Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a falsefalseInvestment Strategy, Heading20false0rr_StrategyNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<pre>Under normal circumstances, the Fund invests primarily in equity securities of publicly-traded companies located anywhere in the world, including equity securities in developed and emerging markets. Under normal market conditions, the Fund expects to invest at least 40% of its assets in non-U.S. companies. In making investment decisions for the Fund, Sands Capital Management, LLC (the "Adviser") focuses on companies that generate (or that the Adviser expects to generate) above average earnings growth and that, in the Adviser's opinion, are leading growth businesses in the marketplace. The Fund typically invests in a portfolio of 30-50 issuers that the Adviser believes represents the best opportunities to achieve the Fund's investment objective. In selecting securities for the Fund, the Adviser utilizes a fundamental, bottom-up, business-focused research approach. This research starts with internal competitive landscape analysis, ongoing participation at industry conferences, review of industry and trade periodicals and quantitative screens to populate an initial universe of publicly traded companies that it expects will generate above average earnings growth. The Adviser then evaluates each company for six key investment criteria: o sustainable above-average earnings growth; o leadership position in a promising business space; o significant competitive advantages; o clear mission and value-added focus; o financial strength; and o rational valuation relative to the market and business prospects. Companies that the Adviser determines may meet all six investment criteria are then screened with in-depth qualitative and quantitative research, including a full competitive analysis and proprietary financial modeling. This additional screening also typically includes identifying the key metrics for a particular business or industry, any specific risks or issues relating to a company, as well as a hypothetical "sell case," i.e. evaluating a range of scenarios under which a position in a security would be reduced or sold. The Fund intends to buy and hold securities for the long term and seeks to maintain a low level of portfolio turnover. The portfolio turnover rate of the Fund is expected to be below 50% of the average value of its portfolio. The Adviser employs a sell discipline in which the security of a company is sold if an issue emerges that negatively impacts the Adviser's assessment of one or more of the six investment criteria discussed above and the Adviser believes that the issue cannot be resolved within an acceptable time frame. The Adviser may also sell a holding if it becomes materially overvalued versus its underlying business, for risk management purposes, and/or if a more attractive investment opportunity presents itself. While the Fund may invest in equity securities of companies of any size, the Fund will primarily invest in large and mid-capitalization companies given the Adviser's focus on what it considers to be established business "leaders." As such, the Fund will generally not invest in companies with a market capitalization of less than $2 billion and its total median market capitalization will typically be significantly greater than that of the MSCI Barra's ("MSCI") MSCI All Country World Index, the Fund's benchmark. As of December 31, 2010, the total median market capitalization of the MSCI All Country World Index was $7.2 billion. The equity securities in which the Fund invests include common stocks as well as preferred securities. The Fund may also purchase American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs") and Global Depositary Receipts ("GDRs" and, together with ADRs and EDRs, "Depositary Receipts"), which are certificates typically issued by a bank or trust company that represent securities issued by a foreign or domestic company. From time to time, the Fund may have significant investments in one or more countries. The Fund may invest up to the greater of 30% of its net assets or three times the emerging markets component of the MSCI All Country World Index, in securities of companies located in emerging markets. As of December 31, 2010, the emerging markets component of the MSCI All Country World Index was 14% of the total Index. The Fund may also invest in derivatives, specifically "market access products," to gain economic exposure to markets where holding an underlying security is not feasible. A market access product is a derivative security that provides market exposure to an underlying foreign issuer. Examples of market access products are low exercise price options ("LEPOs") and participatory notes ("P-notes"), both of which allow the holder to gain exposure to issuers in certain countries. A LEPO is an option to purchase a security with an exercise price significantly below the market price of the underlying security. Because of its low exercise price, a LEPO is virtually certain to be exercised and the value and performance of its intrinsic value is effectively identical to that of the underlying equity. These features are designed to allow participation in the performance of an equity security where there are legal or financial obstacles to purchasing the underlying security directly. If the LEPO is cash-settled, the buyer profits to the same extent as with a direct holding in the underlying, but without having to transact in it. P-notes are derivatives that are generally traded over the counter and constitute general unsecured contractual obligations of the banks and broker-dealers that issue them. Generally, these banks and broker-dealers buy securities listed on certain foreign exchanges and then issue P-notes which are designed to replicate the performance of certain issuers and markets. The Fund's investments in derivatives are limited to market access products and only for the purpose of gaining exposure to an underlying long equity position. The Fund may invest up to 20% of its net assets in these derivatives.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

