The following replaces the section How Shares are Priced : How Shares are Priced Each Portfolio values its shares once each day only when the New York Stock Exchange (the Exchange ) is open for trading (typically Monday through Friday), as of the close of regular trading on the Exchange (normally 4:00 p.m. eastern time). If trading on the Exchange is halted for the day before the scheduled close of regular trading, a Portfolio s net asset value per share generally will still be calculated as of the scheduled close of regular trading on the Exchange. The purchase price of Portfolio shares is their net asset value (plus any applicable sales charge), which is derived from the value of Portfolio holdings. The Board of Directors has adopted procedures for valuing investments and has delegated to the Adviser the daily valuation of such investments. The Adviser has delegated daily valuation of each Portfolio except Calvert VP SRI Balanced Portfolio and Calvert VP SRI Mid Cap Portfolio to the applicable Sub-Adviser. Pursuant to the procedures, independent pricing services are used to value debt obligations at their market value. In determining market value, the pricing service considers various factors and market information. Exchange-listed securities and other instruments (including derivatives) normally are valued at last sale or closing prices. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers or pricing services. Such values may be based on valuation models, information provided by market makers or estimates of market values obtained from yield or market data relating to investments or securities with similar characteristics. In certain situations, the Adviser, or Sub-Adviser, if applicable, may use the fair value of a security if market prices are unavailable or deemed unreliable, or if events occur after the close of a securities market (usually a foreign market) and before portfolio assets are valued which would materially affect net asset value. In addition, for foreign equity securities and total return swaps and futures contracts on foreign indices that meet certain criteria, the Directors have approved the use of a fair value service that values such securities to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other instruments that have a strong correlation to the fair-valued securities. A security that is fair valued may be valued at a price higher or lower than actual market quotations or the value determined by other funds using their own fair valuation procedures. Because foreign securities trade on days when Portfolio shares are not priced, the value of securities held can change on days when Portfolio shares cannot be redeemed or purchased. The Adviser has established a Valuation Committee that oversees the valuation of investments. June 26, 2017 26522 6.26.17

Portfolio Summaries Calvert VP SRI Balanced Portfolio Investment Objective The Portfolio seeks to provide a competitive total return through an actively managed portfolio of stocks, bonds, and money market instruments which offer income and capital growth opportunity. Fees and Expenses of the Portfolio This table describes the fees and expenses that you may pay if you invest in shares of the Portfolio. The table and the following example do not reflect fees and charges imposed under the variable annuity contracts and life insurance policies (each a Policy ) through which an investment may be made. If those fees and charges were included, costs would be higher. Please consult the prospectus for your Policy for information regarding those fees and charges. (1) (2) Shareholder Fees (fees paid directly from your investment) Class I Class F Maximum sales charge (load) on purchases (as a% ofoffering price) None None Maximum deferred sales charge (load) (as a% ofamount purchased or redeemed, whichever is lower) None None Annual Fund Operating Expenses (expenses that you pay each year as a%ofthevalue of your investment) Class I Class F Management fees (1) 0.53% 0.53% Distribution and service (12b-1) fees None 0.25% Other expenses 0.17% 0.58% Total annual fund operating expenses 0.70% 1.36% Less fee waiver and/or expense reimbursement (2) 0.00% (0.26)% Total annual fund operating expenses after fee waiver and/or expense reimbursement 0.70% 1.10% Management fees are restated to reflect current contractual fees rather than the fees paid during the previous fiscal year. Calvert Research and Management ( CRM or the Adviser ) has agreed to reimburse the Portfolio s expenses to the extent that Total Annual Fund Operating Expenses exceed 1.10% for Class F shares. This expense reimbursement will continue through April 30, 2018. Any amendment to or termination of this reimbursement would require approval of the Board of Directors. The expense reimbursement relatestoordinaryoperatingexpensesonlyanddoesnotincludeexpensessuchasbrokeragecommissions, acquiredfundfeesandexpensesofunaffiliatedfunds, interestexpense, taxesorlitigationexpenses. Amounts reimbursed may be recouped by CRM during the same fiscal year to the extent actual expenses are less than the contractual expense cap during such year. Example. This example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The example assumes that: v you invest $10,000 in the Portfolio for the time periods indicated and then