Investment Objective

The investment objective of the State Street Total Return V.I.S. Fund (the "Fund") is to seek the highest total return, composed of current income and capital appreciation, as is consistent with prudent investment risk.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund ("Fund Shares"), but does not reflect the fees or charges imposed by the separate accounts ("Accounts") of the life insurance companies through which shares of the Fund may be purchased. If these fees and charges were included, the costs shown below would be higher. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries which are not reflected in the tables and examples below. 

Shareholder Fees (fees paid directly from your investment) 

Maximum Sales Charge (Load) Imposed On Purchases (as a percentage of offering price)	None
Maximum Deferred Sales Charge (Load) (as a percentage of the lower of the sale proceeds or the original offering price)	None

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

Management Fees	0.35%
Distribution and/or Shareholder Service (12b-1) Fees	0.25%
Other Expenses (includes an Investor Service Plan fee of 0.20% of the average daily net assets)	0.25%
Acquired Fund Fees and Expenses1	0.07%
Total Annual Fund Operating Expenses	0.92%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example does not reflect the fees or charges imposed by the Accounts of the various life insurance companies through which shares of the Fund are offered. If these fees and charges were included, the expenses shown below would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 

      

1 year	3 years	5 years	10 years
$94	$293	$509	$1,131

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 77% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by constructing a broadly diversified portfolio that provides exposure to three primary asset classes either directly or indirectly through investment in exchange-traded funds ("ETFs"), including ETFs that pay fees to SSGA Funds Management, Inc. ("SSGA FM" or the "Adviser"), the Fund's investment adviser, and its affiliates for management, marketing or other services: (1) U.S. and foreign (non-U.S.) equity securities (the "Equity Class"); (2) U.S. and foreign (non-U.S.) debt securities (the "Fixed Income Class"); and (3) alternative-style investments (the "Alternative Class"). SSGA FM allocates the Fund's assets among the following sub-asset classes in proportions consistent with the potential returns and risks of each sub-asset class as well as the allocations that, in SSGA FM's view, will best meet the Fund's investment objective:

Under normal circumstances, the Fund anticipates maintaining an overall strategic target allocation range of 50%-70% of its assets in the Equity Class, 30%-50% of its assets in the Fixed Income Class, and 0%-5% of its assets in the Alternative Class. SSGA FM reviews these target allocations at least annually and may make changes over time when it believes it is beneficial to the Fund, including, but not limited to, adding or removing sub-asset classes or underlying ETFs, changing the sub-asset class target allocations, or maintaining the target allocations for longer or shorter periods of time. In addition, SSGA FM may from time to time make tactical adjustments to the Fund's allocation to a particular sub-asset class to pursue short to intermediate term opportunities based on a broad range of market and economic conditions, and a combination of quantitative and fundamental inputs. As a result of these tactical adjustments, the Fund's actual allocations may deviate from the overall strategic target allocations and, during certain periods, such deviations may be significant.

SSGA FM employs an "indexing" investment approach to assets allocated to the Equity, Fixed Income and Alternative Classes. SSGA FM divides the Classes into the sub-classes described above, and for each sub-class seeks to track the performance of an applicable market index. Under this investment approach, the Fund invests directly or through investment in ETFs either (1) in substantially all of the securities in an index in approximately the same proportion as the index (a "replication" strategy) or (2) in a representative sample of securities that collectively has an investment profile similar to an index (a "representative sampling" strategy). In a representative sampling strategy, the securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the index, and the Fund might or might not hold, directly or through investment in ETFs, all of the securities that comprise the index. For additional information regarding the investment process used to manage the Classes, including the sub-asset classes and applicable market indices, see the "More on the Underlying Investment Indices" section of this Prospectus.

      

SSGA FM may gain exposure to the various sub-asset classes by investing directly in individual securities or through investment in ETFs managed by SSGA FM or its affiliates as well as those managed by unaffiliated investment managers. The Fund (or the ETFs in which the Fund invests) may also use derivative instruments (including options, futures contracts, options on futures, interest rate swaps, credit default swaps, and forward contracts) to gain or hedge exposure to a certain type of security or broad-based index as an alternative to investing directly in or selling such type of security or the securities representing such index.

