Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The Fund is offered exclusively as an investment option for certain Contracts. The table below reflects only Fund expenses and does not reflect Contract fees and expenses. If Contract fees and expenses were included, the fees and expenses in the following table would be higher. Please refer to the Contract prospectus for a description of those fees and expenses.

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. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and that you reinvest all dividends and distributions. It does not reflect any Contract fees. If Contract fees were included, the costs shown would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 12% of the average value of its portfolio.

 Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund is a fund of funds that, under normal market conditions, seeks to achieve its investment objective by investing primarily in a combination of five underlying index funds:

The AZL Enhanced Bond Index Fund is a bond index fund, subadvised by BlackRock Financial Management, Inc.; the other four underlying funds are equity index funds, subadvised by BlackRock Investment Management, LLC. Under normal market conditions, the Fund will allocate approximately 50% of its assets in the underlying equity index funds and approximately 50% of its assets in the underlying bond index fund. These target allocations represent the Fund’s long-term strategic asset allocation, which is not expected to change under normal market conditions.

Allocation Risk – The Manager’s decisions regarding how the Fund’s assets should be allocated among the various underlying funds, may cause the Fund to underperform other funds with similar investment objectives. There can be no guarantee that investment decisions made by the Manager will produce the desired results. Further, because the Manager has limited discretion to change the underlying fund allocations under normal market conditions, the Fund may underperform comparable funds of funds for which the fund’s manager has such discretion to adjust allocations to underlying funds.

Fund of Funds Risk – The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further, due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

Market Risk – The market value of portfolio securities may go up or down, sometimes rapidly and unpredictably. The value of a security or other asset may fluctuate significantly due to factors such as changes in general market conditions, including economic, political, and financial conditions, widespread disease or other public health issues, war, military conflict, acts of terrorism, adverse investor sentiment, or instability or other disruptive events in the local, regional or global markets. Certain changes in the U.S. economy, such as a decrease in imports or exports, changes in trade regulations, inflation and/or economic recession, may have an adverse effect on the value of the Fund’s securities.

Issuer Risk – The value of a security may decline for a number of reasons directly related to the issuer of the security. Further, the value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Index Fund Risk – Certain of the underlying funds do not attempt to manage market volatility or reduce the effects of poor performance. In addition, factors such as fund expenses, selection of a representative portfolio, changes in the composition of the index, or the timing of purchases or redemptions of fund shares may affect the correlation between the performance of the index and the fund’s performance.

Selection Risk – Because the AZL Enhanced Bond Index Fund is actively managed, there can be no guarantee that investment decisions made for the Fund will produce the desired results.

Capitalization Risk – Investing in small- to mid-sized companies creates risk because smaller companies may have unpredictable or limited earnings, and their securities may be less liquid or experience more volatile prices than those of large companies.

Foreign Securities Risk – Investing in the securities of non-U.S. issuers involves a number of risks, such as fluctuations in currency values, adverse political, social or economic developments, and differences in social and economic developments or policies.

Risks of Investing in Japan – Japan may be subject to political, economic, nuclear, and labor risks, among others. Any of these risks, individually or in the aggregate, can impact an investment made in Japan. Since 2000, Japan’s economic growth rate has generally remained low relative to other advanced economies, and it may remain low in the future. The Japanese economy faces several concerns, any of which could negatively affect the value of Japanese investments. In addition, Japan’s labor market is adapting to an aging workforce, declining population, and demand for increased labor mobility. These demographic shifts and fundamental structural changes to the labor market may negatively impact Japan’s economic competitiveness.

European Investment Risk – Investments in certain countries in the European Union (the “EU”) are susceptible to high political, social, or economic risks due to restrictions on inflation rates, rising debt levels and fiscal and monetary controls. Efforts of the member countries to further unify their economic and monetary policies may increase the potential for the downward movement of one member country’s market to cause a similar effect on other member countries’ markets. Separately, the EU faces issues involving its membership, structure, procedures and policies. The exit of one or more member countries from the EU, such as the exit of the United Kingdom (known as “Brexit”), could place its currency and banking system in jeopardy. An exit by other member countries could likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which may adversely affect a fund’s investments.

Financials Sector Risk – The performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades, decreased liquidity in credit markets and adverse conditions in other related markets. Companies in the financials sector may also hold portfolios of assets concentrated in geographic markets, industries or products (such as commercial and residential real estate loans) which makes them especially vulnerable to unstable economic conditions. The extent to which a fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. The impact of changes in capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. Cyberattacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact a fund.

When-Issued, Delayed Delivery Securities and Forward Commitments Risk – The purchase or sale of securities on a when issued basis or on a delayed delivery basis or through a forward commitment involves the purchase or sale of securities at an established price with payment and delivery taking place in the future. When-issued and delayed delivery transactions subject a fund to market risk because the value or yield of a security at delivery may be more or less than the purchase price or yield generally available when delivery occurs, and counterparty risk because the fund relies on the buyer or seller, as the case may be, to consummate the transaction. These transactions also have a leveraging effect on a fund because the fund commits to purchase securities that it does not have to pay for until a later date, which increases the fund’s overall investment exposure and, as a result, its volatility.

Emerging Markets Risk – Emerging markets may have less developed or more volatile trading markets and greater likelihood of government restrictions, nationalization, or confiscation than developed countries. Companies in emerging market countries may have less developed legal and accounting systems and generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable which can impede a fund’s ability to evaluate such companies. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. In addition, investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Currency Risk – Investing in securities that trade in and receive revenues in foreign currencies creates risk because foreign currencies may decline relative to the U.S. dollar, resulting in a potential loss to a fund. In the case of hedging positions, the U.S. dollar may decline in value relative to the currency that has been hedged.

Sovereign Debt Risk – Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

Treasury Obligations Risk – Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of a fund. Because U.S. Treasury obligations trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. In addition, changes in the credit rating or financial condition of the U.S. government may cause the value of U.S. Treasury Obligations to decline. Although a fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the fund.

U.S. Government Obligations Risk – Certain securities in which a fund may invest, including securities issued by certain government agencies and government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Financial Markets Regulatory Risk – Policy changes by the U.S. government or its regulatory agencies and other governmental actions and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact a fund, including by adversely impacting the fund’s operations, universe of potential investment options, and return potential.

Interest Rate Risk – Debt securities held by a fund may decline in value due to rising interest rates. Macroeconomic factors, such as inflationary trends, can heighten interest rate risk.

Credit Risk – The failure of the issuer of a debt security to pay interest or repay principal in a timely manner may have an adverse impact on a fund’s earnings.

Income Risk – Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. Falling interest rates may cause a fund’s income to decline.

Call Risk – If interest rates fall, issuers of callable debt securities are more likely to prepay prior to the maturity date. A fund may not be able to reinvest the proceeds from the prepayment in investments that will generate the same level of income.

Extension Risk – If interest rates rise, debt securities may be paid in full more slowly than anticipated. Periods of low relative interest rates or inflationary trends may increase the risks associated with rising interest rates.

Derivatives Risk – Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. Derivatives are subject to a number of other risks, such as liquidity risk, interest rate risk, market risk, credit risk, counterparty risk, and selection risk. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value may not correlate perfectly with the underlying asset, rate, or index. Using derivatives may result in losses, possibly in excess of the principal amount invested.

Futures Risk – The value of futures contracts depend primarily upon the price of the securities, indexes, commodities, currencies or other instruments underlying them. Price movements are also influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary, and exchange control programs and policies of governments, and national and international political and economic events and policies. The cost of futures may also be related, in part, to the degree of volatility of the underlying indices, securities, currencies, or other assets. Accordingly, futures on highly volatile indices, securities, currency, or other assets may be more expensive than futures on other investments. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.

Swaps Risk – A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Leveraging Risk – Certain underlying funds may engage in certain kinds of transactions, including the use of derivatives, that may give rise to a form of leverage. The use of leverage may require a fund to liquidate a portfolio position at a disadvantageous time or may exaggerate the effect of any increase or decrease in the value of a fund’s portfolio securities.

Liquidity Risk – An investment that is difficult to purchase or sell may have an adverse effect on the fund’s returns. Liquid securities can become illiquid during periods of market stress. If a significant amount of the fund’s securities become illiquid, the fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Mortgage-Related and Other Asset-Backed Securities Risk – Investing in mortgage-related or other asset-backed securities involves a variety of risks associated with the credit markets, such as rising or falling interest rates, increases in the rate of defaults or prepayments, and the quality of the pool of mortgages (subprime risk) or other assets that back the security.

Portfolio Turnover Risk – Certain underlying funds may trade portfolio securities frequently, which could result in higher transaction costs and could adversely affect the fund’s performance.

Privately Placed, Rule 144A and Other Exempt Securities Risk – Certain underlying funds may invest in privately placed securities, which are subject to resale restrictions. The market for Rule 144A and other securities exempt from certain registration requirements may be less active than the market for publicly-traded securities. Rule 144A and other exempt securities carry the risk that their liquidity may become impaired and a fund may be unable to dispose of the securities at a desirable time or price.

Repurchase Agreements and Purchase and Sale Contracts Risk – If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, a fund may suffer delays and incur costs or lose

Information Technology Sector Risk – Information technology companies may have limited product lines, markets, financial resources or personnel. Information technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

Collateralized Debt Obligations Risk – In addition to the typical risks associated with fixed-income securities and asset-backed securities, collateralized debt obligations, including CLOs, carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) a fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment return achieved by a fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) the risk of forced “fire sale” liquidation due to technical defaults such as coverage test failures; and (viii) the CDO’s manager may perform poorly.

Non-Diversification Risk – To the extent an underlying fund becomes non-diversified, the underlying fund may invest a larger percentage of its assets in securities issued by or representing a small number of issuers than can a diversified fund. As a result, the underlying fund’s shares may experience greater price volatility and the underlying fund may be more susceptible to the risks associated with these particular issuers or to a single economic, political or regulatory occurrence affecting these issuers, which may negatively impact the underlying fund’s performance.

