Voya Investment Grade Credit Fund

Investment Objective

The Fund seeks to maximize total return. Total return is a combination of income and capital appreciation.

Fees and Expenses of the Fund

These tables describe the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in Voya mutual funds. More information about these and other discounts is available from your financial intermediary and in the discussion in the Sales Charges section of the Prospectus (page 35), in Appendix A to the Prospectus, or the Purchase, Exchange, and Redemption of Shares section of the Statement of Additional Information (page 73).

A contingent deferred sales charge of 1.00% is assessed on certain redemptions of Class A shares made within 12 months after purchase where no initial sales charge was paid at the time of purchase as part of an investment of $500,000 or more.

Voya Investments, LLC (the “ Investment Adviser ” ) is contractually obligated to limit expenses to 0.90%, 0.65%, 0.63%, and 0.65% for Class A, Class I, Class R6, and Class W shares, respectively, through August 1, 2024. The limitation does not extend to interest, taxes, investment-related costs, leverage expenses, extraordinary expenses, and Acquired Fund Fees and Expenses. This limitation is subject to possible recoupment by the Investment Adviser within 36 months of the waiver or reimbursement. The amount of the recoupment is limited to the lesser of the amounts that would be recoupable under : (i) the expense limitation in effect at the time of the waiver or reimbursement; or (ii) the expense limitation in effect at the time of recoupment. Termination or modification of these obligations requires approval by the Fund’s Board of Trustees (the “Board”).

Expense Example

This Example is intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example shows costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Example also assumes that your investment had a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the three-, five-, and ten-year periods. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class	Share Status		1 Yr	3 Yrs	5 Yrs	10 Yrs
A	Sold or Held	$	340	547	771	1,414
I	Sold or Held	$	66	210	367	822
R6	Sold or Held	$	64	208	365	820
W	Sold or Held	$	66	225	398	899

Voya Investment Grade Credit Fund

The Example does not reflect sales charges (loads) on reinvested dividends (and other distributions). If these sales charges (loads) were included, your costs would be higher.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund's performance.

During the most recent fiscal year, the Fund's portfolio turnover rate was 269% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in investment-grade fixed-income securities. The Fund will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Investment-grade fixed-income securities, at the time of purchase, are rated at least Baa3 by Moody’s Investors Service, Inc. ( “ Moody's ” ), BBB- by S&P Global Ratings ( “ S & P ” ) , BBB- by Fitch Ratings ( “ Fitch ” ) , or have an equivalent rating by a Nationally Recognized Statistical Rating Organization (“NRSRO”), or, if unrated, are determined by the sub-adviser (the “Sub-Adviser”) to be of comparable quality. The Fund may concentrate its portfolio investments in any one industry or group of industries under certain circumstances. Generally, the Fund will not invest in a security if, after the investment, more than 25% of its total assets would be invested in one or more issuers conducting their principal business activities in the same industry. However, the Fund may invest between 25% and 35% of its total assets in the securities of any one industry group or group of industries, if at the time of investment, that industry group or group of industries represents 20% or more of the Fund’s primary benchmark index, the Bloomberg U.S. Corporate Index (the “ Index ” ) . As of June 30, 2023 , the banking industry represented 20% or more of the Index.

The securities that the Fund may invest in include, but are not limited to, the following:

•

debt instruments issued by U.S. and foreign (non-U.S.) entities that are denominated in U.S. or foreign (non-U.S.) currencies, including, but not limited to, collateralized debt obligations, collateralized loan obligations (“CLOs”), convertible bonds, collateralized mortgage obligations and U.S. and foreign (non-U.S.) mortgage-backed and asset-backed debt instruments;

•

debt instruments that are denominated in U.S. or foreign (non-U.S.) currencies and issued or guaranteed by the U.S. government and foreign (non-U.S.) governments and their agencies and instrumentalities;

•

preferred stocks;

•

money market instruments; and

•

municipal bonds.

Generally, the Sub-Adviser maintains a dollar-weighted average duration between three and ten years for the Fund. Duration is a commonly used measure of risk in debt instruments as it incorporates multiple features of debt instruments (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rates. Duration is a weighted average of the times that interest payments and the final return of principal are received. The weights are the amounts of the payments discounted by the yield-to-maturity of the debt instrument. Duration is expressed as a number of years. The bigger the duration number, the greater the interest rate risk or reward for the debt instrument prices. For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%.

The Fund may also invest up to 10% of its assets in high-yield (high risk) debt instruments, commonly referred to as “junk bonds.” High-yield debt instruments are debt instruments that, at the time of purchase, are not investment-grade fixed-income securities as defined above. High-yield debt instruments, at the time of purchase, are rated at least B3 by Moody’s, B- by S&P, B- by Fitch, or have an equivalent rating by a NRSRO, or, if unrated, are determined by the Sub-Adviser to be of comparable quality.

The Fund may invest in real estate securities including real estate investment trusts (“REITs”).

The Fund may also engage in dollar roll transactions, repurchase agreements and reverse repurchase agreements, options, futures and forward contracts involving securities, securities indices, foreign currencies, interest rates, and swap agreements, including credit default swaps. The Fund typically uses derivatives to reduce exposure to other risks, such as interest rate or currency risk, to substitute for taking a position in the underlying asset, and/or to enhance returns in the Fund.

Voya Investment Grade Credit Fund

The Sub-Adviser believes that relationships between the drivers of debt instrument returns change over time and that recognizing this is key to managing such assets. Therefore, the Sub-Adviser employs a dynamic investment process that seeks to balance top-down macro economic considerations and fundamental bottom-up analysis during the steps of its investment process: sector allocation, security selection, duration, and yield curve management. This includes utilizing proprietary qualitative analysis along with quantitative tools throughout the portfolio construction process.

In evaluating investments for the Fund, the Sub-Adviser takes into account a wide variety of factors and considerations to determine whether any or all of those factors or considerations might have a material effect on the value, risks, or prospects of an investment. Among the factors considered, the Sub-Adviser expects typically to take into account environmental, social, and governance (“ESG”) factors to determine whether one or more factors may have a material effect. In considering ESG factors, the Sub-Adviser intends to rely primarily on factors identified through its proprietary empirical research and on third-party evaluations of an issuer’s ESG standing. ESG factors will be only one of many considerations in the Sub-Adviser’s evaluation of any potential investment; the extent to which ESG factors will affect the Sub-Adviser’s decision to invest in an issuer, if at all, will depend on the analysis and judgment of the Sub-Adviser.

The Fund may also invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder (“1940 Act”).

The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others.

The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets.

Principal Risks

You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds. The principal risks are presented in alphabetical order to facilitate readability, and their order does not imply that the realization of one risk is more likely to occur or have a greater adverse impact than another risk.

Bank Instruments: Bank instruments include certificates of deposit, fixed time deposits, bankers’ acceptances, and other debt and deposit-type obligations issued by banks. Changes in economic, regulatory, or political conditions, or other events that affect the banking industry may have an adverse effect on bank instruments or banking institutions that serve as counterparties in transactions with the Fund. In the event of a bank insolvency or failure, the Fund may be considered a general creditor of the bank, and it might lose some or all of the funds deposited with the bank. Even where it is recognized that a bank might be in danger of insolvency or failure, the Fund might not be able to withdraw or transfer its money from the bank in time to avoid any adverse effects of the insolvency or failure.

Collateralized Loan Obligations and Other Collateralized Obligations: A CLO is an obligation of a trust or other special purpose vehicle typically collateralized by a pool of loans, which may include senior secured and unsecured loans and subordinate corporate loans, including loans that may be rated below investment grade, or equivalent unrated loans. CLOs may incur management fees and administration fees. The risks of investing in a CLO depend largely on the type of the collateral held in the CLO portfolio and the tranche of securities in which the Fund, and can generally be summarized as a combination of economic risks of the underlying loans combined with the risks associated with the CLO structure governing the priority of payments, and include interest rate risk, credit risk, liquidity risk, prepayment and extension risk, and the risk of default of the underlying asset, among others.

Company: The price of a company’s stock could decline or underperform for many reasons , including, among others, poor management, financial problems, reduced demand for the company’s goods or services, regulatory fines and judgments, or business challenges. If a company is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, its stock could become worthless.

Concentration (Index): To the extent that the Fund’s index “ concentrates, ” as that term is defined in the 1940 Act, in the securities of a particular industry or group of industries, the Fund may allocate its investments to approximately the same extent as the index. As a result, the Fund may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters, affecting issuers in a particular industry or group of industries, and if securities of such industry or group of industries fall out of favor, the Fund could underperform, or be more volatile than, a fund that is more broadly invested across industries.

Banking Industry: Investments in companies involved in the banking industry may be subject to credit risk, interest rate risk, and regulatory risk, among others. Banks and other financial institutions can be affected by such factors as downturns in the U.S. and foreign (non-U.S.) economies and general economic cycles, fiscal and monetary policy, adverse developments in the real estate market, the deterioration or failure of other financial institutions, and changes in banking or securities regulations.

Covenant-Lite Loans: Loans in which the Fund may invest or to which the Fund may gain exposure indirectly through its investments in collateralized debt obligations, CLOs or other types of structured securities may be considered “covenant-lite” loans. Covenant-lite refers to loans which do not incorporate traditional performance-based financial maintenance covenants. Covenant-lite does not refer to a loan’s seniority in a borrower’s capital structure nor to a lack of the benefit from a legal pledge of the borrower’s assets and does not necessarily correlate to the overall credit quality of the borrower. Covenant-lite loans generally do not include terms which allow a lender to take action based on a borrower’s performance relative to its covenants. Such actions may include the ability to renegotiate and/or re-set the credit spread on the loan with a borrower, and even to declare a default or force the borrower into bankruptcy restructuring if certain criteria are breached. Covenant-lite loans typically still provide lenders with other covenants that restrict a borrower from incurring additional debt or engaging in certain actions. Such covenants can only be breached by an affirmative action of the borrower, rather than by a deterioration in the borrower’s financial condition. Accordingly, the Fund may have fewer rights against a borrower when it invests in, or has exposure to, covenant-lite loans and, accordingly, may have a greater risk of loss on such investments as compared to investments in, or exposure to, loans with additional or more conventional covenants.

Credit: The Fund could lose money if the issuer or guarantor of a debt instrument in which the Fund invests , or the counterparty to a derivative contract the Fund entered into, is unable or unwilling, or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations . Asset-backed (including mortgage-backed) securities that are not issued by U.S. government agencies may have a greater risk of default because they are not guaranteed by either the U.S. government or an agency or instrumentality of the U.S. government. The credit quality of typical asset-backed securities depends primarily on the credit quality of the underlying assets and the structural support (if any) provided to the securities.

Credit Default Swaps: The Fund may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a credit default swap is generally obligated to pay the seller an upfront or a periodic stream of payments over the term of the contract until a credit event, such as a default , on a reference obligation has occurred . If a credit event occurs, the seller generally must pay the buyer the “ par value ” ( full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount if the swap is cash settled. As a seller of a credit default swap, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, valuation, liquidity, and leveraging risks and the risk that the swap may not correlate with its reference obligation as expected. Certain standardized credit default swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that it will achieve that result, and, in the meantime, central clearing and related requirements expose the Fund to new kinds of costs and risks. In addition, credit default swaps expose the Fund to the risk of improper valuation.

Currency: To the extent that the Fund invests directly or indirectly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged by the Fund through foreign currency exchange transactions.

Voya Investment Grade Credit Fund

Environmental, Social, and Governance (Fixed Income): The Sub-Adviser’s consideration of ESG factors in selecting investments for the Fund is based on information that is not standardized, some of which can be qualitative and subjective by nature . The Sub-Adviser’s assessment of ESG factors in respect of obligations of an issuer may rely on third party data that might be incorrect or based on incomplete or inaccurate information. There is no minimum percentage of the Fund’s assets that will be invested in obligations of issuers that the Sub-Adviser views favorably in light of ESG factors, and the Sub-Adviser may choose not to invest in obligations of issuers that compare favorably to obligations of other issuers on the basis of ESG factors. It is possible that the Fund will have less exposure to obligations of certain issuers due to the Sub-Adviser’s assessment of ESG factors than other comparable mutual funds. There can be no assurance that an investment selected by the Sub-Adviser , which includes its consideration of ESG factors, will provide more favorable investment performance than another potential investment, and such an investment may, in fact, underperform other potential investments.

Foreign (Non-U.S.) Investments: Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due, in part, to: smaller markets; differing reporting, accounting, auditing, and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions (or the threat of new or modified sanctions) or other measures by the U.S. or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country, or region may adversely impact investments or issuers in another market, country, or region.

High-Yield Securities: Lower - quality securities (including securities that are or have fallen below investment grade and are classified as “junk bonds” or “high-yield securities”) have greater credit risk and liquidity risk than higher-quality (investment grade) securities, and their issuers' long-term ability to make payments is considered speculative. Prices of lower-quality bonds or other debt instruments are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity risk and price volatility.

Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other debt instruments ; conversely, values generally rise as market interest rates fall. Interest rate risk is generally greater for debt instruments than floating-rate instruments. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is to changes in market interest rates. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. As of the date of this Prospectus, the U.S. has been experiencing a rising market interest rate environment, which may increase the Fund’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose debt and related markets to heightened volatility. To the extent that the Fund invests in debt instruments, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so and may lower returns. If dealer capacity in debt markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in the debt markets. Further, recent and potential future changes in government policy may affect interest rates. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose debt and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose debt and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Fund’s operations and return potential.

Investment Model: The Sub-Adviser ’s proprietary investment model may not adequately take into account existing or unforeseen market factors or the interplay between such factors, and there is no guarantee that the use of a proprietary investment model will result in effective investment decisions for the Fund. Funds that are actively managed, in whole or in part, according to a quantitative investment model (or that utilize artificial intelligence) can perform differently from the market, based on the investment model and the factors used in the analysis, the weight placed on each factor, and changes from the factors’ historical trends. Mistakes in the construction and implementation of the investment models (including, for example, data problems and/or software issues) may create errors or limitations that might go undetected or are discovered only after the errors or limitations have negatively impacted performance.

Liquidity: If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund’s manager might wish to sell, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Fund to the risk that the prices at which it sells illiquid securities will be less than the prices at which they were valued when held by the Fund, which could cause the Fund to lose money. The prices of illiquid securities may be more volatile than more liquid securities, and the risks associated with illiquid securities may be greater in times of financial stress.

