Morgan Stanley Variable Investment Series

Letter to the Shareholders n June 30, 2010

Dear Shareholder,

The first half of 2010 was marked by slowing recovery in the economy and turbulence in the financial markets. Recent gross domestic product (GDP) data showed that the U.S. economy continued to expand in the first quarter of the year, albeit at a slower pace than the last quarter of 2009, and many of the characteristics of recovery remained in evidence. For example, industrial production, capacity utilization and purchasing manager surveys all pointed to sustained levels of global GDP growth. That said, investors remained concerned about the economy's future path. The government's fiscal stimulus packages did help to stabilize the housing market and consumer spending, but fears persisted about the potential impact on the economy as these programs are phased out. Furthermore, the labor market remained weak in spite of modest improvements in the latter months of the period.

After a relatively calm first quarter, financial markets turned choppy in the second quarter as investors focused on the unfolding sovereign debt crisis in Europe and weaker-than-expected economic data, particularly employment in the U.S. In emerging markets, central banks stepped up the movement toward the normalization of monetary policy. China's central bank announced a more flexible exchange rate policy while Chile's central bank surprised observers with a larger-than-expected 50 basis point increase in that country's key policy rate.

Domestic Equity Overview

Over the six-month review period, the U.S. equity market reversed course from the rally that had begun in March of 2009 to finish the period with a return of – 6.66%, as measured by the S&P 500^® Index. Volatility returned to the markets, especially in the second quarter of 2010, as investor confidence in the global economic recovery fell. After several consecutive quarters of improving economic data in the U.S., employment and housing reports began to disappoint expectations, fueli ng concerns about the potential for a double-dip recession in the U.S. even as investors became increasingly concerned about markets elsewhere.

Both growth and value stocks lost ground during the period (as measured by the Russell 1000^® Growth and Value Indexes, respectively), though overall small capitalization companies outperformed larger-caps (as measured by the Russell 2000^® and S&P 500^® Indexes, respectively). All sectors of the S&P 500^® Index declined for the six month period, but performance varied widely. The industrial sector lost the least value, followed by the consumer discretionary and consumer staples sectors. The materials sector was the worst performer, followed closely by the energy sector, which suffered amidst the ongoing oil spill in the Gulf of Mexico.

Fixed Income Overview

As with equities, the first quarter of 2010 was overall a good period for fixed income assets, which were supported by a positive macroeconomic backdrop of benign economic data and supportive monetary policy. However, bond markets became more volatile in the second quarter on mounting fiscal and political concerns. Against this backdrop, government bonds continued to be regarded as "safe haven" assets, leading U.S. Treasury yields to decline across the yield curve. With regard to agency debt, yield spreads (a measure of the compensation demanded by investors to assume credit risk) were relatively unchanged on intermediate maturities but widened somewhat on long maturities.

In other major bond market sectors, yield spreads on agency mortgage-backed securities (MBS) widened by approximately 10 basis points over the course of the period. For the period, 15-year mortgages outperformed 30-year mortgages and higher coupons outperformed lower coupons. Corporate credit spreads also widened during the period as credit concerns returned, leading high yield to underperform investment grade credit (as measured by the Barclays Capital U.S. Corporate High Yield – 2% Issuer Cap Index and Barclays Capital Corporate Bond Index, respectively). The best performing sectors in the investment grade market were real estate investment trusts (REITs), brokers and technology, while the worst performers were energy, communications and banking.

The money markets continued to gain stability from the expansion of the Federal Reserve's balance sheet. However, notable announcements by the Federal Reserve and Treasury beginning in February indicated that the extraordinary liquidity measures provided by emergency government actions were coming to an end and efforts to begin draining excess reserves from the banking system would soon be underway. Also in February, the Securities Exchange Commission (SEC) published its final Money Market Fund Reform rules, which became effective in May.

International Equity Overview

International equity markets were increasingly volatile during the period as investors digested a spate of political and fiscal troubles in developed markets. In early 2010, sovereign debt woes in Greece reached a boiling point, leading to fears that similarly indebted countries elsewhere in Europe could create even greater danger for the global financial system. Germany ultimately led the rest of Europe to create a bailout fund, helping assuage investors' immediate concerns, but long-term worries remained. Equity markets in Asia also struggled in the wake of China's decision to enact mildly restrictive measures to cool its economy's heated growth (particularly in the property sector), triggering concerns about the potential for a slowdown

in Chinese demand. Against this backdrop, international developed markets, as represented by the Morgan Stanley Capital International (MSCI) EAFE Index, finished the period with a double-digit decline.

Emerging markets as a whole also lost ground during the period, though performance varied by region and by country. Peripheral European markets were hit hard by concerns over fiscal viability on the Continent, with Hungary and Poland performing especially poorly. Performance was more mixed in Asia, with China's economic policy and steep market losses continuing to dominate headlines in the region. Latin American shares also generally declined, though as in Asia, performance was widely dispersed by country. The two best-performing emerging markets for the six-month period ended June 30, 2010 were Colombia and Indonesia.

Aggressive Equity Portfolio

For the six-month period ended June 30, 2010, Variable Investment Series – Aggressive Equity Portfolio Class X shares produced a total return of – 8.13%, underperforming the Russell 3000^® Growth Index (the "Index"),¹ which returned – 7.25%. For the same period, the Portfolio's Class Y shares returned – 8.22%. Past performance is no guarantee of future results.

The performance of the Portfolio's two share classes varies because each has different expenses. The Portfolio's total returns assume the reinvestment of all distributions but do not reflect the deduction of any charges by your insurance company. Such costs would lower performance.

Stock selection in materials and processing had the largest negative effect on relative performance for the period. The sole position in the sector was in the fertilizer industry. Both stock selection and a sector overweight in financial services hampered returns. Within the sector, financial data and systems was the leading detracting industry. In the health care sector, stock selection in health care services also detracted.

Although the Portfolio underperformed the Index, there were areas that contributed to relative performance. Stock selection in technology had the largest positive effect, with the leading contributor in the computer services software and systems industry. Stock selection in producer durables was also positive, especially in the commercial services industry, although an underweight to the sector did detract. The Portfolio's lack of exposure to the utilities industry was also advantageous.

Capital Opportunities Portfolio

For the six-month period ended June 30, 2010, Variable Investment Series – Capital Opportunities Portfolio Class X shares produced a total return of – 7.51%, underperforming the Russell 3000^® Growth Index (the "Index"),² which returned – 7.25%. For the same period, the Portfolio's Class Y shares returned – 7.63%. Past performance is no guarantee of future results.

Stock selection in materials and processing had the largest negative effect on relative performance for the period. The sole position in the sector was in the fertilizer industry. Both stock selection and a sector overweight in financial services were disadvantageous to returns, particularly the Portfolio's exposure to the financial data and systems industry. Stock selection in health care services also hindered relative performance.

