                             Integrated ARROs Fund I
                          Notes to Financial Statements

1.    GENERAL

      The accompanying unaudited financial statements, notes and discussions
      should be read in conjunction with the audited financial statements,
      related notes and discussions contained in the Form N-SAR Semi-Annual
      Report for the year ended December 31, 2004, which is herein incorporated
      by reference.

      The financial information contained herein is unaudited; however, in the
      opinion of management, all adjustments necessary for a fair presentation
      of such financial information have been included. All of the
      aforementioned adjustments are of a normal recurring nature and there have
      not been any non-recurring adjustments included in the results reported
      for the current period.

      Integrated ARROs Fund I (the "Fund") is a grantor trust created under the
      laws of the State of New York and registered under the Investment Company
      Act of 1940 as a closed-end, non-diversified management investment
      company.

2.    SIGNIFICANT ACCOUNTING POLICIES

      Security Valuation

      The Payment Obligations are valued at the lower of fair market value (as
      determined by the Board of Directors of the Sponsor) or Minimum
      Termination Amount (as defined in the Trust Indenture).

      Federal Income Taxes

      The Fund is classified as a grantor trust. As a consequence, the Fund is
      not subject to Federal Income Taxation.

      Cash and Cash Equivalents

      Cash and cash equivalents represents payment obligations received by the
      Fund and which were invested in U. S. Treasury bills with maturities of
      three months or less.

3.    THE SPONSOR

      IR Pass-through Corporation is the Sponsor of the Fund and was/is a wholly
      owned subsidiary of Integrated Resources, Inc. ("Integrated") and its
      post-bankruptcy successor, Presidio Capital Corp. ("Presidio"). Presidio
      is an indirect but wholly owned subsidiary of NorthStar Capital Investment
      Corp., the majority shareholder of Presidio.



      Subject to the rights of the unitholders under the Trust Indenture,
      Presidio is responsible for the administration of the Fund through its
      indirect ownership of all of the shares of the Sponsor. AP-PCC III, L.P.
      ("AP-PCC"), an unaffiliated third party, provides administrative services
      to Presidio, who in turn provides services to the Fund.

4.    COMMITMENTS AND CONTINGENCIES

      The original prospectus of the Fund contemplated the Sponsor bearing all
      costs of administering the Fund only through the period in which the Fund
      will be receiving primary term payments. However, upon the period when the
      Fund will be receiving renewal term payments, the Fund was to bear a
      portion of such costs equal to the percentage of the renewal term payments
      received by the Fund in such year to all of the payments received by the
      Fund in such year.

      Based on a present value estimate of legal, accounting, trustee fees, and
      printing and mailing costs, the Sponsor filed a claim in Integrated's
      bankruptcy in 1994 and received $450,000 (the "Settlement Fund") in
      settlement of such claim. It was projected at the time of the settlement
      that such amount would be sufficient to enable the Sponsor to meet its
      obligations to the Fund, and its similar obligations to ARROs Fund II,
      through approximately the year 2000. However, there was no assurance given
      at the time of the settlement that the Settlement Fund, together with
      interest earned, would in fact be sufficient to fund the Sponsor's
      obligations through the year 2000. As of June 30, 1998, the Settlement
      Fund had been fully depleted. As a result of the full depletion of the
      Settlement Fund during the first six months of 1998, the Fund has had to
      pay administrative expenses from current payment obligations received.
      Consequently, the Fund paid $37,837 in expenses from the proceeds of the
      January 2005 through June 2005 payment obligations received.

5.    DISTRIBUTION PAYABLE

      The Trustee declared a $231,581 ($83.57 per unit) distribution payable to
      unitholders of record as of June 30, 2005. Such distribution was paid on
      July 15, 2005.

6.    SUBSEQUENT EVENTS

      On August 11, 2005 the Fund's Trustee  received  $18,701,832  representing
      the  payoff  of  principal  and  accrued   interest  on  all  six  Payment
      Obligations.  The Trustee declared a  $19,029,265.89  ($6,867.29 per unit)
      distribution  payable to  unitholders  of record as of September 30, 2005.
      Such distribution was paid on October 17, 2005.