The following bar chart and table provide an indication of the risks of an investment in the Fund by showing changes in its performance from year to year and by showing how the Fund’s average annual returns for one year, five years and ten years compare with those of a broad-based measure of market performance, the S&P 500 Index. The Fund’s performance also is compared to the Bloomberg U.S. Aggregate Bond Index, which shows how the Fund’s performance compares with the returns of a broad index of investment-grade fixed-rate debt issues, and to the Balanced Composite Index, which shows how the Fund’s performance compares with a composite index composed of the S&P 500 Index (50%) and the Bloomberg U.S. Aggregate Bond Index (50%) in proportions similar to the equity to fixed income allocation of the Fund.

Both the bar chart and the table assume reinvestment of dividends and distributions.

The performance of the Fund will vary from year to year. The Fund’s performance does not reflect the cost of insurance and separate account charges which are imposed under your Contract. If they were included, performance would be reduced. Past performance does not indicate how the Fund will perform in the future.

 Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund is a fund of funds that, under normal market conditions, seeks to achieve its investment objective by investing approximately 95% of its assets in a combination of five underlying index funds:

In addition, under normal market conditions, the Fund will allocate approximately 5% of its assets to the MVP risk management process, described below.

The AZL Enhanced Bond Index Fund is a bond index fund, subadvised by BlackRock Financial Management, Inc.; the other four underlying funds are equity index funds, subadvised by BlackRock Investment Management, LLC. Under normal market conditions, the Fund will allocate approximately 50% of its underlying fund assets in the underlying equity

Allocation Risk – The Manager’s decisions regarding how the Fund’s assets should be allocated among the various underlying funds, may cause the Fund to underperform other funds with similar investment objectives. There can be no guarantee that investment decisions made by the Manager will produce the desired results. Further, because the Manager has limited discretion to change the underlying fund allocations under normal market conditions, the Fund may underperform comparable funds of funds for which the fund’s manager has such discretion to adjust allocations to underlying funds.

Futures Risk – Because the Fund may utilize futures pursuant to its MVP risk management process, the Fund also is subject to derivatives risk, including risks related to futures. Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. The value of futures contracts depend primarily upon the price of the securities, indexes, commodities, currencies or other instruments underlying them. Price movements are also influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary, and exchange control programs and policies of governments, and national and international political and economic events and policies. The cost of futures may also be related, in part, to the degree of volatility of the underlying indices, securities, currencies, or other assets. Accordingly, futures on highly volatile indices, securities, currency, or other assets may be more expensive than futures on other investments. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.

Volatility Risk – Although the Fund’s investment strategy seeks not to exceed a specific volatility level, certain of the Fund’s investments may appreciate or decrease significantly in value over short periods of time, which may cause the Fund’s net asset value per share to experience significant increases or declines in value over short periods of time. The Fund’s volatility strategy may not produce the desired result and there can be no guarantee that the Fund will maintain volatility at or below its threshold volatility level. Additionally, maintenance of the volatility level will not ensure that the Fund will deliver competitive returns. The use of derivatives in connection with the Fund’s volatility strategy may expose the Fund to losses (some of which may be sudden) that it would not have otherwise been exposed to if it had only invested directly in equity and/or fixed income securities. Further, in some market conditions the Fund may either underperform or outperform as a direct result of the MVP process. The Fund may, for example, outperform in downward trending markets when volatility is high (and the equity allocation low) and underperform in upward trending markets when volatility is high (and the equity allocation low).

Quantitative Investing Risk – The value of securities selected using quantitative analysis can react differently to issuer, political, market, and economic developments than the market as a whole or securities selected using only fundamental analysis. The factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value. In addition, factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model. A quantitative model can be adversely affected by errors or imperfections in the factors or the data on which evaluations are based, or by technical issues with construction or implementation of the model, which in any case may result in a failure of the portfolio to perform as expected or a failure to identify securities that will perform well in the future. Successful operation of a quantitative model is also reliant upon the information technology systems of the Manager or Subadviser, as applicable, and its ability to ensure those systems remain operational and that appropriate

Fund of Funds Risk – The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further, due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any futures and cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

In addition, the Fund bears the investment risks of the investments of the underlying funds. The principal risks associated with the underlying funds include:

Market Risk – The market value of portfolio securities may go up or down, sometimes rapidly and unpredictably. The value of a security or other asset may fluctuate significantly due to factors such as changes in general market conditions, including economic, political, and financial conditions, widespread disease or other public health issues, war, military conflict, acts of terrorism, adverse investor sentiment, or instability or other disruptive events in the local, regional or global markets. Certain changes in the U.S. economy, such as a decrease in imports or exports, changes in trade regulations, inflation and/or economic recession, may have an adverse effect on the value of the Fund’s securities.

Issuer Risk – The value of a security may decline for a number of reasons directly related to the issuer of the security. Further, the value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Index Fund Risk – Certain of the underlying funds do not attempt to manage market volatility or reduce the effects of poor performance. In addition, factors such as fund expenses, selection of a representative portfolio, changes in the composition of the index, or the timing of purchases or redemptions of fund shares may affect the correlation between the performance of the index and the fund’s performance.

Selection Risk – Because the AZL Enhanced Bond Index Fund is actively managed, there can be no guarantee that investment decisions made for the Fund will produce the desired results.

Capitalization Risk – Investing in small- to mid-sized companies creates risk because smaller companies may have unpredictable or limited earnings, and their securities may be less liquid or experience more volatile prices than those of large companies.

Foreign Securities Risk – Investing in the securities of non-U.S. issuers involves a number of risks, such as fluctuations in currency values, adverse political, social or economic developments, and differences in social and economic developments or policies.

Risks of Investing in Japan – Japan may be subject to political, economic, nuclear, and labor risks, among others. Any of these risks, individually or in the aggregate, can impact an investment made in Japan. Since 2000, Japan’s economic growth rate has generally remained low relative to other advanced economies, and it may remain low in the future. The Japanese economy faces several concerns, any of which could negatively affect the value of Japanese investments. In addition, Japan’s labor market is adapting to an aging workforce, declining population, and demand for increased labor mobility. These demographic shifts and fundamental structural changes to the labor market may negatively impact Japan’s economic competitiveness.

European Investment Risk – Investments in certain countries in the European Union (the “EU”) are susceptible to high political, social, or economic risks due to restrictions on inflation rates, rising debt levels and fiscal and monetary controls. Efforts of the member countries to further unify their economic and monetary policies may increase the potential for the downward movement of one member country’s market to cause a similar effect on other member countries’ markets. Separately, the EU faces issues involving its membership, structure, procedures and policies. The exit of one or more member countries from the EU, such as the exit of the United Kingdom (known as “Brexit”), could place its currency and banking system in jeopardy. An exit by other member countries could likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which may adversely affect a fund’s investments.

Financials Sector Risk – The performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades, decreased liquidity in

When-Issued, Delayed Delivery Securities and Forward Commitments Risk – The purchase or sale of securities on a when issued basis or on a delayed delivery basis or through a forward commitment involves the purchase or sale of securities at an established price with payment and delivery taking place in the future. When-issued and delayed delivery transactions subject a fund to market risk because the value or yield of a security at delivery may be more or less than the purchase price or yield generally available when delivery occurs, and counterparty risk because the fund relies on the buyer or seller, as the case may be, to consummate the transaction. These transactions also have a leveraging effect on a fund because the fund commits to purchase securities that it does not have to pay for until a later date, which increases the fund’s overall investment exposure and, as a result, its volatility.

Emerging Markets Risk – Emerging markets may have less developed or more volatile trading markets and greater likelihood of government restrictions, nationalization, or confiscation than developed countries. Companies in emerging market countries may have less developed legal and accounting systems and generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable which can impede a fund’s ability to evaluate such companies. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. In addition, investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Currency Risk – Investing in securities that trade in and receive revenues in foreign currencies creates risk because foreign currencies may decline relative to the U.S. dollar, resulting in a potential loss to a fund. In the case of hedging positions, the U.S. dollar may decline in value relative to the currency that has been hedged.

Sovereign Debt Risk – Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

Treasury Obligations Risk – Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of a fund. Because U.S. Treasury obligations trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. In addition, changes in the credit rating or financial condition of the U.S. government may cause the value of U.S. Treasury Obligations to decline. Although a fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the fund.

U.S. Government Obligations Risk – Certain securities in which a fund may invest, including securities issued by certain government agencies and government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Financial Markets Regulatory Risk – Policy changes by the U.S. government or its regulatory agencies and other governmental actions and political events within the U.S. and abroad may, among other things, affect investor and

Interest Rate Risk – Debt securities held by a fund may decline in value due to rising interest rates. Macroeconomic factors, such as inflationary trends, can heighten interest rate risk.

Credit Risk – The failure of the issuer of a debt security to pay interest or repay principal in a timely manner may have an adverse impact on a fund’s earnings.

Income Risk – Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. Falling interest rates may cause a fund’s income to decline.

Call Risk – If interest rates fall, issuers of callable debt securities are more likely to prepay prior to the maturity date. A fund may not be able to reinvest the proceeds from the prepayment in investments that will generate the same level of income.

Extension Risk – If interest rates rise, debt securities may be paid in full more slowly than anticipated. Periods of low relative interest rates or inflationary trends may increase the risks associated with rising interest rates.

Derivatives Risk – Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. Derivatives are subject to a number of other risks, such as liquidity risk, interest rate risk, market risk, credit risk, counterparty risk, and selection risk. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value may not correlate perfectly with the underlying asset, rate, or index. Using derivatives may result in losses, possibly in excess of the principal amount invested.

Swaps Risk – A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Leveraging Risk – Certain underlying funds may engage in certain kinds of transactions, including the use of derivatives, that may give rise to a form of leverage. The use of leverage may require a fund to liquidate a portfolio position at a disadvantageous time or may exaggerate the effect of any increase or decrease in the value of a fund’s portfolio securities.

Liquidity Risk – An investment that is difficult to purchase or sell may have an adverse effect on the fund’s returns. Liquid securities can become illiquid during periods of market stress. If a significant amount of the fund’s securities become illiquid, the fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Mortgage-Related and Other Asset-Backed Securities Risk – Investing in mortgage-related or other asset-backed securities involves a variety of risks associated with the credit markets, such as rising or falling interest rates, increases in the rate of defaults or prepayments, and the quality of the pool of mortgages (subprime risk) or other assets that back the security.