Although the Portfolio underperformed the Index, there were areas that positively contributed to relative performance. Stock selection in technology had the largest positive effect. Within the sector, the largest contributor was in the consumer software and service industry group. Stock selection in producer durables also supported returns, especially in the commercial services industry, although an underweight to the sector did detract. The Portfolio's lack of exposure to the utilities industry was also advantageous.

There is no guarantee that any sectors mentioned will continue to perform as discussed above or that securities in such sectors will be held by the Portfolio in the future.

European Equity Portfolio

For the six-month period ended June 30, 2010, Variable Investment Series – European Equity Portfolio Class X shares produced a total return of – 17.16%, underperforming the MSCI Europe Index (the

"Index"),³ which returned – 16.72%. For the same period, the Portfolio's Class Y shares returned – 17.27%. Past performance is no guarantee of future results.

Key detractors from relative returns included stock selection in France and the United Kingdom, stock selection and an overweight allocation to Greece, and an underweight allocation to Denmark. Stock selection in financials, materials and health care also hindered relative returns. Positive contributors to relative returns included stock selection in Germany, stock selection and an overweight in Switzerland, stock selection and an underweight allocation to Italy, and an underweight allocation to Spain. Stock selection in industrials, consumer staples and telecommunications also supported relative returns, as did an underweight allocation to utilities.

European banks remain under pressure from the market due to the ongoing concerns over their lending exposure to struggling regional governments. We believe that the upcoming stress tests of over 91 European banks should help to draw a line in the sand between solid, well-capitalized banks and more fragile and weaker names. In this sector, the Portfolio is invested in what we believe are more solid names, many of which are pricing in worst-case scenarios in spite of their financial strength, as the market has differentiated little between banks so far.

The outlook for the European economy has improved, and global economic data, including in Europe, is rebounding from its lows and remains supportive, in our view. We expect that the European economy should be a major beneficiary of a global recovery, with its high exposure to emerging markets and exports boosted by a weak currency. We see recent weakness in the market as an opportunity to selectively add stocks to the Portfolio, as European valuations are cheap compared to historical levels. Current equity valuations are now pricing a low-growth scenario for Europe, which we believe seems to be the most likely scenario for the next few years. Nevertheless, we believe that European equities are well positioned to be a positive surprise for 2010. Our investment approach remains the same. We continue to seek high quality companies with high earnings visibility and predictability, stable and strong cash flow, and low levels of debt trading at attractive valuations.

There is no guarantee that any sectors mentioned will continue to perform as discussed above or that securities in such sectors will be held by the Portfolio in the future.

Global Infrastructure Portfolio

For the six-month period ended June 30, 2010, Variable Investment Series – Global Infrastructure Portfolio Class X shares produced a total return of – 12.15%, underperforming the Dow Jones Brookfield Global Infrastructure Index (the "Index"),⁴ which returned – 7.45%, and the S&P Global BMI Index⁵ which returned – 8.26% , and outperforming the S&P 500^® Utilities Index/S&P Global Infrastructure Index,⁶ which returned – 13.05%. For the same period, the Portfolio's Class Y shares returned – 12.10%. Past performance is no guarantee of future results.

Portfolio performance over this time-period reflects a number of changes coincident with our assumption of portfolio management responsibilities at the end of March 2010, the two most important being (1) a change in the Portfolio's sector benchmark to the Dow Jones Brookfield Global Infrastructure Index and (2) a shift in Portfolio holdings to reflect our fundamental, value-driven investment strategy. Holdings in the Portfolio now generally reflect companies with "core" infrastructure characteristics such as asset ownership/control, high barriers to entry, and cash flow stability. Furthermore, companies with exposure to commodity price fluctuations have been significantly reduced. While these changes have had some marginal negative impact on short-term performance, we anticipate the changes in Portfolio strategy and company constituents will provide investors with a more attractive risk/return profile over the long-run.

We are committed to our core investment philosophy as an infrastructure value investor. This results in the ownership of stocks which we believe provide infrastructure exposure at the best valuation relative to their

The Index intends to measure all sectors of the infrastructure market. The Index was first published in July 2008; however, back-tested hypothetical performance information is available for this Index since December 31, 2002. Returns are calculated using the return data of the S&P Global BMI Index through December 31, 2002 and the return data of the Dow Jones Brookfield Global Infrastructure Index for periods thereafter. It is not possible to invest directly in an index. The Portfolio's secondary benchmark was changed in March 2010 from the S&P 500 Utilities Index/S&P Global Infrastructure Index t o the Dow Jones Brookfield Global Infrastructure Index to more accurately reflect the Portfolio's investable universe.

underlying assets and growth prospects. Our research led us to an overweighting in the Portfolio to the communications, toll roads, and diversified sectors and an underweighting to companies in the European regulated utilities, transmission and distribution, ports and water sectors. The Portfolio's overweight position in communications reflected our belief that certain companies within the sector were trading at meaningful discounts to intrinsic value and possessed good growth prospects not dependent on a strong global macroeconomic recovery. For the toll road and diversified sectors, the Portfolio's overweight positions, in large part, reflected investments in companies domiciled in southern Europe, but with much more diversified geographic operating exposure. These companies were trading at what we believed to be significant discounts to intrinsic value that were unjustified given the companies' cash flow characteristics and a bility to withstand long periods of capital markets instability, such as what was experienced in Europe through the first half of 2010.

There is no guarantee that any sectors mentioned will continue to perform as discussed above or that securities in such sectors will be held by the Portfolio in the future.

Income Plus Portfolio

For the six-month period ended June 30, 2010, Variable Investment Series – Income Plus Portfolio Class X shares produced a total return of 4.52%, underperforming the Barclays Capital U.S. Corporate Index (the "Index"),⁷ which returned 5.79%. For the same period, the Portfolio's Class Y shares returned 4.35%. Past performance is no guarantee of future results.

The Portfolio maintained an underweight to more defensive sectors within the corporate credit market, namely aerospace and defense, health care and utilities. This positioning detracted from relative performance as recent corporate spread widening was more pronounced in economically sensitive sectors, where the Portfolio held more overweight positions. Additionally, macroeconomic concerns drove bank spreads wider from period lows in April, reducing performance of the Portfolio's overweight in banks. However, the Portfolio's overweight in REITs supported relative returns, as did its underweight in industrial credits.

Letter to the Shareholders n June 30, 2010 continued

Overall, within the corporate credit market, we continued to focus on senior securities with intermediate maturities, and those issued by companies where we believe continued improvement in credit fundamentals will lead to spread tightening.

There is no guarantee that any sectors mentioned will continue to perform as discussed above or that securities in such sectors will be held by the Portfolio in the future.

