The following table describes the fees and expenses that you may pay if you buy and hold shares of the Portfolio. The table below does not reflect any fees and expenses associated with variable life insurance contracts and variable annuity certificates and contracts (“Contracts”), which would increase overall fees and expenses. See the Contract prospectus for a description of those fees and expenses.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 32% of the average value of the Portfolio.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other portfolios. The example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those time periods. The example also assumes that your investment has a 5% return each year, that the Portfolio’s operating expenses (and expenses of other investment companies in which it invests) remain the same and that the expense limitation arrangement is not renewed. This example does not reflect any Contract-related fees and expenses, including redemption fees (if any) at the Contract level. If such fees and expenses were reflected, the total expenses would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Portfolio seeks to achieve its objective by investing in other mutual funds (the "Underlying Portfolios") managed by AXA Equitable Funds Management Group, LLC ("FMG LLC" or "Manager"), which represent a variety of asset classes and investment styles. The Portfolio is managed to target 2015 as the specific year of planned retirement (the "retirement year"). The retirement year also assumes that an investor retires at age 65. The Portfolio's asset mix will become more conservative each year until reaching the year approximately ten years after the retirement year (the "target year") at which time the asset mix will become relatively static. The asset classes in which the Portfolio may invest generally are divided into domestic equity, international equity and fixed income investments. The following chart shows the Portfolio's target allocation for the various asset classes (as represented by the holdings of the Underlying Portfolios in which the Portfolio invests) as of the date of this Prospectus.

Target 2015 Allocation Portfolio Asset Allocations


Approximate Number of Years Before/After Retirement	3 Years Before		Retirement		5 Years After		10 Years After
Asset Class
Domestic Equity		41%		35%		30%		15%
International Equity		18%		15%		10%		5%
Fixed Income
(including domestic and foreign investment grade and high yield or "junk" bonds, and short term investments such as money market instruments)		41%		50%		60%		80%

The following chart illustrates how the asset mix of the Portfolio will vary over time. In general, the asset mix of the Portfolio will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that increasingly favors Underlying Portfolios that emphasize investments in bonds and money market instruments.

	Domestic Equity	International Equity	Investment Grade	High Yield	Short Term
	--------	--------------	----------------	-----------	-----------
40	67.00%	33.00%	0.00%	0.00%	0.00%

10	13.25%	6.75%	41.00%	10.00%	29.00%

As of December 31, 2011, the Portfolio's asset mix was approximately 39.4% to domestic equity, 21.1% to international equity, and 39.5% to fixed income (fixed income allocations may include domestic and foreign investment grade bonds and high yield or "junk" bonds as well as short term investments such as money market instruments).The Portfolio's Annual and semi-Annual Reports to shareholders set forth the actual allocation to the Underlying Portfolios as of the date of the report.

The Manager establishes the asset mix of the Portfolio and selects the specific Underlying Portfolios in which to invest using its proprietary investment process, which is based on fundamental research regarding the investment characteristics of each asset class and the Underlying Portfolios, as well as its outlook for the economy and financial markets. The Manager may change the asset allocation targets and may add new Underlying Portfolios or replace or eliminate existing Underlying Portfolios without notice or shareholder approval.. The Manager may sell the Portfolio's holdings for a variety of reasons, including to invest in an Underlying Portfolio believed to offer superior investment opportunities.

The Manager will permit the relative weightings of the Portfolio's asset classes to vary in response to the markets, but ordinarily only by plus/minus 15%. Beyond those ranges, the Manager generally will use cash flows, and periodically will rebalance, to keep the Portfolio within its asset allocation targets. However, there may be occasions when those ranges will expand to 20% due to a variety of factors, including appreciation or depreciation of one or more of the asset classes. The Portfolio will purchase Class K shares of the Underlying Portfolios, which are not subject to distribution or service (Rule 12b-1) fees.

The Underlying Portfolios may already be available directly as an investment option in your Contract and an investor in the Portfolio bears both the expenses of the Portfolio as well as the indirect expenses associated with the Underlying Portfolios. Therefore, you may be able to realize lower aggregate expenses by investing directly in the Underlying Portfolios of a Portfolio instead of in the Portfolio itself. However, not all of the Underlying Portfolios may be available as an investment option in your Contract. In addition, an investor who chooses to invest directly in the Underlying Portfolios would not receive the asset allocation and rebalancing services provided by the Manager.

The Principal Risks of Investing in the Portfolio

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

An investment in the Portfolio is not a deposit of a bank and is not insured by the Federal Deposit Insurance Corporation or any other government agency. You may lose money by investing in the Portfolio. Performance may be affected by one or more of the following risks.

Affiliated Portfolio Risk — In managing a portfolio that invests in Underlying Portfolios, the Manager will have the authority to select and substitute the Underlying Portfolios. The Manager may be subject to potential conflicts of interest in allocating the portfolio’s assets among the various Underlying Portfolios because the fees payable to it by some of the Underlying Portfolios are higher than the fees payable by other Underlying Portfolios and because the Manager is also responsible for managing, administering, and with respect to certain Underlying Portfolios, its affiliates are responsible for sub-advising, the Underlying Portfolios.

