Lazard U.S. Realty Income Portfolio

RISK/RETURN

Investment Objectives

The Portfolio’s primary investment objective is current income, with long-term capital appreciation as a secondary objective.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Portfolio, a series of The Lazard Funds, Inc. (the “Fund”).

Shareholder Transaction Fees (fees paid directly from your investment)

Shareholder Fees Lazard U.S. Realty Income Portfolio	Institutional Shares	Open Shares
Maximum Redemption Fee (as a % of amount redeemed, on shares owned for 30 days or less)	1.00%	1.00%

Annual Portfolio Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses Lazard U.S. Realty Income Portfolio		Institutional Shares	Open Shares
Management Fees		0.75%	0.75%
Distribution and Service (12b-1) Fees		none	0.25%
Other Expenses*		1.01%	1.06%
Acquired Fund Fees and Expenses	[1]	0.01%	0.01%
Total Annual Portfolio Operating Expenses	[1]	1.77%	2.07%
Fee Waiver and Expense Reimbursement	[2]	0.61%	0.61%
Total Annual Portfolio Operating Expenses After Fee Waiver and Expense Reimbursement	[2]	1.16%	1.46%

Example

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

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 periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same, giving effect to the fee waiver. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example Lazard U.S. Realty Income Portfolio (USD $)	1 Year	3 Years
Institutional Shares	118	368
Open Shares	149	462

Portfolio Turnover

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 and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the portfolio turnover rate of the Predecessor Realty Income Fund (defined below) was 77.4% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Portfolio invests at least 80% of its assets in dividend-paying common and preferred stocks, convertible securities and fixed income securities of U.S. Realty Companies (defined below), as well as certain synthetic instruments related to U.S. Realty Companies. Such synthetic instruments are investments that have economic characteristics similar to the Portfolio’s direct investments in U.S. Realty Companies and may include warrants, rights, options and shares of exchange-traded funds (“ETFs”).

The Investment Manager focuses on investments having the potential to deliver regular income and to offer the opportunity for long-term growth and capital appreciation. The Investment Manager conducts proprietary quantitative, qualitative and on-site real estate analysis to select the Portfolio’s investments, which may include, as appropriate, research at the macroeconomic, sector, company and property level. The Investment Manager’s individual company research may consider a number of quantitative measures, including earnings growth potential, price to earnings or free cash flow multiples, price to net asset value ratios, dividend yield and potential for growth, return on equity and return on assets, as well as qualitative factors such as overall business and growth strategy and quality of management.

“Realty Companies” are real estate-related companies of any size including, but not limited to, real estate investment trusts (“REITs”), real estate operating or service companies and companies in the homebuilding, lodging and hotel industries, as well as companies engaged in the healthcare, gaming, retailing, restaurant, natural resources and utility industries, and other companies whose investments, balance sheets or income statements are real-estate intensive (i.e., the company’s actual or anticipated revenues, profits, assets, services or products are related to real estate including, but not limited to, the ownership, renting, leasing, construction, management, development or financing of commercial, industrial or residential real estate).

The Portfolio’s investments in preferred stock and convertible and fixed income securities may include securities which, at the time of purchase, are rated below “investment grade” by a nationally recognized statistical rating organization (“NRSRO”), or the unrated equivalent as determined by the Investment Manager (“junk bonds”).

The Portfolio may invest in issuers of any market capitalization and securities of any maturity, and the Portfolio’s investments also may include securities purchased in initial public offerings (“IPOs”).

The Portfolio also may invest up to 25% of its net assets in companies organized as master limited partnerships and their affiliates.

The Portfolio also may invest up to 20% of its assets in other securities and instruments of companies or entities (which need not be U.S. Realty Companies), including, but not limited to, securities of non-U.S. companies and other investment companies.

The Portfolio may, but is not required to, write put and covered call options on securities and indexes, for hedging purposes or to seek to increase returns.

Principal Investment Risks

The value of your investment in the Portfolio will fluctuate, which means you could lose money.

Since the Portfolio focuses its investments in Realty Companies, the Portfolio could lose money due to the performance of real estate-related securities even if securities markets generally are experiencing positive results. The performance of investments made by the Portfolio may be determined to a great extent by the current status of the real estate industry in general, or by other factors (such as interest rates and the availability of loan capital) that may affect the real estate industry, even if other industries would not be so affected. Consequently, the investment strategies of the Portfolio could lead to securities investment results that may be significantly different from investments in securities of other industries or sectors or in a more broad-based portfolio generally.

The risks related to investments in Realty Companies include, but are not limited to: adverse changes in general economic and local market conditions; adverse developments in employment; changes in supply or demand for similar or competing properties; unfavorable changes in applicable taxes, governmental regulations and interest rates; operating or development expenses; and lack of available financing. An investment in REITs may be adversely affected or lost if the REIT fails to comply with applicable laws and regulations. If the Portfolio invests in a REIT that subsequently fails to qualify as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”), it is highly likely that the REIT will be subject to a substantial additional income tax liability that could cause it to liquidate investments, borrow funds under adverse conditions or, possibly, fail.

Many Realty Companies are small and mid cap companies, which carry additional risks because their earnings tend to be less predictable, their share prices more volatile and their securities less liquid than larger, more established companies. The securities of small and mid cap companies tend to trade less frequently than those of larger companies, which can have an adverse effect on the pricing of these securities and on the ability to sell these securities when the Investment Manager deems it appropriate.

There are various risks associated with investing in preferred securities, including credit risk; interest rate risk; deferral and omission of distributions; subordination; call and reinvestment risk; limited liquidity; limited voting rights; and special issuer redemption rights. In addition, unlike common stock, participation in the growth of an issuer may be limited.