Portfolio Turnover Risk – Certain underlying funds may trade portfolio securities frequently, which could result in higher transaction costs and could adversely affect the fund’s performance.

Privately Placed, Rule 144A and Other Exempt Securities Risk – Certain underlying funds may invest in privately placed securities, which are subject to resale restrictions. The market for Rule 144A and other securities exempt from certain registration requirements may be less active than the market for publicly-traded securities. Rule 144A and other exempt securities carry the risk that their liquidity may become impaired and a fund may be unable to dispose of the securities at a desirable time or price.

Repurchase Agreements and Purchase and Sale Contracts Risk – If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, a fund may suffer delays and incur costs or lose

Information Technology Sector Risk – Information technology companies may have limited product lines, markets, financial resources or personnel. Information technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

Collateralized Debt Obligations Risk – In addition to the typical risks associated with fixed-income securities and asset-backed securities, collateralized debt obligations, including CLOs, carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) a fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment return achieved by a fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) the risk of forced “fire sale” liquidation due to technical defaults such as coverage test failures; and (viii) the CDO’s manager may perform poorly.

Non-Diversification Risk – To the extent an underlying fund becomes non-diversified, the underlying fund may invest a larger percentage of its assets in securities issued by or representing a small number of issuers than can a diversified fund. As a result, the underlying fund’s shares may experience greater price volatility and the underlying fund may be more susceptible to the risks associated with these particular issuers or to a single economic, political or regulatory occurrence affecting these issuers, which may negatively impact the underlying fund’s performance.

The following bar chart and table provide an indication of the risks of an investment in the Fund by showing changes in its performance from year to year and by showing how the Fund’s average annual returns for one year, five years and ten years compare with those of a broad-based measure of market performance, the S&P 500 Index. The Fund’s performance also is compared to the Bloomberg U.S. Aggregate Bond Index, which shows how the Fund’s performance compares with the returns of a broad index of investment-grade fixed-rate debt issues, and to the Balanced Composite Index, which shows how the Fund’s performance compares with a composite index composed of the S&P 500 Index (50%) and the Bloomberg U.S. Aggregate Bond Index (50%) in proportions similar to the equity to fixed income allocation of the Fund.

Both the bar chart and the table assume reinvestment of dividends and distributions.

The performance of the Fund will vary from year to year. The Fund’s performance does not reflect the cost of insurance and separate account charges which are imposed under your Contract. If they were included, performance would be reduced. Past performance does not indicate how the Fund will perform in the future.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The Fund is offered exclusively as an investment option for certain Contracts. The table below reflects only Fund expenses and does not reflect Contract fees and expenses. If Contract fees and expenses were included, the fees and expenses in the following table would be higher. Please refer to the Contract prospectus for a description of those fees and expenses.

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. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and that you reinvest all dividends and distributions. It does not reflect any Contract fees. If Contract fees were included, the costs shown would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 12% of the average value of its portfolio.

 Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund is a fund of funds that, under normal market conditions, seeks to achieve its investment objective by investing approximately 95% of its assets in a combination of five underlying index funds:

In addition, under normal market conditions, the Fund will allocate approximately 5% of its assets to the MVP risk management process, described below.

The AZL Enhanced Bond Index Fund is a bond index fund, subadvised by BlackRock Financial Management, Inc.; the other four underlying funds are equity index funds, subadvised by BlackRock Investment Management, LLC. Under normal market conditions, the Fund will allocate approximately 75% of its underlying fund assets in the underlying equity

Allocation Risk – The Manager’s decisions regarding how the Fund’s assets should be allocated among the various underlying funds, may cause the Fund to underperform other funds with similar investment objectives. There can be no guarantee that investment decisions made by the Manager will produce the desired results. Further, because the Manager has limited discretion to change the underlying fund allocations under normal market conditions, the Fund may underperform comparable funds of funds for which the fund’s manager has such discretion to adjust allocations to underlying funds.

Futures Risk – Because the Fund may utilize futures pursuant to its MVP risk management process, the Fund also is subject to derivatives risk, including risks related to futures. Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. The value of futures contracts depend primarily upon the price of the securities, indexes, commodities, currencies or other instruments underlying them. Price movements are also influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary, and exchange control programs and policies of governments, and national and international political and economic events and policies. The cost of futures may also be related, in part, to the degree of volatility of the underlying indices, securities, currencies, or other assets. Accordingly, futures on highly volatile indices, securities, currency, or other assets may be more expensive than futures on other investments. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.

Volatility Risk – Although the Fund’s investment strategy seeks not to exceed a specific volatility level, certain of the Fund’s investments may appreciate or decrease significantly in value over short periods of time, which may cause the Fund’s net asset value per share to experience significant increases or declines in value over short periods of time. The Fund’s volatility strategy may not produce the desired result and there can be no guarantee that the Fund will maintain volatility at or below its threshold volatility level. Additionally, maintenance of the volatility level will not ensure that the Fund will deliver competitive returns. The use of derivatives in connection with the Fund’s volatility strategy may expose the Fund to losses (some of which may be sudden) that it would not have otherwise been exposed to if it had only invested directly in equity and/or fixed income securities. Further, in some market conditions the Fund may either underperform or outperform as a direct result of the MVP process. The Fund may, for example, outperform in downward trending markets when volatility is high (and the equity allocation low) and underperform in upward trending markets when volatility is high (and the equity allocation low).

Quantitative Investing Risk – The value of securities selected using quantitative analysis can react differently to issuer, political, market, and economic developments than the market as a whole or securities selected using only fundamental analysis. The factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value. In addition, factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model. A quantitative model can be adversely affected by errors or imperfections in the factors or the data on which evaluations are based, or by technical issues with construction or implementation of the model, which in any case may result in a failure of the portfolio to perform as expected or a failure to identify securities that will perform well in the future. Successful operation of a quantitative model is also reliant upon the information technology systems of the Manager or Subadviser, as applicable, and its ability to ensure those systems remain operational and that appropriate

Fund of Funds Risk – The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further, due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any futures and cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

In addition, the Fund bears the investment risks of the investments of the underlying funds. The principal risks associated with the underlying funds include:

Market Risk – The market value of portfolio securities may go up or down, sometimes rapidly and unpredictably. The value of a security or other asset may fluctuate significantly due to factors such as changes in general market conditions, including economic, political, and financial conditions, widespread disease or other public health issues, war, military conflict, acts of terrorism, adverse investor sentiment, or instability or other disruptive events in the local, regional or global markets. Certain changes in the U.S. economy, such as a decrease in imports or exports, changes in trade regulations, inflation and/or economic recession, may have an adverse effect on the value of the Fund’s securities.

Issuer Risk – The value of a security may decline for a number of reasons directly related to the issuer of the security. Further, the value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Index Fund Risk – Certain of the underlying funds do not attempt to manage market volatility or reduce the effects of poor performance. In addition, factors such as fund expenses, selection of a representative portfolio, changes in the composition of the index, or the timing of purchases or redemptions of fund shares may affect the correlation between the performance of the index and the fund’s performance.

Selection Risk – Because the AZL Enhanced Bond Index Fund is actively managed, there can be no guarantee that investment decisions made for the Fund will produce the desired results.

Capitalization Risk – Investing in small- to mid-sized companies creates risk because smaller companies may have unpredictable or limited earnings, and their securities may be less liquid or experience more volatile prices than those of large companies.

Foreign Securities Risk – Investing in the securities of non-U.S. issuers involves a number of risks, such as fluctuations in currency values, adverse political, social or economic developments, and differences in social and economic developments or policies.

Risks of Investing in Japan – Japan may be subject to political, economic, nuclear, and labor risks, among others. Any of these risks, individually or in the aggregate, can impact an investment made in Japan. Since 2000, Japan’s economic growth rate has generally remained low relative to other advanced economies, and it may remain low in the future. The Japanese economy faces several concerns, any of which could negatively affect the value of Japanese investments. In addition, Japan’s labor market is adapting to an aging workforce, declining population, and demand for increased labor mobility. These demographic shifts and fundamental structural changes to the labor market may negatively impact Japan’s economic competitiveness.

European Investment Risk – Investments in certain countries in the European Union (the “EU”) are susceptible to high political, social, or economic risks due to restrictions on inflation rates, rising debt levels and fiscal and monetary controls. Efforts of the member countries to further unify their economic and monetary policies may increase the potential for the downward movement of one member country’s market to cause a similar effect on other member countries’ markets. Separately, the EU faces issues involving its membership, structure, procedures and policies. The exit of one or more member countries from the EU, such as the exit of the United Kingdom (known as “Brexit”), could place its currency and banking system in jeopardy. An exit by other member countries could likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which may adversely affect a fund’s investments.

Financials Sector Risk – The performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades, decreased liquidity in

When-Issued, Delayed Delivery Securities and Forward Commitments Risk – The purchase or sale of securities on a when issued basis or on a delayed delivery basis or through a forward commitment involves the purchase or sale of securities at an established price with payment and delivery taking place in the future. When-issued and delayed delivery transactions subject a fund to market risk because the value or yield of a security at delivery may be more or less than the purchase price or yield generally available when delivery occurs, and counterparty risk because the fund relies on the buyer or seller, as the case may be, to consummate the transaction. These transactions also have a leveraging effect on a fund because the fund commits to purchase securities that it does not have to pay for until a later date, which increases the fund’s overall investment exposure and, as a result, its volatility.

Emerging Markets Risk – Emerging markets may have less developed or more volatile trading markets and greater likelihood of government restrictions, nationalization, or confiscation than developed countries. Companies in emerging market countries may have less developed legal and accounting systems and generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable which can impede a fund’s ability to evaluate such companies. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. In addition, investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Currency Risk – Investing in securities that trade in and receive revenues in foreign currencies creates risk because foreign currencies may decline relative to the U.S. dollar, resulting in a potential loss to a fund. In the case of hedging positions, the U.S. dollar may decline in value relative to the currency that has been hedged.

Sovereign Debt Risk – Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

Treasury Obligations Risk – Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of a fund. Because U.S. Treasury obligations trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. In addition, changes in the credit rating or financial condition of the U.S. government may cause the value of U.S. Treasury Obligations to decline. Although a fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the fund.

