Net operating expenses of the Fund, based on the average daily net assets, are limited to 1.00% for Class A shares and 0.75% for Class I shares. Acquired Fund Fees and Expenses are excluded from this calculation. This arrangement does not include interest, taxes, brokerage commissions, and extraordinary expenses. The Fund has agreed to repay the Adviser for expenses reimbursed to the Fund provided that repayment does not cause the Fund's total annual operating expenses to exceed the Expense Limitation. Any such repayment must be made within three years after the year in which the Adviser incurred the expense.2Total Annual Fund Operating Expenses shown in the table above may not correspond to the ratio of net expenses to the average net assets in the "Financial Highlights" section of this Prospectus to the extent that Acquired Fund Fees and Expenses are included in the table above.24Annual Fund Operating Expenses - Artio Global High Income Fund

falsefalse17false0rr_StrategyNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<p>The Fund normally invests in lower quality, high income producing investments. The majority of the strategy is directed toward below investment grade securities denominated in U.S. dollars. Debt securities rated below investment grade are commonly referred to as “junk bonds” and are considered speculative. However, the Fund may also invest in non-U.S. dollar securities including those in emerging markets. The Adviser uses a top-down/bottom-up process which brings together insights related to issue, industry, asset class, macroeconomics, maturity and sector. The Adviser seeks to identify stable to improving investment opportunities through an approach which examines the industry in which an issuer operates as well as how that industry is evolving. Further analysis is directed at determining how the issuer is positioned, its strengths and weaknesses, and other factors.</p><p>• Under normal circumstances, the Fund will invest at least 80% of its net assets (including high income related futures, options, swaps and other instruments as well as borrowings for investment purposes) in a diversified portfolio of high income producing instruments of issuers located throughout the world, including in emerging market countries. The Fund will provide shareholders with at least 60 days notice prior to any changes in this policy.</p><p>• Invests in fixed income securities, debt instruments convertible into common stock, preferred stock and swaps.</p><p>• Invests in securities issued by corporations, banks, governments, government entities and supranational organizations.</p><p>• Normally invests at least 60% of its net assets in U.S. dollar denominated securities.</p><p>• Ordinarily invests in no fewer than three different countries outside the U.S.</p><p>• Invests in securities the Adviser believes exhibit stable to improving credit terms based on industry characteristics and trends, company positioning and management strategy.</p><p>• Invests in bank loans.</p><p>• May invest in delayed funding loans and revolving credit facilities.</p><p>• Invests in derivatives for hedging and non-hedging purposes. Derivatives are financial instruments the value of which is derived from another security, a commodity (such as gold or oil), an index or a currency (a measure of value or rates, such as the S&P 500 Index or the prime lending rate). The Fund typically uses derivatives as a substitute for taking a position in an underlying asset and/or as part of a strategy to reduce risk, such as interest rate risk, currency risk, and price risk. The Fund expects that derivative instruments will include, but are not limited to, futures contracts, forward contracts, non-deliverable forwards, options, options on futures, swaps, interest rate warrants, and structured notes. A forward contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. Forward contracts are the primary means of hedging currency exposure. A futures contract commits the parties to a transaction at a time in the future at a price determined when the transaction is initiated and generally trade through regulated exchanges and are “marked to market” daily both of which reduce liquidity risk. A swap is an agreement between two parties to exchange certain financial instruments or components of financial instruments such as streams of interest rate payments, principal denominated in two different currencies, or virtually any payment stream as agreed to by the parties. A credit default swap is a credit derivative contract between two counterparties. The buyer makes periodic payments to the seller, and in return receives protection if an underlying financial instrument defaults.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

