DoubleLine Floating Rate Fund

“Acquired Fund Fees and Expenses” are expenses indirectly incurred by the Fund as a result of its investments in one or more underlying funds, including exchange-traded funds and money market funds. Because these costs are indirect, the Total Annual Fund Operating Expenses in this fee table will not correlate to the expense ratio in the Fund’s financial statements, since financial statements only include direct costs of the Fund and not the indirect costs of investing in the underlying funds.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (taking into account the Fund’s expense limitation for the first year). Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in floating rate loans and other floating rate investments.

Floating rate loans are typically debt obligations with interest rates that adjust or “float” periodically, often on a daily, monthly, quarterly, or semiannual basis by reference to a base lending rate (such as LIBOR) plus a premium. Certain floating rate loans are secured by specific collateral of the borrower and are senior to most other securities of the borrower (e.g., common stock and other debt instruments) in the event of bankruptcy (“Senior Loans”). Other floating rate loans may be unsecured obligations of the borrower. A floating rate loan may be structured and administered by a financial institution that acts as the agent of the lenders participating in the floating rate loan. Such floating rate loans may be acquired through the agent or from the borrower, as an assignment from another lender who holds a direct interest in the floating rate loan, or as a participation interest in another lender’s portion of the floating rate loan.

Other “floating rate investments” include, without limitation, floating rate debt securities; inflation-indexed securities; certain mortgage- and asset-backed securities, collateralized loan obligations, collateralized debt obligations, and collateralized mortgage obligations backed by or structured as floating rate investments and having, in the judgment of the Adviser, characteristics similar to those of other floating rate investments; adjustable rate mortgages; floaters; inverse floaters; money market securities of all types; repurchase agreements; and shares of money market and short-term bond funds.

The Fund normally will invest at least 80% of its net assets (plus the amount of borrowings for investment purposes) in floating rate loans and other floating rate investments. For purposes of this policy, any security or instrument will be considered a floating rate investment if it has a maturity of six months or less even if it pays a rate of interest rate that does not reset or adjust prior to maturity. The Fund’s investments in derivatives and other synthetic instruments that provide exposure comparable, in the judgment of the Adviser, to floating rate investments will be counted toward satisfaction of this 80% policy as well.

The Fund may invest in securities or instruments of any credit quality. The Fund expects that many or all of the Fund’s investments will be rated below investment grade or unrated but of comparable credit quality. Floating rate and other investments rated below investment grade, or unrated securities that are determined by the Adviser to be of comparable quality, are high yield, high risk securities, commonly known as junk bonds. Such investments entail high risk and have speculative characteristics. The Fund may invest in securities of stressed, distressed, and defaulted issuers (including issuers involved in bankruptcy proceedings, reorganizations, financial restructurings, or otherwise experiencing financial hardship).

Subject to the Fund’s policy to invest at least 80% of its net assets in floating rate loans and other floating rate investments, the Fund may invest any portion of its assets in bonds, debentures, notes and other debt instruments, preferred securities, money market securities, investment-grade debt securities, repurchase agreements, and any security or instrument bearing a floating or adjustable rate of interest, including by investing in other investment companies or pools, exchange-traded funds (“ETFs”), and domestic or foreign private investment vehicles.

The Fund may invest in obligations of corporate and governmental issuers of any maturity. The Fund may invest in foreign investments, including obligations of issuers in emerging markets, without limit.

The Fund’s investments in loans may include loans issued in an offering that has been oversubscribed. The Fund may be able to sell such investments at a gain shortly after those investments are made. If the Fund seeks to take advantage of such opportunities, it may lead to higher levels of portfolio turnover, increased transaction costs and greater amounts of taxable distributions to shareholders. There can be no assurance that the Adviser will be able to identify such opportunities successfully or sell any investments at a gain.

The Fund may enter into derivatives transactions and other instruments of any kind for duration management purposes, hedging purposes or otherwise to gain, or reduce, long or short exposure to one or more asset classes or issuers. The Fund also may use derivatives transactions with the purpose or effect of creating investment leverage.