• Credit risk is the risk that a security held by the Portfolio will decline in price or the issuer of the security will fail to make dividend, interest or principal payments when due because the issuer experiences a decline in its financial status.

• Interest rate risk is the risk that securities will decline in value because of changes in market interest rates. When market interest rates rise, the market value of such securities generally will fall. Securities with longer periods before maturity may be more sensitive to interest rate changes.

• Preferred securities may include provisions that permit the issuer, at its discretion, to defer or omit distributions for a stated period without any adverse consequences to the issuer.

• Preferred securities are generally subordinated to bonds and other debt instruments in an issuer’s capital structure in terms of having priority to corporate income, claims to corporate assets and liquidation payments, and therefore will be subject to greater credit risk than more senior debt instruments.

• During periods of declining interest rates, an issuer may be able to exercise an option to redeem its issue at par earlier than scheduled, which is generally known as call risk. If this occurs, the Portfolio may be forced to reinvest in lower yielding securities. This is known as reinvestment risk.

• Certain preferred securities may be substantially less liquid than many other securities, such as common stocks or U.S. Government securities. Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by the Portfolio or at prices approximating the value at which the Portfolio is carrying the securities on its books.

• Generally, traditional preferred securities offer no voting rights with respect to the issuer unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may elect a number of directors to the issuer’s board. Generally, once all the arrearages have been paid, the preferred security holders no longer have voting rights. Hybrid-preferred security holders generally have no voting rights.

• In certain varying circumstances, an issuer of preferred securities may redeem the securities prior to a specified date. For instance, for certain types of preferred securities, a redemption may be triggered by a change in U.S. federal income tax or securities laws. As with call provisions, a redemption by the issuer may negatively impact the return of the security held by the Portfolio.

While stocks have historically been a leading choice of long-term investors, they do fluctuate in price, often based on factors unrelated to the issuer’s value, such as investor perception. The market value of a convertible security tends to perform like that of a regular debt security so that, if market interest rates rise, the value of the convertible security falls. Investments in warrants involve certain risks, including the possible lack of a liquid market for resale, price fluctuations and the failure of the price of the underlying security to reach a level at which the warrant can be prudently exercised, in which case the warrant may expire without being exercised and result in a loss of the Portfolio’s entire investment.

While fixed income securities are designed to produce a stable stream of income, their prices move inversely with changes in interest rates. Fixed income securities are subject to credit risk, interest rate risk and call and reinvestment risk as described above for preferred securities. The Portfolio’s investments in lower-rated, higher-yielding securities are subject to greater credit risk than its higher-rated investments. If there is a decline in the credit quality of a fixed income security, or a perception of a decline, the security’s value could fall, potentially lowering the Portfolio’s share price. Junk bonds tend to be more volatile, less liquid and are considered speculative. During unusual market conditions, the Portfolio may not be able to sell certain securities at the time and price it would like.

Non-domestic securities carry special risks, such as exposure to currency fluctuations, less developed or less efficient trading markets, political instability, a lack of company information, differing auditing and legal standards, and, potentially, less liquidity.

Although the Portfolio is not considered to be “non-diversified,” it may invest in a smaller number of issuers than other, more diversified, investment portfolios, and the Portfolio’s net asset value (“NAV”) may be more vulnerable to changes in the market value of a single issuer or group of issuers and may be relatively more susceptible to adverse effects from any single corporate, industry, economic, market, political or regulatory occurrence than if the Portfolio’s investments consisted of securities issued by a larger number of issuers.

Writing options on securities and indexes, including for hedging purposes, may reduce returns or increase volatility, perhaps substantially, and may cause the Portfolio to experience losses greater than if the Portfolio had not engaged in such transactions. Writing options is subject to many of the risks of, and can be highly sensitive to changes in the value of, the related security or index. As such, a small commitment to written options could potentially have a relatively large impact on the Portfolio’s performance. Purchasing options will reduce returns by the amount of premiums paid for options that are not exercised. Over-the-counter options purchased on securities and indexes are subject to the risk of default by the counterparty and can be illiquid.

Any investments in other investment companies and ETFs are subject to the risks of the investments of the investment companies and ETFs, as well as to the general risks of investing in investment companies and ETFs. Portfolio shares will bear not only the Portfolio’s management fees and operating expenses, but also their proportional share of the management fees and operating expenses of any other investment companies and ETFs in which the Portfolio invests.

Portfolio Turnover

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 and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the portfolio turnover rate of the Predecessor Realty Equity Fund (defined below) was 91.2% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Portfolio invests at least 80% of its assets in equity securities (including common, convertible and preferred stocks) of U.S. Realty Companies (defined below), as well as certain synthetic instruments related to U.S. Realty Companies. Such synthetic instruments are investments that have economic characteristics similar to the Portfolio’s direct investments in U.S. Realty Companies and may include warrants, rights, options and shares of ETFs.

The Investment Manager conducts proprietary quantitative, qualitative and on-site real estate analysis to select the Portfolio’s investments, which may include, as appropriate, research at the macroeconomic, sector, company and property level. The Investment Manager’s individual company research may consider a number of quantitative measures, including earnings growth potential, price to earnings or free cash flow multiples, price to net asset value ratios, dividend yield and potential for growth, return on equity and return on assets, as well as qualitative factors such as overall business and growth strategy and quality of management.

The Portfolio may invest in issuers of any market capitalization and securities of any maturity, and the Portfolio’s investments also may include securities purchased in IPOs.

The Portfolio is non-diversified, which means that it may invest a relatively high percentage of its assets in a limited number of issuers, when compared to a diversified fund.