Limited Duration Portfolio

For the six-month period ended June 30, 2010, Variable Investment Series – Limited Duration Portfolio Class X shares produced a total return of 1.30%, underperforming the Barclays Capital U.S. Credit Index (1-5 Year) (the "Index"),⁸ which returned 3.20%. For the same period, the Portfolio's Class Y shares returned 1.29%. Past performance is no guarantee of future results.

Overall, within the corporate credit market, we continued to focus on relatively senior securities with intermediate maturities, and on issues of companies whose creditworthiness in our view would not be materially hurt by a cyclical decline in earnings. At the sector level, the Portfolio maintained an underweight to more defensive sectors, namely aerospace and defense, health care and utilities. This positioning detracted from relative performance as these sectors outperformed other sectors of the credit market. However, the Portfolio was slightly underweight corporate credit relative to the Index, which was additive to performance. The underweight was due to an allocation to asset-backed securities (or ABS, a sector not represented in the Index), which was also advantageous as ABS outperformed corporate credit for the period.

The Portfolio maintained a lower duration (or interest rate sensitivity) than that of the Index. This positioning hindered relative performance as it kept the Portfolio from more fully participating in the rally in Treasury prices as yields declined.

There is no guarantee that any sectors mentioned will continue to perform as discussed above or that securities in such sectors will be held by the Portfolio in the future.

Money Market Portfolio

An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although money market funds seek to preserve the value of an investment at $1.00 per share, it is possible to lose money by investing in such funds.

As of June 30, 2010, the Money Market Portfolio had net assets of more than $140 million with an average portfolio maturity of 17 days. For the seven-day period ended June 30, 2010, the Portfolio's Class X shares provided an effective annualized yield of 0.01% (subsidized) and – 0.34% (non-subsidized) and a current yield of 0.01% (subsidized) and – 0.34% (non-subsidized), while its 30-day moving average yield for June was 0.01% (subsidized) and – 0.33% (non-subsidized). Yield quotations more closely reflect the current earnings of the Portfolio. The non-subsidized yield reflects what the yield would have been had a fee and/or expense waiver not been in place during the period shown. For the six-month period ended June 30, 2010, the Portfolio's Class X shares returned 0.01%. Past performance is no guarantee of future results.

For the seven-day period ended June 30, 2010, the Portfolio's Class Y shares provided an effective annualized yield of 0.01% (subsidized) and – 0.59% (non-subsidized) and a current yield of 0.01% (subsidized) and – 0.59% (non-subsidized), while its 30-day moving average yield for June was 0.01% (subsidized) and – 0.58% (non-subsidized). Yield quotations more closely reflect the current earnings of the Portfolio. The non-subsidized yield reflects what the yield would have been had a fee and/or expense waiver not been in place during the period shown. For the six-month period ended June 30, 2010, the Portfolio's Class Y shares returned 0.01%. Past performance is no guarantee of future results.

During the reporting period, we continued to place a strong emphasis on purchasing high quality corporate, financial, and banking obligations. We focused on maintaining high levels of liquidity and a short weighted average maturity to guard against the uncertainty caused by volatility in the financial markets. Our strategy in managing the Portfolio remained consistent with our long-term focus on capital preservation and very high liquidity, and as in the past, we adhered to a conservative approach. We continue to review all eligible securities on our purchase list to ensure that they continue to meet our high standards of minimal credit risk.

There is no guarantee that any sectors mentioned will continue to perform as discussed above or that securities in such sectors will be held by the Portfolio in the future.

Strategist Portfolio

For the six-month period ended June 30, 2010, Variable Investment Series – Strategist Portfolio Class X shares produced a total return of – 4.31%, outperforming the S&P 500^® Index (the "Index"),⁹ which returned – 6.66%, and underperforming the Barclays Capital U.S. Government/Credit Index,¹⁰ which returned 5. 49%. For the same period, the Portfolio's Class Y shares returned – 4.40%. Past performance is no guarantee of future results.

Strategist Portfolio's flexible investment approach allows investment across stocks, bonds, cash and other investment classes. To determine the specific allocation among asset classes throughout the period, we rigorously evaluate a comprehensive array of quantitative and qualitative factors. The quantitative analysis comprises an extensive "top-down" asset class review of many macroeconomic variables, with primary focus on three core factors: monetary policy and its impact on liquidity, inflation trends and corporate profitability. A second, more qualitative process then broadens the analysis to determine which individual sectors and industries would offer the best opportunities, in our view, given the macroeconomic climate. Individual holdings are then selected to provide desired exposure to asset classes and sectors.

The Portfolio's target allocation shifted slightly during the six-month period under review, as the management team reduced cash reserves and raised the Portfolio's exposure to equities. As of June 30, 2010, 62.0% of total net assets were allocated to equities (a slightly higher weight than an average balanced fund's 60.0%), 22.4% of total net assets were allocated to fixed income instruments (a significantly lower allocation than an average balanced fund's 35.0% weighting), and the remaining 15.6% of assets were allocated to cash equivalents (higher than an average balanced fund's 10.0% exposure).

The first half of 2010 continued to exhibit many of the characteristics of recovery that began during the latter half of 2009. For example, industrial production, capacity utilization and purchasing manager surveys all pointed to sustained levels of global GDP growth. For the developed nations (primarily the U.S., the

United Kingdom, Europe and Japan), the recovery looked rather "typical" of post-World War II cycles, as the massive inventory depletion during the recession led to product restocking and restarting of idle capacity. Also typical, deflation took hold as idle capacity was absorbed before new capacity investments could be made. This issue appeared most acute in the U.S. labor market, where sidelined workers found few new job opportunities as companies first sought to leverage existing employees prior to taking on new, permanent costs.

In the emerging market economies, growth rates fell in 2008 and early 2009, but generally remained positive. In most cases, traditional monetary and stimulative policies reignited growth in late 2009 and 2010 to date, as China, India, greater Asia and Latin America all resumed pre-crisis expansions. As the first half of 2010 came to an end, many of these regions were raising interest rates in an attempt to control rising inflation, a by-product of this rapid growth.

During the period under review, we increased cyclical sector exposures in both the equity and fixed income portions of the Portfolio. Within the equity portfolio, allocations to the industrial and basic materials sectors increased, while allocations to information technology, financials, consumer discretionary and telecommunications were reduced. A long-standing bias toward large capitalization, higher quality companies continued, as did the Portfolio's tilt toward U.S. exposures. Two international, tactical investments were made during the period, both via exchange-traded funds (ETFs), in Russian equities and the euro.

The fixed income component of the Portfolio shifted during the period under review as well, as cash positions were reduced moderately in order to fund purchases in municipal securities and agency debt. As of June 30, 2010, the Portfolio's cash exposure had been reduced from approximately 5.0% of fixed income assets to roughly 2.0%. Exposures to municipal credits rose from approximately 0.1% of fixed income assets to 1.1%, while agency exposure increased from 15.6% of fixed income assets to 16.0%.

