Strategy. The Portfolio pursues its investment objective by investing primarily in exchange-traded securities of other investment companies or investment vehicles (Underlying ETFs) and other instruments, including derivatives as described below, that provide exposure to global equity and fixed income markets. Under normal market conditions, the Sub-Adviser will allocate the Portfolios assets to achieve targeted exposures among equity investments and fixed income investments. The Portfolios current target allocation for long-term investments is approximately 60% of its net assets in equity investments and approximately 40% of its net assets in fixed income investments, through investments in Underlying ETFs and other instruments.

Under normal market conditions, the Sub-Adviser will allocate the Portfolios assets to achieve targeted exposures among equity investments and fixed income investments. The Portfolios current target allocation for long-term investments is approximately 60% of its net assets in equity investments and approximately 40% of its net assets in fixed income investments, through investments in Underlying ETFs and other instruments. On a periodic basis, the Sub-Adviser may rebalance the Portfolios investments in response to changes in market value or other factors to maintain these target allocations. During periods before or after such rebalancing, the Portfolio may deviate from its target allocations. The Portfolios equity allocation will be invested primarily in Underlying ETFs and other equity-related instruments, including derivatives as described below, that provide exposure to U.S. large, mid, and small cap stocks and foreign developed markets securities. The Portfolios current target is to invest approximately the following percentages of its net assets in Underlying ETFs and other equity-related instruments, including derivatives as described below, that provide exposure to the following equity asset categories: U.S. Large Cap Equity (25%), U.S. Mid Cap Equity (11.7%), U.S. Small Cap Equity (11.6%), and International Developed (11.7%). The allocations among the equity asset categories may be changed by the Sub-Adviser without notice or shareholder approval. The Sub-Adviser will periodically rebalance the Portfolios allocations among the equity asset categories to maintain the desired exposure to each asset category. The Portfolios allocations to different market capitalizations will vary based on the Sub-Advisers tactical views and in response to changing market conditions. The Underlying ETFs in which the Portfolio invests may be invested in securities denominated in any currency. Substantially all of the Portfolios fixed income allocation will be invested in the corporate debt asset category. The Portfolios fixed income allocation will be invested primarily in Underlying ETFs and other fixed income-related instruments, including derivatives as described below, to create a fixed income allocation with a risk and return profile similar to that of the Bloomberg U.S. 5-10 Year Corporate Bond Index, which is an unmanaged index that includes U.S. dollar-denominated, investment-grade, fixed-rate, taxable securities issued by industrial, utility and financial companies, with maturities between 5 and 10 years. An Underlying ETFs investments may include fixed coupon bonds, step-up bonds, bonds with sinking funds, medium term notes, callable and putable bonds, and 144A bonds. The Portfolio may also purchase or sell futures contracts on ETFs and enter into swap contracts in lieu of investing in Underlying ETFs themselves. The Sub-Adviser also will implement a volatility management strategy that seeks to reduce the Portfolios market risk exposure and overall volatility during periods of expected heightened market volatility. Volatility is a statistical measure of the magnitude of changes in the Portfolios returns. A higher volatility level 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 monitors the expected volatility of the Portfolio and the average expected volatility of the equity asset classes included within the Portfolio (U.S. Large Cap Equity, U.S. Mid Cap Equity, U.S. Small Cap Equity, and International Developed). When either of these two measures exceeds certain levels, as determined by the Sub-Adviser based on its volatility management strategy, the Portfolio may reduce its exposure to equity investments by shorting equity index futures or by investing up to 100% of its target equity allocation in cash or cash equivalents. During such times, the Portfolios overall exposure to equity investments may deviate significantly from its target allocation and could be substantially less than 60% of the Portfolios net assets (and could be 0% or a net short position in equity investments). 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. Although these actions are intended to reduce the overall risk of investing in the Portfolio, they may result in periods of underperformance, including during periods when market values are increasing, but market volatility is high. Under normal market conditions, the Portfolio seeks to maintain, over an extended period of years, an average annualized volatility in the Portfolios daily equity returns of not more than 20%. The magnitude of the changes (or volatility) in the Portfolios daily equity returns is measured by standard deviation. 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 may 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. In pursuing its investment objectives, the Portfolio may also 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 and options on futures contracts and indexes 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, 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. The Portfolio may engage in active and frequent trading of portfolio securities in pursuing its principal investment strategies. The Portfolio also may lend its portfolio securities to earn additional income. Show less
