                                    PART III

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, N-CSR,
or the transition report or portion thereof, could not be filed within the
prescribed period.

On May 5, 2005, the company filed on Form 8-K an announcement that it had
recently been advised by KPMG LLP, its registered independent public accounting
firm, that conflicting accounting literature exists regarding whether certain of
the company's refundable entrance fee obligations should be classified as
current liabilities.

The company believes that its historical practice regarding the classification
of these liabilities is in accordance with generally accepted accounting
principles. Nevertheless, the company is continuing to review the issue
internally and with KPMG LLP, and has sought clarification from the Securities
and Exchange Commission (SEC).

The company intends to file its Quarterly Report on Form 10-Q for the quarter
ended March 31, 2005 (the "Form 10-Q") as promptly as practicable. However, the
company is not able to determine the likely timing of a response from the SEC to
its request for clarification regarding the classification of its entrance fee
obligations. Consequently, the company is unable to file its Form 10-Q by the
prescribed due date without unreasonable effort or expense, and may be unable to
do so by May 16, 2005.

Statements contained in this Form 12b-25 and statements made by or on behalf of
American Retirement Corporation relating hereto may be deemed to constitute
forward-looking statements made pursuant to the safe harbor provisions of the
Private Securities Litigation Reform Act of 1995. These forward-looking
statements include all statements that are not historical statements of fact and
those regarding the intent, belief or expectations of the company or its
management, including, without limitation, all statements regarding the
company's expectations or beliefs regarding its accounting review and the timing
of the filing of the Form 10-Q. These forward-looking statements are subject to
completion of the company's review of its accounting practices, and may be
affected by certain risks and uncertainties, including without limitation the
following: (i) there can be no assurance that the outcome of the SEC's review of
the company's accounting practices regarding entrance fee liabilities will not
require changes in the company's accounting policies and practices, (ii) there
can be no assurances that additional issues will not arise during the company's
accounting review or that changes to the company's current accounting practices
will not be required as a result of that review, and (iii) the risk factors
described in the company's Annual Report on Form 10-K for the year ended
December 31, 2004 under the caption "Risk Factors" and in the company's other
filings with the SEC. In light of the significant uncertainties inherent in the
forward-looking statements included herein, the company's actual results could
differ materially from such forward-looking statements. The company does not
undertake any obligation to publicly release any revisions to any
forward-looking statements contained herein to reflect events and circumstances
occurring after the date hereof or to reflect the occurrence of unanticipated

                                     PART IV

Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of

registrant was required to file such report(s) been filed? If the answer is no,

(3)  Is it anticipated that any significant change in results of operations from
the corresponding period for the last fiscal year will be reflected by the
earnings statements to be included in the subject report or portion thereof?

                                                         [ ] Yes   [X] No

estimate of the results cannot be made.