either redeem or hold your shares at the end of those periods; v your investment has a 5% return each year; v the Portfolio s operating expenses remain the same; and v any expense limitation is in effect for the period indicated in the fee table above. Although your actual costs may be higher or lower, under these assumptions your costs would be: Share Class 1 Year 3 Years 5 Years 10 Years Class I shares $72 $224 $390 $871 Class F shares $112 $405 $720 $1,612 Portfolio Turnover The Portfolio pays transaction costs, such as commissions, when it buys and sells securities ( turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Portfolio s performance. During the most recent fiscal year, the Portfolio s portfolio turnover rate was 129% of its portfolio s average value. Calvert Variable Products Portfolios 4

Principal Investment Strategies The Portfolio normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in companies and other issuers that the Adviser determines operate in a manner consistent with or promote The Calvert Principles for Responsible Investment (the Principles ). The Principles provide a framework for the Adviser s evaluation of investments considering environmental, social and governance factors. The Principles seek to identify companies and other issuers that operate in a manner that is consistent with or promote environmental sustainability and resource efficiency; equitable societies and respect for human rights; and accountable governance and transparency, among other factors. For additional information, please refer to Appendix A: The Calvert Principles for Responsible Investment. The Portfolio will provide shareholders with at least 60 days notice before changing this 80% policy. The Portfolio typically invests approximately 60% of its net assets in stocks and 40% in bonds or other fixed-income investments. Stock investments are primarily common stock in large-cap companies. Fixed-income investments are primarily a wide variety of investment grade debt securities, such as corporate debt securities, mortgage-backed securities (including commercial mortgage-backed securities and collateralized mortgage obligations ( CMOs )) and other asset-backed securities ( ABS ). The Portfolio invests in debt and mortgage-backed securities issued by government-sponsored enterprises ( GSEs ) such as the Federal National Mortgage Association ( FNMA ) and the Federal Home Loan Mortgage Corporation ( FHLMC ). The Portfolio may invest up to 25% of its net assets in publicly-traded real estate investment trusts ( REITs ). The Portfolio may invest up to 25% of its net assets in foreign securities, some of which may be issued by companies domiciled in emerging market countries. Foreign securities include, but are not limited to, securities that are issued by foreign governments, supranational entities and foreign corporations. As an alternative to holding foreign stocks directly, the Portfolio may invest in U.S. dollar-denominated securities of foreign companies that trade on U.S. exchanges or in the over-the-counter market (including American Depositary Receipts ( ADRs ) which may be sponsored or unsponsored and Global Depositary Receipts ( GDRs )). The Portfolio may invest in investment grade debt securities and below investment grade debt securities ( junk bonds ). The Portfolio may also invest in unrated debt securities. An investment grade debt security is rated BBB- or higher by Standard & Poor s Ratings Services ( S&P ) or by Fitch Ratings ( Fitch ), or Baa or higher by Moody s Investors Service, Inc. ( Moody s ), or is an unrated debt security determined by the Adviser to be of comparable credit quality. Below investment grade debt securities ( junk bonds ) are rated below BBB- by S&P or Fitch, or below Baa by Moody s, or is an unrated debt security determined by the Adviser to be of comparable credit quality. The Portfolio invests in a combination of stocks, bonds and money market instruments in an attempt to provide a complete investment portfolio in a single product. The Adviser monitors the Portfolio s allocation and may rebalance or reallocate the Portfolio s assets based on its view of economic and market factors and events. The equity portion of the Portfolio is primarily a large cap U.S. portfolio, although the Portfolio may also invest in foreign stocks and small- and mid-cap stocks. Stocks are selected primarily on the basis of fundamental research, utilizing the information provided by, and the expertise of, the Adviser s research staff and consideration of the responsible investing criteria described below. The portfolio managers may sell a security when they believe it is fully valued, the fundamentals of a company deteriorate, or to pursue alternative investment options. Investment decisions for the fixed-income portion of the Portfolio are made primarily on the basis of fundamental and quantitative research conducted by the Adviser s research staff and consideration of the responsible investing criteria described below. Management of the fixed-income portion of the Portfolio involves consideration of numerous factors (such as quality of business franchises, financial strength, management quality and security structural and collateral considerations). The portfolio managers may sell a security when the Adviser s