Wilshire manages the Capital Appreciation and Income Component pursuant to a "fund of funds" strategy that seeks to achieve its objective by investing in a combination of certain mutual funds in the American Funds Insurance Series ? and other American Funds ? (the "Underlying Funds"), offered through different prospectuses. This strategy of investing in a combination of Underlying Funds is intended to result in investment diversification that an investor could otherwise achieve only by holding numerous individual investments. Milliman manages the Managed Risk Component pursuant to a strategy that seeks to manage portfolio volatility and provide downside risk management. The Adviser seeks to achieve the Portfolio's investment objective by allocating, under normal circumstances, at least 80% of the Portfolio's net assets, plus any borrowings for investment purposes, to the Capital Appreciation and Income Component and up to 20% of the Portfolio's net assets to the Managed Risk Component. Wilshire expects to further allocate approximately 65% of the Portfolio's Capital Appreciation and Income Component to Underlying Funds that hold primarily equity securities and 35% to Underlying Funds that hold primarily fixed-income securities, although Wilshire may modify the target allocation from time to time. Wilshire utilizes both qualitative and quantitative components to develop the target allocations. The process seeks to generate target allocations that integrate Wilshire's macroeconomic views, strategy insights, and robust analytics to develop a portfolio that is designed to perform in a variety of market environments. The Portfolio will include, but is not limited to, Underlying Funds that also employ an active investment style. The equity Underlying Funds typically invest in core, growth and value equity securities of U.S. and foreign medium and large capitalization issuers, but may also invest in small capitalization companies and derivatives. The fixed-income Underlying Funds typically invest in domestic fixed-income securities including, but not limited to, U.S. Treasury securities, sovereign debt securities, corporate bonds, mortgage-backed securities and inflation-indexed securities, as well as derivatives. In addition, the Underlying Funds may invest in debt assets in lower quality debt securities (rated Ba1 or below and BB+ or below by Nationally Recognized Statistical Rating Organizations designated by the Underlying Funds' adviser or unrated but determined to be of equivalent quality by the Underlying Funds' adviser). Such securities are sometimes referred to as "junk bonds." Wilshire generally intends to rebalance the Portfolio on a quarterly basis or as needed, to align more closely with target allocations. The target allocations are subject to change through dynamic tilts (a percentage overweight or underweight relative to long-term strategic asset allocation targets) that emphasize asset classes and strategies that appear attractive and undervalued and de-emphasize asset classes and strategies that appear less attractive. Under normal conditions, dynamic tilts are reflected in Wilshire's quarterly target allocations, but Wilshire will make ad-hoc changes intra-quarter if its dynamic views deem them appropriate. The basis for such dynamic tilts is developed in Wilshire's Investment Strategy Committee, which is comprised of senior investment professionals across Wilshire's investment team. In the Managed Risk Component, the Adviser seeks to manage return volatility by employing Milliman to execute a managed risk strategy, which consists of using hedge instruments to reduce the downside risk of the Portfolio's securities. Milliman may use hedge instruments to accomplish this goal, which may include: equity futures contracts, treasury futures contracts, currency futures contracts, and other hedge instruments judged by Milliman to be necessary to achieve the goals of the managed risk strategy. Milliman may also buy or sell hedge instruments based on one or more market indices in an attempt to maintain the Portfolio's volatility at the targeted level in an environment in which Milliman expects market volatility to decrease or increase, respectively. Milliman selects individual hedge instruments that it believes will have prices that are highly correlated to the Portfolio's positions. Milliman adjusts hedge instruments to manage overall net Portfolio risk exposure, in an attempt to stabilize the volatility of the Portfolio around a predetermined target level and reduce the potential for portfolio losses during periods of significant and sustained market decline. Milliman seeks to monitor and forecast volatility in the markets using a proprietary model, and adjust the Portfolio's hedge instruments accordingly. In addition, Milliman will monitor liquidity levels of relevant hedge instruments and transparency provided by exchanges or counterparties in hedging transactions. Milliman adjusts futures positions to manage overall net Portfolio risk exposure. Milliman may, during periods of rising security prices, implement strategies to preserve gains on the Portfolio's positions. Milliman may, during periods of falling security prices, implement additional strategies to reduce losses in adverse market conditions. In these situations, Milliman's activity could significantly reduce the Portfolio's net economic exposure to equity securities. Following market declines, a downside rebalancing strategy will be used to decrease the amount of hedge instruments used to hedge the Portfolio. Milliman also adjusts hedge instruments to realign individual hedges when the Adviser rebalances the Capital Appreciation and Income Component of the Portfolio's asset allocation profile. Depending on market conditions, scenarios may occur where the Portfolio has no positions in any hedge instruments. Show less