Voya Investment Grade Credit Fund

Market: The market values of securities will fluctuate , sometimes sharply and unpredictably , based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors , political developments, and other factors. Prices of equity securities tend to rise and fall more dramatically than those of debt instruments. Additionally, legislative, regulatory, or tax policies or developments may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the Fund to achieve its investment objectives.

Market Capitalization: Stocks fall into three broad market capitalization categories: large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.

Market Disruption and Geopolitical: The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the United States. Wars, terrorism, global health crises and pandemics, and other geopolitical events that have led, and may continue to lead, to increased market volatility and may have adverse short- or long-term effects on U.S., and global economies and markets, generally. For example, the COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange suspensions and closures, declines in global financial markets, higher default rates, supply chain disruptions, and a substantial economic downturn in economies throughout the world. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. In addition, military action by Russia in Ukraine has, and may continue to, adversely affect global energy and financial markets and therefore could affect the value of the Fund’s investments, including beyond the Fund’s direct exposure to Russian issuers or nearby geographic regions. The extent and duration of the military action, sanctions, and resulting market disruptions are impossible to predict and could be substantial. A number of U.S. domestic banks and foreign (non-U.S.) banks have recently experienced financial difficulties and, in some cases, failures. There can be no certainty that the actions taken by regulators to limit the effect of those financial difficulties and failures on other banks or other financial institutions or on the U.S. or foreign (non-U.S.) economies generally will be successful. It is possible that more banks or other financial institutions will experience financial difficulties or fail, which may affect adversely other U.S. or foreign (non-U.S.) financial institutions and economies. These events as well as other changes in foreign (non-U.S.) and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Fund’s investments. Any of these occurrences could disrupt the operations of the Fund and of the Fund’s service providers.

Other Investment Companies: The main risk of investing in other investment companies, including ETFs , is the risk that the value of an investment company’s underlying investments might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the Fund’s expenses. The investment policies of the other investment companies may not be the same as those of the Fund; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Fund is typically subject. In addition, shares of ETFs may trade at a premium or discount to net asset value and are subject to secondary market trading risks. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods in times of market stress because market makers and authorized participants may step away from making a market in an ETF’s shares, which could cause a material decline in the ETF’s net asset value.

Voya Investment Grade Credit Fund

Preferred Stocks: Preferred stock generally has preference over common stock but is generally subordinate to debt instruments with respect to dividends and liquidation. Preferred stocks are subject to the risks associated with other types of equity securities, as well as greater credit or other risks than senior debt instruments. In addition, preferred stocks are subject to other risks, such as risks related to deferred and omitted distributions, limited voting rights, liquidity, interest rate, regulatory changes and special redemption rights.

Prepayment and Extension: Many types of debt instruments are subject to prepayment and extension risk. Prepayment risk is the risk that the issuer of a debt instrument will pay back the principal earlier than expected. This risk is heightened in a falling market interest rate environment. Prepayment may expose the Fund to a lower rate of return upon reinvestment of principal. Also, if a debt instrument subject to prepayment has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Extension risk is the risk that the issuer of a debt instrument will pay back the principal later than expected. This risk is heightened in a rising market interest rate environment. This may negatively affect performance, as the value of the debt instrument decreases when principal payments are made later than expected. Additionally, the Fund may be prevented from investing proceeds it would have received at a given time at the higher prevailing interest rates.

Real Estate Companies and Real Estate Investment Trusts: Investing in real estate companies and REITs may subject the Fund to risks similar to those associated with the direct ownership of real estate, including losses from casualty or condemnation, changes in local and general economic conditions, supply and demand, market interest rates, zoning laws, regulatory limitations on rents, property taxes, overbuilding, high foreclosure rates, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. In addition, REITs may also be affected by tax and regulatory requirements in that a REIT may not qualify for favorable tax treatment or regulatory exemptions. Investments in REITs are affected by the management skill of the REIT’s sponsor. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.

Repurchase Agreements: In the event that the other party to a repurchase agreement defaults on its obligations, the Fund would generally seek to sell the underlying security serving as collateral for the repurchase agreement. However, the value of collateral may be insufficient to satisfy the counterparty's obligation and/or the Fund may encounter delay and incur costs before being able to sell the security. Such a delay may involve loss of interest or a decline in price of the security, which could result in a loss. In addition, if the Fund is characterized by a court as an unsecured creditor, it would be at risk of losing some or all of the principal and interest involved in the transaction.

Securities Lending: Securities lending involves two primary risks: “ investment risk ” and “ borrower default risk. ” When lending securities, the Fund will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Fund to be more volatile. The use of leverage may increase expenses and increase the impact of the Fund’s other risks.

Sovereign Debt: Sovereign debt is issued or guaranteed by foreign (non-U.S.) government entities. Investments in sovereign debt are subject to the risk that a government entity may delay payment, restructure its debt, or refuse to pay interest or repay principal on its sovereign debt due to cash flow problems, insufficient foreign currency reserves, political considerations, social changes, the relative size of its debt position to its economy, or its failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a government entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting amounts owed on sovereign debt, such as bankruptcy proceedings, that a government does not pay.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance Information

Voya Investment Grade Credit Fund

prior to the inception date of a share class, performance information shown for such class may be based on the performance of a different class that has a longer history of operation and, in some cases, that is no longer offered by the Fund. The Class A, Class I, Class R6 and Class W performance shown for the period prior to their inception dates is the performance of Class SMA shares adjusted to reflect certain fees and expenses paid by the class with a shorter history of continuous operations, as such fees and expenses were, at the time of the adjustment, expected generally to be higher than the fees and expenses of the class on which its performance information is based. The Fund's past performance (before and after taxes) is no guarantee of future results. For the most recent performance figures, go to https://individuals.voya.com/literature or call 1-800-992-0180.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their Fund shares through tax advantaged arrangements such as 401(k) plans or individual retirement accounts (“IRAs”). In some cases the after-tax returns may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are shown for Class A shares only. After-tax returns for other classes will vary.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in securitized credit securities. The Fund will provide shareholders with at least 60 days’ prior written notice of any change in this investment policy.

Securitized credit securities include commercial mortgage-backed securities (“CMBS”), asset-backed securities (“ABS”), agency and non-agency residential mortgage-backed securities (“MBS”), and collateralized mortgage obligations. These securities may be fixed rate or adjustable rate securities. Agency MBS are issued or guaranteed by the U.S. government, its agencies or instrumentalities, which include mortgage pass-through securities representing interests in pools of mortgage loans issued or guaranteed by the Government National Mortgage Association, the Federal National Mortgage Association, or the Federal Home Loan Mortgage Corporation. The Fund may also invest in other debt instruments, which include bonds and other similar instruments issued by various U.S. and non-U.S. public or private sector entities.

The Fund may invest in interest-only, principal-only, or inverse floating rate debt. The Fund may invest in mortgage dollar rolls and may purchase or sell securities on a when-issued, delayed delivery, or forward commitment basis through the “to-be-announced” (“TBA”) market. With TBA transactions, the particular securities to be delivered are not identified at the trade date, but the delivered securities must meet specified terms and standards. The Fund may invest a portion of its assets directly in mortgage loans. The Fund may invest in securities of any maturity or duration, and the securities may have fixed, floating, or variable rates.

The Fund may invest without limit in mortgage-related high-yield (high risk) instruments rated below investment grade (commonly referred to as “junk bonds”), that, at the time of purchase, are rated below Baa3 by Moody’s Investors Service, Inc., BBB- by S&P Global Ratings, or have an equivalent rating by a Nationally Recognized Statistical Rating Organization, or, if unrated, are determined by the sub-adviser (the “Sub-Adviser”) to be of comparable quality. The Fund may invest in foreign (non-U.S.) securities, including securities of issuers located in emerging market countries, which may include non-U.S. dollar denominated foreign (non-U.S.) mortgage securities.

The Fund may invest in derivative instruments including options, futures contracts, options on futures, fixed-income swap agreements, credit default swap agreements, and currency related derivatives, including currency forwards and currency swaps, subject to applicable law. The Fund typically uses derivatives to seek to reduce exposure or other risks such as interest rate or currency risk, to substitute for taking a position in the underlying asset, and/or to enhance returns in the Fund. The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls and reverse repurchase agreements).

The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder , and under the terms of applicable no-action relief or exemptive orders granted thereunder .

The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others.

The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets.

Voya Securitized Credit Fund

Principal Risks

Credit: The Fund could lose money if the issuer or guarantor of a debt instrument in which the Fund invests , or the counterparty to a derivative contract the Fund entered into, is unable or unwilling, or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations . Asset -backed (including mortgage-backed) securities that are not issued by U.S. government agencies may have a greater risk of default because they are not guaranteed by either the U.S. government or an agency or instrumentality of the U.S. government. The credit quality of typical asset-backed securities depends primarily on the credit quality of the underlying assets and the structural support (if any) provided to the securities.

Foreign (Non-U.S.) Investments/Developing and Emerging Markets: Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due, in part, to: smaller markets; differing reporting, accounting, auditing , and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions (or the threat of new or modified sanctions) or other measures by the U.S. or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and

Voya Securitized Credit Fund

conditions or events in one market, country, or region may adversely impact investments or issuers in another market, country, or region. Foreign (non-U.S.) investment risks may be greater in developing and emerging markets than in developed markets.

Interest in Loans: The value and the income streams of interests in loans (including participation interests in lease financings and assignments in secured variable or floating rate loans) will decline if borrowers delay payments or fail to pay altogether. A significant rise in market interest rates could increase this risk. Although loans may be fully collateralized when purchased, such collateral may become illiquid or decline in value.

Voya Securitized Credit Fund

When-Issued, Delayed Delivery , and Forward Commitment Transactions : When - issued , delayed delivery , and forward commitment transactions involve the risk that the security the Fund buys will lose value prior to its delivery. These transactions may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Fund to be more volatile. The use of leverage may increase expenses and increase the impact of the Fund’s other risks. There also is the risk that the security will not be issued or that the other party will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance Information

The following information is intended to help you understand the risks of investing in the Fund. The following bar chart shows the changes in the Fund's performance from year to year, and the table compares the Fund's performance to the performance of a broad-based securities market index/indices with investment characteristics similar to those of the Fund for the same period. The Fund's performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund's Class A shares. Performance for other share classes would differ to the extent they have differences in their fees and expenses. Not all share classes of the Fund have the same inception date. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of a different class that has a longer history of operation and, in some cases, that is no longer offered by the Fund. The Class A, Class I and Class R6 performance shown for the period prior to their inception dates is the performance of Class P shares adjusted to reflect certain fees and expenses paid by the class with a shorter history of continuous operations, as such fees and expenses were, at the time of the adjustment, expected generally to be higher than the fees and expenses of the class on which its performance information is based. The Fund's past performance (before and after taxes) is no guarantee of future results. For the most recent performance figures, go to https://individuals.voya.com/literature or call 1-800-992-0180.

KEY FUND INFORMATION

This Prospectus contains information about each Fund and is designed to provide you with important information to help you with your investment decisions. Please read it carefully and keep it for future reference.

Each Fund's Statement of Additional Information (the “SAI”) is incorporated by reference into (legally made a part of) this Prospectus. It identifies investment restrictions, more detailed risk descriptions, a description of how the bond rating system works, and other information that may be helpful to you in your decision to invest. You may obtain a copy, without charge, from each Fund.

Neither this Prospectus, nor the related SAI, nor other communications to shareholders, such as proxy statements, is intended, or should be read, to be or give rise to an agreement or contract between Voya Separate Portfolios Trust (the “Trust”), the Board of Trustees (the “Board”), or each Fund and any investor, or to give rise to any rights to any shareholder or other person other than any rights under federal or state law.

Other Voya mutual funds may also be offered to the public that have similar names, investment objectives, and principal investment strategies as those of a Fund. You should be aware that each Fund is likely to differ from these other Voya mutual funds in size and cash flow pattern, as well as other factors. Accordingly, the performance of each Fund can be expected to vary from those of other Voya mutual funds.

Other mutual funds and/or funds-of-funds may invest in a Fund. So long as a Fund accepts investments by other investment companies, it will not purchase securities of other investment companies, except to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder , and under the terms of applicable no-action relief or exemptive orders granted thereunder (the “1940 Act”).

Each Fund is a series of the Trust, a Delaware statutory trust. Each Fund is managed by Voya Investments, LLC (“Voya Investments” or the “Investment Adviser”).

Fund shares may be classified into different classes of shares. The classes of shares of a Fund would be substantially the same except for different expenses, certain related rights, and certain shareholder services. All share classes of a Fund have a common investment objective and investment portfolio.

Fundamental Investment Policies

Fundamental investment policies contained in the SAI may not be changed without shareholder approval. Other policies and investment strategies may be changed without a shareholder vote.

Non-Fundamental Investment Policies

Each Fund has adopted a non-fundamental investment policy to invest the Fund's assets in securities that are consistent with the Fund's name. For more information about each Fund's non-fundamental investment policies, please consult the SAI.

Fund Diversification

Each Fund is diversified, as such term is defined in the 1940 Act . A diversified fund may not, as to 75% of its total assets, invest more than 5% of its total assets in any one issuer and may not purchase more than 10% of the outstanding voting securities of any one issuer (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities, or other investment companies). A non-diversified fund is not limited by the 1940 Act in the percentage of its assets that it may invest in the obligations of a single issuer.

Investor Diversification

Although each Fund is designed to serve as a component of a diversified investment portfolio of securities, no single mutual fund can provide an appropriate investment program for all investors. You should evaluate a Fund in the context of your personal financial situation, investment objectives, and other investments.

Temporary Defensive Strategies

When the Investment Adviser or the sub-adviser (the “Sub-Adviser”) anticipates unusual market, economic, political, or other conditions, a Fund may temporarily depart from its principal investment strategies as a defensive measure. In such circumstances, a Fund may invest in securities believed to present less risk, such as cash, cash equivalents, money market fund shares and other money market instruments, debt instruments that are high quality or higher

KEY FUND INFORMATION (continued)

quality than normal, more liquid securities, or others. While a Fund invests defensively, it may not achieve its investment objective. A Fund's defensive investment position may not be effective in protecting its value. It is impossible to predict accurately how long such alternative strategies may be utilized.