price objective is reached, the fundamentals of the investment change or to pursue more attractive investment options. The Portfolio manages duration and any hedging of interest rate risk in the fixed-income portion of the Portfolio through the purchase and sale of U.S. Treasury securities and related futures contracts. The Portfolio does not have a specific target for its average portfolio duration and may invest in bonds and other fixed-income instruments of any maturity. Incidental to its main investment strategy, the Portfolio may also use futures contracts as a substitute for direct investment in a particular asset class, in order to facilitate the periodic rebalancing of the Portfolio to maintain its target asset allocation, to make tactical asset allocations and to assist in managing cash. Responsible Investing. In selecting investments for the Portfolio, CRM is guided by The Calvert Principles for Responsible Investment, which provide a framework for considering environmental, social and governance ( ESG ) factors that may affect investment performance. For additional information, please refer to Appendix A: The Calvert Principles for Responsible Investment. Principal Risks Management Risk. Individual investments of the Portfolio may not perform as expected, and the portfolio management practices may not achieve the desired result. There is a risk that the Adviser may allocate assets to an asset class that underperforms other asset classes. Calvert Variable Products Portfolios 5

Stock Market Risk. The market prices of stocks held by the Portfolio may fall. Common Stock Risk. Although common stocks have a history of long-term growth in value, their prices fluctuate based on changes in a company s financial condition, on overall market and economic conditions, and on investors perception of a company s well-being. Large-Cap Company Risk. Large-cap companies may be unable to respond quickly to new competitive challenges such as changes in technology, and also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion. Mid-Cap Company Risk. Prices of mid-cap stocks can be more volatile than those of larger, more established companies. Mid-cap companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. Small-Cap Company Risk. Prices of small-cap stocks can be more volatile than those of larger, more established companies. Small-cap companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. Foreign and Emerging Market Investment Risk. Because the Portfolio can invest a portion of its assets in foreign instruments, the value of shares may be adversely affected by changes in currency exchange rates and political, economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country. Investment markets in emerging market countries are typically smaller, less liquid and more volatile than developed markets, and emerging market securities often involve higher risk than developed market securities. Trading in foreign markets often involves higher expense than trading in the United States. The value of investments denominated in foreign currencies can be adversely affected by changes in foreign currency exchange rates. Depositary receipts are subject to many of the risks associated with investment directly in foreign instruments. Bond Market Risk. Economic and other events (whether real, expected or perceived) can reduce the demand for investments held by the Portfolio, which may reduce their market prices and cause the value of Portfolio shares to fall. The frequency and magnitude of such changes cannot be predicted. Certain securities and other investments held by the Portfolio can experience downturns in trading activity and, at such times, the supply of such instruments in the market may exceed the demand. At other times, the demand for such instruments may exceed the supply in the market. An imbalance in supply and demand in the market may result in greater price volatility, less liquidity, wider trading spreads and a lack of price transparency in the market. No active trading market may exist for certain investments, which may impair the ability of the Portfolio to sell or to realize the full value of such investments in the event of the need to liquidate such assets. Adverse market conditions may impair the liquidity of some actively traded investments. Fixed income markets have recently experienced a period of relatively high volatility due to rising U.S. treasury yields which, in part, reflect the market s expectations for higher U.S. economic growth and inflation. As a result of the Federal Reserve s recent decision to raise the target fed funds rate following a similar move last year and the possibility that it may continue with such rate increases and/or unwind its quantitative easing program, among other factors, markets could experience continuing high volatility, which could negatively impact the Portfolio s performance. Risk of Money Market Instruments. Money market instruments may be adversely affected by market and economic events, such as a sharp rise in prevailing short-term interest rates; adverse developments in the banking industry, which issues or guarantees many money market securities; adverse economic, political or other developments affecting domestic issuers of money market securities; changes in the credit