U.S. Government Obligations Risk – Certain securities in which a fund may invest, including securities issued by certain government agencies and government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Financial Markets Regulatory Risk – Policy changes by the U.S. government or its regulatory agencies and other governmental actions and political events within the U.S. and abroad may, among other things, affect investor and

Interest Rate Risk – Debt securities held by a fund may decline in value due to rising interest rates. Macroeconomic factors, such as inflationary trends, can heighten interest rate risk.

Credit Risk – The failure of the issuer of a debt security to pay interest or repay principal in a timely manner may have an adverse impact on a fund’s earnings.

Income Risk – Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. Falling interest rates may cause a fund’s income to decline.

Call Risk – If interest rates fall, issuers of callable debt securities are more likely to prepay prior to the maturity date. A fund may not be able to reinvest the proceeds from the prepayment in investments that will generate the same level of income.

Extension Risk – If interest rates rise, debt securities may be paid in full more slowly than anticipated. Periods of low relative interest rates or inflationary trends may increase the risks associated with rising interest rates.

Derivatives Risk – Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. Derivatives are subject to a number of other risks, such as liquidity risk, interest rate risk, market risk, credit risk, counterparty risk, and selection risk. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value may not correlate perfectly with the underlying asset, rate, or index. Using derivatives may result in losses, possibly in excess of the principal amount invested.

Swaps Risk – A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Leveraging Risk – Certain underlying funds may engage in certain kinds of transactions, including the use of derivatives, that may give rise to a form of leverage. The use of leverage may require a fund to liquidate a portfolio position at a disadvantageous time or may exaggerate the effect of any increase or decrease in the value of a fund’s portfolio securities.

Liquidity Risk – An investment that is difficult to purchase or sell may have an adverse effect on the fund’s returns. Liquid securities can become illiquid during periods of market stress. If a significant amount of the fund’s securities become illiquid, the fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Mortgage-Related and Other Asset-Backed Securities Risk – Investing in mortgage-related or other asset-backed securities involves a variety of risks associated with the credit markets, such as rising or falling interest rates, increases in the rate of defaults or prepayments, and the quality of the pool of mortgages (subprime risk) or other assets that back the security.

Portfolio Turnover Risk – Certain underlying funds may trade portfolio securities frequently, which could result in higher transaction costs and could adversely affect the fund’s performance.

Privately Placed, Rule 144A and Other Exempt Securities Risk – Certain underlying funds may invest in privately placed securities, which are subject to resale restrictions. The market for Rule 144A and other securities exempt from certain registration requirements may be less active than the market for publicly-traded securities. Rule 144A and other exempt securities carry the risk that their liquidity may become impaired and a fund may be unable to dispose of the securities at a desirable time or price.

Repurchase Agreements and Purchase and Sale Contracts Risk – If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, a fund may suffer delays and incur costs or lose

Information Technology Sector Risk – Information technology companies may have limited product lines, markets, financial resources or personnel. Information technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

Collateralized Debt Obligations Risk – In addition to the typical risks associated with fixed-income securities and asset-backed securities, collateralized debt obligations, including CLOs, carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) a fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment return achieved by a fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) the risk of forced “fire sale” liquidation due to technical defaults such as coverage test failures; and (viii) the CDO’s manager may perform poorly.

Non-Diversification Risk – To the extent an underlying fund becomes non-diversified, the underlying fund may invest a larger percentage of its assets in securities issued by or representing a small number of issuers than can a diversified fund. As a result, the underlying fund’s shares may experience greater price volatility and the underlying fund may be more susceptible to the risks associated with these particular issuers or to a single economic, political or regulatory occurrence affecting these issuers, which may negatively impact the underlying fund’s performance.

The following bar chart and table provide an indication of the risks of an investment in the Fund by showing changes in its performance from year to year and by showing how the Fund’s average annual returns for one year, five years and ten years compare with those of a broad-based measure of market performance, the S&P 500 Index. The Fund’s performance also is compared to the Bloomberg U.S. Aggregate Bond Index, which shows how the Fund’s performance compares with the returns of a broad index of investment-grade fixed-rate debt issues, and to the Growth Composite Index, which shows how the Fund’s performance compares with a composite index composed of the S&P 500 Index (75%) and the Bloomberg U.S. Aggregate Bond Index (25%) in proportions similar to the equity to fixed income allocation of the Fund.

The factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value. In addition, factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model.

Fund of Funds Risk – The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further, due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any futures and cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

Certain changes in the U.S. economy, such as a decrease in imports or exports, changes in trade regulations, inflation and/or economic recession, may have an adverse effect on the value of the Fund’s securities.

Issuer Risk – The value of a security may decline for a number of reasons directly related to the issuer of the security. Further, the value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Index Fund Risk – Certain of the underlying funds do not attempt to manage market volatility or reduce the effects of poor performance. In addition, factors such as fund expenses, selection of a representative portfolio, changes in the composition of the index, or the timing of purchases or redemptions of fund shares may affect the correlation between the performance of the index and the fund’s performance.

Risks of Investing in Japan – Japan may be subject to political, economic, nuclear, and labor risks, among others. Any of these risks, individually or in the aggregate, can impact an investment made in Japan. Since 2000, Japan’s economic growth rate has generally remained low relative to other advanced economies, and it may remain low in the future. The Japanese economy faces several concerns, any of which could negatively affect the value of Japanese investments. In addition, Japan’s labor market is adapting to an aging workforce, declining population, and demand for increased labor mobility. These demographic shifts and fundamental structural changes to the labor market may negatively impact Japan’s economic competitiveness.

European Investment Risk – Investments in certain countries in the European Union (the “EU”) are susceptible to high political, social, or economic risks due to restrictions on inflation rates, rising debt levels and fiscal and monetary controls. Efforts of the member countries to further unify their economic and monetary policies may increase the potential for the downward movement of one member country’s market to cause a similar effect on other member countries’ markets. Separately, the EU faces issues involving its membership, structure, procedures and policies. The exit of one or more member countries from the EU, such as the exit of the United Kingdom (known as “Brexit”), could place its currency and banking system in jeopardy. An exit by other member countries could likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which may adversely affect a fund’s investments.

Financials Sector Risk – The performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades, decreased liquidity in credit markets and adverse conditions in other related markets. Companies in the financials sector may also hold portfolios of assets concentrated in geographic markets, industries or products (such as commercial and residential real estate loans) which makes them especially vulnerable to unstable economic conditions. The extent to which a fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. The impact of changes in capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. Cyberattacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact a fund.

When-Issued, Delayed Delivery Securities and Forward Commitments Risk – The purchase or sale of securities on a when issued basis or on a delayed delivery basis or through a forward commitment involves the purchase or sale of securities at an established price with payment and delivery taking place in the future. When-issued and delayed delivery transactions subject a fund to market risk because the value or yield of a security at delivery may be more or less than the purchase price or yield generally available when delivery occurs, and counterparty risk because the fund relies on the buyer or seller, as the case may be, to consummate the transaction. These transactions also have a leveraging effect on a fund because the fund commits to purchase securities that it does not have to pay for until a later date, which increases the fund’s overall investment exposure and, as a result, its volatility.

Currency Risk – Investing in securities that trade in and receive revenues in foreign currencies creates risk because foreign currencies may decline relative to the U.S. dollar, resulting in a potential loss to a fund. In the case of hedging positions, the U.S. dollar may decline in value relative to the currency that has been hedged.

Sovereign Debt Risk – Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

Treasury Obligations Risk – Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of a fund. Because U.S. Treasury obligations trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. In addition, changes in the credit rating or financial condition of the U.S. government may cause the value of U.S. Treasury Obligations to decline. Although a fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the fund.

U.S. Government Obligations Risk – Certain securities in which a fund may invest, including securities issued by certain government agencies and government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Financial Markets Regulatory Risk – Policy changes by the U.S. government or its regulatory agencies and other governmental actions and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact a fund, including by adversely impacting the fund’s operations, universe of potential investment options, and return potential.

Interest Rate Risk – Debt securities held by a fund may decline in value due to rising interest rates. Macroeconomic factors, such as inflationary trends, can heighten interest rate risk.

Credit Risk – The failure of the issuer of a debt security to pay interest or repay principal in a timely manner may have an adverse impact on a fund’s earnings.

Income Risk – Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. Falling interest rates may cause a fund’s income to decline.

Call Risk – If interest rates fall, issuers of callable debt securities are more likely to prepay prior to the maturity date. A fund may not be able to reinvest the proceeds from the prepayment in investments that will generate the same level of income.

Extension Risk – If interest rates rise, debt securities may be paid in full more slowly than anticipated. Periods of low relative interest rates or inflationary trends may increase the risks associated with rising interest rates.

Derivatives Risk – Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. Derivatives are subject to a number of other risks, such as liquidity risk, interest rate risk, market risk, credit risk, counterparty risk, and selection risk. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value may not correlate perfectly with the underlying asset, rate, or index. Using derivatives may result in losses, possibly in excess of the principal amount invested.

Swaps Risk – A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Leveraging Risk – Certain underlying funds may engage in certain kinds of transactions, including the use of derivatives, that may give rise to a form of leverage. The use of leverage may require a fund to liquidate a portfolio position at a disadvantageous time or may exaggerate the effect of any increase or decrease in the value of a fund’s portfolio securities.

Liquidity Risk – An investment that is difficult to purchase or sell may have an adverse effect on the fund’s returns. Liquid securities can become illiquid during periods of market stress. If a significant amount of the fund’s securities become illiquid, the fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Mortgage-Related and Other Asset-Backed Securities Risk – Investing in mortgage-related or other asset-backed securities involves a variety of risks associated with the credit markets, such as rising or falling interest rates, increases in the rate of defaults or prepayments, and the quality of the pool of mortgages (subprime risk) or other assets that back the security.

Portfolio Turnover Risk – Certain underlying funds may trade portfolio securities frequently, which could result in higher transaction costs and could adversely affect the fund’s performance.