Percentage and Rating Limitations

The percentage and rating limitations on Fund investments listed in this Prospectus apply at the time of investment.

Investment Not Guaranteed

Please note your investment is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other government agency.

Shareholder Reports

Each Fund's fiscal year ends March 31. Copies of each Fund's annual and semi-annual shareholder reports are no longer sent by mail or e-mail, unless you specifically request copies of the reports. Instead, the reports are available on the Voya funds’ website (https://individuals.voya.com/literature), and you will be notified by mail each time a report is posted and provided with a website link to access the report. You may elect to receive shareholder reports and other communications from a fund electronically anytime by contacting your financial intermediary (such as a broker-dealer or bank) or, if you are a direct investor, by calling 1-800-992-0180 or by sending an e-mail request to [email protected].

MORE INFORMATION ABOUT THE FUNDS

Additional Information About the Investment Objective

Each Fund's investment objective is non-fundamental and may be changed by a vote of the Trustees (the “ Board ” ) , without shareholder approval. A Fund will provide 60 days' prior written notice of any change in a non-fundamental investment objective. There is no guarantee a Fund will achieve its investment objective.

Additional Information About Principal Investment Strategies

For a complete description of each Fund's principal investment strategies, please see the Fund's summary prospectus or the Fund’s summary section in this Prospectus.

Additional Information About the Principal Risks

All mutual funds involve risk—some more than others—and there is always the chance that you could lose money or not earn as much as you hope. Each Fund's risk profile is largely a factor of the principal securities in which it invests and investment techniques that it uses. Below is a discussion of the principal risks associated with certain of the types of securities in which a Fund may invest and certain of the investment practices that a Fund may use. The principal risks are presented in alphabetical order to facilitate readability, and their order does not imply that the realization of one risk is more likely to occur or have a greater adverse impact than another risk. For more information about these and other types of securities and investment techniques that may be used by each Fund, see the SAI.

Many of the investment techniques and strategies discussed in this Prospectus and in the SAI are discretionary, which means that the Investment Adviser or Sub-Adviser can decide whether to use them. A Fund may invest in these securities or use these techniques as part of the Fund's principal investment strategies. However, the Investment Adviser or Sub-Adviser may also use these investment techniques or make investments in securities that are not a part of a Fund's principal investment strategies.

The discussions below expand on the risks included in each Fund's summary section of the Prospectus. Please see the SAI for a further discussion of the principal and other investment strategies employed by each Fund.

Bank Instruments: Bank instruments include certificates of deposit, fixed time deposits, bankers’ acceptances, and other debt and deposit-type obligations issued by banks. Changes in economic, regulatory, or political conditions, or other events that affect the banking industry may have an adverse effect on bank instruments or banking institutions that serve as counterparties in transactions with a Fund. In the event of a bank insolvency or failure, a Fund may be considered a general creditor of the bank, and it might lose some or all of the funds deposited with the bank. Even where it is recognized that a bank might be in danger of insolvency or failure, a Fund might not be able to withdraw or transfer its money from the bank in time to avoid any adverse effects of the insolvency or failure.

Collateralized Loan Obligations and Other Collateralized Obligations: A CLO is an obligation of a trust or other special purpose vehicle typically collateralized by a pool of loans, which may include senior secured and unsecured loans and subordinate corporate loans, including loans that may be rated below investment grade, or equivalent unrated loans. CLOs may incur management fees and administration fees. The risks of investing in a CLO depend largely on the type of the collateral held in the CLO portfolio and the tranche of securities in which a Fund, and can generally be summarized as a combination of economic risks of the underlying loans combined with the risks associated with the CLO structure governing the priority of payments, and include interest rate risk, credit risk, liquidity risk, prepayment and extension risk, and the risk of default of the underlying asset, among others .

MORE INFORMATION ABOUT THE FUNDS (continued)

•

Convertible Securities: Convertible securities are securities that are convertible into or exercisable for common stocks at a stated price or rate. Convertible securities are subject to the usual risks associated with debt instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk. The value of a convertible security will normally fluctuate in some proportion to changes in the value of the underlying stock because of the conversion or exercise feature. However, the value of a convertible security may not increase or decrease as rapidly as the underlying stock. Convertible securities may be rated below investment grade and therefore may be subject to greater levels of credit risk and liquidity risk. In the event the issuer of a convertible security is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, a Fund could lose money; such events may also have the effect of reducing a Fund's distributable income. There is a risk that a Fund may convert a convertible security at an inopportune time, which may decrease the Fund’s returns.

Covenant-Lite Loans: Loans in which a Fund may invest or to which a Fund may gain exposure indirectly through its investments in collateralized debt obligations, CLOs or other types of structured securities may be considered “covenant-lite” loans. Covenant-lite refers to loans which do not incorporate traditional performance-based financial maintenance covenants. Covenant-lite does not refer to a loan’s seniority in a borrower’s capital structure nor to a lack of the benefit from a legal pledge of the borrower’s assets and does not necessarily correlate to the overall credit quality of the borrower. Covenant-lite loans generally do not include terms which allow a lender to take action based on a borrower’s performance relative to its covenants. Such actions may include the ability to renegotiate and/or re-set the credit spread on the loan with a borrower, and even to declare a default or force the borrower into bankruptcy restructuring if certain criteria are breached. Covenant-lite loans typically still provide lenders with other covenants that restrict a borrower from incurring additional debt or engaging in certain actions. Such covenants can only be breached by an affirmative action of the borrower, rather than by a deterioration in the borrower’s financial condition. Accordingly, a Fund may have fewer rights against a borrower when it invests in, or has exposure to, covenant-lite loans and, accordingly, may have a greater risk of loss on such investments as compared to investments in, or exposure to, loans with additional or more conventional covenants.

Credit: A Fund could lose money if the issuer or guarantor of a debt instrument in which the Fund invests , or the counterparty to a derivative contract the Fund entered into, is unable or unwilling , or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations . Asset-backed (including mortgage-backed) securities that are not issued by U.S. government agencies may have a greater risk of default because they are not guaranteed by either the U.S. government or an agency or instrumentality of the U.S. government. The credit quality of typical asset-backed securities depends primarily on the credit quality of the underlying assets and the structural support (if any) provided to the securities.

Credit Default Swaps: A Fund may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a credit default swap is generally obligated to pay the seller an upfront or a periodic stream of payments over the term of the contract until a credit event, such as a default , on a reference obligation has occurred . If a credit event occurs, the seller generally must pay the buyer the “ par value ” ( full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount if the swap is cash settled. As a seller of a credit default swap, a Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, valuation, liquidity, and leveraging risks and the risk that the swap may not correlate with its reference obligation as expected. Certain standardized credit default swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that it will achieve that result, and, in the meantime, central clearing and related requirements expose a Fund to new kinds of costs and risks. In addition, credit default swaps expose a Fund to the risk of improper valuation.

Currency: To the extent that a Fund invests directly or indirectly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged by the Fund through foreign currency exchange transactions. Currency rates may fluctuate significantly over short periods of time. Currency rates may be affected by changes in market interest rates, intervention (or the failure to intervene) by the U.S. or foreign (non-U.S.) governments, central banks or supranational entities such as the International Monetary Fund, by the imposition of currency controls, or other political or economic developments in the U.S. or abroad.

Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying asset, reference rate, or index credit risk with respect to the counterparty, risk of loss due to changes in market interest rates, liquidity risk, valuation risk, and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by a Fund. Therefore, the purchase of certain derivatives may have an economic leveraging effect on a Fund and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so a Fund may not realize the intended benefits. When used for hedging purposes, the change in value of a derivative may not correlate as expected with the asset, reference rate, or index being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment. Generally, derivatives are sophisticated financial instruments whose performance is derived, at least in part, from the performance of an underlying asset, reference rate, or index. Derivatives include, among other things, swap agreements, options, forward foreign currency exchange contracts, and futures. Certain derivatives in which a Fund may invest may be negotiated over-the-counter with a single counterparty and as a result are subject to credit risks related to the counterparty’s ability or willingness to perform its obligations; any deterioration in the counterparty’s creditworthiness could adversely affect the value of the derivative. In addition, derivatives and their underlying instruments may experience periods of illiquidity which could cause a Fund to hold a position it might otherwise sell, or to sell a position it otherwise might hold at an inopportune time or price. A manager might imperfectly judge the direction of the market. For instance, if a derivative is used as a hedge to offset investment risk in another security, the hedge might not correlate to the market’s movements and may have unexpected or undesired results such as a loss or a reduction in gains. The U.S. government has enacted legislation that provides for new regulation of the derivatives market, including clearing, margin, reporting, and registration requirements. The European Union (and other countries outside of the European Union, including the United Kingdom) has implemented similar requirements, which may affect a Fund when it enters into a derivatives transaction with a counterparty organized in that country or otherwise subject to that country's derivatives regulations. Because these requirements are relatively new and evolving (and some of the rules are not yet final), their ultimate impact remains unclear. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that it will achieve that result, and, in the meantime, central clearing and related requirements expose a Fund to new kinds of costs and risks.

Environmental, Social, and Governance (Fixed Income): The Sub-Adviser’s consideration of ESG factors in selecting investments for a Fund is based on information that is not standardized, some of which can be qualitative and subjective by nature . The Sub-Adviser’s assessment of ESG factors in respect of obligations of an issuer may rely on third party data that might be incorrect or based on incomplete or inaccurate information. There is no minimum percentage of a Fund’s assets that will be invested in obligations of issuers that the Sub-Adviser views favorably in light of ESG factors, and the Sub-Adviser may choose not to invest in obligations of issuers that compare favorably to obligations of other issuers on the basis of ESG factors. It is possible that a Fund will have less exposure to obligations of certain issuers due to the Sub-Adviser’s assessment of ESG factors than other comparable mutual funds. There can be no assurance that an investment selected by the Sub-Adviser, which includes its consideration of ESG factors, will provide more favorable investment performance than another potential investment, and such an investment may, in fact, underperform other potential investments.

Foreign (Non-U.S.) Investments/Developing and Emerging Markets: To the extent a Fund invests in securities of issuers in markets outside the U.S., its share price may be more volatile than if it invested in securities of issuers in the U.S. market due to, among other things, the following factors: comparatively unstable political, social and economic conditions and limited or ineffectual judicial systems; wars; comparatively small market sizes, making securities less liquid and securities prices more sensitive to the movements of large investors and more vulnerable to manipulation; governmental policies or actions, such as high taxes, restrictions on currency movements, replacement of currency,

potential for default on sovereign debt, trade or diplomatic disputes, which may include the imposition of economic sanctions (or the threat of new or modified sanctions) or other measures by the U.S. or other governments and supranational organizations, creation of monopolies, and seizure of private property through confiscatory taxation and expropriation or nationalization of company assets; incomplete, outdated, or unreliable information about securities issuers due to less stringent market regulation and accounting, auditing and financial reporting standards and practices; comparatively undeveloped markets and weak banking and financial systems; market inefficiencies, such as higher transaction costs, and administrative difficulties, such as delays in processing transactions; and fluctuations in foreign currency exchange rates, which could reduce gains or widen losses.

Economic or other sanctions imposed on a foreign (non-U.S.) country or issuer by the U.S. or on the U.S. by a foreign (non-U.S.) country, could impair a Fund's ability to buy, sell, hold, receive, deliver, or otherwise transact in certain securities. In addition, foreign withholding or other taxes could reduce the income available to distribute to shareholders, and special U.S. tax considerations could apply to foreign (non-U.S.) investments. Depositary receipts are subject to risks of foreign (non-U.S.) investments and might not always track the price of the underlying foreign (non-U.S.) security. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country, or region may adversely impact investments or issuers in another market, country, or region.

In March 2017, the United Kingdom (“UK”) formally notified the European Council of its intention to leave the EU and on January 31, 2020 withdrew from the EU (commonly known as “Brexit”). On December 30, 2020, the UK voted in favor of the UK-EU Trade and Cooperation Agreement. The agreement governs the new relationship between the UK and the EU with respect to trading goods and services but critical aspects of the relationship remain unresolved and subject to further negotiation and agreement. Brexit has resulted in volatility in European and global markets and could have negative long-term impacts on financial markets in the UK and throughout Europe. There is considerable uncertainty about the potential consequences of Brexit and how the financial markets will react. As this process unfolds, markets may be further disrupted. Given the size and importance of the UK’s economy, uncertainty about its legal, political, and economic relationship with the remaining member states of the EU may continue to be a source of instability.

Foreign (non-U.S.) investment risks may be greater in developing and emerging markets than in developed markets, for such reasons as social or political unrest, heavy economic dependence on international aid, agriculture or exports (particularly commodities), undeveloped or overburdened infrastructures and legal systems, vulnerability to natural disasters, significant and unpredictable government intervention in markets or the economy, volatile currency exchange rates, currency devaluations, runaway inflation, business practices that depart from norms for developed countries, and generally less developed or liquid markets. The Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, is unable to inspect audit work papers in certain foreign (non-U.S.) countries. Investors in foreign (non-U.S.) countries often have limited rights and few practical remedies to pursue shareholder claims, including class actions or fraud claims, and the ability of the SEC, the U.S. Department of Justice and other authorities to bring and enforce actions against foreign (non-U.S.) issuers or persons is limited. Settlement and asset custody practices for transactions in emerging markets may differ from those in developed markets. Such differences may include possible delays in settlement and certain settlement practices, such as delivery of securities prior to receipt of payment, which increases the likelihood of a “failed settlement.” Failed settlements can result in losses.

In addition, the Holding Foreign Companies Accountable Act (the “HFCAA”) could cause securities of a foreign (non-U.S.) company, including American Depositary Receipts, to be delisted from U.S. stock exchanges if the company does not allow the U.S. government to oversee the auditing of its financial information. Although the requirements of the HFCAA apply to securities of all foreign (non-U.S.) issuers, the SEC has thus far limited its enforcement efforts to securities of Chinese companies. If securities are delisted, a Fund’s ability to transact in such securities will be impaired, and the liquidity and market price of the securities may decline. A Fund may also need to seek other markets in which to transact in such securities, which could increase the Fund’s costs.

Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other debt instruments ; conversely, values generally rise as market interest rates fall. Interest rate risk is generally greater for debt instruments than floating-rate instruments. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is to changes in market interest rates. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. As of the date of this Prospectus, the U.S. has been experiencing a rising market interest rate environment, which may increase a Fund’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose debt and related markets to heightened volatility. To the extent that a Fund invests in debt instruments, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause a Fund to liquidate portfolio positions when it may not be advantageous to do so and may lower returns. If dealer capacity in debt markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in the debt markets. Further, recent and potential future changes in government policy may affect interest rates. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose debt and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose debt and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact a Fund’s operations and return potential.

Investment Model: The Sub-Adviser ’s proprietary investment model may not adequately take into account existing or unforeseen market factors or the interplay between such factors, and there is no guarantee that the use of a proprietary investment model will result in effective investment decisions for a Fund. Proprietary investment models used by the Sub-Adviser to evaluate securities or securities markets are based on the Sub-Adviser’s understanding of the interplay of market factors and do not assure successful investment. The markets, or the price of individual securities, may be affected by factors not foreseen in the construction of the investment models. Funds that are actively managed, in whole or in part, according to a quantitative investment model (or that utilize artificial intelligence) can perform differently from the market, based on the investment model and the factors used in the analysis, the weight placed on each factor, and changes from the factors’ historical trends. Mistakes in the construction and implementation of the investment models (including, for example, data problems and/or software issues) may create errors or limitations that might go undetected or are discovered only after the errors or limitations have negatively impacted performance.

Liquidity: If a security is illiquid, a Fund might be unable to sell the security at a time when the Fund’s manager might wish to sell, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing a Fund to the risk that the prices at which it sells illiquid securities will be less than the prices at which they were valued when held by a Fund, which could cause the Fund to lose money. The prices of illiquid securities may be more volatile than more liquid securities, and the risks associated with illiquid securities may be greater in times of financial stress.

Market: The market values of securities will fluctuate , sometimes sharply and unpredictably , based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors , political developments, and other factors . Prices of equity securities tend to rise and fall more dramatically than those of debt instruments. Additionally, legislative, regulatory, or tax policies or developments may adversely impact the investment techniques available to a manager, add to costs and impair the ability of a Fund to achieve its investment objectives.

product lines, more limited financial resources, smaller management groups, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.

Market Disruption and Geopolitical: A Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the United States. Wars, terrorism, global health crises and pandemics, and other geopolitical events that have led, and may continue to lead, to increased market volatility and may have adverse short- or long-term effects on U.S., and global economies and markets, generally. For example, the COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange suspensions and closures, declines in global financial markets, higher default rates, supply chain disruptions, and a substantial economic downturn in economies throughout the world. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. In addition, military action by Russia in Ukraine has, and may continue to, adversely affect global energy and financial markets and therefore could affect the value of a Fund’s investments, including beyond the Fund’s direct exposure to Russian issuers or nearby geographic regions. The extent and duration of the military action, sanctions, and resulting market disruptions are impossible to predict and could be substantial. A number of U.S. domestic banks and foreign (non-U.S.) banks have recently experienced financial difficulties and, in some cases, failures. There can be no certainty that the actions taken by regulators to limit the effect of those financial difficulties and failures on other banks or other financial institutions or on the U.S. or foreign (non-U.S.) economies generally will be successful. It is possible that more banks or other financial institutions will experience financial difficulties or fail, which may affect adversely other U.S. or foreign (non-U.S.) financial institutions and economies. These events as well as other changes in foreign (non-U.S.) and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of a Fund’s investments. Any of these occurrences could disrupt the operations of a Fund and of the Fund’s service providers.

Mortgage- and/or Asset-Backed Securities: Defaults on, or low credit quality or liquidity of , the underlying assets of the asset-backed (including mortgage-backed) securities may impair the value of these securities and result in losses. There may be limitations on the enforceability of any security interest or collateral granted with respect to those underlying assets, and the value of collateral may not satisfy the obligation upon default. These securities also present a higher degree of prepayment and extension risk and interest rate risk than do other types of debt instruments. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain asset-backed securities. The value of longer-term securities generally changes more in response to changes in market interest rates than shorter-term securities.

These securities may be affected significantly by government regulation, market interest rates, market perception of the creditworthiness of an issuer servicer, and loan-to-value ratio of the underlying assets. During an economic downturn, the mortgages, commercial or consumer loans, trade or credit card receivables, installment purchase obligations, leases, or other debt obligations underlying an asset-backed security may experience an increase in defaults as borrowers experience difficulties in repaying their loans which may cause the valuation of such securities to be more volatile and may reduce the value of such securities. These risks are particularly heightened for investments in asset-backed securities that contain sub-prime loans, which are loans made to borrowers with weakened credit histories and often have higher default rates.

Municipal Obligations: The municipal securities market is volatile and can be affected significantly by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities. Among other risks, investments in municipal securities are subject to the risk that an issuer may delay payment, restructure its debt, or refuse to pay interest or repay principal on its debt. Municipal revenue obligations may be backed by the revenues generated from a specific project or facility and include industrial development bonds and private activity bonds. Private activity and industrial development bonds are dependent on the ability of the facility’s user to meet its financial obligations and the value of any real or personal property pledged as security for such payment. Many municipal securities are issued to finance projects relating to education, health care, transportation, and utilities. Conditions in those sectors may affect the overall municipal securities market. In addition, municipal securities backed by current or anticipated revenues from a specific project or specific asset may be adversely affected by the discontinuance of the taxation supporting the project or asset or the inability to collect revenues from the project or asset. If an issuer of a municipal

security does not comply with applicable tax requirements for tax-exempt status, interest from the security may become taxable, and the security could decline in value.

ETFs are exchange-traded investment companies that are, in many cases, designed to provide investment results corresponding to an index. Additional risks of investments in ETFs include that: (i) an active trading market for an ETF’s shares may not develop or be maintained; or (ii) trading may be halted if the listing exchanges’ officials deem such action appropriate, the shares are delisted from an exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts trading of an ETF’s shares. Other investment companies include Holding Company Depositary Receipts (“HOLDRs”). Because HOLDRs concentrate in the stocks of a particular industry, trends in that industry may have a dramatic impact on their value. In addition, shares of ETFs may trade at a premium or discount to net asset value and are subject to secondary market trading risks. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods in times of market stress because market makers and authorized participants may step away from making a market in an ETF’s shares, which could cause a material decline in the ETF’s net asset value.

Preferred Stocks: Preferred stocks represent an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other securities such as common stocks, dividends, and a fixed share of the proceeds resulting from a liquidation of the company. Some preferred stocks also entitle their holders to receive additional liquidation proceeds on the same basis as holders of a company’s common stock, and thus also represent an ownership interest in that company.

Preferred stock may pay fixed or adjustable rates of return. Preferred stock is subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company’s preferred stock generally pays dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred stock will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects.

Preferred stock of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies.

Preferred stock includes certain hybrid securities and other types of preferred stock with different features from those of traditional preferred stock described above. Preferred stocks that are hybrid securities possess various features of both debt and traditional preferred stock and as such, they may constitute senior debt, junior debt, or preferred shares in an issuer’s capital structure. Therefore, unlike traditional preferred stock, hybrid securities may not be subordinate to a company’s debt instruments.

Preferred stock may include features permitting or requiring the issuer to defer or omit distributions. Among other things, such deferral or omission may result in adverse tax consequences for a Fund. Preferred stock generally does not have voting rights with respect to the issuer unless dividends have been in arrears for certain specified periods of time. Preferred stock may be less liquid than other securities. As a result, preferred stock is subject to the risk that they may be unable to be sold at the time desired by a Fund or at prices approximating the values at which the Fund is carrying the stock on its books. In addition, over longer periods of time, certain types of preferred stock may become more scarce or less liquid as a result of legislative changes. Such events may negatively affect the prices of stock held by a Fund, which may result in losses to the Fund. In addition, an issuer of preferred stock may redeem the stock prior to a specified date, which may occur due to changes in tax or securities laws or corporate actions. A redemption by the issuer may negatively impact the return of the preferred stock.

of principal. Also, if a debt instrument subject to prepayment has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Extension risk is the risk that the issuer of a debt instrument will pay back the principal later than expected. This risk is heightened in a rising market interest rate environment. This may negatively affect performance, as the value of the debt instrument decreases when principal payments are made later than expected. Additionally, a Fund may be prevented from investing proceeds it would have received at a given time at the higher prevailing interest rates.

Real Estate Companies and Real Estate Investment Trusts: Investing in real estate companies and REITs may subject a Fund to risks similar to those associated with the direct ownership of real estate, including losses from casualty or condemnation, changes in local and general economic conditions, supply and demand, market interest rates, zoning laws, regulatory limitations on rents, property taxes, overbuilding, high foreclosure rates, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. Some REITs may invest in a limited number of properties, in a narrow geographic area or in a single property type, which increases the risk that a Fund could be unfavorably affected by the poor performance of a single investment or investment type. These companies are also sensitive to factors such as changes in real estate values and property taxes, market interest rates, cash flow of underlying real estate assets, supply and demand, and the management skill and creditworthiness of the issuer. Borrowers could default on or sell investments the REIT holds, which could reduce the cash flow needed to make distributions to investors. In addition, REITs may also be affected by tax and regulatory requirements in that a REIT may not qualify for favorable tax treatment or regulatory exemptions. Investments in REITs are affected by the management skill of the REIT’s sponsor. A Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.

Repurchase Agreements: In the event that the other party to a repurchase agreement defaults on its obligations, a Fund would generally seek to sell the underlying security serving as collateral for the repurchase agreement. However, the value of collateral may be insufficient to satisfy the counterparty's obligation and/or a Fund may encounter delay and incur costs before being able to sell the security. Such a delay may involve loss of interest or a decline in price of the security, which could result in a loss. In addition, if a Fund is characterized by a court as an unsecured creditor, it would be at risk of losing some or all of the principal and interest involved in the transaction.

Securities Lending: Securities lending involves two primary risks: “ investment risk ” and “ borrower default risk. ” When lending securities, a Fund will receive cash or U.S. government securities as collateral. Investment risk is the risk that a Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that a Fund will lose money due to the failure of a borrower to return a borrowed security. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing a Fund to be more volatile. The use of leverage may increase expenses and increase the impact of a Fund’s other risks.

A Fund seeks to minimize investment risk by limiting the investment of cash collateral to high-quality instruments of short maturity. In the event of a borrower default, a Fund will be protected to the extent the Fund is able to exercise its rights in the collateral promptly and the value of such collateral is sufficient to purchase replacement securities. A Fund is protected by its securities lending agent, which has agreed to indemnify the Fund from losses resulting from borrower default.

U.S. Government Securities and Obligations: U.S. government securities are obligations of, or guaranteed by, the U.S. government, its agencies, or government-sponsored enterprises. U.S. government securities are subject to market risk and interest rate risk, and may be subject to varying degrees of credit risk. Some U.S. government securities are backed by the full faith and credit of the U.S. government and are guaranteed as to both principal and interest by the U.S. Treasury. These include direct obligations of the U.S. Treasury such as U.S. Treasury notes, bills, and bonds, as well as indirect obligations including certain securities of the Government National Mortgage Association, the Small

MORE INFORMATION ABOUT THE FUNDS (continued)

Business Administration, and the Farmers Home Administration, among others. Other U.S. government securities are not direct obligations of the U.S. Treasury, but rather are backed by the ability to borrow directly from the U.S. Treasury, including certain securities of the Federal Financing Bank, the Federal Home Loan Bank, and the U.S. Postal Service. Other U.S. government securities are backed solely by the credit of the agency or instrumentality itself and are neither guaranteed nor insured by the U.S. government and, therefore, involve greater risk. These include securities issued by the Federal Home Loan Bank, the Federal Home Loan Mortgage Corporation, and the Federal Farm Credit Bank, among others. Consequently, the investor must look principally to the agency issuing or guaranteeing the obligation for ultimate repayment. No assurance can be given that the U.S. government would provide financial support to such agencies if it is not obligated to do so by law. The impact of greater governmental scrutiny into the operations of certain agencies and government-sponsored enterprises may adversely affect the value of securities issued by these entities. U.S. government securities may be subject to price declines due to changing market interest rates. From time to time, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could increase the risk that the U.S. government may default on payments on certain U.S. government securities, cause the credit rating of the U.S. government to be downgraded, increase volatility in the stock and bond markets, result in higher interest rates, reduce prices of U.S. Treasury securities, and/or increase the costs of various kinds of debt. If a U.S. government-sponsored entity is negatively impacted by legislative or regulatory action (or lack thereof), is unable to meet its obligations, or its creditworthiness declines, the performance of a Fund that holds securities of the entity will be adversely impacted.

When-Issued, Delayed Delivery , and Forward Commitment Transactions : When - issued , delayed delivery , and forward commitment transactions involve the risk that the security a Fund buys will lose value prior to its delivery. These transactions may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing a Fund to be more volatile. The use of leverage may increase expenses and increase the impact of a Fund’s other risks. There also is the risk that the security will not be issued or that the other party will not meet its obligation. If this occurs, a Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.

Further Information About Principal Risks

The following provides additional information about certain aspects of the principal risks described above.

Counterparty: The entity with which a Fund conducts portfolio-related business (such as trading or securities lending), or that underwrites, distributes or guarantees investments or agreements that the Fund owns or is otherwise exposed to, may refuse or may become unable to honor its obligations under the terms of a transaction or agreement. As a result, the Fund may sustain losses and be less likely to achieve its investment objective. These risks may be greater when engaging in over-the-counter transactions or when a Fund conducts business with a limited number of counterparties.

Duration: One measure of risk for debt instruments is duration. Duration measures the sensitivity of a bond’s price to market interest rate movements and is one of the tools used by a portfolio manager in selecting debt instruments. Duration measures the average life of a bond on a present value basis by incorporating into one measure a bond’s yield, coupons, final maturity and call features. As a point of reference, the duration of a non-callable 7% coupon bond with a remaining maturity of 5 years is approximately 4.5 years and the duration of a non-callable 7% coupon bond with a remaining maturity of 10 years is approximately 8 years. Material changes in market interest rates may impact the duration calculation. For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%.

Inflation: Inflation risk is the risk that the value of assets or income from a Fund's investments will be worth less in the future as inflation decreases the value of payments at future dates. As inflation increases, the value of a Fund’s portfolio could decline. Inflation rates may change frequently and drastically as a result of various factors and a Fund's investments may not keep pace with inflation, which may result in losses to the Fund’s investors or adversely affect the value of shareholders' investments in the Fund. Inflation has recently increased, and it cannot be predicted whether it may decline.

