Introductory Note

This Amendment No. 34 (this “Amendment”) is filed with respect to the issuer, Century Properties Fund XIX, LP, a Delaware limited partnership (the “Partnership”), by AIMCO Properties, L.P. (“AIMCO Properties”), AIMCO-GP, Inc. (“AIMCO-GP”), Apartment Investment and Management Company (“AIMCO”), AIMCO IPLP, L.P. (“AIMCO IPLP”), AIMCO/IPT, INC. (“AIMCO/IPT”) and IPLP Acquisitions I, L.L.C. (“IPLP Acquisition” and, together with AIMCO Properties, AIMCO-GP, AIMCO, AIMCO IPLP and AIMCO/IPT, the “Reporting Persons”).

Item 4. Purpose of Transaction

On February 28, 2013, Century Properties Fund XIX, LP, a Delaware limited partnership (the “Partnership”), entered into an agreement and plan of merger (the “Merger Agreement”) with 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”), pursuant to which the Merger Subsidiary will be merged with and into the Partnership, with the Partnership as the surviving entity.

In the merger, each unit of limited partnership interest (each, a “Unit”) of the Partnership outstanding immediately prior to the consummation of the merger (other than Units held by limited partners who perfect their appraisal rights pursuant to the Merger Agreement) will be converted into the right to receive either (i) $364.65 in cash or (ii) a number of partnership common units of AIMCO Properties calculated by dividing $364.65 by the average closing price of Apartment Investment and Management Company common stock, as reported on the New York Stock Exchange, over the ten consecutive trading days ending on the second trading day immediately prior to the effective time of the merger. In the merger, AIMCO Properties’ membership interest in the Merger Subsidiary will be converted into Units of the Partnership. As a result, after the merger, AIMCO Properties will be the sole limited partner of the Partnership and will own all outstanding Units.

Completion of the merger is subject to certain conditions, including approval by a majority in interest of the limited partners holding Units. As of February 27, 2013, there were issued and outstanding 89,233 Units, and AIMCO Properties and its affiliates owned 60,711.66 of those Units, or approximately 68.04% of the number of Units outstanding. Approximately 25,228.66 of the Units owned by an affiliate of AIMCO Properties are subject to a voting restriction, which requires the Units to be voted in proportion to the votes cast with respect to Units not subject to this voting restriction. AIMCO Properties and its affiliates have indicated that they will vote all of their Units that are not subject to this restriction, approximately 35,483 Units or approximately 39.76% of the outstanding Units, in favor of the Merger Agreement and the merger. As a result, affiliates of AIMCO Properties will vote a total of approximately 49,469 Limited Partnership Units, or approximately 55.44% of the outstanding Units in favor of the Merger Agreement and the merger. AIMCO Properties and its affiliates have indicated that they intend to take action by written consent to approve the merger.

The Merger Agreement may be terminated, and the merger may be abandoned, at any time prior to consummation of the merger by the Partnership, AIMCO Properties or the Merger Subsidiary for any reason, and there is no assurance that the merger will be consummated.