Privately Placed, Rule 144A and Other Exempt Securities Risk – Certain underlying funds may invest in privately placed securities, which are subject to resale restrictions. The market for Rule 144A and other securities exempt from certain registration requirements may be less active than the market for publicly-traded securities. Rule 144A and other exempt securities carry the risk that their liquidity may become impaired and a fund may be unable to dispose of the securities at a desirable time or price.

Repurchase Agreements and Purchase and Sale Contracts Risk – If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, a fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security in either situation and the market value of the security declines, the fund may lose money.

Information Technology Sector Risk – Information technology companies may have limited product lines, markets, financial resources or personnel. Information technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

Collateralized Debt Obligations Risk – In addition to the typical risks associated with fixed-income securities and asset-backed securities, collateralized debt obligations, including CLOs, carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) a fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment return achieved by a fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) the risk of forced “fire sale” liquidation due to technical defaults such as coverage test failures; and (viii) the CDO’s manager may perform poorly.

Non-Diversification Risk – To the extent an underlying fund becomes non-diversified, the underlying fund may invest a larger percentage of its assets in securities issued by or representing a small number of issuers than can a diversified fund. As a result, the underlying fund’s shares may experience greater price volatility and the underlying fund may be more susceptible to the risks associated with these particular issuers or to a single economic, political or regulatory occurrence affecting these issuers, which may negatively impact the underlying fund’s performance.

The following bar chart and table provide an indication of the risks of an investment in the Fund by showing changes in its performance from year to year and by showing how the Fund’s average annual returns for one year, five years and ten years compare with those of a broad-based measure of market performance, the S&P 500 Index. The Fund’s performance also is compared to the Bloomberg U.S. Aggregate Bond Index, which shows how the Fund’s performance compares with the returns of a broad index of investment-grade fixed-rate debt issues, and to the Moderate Composite Index, which shows how the Fund’s performance compares with a composite index composed of the S&P 500 Index (60%) and the Bloomberg U.S. Aggregate Bond Index (40%) in proportions similar to the equity to fixed income allocation of the Fund.

Both the bar chart and the table assume reinvestment of dividends and distributions.

The performance of the Fund will vary from year to year. The Fund’s performance does not reflect the cost of insurance and separate account charges which are imposed under your Contract. If they were included, performance would be reduced. Past performance does not indicate how the Fund will perform in the future.

Prior to October 14, 2016, the Fund was managed pursuant to different investment strategies and known as the AZL MVP Invesco Equity and Income Fund. Consequently, the performance information shown below for periods prior to October 14, 2016, reflects the Fund’s prior investment strategies and not its current investment strategies.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The Fund is offered exclusively as an investment option for certain Contracts. The table below reflects only Fund expenses and does not reflect Contract fees and expenses. If Contract fees and expenses were included, the fees and expenses in the following table would be higher. Please refer to the Contract prospectus for a description of those fees and expenses.

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. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and that you reinvest all dividends and distributions. It does not reflect any Contract fees. If Contract fees were included, the costs shown would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 9% of the average value of its portfolio.

 Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund is a fund of funds that, under normal market conditions, seeks to achieve its investment objective by investing primarily in a combination of three underlying funds:

The AZL Enhanced Bond Index Fund is a bond index fund, and the other two underlying funds are equity funds. Under normal market conditions, the Fund will allocate approximately 60% of its assets in the underlying equity funds and approximately 40% of its assets in the underlying bond index fund. These target allocations represent the Fund’s long-term strategic asset allocation, which is not expected to change under normal market conditions.

The investment results of the underlying funds will vary. As a result, the Manager monitors the actual allocations to the underlying funds daily and periodically adjusts the actual allocations to attempt to achieve the target allocation. Generally, the Manager will seek to maintain the actual fund allocations to target using the cash flows that result from shareholders buying or selling shares in the Fund. However, if cash flows were insufficient to maintain the target allocations, the

Allocation Risk – The Manager’s decisions regarding how the Fund’s assets should be allocated among the various underlying funds, may cause the Fund to underperform other funds with similar investment objectives. There can be no guarantee that investment decisions made by the Manager will produce the desired results. Further, because the Manager has limited discretion to change the underlying fund allocations under normal market conditions, the Fund may underperform comparable funds of funds for which the fund’s manager has such discretion to adjust allocations to underlying funds.

Fund of Funds Risk – The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further, due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any futures and cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

In addition, the Fund bears the investment risks of the investments of the underlying funds. The principal risks associated with the underlying funds include:

Market Risk – The market value of portfolio securities may go up or down, sometimes rapidly and unpredictably. The value of a security or other asset may fluctuate significantly due to factors such as changes in general market conditions, including economic, political, and financial conditions, widespread disease or other public health issues, war, military

Issuer Risk – The value of a security may decline for a number of reasons directly related to the issuer of the security. Further, the value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Selection Risk – Because each underlying fund is actively managed, there can be no guarantee that investment decisions made for the Fund will produce the desired results.

Value Stocks Risk – Value stocks may perform differently from the market as a whole and following a value-oriented investment strategy may cause a fund to at times underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic, and industry developments than the market as a whole and other types of stocks. If the market does not recognize that a selected security is undervalued, the prices of that security might not appreciate as anticipated. Value stocks also may underperform the market for long periods of time.

Capitalization Risk – Investing in small- to mid-sized companies creates risk because smaller companies may have unpredictable or limited earnings, and their securities may be less liquid or experience more volatile prices than those of large companies.

Foreign Securities Risk – Investing in the securities of non-U.S. issuers involves a number of risks, such as fluctuations in currency values, adverse political, social or economic developments, and differences in social and economic developments or policies.

European Investment Risk – Investments in certain countries in the European Union (the “EU”) are susceptible to high political, social, or economic risks due to restrictions on inflation rates, rising debt levels and fiscal and monetary controls. Efforts of the member countries to further unify their economic and monetary policies may increase the potential for the downward movement of one member country’s market to cause a similar effect on other member countries’ markets. Separately, the EU faces issues involving its membership, structure, procedures and policies. The exit of one or more member countries from the EU, such as the exit of the United Kingdom (known as “Brexit”), could place its currency and banking system in jeopardy. An exit by other member countries could likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which may adversely affect a fund’s investments.

When-Issued, Delayed Delivery Securities and Forward Commitments Risk – The purchase or sale of securities on a when issued basis or on a delayed delivery basis or through a forward commitment involves the purchase or sale of securities at an established price with payment and delivery taking place in the future. When-issued and delayed delivery transactions subject a fund to market risk because the value or yield of a security at delivery may be more or less than the purchase price or yield generally available when delivery occurs, and counterparty risk because the fund relies on the buyer or seller, as the case may be, to consummate the transaction. These transactions also have a leveraging effect on a fund because the fund commits to purchase securities that it does not have to pay for until a later date, which increases the fund’s overall investment exposure and, as a result, its volatility.

Emerging Markets Risk – Emerging markets may have less developed or more volatile trading markets and greater likelihood of government restrictions, nationalization, or confiscation than developed countries. Companies in emerging market countries may have less developed legal and accounting systems and generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable which can impede a fund’s ability to evaluate such companies. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. In addition, investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Depositary Receipt Risk – Depositary receipts involve many of the same risks as those associated with direct investment in foreign securities. Investing in these instruments may expose a fund to credit risk with respect to the issuer of the depositary receipt, in addition to the risks of the underlying investment.

Currency Risk – Investing in securities that trade in and receive revenues in foreign currencies creates risk because foreign currencies may decline relative to the U.S. dollar, resulting in a potential loss to a fund.

Derivatives Risk – Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. Derivatives are subject to a number of other risks, such as liquidity risk, interest rate risk, market risk, credit risk, counterparty risk, and selection risk. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value may not correlate perfectly with the underlying asset, rate, or index. Using derivatives may result in losses, possibly in excess of the principal amount invested.

Futures Risk – The value of futures contracts depend primarily upon the price of the securities, indexes, commodities, currencies or other instruments underlying them. Price movements are also influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary, and exchange control programs and policies of governments, and national and international political and economic events and policies. The cost of futures may also be related, in part, to the degree of volatility of the underlying indices, securities, currencies, or other assets. Accordingly, futures on highly volatile indices, securities, currency, or other assets may be more expensive than futures on other investments. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.

Swaps Risk – A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Credit Risk – The failure of the issuer of a debt security to pay interest or repay principal in a timely manner may have an adverse impact on a fund’s earnings.

Liquidity Risk – An investment that is difficult to purchase or sell may have an adverse effect on the fund’s returns. Liquid securities can become illiquid during periods of market stress. If a significant amount of the fund’s securities become illiquid, the fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Interest Rate Risk – Debt securities held by a fund may decline in value due to rising interest rates. Macroeconomic factors, such as inflationary trends, can heighten interest rate risk.

Call Risk – If interest rates fall, issuers of callable debt securities are more likely to prepay prior to the maturity date. A fund may not be able to reinvest the proceeds from the prepayment in investments that will generate the same level of income.

Extension Risk – If interest rates rise, debt securities may be paid in full more slowly than anticipated. Periods of low relative interest rates or inflationary trends may increase the risks associated with rising interest rates.

Leveraging Risk – Certain underlying funds may engage in certain kinds of transactions, including the use of derivatives, that may give rise to a form of leverage. The use of leverage may require a fund to liquidate a portfolio position at a disadvantageous time or may exaggerate the effect of any increase or decrease in the value of a fund’s portfolio securities.

Income Risk – Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. Falling interest rates may cause a fund’s income to decline.

Portfolio Turnover Risk – Certain underlying funds may trade portfolio securities frequently, which could result in higher transaction costs and could adversely affect the fund’s performance.

Sovereign Debt Risk – Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency

Treasury Obligations Risk – Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of a fund. Because U.S. Treasury obligations trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. In addition, changes in the credit rating or financial condition of the U.S. government may cause the value of U.S. Treasury Obligations to decline. Although a fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the fund.

U.S. Government Obligations Risk – Certain securities in which a fund may invest, including securities issued by certain government agencies and government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Financial Markets Regulatory Risk – Policy changes by the U.S. government or its regulatory agencies and other governmental actions and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact a fund, including by adversely impacting the fund’s operations, universe of potential investment options, and return potential.