The Fund’s portfolio managers may consider a wide variety of factors in purchasing and selling investments for the Fund, including, without limitation, fundamental analysis of the issuer, the credit quality of the issuer and any collateral securing the investment, the issuer’s management, capital structure, leverage, and operational performance, and the business outlook for the industry of the issuer. The Fund also may consider available credit ratings. Although the Fund’s portfolio managers may consider credit ratings in making investment decisions, they typically perform their own investment analysis and generally do not rely upon the independent credit rating agencies in making investment decisions.

Portfolio securities may be sold at any time. For example, the Fund’s portfolio managers may sell a Fund investment in order to take advantage of what they consider to be a better investment opportunity, when they believe the investment no longer represents a relatively attractive investment opportunity, when they perceive deterioration in the credit fundamentals of the issuer, or when the individual investment has reached the portfolio managers’ sell target.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Since the Fund will hold securities with fluctuating market prices, the value of the Fund’s shares will vary as its portfolio securities increase or decrease in value. Therefore, the value of your investment in the Fund could go down as well as up. You can lose money by investing in the Fund.

The principal risks affecting the Fund that can cause a decline in value are:

affiliated fund risk: the risk that the Adviser may be subject to a potential conflict of interest in determining whether to invest in an underlying fund managed by the Adviser or in a fund managed by an unaffiliated manager, and may have an economic or other incentive to select the fund managed by it over another fund. Similarly, the Adviser may be subject to a similar potential conflict of interest in determining whether other funds managed by the Adviser should invest in (or cease investing in) the Fund.

asset-backed securities investment risk: the risk that borrowers may default on the obligations that underlie the asset-backed security and that, during periods of falling interest rates, asset-backed securities may be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate, and the risk that the impairment of the value of the collateral underlying a security in which the Fund invests (due, for example, to non-payment of loans) will result in a reduction in the value of the security.

confidential information access risk: the risk that the intentional or unintentional receipt of material, non-public information (“Confidential Information”) by the Adviser could limit the Fund’s ability to sell certain investments held by the Fund or pursue certain investment opportunities on behalf of the Fund, potentially for a substantial period of time. Also, certain issuers of floating rate loans or other investments may not have any publicly traded securities (“Private Issuers”) and may offer private information pursuant to confidentiality agreements or similar arrangements. The Adviser may access such private information, while recognizing that the receipt of that information could potentially limit the Fund’s ability to trade in certain securities if the Private Issuer later issues publicly traded securities. In addition, in circumstances when the Adviser declines to receive Confidential Information from issuers of floating rate loans or other investments, the Fund may be disadvantaged in comparison to other investors, including with respect to evaluating the issuer and the price the Fund would pay or receive when it buys or sells those investments. In managing the Fund, the Adviser may seek to avoid the receipt of Confidential Information about the issuers of floating rate loans or other investments being considered for acquisition by the Fund or held in the Fund’s portfolio if the receipt of the Confidential Information would restrict one or more of the Adviser’s clients, including, potentially, the Fund, from trading in securities they hold or in which they may invest.

counterparty risk: the risk that the Fund will be subject to credit risk with respect to the counterparties to the derivative contracts and other instruments entered into directly by the Fund or held by special purpose or structured vehicles in which the Fund invests.

debt securities risks:

credit risk: the risk that an issuer or counterparty will default in the payment of principal and/or interest on a security and, as a result, the Fund’s income might be reduced, the value of the Fund’s investment might fall, and/or the Fund could lose the entire amount of its investment. Changes in the financial condition of an issuer or counterparty, changes in specific economic, social or political conditions that affect a particular type of security or issuer, and changes in economic, social or political conditions generally can increase the risk of default by an issuer or counterparty, which can affect a security’s or instrument’s credit quality or value and an issuer’s or counterparty’s ability to pay interest and principal when due. Lower-quality debt securities (those of less than investment-grade quality), including floating rate loans, tend to be particularly sensitive to these changes. The value of securities also may decline for a number of other reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services, as well as the historical and prospective earnings of the issuer and the value of its assets.