The Fund may hold cash or invest in money market instruments, principally for the preservation of capital, income potential or maintenance of liquidity.

Principal Risks

The Fund is subject to the following principal risks. You could lose money by investing in the Fund. The principal risks of investing in the Fund include risks from direct investments and/or indirect exposure through investment in the underlying funds. Certain risks relating to instruments and strategies used in the management of the Fund are placed first. The significance of any specific risk to an investment in the Fund will vary over time, depending on the composition of the Fund's portfolio, market conditions, and other factors. You should read all of the risk information presented below carefully, because any one or more of these risks may result in losses to the Fund. An investment in the Fund is subject to investment risks, including possible loss of principal, is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation ("FDIC") or any other government agency. The Fund may not achieve its investment objective. The Fund is not intended to be a complete investment program, but rather is intended for investment as part of a diversified investment portfolio. Investors should consult their own advisers as to the role of the Fund in their overall investment programs.

Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments.

Equity Investing Risk: The market prices of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer and also may decline due to general industry or market conditions that are not specifically related to a particular company. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options,

      

including investments in equity securities. High levels of inflation and/or a significantly changing interest rate environment can lead to heightened levels of volatility and reduced liquidity.

Indexing Strategy/Index Tracking Risk: The Fund is managed with an indexing investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of the Index or of the actual securities comprising the Index. This differs from an actively-managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund's performance may be less favorable than that of a portfolio managed using an active investment strategy. The structure and composition of the Index will affect the performance, volatility, and risk of the Index and, consequently, the performance, volatility, and risk of the Fund. While the Adviser seeks to track the performance of the Index (i.e., achieve a high degree of correlation with the Index), the Fund's return may not match the return of the Index. The Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities. In addition, the Fund may not be fully invested at times, generally as a result of cash flows into or out of the Fund or reserves of cash held by the Fund to meet redemptions. The Adviser may attempt to replicate the Index return by investing in fewer than all of the securities in the Index, or in some securities not included in the Index, potentially increasing the risk of divergence between the Fund's return and that of the Index.

Asset Allocation Risk: The Fund's investment performance depends upon the successful allocation by the Adviser of the Fund's assets among asset classes, geographical regions, industry sectors, and specific issuers and investments. There is no guarantee that the Adviser's allocation techniques and decisions will produce the desired results.

Below Investment-Grade Securities Risk: Lower-quality debt securities ("high yield" or "junk" bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general.

Commodities Risk: Commodity prices can have significant volatility, and exposure to commodities can cause the net asset value ("NAV") of Fund Shares to decline or fluctuate in a rapid and unpredictable manner. A liquid secondary market may not exist for certain commodity investments, which may make it difficult for the Fund to sell them at a desirable price or at the price at which it is carrying them.

Counterparty Risk: The Fund will be subject to credit risk with respect to the counterparties with which the Fund enters into derivatives contracts, repurchase agreements, reverse repurchase agreements, and other transactions. If a counterparty fails to meet its contractual obligations, the Fund may be unable to terminate or realize any gain on the investment or transaction, or to recover collateral posted to the counterparty, resulting in a loss to the Fund. If the Fund holds collateral posted by its counterparty, it may be delayed or prevented from realizing on the collateral in the event of a bankruptcy or insolvency proceeding relating to the counterparty.

Currency Risk: The value of the Fund's assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and delays, restrictions or prohibitions on the repatriation of foreign currencies. Foreign currency exchange rates may have significant volatility, and changes in the values of foreign currencies against the U.S. dollar may result in substantial declines in the values of the Fund's assets denominated in foreign currencies.

Currency Hedging Risk: If the Fund enters into currency hedging transactions, any loss generated by those transactions generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the hedging transaction and the risk sought to be hedged. There can be no assurance that the Fund's hedging transactions will be effective.

