On August 31, 1999 an amendment to Form S-11, which registered an additional 8,000,000 BACs for sale to the public became effective.

On July 24, 2002 an amendment to Form S- 11, which registered an additional 7,000,000 BAC's for sale to the public became effective. As of March 31, 2003, subscriptions had been received and accepted by the General Partner in Series 20, Series 21, Series 22, Series 23, Series 24, Series 25, Series 26, Series 27, Series 28, Series 29, Series 30, Series 31, Series 32, Series 33, Series 34, Series 35, Series 36, Series 37, Series 38, Series 39, Series 40, Series 41, Series 42, Series 43 and Series 44 for 75,662,578 BAC's representing capital contributions of $756,292,680.

The Offering, including information regarding the issuance of BACs in series, is described on pages 144 to 149 of the Prospectus, as supplemented, under the caption "The Offering", which is incorporated herein by reference.

Description of Business

The Assignor Limited Partner's sole purpose is to act as a conduit through which all of the economic and tax benefits of an investment in the Fund are passed along to the investor BAC Holders. The Assignor Limited Partner does not charge any fees for its services and has no income.

The Fund's principal business is to invest as a limited partner in other limited partnerships (the "Operating Partnerships") each of which will own or lease and will operate an Apartment Complex exclusively or partially for low- and moderate-income tenants. Each Operating Partnership in which the Fund will invest will own Apartment Complexes which are completed, newly-constructed, under construction or rehabilitation, or to-be constructed or rehabilitated, and which are expected to receive Government Assistance. Each Apartment Complex is expected to qualify for the low-income housing tax credit under Section 42 of the Code (the "Federal Housing Tax Credit"), thereby providing tax benefits over a period of ten to twelve years in the form of tax credits which investors may use to offset income, subject to certain strict limitations, from other sources. Certain Apartment Complexes may also qualify for the historic rehabilitation tax credit under Section 48 of the Code (the "Rehabilitation Tax Credit"). The Federal Housing Tax Credit and the Government Assistance programs are described on pages 64 to 88 of the Prospectus, as supplemented, under the captions "Tax Credit Programs" and "Government Assistance Programs," which is incorporated herein by reference. Section 236 (f) (ii) of the National Housing Act, as amended, in Section 101 of the Housing and Urban Development Act of 1965, as amended, each provide for the making by HUD of rent supplement payments to low income tenants in properties which receive other forms of federal assistance such as Tax Credits. The payments for each tenant, which are made directly to the owner of their property, generally are in such amounts as to enable the tenant to pay rent equal to 30% of the adjusted family income. Some of the Apartment Complexes in which the Partnership has invested are receiving such rent supplements from HUD. HUD has been in the process of converting rent supplement assistance to assistance paid not to the owner of the Apartment Complex, but direc tly to the individuals. At this time, the Partnership is unable to predict whether Congress will continue rent supplement programs payable directly to owners of the Apartment Complex.

As of March 31, 2003 the Fund had invested in 24 Operating Partnerships on behalf of Series 20, 14 Operating Partnership on behalf of Series 21, 29 Operating Partnerships on behalf of Series 22, 22 Operating Partnerships on behalf of Series 23, 24 Operating Partnerships on behalf of Series 24, 22 Operating Partnerships on behalf of Series 25, 45 Operating Partnerships on behalf of Series 26, 16 Operating Partnerships on behalf of Series 27, 26 Operating Partnerships on behalf of Series 28, 22 Operating Partnerships on behalf of Series 29, 20 Operating Partnerships on behalf of Series 30, 27 Operating Partnerships on behalf of Series 31, 17 Operating Partnerships on behalf of Series 32, 10 Operating Partnerships on behalf of Series 33, 14 Operating Partnerships on behalf of Series 34, 11 Operating Partnerships on behalf of Series 35, 11 Operating Partnerships on behalf of Series 36, 7 Operating Partnerships on behalf of Series 37, 10 Operating Partnerships on behalf of Series 38, 9 Operating Partnerships on b ehalf of Series 39, 16 Operating Partnerships on behalf of Series 40, 20 Operating Partnerships on behalf of Series 41, 17 Operating Partnerships on behalf of Series 42, 16 Operating Partnerships on behalf of Series 43 and 4 Operating Partnerships on behalf of Series 44. A description of these Operating Partnerships is set forth in Item 2 herein.

The business objectives of the Fund are to:
(1)	provide current tax benefits to Investors in the form of Federal Housing Tax Credits and in limited instances, a small amount of Rehabilitation Tax Credits, which an Investor may apply, subject to certain strict limitations, against the investor's federal income tax liability from active, portfolio and passive income;
(2)	preserve and protect the Fund's capital and provide capital appreciation and cash distributions through increases in value of the Fund's investments and, to the extent applicable, equity buildup through periodic payments on the mortgage indebtedness with respect to the Apartment Complexes.
(3)	provide tax benefits in the form of passive losses which an Investor may apply to offset his passive income (if any); and
(4)	provide cash distributions (except with respect to the Fund's investment in certain Non-Profit Operating Partnerships) from Capital Transaction proceeds. The Operating Partnerships intend to hold the Apartment Complexes for appreciation in value. The Operating Partnerships may sell the Apartment Complexes after a period of time if financial conditions in the future make such sales desirable and if such sales are permitted by government restrictions.

The business objectives and investment policies of the Fund are described more fully on pages 49 to 61 of the Prospectus, as supplemented, under the caption "Investment Objectives and Acquisition Policies," which is incorporated herein by reference.