Investment by Other Funds: Certain funds-of-funds, including some Voya funds, may invest in a Fund. If investments by these other funds result in large inflows or outflows of cash from a Fund, a Fund could be required to sell securities or invest cash at times, or in ways, that could, among other things, negatively impact its performance, speed the realization of capital gains, increase its portfolio turnover, affect the liquidity of its portfolio, or increase transaction

MORE INFORMATION ABOUT THE FUNDS (continued)

costs. The manager will monitor transactions by such funds-of-funds and will attempt to minimize any adverse effects these transactions may have on a Fund. If shares of a Fund are purchased by another fund in reliance on Section 12(d)(1)(G) of the 1940 Act or Rule 12d1-4 thereunder and the Fund purchases shares of other investment companies in reliance on Rule 12d1-4, the Fund will not be able to make new investments in other funds, including private funds, if, as a result of such investment, more than 10% of the Fund’s assets would be invested in other funds or private funds, subject to certain exceptions.

Leverage: Certain transactions and investment strategies may give rise to leverage. Such transactions and investment strategies include, but are not limited to: borrowing, dollar rolls, reverse repurchase agreements, loans of portfolio securities, short sales, and the use of when-issued, delayed delivery or forward commitment transactions. The use of certain derivatives may also increase leveraging risk and, in some cases, adverse changes in the value or level of a derivative’s underlying asset, rate, or index may result in potentially unlimited losses. The use of leverage may exaggerate any increase or decrease in the net asset value, causing a Fund to be more volatile than if the Fund had not been leveraged. The use of leverage may increase expenses and increase the impact of a Fund’s other risks. The use of leverage may cause a Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet regulatory requirements resulting in increased volatility of returns.

Manager: A Fund is subject to manager risk because it is an actively managed investment portfolio. The Investment Adviser, the Sub-Adviser or each individual portfolio manager will make judgments and apply investment techniques and risk analyses in making investment decisions, but there can be no guarantee that these decisions will produce the desired results. A Fund’s portfolio may fail to produce the intended results, and a Fund’s portfolio may underperform other comparable funds because of portfolio management decisions related to, among other things, the selection of investments, portfolio construction, risk assessments, and/or the outlook on market trends and opportunities.

Operational: A Fund, its service providers, and other market participants increasingly depend on complex information technology and communications systems to conduct business functions. These systems are subject to a number of different threats or risks that could adversely affect a Fund and its shareholders, despite the efforts of a Fund and its service providers to adopt technologies, processes, and practices intended to mitigate these risks. Cyber-attacks, disruptions, or failures that affect a Fund’s service providers, counterparties, market participants, or issuers of securities held by a Fund may adversely affect a Fund and its shareholders, including by causing losses or impairing the Fund’s operations. Information relating to a Fund’s investments has been and will in the future be delivered electronically, which can give rise to a number of risks, including, but not limited to, the risks that such communications may not be secure and may contain computer viruses or other defects, may not be accurately replicated on other systems, or may be intercepted, deleted or interfered with, without the knowledge of the sender or the intended recipient.

Management Fee

The Investment Adviser receives an annual fee for its services to each Fund. The fee is payable in monthly installments based on the average daily net assets of each Fund.

The Investment Adviser is responsible for all of its own costs, including costs of the personnel required to carry out its duties.

The following table shows the aggregate annual management fee paid by each Fund for the most recent fiscal year as a percentage of the Fund’s average daily net assets.

	Management Fees
Voya Investment Grade Credit Fund	0.50%
Voya Securitized Credit Fund	0.60%

For information regarding the basis for the Board’s approval of the investment advisory and investment sub-advisory relationships, please refer to the Funds' annual shareholder report, which covers the one-year period ended March 31, 2023.

The Sub-Adviser and Portfolio Managers

The Investment Adviser has engaged a sub-adviser to provide the day-to-day management of each Fund's portfolio. The Sub-Adviser is an affiliate of the Investment Adviser.

The Investment Adviser acts as a “manager-of-managers” for each Fund. The Investment Adviser has ultimate responsibility, subject to the oversight of each Fund’s Board, to oversee any sub-advisers and to recommend the hiring, termination, or replacement of sub-advisers. Each Fund and the Investment Adviser have received exemptive relief from the SEC which permits the Investment Adviser, with the approval of the Board but without obtaining shareholder approval, to enter into or materially amend a sub-advisory agreement with sub-advisers that are not affiliated with the Investment Adviser (“non-affiliated sub-advisers”) as well as sub-advisers that are indirect or direct, wholly-owned subsidiaries of the Investment Adviser or of another company that indirectly or directly wholly owns the Investment Adviser (“wholly-owned sub-advisers”).

Consistent with the “manager-of-managers” structure, the Investment Adviser delegates to the Sub-Adviser(s) of each Fund the responsibility for day-to-day investment management, subject to the Investment Adviser’s oversight. The Investment Adviser is responsible for, among other things, monitoring the investment program and performance of the Sub-Adviser(s). Pursuant to the exemptive relief, the Investment Adviser, with the approval of the Board, has the discretion to terminate any sub-adviser (including terminating a non-affiliated sub-adviser and replacing it with a wholly-owned sub-adviser), and to allocate and reallocate a Fund’s assets among other sub-advisers.

The Investment Adviser’s selection of sub-advisers presents conflicts of interest. The Investment Adviser will have an economic incentive to select sub-advisers that charge the lowest sub-advisory fees, to select sub-advisers affiliated with it, or to manage a portion of a Fund itself. The Investment Adviser may retain an affiliated sub-adviser (or delay terminating an affiliated sub-adviser) in order to help that sub-adviser achieve or maintain scale in an investment

strategy or increase its assets under management. The Investment Adviser may select or retain an affiliated sub-adviser even in cases where another potential sub-adviser or an existing sub-adviser might charge a lower fee or have more favorable historical investment performance.

In the event that the Investment Adviser exercises its discretion to replace a sub-adviser or appoint a new sub-adviser, a Fund will provide shareholders with information about the new sub-adviser and the new sub-advisory agreement within 90 days. The replacement of an existing sub-adviser or appointment of a new sub-adviser may be accompanied by a change to a Fund’s name and/or investment strategies.

A sub-advisory agreement can be terminated by the Investment Adviser, a Fund’s Board, or the Sub - Adviser , provided that the conditions of such termination, as set forth in the agreement, are met. In addition, a sub-advisory agreement may be terminated by a Fund’s shareholders. In the event a sub-advisory agreement is terminated, the Sub-Adviser(s) may be replaced, subject to any regulatory requirements, or the Investment Adviser may assume day-to-day investment management of the Fund.

The “manager-of-managers” structure and reliance on the exemptive relief has been approved by each Fund’s shareholders.

Shareholders are not parties to, or intended (“third-party”) beneficiaries of, any of those contractual arrangements, and those contractual arrangements are not intended to create in any individual shareholder or group of shareholders any right to enforce them against the service providers or to seek any remedy under them against the service providers, either directly or on behalf of a Fund. This paragraph is not intended to limit any rights granted to shareholders under federal or state securities laws.

CLASSES OF SHARES

Choosing a Share Class

When choosing between classes, you should carefully consider: (1) how long you plan to hold shares of a Fund; (2) the amount of your investment; (3) the expenses you will pay for each class, including ongoing annual expenses along with the initial sales charge or the contingent deferred sales charges (“CDSC”); and (4) whether you qualify for any sales charge discounts. Please review the disclosure about all of the available share classes carefully. Before investing, you should discuss with your financial intermediary which share class may be right for you.

The table below summarizes the features of the classes of shares available through this Prospectus. Fund charges may vary so you should review each Fund's fee table included in the summary section of this Prospectus as well as the section entitled “Sales Charges” in this Prospectus.

Summary of primary differences among share classes:

Class A
Initial Sales Charge	Up to 2.50% (reduced for purchases of $100,000 or more and eliminated for purchases of $500,000 or more)
Contingent Deferred Sales Charge	None (except that with respect to purchases of $500,000 or more for which the initial sales charge was waived, a charge of 1.00% applies to redemptions made within 12 months)1
Distribution and/or Shareholder Services (12b-1) Fees	0.25% annually
Purchase Maximum	None
Minimum Initial Purchase/Minimum Account Size	$1,000 ($250 for IRAs)/$1,000 ($250 for IRAs)

Contingent Deferred Sales Charge	None
Distribution and/or Shareholder Services (12b-1) Fees	None
Purchase Maximum	None
Minimum Initial Purchase/Minimum Account Size	$1,000/$1,000
Minimum Subsequent Purchases	None (At least $100/month for pre-authorized investment plan)
Minimum Initial Account Balance for Systematic Exchange Privilege	None

A contingent deferred sales charge applies to shares purchased without an initial sales charge, as part of an investment of $500,000 or more, and redeemed within 12 months of purchase.

For Class I shares, there is no minimum initial investment requirement for: (i) qualified retirement plans or other defined contribution plans and defined benefit plans that invest in the Voya funds through omnibus arrangements; (ii) employees of Voya IM who are eligible to participate in “notional” bonus programs sponsored by Voya IM; or (iii) (a) investors transacting in Class I shares through brokerage platforms that invest in the Voya funds’ Class I shares through omnibus accounts and have agreements with the Distributor to offer such shares and (b) such brokerage platforms’ omnibus accounts.

The minimum initial investment requirement for Class R6 shares is $1,000,000 for non-retirement accounts. There is no minimum initial investment requirement for retirement accounts, certain omnibus accounts, and pre-authorized investment plans.

Please refer to the minimum investments table on page 39 for additional information.

You and/or your financial intermediary should also take care to assure that you are receiving any sales charge reductions or other benefits to which you may be entitled. As an example, as is discussed below, you may be able to reduce a Class A sales charge payable by aggregating purchases to achieve breakpoint discounts. Each Fund uses the net amount invested when determining whether a shareholder has reached the required investment amount in order to be eligible for a breakpoint discount. In order to ensure that you are receiving any applicable sales charge reduction, it may be necessary for you to inform the Fund or your financial intermediary of the existence of other accounts that may be eligible to be aggregated. The SAI discusses specific classes of investors who may be eligible for a reduced sales charge. In addition, investors investing in a Fund through an intermediary should consult Appendix A to this Prospectus, which includes information regarding financial intermediary specific sales charges and related discount policies that apply to purchases through certain specified intermediaries. Before investing you should discuss which share class may be right for you with your financial intermediary.

Distribution and Service (12b-1) Fees

Certain Funds may pay a fee to the Distributor on an ongoing basis as compensation for the services the Distributor provides and the expenses it bears in connection with the sale and distribution of Fund shares (“distribution fee”) and/or in connection with personal services rendered to Fund shareholders and the maintenance of shareholder accounts (“shareholder service fee”). These payments are made pursuant to distribution and/or shareholder service plans adopted by a Fund pursuant to Rule 12b-1 of the 1940 Act (each, a “Rule 12b-1 Plan”). Because these distribution and shareholder service fees are paid on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

The table below reflects the maximum annual rates at which the distribution and/or shareholder service fees may be paid under a Rule 12b-1 Plan (calculated as a percentage of each applicable Fund's average daily net assets attributable to the particular class of shares). “ N/A ” in the table below means the Fund and/or share class does not pay distribution and/or shareholder service fees or the Fund does not currently offer that share class.

Fund	Class A	Class I	Class R6	Class W
Voya Investment Grade Credit Fund	0.25%	N/A	N/A	N/A
Voya Securitized Credit Fund	0.25%	N/A	N/A	N/A

SALES CHARGES

Each Fund makes available in a clear and prominent format, free of charge, on its website, (https://individuals.voya.com/product/share-classes-and-expenses), information regarding applicable sales loads, reduced sales charges (i.e., breakpoint discounts), sales load waivers, eligibility minimums and purchases of a Fund's shares. The website includes hyperlinks that facilitate access to the information.

Class A Shares

This section includes important information about sales charges and sales charge reduction programs available to investors in a Fund's Class A shares and describes the information or records you may need to provide to the Distributor or your financial intermediary in order to be eligible for sales charge reduction programs.

Unless you are eligible for a waiver, the public offering price you pay when you buy Class A shares is the NAV of the shares at the time of purchase, plus an initial sales charge. The initial sales charge varies depending on the size of your purchase, as set forth in the following tables. No sales charge is imposed when Class A shares are issued to you pursuant to the automatic reinvestment of income dividends or capital gains distributions. For investors investing in Class A shares through a financial intermediary, it is the responsibility of the financial intermediary to ensure that the investor obtains the proper breakpoint discount, if any.

Because the offering price is calculated to two decimal places, the dollar amount of the sales charge as a percentage of the offering price and your net amount invested for any particular purchase of Fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

Class A shares are sold subject to the following sales charge:

Your Investment	As a % of the offering price	As a % of net asset value
Less than $100,000	2.50	2.56
$100,000 - $499,999	2.00	2.04
$500,000 and over1	N/A	N/A

See CDSC - Class A Shares below.

CDSC - Class A Shares

Investments of $500,000 or More. There is no front-end sales charge if you purchase Class A shares in an amount of $500,000 or more. However, these shares will be subject to a 1.00% CDSC if they are redeemed within 12 months of purchase.

To keep your CDSC as low as possible, each time you place a request to redeem shares, a Fund will first redeem shares in your account that are not subject to a CDSC and then will sell shares that have the lowest CDSC.

There is no CDSC on shares acquired through the reinvestment of dividends and capital gains distributions.

CDSC on Exchange into Voya Credit Income Fund

You are not required to pay an applicable CDSC upon an exchange from a Fund described in this Prospectus into Voya Credit Income Fund. However, if you exchange into Voya Credit Income Fund and subsequently offer your common shares for repurchase by Voya Credit Income Fund, a Fund's CDSC will apply. After an exchange into Voya Credit Income Fund, the time period for application of the CDSC will be calculated based on the first date you acquired your shares.

Reduced or Waived Front-End Sales Charges or CDSC

The sales charge and CDSC waiver categories described in this section do not apply to customers purchasing shares of a Fund through any of the financial intermediaries specified in Appendix A to this Prospectus (each a “Specified Intermediary”). In all instances, it is the investor’s responsibility to notify a Fund or the investor’s financial intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts.

