Introductory Note

This Amendment No. 37 (this “Amendment No. 37”) is filed with respect to the issuer, Angeles Partners XII, 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”), Cooper River Properties, L.L.C. (“Cooper River”) and Broad River Properties, L.L.C. (“Broad River” and, together with AIMCO Properties, AIMCO GP, AIMCO, AIMCO IPLP, AIMCO/IPT and Cooper River, the “Reporting Persons”). This Amendment No. 37 amends and supplements the statement on Schedule 13D, as amended and supplemented to date (the “Schedule 13D”), previously filed with the Securities and Exchange Commission with respect to the Partnership by the Reporting Persons or certain of their affiliates.

The Schedule 13D is amended to make the following changes to Items 4 and 5:

Item 4.

Purpose of Transaction

Item 4 is hereby supplemented by the addition of the following information:

On November 15, 2011, Angeles Partners XII, LP, a Delaware limited partnership (the “Partnership”) entered into an amended and restated agreement and plan of merger (the “Amended and Restated Merger Agreement”) with AIMCO Properties and AIMCO AP XII Merger Sub LLC, a Delaware limited liability company of which AIMCO Properties is the sole member (the “Merger Subsidiary”). The Amended and Restated Merger Agreement provides for the Merger Subsidiary to be merged with and into the Partnership, with the Partnership as the surviving entity, upon approval by a majority in interest of the units of limited partnership interest of the Partnership (the “AP XII Units”) outstanding.

On January 23, 2012, AIMCO Properties and its affiliates, which owned 33,750 of the 44,718 issued and outstanding AP XII Units, or approximately 75.47% of the number of units outstanding, took action by written consent to approve the merger, which was completed on January 23, 2012. In the merger, each AP XII Unit outstanding immediately prior to the merger (other than AP XII Units as to which appraisal rights are elected) was converted into the right to receive, at the election of the holder, either $483.14 in cash (the “Cash Consideration”), or 21.01 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 the merger, AIMCO Properties’ membership interest in the Merger Subsidiary was converted into 1,000 AP XII Units. Angeles Realty Corporation II continues to be the managing general partner of the Partnership, AIMCO Angeles GP, LLC continues to be the non-managing general partner of the Partnership and the Partnership’s agreement of limited partnership in effect immediately prior to the merger remains unchanged.

Item 5.

Interest in Securities of the Issuer

Item 5 is hereby amended and restated in its entirety as follows:

(a)-(b) The information in rows (7) through (11) and (13) of each Reporting Person’s cover page is incorporated herein by reference.

Item 7.