quality of issuers and default by a counterparty. Interest Rate Risk. A change in interest rates may adversely affect the value of fixed-income securities. When interest rates rise, the value of fixed-income securities will generally fall. Longer-term securities are subject to greater interest rate risk. Credit Risk. The credit quality of fixed-income securities may deteriorate, which could lead to default or bankruptcy of the issuer where the issuer becomes unable to pay its obligations when due. Mortgage-Backed and Asset-Backed Securities Risk. The value of investments in mortgage-backed and asset-backed securities is subject to interest rate risk and credit risk. These securities are also subject to the risk that borrowers will prepay the principal on their loans more quickly than expected (prepayment risk) or more slowly than expected (extension risk), which will affect the yield, average life and price of the securities. In addition, faster-than-expected prepayments may cause the Portfolio to invest the prepaid principal in lower yielding securities and slower than expected prepayments may reduce the potential for the Portfolio to invest in higher yielding securities. Mortgage-Backed Security Risk (Government-Sponsored Enterprises). Debt and mortgage-backed securities issued by GSEs such as FNMA and FHLMC are neither insured nor guaranteed by the U.S. Treasury and are not backed by the full faith and credit of the U.S. government. Such securities are only supported by the credit of the applicable GSE. The U.S. government has provided financial support to FNMA and FHLMC, but there can be no assurance that it will support these or other GSEs in the future. Calvert Variable Products Portfolios 6

Collateralized Mortgage Obligation and Structured Asset-Backed Securities Risk. A CMO is a multiclass bond that is backed by a pool of mortgage loans or mortgage-backed securities. A structured ABS is a multiclass bond that is typically backed by a pool of auto loans, credit card receivables, home equity loans or student loans. A CMO or structured ABS is subject to interest rate risk, credit risk, prepayment risk and extension risk. In addition, if the Portfolio holds a class of a CMO or a structured ABS that is subordinated to other classes backed by the same pool of collateral, the likelihood that the Portfolio will receive payments of principal may be substantially limited. Below-Investment Grade Debt Securities Risk. Investments in below-investment grade debt securities (commonly known as junk bonds ) can involve a substantial risk of loss. Junk bonds are considered to be speculative with respect to the issuer s ability to pay interest and principal. These securities, which are rated below investment grade, have a higher risk of issuer default, are subject to greater price volatility than investment grade securities and may be illiquid. Unrated Security Risk. Unrated securities may be less liquid than rated securities determined to be of comparable quality by the Adviser. When the Portfolio purchases unrated securities it will depend on the Adviser s analysis of credit risk without the assessment of S&P, Moody s or Fitch. Real Estate Risks. Real estate investments, such as REITs, are subject to special risks including changes in real estate values, property taxes, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use, and rents, and the management skill and creditworthiness of the issuer. Changes in underlying real estate values may have an exaggerated effect to the extent that investments concentrate in particular geographic regions or property types. Active Trading Strategy Risk. The fixed-income portion of the Portfolio employs an active style that seeks to position the Portfolio with securities that offer the greatest price appreciation while minimizing risk. This style can result in higher turnover exceeding 100% and may translate to higher transaction costs. Futures Contracts Risk. The value of a futures contract tends to increase and decrease in tandem with the value of the underlying instrument. The price of futures can be highly volatile; using them could lower total return, and the potential loss from futures can exceed the Portfolio s initial investment in such contracts. Futures contracts may not provide an effective hedge of the underlying securities or indexes because changes in the prices of futures contracts may not track those of the securities or indexes that they are intended to hedge. Responsible Investing Risk. Investing primarily in responsible investments carries the risk that, under certain market conditions, the Portfolio may underperform funds that do not utilize a responsible investment strategy. The application of responsible investment criteria may affect the Portfolio s exposure to certain sectors or types of investments, and may impact the Portfolio s relative investment performance depending on whether such sectors or investments are in or out of favor in the market. An investment s ESG performance, or the Adviser s assessment of such performance, may change over time, which could cause the Portfolio to temporarily hold investments that do not comply with the Portfolio s responsible investment criteria. In evaluating an investment, the Adviser is dependent upon information and data that may be