The Portfolio also may invest up to 20% of its assets in equity and fixed income securities and instruments of companies or entities (which need not be U.S. Realty Companies), including, but not limited to, securities of non-U.S. companies and other investment companies.

The Portfolio’s investments in preferred stock and convertible and fixed income securities may include securities which, at the time of purchase, are rated below “investment grade” by an NRSRO, or the unrated equivalent as determined by the Investment Manager (“junk bonds”).

The Portfolio may, but is not required to, write put and covered call options on securities and indexes, for hedging purposes or to seek to increase returns.

Principal Investment Risks

While stocks have historically been a leading choice of long-term investors, they do fluctuate in price, often based on factors unrelated to the issuer’s value, such as investor perception. Preferred stock is subject to credit and interest rate risk (described below) and the risk that the dividend on the stock may be changed or omitted by the issuer and, unlike common stock, participation in the growth of an issuer may be limited. The market value of a convertible security tends to perform like that of a regular debt security so that, if market interest rates rise, the value of the convertible security falls. Investments in warrants involve certain risks, including the possible lack of a liquid market for resale, price fluctuations and the failure of the price of the underlying security to reach a level at which the warrant can be prudently exercised, in which case the warrant may expire without being exercised and result in a loss of the Portfolio’s entire investment. The value of your investment in the Portfolio will fluctuate, which means you could lose money.

Since the Portfolio focuses its investments in Realty Companies, the Portfolio could lose money due to the performance of real estate-related securities even if securities markets generally are experiencing positive results. The performance of investments made by the Portfolio may be determined to a great extent by the current status of the real estate industry in general, or by other factors (such as interest rates and the availability of loan capital) that may affect the real estate industry, even if other industries would not be so affected. Consequently, the investment strategies of the Portfolio could lead to securities investment results that may be significantly different from investments in securities of other industries or sectors or in a more broad-based portfolio generally.

The risks related to investments in Realty Companies include, but are not limited to: adverse changes in general economic and local market conditions; adverse developments in employment; changes in supply or demand for similar or competing properties; unfavorable changes in applicable taxes, governmental regulations and interest rates; operating or development expenses; and lack of available financing.

While fixed income securities are designed to produce a stable stream of income, their prices move inversely with changes in interest rates. Interest rate risk is usually greater for fixed income securities with longer maturities or effective durations. The Portfolio’s investments in lower-rated, higher-yielding securities are subject to greater credit risk than its higher-rated investments. Credit risk is the risk that the issuer will not make interest or principal payments, or will not make payments on a timely basis. If there is a decline, or perceived decline, in the credit quality of a fixed income security (or any guarantor of payment on such security), the security’s value could fall, potentially lowering the Portfolio’s share price. Junk bonds tend to be more volatile, less liquid and are considered speculative. During unusual market conditions, the Portfolio may not be able to sell certain securities at the time and price it would like. Some fixed income securities may give the issuer the option to call, or redeem, the securities before their maturity, and, during a time of declining interest rates, the Portfolio may have to reinvest the proceeds in an investment offering a lower yield (and the Portfolio may not benefit from any increase in the value of its portfolio holdings as a result of declining interest rates).

Non-domestic securities carry special risks, such as exposure to currency fluctuations, less developed or less efficient trading markets, political instability, a lack of company information, differing auditing and legal standards, and, potentially, less liquidity.

Writing options on securities and indexes, including for hedging purposes, may reduce returns or increase volatility, perhaps substantially, and may cause the Portfolio to experience losses greater than if the Portfolio had not engaged in such transactions. Writing options is subject to many of the risks of, and can be highly sensitive to changes in the value of, the related security or index.

Any investments in other investment companies and ETFs are subject to the risks of the investments of the investment companies and ETFs, as well as to the general risks of investing in investment companies and ETFs. Portfolio shares will bear not only the Portfolio’s management fees and operating expenses, but also their proportional share of the management fees and operating expenses of any other investment companies and ETFs in which the Portfolio invests.

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 periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same, giving effect to the fee waiver. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Institutional Shares	133	415
Open Shares	164	508

Portfolio Turnover

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 and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the portfolio turnover rate of the Predecessor International Realty Fund (defined below) was 53.9% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Portfolio invests at least 80% of its assets in equity securities (including common, convertible and preferred stocks) of non-U.S. Realty Companies (defined below), as well as certain synthetic instruments relating to non-U.S. Realty Companies. Such synthetic instruments are investments that have economic characteristics similar to the Portfolio’s direct investments in non-U.S. Realty Companies and may include depositary receipts, including American Depositary Receipts (“ADRs”), Global Depositary Receipts and European Depositary Receipts, warrants, rights, options and shares of ETFs. The Portfolio’s investments in non-U.S. companies may include securities of companies whose principal business activities are located in emerging market countries.

The Investment Manager conducts proprietary quantitative, qualitative and on-site real estate analysis to select the Portfolio’s investments, which may include, as appropriate, research at the macroeconomic, sector, company and property level. The Investment Manager’s individual company research may consider a number of quantitative measures, including earnings growth potential, price to earnings or free cash flow multiples, price to net asset value ratios, dividend yield and potential for growth, return on equity and return on assets, as well as qualitative factors such as overall business and growth strategy and quality of management.

“Realty Companies” are real estate-related companies of any size including, but not limited to, REITs, real estate operating or service companies and companies in the homebuilding, lodging and hotel industries, as well as companies engaged in the healthcare, gaming, retailing, restaurant, natural resources and utility industries, and other companies whose investments, balance sheets or income statements are real-estate intensive (i.e., the company’s actual or anticipated revenues, profits, assets, services or products are related to real estate including, but not limited to, the ownership, renting, leasing, construction, management, development or financing of commercial, industrial or residential real estate).