Different financial intermediaries may apply different sales charge or CDSC waivers. Please refer to Appendix A for the sales charge or CDSC waivers that are applicable to each Specified Intermediary.

Investors in a Fund could reduce or eliminate sales charges applicable to the purchase of Class A shares through utilization of the Letter of Intent, Rights of Accumulation, or Combination Privilege. These programs are summarized below and are described in greater detail in the SAI.

SALES CHARGES (continued)

You may reduce the initial sales charge on a purchase of Class A shares of a Fund by combining multiple purchases to take advantage of the breakpoints in the sales charge schedules. You may do this by:

•

Letter of Intent—Lets you purchase shares over a 13-month period and pay the same sales charge as if the shares had all been purchased at once;

•

Rights of Accumulation—Lets you add the value of shares of any open-end Voya mutual fund (excluding Voya Government Money Market Fund) you already own to the amount of your next purchase for purposes of calculating the sales charge; or

•

Combination Privilege—Shares held by investors in the Voya mutual funds which impose a CDSC may be combined with Class A shares for a reduced sales charge.

In addition, certain investors may be eligible for special purchases of Class A shares at NAV. This may be done by:

•

Reinstatement Privilege—If you sell Class A shares of a Fund (or shares of other Voya mutual funds managed by the Investment Adviser) and reinvest any of the proceeds in Class A shares of another Voya mutual fund within 90 days. For additional information regarding the reinstatement privilege, contact a Shareholder Services Representative or see the SAI; or

•

Purchases by Certain Accounts—Class A shares may be purchased at NAV by certain fee-based programs offered through selected registered investment advisers, broker-dealers, and other financial intermediaries. Class A shares may also be purchased at NAV by shareholders that purchase a Fund through a financial intermediary that offers our Class A shares uniformly on a “no load” (or reduced load) basis to you and all similarly situated customers of the intermediary in accordance with the intermediary's prescribed fee schedule for purchases of fund shares, including by shareholders that purchase shares through a financial intermediary that has entered into an agreement with the Distributor to offer shares to self-directed investment brokerage accounts that may or may not charge a transaction fee to its customers.

See the Account Application or the SAI for additional information regarding the reduction of Class A shares' charges, or contact your financial intermediary or a Shareholder Services Representative for more information.

Required Shareholder Information and Records. In order for investors in Class A shares of a Fund to take advantage of sales charge reductions, an investor or his/her financial intermediary must notify the Distributor that the investor qualifies for such reduction. If the Distributor is not notified that the investor is eligible for these reductions, the Distributor will be unable to ensure that the reduction is applied to the investor's account. An investor may have to provide certain information or records, including account statements, to his/her financial intermediary or to the Distributor to verify the investor's eligibility for breakpoint privileges or other sales charge waivers.

CDSC Waivers. If you notify a Fund's transfer agent, BNY Mellon Investment Servicing (US) Inc. (the “Transfer Agent”), at the time of redemption, the CDSC for Class A shares will be waived in the following cases:

•

Redemptions following the death or permanent disability of a shareholder if made within one year of death or the initial determination of permanent disability. The waiver is available only for shares held at the time of death or initial determination of permanent disability.

•

Mandatory distributions from “employee benefit plans” or an IRA.

•

Reinvestment of dividends and capital gains distributions.

In addition, the CDSC will be waived on the redemption of shares held through an intermediary if the intermediary has entered into an agreement with the Distributor to waive the CDSC. If you think you may be eligible for a CDSC waiver, contact your financial intermediary or a Shareholder Services Representative.

Reinstatement Privilege. If you sell Class A shares of a Fund you may be eligible for a full or prorated credit of the CDSC paid on the sale when you make an investment up to the amount redeemed in the same share class within 90 days of the eligible sale. This privilege can be used only once per calendar year. If you want to use the Reinstatement Privilege, contact your financial intermediary or a Shareholder Services Representative, or see the SAI for more information. An investor may be asked to provide information or records, including account statements, regarding shares of a Fund held in all of the investor's accounts held directly with the Trust or through a financial intermediary; any account of the investor at another financial intermediary; and accounts of related parties of the investor, such as members of the same family or household, at any financial intermediary.

HOW SHARES ARE PRICED

Each Fund is open for business every day the New York Stock Exchange (the “NYSE”) opens for regular trading (each such day, a “Business Day”). The net asset value (the “NAV”) per share for each class of each Fund is determined each Business Day as of the close of the regular trading session (“Market Close”), as determined by the Consolidated Tape Association (the “CTA”), the central distributor of transaction prices for exchange-traded securities (normally 4:00 p.m. Eastern time unless otherwise designated by the CTA). The NAV per share of each class of each Fund is calculated by taking the value of the Fund’s assets attributable to that class, subtracting the Fund’s liabilities attributable to that class, and dividing by the number of shares of that class that are outstanding. On days when a Fund is closed for business, Fund shares will not be priced, and the Fund will not process purchase or redemption orders. To the extent a Fund’s assets are traded in other markets on days when the Fund does not price its shares, the value of the Fund’s assets will likely change and you will not be able to purchase or redeem shares of the Fund.

Portfolio holdings for which market quotations are readily available are valued at market value. Investments in open-end registered investment companies that do not trade on an exchange are valued at the end of day NAV per share. The prospectuses of the open-end registered investment companies in which each Fund may invest explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing. Foreign (non-U.S.) securities’ prices are converted into U.S. dollar amounts using the applicable exchange rates as of Market Close.

When a market quotation for a portfolio security is not readily available or is deemed unreliable (for example, when trading has been halted or there are unexpected market closures or other material events that would suggest that the market quotation is unreliable) and for purposes of determining the value of other portfolio holdings, the portfolio holding is priced at its fair value. The Board has designated the Investment Adviser, as the valuation designee, to make fair value determinations in good faith. In determining the fair value of a Fund’s portfolio holdings, the Investment Adviser, pursuant to its fair valuation policy, may consider inputs from pricing service providers, broker-dealers, or a Fund’s Sub-Adviser(s). Issuer specific events, transaction price, position size, nature and duration of restrictions on disposition of the security, market trends, bid/ask quotes of brokers, and other market data may be reviewed in the course of making a good faith determination of the fair value of a portfolio holding. Because trading hours for certain foreign ( non-U.S.) securities end before Market Close, closing market quotations may become unreliable. The prices of foreign ( non - U.S.) securities will generally be adjusted based on inputs from a third party pricing service that are intended to reflect valuation changes through Market Close. Because of the inherent uncertainties of fair valuation, the values used to determine each Fund’s NAV may materially differ from the value received upon actual sale of those investments. Thus, fair valuation may have an unintended dilutive or accretive effect on the value of shareholders’ investments in each Fund.

HOW TO BUY SHARES

Customer Identification

To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify, and record information that identifies each person that opens an account, and to determine whether such person’s name appears on government lists of known or suspected terrorists and terrorist organizations.

What this means for you: a Fund, the Distributor, or a third-party selling you a Fund, must obtain the following information for each person that opens an account:

•

Name;

•

Date of birth (for individuals);

•

Physical residential address (although post office boxes are still permitted for mailing); and

•

Social Security number, taxpayer identification number, or other identifying number.

You may also be asked to show your driver’s license, passport, or other identifying documents in order to verify your identity. In addition, it may be necessary to verify your identity by cross-referencing your identification information with a consumer report or other electronic database. Additional information may be required to open accounts for corporations and other non-natural persons.

Federal law prohibits a Fund, the Distributor, and other financial institutions from opening accounts unless they receive the minimum identifying information listed above. They also may be required to close your account if they are unable to verify your identity within a reasonable time.

Each Fund and the Distributor reserve the right to reject any purchase order. Please note that cash, traveler's checks, third-party checks, money orders, and checks drawn on non-U.S. banks (even if payment may be effected through a U.S. bank) generally will not be accepted. Each Fund and the Distributor reserve the right to waive minimum investment amounts. Waiver of the minimum investment amount can increase operating expenses of a Fund. Each Fund and the Distributor reserve the right to liquidate sufficient shares to recover annual transfer agent fees or to close your account and redeem your shares should you fail to maintain your account value minimum.

Each Fund reserves the right to suspend the offering of shares.

Class A Shares

Class A shares may be purchased and sold by contacting any financial intermediary (who may impose transaction charges in addition to those described in this Prospectus) authorized to sell Fund shares. You may purchase additional shares in various ways, including through your financial adviser and by mail, telephone, on-line, and bank wire.

Class I Shares

Class I shares may be purchased without a sales charge by: (1) qualified retirement plans such as 401(a), 401(k), or other defined contribution plans and defined benefit plans; (2) 529 college savings plans; (3) insurance companies and foundations investing for their own account; (4) wrap programs offered by broker-dealers and financial institutions; (5) accounts of, or managed by, trust departments; (6) individuals whose accounts are managed by an investment adviser representative; (7) employees of Voya IM who are eligible to participate in “notional” bonus programs sponsored by Voya IM; (8) retirement plans affiliated with Voya Financial, Inc.; (9) Voya Financial, Inc. affiliates for purposes of corporate cash management; (10) other registered investment companies; and (11) (a) investors purchasing Class I shares through brokerage platforms that invest in the Voya funds’ Class I shares through omnibus accounts and have agreements with the Distributor to offer such shares and (b) such brokerage platforms’ omnibus accounts. An investor transacting in Class I shares on such brokerage platforms may be required to pay a commission and/or other forms of compensation to the broker.

Class R6 Shares

Class R6 shares may be purchased without a sales charge. Class R6 shares are offered to the following investors, provided that these investors do not require a Fund or an affiliate of a Fund (including the Investment Adviser and any affiliate of the Investment Adviser) to make, and a Fund or affiliate does not pay, any type of servicing, administrative, or revenue sharing payments with respect to Class R6 shares: (1) qualified retirement plans, including, but not limited to 401(k) plans, 457 plans, employer sponsored 403(b) plans, defined benefit plans and other accounts or plans whereby Class R6 shares are held on the books of each Fund through omnibus accounts (either at the plan level or the level of the plan administrator); (2) non-qualified deferred compensation plans; (3) other registered investment

companies; (4) Health Savings Accounts (“HSAs”) within plan level or omnibus accounts that are held on the books of a Fund; (5) other institutional investors (including, for example, endowment funds and foundations) that: (a) meet a $1,000,000 minimum initial investment requirement and (b) hold interests in a Fund through a single plan level account held directly through the Fund and not traded through an intermediary; and (6) wrap programs offered by broker-dealers and financial institutions that have entered into an agreement with the Distributor to offer Class R6 shares and invest through an omnibus account. Such availability will be subject to management's determination of the appropriateness of investment in Class R6 shares. Notwithstanding the above, affiliates of Voya, including affiliates that are intermediaries that sell Class R6 shares of a Fund, may benefit financially from the revenue Voya receives for the services it provides to Class R6 shares of a Fund.

Class R6 shares are not available to traditional and Roth IRAs, Coverdell Education Savings Accounts, SEPs, SARSEPs, SIMPLE IRAs and 529 college savings plans. Class R6 shares also are not available to adviser-sold donor-advised funds.

In addition to the above investors, certain existing Class I shareholders of each Fund may exchange all of its Class I shares for Class R6 shares of the Fund provided: (1) the shareholder meets the requirements for investment in Class R6 shares as stated above; and (2) the shareholder does not require the Fund or an affiliate of the Fund to make, and the Fund or affiliate (including the Investment Adviser and any affiliate of the Investment Adviser) does not pay, any type of servicing, administrative, or revenue sharing payments with respect to Class R6 shares. All exchanges within a Fund are subject to the discretion of the Distributor to permit or reject such exchanges.

Box 534480 Pittsburgh, PA 15253-4480	Wire the funds in the same manner described under “Opening an Account.”

Execution of Purchase Orders

Purchase orders are executed at the next NAV determined after the order is received in proper form by the Transfer Agent or the Distributor. A purchase order will be deemed to be in proper form when all of the required steps set forth under “How to Buy Shares” have been completed. If you purchase by wire, however, the order will be deemed to be in proper form after the federal funds wire has been received. If you are opening a new account and you purchase by wire, you must submit an application form prior to Market Close. If an order or payment by wire is received after Market Close, your order will not be executed until the next NAV is determined. For your transaction to be counted on the day you place your order with your broker-dealer or other financial institution, your broker-dealer or financial institution must receive your order in proper form before Market Close and transmit the order to the Transfer Agent or the Distributor in a timely manner.

You will receive a confirmation of each new transaction in your account, which also will show you the number of shares you own including the number of shares being held in safekeeping by the Transfer Agent for your account. You may rely on these confirmations in lieu of certificates as evidence of your ownership.

HOW TO SELL SHARES

You may sell shares by using the methods outlined in the following table. Under unusual circumstances, a Fund may suspend the right of redemption as allowed by the SEC or federal securities laws.

If you are a participant in a qualified retirement plan, you should make redemptions through your plan administrator or sponsor, who is responsible for transmitting orders.

Selling Shares	To Sell Some or All of Your Shares
By Contacting Your Financial Intermediary	You may sell shares by contacting your financial intermediary. Financial intermediaries may charge for their services in connection with your redemption request but neither the Fund nor the Distributor imposes any such charge.
By Mail	Send a written request specifying the Fund name and share class, your account number, the name(s) in which the account is registered, and the dollar value or number of shares you wish to redeem to: Voya Investment Management P.O. Box 534480 Pittsburgh, PA 15253-4480 If certificated shares have been issued, the certificate must accompany the written request. Corporate investors and other associations must have an appropriate certification on file authorizing redemptions. A suggested form of such certification is provided on the Account Application. A signature guarantee may be required.
By Telephone - Expedited Redemption	You may sell shares by telephone on all accounts, other than retirement accounts, unless you check the box on the Account Application which signifies that you do not wish to use telephone redemptions. To redeem by telephone, call a Shareholder Services Representative at 1-800-992-0180. Receiving Proceeds By Check: You may have redemption proceeds (up to a maximum of $10,000,000) mailed to an address which has been on record with Voya Investment Management for at least 30 days. Receiving Proceeds By Wire: You may have redemption proceeds (up to a maximum of $10,000,000) wired to your pre-designated bank account. You will not be able to receive redemption proceeds by wire unless you check the box on the Account Application which signifies that you wish to receive redemption proceeds by wire and attach a voided check. Under normal circumstances, proceeds will be transmitted to your bank on the Business Day following receipt of your instructions, provided redemptions may be made. In the event that share certificates have been issued, you may not request a wire redemption by telephone.