incomplete, inaccurate or unavailable, which could cause the Adviser to misanalyze the ESG factors relevant to a particular investment. Successful application of the Portfolio s responsible investment strategy will depend on the Adviser s skill in properly identifying and analyzing material ESG issues. General Portfolio Investing Risks. The Portfolio is not a complete investment program and there is no guarantee that the Portfolio will achieve its investment objective. It is possible to lose money by investing in the Portfolio. The Portfolio is designed to be a long-term investment vehicle and is not suited for short-term trading. Investors in the Portfolio should have a long-term investment perspective and be able to tolerate potentially sharp declines in value. An investment in the Portfolio is not a deposit in a bank and is not insured. Performance The following bar chart and table provide some indication of the risks of investing in the Portfolio by showing changes in the Portfolio s performance from year to year and how the Portfolio s average annual returns over time compare with a broad-based securities market index. The returns in the bar chart are for Class I shares. The Portfolio s past performance (before and after taxes) is not necessarily an indication of how the Portfolio will perform in the future. The Portfolio s performance reflects the effects of expense reductions. Absent these reductions, performance would have been lower. Effective December 31, 2016, Calvert Research and Management ( CRM ) is the investment adviser to the Portfolio and performance reflected prior to such date is that of the Portfolio s former investment adviser, Calvert Investment Management, Inc. The table below also shows the Balanced Composite benchmark because it is more consistent with the Portfolio s portfolio construction process and represents a more accurate reflection of the Portfolio s anticipated risk and return patterns. The returns shown do not reflect fees and charges imposed under the Policies through which an investment may be made. If those fees and charges were included, they would reduce these returns. Calvert Variable Products Portfolios 7

For the ten years ended December 31, 2016, the highest quarterly total return for Class I was 12.69% for the quarter ended September 30, 2009 and the lowest quarterly return was -19.57 % for the quarter ended December 31, 2008. Average Annual Total Returns as of December 31, 2016 One Year Five Years Ten Years Class I 7.42% 8.51% 4.55% Class F 7.39% 8.33% 4.46% Russell 1000 Index (reflects no deduction for fees or expenses) 12.05% 14.67% 7.08% Balanced Composite Benchmark (reflects no deduction for fees or expenses) 8.37% 10.14% 6.53% Performance results for Class F shares prior to October 18, 2013 (the Class F shares inception date) reflect the performance of Class I shares. Actual Class F share performance would have been lower than Class I share performance because Class F has higher class-specific expenses than Class I. The Balanced Composite Benchmark is an internally constructed benchmark comprised of a blend of 60% Russell 1000 Index and 40% Bloomberg Barclays U.S. Aggregate Bond Index, rebalanced monthly. Performance reported for periods prior to November 1, 2015 for the Balanced Composite Benchmark reflected the Bloomberg Barclays US Credit Index as the fixed income component. Investors cannot invest directly in an Index. Portfolio Management Investment Adviser. Effective December 31, 2016, Calvert Research and Management ( CRM or the Adviser ) is the investment adviser to the Portfolio. Portfolio Managers. Vishal Khanduja, CFA, Vice President of CRM, has managed the Portfolio since March 2013; Brian S. Ellis, CFA, Vice President of CRM, has managed the Portfolio since November 2015; Christopher Madden, CFA, Vice President of CRM, has managed the Portfolio since November 2015; Jade Huang, Vice President of CRM, has managed the Portfolio since November 2015; and Charles B. Gaffney, Vice President of CRM, has managed the Portfolio since December 31, 2016. Purchase and Redemption of Shares Shares of the Portfolio currently are sold only to participating insurance companies (the Insurance Companies ) for allocation to their separate accounts to fund benefits under Policies issued by the Insurance Companies. The Insurance Companies redeem shares of the Portfolio to make benefit and surrender payments under the terms of the Policies. Shares in the Portfolio are offered to the Insurance Companies, without sales charge, and redemptions are processed, on any day that the New York Stock Exchange is open. The share price is based on the Portfolio s net asset value, determined after an Insurance Company receives the premium payment or a surrender request in acceptable form. The Portfolio does not have minimum initial or subsequent investment requirements. A Policy owner s interest in the shares of the Portfolio is subject to the terms of the particular Policy described in the prospectus for that Policy. If you are considering purchasing a Policy, you should carefully review the prospectus for that Policy. Tax Information As a regulated investment company under the Internal Revenue Code, the Portfolio is not subject to federal income tax, or to federal excise tax, to the extent that it distributes its net investment income and realized capital gains to the separate accounts of the Insurance Companies. The Portfolio intends to distribute its net investment income and realized capital gains to the extent necessary to remain qualified as a regulated investment company. Since the only shareholders of the Portfolio are the Insurance Companies, no discussion is included here regarding the federal income tax consequences at the Policy owner level. For information on the federal tax consequences to you as a purchaser of a Policy, see the prospectus for your Policy. Calvert Variable Products Portfolios 8