A FUND SHARE IS NOT A BANK DEPOSIT AND IT IS NOT INSURED OR GUARANTEED BY THE FDIC OR ANY GOVERNMENT AGENCY. The principal risk factors affecting shareholders' investments in the Fund are set forth below. Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund's equity securities may fluctuate drastically from day-to-day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund. Investing in foreign companies, including direct investments and through Depositary Receipts, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign companies are generally denominated in a foreign currency, the value of which may be influenced by currency exchange rates and exchange control regulations. Changes in the value of a currency compared to the U.S. dollar may affect (positively or negatively) the value of the Fund's investments. These currency movements may occur separately from, and in response to, events that do not otherwise affect the value of the security in the issuer's home country. While Depositary Receipts provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in Depositary Receipts continue to be subject to many of the risks associated with investing directly in foreign securities. The Fund may invest in companies located or doing business in emerging market countries. An "emerging market" country is any country determined by the Adviser to have an emerging market economy, considering factors such as the country's credit rating, its political and economic stability and the development of its financial and capital markets. Typically, emerging markets are in countries that are in the process of industrialization, with lower gross national products than more developed countries. For purposes of determining whether a particular country is considered a developed market or an emerging market, the Fund uses the designation set forth by the MSCI, a prominent provider of investment tools and data services for institutions worldwide. Investments in emerging markets securities are considered speculative and subject to heightened risks in addition to the general risks of investing in non-U.S. securities. Unlike more established markets, emerging markets may have governments that are less stable, markets that are less liquid and economies that are less developed. Differences in tax and accounting standards and difficulties in obtaining information about foreign governments or foreign companies may impair investment decisions. In addition, emerging markets securities may be subject to smaller market capitalization of securities markets, which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. Furthermore, emerging markets governments may have limited ability to raise taxes or authorize appropriations for debt repayment. In addition, foreign investors may be required to register the proceeds of sales, and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. Moreover, the currencies of emerging market countries may experience significant declines against the U.S. dollar, and devaluation may occur subsequent to investments in these currencies by the Fund. Inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and securities markets of certain emerging market countries. The Fund may incur operating expenses that are higher than those of mutual funds that invest exclusively in U.S. equity securities due to higher custodial fees and brokerage commissions associated with investments in foreign securities. These risks may be magnified in less-established, emerging markets. The large capitalization companies in which the Fund may invest may lag the performance of smaller capitalization companies because large capitalization companies may experience slower rates of growth than smaller capitalization companies and may not respond as quickly to market changes and opportunities. The mid-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, these mid-sized companies may pose additional risks, including liquidity risk, because these companies tend to have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, mid-cap stocks may be more volatile than those of larger companies. The Fund pursues a "growth style" of investing, meaning that the Fund invests in equity securities of companies that the Adviser believes will increase their earnings at a certain rate that is generally higher than the rate expected for non-growth companies. If a growth company does not meet these expectations, the price of its stock may decline significantly, even if it has increased earnings. Many growth companies do not pay dividends. Companies that pay dividends often have lower stock price declines during market downturns. Over time, a growth investing style may go in and out of favor, causing the Fund to sometimes underperform other equity funds that use differing investing styles. The Fund may also invest in derivatives, specifically "market access products," to gain economic exposure to markets where holding an underlying security is not feasible. A market access product is a derivative security that provides market exposure to an underlying foreign issuer. Derivatives are often more volatile than other investments and may magnify the Fund's gains or losses. There are various factors that affect the Fund's ability to achieve its investment objective with derivatives. Successful use of a derivative depends upon the degree to which prices of the underlying assets correlate with price movements in the derivatives the Fund buys or sells. The Fund could be negatively affected if the change in