HOW TO SELL SHARES (continued)

Execution of Sale Requests

Sale requests are executed at the next NAV determined after the order is received in proper form by the Transfer Agent or the Distributor. For your transaction to be counted on the day you place your sale request with your broker-dealer or other financial institution, your broker-dealer or financial institution must receive your sale request in proper form before Market Close and transmit the sale request to the Transfer Agent or the Distributor in a timely manner.

Payments

Normally, payment for shares redeemed will typically be made within one business day after receipt by the Transfer Agent of a request in good order. Each Fund can delay payment of the redemption proceeds for up to 7 days and may suspend redemptions and/or further postpone payment proceeds when the NYSE is closed (other than weekends or holidays) or when trading thereon is restricted or during emergency or other circumstances, including as determined by the SEC. When you place a request to redeem shares for which the purchase money has not yet been collected, the request will be executed at the next determined NAV, but a Fund will not release the proceeds until your purchase payment clears. This may take up to 30 days. A redemption request made within 30 calendar days after submission of a change of address is permitted only if the request is in writing and is accompanied by a medallion signature guarantee. Redemption requests of an amount of $10 million or more must be submitted in writing by an authorized person.

A medallion signature guarantee may be required in certain circumstances. A request to change the bank designated to receive wire redemption proceeds must be received in writing, signed by an authorized person, and accompanied by a medallion signature guarantee from any eligible guarantor institution. In addition, if you wish to have your redemption proceeds transferred by wire to an account other than your designated bank account, paid to someone other than the shareholder of record, or sent somewhere other than the shareholder’s address of record, you must provide a medallion signature guarantee with your written redemption instructions. Please see the SAI for more details on the medallion signature guarantee program.

Each Fund will typically pay redemption proceeds in cash using cash held by each Fund, with cash generated by each Fund through the sale of cash equivalents and other Fund assets or by borrowing cash pursuant to each Fund’s line of credit. A Fund may, however, determine in its absolute discretion to distribute non-cash assets in kind in complete or partial satisfaction of its obligation to pay redemption proceeds to a shareholder. In such a case, a Fund could elect to make payment in securities or other assets for redemptions that exceed the lesser of $ 250,000 or 1% of its net assets during any 90 - day period for any one record shareholder. Non- cash assets distributed by a Fund likely will not represent a pro rata distribution of assets held in the Fund’ s portfolio . A shareholder' s receipt of non- cash redemption proceeds may be less favorable to the shareholder than receipt of cash proceeds for a number of reasons, including, without limitation, costs and potential delays relating to the sale of the non- cash assets, potential illiquidity of the non-cash assets, and the potential inability of the shareholder to realize on the sale of the non- cash assets cash proceeds equal to the cash proceeds it would have received from a Fund. A Fund has no obligation to distribute non- cash assets, including in circumstances when doing so may benefit a redeeming shareholder or may reduce or eliminate transaction costs and/or the realization of capital gains that may need to be distributed to shareholders, which such distributions will be taxable to shareholders that hold their shares in a taxable account.

Telephone Orders

Neither a Fund nor the Transfer Agent will be responsible for the authenticity of phone instructions or losses, if any, resulting from unauthorized shareholder transactions if they reasonably believe that such instructions were genuine. Each Fund and the Transfer Agent have established reasonable procedures to confirm that instructions communicated by telephone are genuine. These procedures include recording telephone instructions for exchanges and expedited redemptions, requiring the caller to give certain specific identifying information, and providing written confirmation to shareholders of record not later than 5 days following any such telephone transactions. If a Fund or the Transfer Agent do not employ these procedures, they may be liable for any losses due to unauthorized or fraudulent telephone instructions.

HOW TO SELL SHARES (continued)

Small Accounts

Due to the relatively high cost of handling small investments, a Fund reserves the right, upon 30 days’ prior written notice, to redeem at NAV (less any applicable deferred sales charge), the shares of any shareholder whose account (except for IRAs) has a total value that is less than a Fund's minimum. Before a Fund redeems such shares and sends the proceeds to the shareholder, it will notify the shareholder that the value of the shares in the account is less than the minimum amount allowed and will allow the shareholder 30 days to make an additional investment in an amount that will increase the value of the account to the minimum before the redemption is processed. Your account will not be closed if its drop in value is due to Fund performance.

HOW TO EXCHANGE SHARES

Exchanges Between Voya Mutual Funds

You may exchange shares of a Fund for shares of the same class of any other Voya mutual fund, except for Voya Corporate Leaders® Trust Fund, without paying any additional sales charge, if you otherwise meet the eligibility requirements of the class of shares of the Voya mutual fund to be received in the exchange. If you purchase Class A shares of Voya Government Money Market Fund and did not pay a sales charge, you must pay the applicable sales charge on an exchange into Class A shares of another Voya mutual fund.

If you exchange shares of a Fund that are subject to a CDSC into shares of another Voya mutual fund that are subject to a CDSC, the CDSC will continue to apply to your new shares at the same CDSC rate that was applicable to your original shares. Your new shares will continue to age for CDSC purposes from the date that the original shares were purchased.

Exchanges Between Classes of a Fund

You may exchange Class W shares for Class I shares within a Fund, or you may exchange Class A shares and Class I shares for any other class within a Fund, if you otherwise meet the eligibility requirements of the class of shares to be received in the exchange, except that: (1) you may not exchange shares that are subject to a CDSC until the CDSC period has expired, unless the Distributor approves the exchange and determines that no CDSC is payable in connection with the exchange; and (2) you may not exchange Class A shares for Class W shares unless you acquired the Class A shares through a Voya approved broker-dealer (currently, Voya Financial Advisors, Inc.).

Certain existing Class I shareholders of a Fund may exchange their Class I shares for Class R6 shares of the Fund provided: (1) the shareholder meets the requirements for investment in Class R6 shares as stated in the section of this Prospectus entitled “How to Buy Shares”; and (2) the shareholder does not require the Fund or an affiliate (including the Investment Adviser and any affiliate of the Investment Adviser) of the Fund to make, and the Fund or affiliate does not pay, any type of servicing, administrative, or revenue sharing payments with respect to Class R6 shares.

All exchanges within a Fund are subject to the discretion of the Distributor to permit or reject such exchanges. Shareholders generally should not recognize gain or loss for U.S. federal income tax purposes from an exchange between classes of shares within a Fund provided that the transaction is undertaken and processed, with respect to any shareholder, as a direct exchange transaction. Shareholders should consult their tax advisors as to the federal, state, local, and non-U.S. tax consequences of an exchange between classes of shares within a Fund.

Exchanges between classes of shares within a Fund are not subject to the frequent trading and market timing policies of Voya mutual funds.

Additional Information About Exchanges

Fees and expenses differ among Voya mutual funds and among share classes of the same fund. Please read the prospectus for the Voya mutual fund and share class you are interested in prior to exchanging into that Voya mutual fund or share class. Contact your financial intermediary or consult your plan documents for additional information.

An exchange of shares of a Fund for shares of another Voya mutual fund is treated as a sale and purchase of shares and may result in the recognition of a gain or loss for federal and state income tax purposes. For exchanges between Voya mutual funds, you should consult your own tax advisor for advice about the particular federal, state, and local tax consequences to you of the exchange. The total value of shares being exchanged must at least equal the minimum investment requirement of the Voya mutual fund into which they are being exchanged.

If you exchange into Voya Credit Income Fund, your ability to sell or liquidate your investment will be limited. Voya Credit Income Fund is a closed-end interval fund and does not redeem its shares on a daily basis. It is not expected that a secondary market for Voya Credit Income Fund's shares will develop, so you will not be able to sell them through a broker or other investment professional. To provide a measure of liquidity, Voya Credit Income Fund will normally make monthly repurchase offers for not less than 5% of its outstanding common shares. If more than 5% of Voya Credit Income Fund's common shares are tendered, you may not be able to completely liquidate your holdings in any one month. You also would not have liquidity between these monthly repurchase dates. Investors exercising the exchange privilege into Voya Credit Income Fund should carefully review the prospectus of that fund. Investors may obtain a copy of the Voya Credit Income Fund prospectus or any other Voya mutual fund prospectus by calling 1-800-992-0180 or by going to www.voyainvestments.com.

HOW TO EXCHANGE SHARES (continued)

In addition to each Fund available in this Prospectus, the Distributor offers many other funds. Shareholders exercising the exchange privilege with any other Voya mutual fund should carefully review the prospectus of that fund before exchanging their shares. Investors may obtain a copy of a prospectus of any Voya mutual fund not discussed in this Prospectus by calling 1-800-992-0180 or by going to www.voyainvestments.com.

You will automatically have the ability to request an exchange between Voya mutual funds by calling a Shareholder Services Representative unless you mark the box on the Account Application that indicates that you do not wish to have the telephone exchange privilege. Each Fund may change or cancel its exchange policies at any time, upon 60 days’ prior notice to shareholders.

Systematic Exchange Privilege

Subject to the information and limitations outlined above, you may elect to have a specified dollar amount of shares systematically exchanged, monthly, quarterly, semi-annually, or annually from your account to an identically registered account in the same class of any other open-end Voya mutual fund, except for Voya Corporate Leaders® Trust Fund. This exchange privilege may be modified at any time or terminated upon 60 days' prior written notice to shareholders.

FREQUENT TRADING - MARKET TIMING

Each Fund is intended for long-term investment and not as a short-term trading vehicle. Accordingly, organizations or individuals that use market timing investment strategies should not purchase shares of a Fund. Each Fund reserves the right, in its sole discretion and without prior notice, to reject, restrict, or refuse purchase orders whether directly or by exchange, including purchase orders that have been accepted by a shareholder's or retirement plan participant's intermediary, that the Fund determines not to be in the best interest of the Fund. Such action may include, but not be limited to: rejecting additional purchase orders, whether directly or by exchange; extending settlement of a redemption up to 7 days; rejecting all purchase orders from broker-dealers or their registered representatives suspected of violating the Fund's frequent trading policy; or termination of the selling group agreement or other agreement with broker-dealers or other financial intermediaries associated with frequent trading. A Fund will not be liable for any loss resulting from rejected orders or other actions as described above.

Each Fund believes that market timing or frequent, short-term trading in any account, including a retirement plan account, is not in the best interest of the Fund or its shareholders. Due to the disruptive nature of this activity, it can adversely affect the ability of the Investment Adviser or Sub-Adviser (if applicable) to invest assets in an orderly, efficient manner. Frequent trading can raise Fund expenses through: increased trading and transaction costs; increased administrative costs; and lost opportunity costs. This in turn can have an adverse effect on Fund performance.

Funds that invest in foreign (non-U.S.) securities may present greater opportunities for market timers and thus be at a greater risk for excessive trading. If an event occurring after the close of a foreign market, but before the time a Fund computes its current NAV, causes a change in the price of the foreign (non-U.S.) security and such price is not reflected in its current NAV, investors may attempt to take advantage of anticipated price movements in securities held by a Fund based on such pricing discrepancies. This is often referred to as “price arbitrage.” Such price arbitrage opportunities may also occur in funds which do not invest in foreign (non-U.S.) securities. For example, if trading in a security held by a Fund is halted and does not resume prior to the time it calculates its NAV such “stale pricing” presents an opportunity for investors to take advantage of the pricing discrepancy. Similarly, funds that hold thinly-traded securities, such as certain small-capitalization securities, may be exposed to varying levels of pricing arbitrage. Each Fund has adopted fair valuation policies and procedures intended to reduce its exposure to price arbitrage, stale pricing and other potential pricing discrepancies. However, to the extent that a Fund does not immediately reflect these changes in market conditions, short-term trading may dilute the value of the Fund’s shares which negatively affects long-term shareholders.

The Board has adopted policies and procedures designed to deter frequent, short-term trading in shares of each Fund. In general, shareholders may make exchanges among their accounts with Voya mutual funds once every 30 days. However, each Fund prohibits frequent trading. Each Fund has defined frequent trading as follows:

•

Any shareholder or financial adviser initiated exchanges among all their accounts with a Fund within 30 calendar days of a previous exchange. All exchanges occurring on the same day for all accounts (individual, IRA, 401(k), etc.) beneficially owned by the same shareholder will be treated as a single transaction for purposes of this policy;

•

Trading deemed harmful or excessive by a Fund (including but not limited to patterns of purchases and redemptions), in its sole discretion; and

•

Trades initiated by financial advisers, among multiple shareholder accounts, that in the aggregate are deemed harmful or excessive.

The following transactions are excluded when determining whether trading activity is excessive:

•

Purchases and sales of Fund shares in the amount of $5,000 or less;

•

Transfers associated with systematic purchases or redemptions;

•

Purchases and sales of funds that affirmatively permit short-term trading;

•

Rebalancing to facilitate fund-of-fund arrangements or a Fund's systematic exchange privileges;

•

Purchases or sales initiated by Voya mutual funds; and

•

Transactions subject to the trading policy of an intermediary that a Fund deems materially similar to the Fund's policy.

Please note that while money market funds permit short-term trading, an exchange between a money market fund and another fund that does not permit short-term trading will count as an exchange for purposes of this policy.

FREQUENT TRADING - MARKET TIMING (continued)

If a violation of the policy is identified, the following action will be taken:

•

Upon the first violation of this policy in a calendar year, purchase and exchange privileges shall be suspended for 90 days. For example, if an exchange is initiated on February 1st, and a second exchange is initiated on February 15th, trading privileges shall be suspended for 90 days from February 1st.

•

Upon a second violation in a calendar year, purchase and exchange privileges shall be suspended for 180 days.

•

No purchases or exchanges will be permitted in the account and all related accounts bearing the same Tax ID or equivalent identifier.

On the next Business Day following the end of the 90 or 180 day suspension, any trading restrictions placed on the account(s) shall be removed.

Each Fund reserves the right to modify this policy at any time without prior notice.

Although the restrictions described above are designed to discourage frequent, short-term trading, none of them alone, nor all of them taken together, can eliminate the possibility that frequent, short-term trading activity in a Fund will occur. Moreover, in enforcing such restrictions, a Fund is often required to make decisions that are inherently subjective. Each Fund strives to make these decisions to the best of its abilities in a manner that it believes is in the best interest of shareholders.