Payments to Insurance Companies and their Affiliates The Portfolio is not sold directly to the general public but instead is offered as an underlying investment option for the Policies. The Portfolio and its related companies may make payments to a sponsoring Insurance Company (or its affiliates) for distribution and/or other services. These payments may be a factor that the Insurance Company considers in including the Portfolio as an underlying investment option in the Policy and may create a conflict of interest. The prospectus (or other offering document) for your Policy may contain additional information about these payments. Calvert Variable Products Portfolios 9

Calvert VP SRI Mid Cap Portfolio Investment Objective The Portfolio seeks to provide long-term capital appreciation by investing primarily in a portfolio of the equity securities of mid-sized companies that are undervalued but demonstrate a potential for growth. Fees and Expenses of the Portfolio This table describes the fees and expenses that you may pay if you invest in shares of the Portfolio. The table and the following example do not reflect fees and charges imposed under the variable annuity contracts and life insurance policies (each a Policy ) through which an investment may be made. If those fees and charges were included, costs would be higher. Please consult the prospectus for your Policy for information regarding those fees and charges. Shareholder Fees (fees paid directly from your investment) Maximum sales charge (load) on purchases (as a% ofoffering price) Maximum deferred sales charge (load) (as a% ofamount purchased or redeemed, whichever is lower) None None Annual Fund Operating Expenses (expenses that you pay each year as a%ofthevalue of your investment) Management fees (1) 0.77% Distribution and service (12b-1) fees None Other expenses 0.26% Total annual fund operating expenses 1.03% Less fee waiver and/or expense reimbursement (2) (0.04)% Total annual fund operating expenses after fee waiver and/or expense reimbursement 0.99% (1) (2) Management fees are restated to reflect current contractual fees rather than the fees paid during the previous fiscal year. Calvert Research and Management ( CRM or the Adviser ) has agreed to reimburse the Portfolio s expenses to the extent that Total Annual Fund Operating Expenses exceed 0.99% for Portfolio shares. This expense reimbursement will continue through April 30, 2018. Any amendment to or termination of this reimbursement would require approval of the Board of Directors. The expense reimbursement relatestoordinaryoperatingexpensesonlyanddoesnotincludeexpensessuchasbrokeragecommissions, acquiredfundfeesandexpensesofunaffiliatedfunds, interestexpense, taxesorlitigationexpenses. Amounts reimbursed may be recouped by CRM during the same fiscal year to the extent actual expenses are less than the contractual expense cap during such year. Example. This example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The example assumes that: v you invest $10,000 in the Portfolio for the time periods indicated and then either redeem or hold your shares at the end of those periods; v your investment has a 5% return each year; v the Portfolio s operating expenses remain the same; and v any expense limitation is in effect for the period indicated in the fee table above. Although your actual costs may be higher or lower, under these assumptions your costs would be: 1 Year 3 Years 5 Years 10 Years Portfolio Shares $101 $324 $565 $1,256 Portfolio Turnover The Portfolio pays transaction costs, such as commissions, when it buys and sells securities ( turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Portfolio s performance. During the most recent fiscal year, the Portfolio s portfolio turnover rate was 170% of its portfolio s average value. Principal Investment Strategies The Portfolio normally invests at least 80% of its net assets, (plus any borrowings for investment purposes) in the common stocks of mid-cap companies. The Portfolio will provide shareholders with at least 60 days notice before changing this 80% policy. The Portfolio defines mid-cap companies as those whose market capitalization falls within the range of the Russell Midcap Index at the time of investment. As of December 31, 2016, the market capitalization of the Russell Midcap Index companies ranged from $643 million to $57.6 billion with a weighted average level of $13.3 billion. Although primarily investing in mid-cap U.S. companies, Calvert Variable Products Portfolios 10

