Strategy. The Portfolios asset allocation generally provides for an allotment of approximately 75% of Portfolio assets to a combination of domestic and international equity strategies and an allotment of approximately 25% of Portfolio assets to a combination of US fixed income, global hedged bond, and emerging market bond investment strategies. To achieve its investment strategies, the Portfolio may invest in other pooled investment vehicles (collectively referred to as underlying portfolios). The asset allocation strategy is determined by the Manager and PGIM Quantitative Solutions LLC (PGIM Quantitative Solutions), the subadviser to the Portfolio.

To achieve its investment strategies, the Portfolio may invest in other pooled investment vehicles (collectively referred to as underlying portfolios). The asset allocation strategy is determined by the Manager and PGIM Quantitative Solutions LLC (PGIM Quantitative Solutions), the subadviser to the Portfolio. As a general matter, PGIM Quantitative Solutions begins by constructing a neutral allocation for the Portfolio. Each neutral allocation initially divides the assets for the Portfolio across three broad-based securities benchmark indexes. These three benchmark indexes are the Russell 3000 Index, the MSCI Europe, Australasia and the Far East (EAFE) Index, and the Bloomberg US Aggregate Bond Index. The neutral allocation will emphasize investments in the equity asset class. The selection of specific combinations of underlying Portfolios for the Portfolio generally will be determined by the Manager. The Manager will employ various quantitative and qualitative research methods to establish weighted combinations of underlying Portfolios that are consistent with the neutral allocation for the Portfolio. PGIM Quantitative Solutions will then perform its own forward-looking assessment of macroeconomic, market, financial, security valuation, and other factors. As a result of this assessment, PGIM Quantitative Solutions will further adjust the neutral allocation and the preliminary underlying Portfolio weights for the Portfolio based upon its views on certain factors. The Portfolio may invest in other pooled investment vehicles, including other portfolios of the Trust, other open-end or closed-end investment companies, and both active and passive exchange-traded funds (ETFs), unit investment trusts, and domestic or foreign private investment pools (including investment companies not registered under the 1940 Act, such as hedge funds) (collectively referred to as underlying portfolios). In addition to the Portfolio's investment in those underlying pooled portfolios, the Portfolio may also invest its assets in the AST PGIM Fixed Income Central Portfolio (the PGIM Central Portfolio). The PGIM Central Portfolio is a special type of investment vehicle for sole use by certain asset allocation portfolios, including the Portfolio. The PGIM Central Portfolio normally invests at least 80% of its assets (net assets plus any borrowings made for investment purposes) in investment grade bonds. Rather than buy bonds directly, the Portfolio may invest in the PGIM Central Portfolio. The Portfolio may invest without limit in the PGIM Central Portfolio. The remainder of the Portfolio's assets will be managed directly by subadvisers to the Portfolio. Those percentages and allocations are subject to change by the Manager and PGIM Quantitative Solutions. Included in the directly managed portion is an overlay strategy managed by PGIM Quantitative Solutions for liquidity and asset allocation purposes. The Portfolio allocates approximately 15-25% of its net assets to the overlay strategy, which is employed through an overlay sleeve. The overlay strategy seeks to allow for the efficient management of Portfolio-level risk and changes in the Portfolios asset levels, liquidity, and asset allocations. The overlay strategy is also used to access and adjust exposures to various asset classes and underlying strategy allocations. The overlay strategy is invested primarily in (i) derivative instruments including, but not limited to, swaps, forwards, index futures, other futures contracts, and options thereon to provide liquid exposure to the applicable equity and fixed income benchmark indices; and (ii) cash, money market equivalents, short-term debt instruments, money market funds, and short-term debt funds to satisfy all applicable margin requirements for the futures contracts and to provide additional portfolio liquidity to satisfy large-scale redemptions. The overlay strategy may also invest in ETFs for additional exposure to relevant markets. The overlay strategy may temporarily deviate from the allocation indicated due to redemptions in the Portfolio or other circumstances relevant to the Portfolios overall investment process. Show less