Shareholders may invest in a Fund through omnibus account arrangements with financial intermediaries. Omnibus accounts permit intermediaries to aggregate their clients' transactions and in these circumstances, the identity of the shareholder is often unknown. Such intermediaries include broker-dealers, banks, investment advisers, record keepers, retirement plans, and fee-based accounts such as wrap fee programs. Omnibus accounts generally do not identify customers' trading activity on an individual basis. The Investment Adviser or its affiliated entities have agreements in place with intermediaries which require such intermediaries to provide detailed account information, including trading history, upon request of a Fund. There is no assurance that the Investment Adviser or its affiliated entities will request such information with sufficient frequency to detect or deter excessive trading or that review of such information will be sufficient to detect or deter excessive trading in omnibus accounts effectively.

In some cases, a Fund will rely on the intermediaries' excessive trading policies and such policies shall define the trading activity in which the shareholder may engage. This shall be the case where a Fund is used in certain retirement plans offered by affiliates. With trading information received as a result of the agreements, a Fund may make a determination that certain trading activity is harmful to the Fund and its shareholders even if such activity is not strictly prohibited by the intermediaries' excessive trading policy. As a result, a shareholder investing directly or indirectly in a Fund may have their trading privileges suspended without violating the stated excessive trading policy of the intermediary.

PAYMENTS TO FINANCIAL INTERMEDIARIES

Persons licensed with FINRA as a registered representative (often referred to as a broker or financial adviser) and associated with a specific broker-dealer may receive compensation from each Fund for providing services which are primarily intended to result in the sale of Fund shares. The Distributor has an agreement in place with each broker-dealer selling each Fund defining specifically what that broker-dealer will be paid for the sale of a particular Voya mutual fund. The broker-dealer then pays the registered representative who sold you the mutual fund some or all of what they receive from Voya. A registered representative may receive a payment when the sale is made and in some cases, can continue to receive payments while you are invested in the mutual fund. In addition, other entities may receive compensation from each Fund for providing services which are primarily intended to result in the sale of Fund shares, so long as such entities are permitted to receive these fees under applicable rules and regulations.

The Distributor may pay, from its own resources, additional fees to these broker-dealers or other financial institutions including affiliated entities. These additional fees paid to intermediaries may take the following forms: (1) a percentage of that entity’s customer assets invested in Voya mutual funds; (2) a percentage of that entity's gross sales; or (3) some combination of these payments. Depending on the broker-dealer's satisfaction of the required conditions, these payments may be periodic and may be up to: (1) 0.30% per annum of the value of each Fund's shares held by the broker-dealer’s customers; or (2) 0.30% of the value of each Fund's shares sold by the broker-dealer during a particular period. For example, if that initial investment averages a value of $10,000 over the year, the Distributor could pay a maximum of $30 on those assets. If you invested $10,000, the Distributor could pay a maximum of $30 for that sale.

Voya, out of its own resources and without additional cost to each Fund or its shareholders, may provide additional cash or non-cash compensation to intermediaries selling shares of each Fund, including affiliates of Voya. These amounts would be in addition to the distribution payments made by each Fund under the distribution agreements. Management personnel of Voya may receive additional compensation if the overall amount of investments in funds advised by Voya meets certain target levels or increases over time.

Voya may provide additional cash or non-cash compensation to third parties selling our mutual funds including affiliated companies. This may take the form of cash incentives and non-cash compensation and may include, but is not limited to: cash; merchandise; trips; occasional entertainment; meals or tickets to a sporting event; client appreciation events; payment for travel expenses (including meals and lodging) to pre-approved training and education seminars; and payment for advertising and sales campaigns. The Distributor may also pay concessions in addition to those described above to broker-dealers so that Voya mutual funds are made available by those broker-dealers for their customers. The Sub-Adviser of each Fund may contribute to non-cash compensation arrangements.

The compensation paid by Voya to a financial intermediary is typically paid continually over time, during the period when the intermediary’s clients hold investments in the Voya mutual funds. The amount of continuing compensation paid by Voya to different financial intermediaries for distribution and/or shareholder services varies. The compensation is typically a percentage of the value of the financial intermediary’s clients’ investments in Voya mutual funds or a per account fee. The variation in compensation may, but will not necessarily, reflect enhanced or additional services provided by the intermediary.

Voya or a Voya mutual fund may pay service fees to intermediaries for administration, recordkeeping, and other shareholder services. Intermediaries receiving these payments may include, among others, brokers, financial planners or advisers, banks, and insurance companies. The Voya mutual funds may reimburse Voya for some or all of the payments made by Voya to intermediaries for these services.

In some cases, a financial intermediary may hold its clients’ mutual fund shares in nominee or street name. These financial intermediaries may (though they will not necessarily) provide services including, among other things: processing and mailing trade confirmations; capturing and processing tax data; issuing and mailing dividend checks to shareholders who have selected cash distributions; preparing record date shareholder lists for proxy solicitations; collecting and posting distributions to shareholder accounts; and establishing and maintaining systematic withdrawals and automated investment plans and shareholder account registrations.

PAYMENTS TO FINANCIAL INTERMEDIARIES (continued)

The top firms Voya paid to sell its mutual funds as of the last calendar year are:

Advisor Group, Inc.; Ameriprise Financial Services, LLC; Broadridge Business Process Outsourcing, LLC; Cetera Financial Holdings, Inc.; Charles Schwab & Co.

Your registered representative or broker-dealer could have a financial interest in selling you a particular mutual fund, or the mutual funds of a particular company, to increase the compensation they receive. Please make sure you read fully each mutual fund prospectus and discuss any questions you have with your registered representative.

Class R6

Voya mutual funds are distributed by the Distributor. The Distributor is a broker-dealer that is licensed to sell securities. The Distributor generally does not sell directly to the public but sells and markets its products through financial intermediaries. Each Voya mutual fund also has an investment adviser which is responsible for managing the money invested in each of the mutual funds. No dealer compensation is paid from the sale of Class R6 shares of a Fund. Class R6 shares do not have sales commissions, pay 12b-1 fees, or make payments to financial intermediaries for assisting the Distributor in promoting the sales of a Fund's shares. In addition, neither a Fund nor its affiliates (including the Investment Adviser and any affiliate of the Investment Adviser) make any type of administrative, service, or revenue sharing payments in connection with Class R6 shares. Notwithstanding the foregoing, affiliates of Voya, including affiliates that are intermediaries that sell Class R6 shares of a Fund, may benefit financially from the revenue Voya receives for the services it provides to Class R6 shares of a Fund.

DIVIDENDS, DISTRIBUTIONS, AND TAXES

Dividends and Distributions

Each Fund generally distributes most or all of its net earnings in the form of dividends, consisting of ordinary income and capital gains distributions. Each Fund distributes capital gains, if any, annually. Each Fund also declares dividends daily and pays dividends consisting of ordinary income, if any, monthly.

From time to time a portion of a Fund’s distributions may constitute a return of capital. To comply with federal tax regulations, each Fund may also pay an additional capital gains distribution.

Dividend Reinvestment

Unless you instruct a Fund to pay you dividends in cash, dividends and distributions paid by the Fund will be reinvested in additional shares of the Fund. You may, upon written request or by completing the appropriate section of the Account Application, elect to have all dividends and other distributions paid on shares of a Fund invested in another Voya mutual fund that offers the same class of shares.

Tax Consequences

The tax discussion in this Prospectus is only a summary of certain U.S. federal income tax issues generally affecting each Fund and its shareholders. The following assumes that each Fund's shares will be capital assets in the hands of a shareholder. The Investment Adviser is not obligated to consider the tax consequences related to its management of a Fund's investments or other activities. It is possible that the actions taken by a Fund or the Investment Adviser on the Fund’s behalf could be disadvantageous to shareholders that hold shares through a taxable account. However, such actions likely will have no tax effect to shareholders that invest through a tax-advantaged account. Circumstances among investors may vary, so you are encouraged to discuss an investment in a Fund with your tax advisor.

Each Fund will distribute all, or substantially all, of its net investment income and net capital gains (i.e., the excess of net long-term capital gains over net short-term capital losses, in each case determined with reference to any loss carryforwards) to its shareholders each year. Although a Fund will not be taxed on amounts it distributes, most shareholders will be taxed on amounts they receive.

Distributions, whether received as cash or reinvested in additional shares, may be subject to U.S. federal income taxes and may also be subject to state or local taxes. For mutual funds generally, dividends from net investment income (other than qualified dividend income and capital gain dividends) and distributions of net short-term capital gains are taxable to you as ordinary income under federal income tax laws whether paid in cash or in additional shares. Distributions properly reported as capital gain dividends are taxable as long term capital gains regardless of the length of time you have held the shares and whether you were paid in cash or additional shares.

Distributions made to a non-corporate shareholder out of “qualified dividend income,” if any, received by a Fund will be subject to tax at the lower rates applicable to net capital gains, provided that the shareholder meets certain holding period and other requirements with respect to its shares.

Selling or exchanging your Fund shares is a taxable event and may result in capital gain or loss. A capital gain or capital loss may be realized from an ordinary redemption of shares or an exchange of shares between two mutual funds. Any such capital gain or loss will generally be long term if the shares sold or exchanged were held for more than one year; otherwise, such gain or loss will be short term. Any capital loss incurred on the sale or exchange of Fund shares held for six months or less will be treated as a long-term capital loss to the extent of capital gain dividends received with respect to such shares. Additionally, any loss realized on a sale, redemption or exchange of Fund shares may be disallowed under “wash sale” rules to the extent the shares disposed of are replaced with other shares of that same Fund within a period of 61 days beginning 30 days before and ending 30 days after the shares are disposed of, such as pursuant to a dividend reinvestment in shares of the Fund. If disallowed, the loss will be reflected in an adjustment to the tax basis of the shares acquired. You are responsible for any tax liabilities generated by your transactions.

You will be notified annually of the amount of income, dividends and net capital gains distributed. If you purchase shares of a Fund through a financial intermediary, that entity will provide this information to you.

Each Fund intends to qualify and be eligible for treatment each year as a regulated investment company (“RIC”). A RIC generally is not subject to tax at the fund level on income and gains from investments that are timely distributed to shareholders. However, a Fund’s failure to qualify as a RIC would result in fund level taxation and therefore, a reduction in income available for distribution.

DIVIDENDS, DISTRIBUTIONS, AND TAXES (continued)

An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds certain threshold amounts.

Each Fund is required to withhold a portion of all taxable dividends, distributions, and redemption proceeds payable to any noncorporate shareholder that does not provide the Fund with the shareholder's correct taxpayer identification number or certification that the shareholder is not subject to backup withholding. This is not an additional tax but can be credited against your U.S. federal income tax liability.

Shareholders that invest in a Fund through a tax advantaged account, such as a qualified retirement plan, generally will not have to pay tax on dividends or gains from the sale or exchange of Fund shares until they are distributed from the account. These accounts are subject to complex tax rules, and you should consult your tax advisor about investing through such an account.

Buying a Dividend. Unless your investment is in a tax-advantaged account, you may want to avoid buying shares shortly before a Fund makes a distribution as doing so can increase your tax liability. If you buy shares when a Fund has declared but not distributed ordinary income or capital gains, you will pay the full price for the shares and later receive a portion of the price back in the form of a taxable dividend. This is known as “buying a dividend.” To avoid buying a dividend, you may want to consult your tax advisor or check a Fund's distribution schedule before you invest.

Foreign shareholders invested in a Fund should consult with their tax advisors as to if and how the U.S. federal income tax law and its withholding requirements apply to them. Generally, a Fund will withhold 30% (or lower applicable treaty rate) on distributions to foreign shareholders.

Foreign Taxes. Investment income and proceeds received by a Fund from sources within foreign countries may be subject to foreign withholding or other taxes. The United States has entered into tax treaties with many foreign countries which may entitle a Fund to a reduced rate of such taxes or an exemption from taxes on such income or proceeds. It is impossible to determine the effective rate of foreign tax for a Fund in advance since the amount of the assets to be invested within various countries is not known.

Cost Basis Reporting. The Internal Revenue Service requires mutual fund companies and brokers to report on Form 1099-B the cost basis on the sale or exchange of Fund shares acquired on or after January 1, 2012 (“covered shares”). If you acquire and hold shares directly through a Fund and not through a financial intermediary, the Fund will use an average cost single category methodology for tracking and reporting your cost basis on covered shares, unless you request, in writing, another cost basis reporting methodology.

Please see the SAI for further information regarding tax matters.

ACCOMPANYING NOTES TO FINANCIAL HIGHLIGHTS

(1)

Total return is calculated assuming reinvestment of all dividends, capital gain distributions, and return of capital distributions, if any, at net asset value, does not reflect the effect of any wrap fees and excluding the deduction of sales charges or contingent deferred sales charges, if applicable. Total return for periods less than one year is not annualized.

(2)

Annualized for periods less than one year.

(3)

Ratios reflect operating expenses of a Fund. Expenses before reductions/additions do not reflect amounts reimbursed or recouped by the Investment Adviser and/or the Distributor or reductions from brokerage service arrangements or other expense offset arrangements and do not represent the amount paid by a Fund during periods when reimbursements or reductions occur. Expenses net of fee waivers reflect expenses after reimbursement by the Investment Adviser and/or the Distributor or recoupment of previously reimbursed fees by the Investment Adviser, but prior to reductions from brokerage service arrangements or other expense offset arrangements. Expenses net of all reductions/additions represent the net expenses paid by a Fund. Net investment income (loss) is net of all such additions or reductions.

(4)

Commencement of operations.

•

Calculated using average number of shares outstanding throughout the year or period.

Amount is less than $0.005 or 0.005% or more than $(0.005) or (0.005)%.

EDWARD D. JONES & CO., L.P. (“EDWARD JONES”)

Policies Regarding Transactions Through Edward Jones

The following information has been provided by Edward Jones:

The following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder's responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of Voya funds and Voya 529 Plans or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

Breakpoints

•

Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the Prospectus.

Rights of Accumulation (“ROA”)

•

The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and assets held in group retirement plans) of the Voya funds and Voya 529 Plans held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.

•

The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.

•

ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

Letter of Intent (“LOI”)

•

Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.

•

If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.