The Portfolio may invest in issuers of any market capitalization and securities of any maturity, and the Portfolio’s investments also may include securities purchased in IPOs.

The Portfolio is non-diversified, which means that it may invest a relatively high percentage of its assets in a limited number of issuers, when compared to a diversified fund.

The Portfolio also may invest up to 20% of its assets in equity and fixed income securities and instruments of companies or entities (which need not be non-U.S. Realty Companies), including, but not limited to, other investment companies and collective investment funds.

The Portfolio’s investments in preferred stock and convertible and fixed income securities may include securities which, at the time of purchase, are rated below “investment grade” by an NRSRO, or the unrated equivalent as determined by the Investment Manager (“junk bonds”).

The Portfolio may, but is not required to, enter into forward currency contracts and write put and covered call options on securities and indexes, for hedging purposes or to seek to increase returns.

Principal Investment Risks

While stocks have historically been a leading choice of long-term investors, they do fluctuate in price, often based on factors unrelated to the issuer’s value, such as investor perception. Preferred stock is subject to credit and interest rate risk (described below) and the risk that the dividend on the stock may be changed or omitted by the issuer and, unlike common stock, participation in the growth of an issuer may be limited. The market value of a convertible security tends to perform like that of a regular debt security so that, if market interest rates rise, the value of the convertible security falls. Investments in warrants involve certain risks, including the possible lack of a liquid market for resale, price fluctuations and the failure of the price of the underlying security to reach a level at which the warrant can be prudently exercised, in which case the warrant may expire without being exercised and result in a loss of the Portfolio’s entire investment. The value of your investment in the Portfolio will fluctuate, which means you could lose money.

Since the Portfolio focuses its investments in Realty Companies, the Portfolio could lose money due to the performance of real estate-related securities even if securities markets generally are experiencing positive results. The performance of investments made by the Portfolio may be determined to a great extent by the current status of the real estate industry in general, or by other factors (such as interest rates and the availability of loan capital) that may affect the real estate industry, even if other industries would not be so affected. Consequently, the investment strategies of the Portfolio could lead to securities investment results that may be significantly different from investments in securities of other industries or sectors or in a more broad-based portfolio generally.

The risks related to investments in Realty Companies include, but are not limited to: adverse changes in general economic and local market conditions; adverse developments in employment; changes in supply or demand for similar or competing properties; unfavorable changes in applicable taxes, governmental regulations and interest rates; operating or development expenses; and lack of available financing. An investment in REITs may be adversely affected or lost if the REIT fails to comply with applicable laws and regulations. If the Portfolio invests in a REIT that subsequently fails to qualify as a REIT under the Code, it is highly likely that the REIT will be subject to a substantial additional income tax liability that could cause it to liquidate investments, borrow funds under adverse conditions or, possibly, fail.

Many Realty Companies are small and mid cap companies, which carry additional risks because their earnings tend to be less predictable, their share prices more volatile and their securities less liquid than larger, more established companies. The securities of small and mid cap companies tend to trade less frequently than those of larger companies, which can have an adverse effect on the pricing of these securities and on the ability to sell these securities when the Investment Manager deems it appropriate.

Non-domestic securities carry special risks, such as exposure to currency fluctuations, less developed or less efficient trading markets, political instability, a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. The securities markets of emerging market countries can be extremely volatile. The Portfolio’s performance will be influenced by political, social and economic factors affecting companies in emerging market countries. Emerging market countries can generally have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries.

Irrespective of any foreign currency exposure hedging, the Portfolio may experience a decline in the value of its portfolio securities, in U.S. dollar terms, due solely to fluctuations in currency exchange rates.

Because the Portfolio may invest in a smaller number of issuers than other, more diversified, investment portfolios, the Portfolio’s NAV may be more vulnerable to changes in the market value of a single issuer or group of issuers and may be relatively more susceptible to adverse effects from any single corporate, industry, economic, market, political or regulatory occurrence than if the Portfolio’s investments consisted of securities issued by a larger number of issuers.

While fixed income securities are designed to produce a stable stream of income, their prices move inversely with changes in interest rates. Interest rate risk is usually greater for fixed income securities with longer maturities or effective durations. The Portfolio’s investments in lower-rated, higher-yielding securities are subject to greater credit risk than its higher-rated investments. Credit risk is the risk that the issuer will not make interest or principal payments, or will not make payments on a timely basis. If there is a decline, or perceived decline, in the credit quality of a fixed income security (or any guarantor of payment on such security), the security’s value could fall, potentially lowering the Portfolio’s share price. Junk bonds tend to be more volatile, less liquid and are considered speculative. During unusual market conditions, the Portfolio may not be able to sell certain securities at the time and price it would like. Some fixed income securities may give the issuer the option to call, or redeem, the securities before their maturity, and, during a time of declining interest rates, the Portfolio may have to reinvest the proceeds in an investment offering a lower yield (and the Portfolio may not benefit from any increase in the value of its portfolio holdings as a result of declining interest rates).

Writing options on securities and indexes, including for hedging purposes, may reduce returns or increase volatility, perhaps substantially, and may cause the Portfolio to experience losses greater than if the Portfolio had not engaged in such transactions. Writing options is subject to many of the risks of, and can be highly sensitive to changes in the value of, the related security or index. As such, a small commitment to written options could potentially have a relatively large impact on the Portfolio’s performance. Purchasing options will reduce returns by the amount of premiums paid for options that are not exercised. Over-the-counter options purchased on securities and indexes are subject to the risk of default by the counterparty and can be illiquid.

