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. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example Lazard U.S. Mid Cap Equity Portfolio (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional Shares	95	296	515	1,143
Open Shares	121	378	654	1,443

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’s portfolio turnover rate was 83% of the average value of its portfolio.

Principal Investment Strategies

The Portfolio invests primarily in equity securities, principally common stocks, of mid cap U.S. companies that the Investment Manager believes are undervalued based on their earnings, cash flow or asset values. The Investment Manager considers “mid cap companies” to be those companies that, at the time of initial purchase by the Portfolio, have market capitalizations within the range of companies included in the Russell Midcap® Index (ranging from approximately $123.9 million to $22.8 billion as of April 2, 2012).

Under normal circumstances, the Portfolio invests at least 80% of its assets in equity securities of medium-size (mid cap) U.S. companies. The Portfolio may invest up to 20% of its assets in equity securities of larger or smaller U.S. companies. The Portfolio also may invest up to 15% of its assets in equity securities of non-U.S. companies, including ADRs and GDRs.

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

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.

The Portfolio invests in stocks believed by the Investment Manager to be undervalued, but that may not realize their perceived value for extended periods of time or may never realize their perceived value. The stocks in which the Portfolio invests may respond differently to market and other developments than other types of stocks.

Non-U.S. 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. In addition, investments denominated in currencies other than U.S. dollars carry the risk that such currencies will decline in value relative to the U.S. dollar and affect the value of these investments held in the Portfolio.