Mortgage-Related and Other Asset-Backed Securities Risk – Investing in mortgage-related or other asset-backed securities involves a variety of risks associated with the credit markets, such as rising or falling interest rates, increases in the rate of defaults or prepayments, and the quality of the pool of mortgages (subprime risk) or other assets that back the security.

Privately Placed, Rule 144A and Other Exempt Securities Risk – Certain underlying funds may invest in privately placed securities, which are subject to resale restrictions. The market for Rule 144A and other securities exempt from certain registration requirements may be less active than the market for publicly-traded securities. Rule 144A and other exempt securities carry the risk that their liquidity may become impaired and a fund may be unable to dispose of the securities at a desirable time or price.

Collateralized Debt Obligations Risk – In addition to the typical risks associated with fixed-income securities and asset-backed securities, collateralized debt obligations, including CLOs, carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) a fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment return achieved by a fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) the risk of forced “fire sale” liquidation due to technical defaults such as coverage test failures; and (viii) the CDO’s manager may perform poorly.

Repurchase Agreements and Purchase and Sale Contracts Risk – If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, a fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security in either situation and the market value of the security declines, the fund may lose money.

Profitability Investment Risk – High relative profitability stocks may perform differently from the market as a whole and following a profitability-oriented strategy may cause a fund to, at times, underperform equity funds that use other investment strategies.

Information Technology Sector Risk – Information technology companies may have limited product lines, markets, financial resources or personnel. Information technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

The following bar chart and table provide an indication of the risks of an investment in the Fund by showing changes in its performance from year to year and by showing how the Fund’s average annual returns for one year, five years, and ten years compare with those of a broad-based measure of market performance, the S&P 500 Index.

 Fees and Expenses

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The Fund is offered exclusively as an investment option for certain Contracts. The table below reflects only Fund expenses and does not reflect Contract fees and expenses. If Contract fees and expenses were included, the fees and expenses in the following table would be higher. Please refer to the Contract prospectus for a description of those fees and expenses.

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. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and that you reinvest all dividends and distributions. It does not reflect any Contract fees. If Contract fees were included, the costs shown would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 5% of the average value of its portfolio.

The Fund is a fund of funds that, under normal market conditions, seeks to achieve its investment objective by investing approximately 95% of its assets in a combination of two underlying funds:

In addition, under normal market conditions, the Fund will allocate approximately 5% of its assets to the MVP risk management process, described below.

These target allocations represent the Fund’s long-term strategic asset allocation, which is not expected to change under normal market conditions. The investment results of the underlying funds will vary. As a result, the Manager monitors the actual allocations to the underlying funds daily and periodically adjusts the actual allocations to attempt to achieve the target allocation. Generally, the Manager will seek to maintain the underlying fund target allocations using the cash flows that result from shareholders buying or selling shares in the Fund. However, if cash flows were insufficient to maintain the target allocations, the Manager would then buy or sell underlying funds as necessary to attempt to return the Fund to the target allocations. Generally, the actual allocations will not be more than 10% above or below the targets.

Allocation Risk – The Manager’s decisions regarding how the Fund’s assets should be allocated among the various underlying funds, may cause the Fund to underperform other funds with similar investment objectives. There can be no guarantee that investment decisions made by the Manager will produce the desired results. Further, because the Manager has limited discretion to change the underlying fund allocations under normal market conditions, the Fund may underperform comparable funds of funds for which the fund’s manager has such discretion to adjust allocations to underlying funds.

Futures Risk – Because the Fund may utilize futures pursuant to its MVP risk management process, the Fund also is subject to derivatives risk, including risks related to futures. Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. The value of futures contracts depend primarily upon the price of the securities, indexes, commodities, currencies or other instruments underlying them. Price movements are also influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary, and exchange control programs and policies of governments, and national and international political and economic events and policies. The cost of futures may also be related, in part, to the degree of volatility of the underlying indices, securities, currencies, or other assets. Accordingly, futures on highly volatile indices, securities, currency, or other assets may be more expensive than futures on other investments. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.

Volatility Risk – Although the Fund’s investment strategy seeks not to exceed a specific volatility level, certain of the Fund’s investments may appreciate or decrease significantly in value over short periods of time, which may cause the Fund’s net asset value per share to experience significant increases or declines in value over short periods of time. The Fund’s volatility strategy may not produce the desired result and there can be no guarantee that the Fund will maintain volatility at or below its threshold volatility level. Additionally, maintenance of the volatility level will not ensure that the Fund will deliver competitive returns. The use of derivatives in connection with the Fund’s volatility strategy may expose the Fund to losses (some of which may be sudden) that it would not have otherwise been exposed to if it had only invested directly in equity and/or fixed income securities. Further, in some market conditions the Fund may either underperform or outperform as a direct result of the MVP process. The Fund may, for example, outperform in downward trending markets when volatility is high (and the equity allocation low) and underperform in upward trending markets when volatility is high (and the equity allocation low).

Quantitative Investing Risk – The value of securities selected using quantitative analysis can react differently to issuer, political, market, and economic developments than the market as a whole or securities selected using only fundamental analysis. The factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value. In addition, factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model. A quantitative model can be adversely affected by errors or imperfections in the factors or the data on which evaluations are based, or by technical issues with construction or implementation of the model, which in any case may result in a failure of the portfolio to perform as expected or a failure to identify securities that will perform well in the future. Successful operation of a quantitative model is also reliant upon the information technology systems of the Manager or Subadviser, as applicable, and its ability to ensure those systems remain operational and that appropriate disaster recovery procedures are in place. There can be no assurance that the Manager or Subadviser will be successful in maintaining effective and operational trading models and the related hardware and software systems.

Fund of Funds Risk – The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further, due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any futures and cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

In addition, the Fund bears the investment risks of the investments of the underlying funds. The principal risks associated with the underlying funds include:

Market Risk – The market value of portfolio securities may go up or down, sometimes rapidly and unpredictably. The value of a security or other asset may fluctuate significantly due to factors such as changes in general market conditions, including economic, political, and financial conditions, widespread disease or other public health issues, war, military conflict, acts of terrorism, adverse investor sentiment, or instability or other disruptive events in the local, regional or global markets. Certain changes in the U.S. economy, such as a decrease in imports or exports, changes in trade regulations, inflation and/or economic recession, may have an adverse effect on the value of the Fund’s securities.

Issuer Risk – The value of a security may decline for a number of reasons directly related to the issuer of the security. Further, the value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Selection Risk – Because AZL Enhanced Bond Index Fund is actively managed, there can be no guarantee that investment decisions made for the Fund will produce the desired results.

Index Fund Risk – Certain of the underlying funds do not attempt to manage market volatility or reduce the effects of poor performance. In addition, factors such as fund expenses, selection of a representative portfolio, changes in the composition of the index, or the timing of purchases or redemptions of fund shares may affect the correlation between the performance of the index and the fund’s performance.

Sovereign Debt Risk – Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

Treasury Obligations Risk – Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of a fund. Because U.S. Treasury obligations trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. In addition, changes in the credit rating or financial condition of the U.S. government may cause the value of U.S. Treasury Obligations to decline. Although a fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the fund.

U.S. Government Obligations Risk – Certain securities in which a fund may invest, including securities issued by certain government agencies and government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Financial Markets Regulatory Risk – Policy changes by the U.S. government or its regulatory agencies and other governmental actions and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact a fund, including by adversely impacting the fund’s operations, universe of potential investment options, and return potential.

Credit Risk – The failure of the issuer of a debt security to pay interest or repay principal in a timely manner may have an adverse impact on a fund’s earnings.

Interest Rate Risk – Debt securities held by a fund may decline in value due to rising interest rates. Macroeconomic factors, such as inflationary trends, can heighten interest rate risk.

Call Risk – If interest rates fall, issuers of callable debt securities are more likely to prepay prior to the maturity date. A fund may not be able to reinvest the proceeds from the prepayment in investments that will generate the same level of income.

Extension Risk – If interest rates rise, debt securities may be paid in full more slowly than anticipated. Periods of low relative interest rates or inflationary trends may increase the risks associated with rising interest rates.

Income Risk – Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. Falling interest rates may cause a fund’s income to decline.

Foreign Securities Risk – Investing in the securities of non-U.S. issuers involves a number of risks, such as fluctuations in currency values, adverse political, social or economic developments, and differences in social and economic developments or policies.

When-Issued, Delayed Delivery Securities and Forward Commitments Risk – The purchase or sale of securities on a when issued basis or on a delayed delivery basis or through a forward commitment involves the purchase or sale of securities at an established price with payment and delivery taking place in the future. When-issued and delayed delivery transactions subject a fund to market risk because the value or yield of a security at delivery may be more or less than the purchase price or yield generally available when delivery occurs, and counterparty risk because the fund relies on the buyer or seller, as the case may be, to consummate the transaction. These transactions also have a leveraging effect on a fund

Depositary Receipt Risk – Depositary receipts involve many of the same risks as those associated with direct investment in foreign securities. Investing in these instruments may expose a fund to credit risk with respect to the issuer of the depositary receipt, in addition to the risks of the underlying investment.

Emerging Markets Risk – Emerging markets may have less developed or more volatile trading markets and greater likelihood of government restrictions, nationalization, or confiscation than developed countries. Companies in emerging market countries may have less developed legal and accounting systems and generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable which can impede a fund’s ability to evaluate such companies. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. In addition, investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Currency Risk – Investing in securities that trade in and receive revenues in foreign currencies creates risk because foreign currencies may decline relative to the U.S. dollar, resulting in a potential loss to a fund. In the case of hedging positions, the U.S. dollar may decline in value relative to the currency that has been hedged.

Derivatives Risk – Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. Derivatives are subject to a number of other risks, such as liquidity risk, interest rate risk, market risk, credit risk, counterparty risk, and selection risk. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value may not correlate perfectly with the underlying asset, rate, or index. Using derivatives may result in losses, possibly in excess of the principal amount invested.

Swaps Risk – A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Leveraging Risk – Certain underlying funds may engage in certain kinds of transactions, including the use of derivatives, that may give rise to a form of leverage. The use of leverage may require a fund to liquidate a portfolio position at a disadvantageous time or may exaggerate the effect of any increase or decrease in the value of a fund’s portfolio securities.