falsefalse19false0rr_RiskNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<p>Global securities markets and the world economy have been subject to significant volatility recently which has increased the risks associated with an investment in the Fund. Investments in the Fund carry a certain amount of risk and the Fund cannot guarantee that it will achieve its investment objective. You may lose money by investing in the Fund. Below are the principal risks of investing in the Fund:</p><p><b>• Maturity Risk:</b> The Fund’s investments in fixed income securities may lose value because of declines in the bond market; longer-term securities are generally more volatile. Duration takes into account the pattern of a security’s cash flow over time, including the way cash flow may be affected by prepayments and interest rate changes.</p><p><b>• Below Investment Grade Securities Risk:</b> The Fund’s investments in lower quality debt securities are generally more speculative, less liquid and subject to higher incidence of default than investment grade securities.</p><p><b>• Interest Rate Risk:</b> The Fund’s fixed income investments are subject to interest rate risk which generally causes the value of a fixed income portfolio to decrease when interest rates rise resulting in a decrease in the Fund’s net assets. Interest rate fluctuations tend to have a greater impact on fixed income-securities with longer durations.</p><p><b>• Credit Risk:</b> Fixed income securities are subject to credit risk, which is the risk that an issuer of a bond will be unable to repay interest and principal in a timely manner. In the event of an unanticipated default, the Fund would experience a reduction in its income and could expect a decline in the market value of the securities so affected.</p><p><b>• Foreign Investment Risk:</b> The Fund will invest in foreign securities which may lose value because of fluctuations in currency exchange rates and market liquidity, price volatility, uncertain political and legal conditions, lack of reliable financial information and other factors. Foreign securities of certain countries are subject to political instability, which may result in potential revolts and the confiscation of assets by governments. As a result, the Fund’s returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country or region. In the event of nationalization, expropriation or other confiscation or capital controls, the Fund could lose its entire investment in foreign securities. Adverse conditions in a certain region can adversely affect securities of other countries whose economies appear to be unrelated. To the extent that the Fund invests a significant portion of its assets in a specific geographic region, the Fund will generally have more exposure to regional economic risks associated with foreign investments.</p><p><b>• Emerging Market Risk:</b> The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries. Emerging markets are generally smaller, less developed, less liquid, and more volatile than developed markets, and are subject to greater social, political and economic uncertainties, higher levels of inflation and currency devaluation and settlement and operational risks, including risks related to foreign securities custody. Investments in countries of Central and Eastern Europe and former states of the Soviet Union, including Russia, are subject to greater risk of expropriation of private industry and a partial or total loss of an investment in such foreign securities.</p><p><b>• Foreign Currency Transaction Risk:</b> As foreign securities are usually denominated in foreign currencies, the Fund may employ strategies intended to protect the Fund’s portfolio from adverse currency fluctuations. The Fund may also employ strategies intended to increase exposure to certain currencies. Such currency transactions involve additional risks, and the Fund’s strategies, if unsuccessful, may decrease the value of the Fund.</p><p><b>• Regulatory Risk:</b> Foreign companies may not be registered with the SEC and are generally not subject to the regulatory controls imposed on United States issuers and, as a consequence, there is generally less publically available information about foreign securities than is available about domestic securities. Foreign companies may not be subject to uniform accounting, auditing and financial reporting standards, corporate governance practices and requirements comparable to those applicable to domestic companies. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce dividend income payable to the Fund’s shareholders.</p><p><b>• Liquidity Risk:</b> Particular investments may be difficult to purchase or sell such as fixed-income securities which have not received any credit ratings, below investment grade securities or securities that are not widely held. The Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions, which may reduce the returns of the Fund because it may be unable to sell the illiquid securities at an advantageous time or price. From time to time, as a result of significant adverse market conditions, some investments the Fund may purchase may become illiquid which may cause the Fund difficulty in meeting redemptions.</p><p><b>• Derivatives Risk:</b> Derivatives can be highly volatile and involve risks in addition to the risks of the underlying investment, index or rate. Derivatives involve special risks including correlation, counterparty, liquidity, operational, accounting and tax risks. Investing in derivatives also requires a specific skill set and may result in losses. Derivatives may be illiquid, difficult to price and leveraged so that small changes may produce disproportionate losses. Gains or losses from derivatives can be substantially greater than the derivatives’ original cost. Derivatives can be complex instruments and can involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class the derivative is intended to provide exposure to, the derivative may not have the anticipated effect. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments.</p><p>The Fund may substantially increase its use of derivatives in response to unusual market conditions that limit the Fund’s investment opportunities.</p><p><b>• Leveraging Risk:</b> Certain transactions may give rise to a form of leverage. Such transactions may include, among others, loans of securities, and the use of when-issued, delayed delivery or forward commitment transactions. The use of derivatives may also cause leveraging risk.</p><p><b>• Bank Loan Risk:</b> There are a number of risks associated with an investment in bank loans including credit risk, interest rate risk, liquidity risk, and prepayment risk. There is also the possibility that the collateral securing a loan, if any, may be difficult to liquidate or be insufficient to cover the amount owed under the loan. These risks could cause the Fund to lose income or principal on a particular investment, which in turn could affect the Fund’s returns.</p><p><b>• Delayed Funding Loans and Revolving Credit Facilities Risk:</b> There are a number of risks associated with an investment in delayed funding loans and revolving credit facilities including credit, interest rate and liquidity risk and the risks of being a lender. There may be circumstances under which the borrowing issuer’s credit risk may be deteriorating and yet the Fund may be obligated to make loans to the borrowing issuer as the borrowing issuer’s credit continues to deteriorate, including at a time when the borrowing issuer’s financial condition makes it unlikely that such amounts will be repaid. Delayed funding loans and revolving credit facilities may be subject to restrictions on transfer, and only limited opportunities may exist to resell such instruments.</p><p><b>• Custody/Sub-Custody Risk:</b> The Fund may invest in markets where custodial and/or settlement systems are not fully developed. There may be very limited regulatory oversight of certain foreign banks or securities depositories that hold foreign securities and foreign currency. The laws of certain countries may limit the ability to recover such assets if a foreign bank or depository or their agents goes bankrupt and the assets of the Fund may be exposed to risk in circumstances where the custodian/sub-custodian or Adviser will have no liability. In addition, the inability of the Fund to make its intended securities purchases due to settlement issues with the custodian/sub-custodian could cause the Fund to miss attractive investment opportunities.</p><p><b>• Redemption Risk:</b> The Fund may need to sell its portfolio holdings in order to meet shareholder redemption requests. In selling its holdings to meet redemption requests, the Fund could experience a loss if the redemption requests are unusually large or frequent, occur in times of overall market turmoil, or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.</p><p>An investment in the Fund is not a bank deposit or obligation of any bank and is not endorsed or guaranteed by any bank and is not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other governmental agency.</p><p>You could lose money investing in the Fund.</p><p>Further information about the Fund’s strategies and risks is provided in the section, <i>Fund Strategies and Risks.</i></p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The table demonstrates these risks by showing how the Fund’s annual returns of Class A shares compare to the performance of a broad-based market index over various periods of time. The Fund’s average annual return figures for the one-year, five-year and ten-year/since inception periods are net of applicable fee waivers and/or certain expense offset arrangements. The Fund’s average annual return figures without fee waivers and expense offset arrangements would have been lower. You cannot invest directly in an index. Unlike a mutual fund, an index does not incur expenses. If expenses were deducted, actual returns of the index would be lower. Returns (before and after taxes) are based on past results and are not an indication of future performance. Returns for Class I shares will differ to the extent that Class I has lower expenses.

Actual after-tax returns depend on the investor’s tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares, and after-tax returns for Class I shares will differ. Past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringIf the Fund has annual returns for at least one calendar year, provide a table showing the Fund's (A) average annual total return; (B) average annual total return (after taxes on distributions); and (C) average annual total return (after taxes on distributions and redemption). A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also shouldshow the returns of an appropriate broadbased securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: 1
