ITEM 5.07. Submission of Matters to a Vote of Security Holders

As previously disclosed, on February 28, 2013, Century Properties Fund XIX, LP, a Delaware limited partnership (“CPF XIX”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with AIMCO Properties, L.P., a Delaware limited partnership (“AIMCO Properties”) and AIMCO CPF XIX Merger Sub LLC, a Delaware limited liability company of which AIMCO Properties is the sole member (the “Merger Subsidiary”). The Merger Agreement provides for (i) the merger of the Merger Subsidiary with and into CPF XIX, with CPF XIX as the surviving entity (the “Merger”), upon approval by a majority in interest of the units of limited partnership interest of CPF XIX (the “Units”) outstanding.

On June 18, 2013, AIMCO Properties and its affiliates took action by written consent to approve the Merger, which was completed on June 18, 2013. Prior to the Merger, there were 89,233 Units issued and outstanding, of which AIMCO Properties and its affiliates owned 60,711.66 Units (approximately 68.04%). After accounting for a voting restriction to which a portion of such Units were subject, AIMCO Properties and its affiliates were entitled to vote 49,469 Units, or approximately 55.44% of the outstanding Units, in favor of the Merger Agreement and the Merger. As a result of the Merger, each Unit outstanding immediately prior to consummation of the Merger (other than Units as to which appraisal rights are elected) was converted into the right to receive, at the election of the holder, either $364.65 in cash (the “Cash Consideration”) or 12.33 partnership common units of AIMCO Properties. Limited partners who reside in the State of California, or who fail to make an election, will receive only the Cash Consideration. In addition, as a result of the Merger, AIMCO Properties’ membership interest in the Merger Subsidiary was converted into 1,000 units of limited partnership interest of CPF XIX. Fox Partners II continues to be the general partner of CPF XIX and CPF XIX’s agreement of limited partnership in effect immediately prior to the Merger is the agreement of limited partnership of CPF XIX with the following change: a description of the merger was added.
