If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

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: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]22false 3rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of real estate and real estate-related issuers, and in derivatives and other instruments that have economic characteristics similar to such securities. The Fund invests primarily in real estate investment trusts (REITs) and equity securities. The principal types of equity securities in which the Fund invests are common and preferred stocks and convertible securities.<br /><br />The Fund considers an issuer to be a real estate or real estate-related issuer if at least 50% of its assets, gross income or net profits are attributable to ownership, construction, management or sale of residential, commercial or industrial real estate. These issuers include (i) REITs or other real estate operating issuers that (a) own property, (b) make or invest in short-term construction and development mortgage loans, or (c) invest in long-term mortgages or mortgage pools, and (ii) issuers whose products and services are related to the real estate industry, such as manufacturers and distributors of building supplies and financial institutions that issue or service mortgages.<br /><br />The Fund may also invest in debt securities, including corporate debt obligations and commercial mortgage-backed securities. The Fund may invest up to 10% of its net assets in non-investment grade debt securities (commonly known as &#8220;junk bonds&#8221;) of real estate and real estate-related issuers.<br /><br />The Fund may invest in securities of issuers of all capitalization sizes. Real estate companies tend to have smaller asset bases compared with other market sectors, therefore, the Fund may hold a significant amount of securities of small- and mid-capitalization issuers.<br /><br />The Fund may invest up to 25% of its net assets in foreign securities. In regard to foreign security holdings, up to 10% of the Fund&#8217;s net assets may be in securities of issuers located in emerging markets countries, i.e., those that are in the initial stages of their industrial cycles.<br /><br />The Fund may engage in short sales of securities. The Fund may engage in short sales with respect to securities it owns or securities it does not own. Generally, the Fund will sell a security short to (1) take advantage of an expected decline in the security price in anticipation of purchasing the same security at a later date at a lower price, or (2) to protect a profit in a security that it owns. The Fund will not sell a security short if, as a result of such short sale, the aggregate market value of all securities sold short exceeds 15% of the Fund&#8217;s net assets.<br /><br />The Fund can invest in derivative instruments including forward foreign currency contracts.<br /><br />The Fund can use forward foreign currency contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.<br /><br />When constructing the portfolio, the portfolio managers use a fundamentals-driven investment process, including an evaluation of factors such as property market cycle analysis, property evaluation and management and structure review to identify securities with characteristics including (i) quality underlying properties, (ii) solid management teams with the ability to effectively manage capital structure decisions and execute their stated strategic plan, and (iii) attractive valuations relative to peer investment alternatives. <br /><br />The portfolio managers and investment team focus on equity REITs and real estate operating issuers. Each qualified security in the investment universe is analyzed using fundamental real estate analysis and valuation review to identify securities that appear to have relatively favorable long-term prospects and attractive values. Some of the fundamental real estate factors that are considered include: forecasted occupancy and rental rates of the various property markets in which a firm may operate, property locations, physical attributes, management depth and skill, insider ownership, overall debt levels, percentage of variable rate financing and fixed charge coverage ratios. The issuers that are believed to have the most attractive fundamental real estate attributes are then evaluated on the basis of relative value. Some of the valuation factors that are considered include: cash flow consistency and growth, dividend yield, dividend coverage and growth, and cash flow and assets to price multiples.<br /><br />The portfolio managers seek to construct a portfolio with risk characteristics similar to the FTSE NAREIT All Equity REITs Index (the benchmark index). The Fund uses the benchmark index as a guide in structuring the portfolio, but the Fund is not an index fund.<br /><br />The portfolio managers seek to limit risk through various controls, such as diversifying the portfolio property types and geographic areas as well as by considering the relative liquidity of each security and limiting the size of any one holding.<br /><br />The portfolio managers will consider selling a security if they conclude (1) its relative valuation has fallen below desired levels, (2) its risk/return profile has changed significantly, (3) its fundamentals have changed, or (4) a more attractive investment opportunity is identified.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:<br /><br />Concentration Risk. To the extent the Fund invests a greater amount in any one sector or industry, the Fund&#8217;s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to the Fund if conditions adversely affect that sector or industry.<br /><br />Convertible Securities Risk. The Fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.<br /><br />Credit Risk. The issuer of instruments in which the Fund invests may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer&#8217;s credit rating.<br /><br />Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index, commodity or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the Adviser elects not to do so due to availability, cost, market conditions or other factors.<br /><br />Developing/Emerging Markets Securities Risk. The prices of securities issued by foreign companies and governments located in developing/emerging markets countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries.<br /><br />Foreign Securities Risk. The Fund&#8217;s foreign investments may be affected by changes in a foreign country&#8217;s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.<br /><br />High Yield Bond (Junk Bond) Risk. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time.<br /><br />Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration.<br /><br />Management Risk. The investment techniques and risk analysis used by the Fund&#8217;s portfolio managers may not produce the desired results.<br /><br />Market Risk. The prices of and the income generated by the Fund&#8217;s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.<br /><br />Mortgage- and Asset-Backed Securities Risk. The Fund may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower&#8217;s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, the Fund may reinvest these early payments at lower interest rates, thereby reducing the Fund&#8217;s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of mortgage-backed securities and could result in losses to the Fund. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. Subprime mortgages refer to loans made to borrowers with weakened credit histories or with lower capacity to make timely payments on their mortgages.<br /><br />Preferred Securities Risk. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments.<br /><br />REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to the Fund&#8217;s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, the Fund may own real estate directly, which involves the following additional risks: environmental liabilities, difficulty in valuing and selling the real estate, and economic or regulatory changes.<br /><br />Short Sales Risk. Short sales may cause the Fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, the Fund&#8217;s exposure is unlimited.<br /><br />Small- and Mid-Capitalization Risks. Stocks of small- and mid-sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small- and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.
