NVIT iShares ETF Global Equity Fund

Objective And Strategy

Objective
The investment seeks long-term capital appreciation.

Strategy
The fund is a "fund-of-funds" that aims to provide diversification across traditional equity asset classes-large-cap, mid-cap and small-cap stocks issued by both U.S. and foreign issuers-by investing in a portfolio of unaffiliated ETFs sponsored by BlackRock Fund Advisors ("BFA") and which utilize a passive index-based strategy to track the performance of equity indexes. The fund invests, under normal circumstances, at least 80% of its net assets in equity securities through its investments in ETFs.

Principal Risks

* Fund of Funds Risks. The Portfolio is a "Fund of Funds" that invests in Underlying ETFs, which are typically open-end investment companies or unit investment trusts. By investing in securities of an Underlying ETF, the Portfolio shareholders will indirectly bear its proportionate share of any fees and expenses of the Underlying ETF in addition to the Portfolio's own fees and expenses. As a result, your cost of investing will be higher than the cost of investing directly in the Underlying ETFs and may be higher than mutual funds that invest directly in stocks and bonds. Also, the Fund may be prevented from fully allocating assets to a particular Underlying ETF due to fund-of funds investment limitations.

* ETF Risks. Underlying ETS are subject to the following risks: 1) the market price of an Underlying ETF's shares may trade above or below its net asset value; 2) an active trading market for an Underlying ETF's shares may not develop or be maintained; 3) the Underlying ETF may employ an investment strategy that utilizes high leverage ratios; 4) trading of an Underlying ETF's shares may be halted if the listing exchange's officials deem such action appropriate, the shares are delisted from the exchange or the activation of market wide "circuit breakers" (which are tied to large decreases in stock prices) halts stock trading generally; or 5) the Underlying ETF may fail to achieve close correlation with the index that it tracks due to a variety of factors, such as rounding of prices and changes to the index and/or regulatory policies, resulting in the deviating of the Underlying ETF's returns from that of its corresponding index. Some Underlying ETFs may be thinly traded, and the costs associated with respect to purchasing and selling the Underlying ETFs will be borne by the Portfolio.

* 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.

* This portfolio invests (or may invest) in securities of companies with micro-, small-, or mid-capitalization. Any investment in micro-, small-, or mid-capitalization companies involves greater risk than that customarily associated with investments in larger, more established companies because of the greater business risks of smaller size, limited markets and financial resources, narrower product lines, and frequent lack of management depth. As such, micro- or small-cap companies may be more subject to erratic and abrupt market movements than securities of larger, more established companies.

* This portfolio can leverage or use leveraged instruments or derivatives. Portfolios that use leverage, that is, borrow money, are subject to the risk that the cost of borrowing money to leverage will exceed the returns for the securities purchased or that the securities purchased may actually go down in value. Thus, the portfolio's net asset value can decrease more quickly than if the portfolio had not borrowed. Portfolios that use leveraged instruments or derivatives such as futures, options and swap agreements, may expose the portfolio to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. The more a portfolio invests in leveraged instruments, the more the leverage will magnify any gains or losses on those investments.

* 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.

* At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

* This Fund does not use defensive strategies or attempt to reduce its exposure to poorly performing stocks. Therefore, if the index performs poorly, the Fund, because it is correlated to the index, will perform poorly. Correlation between the Fund's performance and that of the index may also be negatively affected by the Fund's expenses, changes in the composition of the index, and the timing of purchase and redemption of Fund shares.

* A futures contract is considered a derivative because it derives its value from the price of the underlying security or financial index. The prices of futures contracts can be volatile, and futures contracts may be illiquid. In addition, there may be imperfect or even negative correlation between the price of a futures contract and the price of the underlying securities.

* The risk that the tax treatment of swap agreements and other derivative instruments, such as commodity-linked derivative instruments, including commodity index-linked notes, swap agreements, commodity options, futures, and options on futures, may be affected by future regulatory or legislative changes that could affect whether income from such investments is "qualifying income" under subchapter M of the Code.

* A repurchase agreement exposes the fixed income portion of the Portfolio to the risk that the party that sells the security may default on its obligation to repurchase the security. The Portfolio may lose money because it cannot sell the security at the agreed-upon time and price or the security may lose value before it can be sold.