the Portfolio may also invest in small-cap companies. The Portfolio may invest up to 25% of its net assets in publicly-traded real estate investment trusts ( REITs ). The Portfolio normally will invest at least 80% of its net assets (plus any borrowings for investment purposes) in companies and other issuers that the Adviser determines operate in a manner consistent with or promote The Calvert Principles for Responsible Investment (the Principles ). The Principles provide a framework for the Adviser s evaluation of investments considering environmental, social and governance factors. The Principles seek to identify companies and other issuers that operate in a manner that is consistent with or promote: environmental sustainability and resource efficiency; equitable societies and respect for human rights; and accountable governance and transparency, among other factors. For additional information, please refer to Appendix A: The Calvert Principles for Responsible Investment. The Portfolio will provide shareholders with at least 60 days notice before changing this 80% policy. The Portfolio may invest up to 25% of its net assets in foreign securities, some of which may be issued by companies domiciled in emerging market countries. Foreign securities include, but are not limited to, securities that are issued by foreign governments, supranational entities and foreign corporations. As an alternative to holding foreign stocks directly, the Portfolio may invest in U.S. dollar-denominated securities of foreign companies that trade on U.S. exchanges or in the over-the-counter market (including American Depositary Receipts ( ADRs ), which may be sponsored or unsponsored, and Global Depositary Receipts ( GDRs )). The Adviser selects securities primarily on the basis of fundamental research, and consideration of the responsible investing criteria described below. The portfolio managers utilize the information provided by, and the expertise of, the Adviser s research staff in making investment decisions. In selecting securities, the portfolio managers seek companies that have sustainable earnings and cash flow, a strong and durable financial profile, secular and cyclical growth prospects, and the ability to maintain a competitive position within its industry. In addition, the portfolio managers employ a portfolio construction process that seeks to manage investment risk. This process includes the use of portfolio optimization tools (quantitative tools that help track the portfolio s fundamental characteristics such as its volatility, valuation and growth rate relative to the benchmark) and risk management techniques to assist in portfolio construction and monitoring and maintaining issuer and industry diversification among portfolio holdings. The portfolio managers may sell a security when they believe it is fully valued, the fundamentals of a company deteriorate, or to pursue alternative investment options. Responsible Investing. In selecting investments for the Portfolio, CRM is guided by The Calvert Principles for Responsible Investment, which provide a framework for considering environmental, social and governance ( ESG ) factors that may affect investment performance. For additional information, please refer to Appendix A: The Calvert Principles for Responsible Investment. Principal Risks Management Risk. Individual investments of the Portfolio may not perform as expected, and the portfolio management practices may not achieve the desired result. Stock Market Risk. The market prices of stocks held by the Portfolio may fall. Common Stock Risk. Although common stocks have a history of long-term growth in value, their prices fluctuate based on changes in a company s financial condition, on overall market and economic conditions, and on investors perception of a company s well-being. Mid-Cap Company Risk. Prices of mid-cap stocks can be more volatile than those of larger, more established companies. Mid-cap companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. Small-Cap Company Risk. Prices of small-cap stocks can be more volatile than those of larger, more established companies. Small-cap companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. Foreign and Emerging Market Investment Risk. Because the Portfolio can invest a portion of its assets in foreign instruments, the value of shares may be adversely affected by changes in currency exchange rates and political, economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country. Investment markets in emerging market countries are typically smaller, less liquid and more volatile than developed markets, and emerging market securities often involve higher risk than developed market securities. Trading in foreign markets often involves higher expense than trading in the United States. The value of investments denominated in foreign currencies can be adversely affected by changes in foreign currency exchange rates. Depositary receipts are subject to many of the risks associated with investment directly in foreign instruments. Real Estate Risks. Real estate investments, such as REITs, are subject to special risks, including changes in real estate values, property taxes, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use, and rents, and the management skill and creditworthiness of the issuer. Changes in underlying real estate values may have an exaggerated effect to the extent that investments concentrate in particular geographic regions or property types.