market value of its securities fails to correlate perfectly with the values of the derivatives it purchased or sold. The lack of a liquid secondary market for a derivative may prevent the Fund from closing its derivative positions and could adversely impact its ability to achieve its investment objective or to realize profits or limit losses. Because derivative instruments may be purchased by the Fund for a fraction of the market value of the investments underlying such instruments, a relatively small price movement in the underlying investment may result in an immediate and substantial gain or loss to the Fund. Derivatives are often more volatile than other investments and the Fund may lose more in a derivative than it originally invested in it. Additionally, derivative instruments, particularly market access products, are subject to counterparty risk, meaning that the party that issues the derivative may experience a significant credit event and may be unwilling or unable to make timely settlement payments or otherwise honor its obligations.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Provide a statement to the effect that the Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph i -Subsection b Reference 2: 2 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph instructions -Clause 1 -Exhibit b -Subsection b falsefalsePerformance, One Year or Less28false0natruenanaNo definition available.falsetruefalsefalsefalsefalsefalsefalsefalsefalsehttp://www.acadian-asset.com/role/riskreturndetaildata_s000028356member21falsefalsefalse00falsefalsefalsefalsefalse2falsefalsetruefalse{dei_DocumentInformationDocumentAxis} : SummaryS000028356-2 Member {dei_LegalEntityAxis} : S000028356 Member {rr_ProspectusShareClassAxis} : C000086651 Member 3/1/2011 - 3/1/2011 eol_0001135428-11-000118_STD_1_20110301_0_396770x-9994272_396840x-9994244_429423x-9994296http://www.sec.gov/CIK0000878719duration2011-03-01T00:00:002011-03-01T00:00:00falsefalseSands Capital Global Growth Fund (Second Prospectus Summary)dei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000878719_SummaryS000028356-2Memberdei_DocumentInformationDocumentAxisexplicitMemberfalsefalseSands Capital Global Growth Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000878719_S000028356Memberdei_LegalEntityAxisexplicitMemberfalsefalseInvestor Class Sharesrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000878719_C000086651Memberrr_ProspectusShareClassAxisexplicitMemberOthernaNo definition available.No authoritative reference available.falsefalseSands Capital Global Growth Fund (Second Prospectus Summary) | Sands Capital Global Growth Fund | Investor Class Shares29true0rr_RiskReturnAbstractrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringNo definition available.falsefalseRisk/Return:30false0rr_FeeWaiverOrReimbursementOverAssetsDateOfTerminationrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse002012-02-29falsefalsefalsefalsefalseOtherus-types:dateStringItemTypenormalizedstringThis element represents the date of expected termination of any expense reimbursement or fee waiver arrangements that reduce any Fund operating expenses (SEC Form N-1A 2006-09-14 A.3.table.1.11 Total Annual Fund Operating Expenses A.3.instructions.3.e).Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 3 -Subparagraph e -Subsection instructions falsefalseFee Waiver or Reimbursement over Assets, Date of Termination31false0natruenanaNo definition available.falsetruefalsefalsefalsefalsefalsefalsefalsefalsehttp://www.acadian-asset.com/role/riskreturndetaildata_s000028356member21falsefalsefalse00falsefalsefalsefalsefalse4falsefalseUSDtruefalse{dei_LegalEntityAxis} : S000028356 Member {rr_ProspectusShareClassAxis} : C000086651 Member 3/1/2011 - 3/1/2011 USD ($) $eol_0001135428-11-000118_STD_1_20110301_0_396770x-9994272_429423x-9994296http://www.sec.gov/CIK0000878719duration2011-03-01T00:00:002011-03-01T00:00:00falsefalseSands Capital Global Growth Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000878719_S000028356Memberdei_LegalEntityAxisexplicitMemberfalsefalseInvestor Class Sharesrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000878719_C000086651Memberrr_ProspectusShareClassAxisexplicitMemberpureStandardhttp://www.xbrl.org/2003/instancepure0iso4217_USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$OthernaNo definition available.No authoritative reference available.falsefalseSands Capital Global Growth Fund | Investor Class Shares32true0rr_RiskReturnAbstractrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringNo definition available.falsefalseRisk/Return:33false0rr_RedemptionFeeOverRedemptionrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue-0.0200-0.0200falsefalsefalsefalsefalseOtherrr:NonPositivePure4Typepure"Redemption Fee" (as a percentage of amount redeemed, if applicable) If the Fund is an Exchange-Traded Fund and issues or redeems shares in creation units of not less than 25,000 shares each, exclude any fees charged for the purchase and redemption of the Fund's creation units.

If there were expense reimbursement or fee waiver arrangements that reduced any Fund operating expenses and will continue to reduce them for no less than one year from the effective date of the Fund's registration statement, a Fund may add two captions to the table one caption showing the amount of the expense reimbursement or fee waiver, and a second caption showing the Fund's net expenses after subtracting the fee reimbursement or expense waiver from the total fund operating expenses. The Fund should place these additional captions directly below the "Total Annual Fund Operating Expenses" caption of the table and should use appropriate descriptive captions, such as "Fee Waiver [and/or Expense Reimbursement]" and "Total Annual Fund Operating Expenses After Fee Waiver [and/or Expense Reimbursement]," respectively.
