At the Annual Meeting, the holders of 27,097,821 shares of the Company’s common stock, which represents approximately 95% of the shares of the Company’s common stock outstanding and entitled to vote as of the record date for the Annual Meeting of March 25, 2013, were represented in person or by proxy. The voting results of the Annual Meeting are set forth below.

Proposal 1 – Election of Directors – The Company’s stockholders elected James A. Moore, Philip A. Brooks and Ronald A. Malone to each serve as a director of the Company for three-year terms expiring in 2016. The voting results for each of these individuals were as follows:

Proposal 3 – Advisory Vote on Executive Compensation – The Company’s stockholders approved, on an advisory (non-binding) basis, the compensation of the Company’s named executive officers, as disclosed in the Proxy Statement in accordance with the compensation disclosure rules of the SEC.

Item 7.01 Regulation FD Disclosure.

On May 28, 2013, the Company issued a press release announcing the launch of its new branding strategy that involves an integrated marketing program inclusive of a refreshed corporate logo, enhanced marketing content, new responsive website and a new color palette and image scheme. A copy of the Company’s press release is attached as Exhibit 99.1 to this Current Report on

Form 8-K.

Attached hereto as Exhibit 99.2 is an updated slideshow presentation of the Company.

The information being furnished under Item 7.01, Exhibit 99.1, and Exhibit 99.2 shall not be deemed “filed” for purposes of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing. The press release and the presentation contain, and may implicate, forward-looking statements regarding the Company and include cautionary statements identifying important factors that could cause actual results to differ materially from those anticipated.

In the presentation, the Company’s management utilized non-GAAP financial measures to describe the Company’s adjusted EBITDAR, adjusted CFFO, adjusted CFFO per share and other items. These non-GAAP financial measures are used by management to evaluate financial performance and resource allocation for its facilities and for the Company as a whole. These measures are commonly used as an analytical indicator within the senior housing industry, and also serve as a measure of leverage capacity and debt service ability. The Company has provided this information in order to enhance investors overall understanding of the Company’s financial performance and prospects. In addition, because the Company has historically provided this type of information to the investment community, the Company believes that including this information provides consistency in its financial reporting.

These non-GAAP financial measures should not be considered as measures of financial performance under generally accepted accounting principles, and items excluded from them are significant components in understanding and assessing financial performance. These measures should not be considered in isolation or as an alternative to net income, cash flows generated by operating, investing, or financing activities, earnings per share or other financial statement data presented in the consolidated financial statements as an indicator of financial performance or liquidity. Because these measures are not measurements determined in accordance with generally accepted accounting principles and are thus susceptible to varying calculations, these measures as presented may not be comparable to other similarly titled measures of other companies.

By filing this Current Report on Form 8-K, the Company does not acknowledge that disclosure of this information is required by Regulation FD or that the information was material or non-public before the disclosure. The Company assumes no obligation to update or supplement forward-looking statements in this presentation that become untrue because of new information, subsequent events or otherwise.

Item 9.01 Financial Statements and Exhibits.