At period-end, U.S. government-issued securities represented approximately 40.0% of overall fixed income assets, while corporate credits represented approximately 41.0% of the total. The balance of the Portfolio was distributed among various asset-backed securities.

There is no guarantee that any sectors mentioned will continue to perform as discussed above or that securities in such sectors will be held by the Portfolio in the future.

Expense Example n June 30, 2010

As a shareholder of the Portfolio, you incur two types of costs: (1) insurance company charges; and (2) ongoing costs, including advisory fees; distribution and service (12b-1) fees; and other Portfolio expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Portfolio and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 01/01/10 – 06/30/10.

Actual Expenses

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

Hypothetical Example for Comparison Purposes

The second line of the table below provides information about hypothetical expenses based on the Portfolio's actual expense ratio and an assumed rate of return of 5%per year before expenses, which is not the Portfolio'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 cost of investing in the Portfolio 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 insurance company charges. Therefore, the second line of the table is useful in comparing ongoing costs, and will not help you determine the relative total cost of owning different funds. In addition, if these insurance company charges were included, your costs would have been higher.

Investment Advisory Agreement Approval n June 30, 2010

Nature, Extent and Quality of Services

The Board reviewed and considered the nature and extent of the investment advisory services provided by the Investment Adviser (as defined herein) under the advisory agreement, including portfolio management, investment research and equity and fixed income securities trading. The Board reviewed similar information and factors regarding the Sub-Advisers (as defined herein), to the extent applicable. The Board also reviewed and considered the nature and extent of the non-advisory, administrative services provided by the Administrator (as defined herein) under the administration agreement, including accounting, clerical, bookkeeping, compliance, business management and planning, and the provision of supplies, office space and utilities at the Investment Adviser's expense. (The Investment Adviser, Sub-Advisers and Administrator together are referred to as the "Adviser" and the advisory, sub-advisory and administration agreements tog ether are referred to as the "Management Agreement.") The Board also compared the nature of the services provided by the Adviser with similar services provided by non-affiliated advisers as reported to the Board by Lipper, Inc. ("Lipper").

The Board reviewed and considered the qualifications of the portfolio managers, the senior administrative managers and other key personnel of the Adviser who provide the administrative and advisory services to the Portfolios. The Board determined that the Adviser's portfolio managers and key personnel are well qualified by education and/or training and experience to perform the services in an efficient and professional manner. The Board concluded that the nature and extent of the advisory and administrative services provided were necessary and appropriate for the conduct of the business and investment activities of the Portfolios and supported its decision to approve the Management Agreement.

Performance, Fees and Expenses of the Portfolios

The Board reviewed the performance, fees and expenses of the Portfolios compared to their peers, as determined by Lipper, and to appropriate benchmarks where applicable. The Board discussed with the Adviser the performance goals and the actual results achieved in managing the Portfolios. When considering a fund's performance, the Board and the Adviser place emphasis on trends and longer-term returns (focusing on one-year, three-year and five-year performance, as of December 31, 2009, as applicable). When a fund underperforms its benchmark and/or its peer group average, they discuss the causes of such underperformance and, where necessary, they discuss specific changes to investment strategy or investment personnel.

Performance

The Board noted that the performance of the Limited Duration and Money Market Portfolios was below the peer group averages for the one-, three- and five-year periods.

The Board noted that the performance of the Aggressive Equity, Capital Opportunities and Income Plus Portfolios was better than the peer group averages for the one-, three- and five-year periods.

Morgan Stanley Variable Investment Series

Investment Advisory Agreement Approval n June 30, 2010 continued

The Board noted that the performance of the Global Infrastructure Portfolio was better than its peer group average for the three- and five-year periods but below its peer group average for the one-year period.

The Board noted that the performance of the European Equity Portfolio was better than its peer group average for the three-year period but below its peer group average for the one- and five-year periods.

The Board noted that the performance of the Strategist Portfolio was better than its peer group average for the one- and five-year periods but below its peer group average for the three-year period.

Performance Conclusions

With respect to the European Equity, Limited Duration and Money Market Portfolios, after discussion, the Board concluded that performance was acceptable.

With respect to the Aggressive Equity, Capital Opportunities, Global Infrastructure, Income Plus and Strategist Portfolios, after discussion, the Board concluded that performance was competitive with the peer group averages.

Fees and Expenses

The Board members discussed with the Adviser the level of the advisory and administration fees (together, the "management fee") for the Portfolios relative to comparable funds advised by the Adviser and compared to their peers as determined by Lipper. In addition to the management fee, the Board also reviewed the Portfolios' total expense ratios.

The Board noted that the management fee and total expense ratio for the Aggressive Equity Portfolio were higher than its peer group average.

The Board noted that the management fees and total expense ratios for the Capital Opportunities, European Equity, Income Plus, Limited Duration and Strategist Portfolios were lower than the peer group averages.

The Board noted for the Money Market Portfolio that while the management fee was higher than its peer group average, the total expense ratio was lower than its peer group average.

The Board noted for the Global Infrastructure Portfolio that while the management fee was lower than its peer group average, the total expense ratio was higher but close to its peer group average.

Fee and Expense Conclusions

With respect to the Money Market Portfolio, after discussion, the Board concluded that (i) the management fee, although higher than its peer group average, was acceptable given the quality and nature of services provided, and (ii) the total expense ratio was competitive with its peer group average.

Morgan Stanley Variable Investment Series

Investment Advisory Agreement Approval n June 30, 2010 continued

With respect to Capital Opportunities, European Equity, Global Infrastructure, Income Plus, Limited Duration and Strategist Portfolios, after discussion, the Board concluded that the management fees and total expense ratios were competitive with the peer group averages.

With respect to the Aggressive Equity Portfolio, after discussion, the Board concluded that the the management fee and total expense ratio were acceptable given the quality and nature of services provided.

Economies of Scale

The Board considered the size and growth prospects of the Portfolios and how that relates to the Portfolios' total expense ratios and particularly the Portfolios' management fee rates (which, for all the Portfolios except Limited Duration, include one or more breakpoints). In conjunction with its review of the Adviser's profitability, the Board discussed with the Adviser how a change in assets can affect the efficiency or effectiveness of managing the Portfolios and whether the management fee level is appropriate relative to current and projected asset levels and/or whether the management fee structure reflects economies of scale as asset levels change. The Board has determined that its review of the actual and potential economies of scale of each Portfolio supports its decision to approve the Management Agreement.

