Important Disclosures:

The net asset value of shares of a closed-end fund may not always correspond to the market price of such shares. Common stock of many closed-end funds frequently trade at a discount from their net asset value. The LaSalle Closed-End Fund is subject to stock market risk, which is the risk that stock prices overall will decline over short or long periods, adversely affecting the value of an investment in the LaSalle Closed-End Fund.

Investments in real estate securities may be subject to specific risks, such as the risks associated with general and local economic conditions, and the risks related to individual properties. Investing in one economic sector, such as real estate, may result in greater price fluctuations than owning a portfolio of diversified investments.

Investments in foreign securities involve certain risks not associated with investments in U.S. companies, including the risks of a particular country, including the political, regulatory, economic, social and other conditions of the country, as well as fluctuations in its currency and the risks associated with less developed custody and settlement practices. For emerging markets, these risks are even greater.

Distributions paid to stockholders are subject to recharacterization for tax purposes because the securities (e.g., real estate investment trusts) in which the funds invest may not provide complete tax information to the funds as to the tax character of the dividends distributed by such company (e.g., income, capital gain or return of capital) until after the funds have made distributions to stockholders. This recharacterization could result in a proportionate increase in returns of capital to stockholders. In certain situations, returns of capital could be taxable for federal income tax purposes, and all or a portion of a fund’s capital loss carryforwards from prior years could effectively be forfeited.

There is no guarantee that a fund’s investment goals/objectives will be met or that distributions will be made, and you could lose money.
