NVIT Strategic Income Fund: Class I

Objective And Strategy

Objective
The investment seeks to provide above average total return over a market cycle of three to five years.

Strategy
Under normal circumstances, the fund invests at least 80% of its net assets in different types of fixed-income securities, with few limitations as to credit quality, geography, maturity or sector, with the goal of achieving above average total return over a market cycle of three to five years. It may invest in U.S. government securities and foreign government bonds, as well as U.S. and foreign corporate bonds and debentures, asset-backed securities, mortgage-backed securities and convertible bonds.

Principal Risks

* This portfolio is subject to the risks of investing in low-grade corporate bonds that have a higher default risk, less liquidity and greater sensitivity to changes in the economy than investment-grade bonds. High-yield bonds are rated lower because there is a greater risk associated with the issuer's ability to pay principal and interest.

* This portfolio invests in securities of foreign issuers which involves risks not typically associated with domestic issuers, including currency fluctuations and the possibility of political and economic instability. Emerging markets involve risks in addition to those generally associated with foreign securities, because political and economic structures in many emerging markets may be undergoing significant evolution and rapid development.

* The portfolio's exposure to the US Dollar Index and/or foreign currencies subjects the portfolio to the risk that foreign currencies will fluctuate in value relative to the US Dollar or, in the case of short position, that the US Dollar will decline in value to the currency being hedged. Currency rates in foreign countries may move significantly over short periods of time for a number of reasons including changes in interest rates, the imposition of currency controls or other political developments in the US or abroad.

* The portfolio invests primarily in the securities of issuers that are organized and have their principal offices outside the United States.

* The Fund could lose money if the issuer of a debt security is unable to meet its financial obligations or goes bankrupt. This fund may invest in securities rated below investment grade or "junk bonds." Junk bonds may be sensitive to economic changes, political changes, or adverse developments specific to a company.

* This fund has a risk of prepayment and extension. A mortgage backed bond, unlike other bonds can be hurt when interest rates fall because homeowners refinance and prepay principal. Receiving increasing prepayments in a falling interest rate environment cause the average maturity of the portfolio to shorten, reducing its potential for price gains. It requires the fund to reinvest at lower interest rates, which reduced the portfolio's total return and yield, and may cause certain bond prices to fall below the level the fund paid for them, resulting in a capital loss.

* Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. A downgrade to an issuer's credit rating or a perceived change in an issuer's financial strength may affect a security's value, and thus, impact the VA Short-Term Fixed Portfolio's performance.

* During periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled, forcing the portfolio to reinvest in lower yielding securities.