Profitability of the Adviser and Affiliates

The Board considered information concerning the costs incurred and profits realized by the Adviser and its affiliates during the last year from their relationship with the Portfolios and during the last two years from their relationship with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost allocation methodology used to determine the profitability of the Adviser and affiliates. The Board has determined that its review of the analysis of the Adviser's expenses and profitability supports its decision to approve the Management Agreement.

Other Benefits of the Relationship

The Board considered other benefits to the Adviser and its affiliates derived from their relationship with the Portfolios and other funds advised by the Adviser. These benefits may include, among other things, "float" benefits derived from handling of checks for purchases and sales, research received by the Adviser generated from commission dollars spent on funds' portfolio trading and fees for distribution and/or shareholder servicing. The Board reviewed with the Adviser each of these arrangements and the reasonableness of the Adviser's costs relative to the services performed. The Board has determined that its review of the other benefits received by the Adviser or its affiliates supports its decision to approve the Management Agreement.

Morgan Stanley Variable Investment Series

Investment Advisory Agreement Approval n June 30, 2010 continued

Resources of the Adviser and Historical Relationship Between the Portfolios and the Adviser

The Board considered whether the Adviser is financially sound and has the resources necessary to perform its obligations under the Management Agreement. The Board also reviewed and considered the historical relationship between the Portfolios and the Adviser, including the organizational structure of the Adviser, the policies and procedures formulated and adopted by the Adviser for managing the Portfolios' operations and the Board's confidence in the competence and integrity of the senior managers and key personnel of the Adviser. The Board concluded that the Adviser has the financial resources necessary to fulfill its obligations under the Management Agreement and that it is beneficial for the Portfolios to continue their relationship with the Adviser.

Other Factors and Current Trends

The Board considered the controls and procedures adopted and implemented by the Adviser and monitored by the Fund's Chief Compliance Officer and concluded that the conduct of business by the Adviser indicates a good faith effort on its part to adhere to high ethical standards in the conduct of the Fund's business.

General Conclusion

After considering and weighing all of the above factors, the Board concluded that it would be in the best interest of each Portfolio and its shareholders to approve renewal of the Management Agreement for another year. In reaching this conclusion the Board did not give particular weight to any single factor referenced above. The Board considered these factors over the course of numerous meetings, some of which were in executive session with only the Independent Board members and their counsel present. It is possible that individual Board members may have weighed these factors differently in reaching their individual decisions to approve the Management Agreement.

On June 1, 2010, Invesco Ltd., a leading independent global investment management company, completed its purchase of substantially all of the retail asset management business of Morgan Stanley Investment Management (the "Transaction"). In contemplation of the Transaction, the Trustees of the Fund approved an Agreement and Plan of Reorganization (the "Reorganization") with respect to the High Yield, Income Builder, Dividend Growth, Global Dividend and S&P 500 Index Portfolios (each "affected Portfolio"), pursuant to which substantially all of the assets of each affected Portfolio would be combined with those of a newly organized mutual fund advised by an affiliate of Invesco Ltd. (the "New Fund"). On May 11, 2010, the Reorganization was approved by the shareholders of each affected Portfolio at a special meeting of shareholders. On June 1, 2010, the Reorganization was completed and shareholders of each affected Portfolio rece ived shares of the New Fund in exchange for their shares of each affected Portfolio. Accordingly, the financial statements of each affected Portfolio are no longer contained in this report but may be found in the report of their corresponding New Funds.

The following is a summary of significant accounting policies:

A. Valuation of Investments — Money Market: Portfolio securities are valued at amortized cost, which approximates market value, in accordance with Rule 2a-7 under the Act. All remaining Portfolios: (1) an equity portfolio security listed or traded on the New York Stock Exchange ("NYSE") or American Stock Exchange or other exchange is valued at its latest sale price prior to the time when assets are valued; if there were no sales that day, the security is valued at the mean between the last reported bid and ask price; (2) an equity portfolio security listed or traded on the Nasdaq is valued at the Nasdaq Official Closing Price; if there were no sales that day, the security is valued at the mean between the last reported bid and ask price; (3) all other portfolio securities for which over-the-counter market quotations are readily available are valu ed at the mean between the last reported bid and ask price. In cases where a security is traded on more than one exchange, the security is valued on the exchange designated as the primary market; (4) swaps are marked-to-market daily based upon quotations from market makers; (5) for equity securities traded on foreign exchanges, the last reported sale price or the latest bid price may be used if there were no sales on a particular day; (6) listed options are valued at the latest sale price on the exchange on which they are listed unless no sales of such options have taken place that day, in which case they are valued at the mean between their latest bid and ask price; (7) futures are valued at the latest price published by the commodities exchange on which they trade; (8) when market quotations are not readily available including circumstances under which Morgan Stanley Investment Advisors Inc. (the "Investment Adviser"), or Morgan Stanley Investment Management Limited or Morgan Stanley Investment Management Company (each, a "Sub-Adviser"), each a wholly owned subsidiary of Morgan Stanley, determines that the latest sale price, the bid price or the mean between the last reported bid and ask price do not reflect a security's market value, portfolio securities are

Morgan Stanley Variable Investment Series

Notes to Financial Statements n June 30, 2010 (unaudited) continued

valued at their fair value as determined in good faith under procedures established by and under the general supervision of the Fund's Trustees. Occasionally, developments affecting the closing prices of securities and other assets may occur between the times at which valuations of such securities are determined (that is, close of the foreign market on which the securities trade) and the close of business on the NYSE. If developments occur during such periods that are expected to materially affect the value of such securities, such valuations may be adjusted to reflect the estimated fair value of such securities as of the close of the NYSE, as determined in good faith by the Fund's Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Trustees of the Fund; (9) certain portfolio securities may be valued by an outside pricing service approved by the Fund's Trustees; (10) investments in ope n-end mutual funds, including the Morgan Stanley Institutional Liquidity Funds, are valued at the net asset value as of the close of each business day; and (11) short-term debt securities having a maturity date of more than sixty days at time of purchase are valued on a mark-to-market basis until sixty days prior to maturity and thereafter at amortized cost based on their value on the 61st day. Short-term debt securities having a maturity date of sixty days or less at the time of purchase are valued at amortized cost, which approximates market value.

B. Accounting for Investments — Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains and losses on security transactions are determined by the identified cost method. Dividend income and other distributions are recorded on the ex-dividend date except for certain dividends on foreign securities which are recorded as soon as the Fund is informed after the ex-dividend date. Interest income is accrued daily except where collection is not expected. Discounts are accreted and premiums are amortized over the life of the respective securities and are included in interest income. Interest income is accrued daily as earned.

C. Repurchase Agreements — The Fund may invest directly with institutions in repurchase agreements. The Fund's custodian receives the collateral, which is marked-to-market daily, to determine that the value of the collateral does not decrease below the repurchase price plus accrued interest as earned. If such a decrease occurs, additional collateral will be requested and, when received, will be added to the account to maintain full collateralization.

