On May 2, 2014, we filed the Articles Supplementary (the “Articles Supplementary”) to our charter with the State Department of Assessments and Taxation of Maryland reclassifying and redesignating all 300,000 shares of 6 1/2% Series L Cumulative Redeemable Preferred Stock (the “Series L Preferred Stock”) to become shares of our Preferred Stock (the “Preferred Stock”). Such shares of Series L Preferred Stock were previously classified pursuant to the Articles Supplementary (the “Series L Articles Supplementary”) classifying, establishing and designating 2,300,000 shares of Preferred Stock as shares of the Series L Preferred Stock. On April 19, 2013, we redeemed all 2,000,000 shares of issued and outstanding Series L Preferred Stock, and, in accordance with the Series L Articles Supplementary, after such redemption, all 2,000,000 shares of previously issued and outstanding Series L Preferred Stock had the status of authorized but unissued Preferred Stock, without further designation as to series or class. As of May 2, 2014, no shares of Series L Preferred Stock were issued or outstanding. The Articles Supplementary reclassified and redesignated the remaining 300,000 shares of Series L Preferred Stock effective on May 2, 2014.

The foregoing summary of the Articles Supplementary is qualified in its entirety by reference to the text of the Articles Supplementary, which is attached as Exhibit 3.1 to this Form 8-K and is incorporated by reference into this Item 5.03.

At our Annual Meeting of Stockholders held on May 1, 2014, our stockholders approved by requisite vote the proposals listed below. The final results for the votes regarding each proposal are set forth below. The proposals are described in further detail in our Definitive Proxy Statement on Schedule 14A as filed with the Securities and Exchange Commission on March 14, 2014.
