Please refer to the fund's prospectus and Statement of Additional Information for additional details on the fund's risks. The order of the below risk factors does not indicate the significance of any particular risk factor.

The fund offers its shares only to separate accounts of insurance companies that offer variable annuity and variable life insurance products.

The fund's shares will change in value and you could lose money by investing in the fund. An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the fund's investment objective will be achieved.

Asset-backed securities are a type of debt security and are generally not backed by the full faith and credit of the U.S. government and are subject to the risk of default on the underlying asset or loan, particularly during periods of economic downturn.

During periods of falling interest rates if an issuer calls higher-yielding debt instruments, a fund may be forced to invest the proceeds at lower interest rates, likely resulting in a decline in the fund's income.

A convertible security is exposed to risks associated with both equity and debt securities. The value of convertibles may rise and fall with the market value of the underlying stock or vary with changes in interest rates and credit quality of the issuer.

An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due and the value of a security may decline as a result.

Ratings assigned by a credit rating agency are opinions of such entities, not absolute standards of credit quality and they do not evaluate risks of securities. Any shortcomings or inefficiencies in the process of determining credit ratings may adversely affect the credit ratings of the securities held by a fund and their perceived or actual credit risk.

Changes in currency exchange rates and the relative value of non-US currencies may affect the value of a fund's investments and the value of a fund's shares.

Current market conditions risk is the risk that a particular investment, or shares of the fund in general, may fall in value due to current market conditions. For example, changes in governmental fiscal and regulatory policies, disruptions to banking and real estate markets, actual and threatened international armed conflicts and hostilities, and public health crises, among other significant events, could have a material impact on the value of the fund's investments.

A fund is susceptible to operational risks through breaches in cyber security. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss.

Investments in debt securities subject the holder to the credit risk of the issuer and the value of debt securities will generally change inversely with changes in interest rates. In addition, debt securities generally do not trade on a securities exchange making them less liquid and more difficult to value.

Depositary receipts may be less liquid than the underlying shares in their primary trading market and distributions may be subject to a fee. Holders may have limited voting rights, and investment restrictions in certain countries may adversely impact their value.

Investments in emerging market securities are generally considered speculative and involve additional risks relating to political, economic and regulatory conditions.

Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.

A fund may invest in the shares of other ETFs, which involves additional expenses that would not be present in a direct investment in the underlying funds. In addition, a fund's investment performance and risks may be related to the investment performance and risks of the underlying funds.

Extension risk is the risk that, when interest rates rise, certain obligations will be paid off by the issuer (or other obligated party) more slowly than anticipated, causing the value of these debt securities to fall. Rising interest rates tend to extend the duration of debt securities, making their market value more sensitive to changes in interest rates.

Floating rate securities are structured so that the security's coupon rate fluctuates based upon the level of a reference rate. As a result, the coupon on floating rate securities will generally decline in a falling interest rate environment, causing a fund to experience a reduction in the income it receives from the security. A floating rate security's coupon rate resets periodically according to the terms of the security. Consequently, in a rising interest rate environment, floating rate securities with coupon rates that reset infrequently may lag behind the changes in market interest rates.

High yield securities, or "junk" bonds, are less liquid and are subject to greater market fluctuations and risk of loss than securities with higher ratings, and therefore, are considered to be highly speculative.

A fund's income may decline when interest rates fall or if there are defaults in its portfolio.

An index fund will be concentrated in an industry or a group of industries to the extent that the index is so concentrated. A fund with significant exposure to a single asset class, or the securities of issuers within the same country, state, region, industry, or sector may have its value more affected by an adverse economic, business or political development than a broadly diversified fund.

There is no assurance that the index provider or its agents will compile or maintain the index accurately. Losses or costs associated with any index provider errors generally will be borne by a fund and its shareholders.

A fund may own a significant portion of the First Trust ETFs included in a fund. Any such ETF may be removed from the Index if it does not comply with the Index's eligibility requirements. A fund may be forced to sell shares of certain First Trust ETFs at inopportune times or for prices other than at current market values or may elect not to sell such shares on the day that they are removed from the Index, due to market conditions or otherwise. Due to these factors, the variation between a fund's annual return and the return of the Index may increase significantly.

As inflation increases, the present value of a fund's assets and distributions may decline.

Interest rate risk is the risk that the value of the debt securities in a fund's portfolio will decline because of rising interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities.

Certain fund investments may be subject to restrictions on resale, trade over-the-counter or in limited volume, or lack an active trading market. Illiquid securities may trade at a discount and may be subject to wide fluctuations in market value.

Market risk is the risk that a particular security, or shares of a fund in general may fall in value. Securities are subject to market fluctuations caused by such factors as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious disease or other public health issues, recessions, natural disasters or other events could have significant negative impact on a fund.

A "momentum" style of investing emphasizes selecting stocks that have had higher recent price performance compared to other stocks. Momentum can turn quickly and cause significant variation from other types of investments.

Mortgage-related securities are more susceptible to adverse economic, political or regulatory events that affect the value of real estate.

The values of municipal securities may be adversely affected by local political and economic conditions and developments. Income from municipal securities could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of an issuer.

There are no government or agency guarantees of payments in securities offered by non- government issuers, therefore they are subject to the credit risk of the issuer. Non-agency securities often trade "over-the-counter" and there may be a limited market for them making them difficult to value.

An index fund's return may not match the return of the index for a number of reasons including operating expenses, costs of buying and selling securities to reflect changes in the index, and the fact that a fund's portfolio holdings may not exactly replicate the index.

Securities of non-U.S. issuers are subject to additional risks, including currency fluctuations, political risks, withholding, lack of liquidity, lack of adequate financial information, and exchange control restrictions impacting non-U.S. issuers.

A fund and a fund's advisor may seek to reduce various operational risks through controls and procedures, but it is not possible to completely protect against such risks. The fund also relies on third parties for a range of services, including custody, and any delay or failure related to those services may affect the fund's ability to meet its objective.

A fund that invests in securities included in or representative of an index will hold those securities regardless of investment merit and the fund generally will not take defensive positions in declining markets.

High portfolio turnover may result in higher levels of transaction costs and may generate greater tax liabilities for shareholders.

Prepayment risk is the risk that the issuer of a debt security will repay principal prior to the scheduled maturity date. Debt securities allowing prepayment may offer less potential for gains during a period of declining interest rates, as a fund may be required to reinvest the proceeds of any prepayment at lower interest rates.

A fund may be unable to sell a restricted security on short notice or only sell them at a price below current value.

Securities of small- and mid-capitalization companies may experience greater price volatility and be less liquid than larger, more established companies.

Investments in sovereign bonds involve special risks because the governmental authority that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due. In times of economic uncertainty, the prices of these securities may be more volatile than those of corporate debt or other government debt obligations.

Securities issued or guaranteed by federal agencies and U.S. government sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government.

A fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. Portfolio holdings that are valued using techniques other than market quotations, including "fair valued" assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. There is no assurance that a fund could sell or close out a portfolio position for the value established for it at any time.