      

Derivatives Risk: Derivative transactions can create investment leverage and may have significant volatility. It is possible that a derivative transaction will result in a much greater loss than the principal amount invested, that changes in the value of a derivative transaction may not correlate perfectly with the underlying asset, and that the Fund may not be able to close out a derivative transaction at a favorable time or price. The counterparty to a derivatives contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations. A derivatives transaction may not behave in the manner anticipated by the Adviser or may not have the effect on the Fund anticipated by the Adviser.

Emerging Markets Risk: Risks of investing in emerging markets include, among others, greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, increased potential for market manipulation, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country's dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, less stringent investor protection and disclosure standards, less developed public health systems, and less developed legal systems. There is also the potential for unfavorable action such as expropriation, nationalization, embargoes, and acts of war. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries.

Exchange-Traded Funds Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by an underlying ETF in which it invests. In addition, the shares of an underlying ETF may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the NAV of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an underlying ETF or market disruptions may cause the market price of the underlying ETF to deviate from the value of the underlying ETF's investments, which may be exacerbated in less liquid markets.

Focused Investment Risk: To the extent the Fund invests a large percentage of its assets in securities within the same country, state, region, or economic sector its investment strategy could result in more risk or greater volatility in returns than if the Fund's investments were less focused.

Inflation-Indexed Securities Risk: The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Adviser.

Large-Capitalization Securities Risk: Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies. Larger companies may be unable to respond as quickly as smaller and mid-sized companies to competitive challenges or to changes in business, product, financial, or other market conditions. Larger companies may not be able to maintain growth at the high rates that may be achieved by well-managed smaller and mid-sized companies.

Large Transactions Risk: To the extent a large proportion of the shares of the Fund are held by a small number of shareholders (or a single shareholder), including funds or accounts over which the Adviser has investment discretion, the Fund is subject to the risk that these shareholders will purchase or redeem Fund Shares in large amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser. In addition, a large number of shareholders collectively may purchase or redeem Fund Shares in large amounts rapidly or unexpectedly (collectively, such transactions are referred to as "large shareholder transactions"). Large shareholder transactions could adversely affect the ability of the Fund to conduct its investment program.

      

Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector.

Management Risk: The Fund is actively managed. The Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy or as to a hedging strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results.

Modeling Risk: The Adviser uses quantitative models in an effort to enhance returns and manage risk. Any imperfections, errors or limitations in these models could limit any benefit to the Fund from the use of the models, or could result in incorrect outputs or in investment outcomes different from or opposite to those expected or desired by the Adviser. There can be no assurance that the models will behave as expected in all market conditions. In addition, computer programming used to create quantitative models, or the data on which such models operate, might contain one or more errors.

Mortgage-Related and Other Asset-Backed Securities Risk: Investments in mortgage-related and other asset-backed securities are subject to the risk of significant credit downgrades, illiquidity, and defaults to a greater extent than many other types of fixed-income investments. The liquidity of mortgage-related and asset-backed securities may change over time. During periods of falling interest rates, mortgage- and asset-backed securities may be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of mortgage- and asset-backed securities may extend, which may lock in a below-market interest rate, increase the security's duration and interest rate sensitivity, and reduce the value of the security. Enforcing rights against the underlying assets or collateral may be difficult, and the underlying assets or collateral may be insufficient if the issuer defaults.

Non-U.S. Securities Risk: Non-U.S. securities (including depositary receipts) are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent that the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Investments in depositary receipts may be less liquid and more volatile than the underlying shares in their primary trading market.

Portfolio Turnover Risk: Frequent purchases and sales of portfolio securities may result in higher Fund expenses.

REIT Risk: REITs are subject to the risks associated with investing in the securities of real property companies. In particular, REITs may be affected by changes in the values of the underlying properties that they own or operate. Further, REITs are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency and, as a result, are particularly reliant on the proper functioning of capital markets. A variety of economic and other factors may adversely affect a lessee's ability to meet its obligations to a REIT. In the event

      

of a default by a lessee, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments. In addition, a REIT could fail to qualify for favorable regulatory treatment.

