2. (2) Fixed assets, other than donations, shall be reported on the balance sheet of the AHCF-1 at cost.
(b) Each facility shall complete and file with the department and/or its agent annual financial and statistical report forms supplied by the department and/or his agent. Each facility shall also file a copy of the audited financial statements for the facility, covering the same period as the annual report. Information contained in such filings shall be used by the department to establish rates of payment.
