming years as existing agreements expire. Fellow media company CBS announced third-quarter results that beat expectations and reaffirmed its full-year outlook. The company also successfully refinanced a $2 billion credit facility, which erased concerns about lingering liquidity issues.

On the downside, the portfolio's underweight position and stock selection in industrial resources was a major drag on returns — due mostly to the Fund's avoidance of strong-performing chemical, paper, and copper producers, which rose with the spike in commodity prices. An underweight position in the financials sector also detracted from the portfolio's full-year results.

Subadviser outlook

Despite some encouraging economic reports and a massive rally in the equity markets since March 9, 2009 (the equity market "bottom"), we still foresee volatile times ahead for equities. Equity markets, and the U.S. economy in general, have yet to deal with many of the problems created by the recent financial crisis. Our view is that large and as of yet unrecognized losses are still to come. Banks could see tough times from areas such as commercial real estate, the economy still suffers stubbornly high unemployment, and the U.S. has issued high levels of government debt. While the timeline is uncertain, we nevertheless believe that the U.S. economy has the strength and resilience to overcome most obstacles that may emerge in the coming months.
