Fees and Expenses

Fees and Expenses of the Fund

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

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

Management Fee	0.35%
Distribution (12b-1) Fees	0.25%
Other Expenses	0.05%
Acquired Fund Fees and Expenses(1)	0.01%
Total Annual Fund Operating Expenses	0.66%

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated. The example also assumes that your investment has a 5% return each year, that the Fund's operating expenses remain the same, and that you reinvest all dividends and distributions. It does not reflect any Contract fees. If Contract fees were included, the costs shown would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$67	$211	$368	$822

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 105% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund generally invests in a combination of securities with an overall weighting close to the capitalization weights of the Bloomberg U.S. Aggregate Bond Index (the "Index"); however, the Fund's investments may not replicate the portfolio weights of the Index at all times. Instead, the Subadviser may overweight or underweight securities in the Fund (relative to

their weightings in the Index) in order to emphasize securities which have quantitative characteristics (such as above-average yield or below-average valuation) the Subadviser believes may enhance performance. The Fund may not invest in all of the bonds in the Index, or in the same weightings as in the Index. Because the Index typically includes securities not readily available in the market, the Fund may invest in bonds that are not included in the Index but that are selected to reflect as closely as practicable characteristics, such as maturity, duration, or credit quality, of bonds in the Index. This may result in different levels of interest rate, credit or other risks from the levels of risks on the securities included in the Index. The Fund may trade securities to the extent necessary to maintain the duration of certain segments of the portfolio close to the duration of corresponding segments of the Index. The Index is a broad-based benchmark that measures the investment grade, U.S. dollar-denominated, fixed-rate taxable bond market. The Index includes Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid ARM pass-throughs), asset-backed securities and commercial mortgage-backed securities (agency and non-agency).

Under normal market conditions, the Fund invests at least 80% of its net assets in investment-grade debt securities (those of medium and high quality) of all types and repurchase agreements for those securities. Further, under normal circumstances, the Fund invests at least 80% of the value of its net assets in securities or other financial instruments that are components of or have economic characteristics similar to the securities included in the Index. The Subadviser uses the Index as a guide in structuring the Fund and selecting its investments and manages the Fund to have similar overall interest rate risk to the Index, with the investment objective of seeking to exceed the total return of the Index.

The Fund usually will invest a portion of its assets in mortgage-backed securities. Most mortgage-backed securities are issued by Federal government agencies, such as the Government National Mortgage Association ("Ginnie Mae"), or government sponsored enterprises, such as the Federal Home Loan Mortgage Corporation ("Freddie Mac") or the Federal National Mortgage Association ("Fannie Mae"). Principal and interest payments on mortgage-backed securities issued by the Federal government agencies may be guaranteed by either the Federal government or the government agency, but not all such securities issued by certain government agencies and by government sponsored enterprises are guaranteed by the U.S. government or backed by the full faith and credit of the United States. The Fund may also invest up to 5% of its assets in collateralized loan obligations ("CLOs"), a type of asset-backed security. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans.

The Fund also may invest in U.S. Treasury bills, notes and bonds and other "full faith and credit" obligations of the U.S. Government. The Fund may also invest in U.S. Government agency securities, which are debt obligations issued or guaranteed by agencies or instrumentalities of the U.S. Government.

Securities must be rated investment grade or better at the time of purchase by at least one major rating agency or determined by the Fund's Subadviser to be of similar quality. Split rated bonds will be considered to have the higher credit rating. Except for Treasury or agency debentures, pass through securities, or REMICs (real estate mortgage investment conduits), no more than 3% of the Fund's assets may be invested in the securities of a single issuer.

The Fund may use futures, options, and/or swaps to manage duration and other characteristics of its portfolio. The Fund is permitted to purchase securities in private placements or Rule 144A transactions and to purchase securities on a when-issued basis or for forward delivery. The Fund may also enter into repurchase agreements and covered dollar rolls on mortgage securities. The Fund may invest in investment-grade debt securities of foreign issuers, including those located in emerging markets. The Fund may also invest in non-U.S. dollar denominated securities, but when it does, the Subadviser typically will hedge the foreign currency exposure to the U.S. dollar through the use of currency forwards or cash. The Fund's investments in emerging market debt will be U.S. dollar denominated.

The Fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies.

Principal Risks of Investing in the Fund

The price per share of the Fund will fluctuate with changes in the value of the investments held by the Fund. You may lose money by investing in the Fund. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. There is no guarantee that the Fund will achieve its objective.

The following is a summary of the principal risks to which the Fund's portfolio as a whole is subject, any of which may adversely affect the Fund's net asset value (NAV), yield, total return and ability to achieve its investment objective. As changes occur in a Fund's portfolio holdings, the extent to which the portfolio is subject to each of these risks may also change.

Market Risk - The market value of portfolio securities may go up or down, sometimes rapidly and unpredictably.

Issuer Risk - The value of a security may decline for a number of reasons directly related to the issuer of the security.

Selection Risk - Because this Fund is actively managed, there can be no guarantee that investment decisions made for the Fund will produce the desired results. Although the Fund seeks to provide a total return in excess of the Index, market conditions or implementation of the Fund's investment strategy may result in losses, and the Fund may not achieve the desired correlation with and/or may not outperform the Index.

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

Treasury Obligations Risk - Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of a fund. Because U.S. Treasury obligations trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. In addition, changes in the credit rating or financial condition of the U.S. government may cause the value of U.S. Treasury Obligations to decline.

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

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

Income Risk - Falling interest rates may cause a fund's income to decline.

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

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

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

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

Liquidity Risk - An investment that is difficult to purchase or sell may have an adverse effect on the fund's returns.

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

Derivatives Risk - Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments. Derivatives are subject to a number of other risks, such as liquidity risk, interest rate risk, market risk, credit risk, counterparty risk, and selection risk. Derivatives also

involve the risk of mispricing or improper valuation and the risk that changes in the value may not correlate perfectly with the underlying asset, rate, or index. Using derivatives may result in losses, possibly in excess of the principal amount invested.

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

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

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

Portfolio Turnover Risk - The Fund may trade portfolio securities frequently, which could result in higher transaction costs and could adversely affect the fund's performance.

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

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

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

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

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

Tax Information

Shares of the Funds are sold exclusively to the separate accounts of certain insurance companies in connection with particular variable annuity and variable life insurance contracts (the "Contracts"). Provided that a Fund and a separate account investing in the Fund satisfy applicable tax requirements, any distributions from the Fund to the separate account will be exempt from current federal income taxation to the extent that such distributions accumulate in the Contract. You should refer to your Contract prospectus for further information regarding the tax treatment of the Contract and the separate accounts in which the Contract is invested.

Financial Intermediary Compensation

Shares of the Funds are sold exclusively to certain insurance companies in connection with particular Contracts. The Trust and its related companies may pay such insurance companies (or their related companies) for the sale of shares of the Funds and related services. Such insurance companies (or their related companies) may pay broker-dealers or other financial intermediaries (such as banks) that sell the Contracts for the sale of shares of the Funds and related services. When received by an insurance company, such payments may be a factor that the insurance companies consider in including a Fund as an investment option in the Contracts. The prospectus or other disclosures relating to a Contract may contain additional information about these payments. When received by a broker-dealer or other intermediary, such payments may create a conflict of interest by influencing the broker-dealer or other intermediary and salespersons to recommend the Fund over other mutual funds available as investment options in the Contracts. Ask the salesperson or visit the financial intermediary's website for more information.
