Under normal circumstances, the Sub-Adviser will invest in a combination of individual securities, exchange-traded funds (ETFs) and futures contracts that provide exposure to global equity markets, including large, mid- and small-cap stocks, and U.S. Treasuries. The Sub-Adviser targets an equity allocation of approximately 50% of its assets in U.S. and foreign large, mid and small cap stocks, as well as ETFs and futures contracts that provide exposure to such stocks. The Sub-Adviser weights each of the equity categories (Large Cap US, Mid Cap US, Small Cap US, and International Developed) according to the relative market capitalization of each category. The Sub-Adviser rebalances the equity portfolio as necessary to maintain weighting in proportion to market capitalization. To gain exposure to each equity category, the Sub-Adviser generally will invest the Portfolios assets in equity securities and other instruments in a manner that is intended to track the performance (before fees and expenses) of an unmanaged index selected by the Sub-Adviser that measures the equity market performance of the equity category. Securities in which the Portfolio may invest may be denominated in any currency. The Sub-Adviser targets a fixed-income allocation of approximately 50% of its assets in baskets of U.S. Treasuries, U.S. interest rate futures contracts, and ETFs to create a fixed income allocation with a risk and return profile similar to that of the Bloomberg U.S. Intermediate Government Bond Index, which is an unmanaged index consisting of all U.S. Treasury and agency securities with remaining maturities of one to ten years. On a periodic basis, the Sub-Adviser may rebalance the Portfolios equity and fixed income investments in response to changes in market value or other factors to maintain its target allocations. During periods before or after such rebalancing, the Portfolio may deviate from its target allocations. The Sub-Adviser also will implement a volatility management strategy that seeks to manage the volatility level of the Portfolios annual returns. Volatility is a statistical measure of the magnitude of changes in the Portfolios returns. Higher volatility generally indicates higher risk and often results in more frequent and sometimes significant changes in the Portfolios returns. To implement this volatility management strategy, the Sub-Adviser will monitor forecasted annualized volatility of the Portfolios returns, placing a greater weight on recent historic data. During periods of heightened forecasted volatility, the Sub-Adviser will attempt to lower volatility by closing existing long exchange-traded equity index futures contracts, selling equity exposures that are derived using ETFs or, in the case where physical securities are held, selling physical securities, or selling exchange-traded equity index futures contracts, in the effort to target a certain level of maximum annual volatility as determined by the Sub-Adviser based on its volatility management strategy. The Sub-Adviser may use these methods as often as daily to lower the Portfolios expected volatility level. During such times, the Portfolios overall exposure to equity investments may deviate significantly from its target allocation and could be substantially less than 50% of the Portfolios assets (and could be 0%). In addition, over time the use of a volatility management strategy could result in the Portfolios having average exposure to equity investments that is lower than its target allocation. Due to market conditions or other factors, the actual or realized volatility of the Portfolio for any particular period of time may be materially higher or lower than the target maximum annual level. Although these actions are intended to reduce the overall risk of investing in the Portfolio, they could result in periods of underperformance, including during periods when market values are increasing, but market volatility is high. The Sub-Adviser may determine, in its sole discretion, not to implement the volatility management strategy or to allocate the Portfolios assets in a manner different than the target allocations described above for various reasons including, but not limited to, if the volatility management strategy would result in de minimis trades or result in excess trading due to expected flows into or out of the Portfolio, or in connection with market events and conditions and other circumstances as determined by the Sub-Adviser. Volatility management techniques could reduce potential losses and/or mitigate financial risks to insurance companies that provide certain benefits and guarantees available under the Contracts and offer the Portfolio as an investment option in their products. Accordingly, volatility management techniques could also benefit the insurance companies by reducing the risk that the insurance companies will be required to pay amounts to meet the benefits and guarantees from their own resources. In pursuing its investment objective, the Portfolio may invest in derivatives for the efficient management of the Portfolio (including to enhance returns), to implement the volatility management strategy, or for the hedging of certain market risks. It is anticipated that the Portfolios derivative instruments will consist of long and short positions on exchange-traded equity and fixed income futures contracts as well as currency forwards. The Portfolio also may utilize other types of derivatives, such as swaps, and may engage in short sales. The Portfolios investments in derivatives may be deemed to involve the use of leverage because the Portfolio is not required to invest the full market value of the contract upon entering into the contract but participates in gains and losses on the full contract price. The use of derivatives also may be deemed to involve the use of leverage because the heightened price sensitivity of some derivatives to market changes may magnify the Portfolios gain or loss. It is not generally expected, however, that the Portfolio will be leveraged by borrowing money for investment purposes. From time to time or potentially for extended periods of time in periods of continued market distress, the Portfolio may maintain a considerable percentage of its total assets in cash and cash equivalent instruments, including money market funds which may be affiliated with the Sub-Adviser, as margin or collateral for the Portfolios obligations under derivative transactions, to implement the volatility management strategy, and for other portfolio management purposes. The larger the value of the Portfolios derivative positions, as opposed to positions held in non-derivative instruments, the more the Portfolio will be required to maintain cash and cash equivalents as margin or collateral for such derivatives.