Any investments in other investment companies, collective investment funds and ETFs are subject to the risks of the investments of the investment companies, collective investment funds and ETFs, as well as to the general risks of investing in investment companies, collective investment funds and ETFs. Portfolio shares will bear not only the Portfolio’s management fees and operating expenses, but also their proportional share of the management fees and operating expenses of the other investment companies, collective investment funds and ETFs in which the Portfolio invests.

Under normal circumstances, the Portfolio invests at least 80% of its assets in dividend-paying common and preferred stocks, convertible securities and fixed income securities of U.S. Realty Companies (defined below), as well as certain synthetic instruments related to U.S. Realty Companies. Such synthetic instruments are investments that have economic characteristics similar to the Portfolio’s direct investments in U.S. Realty Companies and may include warrants, rights, options and shares of exchange-traded funds (“ETFs”).

The Investment Manager focuses on investments having the potential to deliver regular income and to offer the opportunity for long-term growth and capital appreciation. The Investment Manager conducts proprietary quantitative, qualitative and on-site real estate analysis to select the Portfolio’s investments, which may include, as appropriate, research at the macroeconomic, sector, company and property level. The Investment Manager’s individual company research may consider a number of quantitative measures, including earnings growth potential, price to earnings or free cash flow multiples, price to net asset value ratios, dividend yield and potential for growth, return on equity and return on assets, as well as qualitative factors such as overall business and growth strategy and quality of management.

“Realty Companies” are real estate-related companies of any size including, but not limited to, real estate investment trusts (“REITs”), real estate operating or service companies and companies in the homebuilding, lodging and hotel industries, as well as companies engaged in the healthcare, gaming, retailing, restaurant, natural resources and utility industries, and other companies whose investments, balance sheets or income statements are real-estate intensive (i.e., the company’s actual or anticipated revenues, profits, assets, services or products are related to real estate including, but not limited to, the ownership, renting, leasing, construction, management, development or financing of commercial, industrial or residential real estate).

The Portfolio’s investments in preferred stock and convertible and fixed income securities may include securities which, at the time of purchase, are rated below “investment grade” by a nationally recognized statistical rating organization (“NRSRO”), or the unrated equivalent as determined by the Investment Manager (“junk bonds”).

The Portfolio may invest in issuers of any market capitalization and securities of any maturity, and the Portfolio’s investments also may include securities purchased in initial public offerings (“IPOs”).

The Portfolio also may invest up to 25% of its net assets in companies organized as master limited partnerships and their affiliates.

The Portfolio also may invest up to 20% of its assets in other securities and instruments of companies or entities (which need not be U.S. Realty Companies), including, but not limited to, securities of non-U.S. companies and other investment companies.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The value of your investment in the Portfolio will fluctuate, which means you could lose money.

Since the Portfolio focuses its investments in Realty Companies, the Portfolio could lose money due to the performance of real estate-related securities even if securities markets generally are experiencing positive results. The performance of investments made by the Portfolio may be determined to a great extent by the current status of the real estate industry in general, or by other factors (such as interest rates and the availability of loan capital) that may affect the real estate industry, even if other industries would not be so affected. Consequently, the investment strategies of the Portfolio could lead to securities investment results that may be significantly different from investments in securities of other industries or sectors or in a more broad-based portfolio generally.

The risks related to investments in Realty Companies include, but are not limited to: adverse changes in general economic and local market conditions; adverse developments in employment; changes in supply or demand for similar or competing properties; unfavorable changes in applicable taxes, governmental regulations and interest rates; operating or development expenses; and lack of available financing. An investment in REITs may be adversely affected or lost if the REIT fails to comply with applicable laws and regulations. If the Portfolio invests in a REIT that subsequently fails to qualify as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”), it is highly likely that the REIT will be subject to a substantial additional income tax liability that could cause it to liquidate investments, borrow funds under adverse conditions or, possibly, fail.

Many Realty Companies are small and mid cap companies, which carry additional risks because their earnings tend to be less predictable, their share prices more volatile and their securities less liquid than larger, more established companies. The securities of small and mid cap companies tend to trade less frequently than those of larger companies, which can have an adverse effect on the pricing of these securities and on the ability to sell these securities when the Investment Manager deems it appropriate.

There are various risks associated with investing in preferred securities, including credit risk; interest rate risk; deferral and omission of distributions; subordination; call and reinvestment risk; limited liquidity; limited voting rights; and special issuer redemption rights. In addition, unlike common stock, participation in the growth of an issuer may be limited.

• Credit risk is the risk that a security held by the Portfolio will decline in price or the issuer of the security will fail to make dividend, interest or principal payments when due because the issuer experiences a decline in its financial status.

• Interest rate risk is the risk that securities will decline in value because of changes in market interest rates. When market interest rates rise, the market value of such securities generally will fall. Securities with longer periods before maturity may be more sensitive to interest rate changes.

• Preferred securities may include provisions that permit the issuer, at its discretion, to defer or omit distributions for a stated period without any adverse consequences to the issuer.

• Preferred securities are generally subordinated to bonds and other debt instruments in an issuer’s capital structure in terms of having priority to corporate income, claims to corporate assets and liquidation payments, and therefore will be subject to greater credit risk than more senior debt instruments.

• During periods of declining interest rates, an issuer may be able to exercise an option to redeem its issue at par earlier than scheduled, which is generally known as call risk. If this occurs, the Portfolio may be forced to reinvest in lower yielding securities. This is known as reinvestment risk.