Capitalization Risk – Investing in small- to mid-sized companies creates risk because smaller companies may have unpredictable or limited earnings, and their securities may be less liquid or experience more volatile prices than those of large companies.

Information Technology Sector Risk – Information technology companies may have limited product lines, markets, financial resources or personnel. Information technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

Liquidity Risk – An investment that is difficult to purchase or sell may have an adverse effect on the fund’s returns. Liquid securities can become illiquid during periods of market stress. If a significant amount of the fund’s securities become illiquid, the fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Privately Placed, Rule 144A and Other Exempt Securities Risk – Certain underlying funds may invest in privately placed securities, which are subject to resale restrictions. The market for Rule 144A and other securities exempt from

Portfolio Turnover Risk – Certain underlying funds may trade portfolio securities frequently, which could result in higher transaction costs and could adversely affect the fund’s performance.

Mortgage-Related and Other Asset-Backed Securities Risk – Investing in mortgage-related or other asset-backed securities involves a variety of risks associated with the credit markets, such as rising or falling interest rates, increases in the rate of defaults or prepayments, and the quality of the pool of mortgages (subprime risk) or other assets that back the security.

Repurchase Agreements and Purchase and Sale Contracts Risk – If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, a fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security in either situation and the market value of the security declines, the fund may lose money.

Collateralized Debt Obligations Risk – In addition to the typical risks associated with fixed-income securities and asset-backed securities, collateralized debt obligations, including CLOs, carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) a fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment return achieved by a fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) the risk of forced “fire sale” liquidation due to technical defaults such as coverage test failures; and (viii) the CDO’s manager may perform poorly.

The following bar chart and table provide an indication of the risks of an investment in the Fund by showing changes in its performance from year to year and by showing how the Fund’s average annual returns for one year, five years and ten years compare with those of a broad-based measure of market performance, the MSCI World Index. The Fund’s performance also is compared to the returns of the Bloomberg U.S. Aggregate Bond Index and the Global Balanced Composite Index, which are relevant to the Fund because they have characteristics similar to the Fund’s investment strategies. The Global Balanced Composite Index is composed of the MSCI World Index (50%) and Bloomberg U.S. Aggregate Bond Index (50%).

Both the bar chart and the table assume reinvestment of dividends and distributions.

The performance of the Fund will vary from year to year. The Fund’s performance does not reflect the cost of insurance and separate account charges which are imposed under your Contract. If they were included, performance would be reduced. Past performance does not indicate how the Fund will perform in the future.

Prior to November 15, 2019, the Fund was managed pursuant to different investment strategies and known as the AZL MVP BlackRock Global Strategy Plus Fund, and prior to October 14, 2016, the Fund was managed pursuant to different investment strategies and known as the AZL MVP BlackRock Global Allocation Fund. Consequently, the performance information shown below for prior periods reflects the Fund’s prior investment strategies and not its current investment strategies.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The Fund is offered exclusively as an investment option for certain Contracts. The table below reflects only Fund expenses and does not reflect Contract fees and expenses. If Contract fees and expenses were included, the fees and expenses in the following table would be higher. Please refer to the Contract prospectus for a description of those fees and expenses.

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. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and that you reinvest all dividends and distributions. It does not reflect any Contract fees. It reflects the management fee waiver agreement for the first year. If Contract fees were included, the costs shown would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 9% of the average value of its portfolio.

 Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund is a fund of funds that, under normal market conditions, seeks to achieve its investment objective by investing approximately 95% of its assets in a combination of three underlying funds:

In addition, under normal market conditions, the Fund will allocate approximately 5% of its assets to the MVP risk management process, described below.

Allocation Risk – The Manager’s decisions regarding how the Fund’s assets should be allocated among the various underlying funds, may cause the Fund to underperform other funds with similar investment objectives. There can be no guarantee that investment decisions made by the Manager will produce the desired results. Further, because the Manager has limited discretion to change the underlying fund allocations under normal market conditions, the Fund may underperform comparable funds of funds for which the fund’s manager has such discretion to adjust allocations to underlying funds.

Futures Risk – Because the Fund may utilize futures pursuant to its MVP risk management process, the Fund also is subject to derivatives risk, including risks related to futures. Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. The value of futures contracts depend primarily upon the price of the securities, indexes, commodities, currencies or other instruments underlying them. Price movements are also influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary, and exchange control programs and policies of governments, and national and international political and economic events and policies. The cost of futures may also be related, in part, to the degree of volatility of the underlying indices, securities, currencies, or other assets. Accordingly, futures on highly volatile indices, securities, currency, or other assets may be more expensive than futures on other investments. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.

Volatility Risk – Although the Fund’s investment strategy seeks not to exceed a specific volatility level, certain of the Fund’s investments may appreciate or decrease significantly in value over short periods of time, which may cause the Fund’s net asset value per share to experience significant increases or declines in value over short periods of time. The Fund’s volatility strategy may not produce the desired result and there can be no guarantee that the Fund will maintain volatility at or below its threshold volatility level. Additionally, maintenance of the volatility level will not ensure that the Fund will deliver competitive returns. The use of derivatives in connection with the Fund’s volatility strategy may expose the Fund to losses (some of which may be sudden) that it would not have otherwise been exposed to if it had only invested directly in equity and/or fixed income securities. Further, in some market conditions the Fund may either underperform or outperform as a direct result of the MVP process. The Fund may, for example, outperform in downward trending markets when volatility is high (and the equity allocation low) and underperform in upward trending markets when volatility is high (and the equity allocation low).

Quantitative Investing Risk – The value of securities selected using quantitative analysis can react differently to issuer, political, market, and economic developments than the market as a whole or securities selected using only fundamental analysis. The factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value. In addition, factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model. A quantitative model can be adversely affected by errors or imperfections in the factors or the data on which evaluations are based, or by technical issues with construction or implementation of the model, which in any case may result in a failure of the portfolio to perform as expected or a failure to identify securities that will perform well in the future. Successful operation of a quantitative model is also reliant upon the information technology systems of the Manager or Subadviser, as applicable, and its ability to ensure those systems remain operational and that appropriate

Fund of Funds Risk – The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further, due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any futures and cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

In addition, the Fund bears the investment risks of the investments of the underlying funds. The principal risks associated with the underlying funds include:

Market Risk – The market value of portfolio securities may go up or down, sometimes rapidly and unpredictably. The value of a security or other asset may fluctuate significantly due to factors such as changes in general market conditions, including economic, political, and financial conditions, widespread disease or other public health issues, war, military conflict, acts of terrorism, adverse investor sentiment, or instability or other disruptive events in the local, regional or global markets. Certain changes in the U.S. economy, such as a decrease in imports or exports, changes in trade regulations, inflation and/or economic recession, may have an adverse effect on the value of the Fund’s securities.

Issuer Risk – The value of a security may decline for a number of reasons directly related to the issuer of the security. Further, the value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Selection Risk – Because each underlying fund is actively managed, there can be no guarantee that investment decisions made for the Fund will produce the desired results.

Value Stocks Risk – Value stocks may perform differently from the market as a whole and following a value-oriented investment strategy may cause a fund to at times underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic, and industry developments than the market as a whole and other types of stocks. If the market does not recognize that a selected security is undervalued, the prices of that security might not appreciate as anticipated. Value stocks also may underperform the market for long periods of time.

Capitalization Risk – Investing in small- to mid-sized companies creates risk because smaller companies may have unpredictable or limited earnings, and their securities may be less liquid or experience more volatile prices than those of large companies.

Foreign Securities Risk – Investing in the securities of non-U.S. issuers involves a number of risks, such as fluctuations in currency values, adverse political, social or economic developments, and differences in social and economic developments or policies.

When-Issued, Delayed Delivery Securities and Forward Commitments Risk – The purchase or sale of securities on a when issued basis or on a delayed delivery basis or through a forward commitment involves the purchase or sale of securities at an established price with payment and delivery taking place in the future. When-issued and delayed delivery transactions subject a fund to market risk because the value or yield of a security at delivery may be more or less than the purchase price or yield generally available when delivery occurs, and counterparty risk because the fund relies on the buyer or seller, as the case may be, to consummate the transaction. These transactions also have a leveraging effect on a fund because the fund commits to purchase securities that it does not have to pay for until a later date, which increases the fund’s overall investment exposure and, as a result, its volatility.

European Investment Risk – Investments in certain countries in the European Union (the “EU”) are susceptible to high political, social, or economic risks due to restrictions on inflation rates, rising debt levels and fiscal and monetary controls. Efforts of the member countries to further unify their economic and monetary policies may increase the potential for the downward movement of one member country’s market to cause a similar effect on other member countries’ markets. Separately, the EU faces issues involving its membership, structure, procedures and policies. The exit of one or more member countries from the EU, such as the exit of the United Kingdom (known as “Brexit”), could place its currency and banking system in jeopardy. An exit by other member countries could likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which may adversely affect a fund’s investments.

Emerging Markets Risk – Emerging markets may have less developed or more volatile trading markets and greater likelihood of government restrictions, nationalization, or confiscation than developed countries. Companies in emerging market countries may have less developed legal and accounting systems and generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable which can impede a fund’s ability to evaluate such companies. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. In addition, investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Depositary Receipt Risk – Depositary receipts involve many of the same risks as those associated with direct investment in foreign securities. Investing in these instruments may expose a fund to credit risk with respect to the issuer of the depositary receipt, in addition to the risks of the underlying investment.

Currency Risk – Investing in securities that trade in and receive revenues in foreign currencies creates risk because foreign currencies may decline relative to the U.S. dollar, resulting in a potential loss to a fund.

Derivatives Risk – Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. Derivatives are subject to a number of other risks, such as liquidity risk, interest rate risk, market risk, credit risk, counterparty risk, and selection risk. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value may not correlate perfectly with the underlying asset, rate, or index. Using derivatives may result in losses, possibly in excess of the principal amount invested.

Swaps Risk – A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Credit Risk – The failure of the issuer of a debt security to pay interest or repay principal in a timely manner may have an adverse impact on a fund’s earnings.

