Item 8.01.        Other Events.

                  Acadia  Realty  Trust (the  "Company")  is filing this Current
Report  on  Form  8-K  to  retrospectively   adjust  its  historical   financial
information  for each of the three years  included in its Annual  Report on Form
10-K for the fiscal  year  ended  December  31,  2005 (the  "Form  10-K").  This
retrospective  adjustment gives effect to the Company's  elective  retrospective
application  of the  provisions  of Emerging  Issues Task Force  ("EITF")  04-5,
"Determining  Whether a General  Partner,  or the  General  Partners as a Group,
Controls a Limited  Partnership or Similar Entity When the Limited Partners Have
Certain Rights".

                  Pursuant  to the  provisions  of EITF 04-5,  the  Company  has
determined that it should report its investments in Acadia Strategic Opportunity
Fund I, LP, Acadia  Strategic  Opportunity Fund II, LLC, Acadia Mervyn Investors
I, LLC and Acadia Mervyn  Investors II, LLC on a consolidated  basis rather than
under the  equity  method of  accounting,  as it had  previously  reported  such
entities.  The  Company's  election  to  retrospectively  adjust its  historical
financial  information is more fully described in the Notes to the  Consolidated
Financial  Statements  in Exhibit 99.1.  In  connection  with the  retrospective
adjustment of its historical financial information, the Company has reclassified
certain properties held for sale subsequent to December 31, 2005 as discontinued
operations,  as more fully described in Note 2 in the Notes to the  Consolidated
Financial Statements.

                  The  information  set forth in  Exhibit  99.1 to this  Current
Report  on Form 8-K  updates  Items 6, 7,  7A, 8 and  15(a) of the Form  10-K to
reflect the retrospective  application of EITF 04-5 and the  reclassification of
certain properties as discontinued  operations,  as described above. The updated
information  relates to Selected  Financial  Data,  Management's  Discussion and
Analysis of Financial  Condition  and Results of  Operations,  Quantitative  and
Qualitative Disclosures about Market Risk and Financial Statements for the years
presented  in the Form 10-K.  The Company is not required to amend its Form 10-K
but has voluntarily elected to provide this retrospectively  adjusted historical
financial information.

                  The Company has not updated  matters in the Form 10-K,  except
to the extent  expressly  provided  above.  The information set forth in Exhibit
99.1 to this Current  Report on Form 8-K does not reflect  events that  occurred
after the filing of the Form 10-K and does not  modify or update the  disclosure
in the Form 10-K other than to retrospectively  adjust its historical  financial
information  in  accordance  with EITF 04-5 and to reclassify  its  discontinued
operations.