• Certain preferred securities may be substantially less liquid than many other securities, such as common stocks or U.S. Government securities. Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by the Portfolio or at prices approximating the value at which the Portfolio is carrying the securities on its books.

• Generally, traditional preferred securities offer no voting rights with respect to the issuer unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may elect a number of directors to the issuer’s board. Generally, once all the arrearages have been paid, the preferred security holders no longer have voting rights. Hybrid-preferred security holders generally have no voting rights.

• In certain varying circumstances, an issuer of preferred securities may redeem the securities prior to a specified date. For instance, for certain types of preferred securities, a redemption may be triggered by a change in U.S. federal income tax or securities laws. As with call provisions, a redemption by the issuer may negatively impact the return of the security held by the Portfolio.

While stocks have historically been a leading choice of long-term investors, they do fluctuate in price, often based on factors unrelated to the issuer’s value, such as investor perception. The market value of a convertible security tends to perform like that of a regular debt security so that, if market interest rates rise, the value of the convertible security falls. Investments in warrants involve certain risks, including the possible lack of a liquid market for resale, price fluctuations and the failure of the price of the underlying security to reach a level at which the warrant can be prudently exercised, in which case the warrant may expire without being exercised and result in a loss of the Portfolio’s entire investment.

While fixed income securities are designed to produce a stable stream of income, their prices move inversely with changes in interest rates. Fixed income securities are subject to credit risk, interest rate risk and call and reinvestment risk as described above for preferred securities. The Portfolio’s investments in lower-rated, higher-yielding securities are subject to greater credit risk than its higher-rated investments. If there is a decline in the credit quality of a fixed income security, or a perception of a decline, the security’s value could fall, potentially lowering the Portfolio’s share price. Junk bonds tend to be more volatile, less liquid and are considered speculative. During unusual market conditions, the Portfolio may not be able to sell certain securities at the time and price it would like.

Non-domestic securities carry special risks, such as exposure to currency fluctuations, less developed or less efficient trading markets, political instability, a lack of company information, differing auditing and legal standards, and, potentially, less liquidity.

Although the Portfolio is not considered to be “non-diversified,” it may invest in a smaller number of issuers than other, more diversified, investment portfolios, and the Portfolio’s net asset value (“NAV”) may be more vulnerable to changes in the market value of a single issuer or group of issuers and may be relatively more susceptible to adverse effects from any single corporate, industry, economic, market, political or regulatory occurrence than if the Portfolio’s investments consisted of securities issued by a larger number of issuers.

Writing options on securities and indexes, including for hedging purposes, may reduce returns or increase volatility, perhaps substantially, and may cause the Portfolio to experience losses greater than if the Portfolio had not engaged in such transactions. Writing options is subject to many of the risks of, and can be highly sensitive to changes in the value of, the related security or index. As such, a small commitment to written options could potentially have a relatively large impact on the Portfolio’s performance. Purchasing options will reduce returns by the amount of premiums paid for options that are not exercised. Over-the-counter options purchased on securities and indexes are subject to the risk of default by the counterparty and can be illiquid.

Any investments in other investment companies and ETFs are subject to the risks of the investments of the investment companies and ETFs, as well as to the general risks of investing in investment companies and ETFs. Portfolio shares will bear not only the Portfolio’s management fees and operating expenses, but also their proportional share of the management fees and operating expenses of any other investment companies and ETFs in which the Portfolio invests.

These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Portfolio’s performance.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests at least 80% of its assets in equity securities (including common, convertible and preferred stocks) of U.S. Realty Companies (defined below), as well as certain synthetic instruments related to U.S. Realty Companies. Such synthetic instruments are investments that have economic characteristics similar to the Portfolio’s direct investments in U.S. Realty Companies and may include warrants, rights, options and shares of ETFs.

The Investment Manager conducts proprietary quantitative, qualitative and on-site real estate analysis to select the Portfolio’s investments, which may include, as appropriate, research at the macroeconomic, sector, company and property level. The Investment Manager’s individual company research may consider a number of quantitative measures, including earnings growth potential, price to earnings or free cash flow multiples, price to net asset value ratios, dividend yield and potential for growth, return on equity and return on assets, as well as qualitative factors such as overall business and growth strategy and quality of management.

“Realty Companies” are real estate-related companies of any size including, but not limited to, REITs, real estate operating or service companies and companies in the homebuilding, lodging and hotel industries, as well as companies engaged in the healthcare, gaming, retailing, restaurant, natural resources and utility industries, and other companies whose investments, balance sheets or income statements are real-estate intensive (i.e. the company’s actual or anticipated revenues, profits, assets, services or products are related to real estate including, but not limited to, the ownership, renting, leasing, construction, management, development or financing of commercial, industrial or residential real estate).

The Portfolio may invest in issuers of any market capitalization and securities of any maturity, and the Portfolio’s investments also may include securities purchased in IPOs.

The Portfolio is non-diversified, which means that it may invest a relatively high percentage of its assets in a limited number of issuers, when compared to a diversified fund.

The Portfolio also may invest up to 20% of its assets in equity and fixed income securities and instruments of companies or entities (which need not be U.S. Realty Companies), including, but not limited to, securities of non-U.S. companies and other investment companies.

The Portfolio’s investments in preferred stock and convertible and fixed income securities may include securities which, at the time of purchase, are rated below “investment grade” by an NRSRO, or the unrated equivalent as determined by the Investment Manager (“junk bonds”).