extension risk: the risk that if interest rates rise, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates rise, which could cause their values to fall sharply. Interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments.

interest rate risk: the risk that debt securities will decline in value because of increases in interest rates. The value of a security with a longer duration will be more sensitive to changes in interest rates than a similar security with a shorter duration.

defaulted securities risk: the risk of the uncertainty of repayment of defaulted securities and obligations of distressed issuers.

derivatives risk: the risk that an investment in derivatives will not perform as anticipated by the Adviser, cannot be closed out at a favorable time or price, or will increase the Fund’s volatility; that derivatives may create investment leverage; that, when a derivative is used as a substitute for or alternative to a direct cash investment, the transaction may not provide a return that corresponds precisely with that of the cash investment; or that, when used for hedging purposes, derivatives will not provide the anticipated protection, causing the Fund to lose money on both the derivatives transaction and the exposure the Fund sought to hedge.

emerging market country risk: the risk that investing in emerging markets will be subject to greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers, an emerging market country’s dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, and less developed legal systems than in many more developed countries.

financial services risk: the risk that an investment in issuers in the financial services sector may be adversely affected by, among other things: (i) changes in the regulatory framework or economic conditions that may negatively affect financial service businesses; (ii) exposure of a financial institution to non diversified or concentrated loan portfolios; (iii) exposure to financial leverage and/or investments or agreements which, under certain circumstances, may lead to losses, for example sub-prime loans; and (iv) the risk that a market shock or other unexpected market, economic, political, regulatory, or other event might lead to a sudden decline in the values of most or all companies in the financial services sector.

foreign currency risk: the risk that fluctuations in exchange rates may adversely affect the value of the Fund’s investments denominated in foreign currencies.

foreign investing risk: the risk that the Fund’s investments will be affected by political, regulatory, and economic risks not present in domestic investments. In addition, when the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate or restrict foreign exchange transactions. In addition, to the extent that investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund.

inflation-indexed bond risk: the risk that such bonds will change in value in response to actual or anticipated changes in inflation rates, in a manner unanticipated by the Fund’s portfolio management team or investors generally. Inflation-indexed bonds are subject to debt securities risks.

investment company and exchange traded fund risk: the risk that an investment company, including any ETF, in which the Fund invests will not achieve its investment objective or execute its investment strategies effectively or that large purchase or redemption activity by shareholders of such an investment company might negatively affect the value of the investment company’s shares. The Fund must pay its pro rata portion of an investment company’s fees and expenses.

junk bond risk: the risk that these bonds have a higher degree of default risk and may be less liquid and subject to greater price volatility than investment grade bonds.

leveraging risk: the risk that certain investments by the Fund involving leverage may have the effect of increasing the volatility of the Fund’s portfolio, and the risk of loss in excess of invested capital.

limited operating history risk: the risk that a newly formed fund has a limited operating history to evaluate and may not attract sufficient assets to achieve or maximize investment and operational efficiencies.

liquidity risk: the risk that low trading volume, extreme market volatility, unusually high and unanticipated levels of redemptions, lack of a market maker, or contractual or legal restrictions may limit or prevent the Fund from selling securities or closing derivative positions at desirable times or prices. The market for illiquid securities is more volatile than the market for liquid securities and it may be more difficult to value accurately the Fund’s illiquid investments.