Credit Risk — The risk that the issuer or the guarantor of a fixed income security, or the counterparty to a derivatives contract, repurchase agreement, loan of portfolio securities or other transaction, is unable or unwilling, or is perceived (whether by market participants, ratings agencies, pricing services or otherwise) as unable or unwilling, to make timely principal and/or interest payments, or otherwise honor its obligations. Securities are subject to varying degrees of credit risk, which are often reflected in their credit ratings. Securities rated below investment grade (e.g., “junk bonds”) may include a substantial risk of default.

Equity Risk — In general, stocks and other equity security values fluctuate, and sometimes widely fluctuate, in response to changes in a company’s financial condition as well as general market, economic, and political conditions.

Foreign Securities Risk — Investments in foreign securities, including depositary receipts, involve risks not associated with investing in U.S. securities. Foreign markets, particularly emerging markets, may be less liquid, more volatile and subject to less government supervision than domestic markets. Security values also may be negatively affected by changes in the exchange rates between the U.S. dollar and foreign currencies. Differences between U.S. and foreign legal, political and economic systems, regulatory regimes and market practices also may impact security values and it may take more time to clear and settle trades involving foreign securities.

Interest Rate Risk — The risk that fixed income securities will decline in value because of changes in interest rates. When interest rates decline, the value of a portfolio’s debt securities generally rises. Conversely, when interest rates rise, the value of a portfolio’s debt securities generally declines. A portfolio with a longer average duration will be more sensitive to changes in interest rates than a fund with a shorter average duration.

Investment Grade Securities Risk — Debt securities are rated by national bond ratings agencies. Securities rated BBB or higher by Standard & Poor’s Ratings Services (“S&P”) or Fitch Ratings, Ltd. (“Fitch”) or Baa or higher by Moody’s Investors Service, Inc. (“Moody’s”) are considered investment grade securities, but are somewhat riskier than higher rated obligations because they are regarded as having only an adequate capacity to pay principal and interest, and are considered to lack outstanding investment characteristics.

Junk Bonds or Lower Rated Securities Risk — Bonds rated below investment grade (i.e., BB by S&P or Fitch or Ba by Moody’s) are speculative in nature and are subject to additional risk factors such as increased possibility of default, illiquidity of the security, and changes in value based on changes in interest rates. “Junk bonds” are usually issued by companies without long track records of sales and earnings, or by those companies with questionable credit strength.

Large-Cap Company Risk — Larger more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Many larger companies also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

Market Risk — The risk that the securities markets will move down, sometimes rapidly and unpredictably based on overall economic conditions and other factors.

Mid-Cap and Small-Cap Company Risk — A portfolio’s investments in mid- and small-cap companies may involve greater risks than investments in larger, more established issuers because they generally are more vulnerable than larger companies to adverse business or economic developments. Such companies generally have narrower product lines, more limited financial resources and more limited markets for their stock as compared with larger companies. As a result, the value of such securities may be more volatile than the securities of larger companies, and the portfolio may experience difficulty in purchasing or selling such securities at the desired time and price or in the desired amount. In general, these risks are greater for small-cap companies than for mid-cap companies.

Portfolio Management Risk — The risk that strategies used by the Manager or the investment sub-adviser (“Adviser”) and their securities selections fail to produce the intended results.

Risks of Investing in Other Investment Companies — Investors in a portfolio that invests in Underlying Portfolios will indirectly bear fees and expenses charged by those Underlying Portfolios, in addition to the Portfolio’s direct fees and expenses. The cost of investing in the Portfolio, therefore, may be higher than the cost of investing in a mutual fund that invests directly in individual stocks and bonds. In addition, the Portfolio’s net asset value is subject to fluctuations in the net asset value of each Underlying Portfolio. The Portfolio is also subject to the risks associated with the securities in which the Underlying Portfolios invest and the ability of the Portfolio to meet its investment objective will depend, to a significant degree, on the ability of the Underlying Portfolios to meet their objectives. The Portfolio and the Underlying Portfolios are subject to certain general investment risks, including market risk, issuer-specific risk, investment style risk and portfolio management risk. In addition, to the extent a Portfolio invests in Underlying Portfolios that invest in equity securities, fixed income securities and/or foreign securities, the Portfolio is subject to the risks associated with investing in such securities. The Underlying Portfolios may change their investment objectives or policies without the approval of the Portfolio. If that were to occur, the Portfolio might be forced to withdraw its investment from the Underlying Portfolio at a time that is unfavorable to the Portfolio.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The bar chart and table below provide some indication of the risks of investing in the Portfolio by showing changes in the Portfolio’s performance from year to year and by showing how the Portfolio’s average annual total returns for the past year and since inception through December 31, 2011 compare to the returns of a broad-based market index. The additional broad-based market indexes show how the Portfolio’s performance compares with the returns of other asset classes in which the Portfolio may invest. Past performance is not necessarily an indication of future performance.

The Class K shares commenced operations on December 1, 2011. The performance information shown in the table below for the Class K shares prior to that date is the performance of the Class A shares, which would have annual returns identical to those of the Class K shares because the Class A shares are invested in the same portfolio of securities and, prior to January 1, 2012, had the same expenses as the Class K shares.

Class A shares are not currently operational. Class A share performance information shown in the table below is the performance of Class B shares, which reflects the effect of Rule 12b-1 fees paid by Class B shares.

The performance results do not reflect any Contract-related fees and expenses, which would reduce the performance results.