D. Multiple Class Allocations — Investment income, expenses (other than distribution fees), and realized and unrealized gains and losses are allocated to each class of shares based upon the relative net asset value on the date such items are recognized. Distribution fees are charged directly to the respective class.

E. Options — When the Fund writes a call or put option, an amount equal to the premium received is included in the Fund's Statement of Assets and Liabilities as a liability which is subsequently marked-to-market to reflect the current market value of the option written. If a written option either expires or the Fund enters into a

Morgan Stanley Variable Investment Series

Notes to Financial Statements n June 30, 2010 (unaudited) continued

closing purchase transaction, the Fund realizes a gain or loss without regard to any unrealized gain or loss on the underlying security or currency and the liability related to such option is extinguished. If a written call option is exercised, the Fund realizes a gain or loss from the sale of the underlying security or currency and the proceeds from such sale are increased by the premium originally received. If a written put option is exercised, the amount of the premium originally received reduces the cost of the security which the Fund purchases upon exercise of the option. By writing a covered call option, the Fund, in exchange for the premium, foregoes the opportunity for capital appreciation above the exercise price, should the market price of the underlying security increase. By writing a put option, the Fund, in exchange for the premium, accepts the risk of having to purchase a security at an exercise price that is above the current market price.

When the Fund purchases a call or put option, the premium paid is recorded as an investment which is subsequently marked-to-market to reflect the current market value. If a purchased option expires, the Fund will realize a loss to the extent of the premium paid. If the Fund enters into a closing sale transaction, a gain or loss is realized for the difference between the proceeds from the sale and the cost of the option. If a put option is exercised, the cost of the security or currency sold upon exercise will be increased by the premium originally paid. If a call option is exercised, the cost of the security purchased upon exercise will be increased by the premium originally paid. The maximum exposure to loss for any purchased option is limited to the premium initially paid for the option.

F. Futures — A futures contract is an agreement between two parties to buy and sell financial instruments or contracts based on financial indices at a set price on a future date. Upon entering into such a contract, the Fund is required to pledge to the broker: cash, U.S. Government securities or other liquid portfolio securities equal to the minimum initial margin requirements of the applicable futures exchange. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments known as variation margin are recorded by the Fund as unrealized gains and losses. Upon closing of the contract, the Fund realizes a 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.

G. Foreign Currency Translation and Forward Foreign Currency Contracts — The books and records of the Fund are maintained in U.S. dollars as follows: (1) the foreign currency market value of investment securities, other assets and liabilities and forward foreign currency contracts ("forward contracts") are translated at the exchange rates prevailing at the end of the period; and (2) purchases, sales, income and expenses are translated at the exchange rates prevailing on the respective dates of such transactions. The resultant exchange gains and losses are recorded as realized and unrealized gains/losses on

Morgan Stanley Variable Investment Series

Notes to Financial Statements n June 30, 2010 (unaudited) continued

forward contracts and foreign currency translations. Pursuant to U.S. federal income tax regulations, certain foreign exchange gains/losses included in realized and unrealized gains/losses are included in or are a reduction of ordinary income for federal income tax purposes. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in the market prices of the securities held. Forward contracts are valued daily at the appropriate exchange rates. The resultant unrealized exchange gains and losses are recorded as unrealized foreign currency translation gains or losses. The Fund records realized gains or losses on delivery of the currency or at the time the forward contract is extinguished (compensated) by entering into a closing transaction prior to delivery.

H. Securities Lending — The Fund may lend securities to qualified financial institutions, such as broker-dealers, to earn additional income. Any increase or decrease in the fair value of the securities loaned that might occur and any interest earned or dividends declared on those securities during the term of the loan would remain in the Fund. The Fund receives cash or securities as collateral in an amount equal to or exceeding 100% of the current fair value of the loaned securities. The collateral is marked-to-market daily, by the securities lending agent, to ensure that a minimum of 100% collateral coverage is maintained.

Based on pre-established guidelines, the securities lending agent invests any cash collateral that is received in high-quality short-term investments. Securities lending income is generated from the earnings on the invested collateral and borrowing fees, less any rebates owed to the borrowers and compensation to the lending agent.

PORTFOLIO				VALUE OF LOANED SECURITIES				VALUE OF COLLATERAL CASH⁽¹⁾
European Equity				$	1,493,425			$	1,617,062

⁽¹⁾ The Portfolio received cash collateral which was subsequently invested in Repurchase Agreements and Morgan Stanley Institutional Liquidity Funds as reported in the Portfolio of Investments.

The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

I. Swaps — Certain Portfolios may enter into credit default swap contracts, a type of credit derivative, for hedging purposes or to gain exposure to a credit or index of credits of underlying issue in which the Portfolio may otherwise invest. A credit default swap is an agreement between two parties to exchange the credit risk of an issuer or index of issuers. A buyer of a credit default swap is said to buy protection by paying periodic fees in return for a contingent payment from the seller if the issuer has a credit event such as bankruptcy, a failure to pay outstanding obligations or deteriorating credit while the swap is outstanding. A

100

Morgan Stanley Variable Investment Series

Notes to Financial Statements n June 30, 2010 (unaudited) continued

seller of a credit default swap is said to sell protection and thus collects the periodic fees and profits if the credit of the issuer remains stable or improves while the swap is outstanding. The seller in a credit default swap contract would be required to pay an agreed-upon amount, to the buyer in the event of an adverse credit event of the issuer. This agreed-upon amount approximates the notional amount of the swap as disclosed in the table following the Portfolio of Investments and is estimated to be the maximum potential future payment that the seller could be required to make under the credit default swap contract. In the event of an adverse credit event, the seller generally does not have any contractual remedies against the issuer or any other third party. However, if a physical settlement is elected, the seller would receive the defaulted credit and, as a result, become a creditor of the issuer.

The current credit rating of each individual issuer is listed in the table following the Portfolio of Investments and serves as indicator of the current status of the payment/performance risk of the credit derivative. Alternatively, for credit default swaps on an index of credits, the quoted market prices and current values serve as an indicator of the current status of the payment/performance risk of the credit derivative. Generally, lower credit ratings and increasing market values, in absolute terms, represent a deterioration of the credit and a greater likelihood of an adverse credit event of the issuer.

The Portfolios accrue for the periodic fees on credit default swaps on a daily basis as earned with the net amount accrued recorded within realized gains/losses on swap contracts on the Statement of Operations. Net unrealized gains are recorded as an asset or net unrealized losses are reported as a liability on the Statement of Assets and Liabilities. The change in value of the swap contracts is reported as unrealized gains or losses on the Statement of Operations. Payments received or made upon entering into a credit default swap contract, if any, are recorded as realized gains or losses on the Statement of Operations upon termination or maturity of the swap. Credit default swaps may involve greater risks than if a Portfolio had invested in the issuer directly. Credit default swaps are subject to general market risk, counterparty risk and credit risk.