The Portfolio may, but is not required to, write put and covered call options on securities and indexes, for hedging purposes or to seek to increase returns.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

While stocks have historically been a leading choice of long-term investors, they do fluctuate in price, often based on factors unrelated to the issuer’s value, such as investor perception. Preferred stock is subject to credit and interest rate risk (described below) and the risk that the dividend on the stock may be changed or omitted by the issuer and, unlike common stock, participation in the growth of an issuer may be limited. The market value of a convertible security tends to perform like that of a regular debt security so that, if market interest rates rise, the value of the convertible security falls. Investments in warrants involve certain risks, including the possible lack of a liquid market for resale, price fluctuations and the failure of the price of the underlying security to reach a level at which the warrant can be prudently exercised, in which case the warrant may expire without being exercised and result in a loss of the Portfolio’s entire investment. The value of your investment in the Portfolio will fluctuate, which means you could lose money.

Since the Portfolio focuses its investments in Realty Companies, the Portfolio could lose money due to the performance of real estate-related securities even if securities markets generally are experiencing positive results. The performance of investments made by the Portfolio may be determined to a great extent by the current status of the real estate industry in general, or by other factors (such as interest rates and the availability of loan capital) that may affect the real estate industry, even if other industries would not be so affected. Consequently, the investment strategies of the Portfolio could lead to securities investment results that may be significantly different from investments in securities of other industries or sectors or in a more broad-based portfolio generally.

The risks related to investments in Realty Companies include, but are not limited to: adverse changes in general economic and local market conditions; adverse developments in employment; changes in supply or demand for similar or competing properties; unfavorable changes in applicable taxes, governmental regulations and interest rates; operating or development expenses; and lack of available financing. An investment in REITs may be adversely affected or lost if the REIT fails to comply with applicable laws and regulations. If the Portfolio invests in a REIT that subsequently fails to qualify as a REIT under the Code, it is highly likely that the REIT will be subject to a substantial additional income tax liability that could cause it to liquidate investments, borrow funds under adverse conditions or, possibly, fail.

Many Realty Companies are small and mid cap companies, which carry additional risks because their earnings tend to be less predictable, their share prices more volatile and their securities less liquid than larger, more established companies. The securities of small and mid cap companies tend to trade less frequently than those of larger companies, which can have an adverse effect on the pricing of these securities and on the ability to sell these securities when the Investment Manager deems it appropriate.

Because the Portfolio may invest in a smaller number of issuers than other, more diversified, investment portfolios, the Portfolio’s NAV may be more vulnerable to changes in the market value of a single issuer or group of issuers and may be relatively more susceptible to adverse effects from any single corporate, industry, economic, market, political or regulatory occurrence than if the Portfolio’s investments consisted of securities issued by a larger number of issuers.

While fixed income securities are designed to produce a stable stream of income, their prices move inversely with changes in interest rates. Interest rate risk is usually greater for fixed income securities with longer maturities or effective durations. The Portfolio’s investments in lower-rated, higher-yielding securities are subject to greater credit risk than its higher-rated investments. Credit risk is the risk that the issuer will not make interest or principal payments, or will not make payments on a timely basis. If there is a decline, or perceived decline, in the credit quality of a fixed income security (or any guarantor of payment on such security), the security’s value could fall, potentially lowering the Portfolio’s share price. Junk bonds tend to be more volatile, less liquid and are considered speculative. During unusual market conditions, the Portfolio may not be able to sell certain securities at the time and price it would like. Some fixed income securities may give the issuer the option to call, or redeem, the securities before their maturity, and, during a time of declining interest rates, the Portfolio may have to reinvest the proceeds in an investment offering a lower yield (and the Portfolio may not benefit from any increase in the value of its portfolio holdings as a result of declining interest rates).

Non-domestic securities carry special risks, such as exposure to currency fluctuations, less developed or less efficient trading markets, political instability, a lack of company information, differing auditing and legal standards, and, potentially, less liquidity.

Writing options on securities and indexes, including for hedging purposes, may reduce returns or increase volatility, perhaps substantially, and may cause the Portfolio to experience losses greater than if the Portfolio had not engaged in such transactions. Writing options is subject to many of the risks of, and can be highly sensitive to changes in the value of, the related security or index. As such, a small commitment to written options could potentially have a relatively large impact on the Portfolio’s performance. Purchasing options will reduce returns by the amount of premiums paid for options that are not exercised. Over-the-counter options purchased on securities and indexes are subject to the risk of default by the counterparty and can be illiquid.

Any investments in other investment companies and ETFs are subject to the risks of the investments of the investment companies and ETFs, as well as to the general risks of investing in investment companies and ETFs. Portfolio shares will bear not only the Portfolio’s management fees and operating expenses, but also their proportional share of the management fees and operating expenses of any other investment companies and ETFs in which the Portfolio invests.

Under normal circumstances, the Portfolio invests at least 80% of its assets in equity securities (including common, convertible and preferred stocks) of non-U.S. Realty Companies (defined below), as well as certain synthetic instruments relating to non-U.S. Realty Companies. Such synthetic instruments are investments that have economic characteristics similar to the Portfolio’s direct investments in non-U.S. Realty Companies and may include depositary receipts, including American Depositary Receipts (“ADRs”), Global Depositary Receipts and European Depositary Receipts, warrants, rights, options and shares of ETFs. The Portfolio’s investments in non-U.S. companies may include securities of companies whose principal business activities are located in emerging market countries.

The Investment Manager conducts proprietary quantitative, qualitative and on-site real estate analysis to select the Portfolio’s investments, which may include, as appropriate, research at the macroeconomic, sector, company and property level. The Investment Manager’s individual company research may consider a number of quantitative measures, including earnings growth potential, price to earnings or free cash flow multiples, price to net asset value ratios, dividend yield and potential for growth, return on equity and return on assets, as well as qualitative factors such as overall business and growth strategy and quality of management.