Risk of Investment in Other Pools: When the Fund invests in another pooled investment vehicle (e.g., a mutual fund or exchange-traded fund), it is exposed to the risk that the other pool will not perform as expected and is exposed indirectly to all of the risks applicable to an investment in such other pool. The investment policies of the other pool may not be the same as those of the Fund; as a result, an investment in the other pool may be subject to additional or different risks than those to which the Fund is typically subject. The Fund bears its proportionate share of the fees and expenses of any pool in which it invests. The Adviser or an affiliate may serve as investment adviser to a pool in which the Fund may invest, leading to potential conflicts of interest. It is possible that other clients of the Adviser or its affiliates will purchase or sell interests in a pool sponsored or managed by the Adviser or its affiliates at prices and at times more favorable than those at which the Fund does so.

Small-, Mid-, and Micro-Capitalization Securities Risk: The securities of small-, mid- and micro-capitalization companies may be more volatile and may involve more risk than the securities of larger companies. These companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, and may depend on a few key employees. In addition, these companies may have been recently organized and may have little or no track record of success. The securities of smaller companies may trade less frequently and in smaller volumes than more widely held securities. Some securities of smaller issuers may be illiquid or may be restricted as to resale, and their values may have significant volatility. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. Returns on investments in securities of small-, mid- and micro-capitalization companies could trail the returns on investments in securities of larger companies.

Sovereign Debt Obligations Risk: Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt.

U.S. Government Securities Risk: Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation ("Freddie Mac") and the Federal National Mortgage Association ("Fannie Mae") may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks.

Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including "fair valued" securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Investors who purchase or redeem Fund Shares on days when the Fund is holding fair-valued investments may receive fewer

      

Performance

The bar chart and table below provide some indication of the risks of investing in the Fund by illustrating the variability of the Fund's returns from year-to-year and by showing how the Fund's average annual returns for the periods indicated compared with that of three broad measures of market performance. The bar chart shows the performance of the Fund's Class 3 Shares. On August 1, 2018, the Fund changed to its current principal investment strategies. If the Fund's current principal investment strategies had been in place for these prior periods, performance information shown may have been different. The bar chart and average annual total returns table do not reflect the fees or charges imposed by the Accounts of the life insurance companies through which shares of the Fund may be purchased. If these fees and charges were included, returns would be lower than those shown. The Fund's past performance does not necessarily indicate how the Fund will perform in the future. Current performance information for the Fund is available toll free by calling (800)-242-0134 or by visiting our website at www.ssga.com.

Purchase and Sale of Fund Shares

The Fund does not offer its shares to the general public. Shares of the Fund are currently offered only to Accounts of various life insurance companies as funding vehicles for certain variable contracts issued by such life insurance companies.

State Street Variable Insurance Series Funds, Inc. (the "Company") has entered into an agreement with the life insurance company sponsor of each Account (the "participation agreement") setting forth the terms and conditions pursuant to which the insurance company will purchase and redeem shares of the Fund. For information regarding the purchase and sale of Fund Shares, see your insurance contract prospectus (the "contract prospectus") or other disclosure document for such insurance contract which describes the particular Account and variable contract.

Tax Information

Since the Accounts of the various life insurance companies are the only shareholders of the Fund, no discussion is included herein as to the U.S. federal income tax consequences for such Accounts. For information concerning the U.S. federal income tax consequences to the purchasers of variable contracts, see the contract prospectus or other disclosure document for such contract which describes the particular Account and variable contract.

Payments To Insurance Companies, Broker-Dealers And Other Financial Intermediaries

Shares of the Fund are available only through the purchase of variable contracts issued by certain life insurance companies. The Company and its affiliates may pay such insurance companies (or their related companies) for the sale of shares of the Fund and/or administrative or other related services. When received by an insurance company, such payments may be a factor that the insurance company considers in including the Fund as an investment option in its variable contracts. The prospectus or other disclosure document for the variable contracts may contain additional information about these payments. Such insurance companies (or their related companies) may pay broker-dealers or other financial intermediaries (such as banks) that sell the variable contracts for the sale of shares of the Fund and related services. When received by a broker-dealer or other intermediary, such payments may create a conflict of interest by influencing the broker-dealer or other intermediary and salespersons to recommend the Fund over other mutual funds available as investment options in a variable contract. Ask the salesperson or visit the financial intermediary's website for more information.
