Lazard Retirement Emerging Markets Equity Portfolio

Investment Objective

The Portfolio seeks long-term capital appreciation.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Portfolio, a series of Lazard Retirement Series, Inc., but does not reflect the fees or charges imposed by the separate accounts of certain insurance companies (the “Participating Insurance Companies”) under variable annuity contracts or variable life insurance policies (the “Policies” and each, a “Policy”). If such fees and charges were reflected, the figures in the table would be higher.

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 hold or 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 expense limitation agreement in year one only. The Example does not reflect fees and expenses imposed by the Participating Insurance Companies under the Policies; if they were reflected, the figures in the Example would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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. 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’s portfolio turnover rate was 30% 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 of companies whose principal business activities are located in emerging market countries. The Portfolio invests primarily in equity securities, principally common stocks, of non-U.S. companies whose principal activities are located in emerging market countries and that Lazard Asset Management LLC (the “Investment Manager”) believes are undervalued based on their earnings, cash flow or asset values. In addition to common stocks, such equity securities also may include American Depositary Receipts (“ADRs”), Global Depositary Receipts and European Depositary Receipts. Emerging market countries include all countries represented by the MSCI Emerging Markets Index, which currently includes: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Kuwait, Malaysia, Mexico, Peru, Philippines, Poland, Qatar, Saudi Arabia, South Africa, Taiwan, Thailand, Turkey and United Arab Emirates.

In addition, implementation of the Portfolio’s investment strategy may, during certain periods, result in the investment of a significant portion of the Portfolio’s assets in a particular market sector.

Principal Investment Risks

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

Market Risk: The Portfolio may incur losses due to declines in one or more markets in which it invests. These declines may be the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s). To the extent that such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio’s investments in such industries, market sectors, countries and/or geographic regions can be expected to be particularly affected, especially if such investments are a significant portion of its investment portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war or military conflict, acts of terrorism, the spread of infectious illness or other public health issues, social unrest, natural disasters, extreme weather, other geological events, man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, the imposition of sanctions or other similar measures, recessions or other events could have a significant negative impact on global economic and market conditions. For example, a public health or other emergency and aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, may have severe negative impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio’s securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures taken in response to such actions), or the threat or potential of one or more such events and developments, could lead to price volatility and overall declines in the U.S. and global investment markets.

Issuer Risk: The value of a security may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets or factors unrelated to the issuer’s value, such as investor perception.

Non-U.S. Securities Risk: The Portfolio’s performance will be influenced by political, social and economic factors affecting the non-U.S. countries and companies in which the Portfolio invests. Non-U.S. securities carry special risks, such as less developed or less efficient trading markets, political instability, a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. Non-U.S. securities may also subject the Portfolio’s investments to changes in currency rates, which can make the return on an investment increase or decrease, unrelated to the quality or performance of the investment itself. Non-U.S. securities may be subject to economic sanctions or other

Summary Prospectus

2

governmental actions or developments, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) or problems related to share registration, trade settlement or asset custody, which could, among other things, effectively restrict or eliminate the Portfolio’s ability to purchase or sell certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities may become worthless. In addition, as a result of trade restrictions (including tariffs) and other similar governmental actions or developments, the Portfolio may be forced to sell or otherwise dispose of foreign investments at inopportune times or prices.

Emerging Market Risk: Emerging market countries generally have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries. The economies of countries with emerging markets may be based predominantly on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme debt burdens or volatile inflation rates. Further, investments in securities of issuers located in certain emerging countries involve the risk of loss resulting from problems in share registration, settlement or custody, substantial economic, political and social disruptions and the threat or imposition of sanctions or exchange controls (including repatriation restrictions). The securities markets of emerging market countries have historically been extremely volatile and less liquid than more developed markets, thus, the Portfolio may be unable to liquidate its positions in such securities at a favorable time or price. These market conditions may continue or worsen. Investments in these countries may be subject to political, economic, legal, market and currency risks. Significant devaluation of emerging market currencies against the U.S. dollar may occur subsequent to acquisition of investments denominated in emerging market currencies. Emerging market countries may also be more susceptible to fraud, corruption, and money laundering, which may result in negative commercial consequences in relation to the value, liquidity and tradability of investments in or related to those regions.

Foreign Currency Risk: Investments denominated in currencies other than U.S. dollars may experience a decline in value, in U.S. dollar terms, due solely to fluctuations in currency exchange rates. The Portfolio’s investments denominated in such currencies (particularly currencies of emerging markets countries), as well as any investments in currencies themselves, could be adversely affected by delays in, or a refusal to grant, repatriation of funds or conversion of currencies. 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. The Investment Manager does not intend to utilize foreign currency contracts for the purpose of generating investment returns.

Depositary Receipts Risk: ADRs and similar depositary receipts typically will be subject to certain of the risks associated with direct investments in the securities of non-U.S. companies, because their values depend on the performance of the underlying non-U.S. securities. However, currency fluctuations will impact investments in depositary receipts differently than direct investments in non-U.S. dollar-denominated non-U.S. securities, because a depositary receipt will not appreciate in value solely as a result of appreciation in the currency in which the underlying non-U.S. dollar security is denominated.

Large Cap Companies Risk: Investments in large cap companies may underperform other segments of the market when such other segments are in favor or because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain high growth rates during periods of economic expansion.

Small and Mid Cap Companies Risk: Small and mid cap companies 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 shares 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.

Value Investing Risk: Value investments are believed by the Investment Manager to be undervalued, but may not realize their perceived value for extended periods of time or may never realize their perceived value. These securities may respond differently to market and other developments than other types of securities.

Sector Risk: Implementation of the Portfolio’s investment strategy may, during certain periods, result in the investment of a significant portion of the Portfolio’s assets in a particular market sector, such as companies in the financials sector, and the Portfolio would be expected to be affected by developments in that sector.

Summary Prospectus

Financials. Companies in the financials sector can be significantly affected by, among other things: government regulation; changes in interest rates and/or monetary policy and general economic conditions; the availability and cost of capital; capital requirements; decreased liquidity in credit markets; and the rate of defaults on corporate, consumer and government debt.

Securities Selection Risk: Securities and other investments selected by the Investment Manager for the Portfolio may not perform to expectations. This could result in the Portfolio’s underperformance compared to other funds with similar investment objectives or strategies.