Liquidity Risk – An investment that is difficult to purchase or sell may have an adverse effect on the fund’s returns. Liquid securities can become illiquid during periods of market stress. If a significant amount of the fund’s securities become illiquid, the fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Interest Rate Risk – Debt securities held by a fund may decline in value due to rising interest rates. Macroeconomic factors, such as inflationary trends, can heighten interest rate risk.

Call Risk – If interest rates fall, issuers of callable debt securities are more likely to prepay prior to the maturity date. A fund may not be able to reinvest the proceeds from the prepayment in investments that will generate the same level of income.

Extension Risk – If interest rates rise, debt securities may be paid in full more slowly than anticipated. Periods of low relative interest rates or inflationary trends may increase the risks associated with rising interest rates.

Leveraging Risk – Certain underlying funds may engage in certain kinds of transactions, including the use of derivatives, that may give rise to a form of leverage. The use of leverage may require a fund to liquidate a portfolio position at a disadvantageous time or may exaggerate the effect of any increase or decrease in the value of a fund’s portfolio securities.

Income Risk – Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. Falling interest rates may cause a fund’s income to decline.

Portfolio Turnover Risk – Certain underlying funds may trade portfolio securities frequently, which could result in higher transaction costs and could adversely affect the fund’s performance.

Sovereign Debt Risk – Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

Treasury Obligations Risk – Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of a fund. Because U.S. Treasury obligations trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. In addition, changes in the credit rating or financial condition of the U.S. government may cause the value of U.S. Treasury Obligations to decline. Although a fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the fund.

U.S. Government Obligations Risk – Certain securities in which a fund may invest, including securities issued by certain government agencies and government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Financial Markets Regulatory Risk – Policy changes by the U.S. government or its regulatory agencies and other governmental actions and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact a fund, including by adversely impacting the fund’s operations, universe of potential investment options, and return potential.

Mortgage-Related and Other Asset-Backed Securities Risk – Investing in mortgage-related or other asset-backed securities involves a variety of risks associated with the credit markets, such as rising or falling interest rates, increases in the rate of defaults or prepayments, and the quality of the pool of mortgages (subprime risk) or other assets that back the security.

Privately Placed, Rule 144A and Other Exempt Securities Risk – Certain underlying funds may invest in privately placed securities, which are subject to resale restrictions. The market for Rule 144A and other securities exempt from certain registration requirements may be less active than the market for publicly-traded securities. Rule 144A and other exempt securities carry the risk that their liquidity may become impaired and a fund may be unable to dispose of the securities at a desirable time or price.

Collateralized Debt Obligations Risk – In addition to the typical risks associated with fixed-income securities and asset-backed securities, collateralized debt obligations, including CLOs, carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) a fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment return achieved by a fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) the risk of forced “fire sale” liquidation due to technical defaults such as coverage test failures; and (viii) the CDO’s manager may perform poorly.

Repurchase Agreements and Purchase and Sale Contracts Risk – If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, a fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security in either situation and the market value of the security declines, the fund may lose money.

Profitability Investment Risk – High relative profitability stocks may perform differently from the market as a whole and following a profitability-oriented strategy may cause a fund to, at times, underperform equity funds that use other investment strategies.

Information Technology Sector Risk – Information technology companies may have limited product lines, markets, financial resources or personnel. Information technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

The following bar chart and table provide an indication of the risks of an investment in the Fund by showing changes in its performance from year to year and by showing how the Fund’s average annual returns for one year, five years and ten years compare with those of a broad-based measure of market performance, the S&P 500 Index. The Fund’s performance also is compared to the Bloomberg U.S. Aggregate Bond Index, which shows how the Fund’s performance compares with the returns of a broad index of investment-grade fixed-rate debt issues, and to a Moderate Composite Index, which shows how the Fund’s performance compares with a composite index composed of the S&P 500 Index (60%) and the Bloomberg U.S. Aggregate Bond Index (40%) in proportions similar to the equity to fixed income allocation of the Fund.

Both the bar chart and the table assume reinvestment of dividends and distributions.

The performance of the Fund will vary from year to year. The Fund’s performance does not reflect the cost of insurance and separate account charges which are imposed under your Contract. If they were included, performance would be reduced. Past performance does not indicate how the Fund will perform in the future.

Principal Investment Strategies of the Fund

The Fund is a fund of funds that, under normal market conditions, seeks to achieve its investment objective by investing approximately 95% of its assets in an underlying fund, the AZL Fidelity Institutional Asset Management^® Multi-Strategy Fund, managed by the underlying fund’s Subadviser, FIAM LLC. Under normal market conditions, the underlying fund seeks to achieve its objective by investing in a combination of two strategies. Approximately 60% of the underlying fund’s assets will be invested primarily in investment-grade debt securities (the “Fixed-Income Strategy”), and approximately

Allocation Risk – The Manager’s decisions regarding how the Fund’s assets should be allocated among the various underlying funds, may cause the Fund to underperform other funds with similar investment objectives. There can be no guarantee that investment decisions made by the Manager will produce the desired results. Further, because the Manager has limited discretion to change the underlying fund allocations under normal market conditions, the Fund may underperform comparable funds of funds for which the fund’s manager has such discretion to adjust allocations to underlying funds.

Futures Risk – Because the Fund may utilize futures pursuant to its MVP risk management process, the Fund also is subject to derivatives risk, including risks related to futures. Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. The value of futures contracts depend primarily upon the price of the securities, indexes, commodities, currencies or other instruments underlying them. Price movements are also influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary, and exchange control programs and policies of governments, and national and international political and economic events and policies. The cost of futures may also be related, in part, to the degree of volatility of the underlying indices, securities, currencies, or other assets. Accordingly, futures on highly volatile

Volatility Risk – Although the Fund’s investment strategy seeks not to exceed a specific volatility level, certain of the Fund’s investments may appreciate or decrease significantly in value over short periods of time, which may cause the Fund’s net asset value per share to experience significant increases or declines in value over short periods of time. The Fund’s volatility strategy may not produce the desired result and there can be no guarantee that the Fund will maintain volatility at or below its threshold volatility level. Additionally, maintenance of the volatility level will not ensure that the Fund will deliver competitive returns. The use of derivatives in connection with the Fund’s volatility strategy may expose the Fund to losses (some of which may be sudden) that it would not have otherwise been exposed to if it had only invested directly in equity and/or fixed income securities. Further, in some market conditions the Fund may either underperform or outperform as a direct result of the MVP process. The Fund may, for example, outperform in downward trending markets when volatility is high (and the equity allocation low) and underperform in upward trending markets when volatility is high (and the equity allocation low).

Quantitative Investing Risk – The value of securities selected using quantitative analysis can react differently to issuer, political, market, and economic developments than the market as a whole or securities selected using only fundamental analysis. The factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value. In addition, factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model. A quantitative model can be adversely affected by errors or imperfections in the factors or the data on which evaluations are based, or by technical issues with construction or implementation of the model, which in any case may result in a failure of the portfolio to perform as expected or a failure to identify securities that will perform well in the future. Successful operation of a quantitative model is also reliant upon the information technology systems of the Manager or Subadviser, as applicable, and its ability to ensure those systems remain operational and that appropriate disaster recovery procedures are in place. There can be no assurance that the Manager or Subadviser will be successful in maintaining effective and operational trading models and the related hardware and software systems.

Fund of Funds Risk – The Fund, as a shareholder of the underlying fund, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying fund. Further, due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying fund and any futures and cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying fund.

In addition, the Fund bears the investment risks of the investments of the underlying fund. The principal risks associated with the underlying fund include:

Market Risk – The market value of portfolio securities may go up or down, sometimes rapidly and unpredictably. The value of a security or other asset may fluctuate significantly due to factors such as changes in general market conditions, including economic, political, and financial conditions, widespread disease or other public health issues, war, military conflict, acts of terrorism, adverse investor sentiment, or instability or other disruptive events in the local, regional or global markets. Certain changes in the U.S. economy, such as a decrease in imports or exports, changes in trade regulations, inflation and/or economic recession, may have an adverse effect on the value of the Fund’s securities.

Issuer Risk – The value of a security may decline for a number of reasons directly related to the issuer of the security. Further, the value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Selection Risk – Because the underlying fund is actively managed, there can be no guarantee that investment decisions made for the Fund will produce the desired results.

Sovereign Debt Risk – Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

U.S. Government Obligations Risk – Certain securities in which a fund may invest, including securities issued by certain government agencies and government sponsored enterprises, are not guaranteed by the U.S. Government or supported by

Financial Markets Regulatory Risk – Policy changes by the U.S. government or its regulatory agencies and other governmental actions and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact a fund, including by adversely impacting the fund’s operations, universe of potential investment options, and return potential.

Treasury Obligations Risk – Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of a fund. Because U.S. Treasury obligations trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. In addition, changes in the credit rating or financial condition of the U.S. government may cause the value of U.S. Treasury Obligations to decline. Although a fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the fund.

Interest Rate Risk – Debt securities held by a fund may decline in value due to rising interest rates. Macroeconomic factors, such as inflationary trends, can heighten interest rate risk.

Credit Risk – The failure of the issuer of a debt security to pay interest or repay principal in a timely manner may have an adverse impact on a fund’s earnings.

Call Risk – If interest rates fall, issuers of callable debt securities are more likely to prepay prior to the maturity date. A fund may not be able to reinvest the proceeds from the prepayment in investments that will generate the same level of income.

Extension Risk – If interest rates rise, debt securities may be paid in full more slowly than anticipated. Periods of low relative interest rates or inflationary trends may increase the risks associated with rising interest rates.

Income Risk – Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. Falling interest rates may cause a fund’s income to decline.

Privately Placed, Rule 144A and Other Exempt Securities Risk – The underlying funds may invest in privately placed securities, which are subject to resale restrictions. The market for Rule 144A and other securities exempt from certain registration requirements may be less active than the market for publicly-traded securities. Rule 144A and other exempt securities carry the risk that their liquidity may become impaired and a fund may be unable to dispose of the securities at a desirable time or price.

Foreign Securities Risk – Investing in the securities of non-U.S. issuers involves a number of risks, such as fluctuations in currency values, adverse political, social or economic developments, and differences in social and economic developments or policies.