Certain Portfolios may also enter into interest rate swaps and asset swaps (where parties combine the purchase or sale of a bond/note with an interest rate swap) primarily to preserve a return or spread on a particular investment or portion of its portfolio, as a duration management technique or to protect against any increase in the price of securities the Portfolio anticipates purchasing at a later date. These are contractual agreements to exchange periodic interest payment streams calculated on a predetermined notional principal amount. They generally involve one party paying a fixed interest rate and the other party paying a variable rate. The Portfolio will usually enter into them on a net basis, i.e, the two payment streams

101

Morgan Stanley Variable Investment Series

Notes to Financial Statements n June 30, 2010 (unaudited) continued

are netted out in a cash settlement on the payment date or date specified in the instrument, with the Portfolio receiving or paying, as the case may be, only the net amount of the two payments. The Portfolio accrues the net amount with respect to each swap on a daily basis. This net amount is recorded within realized gains/losses on swap contracts on the Statement of Operations. Risk may arise as a result of the potential inability of the counterparties to meet the terms of the contracts.

Swap agreements are not entered into or traded on exchanges and there is no central clearing or guaranty function for swaps. Therefore, swaps are subject to the risk of default or non-performance by the counterparty. If there is a default by the counterparty to a swap agreement, the Portfolio will have contractual remedies pursuant to the agreements related to the transaction. Counterparties are required to pledge collateral daily (based on the valuation of each swap) on behalf of the Portfolio with a value approximately equal to the amount of any unrealized gain. Reciprocally, when the Portfolio has an unrealized loss on a swap contract, the Portfolio has instructed the custodian to pledge cash or liquid securities as collateral with a value approximately equal to the amount of the unrealized loss. Collateral pledges are monitored and subsequently adjusted if and when the swap valuations fluctuate. For cash collateral received, the Portfolio pays a monthly fee to the counterparty based on the effective rate for Federal Funds.

J. Treasury Inflation-Protected Securities — Certain Portfolios may invest in Treasury Inflation-Protected Securities ("TIPS"), including structured bonds in which the principal amount is adjusted daily to keep pace with inflation, as measured by the U.S. Consumer Pricing Index for Urban Consumers. The adjustments to principal due to inflation/deflation are reflected as increases/decreases to interest income with a corresponding adjustment to cost. Such adjustments may have a significant impact on the Portfolio's distributions and may result in a return of capital to shareholders. The repayment of the original bond principal upon maturity is guaranteed by the full faith and credit of the U.S. Government.

K. Federal Income Tax Policy — It is the Fund's policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. The Fund files tax returns with the U.S. Internal Revenue Service, New York State and New York City. The Fund recognizes the tax effects of a tax position taken or expected to be taken in a tax return only if it is more likely than not to be sustained based solely on its technical merits as of the reporting date. The more-likely-than-not threshold must continue to be met in each reporting period to support continued recognition of the benefit. The difference between the tax benefit recognized in the financial statements for a tax position t aken and the tax

102

Morgan Stanley Variable Investment Series

Notes to Financial Statements n June 30, 2010 (unaudited) continued

benefit claimed in the income tax return is referred to as an unrecognized tax benefit. There are no unrecognized tax benefits in the accompanying financial statements. If applicable, the Fund recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in other expenses in the Statement of Operations. Each of the tax years filed in the four-year period ended December 31, 2009 remains subject to examination by taxing authorities.

L. Dividends and Distributions to Shareholders — The Fund records dividends and distributions to its shareholders on the ex-dividend date.

M. Expenses — Direct expenses are charged to the respective Portfolio and general Fund expenses are allocated on the basis of relative net assets or equally among the Portfolios.

N. Use of Estimates — The preparation of financial statements in accordance with generally accepted accounting principles in the United States ("GAAP") requires management to make estimates and assumptions that affect the reported amounts and disclosures. Actual results could differ from those estimates.

O. Subsequent Events — The Fund considers events or transactions that occur after the date of the Statement of Assets and Liabilities but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date of issuance of these financial statements.

P. Indemnifications — The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

2. Fair Valuation Measurements

Financial Accounting Standards Board Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures (ASC 820) (formerly known as FAS 157), defines fair value as the price that the Fund would receive to sell an investment or pay to transfer a liability in a timely transaction with an independent buyer in the principal market, or in the absence of a principal market, the most advantageous market for the investment or liability. ASC 820 establishes a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity's own assump tions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the

103

Morgan Stanley Variable Investment Series

circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Fund's investments. The inputs are summarized in the three broad levels listed below.

• Level 1 — unadjusted quoted prices in active markets for identical investments

• 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 Fund's own assumptions in determining the fair value of investments. Factors considered in making this determination may include, but are not limited to, information obtained by contacting the issuer, analysts, or the appropriate stock exchange (for exchange-traded securities), analysis of the issuer's financial statements or other available documents and, if necessary, available information concerning other securities in similar circumstances

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities and the determination of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to each security.

The following is a summary of the inputs used as of June 30, 2010 in valuing the Fund's investments carried at fair value:

Transfers between investment levels may occur as the markets fluctuate and/or the availability of data used in an investment's valuation changes. The Portfolios recognize transfers between the Levels as of the end of the period. As of June 30, 2010, securities transferred from Level 2 to Level 1. At December 31, 2009, the fair market value of certain securities were adjusted due to developments which occurred between the time of the close of the foreign markets on which they trade and the close of business on the NYSE which resulted in their Level 2 classification. The values of the transfers were as follows:

				Capital Opportunities				Aggressive Equity
				$	9,562,089			$	1,098,614

Following is a reconciliation of investments in which significant unobservable inputs (Level 3) were used in determining fair value:

3. Derivative Financial Instruments

A derivative financial instrument in very general terms refers to a security whose value is "derived" from the value of an underlying asset, reference rate or index.

The Fund may use derivative instruments for a variety of reasons, such as to attempt to protect the Fund against possible changes in the market value of its portfolio or to manage the Fund's foreign currency exposure or to generate potential gain. All of the Fund's portfolio holdings, including derivative instruments, are marked-to-market each day with the change in value reflected in unrealized

appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a contract. In these instances, the recognition of gain or loss is postponed until the disposal of the security underlying the contract. Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts.

Summarized below are specific types of derivative financial instruments used by certain Portfolios.

Forward Foreign Currency Contracts Certain Portfolios may enter into forward contracts for many purposes, including to facilitate settlement of foreign currency denominated portfolio transactions or to manage foreign currency exposure associated with foreign currency denominated securities. Forward contracts involve elements of market risk in excess of the amount reflected in the Statement of Assets and Liabilities. The respective Portfolios bear the risk of an unfavorable change in the foreign exchange rates underlying the forward contracts. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts.