Responsible Investing Risk. Investing primarily in responsible investments carries the risk that, under certain market conditions, the Portfolio may underperform funds that do not utilize a responsible investment strategy. The application of responsible investment criteria may affect the Portfolio s exposure to certain sectors or types of investments, and may impact the Portfolio s relative investment performance depending on whether such sectors or investments are in or out of favor in the market. An investment s ESG performance, or the Adviser s assessment of such performance, may change over time, which could cause the Portfolio to temporarily hold investments that do not comply with the Portfolio s responsible investment criteria. In evaluating an investment, the Adviser is dependent upon information and data that may be incomplete, inaccurate or unavailable, which could cause the Adviser to misanalyze the ESG factors relevant to a particular investment. Successful application of the Portfolio s responsible investment strategy will depend on the Adviser s skill in properly identifying and analyzing material ESG issues. General Portfolio Investing Risks. The Portfolio is not a complete investment program and there is no guarantee that the Portfolio will achieve its investment objective. It is possible to lose money by investing in the Portfolio. The Portfolio is designed to be a long-term investment vehicle and is not suited for short-term trading. Investors in the Portfolio should have a long-term investment perspective and be able to tolerate potentially sharp declines in value. An investment in the Portfolio is not a deposit in a bank and is not insured. Performance The following bar chart and table provide some indication of the risks of investing in the Portfolio by showing changes in the Portfolio s performance from year to year and how the Portfolio s average annual returns over time compare with two broad-based securities market indexes. The Portfolio s past performance (before and after taxes) is not necessarily an indication of how the Portfolio will perform in the future. The Portfolio s performance reflects the effects of expense reductions. Absent these reductions, performance would have been lower. Effective December 31, 2016, Calvert Research and Management ( CRM ) is the investment adviser to the Portfolio and performance reflected prior to such date is that of the Portfolio s former investment adviser, Calvert Investment Management, Inc. The returns shown do not reflect fees and charges imposed under the Policies through which an investment may be made. If those fees and charges were included, they would reduce these returns. For the ten years ended December 31, 2016, the highest quarterly total return was 17.54% for the quarter ended December 31, 2010 and the lowest quarterly return was -25.51% for the quarter ended December 31, 2008. Average Annual Total Returns as of December 31, 2016 One Year Five Years Ten Years Portfolio Shares 7.24% 11.19% 7.64% Russell Midcap Index (reflects no deduction for fees or expenses) 13.80% 14.70% 7.85% Russell Midcap Growth Index (reflects no deduction for fees or expenses) 7.33% 13.49% 7.83% Effective June 6, 2016 the Portfolio s benchmark was changed to the Russell Midcap Index. The Midcap Index is more consistent with the Portfolio s composition and represents a more accurate reflection of the Portfolio s investment strategy. Investors cannot invest directly in an Index. Portfolio Management Investment Adviser. Effective December 31, 2016, Calvert Research and Management ( CRM or the Adviser ) is the investment adviser to the Portfolio. Portfolio Managers. Charles B. Gaffney, Vice President of CRM, has managed the Portfolio since December 31, 2016; Christopher Madden, CFA, Vice President of CRM, has managed the Portfolio since June 2016; and Jade Huang, Vice President of CRM, has managed the Portfolio since June 2016.

Purchase and Redemption of Shares Shares of the Portfolio currently are sold only to participating insurance companies (the Insurance Companies ) for allocation to their separate accounts to fund benefits under Policies issued by the Insurance Companies. The Insurance Companies redeem shares of the Portfolio to make benefit and surrender payments under the terms of the Policies. Shares in the Portfolio are offered to the Insurance Companies, without sales charge, and redemptions are processed, on any day that the New York Stock Exchange is open. The share price is based on the Portfolio s net asset value, determined after an Insurance Company receives the premium payment or a surrender request in acceptable form. The Portfolio does not have minimum initial or subsequent investment requirements. A Policy owner s interest in the shares of the Portfolio is subject to the terms of the particular Policy described in the prospectus for that Policy. If you are considering purchasing a Policy, you should carefully review the prospectus for that Policy. Tax Information As a regulated investment company under the Internal Revenue Code, the Portfolio is not subject to federal income tax, or to federal excise tax, to the extent that it distributes its net investment income and realized capital gains to the separate accounts of the Insurance Companies. The Portfolio intends to distribute its net investment income and realized capital gains to the extent necessary to remain qualified as a regulated investment company. Since the only shareholders of the Portfolio are the Insurance Companies, no discussion is included here regarding the federal income tax consequences at the Policy owner level. For information on the federal tax consequences to you as a purchaser of a Policy, see the prospectus for your Policy. Payments to Insurance Companies and their Affiliates The Portfolio is not sold directly to the general public but instead is offered as an underlying investment option for the Policies. The Portfolio and its related companies may make payments to a sponsoring Insurance Company (or its affiliates) for distribution and/or other services. These payments may be a factor that the Insurance Company considers in including the Portfolio as an underlying investment option in the Policy and may create a conflict of interest. The prospectus (or other offering document) for your Policy may contain additional information about these payments. Calvert Variable Products Portfolios 13