“Realty Companies” are real estate-related companies of any size including, but not limited to, REITs, real estate operating or service companies and companies in the homebuilding, lodging and hotel industries, as well as companies engaged in the healthcare, gaming, retailing, restaurant, natural resources and utility industries, and other companies whose investments, balance sheets or income statements are real-estate intensive (i.e., the company’s actual or anticipated revenues, profits, assets, services or products are related to real estate including, but not limited to, the ownership, renting, leasing, construction, management, development or financing of commercial, industrial or residential real estate).

The Portfolio may invest in issuers of any market capitalization and securities of any maturity, and the Portfolio’s investments also may include securities purchased in IPOs.

The Portfolio is non-diversified, which means that it may invest a relatively high percentage of its assets in a limited number of issuers, when compared to a diversified fund.

The Portfolio also may invest up to 20% of its assets in equity and fixed income securities and instruments of companies or entities (which need not be non-U.S. Realty Companies), including, but not limited to, other investment companies and collective investment funds.

The Portfolio’s investments in preferred stock and convertible and fixed income securities may include securities which, at the time of purchase, are rated below “investment grade” by an NRSRO, or the unrated equivalent as determined by the Investment Manager (“junk bonds”).

The value of your investment in the Portfolio will fluctuate, which means you could lose money.

Since the Portfolio focuses its investments in Realty Companies, the Portfolio could lose money due to the performance of real estate-related securities even if securities markets generally are experiencing positive results. The performance of investments made by the Portfolio may be determined to a great extent by the current status of the real estate industry in general, or by other factors (such as interest rates and the availability of loan capital) that may affect the real estate industry, even if other industries would not be so affected. Consequently, the investment strategies of the Portfolio could lead to securities investment results that may be significantly different from investments in securities of other industries or sectors or in a more broad-based portfolio generally.

The risks related to investments in Realty Companies include, but are not limited to: adverse changes in general economic and local market conditions; adverse developments in employment; changes in supply or demand for similar or competing properties; unfavorable changes in applicable taxes, governmental regulations and interest rates; operating or development expenses; and lack of available financing.

If the Portfolio invests in a REIT that subsequently fails to qualify as a REIT under the Code, it is highly likely that the REIT will be subject to a substantial additional income tax liability that could cause it to liquidate investments, borrow funds under adverse conditions or, possibly, fail.

Many Realty Companies are small and mid cap companies, which carry additional risks because their earnings tend to be less predictable, their share prices more volatile and their securities less liquid than larger, more established companies. The securities of small and mid cap companies tend to trade less frequently than those of larger companies, which can have an adverse effect on the pricing of these securities and on the ability to sell these securities when the Investment Manager deems it appropriate.

Non-domestic securities carry special risks, such as exposure to currency fluctuations, less developed or less efficient trading markets, political instability, a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. The securities markets of emerging market countries can be extremely volatile. The Portfolio’s performance will be influenced by political, social and economic factors affecting companies in emerging market countries. Emerging market countries can generally have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries.

Irrespective of any foreign currency exposure hedging, the Portfolio may experience a decline in the value of its portfolio securities, in U.S. dollar terms, due solely to fluctuations in currency exchange rates.

Because the Portfolio may invest in a smaller number of issuers than other, more diversified, investment portfolios, the Portfolio’s NAV may be more vulnerable to changes in the market value of a single issuer or group of issuers and may be relatively more susceptible to adverse effects from any single corporate, industry, economic, market, political or regulatory occurrence than if the Portfolio’s investments consisted of securities issued by a larger number of issuers.

While fixed income securities are designed to produce a stable stream of income, their prices move inversely with changes in interest rates. Interest rate risk is usually greater for fixed income securities with longer maturities or effective durations. The Portfolio’s investments in lower-rated, higher-yielding securities are subject to greater credit risk than its higher-rated investments. Credit risk is the risk that the issuer will not make interest or principal payments, or will not make payments on a timely basis. If there is a decline, or perceived decline, in the credit quality of a fixed income security (or any guarantor of payment on such security), the security’s value could fall, potentially lowering the Portfolio’s share price. Junk bonds tend to be more volatile, less liquid and are considered speculative. During unusual market conditions, the Portfolio may not be able to sell certain securities at the time and price it would like. Some fixed income securities may give the issuer the option to call, or redeem, the securities before their maturity, and, during a time of declining interest rates, the Portfolio may have to reinvest the proceeds in an investment offering a lower yield (and the Portfolio may not benefit from any increase in the value of its portfolio holdings as a result of declining interest rates).

Writing options on securities and indexes, including for hedging purposes, may reduce returns or increase volatility, perhaps substantially, and may cause the Portfolio to experience losses greater than if the Portfolio had not engaged in such transactions. Writing options is subject to many of the risks of, and can be highly sensitive to changes in the value of, the related security or index. As such, a small commitment to written options could potentially have a relatively large impact on the Portfolio’s performance. Purchasing options will reduce returns by the amount of premiums paid for options that are not exercised. Over-the-counter options purchased on securities and indexes are subject to the risk of default by the counterparty and can be illiquid.

Any investments in other investment companies, collective investment funds and ETFs are subject to the risks of the investments of the investment companies, collective investment funds and ETFs, as well as to the general risks of investing in investment companies, collective investment funds and ETFs. Portfolio shares will bear not only the Portfolio’s management fees and operating expenses, but also their proportional share of the management fees and operating expenses of the other investment companies, collective investment funds and ETFs in which the Portfolio invests.