During the six months ended June 30, 2010, the value of forward foreign currency contracts opened and closed were as follows:

PORTFOLIO	OPEN		CLOSE
Global Infrastructure	$	90,497,056	$	103,483,267
European Equity		28,263,081		33,076,310

Futures Certain Portfolios may purchase and sell interest rate, Eurodollar and index futures ("futures contracts") to facilitate trading, increase or decrease the Portfolio's market exposure, seek higher investment returns or to seek to protect against a decline in the value of the Portfolio's securities or an increase in prices of securities that may be purchased. These futures involve elements of market risk in excess of the amount reflected in the Statement of Assets and Liabilities. The respective Portfolios bear the risk of an unfavorable change in the value of the underlying securities. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts.

Options For hedging and investment purposes, certain Portfolios may engage in transactions in listed and over-the-counter options. Risks may arise from an imperfect correlation between the change in the market value of the securities held by the Portfolio and the price of options relating to the securities purchased or sold by the Portfolio and from the possible lack of a liquid secondary market for an option.

Swaps Certain Portfolios may enter into interest rate swaps and asset swaps (where parties combine the purchase or sale of a bond/note with an interest rate swap) and may purchase or sell interest rate caps, floors and collars. The Portfolio expects to enter into these transactions primarily to manage interest rate risk, hedge portfolio positions and preserve a return or spread on a particular investment or portion of its portfolio. The Portfolio may also enter into these transactions to protect against any increase in the price of securities the Portfolio anticipates purchasing at a later date. These transactions are subject to market risk, risk of default by the other party to the transaction, risk of imperfect correlation and manager risk. Such risks may exceed the related amounts shown in the Statement of Assets and Liabilities.

Certain Portfolios may enter into credit default swaps for hedging purposes, to add leverage to its portfolio or to gain exposure to a credit in which the Portfolio may otherwise invest. Credit default swaps may involve greater risks than if the Portfolio had invested in the issuer directly. Credit default swaps are subject to general market risk, counterparty risk and credit risk. If the Portfolio is a buyer and no credit event occurs, it will lose its investment. In addition, if the Portfolio is a seller and a credit event occurs, the value of the referenced obligation received by the Portfolio coupled with the periodic payments previously received may be less than the maximum payout amount it pays to the buyer, resulting in a loss to the Portfolio.

5. Plan of Distribution

Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the "Distributor"), an affiliate of the Investment Adviser, Administrator and Sub-Adviser. The Fund has adopted a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act. Under the Plan, Class Y shares of each Portfolio bear a distribution fee which is accrued daily and paid monthly at the annual rate of 0.25% of the average daily net assets of the class.

The Distributor, Investment Adviser and Administrator have voluntarily agreed to waive/reimburse all or a portion of the Money Market Portfolio's distribution fee, investment advisory fee and administration fee, respectively, to the extent that total expenses exceed total income of the Money Market Portfolio on a daily basis. For the six months ended June 30, 2010, the Distributor waived $95,065 and the Investment Adviser waived $276,503. The fee waivers and/or expense reimbursements are expected to continue until such time that the Board of Trustees acts to discontinue such waivers and/or reimbursements when it deems such action is appropriate.

Morgan Stanley Variable Investment Series

Notes to Financial Statements n June 30, 2010 (unaudited) continued

The Trustees voted to close the plan to new participants and eliminate the future benefits growth due to increases to compensation after July 31, 2003.

The Fund has an unfunded Deferred Compensation Plan (the "Compensation Plan") which allows each independent Trustee to defer payment of all, or a portion, of the fees he or she receives for serving on the Board of Trustees. Each eligible Trustee generally may elect to have the deferred amounts credited with a return equal to the total return on one or more of the Morgan Stanley funds that are offered as investment options under the Compensation Plan. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund.

7. Federal Income Tax Status

The amount of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations which may differ from GAAP. These "book/tax" differences are either considered temporary or permanent in nature. To the extent these

123

Morgan Stanley Variable Investment Series

Notes to Financial Statements n June 30, 2010 (unaudited) continued

differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences do not require reclassification. Dividends and distributions which exceed net investment income and net realized capital gains for tax purposes are reported as distributions of paid-in-capital.

As of December 31, 2009, the following Portfolios had a net capital loss carryforward which may be used to offset future capital gains to the extent provided by regulations.

permanent differences attributable to tax adjustment on swaps: Limited Duration, Income Plus and Strategist. The following Portfolios had temporary and permanent differences attributable to tax adjustments on passive foreign investment companies held/sold: Global Infrastructure and Strategist.

8. Purposes of and Risks Relating to Certain Financial Instruments

Certain Portfolios may lend securities to qualified financial institutions, such as broker-dealers, to earn additional income. Risks in securities lending transactions are that a borrower may not provide additional collateral when required or return the securities when due, and that the value of the short-term investments will be less than the amount of cash collateral plus any rebate that is required to be returned to the borrower.

Certain Portfolios may invest in mortgage securities, including securities issued by Federal National Mortgage Assoc. ("FNMA") and Federal Home Loan Mortgage Corp. ("FHLMC"). These are fixed income securities that derive their value from or represent interests in a pool of mortgages or mortgage securities. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of a mortgage backed security and could result in losses to the Portfolio. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. Subprime mortgages refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their mortgages. The securities held by the Portfolios are not backed by sub-prime mortgages.

Additionally, securities issued by FNMA and FHLMC are not backed by or entitled to the full faith and credit of the United States; rather, they are supported by the right of the issuer to borrow from the Treasury.

The Federal Housing Finance Agency ("FHFA") serves as conservator of FNMA and FHLMC and the U.S. Department of the Treasury has agreed to provide capital as needed to ensure FNMA and FHLMC continue to provide liquidity to the housing and mortgage markets.

At June 30, 2010, European Equity's investments in securities of issuers in the United Kingdom and Germany represented 44.6% and 16.9%, respectively of the Portfolio's net assets. These investments, as well as other non-U.S. investments, which involve risks and considerations not present with respect to U.S. securities, may be affected by economic or political developments in these countries.

9. New Accounting Pronouncement

On January 21, 2010, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2010-06. The ASU amends Accounting Standards Codification 820 to add new requirements for disclosures about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements. It also clarifies existing fair value disclosures

125

Morgan Stanley Variable Investment Series

Notes to Financial Statements n June 30, 2010 (unaudited) continued

about the level of disaggregation and about inputs and valuation techniques in Level 2 and Level 3 fair value measurements. The application of ASU 2010-06 is required for fiscal years and interim periods beginning after December 15, 2009, except for disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements, which are required for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years.
