INVESTMENT OBJECTIVE

The Portfolio seeks investment results (before fees and expenses) that correspond to the total return (which includes capital appreciation and income) of the FTSE 100 Index^® (“Index”).

FEES AND EXPENSES OF THE PORTFOLIO

The table describes the fees and expenses that you may pay if you buy and hold shares of the Portfolio. The table does not reflect fees or expenses that are, or may be, imposed under your variable annuity contracts or variable life insurance policies (“Variable Contract”) or a qualified pension or retirement plan (“Qualified Plan”). For more information on these charges, please refer to the documents governing your Variable Contract or consult your plan administrator.

Annual Portfolio Operating Expenses
Expenses you pay each year as a % of the value of your investment

Class		ADV	I
Management Fee	%	0.60	0.60
Distribution and/or Shareholder Services (12b-1) Fees	%	0.50	None
Administrative Services Fee	%	0.10	0.10

1 The adviser is contractually obligated to waive 0.25% of the management fee through May 1, 2015. The administrator is contractually obligated to waive the administrative services fee through May 1, 2015. These waivers will only renew if the adviser and/or the administrator elects to renew them and they are not eligible for recoupment. Notwithstanding the foregoing, termination or modification of these obligations requires approval by the Portfolio’s board.

Expense Examples $

The Examples are intended to help you compare the cost of investing in shares of the Portfolio with the costs of investing in other mutual funds. The Examples do not reflect expenses

and charges which are, or may be, imposed under your Variable Contract or Qualified Plan. The Examples assume that you invest $10,000 in the Portfolio for the time periods indicated. The Examples also assume that your investment had a 5% return each year and that the Portfolio's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class		1 Yr	3 Yrs	5 Yrs	10 Yrs
ADV	$	94	368	663	1,503
I	$	43	211	393	921

The Examples reflect 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.

Portfolio Turnover

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

During the most recent fiscal year, the Portfolio's portfolio turnover rate was 8% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of companies, which are at the time of purchase, included in the Index; convertible securities that are convertible into stocks included in the Index; other derivatives whose economic returns are, by design, closely equivalent to the returns of the Index or its components; and exchange-traded funds. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Under normal market conditions, the Portfolio invests all, or substantially all of its assets in these securities.

1 of 4

The Portfolio may invest in other investment companies to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and exemptive orders thereunder (“1940 Act”).

The Portfolio currently invests principally in common stocks and employs a “passive management” approach designed to track the performance of the Index.

The Index includes 100 of the most highly capitalized companies located in the United Kingdom listed on the London Stock Exchange. As of February 28, 2014, portions of the Index were focused in the financials sector, the energy sector (including a focus in the oil, gas and consumable fuels industry), and the consumer staples sector.

The Portfolio is non-diversified, which means it may invest a significant portion of its assets in a single issuer.

The Portfolio may not always hold all of the same securities as the Index. The Portfolio may also invest in stock index futures and other derivatives as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Portfolio's cash position. Although the Portfolio attempts to track, as closely as possible, the performance of the Index, the Portfolio does not always perform exactly like the Index. Unlike the Index, the Portfolio has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.

The sub-adviser (“Sub-Adviser”) may sell a security when the security's percentage weighting in the Index is reduced, when the security is removed from the Index, or for other reasons.

The Portfolio 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 Portfolio. Any of the following risks, among others, could affect Portfolio performance or cause the Portfolio to lose money or to underperform market averages of other funds.

Company    The price of a given company's stock could decline or underperform for many reasons including, among others, poor management, financial problems, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.

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 securities, such as interest rate and credit risk. In addition, because convertible securities react to changes in the value of the stocks into which they convert, they are subject to market risk.

Credit    Prices of bonds and other debt instruments can fall if the issuer's actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay altogether.

Currency    To the extent that the Portfolio invests directly 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.

Derivative Instruments    Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in interest rates and liquidity risk. The use of certain derivatives may also have a leveraging effect which may increase the volatility of the Portfolio and reduce its returns. Derivatives may not perform as expected, so the Portfolio may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Portfolio to the risk of improper valuation.

Focused Investing    To the extent that the Portfolio invests a substantial portion of its assets in a particular industry, sector, market segment, or geographical area, its investments will be sensitive to developments in that industry, sector, market segment, or geographical area. The Portfolio assumes the risk that changing economic conditions; changing political or regulatory conditions; or natural and other disasters affecting the particular industry, sector, market segment, or geographical area in which the Portfolio focuses its investments could have a significant impact on its investment performance and could ultimately cause the Portfolio to underperform, or be more volatile than, other funds that invest more broadly.

Foreign Investments    Investing in foreign (non-U.S.) securities may result in the Portfolio experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due to: smaller markets; differing reporting, accounting, and auditing standards; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments. 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.