loan risk: includes the risk that (i) if the Fund holds a loan through another financial institution, or relies on a financial institution to administer the loan, its receipt of principal and interest on the loan may be subject to the credit risk of that financial institution; (ii) it is possible that any collateral securing a loan may be insufficient or unavailable to the Fund, because, for example, the value of the collateral securing a loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate, and that the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws; (iii) investments in highly leveraged loans or loans of stressed, distressed, or defaulted issuers may be subject to significant credit and liquidity risk; (iv) a bankruptcy or other court proceeding could delay or limit the ability of the Fund to collect the principal and interest payments on that borrower’s loans or adversely affect the Fund’s rights in collateral relating to a loan; (v) there may be limited public information available regarding the loan; (vi) the use of a particular interest rate benchmark, such as LIBOR, may limit the Fund’s ability to achieve a net return to shareholders that consistently approximates the average published Prime Rate of U.S. banks; (vii) the prices of certain floating rate loans that include a feature that prevents their interest rates from adjusting below a specified minimum level may be more sensitive to changes in interest rates should short-term interest rates rise but remain below the applicable minimum level; (viii) if a borrower fails to comply with various restrictive covenants that are typically in loan agreements, the borrower may default in payment of the loan; (ix) the Fund’s investments in Senior Loans may be subject to increased liquidity and valuation risks, risks associated with collateral impairment or access, and risks associated with investing in unsecured loans; (x) opportunities to invest in loans or certain types of loans, such as Senior Loans, may be limited, (xi) transactions in loans may settle on a delayed basis, and the Fund may not receive the proceeds from the sale of a loan for a substantial period of time after the sale; and (xii) loans may be difficult to value and may be illiquid, which may adversely affect an investment in the Fund. In addition, equity securities, including those acquired by the Fund in connection with a loan (e.g., as part of an instrument combining a loan and equity securities), are subject to market risks and the risks of changes to the financial condition of the issuer, and fluctuations in value.

market risk: the risk that the overall market will perform poorly or that the returns from the securities in which the Fund invests will underperform returns from the general securities markets or other types of investments.

mortgage-backed securities risks: the risk that borrowers may default on their mortgage obligations or the guarantees underlying the mortgage-backed securities will default or otherwise fail and that, during periods of falling interest rates, mortgage-backed securities will be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of a mortgage-backed security may extend, which may lock in a below-market interest rate, increase the security’s duration, and reduce the value of the security. Enforcing rights against the underlying assets or collateral may be difficult, or the underlying assets or collateral may be insufficient if the issuer defaults. The values of certain types of mortgage-backed securities, such as inverse floaters and interest-only and principal-only securities, may be extremely sensitive to changes in interest rates and prepayment rates.

portfolio management risk: the risk that an investment strategy may fail to produce the intended results or that the securities held by the Fund will underperform other comparable funds because of the portfolio managers’ choice of investments.

portfolio turnover risk: the risk that frequent purchases and sales of portfolio securities may result in higher Fund expenses and may result in larger distributions of taxable capital gains to investors as compared to a fund that trades less frequently.

preferred securities risk: the risk that: (i) certain preferred stocks contain provisions that allow an issuer under certain conditions to skip or defer distributions; (ii) preferred stocks may be subject to redemption, including at the issuer’s call, and, in the event of redemption, the Fund may not be able to reinvest the proceeds at comparable rates of return; (iii) preferred stocks are generally subordinated to bonds and other debt securities in an issuer’s capital structure in terms of priority for corporate income and liquidation payments; and (iv) preferred stocks may trade less frequently and in a more limited volume and may be subject to more abrupt or erratic price movements than many other securities.

prepayment risk: the risk that the issuer of a debt security, including floating rate loans and mortgage-related securities, repays all or a portion of the principal prior to the security’s maturity. In times of declining interest rates, this may result in a portion of the Fund’s higher yielding securities being pre-paid and the Fund being unable to re-invest the proceeds in an investment with as great a yield. Prepayments can therefore result in lower yields to shareholders of the Fund. Interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments.

price volatility risk: the risk that the value of the Fund’s investment portfolio will change, potentially frequently and in large amounts, as the prices of its investments go up or down.

securities or sector selection risk: the risk that the securities held by the Fund will underperform securities held in other funds investing in similar asset classes or comparable benchmarks because of the portfolio managers’ choice of securities or sectors for investment.

U.S. Government securities risk: the risk that debt securities issued or guaranteed by certain U.S. Government agencies, instrumentalities, and sponsored enterprises are not supported by the full faith and credit of the U.S. Government, and so involve credit risk greater than investments in other types of U.S. Government securities.
