LMP Real Estate Income Fund Inc. (NYSE: RIT) (the “Fund”) today announced that the Fund’s Board of Directors approved the conversion of the Fund from a closed-end fund to an open-end fund through a merger with and into ClearBridge Real Estate Opportunities Fund (“CRO”), a series of Legg Mason Funds Trust (“LM Trust”) (the “Merger”). LM Trust is newly organized and expects to register as an open-end management investment company under the Investment Company Act of 1940, as amended. The Merger will require the approval of the Fund’s stockholders. If approved by stockholders of the Fund, the Merger is anticipated to occur during the second quarter of 2016. If the Merger is consummated, stockholders of the Fund will become holders of Class O shares of CRO and will have the ability to redeem their shares at net asset value, subject to certain conditions including the imposition of a redemption fee of 1% for one year after the Merger.

The Fund and CRO have different investment objectives, but similar investment policies and strategies. The Fund’s primary investment objective is high current income with capital appreciation as a secondary investment objective. CRO’s primary investment objective is total return. CRO is expected to invest in a broader universe of real estate and real estate-related companies.

As previously announced, Bulldog Investors, LLC (“Bulldog”) and the Fund have entered into a Settlement Agreement following a protracted proxy contest pursuant to which Bulldog has agreed vote in favor of (i) the Merger, (ii) any routine management proposal, including a proposal relating to the election of directors or selection of auditors and (iii) the Board of Director’s recommendation on any proposal submitted by a stockholder.

A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and incorporated by reference herein.

In connection with the Merger, the Fund and LM Trust intend to file a proxy statement/prospectus on Form N-14 with the Securities and Exchange Commission (“SEC”). Investors are advised to read the proxy statement/prospectus when it becomes available because it will contain important information. When filed with the SEC, the proxy statement/prospectus and other documents filed will be available free of charge at the SEC’s website, http://www.sec.gov. Stockholders can also obtain copies of these documents, when available, for free by calling the Fund at 1-888-777-0102.

The Fund, its directors and executive officers and the Fund’s investment adviser, members of its management and employees may be deemed to be participants in the Fund’s solicitation of proxies from its stockholders in connection with the proposed merger. Information concerning the interests of the participants in the solicitation will be set forth in the Fund’s proxy statement and stockholder reports on Form N-CSR, to be filed with the SEC.