Index Strategy    The index selected may underperform the overall market and the Portfolio might fail to track its target index. The correlation between the Portfolio and index performance may be affected by the Portfolio's expenses and the timing of purchases and redemptions of the Portfolio's shares. The

2 of 4

Summary Prospectus  Voya FTSE 100 Index^® Portfolio

Portfolio's actual holdings might not match the Index and the Portfolio's effective exposure to index securities at any given time may not equal 100%.

Interest Rate    With bonds and other fixed rate debt instruments, a rise in interest rates generally causes values to fall; conversely, values generally rise as interest rates fall. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk. In the case of inverse securities, the interest rate generally will decrease when the market rate of interest to which the inverse security is indexed increases. As of the date of this Prospectus, interest rates in the United States are at or near historic lows, which may increase the Portfolio's exposure to risks associated with rising interest rates. Rising interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. For fixed-income securities, an increase in interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain Portfolio investments, adversely affect values, and increase a Portfolio’s costs. If dealer capacity in fixed-income markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in the fixed income markets.

Issuer Non-Diversification    The Portfolio is classified as a “non-diversified” investment company and, therefore, is subject to the risks of focusing investments in a small number of issuers, industries or foreign currencies, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be.

Liquidity    If a security is illiquid, the Portfolio might be unable to sell the security at a time when the Portfolio's manager might wish to sell, and the security could have the effect of decreasing the overall level of the Portfolio's liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, which could vary from the amount the Portfolio could realize upon disposition. The Portfolio may make investments that become less liquid in response to market developments or adverse investor perception. The Portfolio could lose money if it cannot sell a security at the time and price that would be most beneficial to the Portfolio.

Market    Stock prices may be volatile and are affected by the real or perceived impacts of such factors as economic conditions and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to Portfolio costs and impair the ability of the Portfolio 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-sized companies causing the Portfolio that invests in these companies to increase in value more rapidly than a fund that invests in larger, fully-valued 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, and a more limited trading market for their stocks as compared with larger companies. As a result, stocks of mid- and small-capitalization companies may decline significantly in market downturns.

Other Investment Companies    The main risk of investing in other investment companies, including exchange-traded funds, is the risk that the value of the securities underlying an investment company might decrease. Because the Portfolio may invest in other investment companies, 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 expenses of the Portfolio.

Securities Lending    Securities lending involves two primary risks: “investment risk” and “borrower default risk.” Investment risk is the risk that the Portfolio will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Portfolio will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

An investment in the Portfolio 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 Portfolio. The following bar chart shows the changes in the Portfolio's performance from year to year, and the table compares the Portfolio's performance to the performance of a broad-based securities market index/indices for the same period. The Portfolio'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 Portfolio’s Class ADV shares. Other class shares’ performance would be higher than Class ADV shares’ performance because of the higher expenses paid by Class ADV shares. Performance in the Average Annual Total Returns table does not include insurance-related charges imposed under a Variable Contract or expenses related to a Qualified Plan. If these charges or expenses were included, performance would be lower. Thus, you should not compare the Portfolio's performance directly with the performance information of other investment products

PURCHASE AND SALE OF PORTFOLIO SHARES

Shares of the Portfolio are not offered directly to the public. Purchase and sale of shares may be made only by separate accounts of insurance companies serving as investment options under Variable Contracts or by Qualified Plans, custodian

accounts, and certain investment advisers and their affiliates, other investment companies, or permitted investors. Please refer to the prospectus for the appropriate insurance company separate account, investment company, or your plan documents for information on how to direct investments in, or sale from, an investment option corresponding to the Portfolio and any fees that may apply. Participating insurance companies and certain other designated organizations are authorized to receive purchase orders on the Portfolio's behalf.

TAX INFORMATION

Distributions made by the Portfolio to a Variable Contract or Qualified Plan, and exchanges and redemptions of Portfolio shares made by a Variable Contract or Qualified Plan, ordinarily do not cause the corresponding contract holder or plan participant to recognize income or gain for federal income tax purposes. See the accompanying contract prospectus or the governing documents of your Qualified Plan for information regarding the federal income tax treatment of the distributions to your Variable Contract or Qualified Plan and the holders of the contracts or plan participants.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you invest in the Portfolio through a Variable Contract issued by an insurance company or through a Qualified Plan that, in turn, was purchased or serviced through an insurance company, broker-dealer or other financial intermediary, the Portfolio and its adviser or distributor or their affiliates may: (1) make payments to the insurance company issuer of the Variable Contract or to the company servicing the Qualified Plan; and (2) make payments to the insurance company, broker-dealer or other financial intermediary. These payments may create a conflict of interest by: (1) influencing the insurance company or the company servicing the Qualified Plan to make the Portfolio available as an investment option for the Variable Contract or the Qualified Plan; or (2) by influencing the broker-dealer or other intermediary and your salesperson to recommend the Variable Contract or the pension servicing agent and/or the Portfolio over other options. Ask your salesperson or Qualified Plan administrator or visit your financial intermediary's website for more information.
