PART I

Item 1. Business.

   (a) General Development of Business

   American Income Partners V-D Limited Partnership (the "Partnership") was
organized as a limited partnership under the Massachusetts Uniform Limited
Partnership Act (the "Uniform Act") on May 21, 1990 for the purpose of acquiring
and leasing to third parties a diversified portfolio of capital equipment.
Partners' capital initially consisted of contributions of $1,000 from the
General Partner (AFG Leasing IV Incorporated) and $100 from the Initial Limited
Partner (AFG Assignor Corporation). On September 27, 1990, the Partnership
issued 480,227 units, representing assignments of limited partnership interests
(the "Units"), to 806 investors. Unitholders and Limited Partners (other than
the Initial Limited Partner) are collectively referred to as Recognized Owners.
The Partnership has one General Partner, AFG Leasing IV Incorporated, a
Massachusetts corporation and an affiliate of Equis Financial Group Limited
Partnership (formerly known as American Finance Group), a Massachusetts limited
partnership ("EFG"). The General Partner is not required to make any other
capital contributions except as may be required under the Uniform Act and
Section 6.1(b) of the Amended and Restated Agreement and Certificate of Limited
Partnership (the "Restated Agreement, as amended").

   (b) Financial Information About Industry Segments

   The Partnership is engaged in only one industry segment: the business of
acquiring capital equipment and leasing the equipment to creditworthy lessees on
a full payout or operating lease basis. (Full payout leases are those in which
aggregate undiscounted, noncancellable rents exceed the acquisition cost of the
leased equipment. Operating leases are those in which the aggregate
undiscounted, noncancellable rental payments are less than the acquisition cost
of the leased equipment.) Industry segment data is not applicable.

   (c)  Narrative Description of Business

   The Partnership was organized to acquire a diversified portfolio of capital
equipment subject to various full payout and operating leases and to lease the
equipment to third parties as income-producing investments. More specifically,
the Partnership's primary investment objectives were to acquire and lease
equipment that would:

   1. Generate quarterly cash distributions;

   2. Preserve and protect invested capital; and

   3. Maintain substantial residual value for ultimate sale.

   The Partnership has the additional objective of providing certain federal
income tax benefits.

   The Closing Date of the Offering of Units of the Partnership was September
27, 1990. The initial purchase of equipment and the associated lease commitments
occurred on September 28, 1990. The acquisition of the equipment and its
associated leases is described in Note 3 to the financial statements included in
Item 14, herein. The Restated Agreement, as amended, provides that the
Partnership will terminate no later than December 31, 2000. However, the
Partnership is a Nominal Defendant in a Class Action Lawsuit, the outcome of
which could significantly alter the nature of the Partnership's organization and
its future business operations. See Note 6 to the financial statements in the
1999 Annual Report.

   The Partnership has no employees; however, it is managed pursuant to a
Management Agreement with EFG or one of its affiliates (the "Manager"). The
Manager's role, among other things, is to (i) evaluate, select, negotiate, and
consummate the acquisition of equipment, (ii) manage the leasing, re-leasing,
financing, and refinancing of equipment, and (iii) arrange the resale of
equipment. The Manager is compensated for such services as provided for in the
Restated Agreement, as amended, described in Item 13 herein, and in Note 4 to
the financial statements included in Item 14, herein.


                                       3
<PAGE>

   The Partnership's investment in equipment is, and will continue to be,
subject to various risks, including physical deterioration, technological
obsolescence and defaults by lessees. A principal business risk of owning and
leasing equipment is the possibility that aggregate lease revenues and equipment
sale proceeds will be insufficient to provide an acceptable rate of return on
invested capital after payment of all debt service costs and operating expenses.
In addition, the leasing industry is very competitive. The Partnership is
subject to considerable competition when equipment is re-leased or sold at the
expiration of primary lease terms. The Partnership must compete with lease
programs offered directly by manufacturers and other equipment leasing
companies, including limited partnerships and trusts organized and managed
similarly to the Partnership, and including other EFG sponsored partnerships and
trusts, which may seek to re-lease or sell equipment within their own portfolios
to the same customers as the Partnership. Many competitors have greater
financial resources and more experience than the Partnership, the General
Partner and the Manager. In addition, default by a lessee under a lease may
cause equipment to be returned to the Partnership at a time when the General
Partner or the Manager is unable to arrange for the re-lease or sale of such
equipment. This could result in the loss of anticipated revenue.

   Revenue from individual lessees which accounted for 10% or more of lease
revenue during the years ended December 31, 1999, 1998 and 1997 is incorporated
herein by reference to Note 2 to the financial statements in the 1999 Annual
Report. Refer to Item 14(a)(3) for lease agreements filed with the Securities
and Exchange Commission.

   EFG is a Massachusetts limited partnership formerly known as American Finance
Group ("AFG"). AFG was established in 1988 as a Massachusetts general
partnership and succeeded American Finance Group, Inc., a Massachusetts
corporation organized in 1980. EFG and its subsidiaries (collectively, the
"Company") are engaged in various aspects of the equipment leasing business,
including EFG's role as Manager or Advisor to the Partnership and several other
direct-participation equipment leasing programs sponsored or co-sponsored by EFG
(the "Other Investment Programs"). The Company arranges to broker or originate
equipment leases, acts as remarketing agent and asset manager, and provides
leasing support services, such as billing, collecting, and asset tracking.

   The general partner of EFG, with a 1% controlling interest, is Equis
Corporation, a Massachusetts corporation owned and controlled entirely by Gary
D. Engle, its President, Chief Executive Officer and sole Director. Equis
Corporation also owns a controlling 1% general partner interest in EFG's 99%
limited partner, GDE Acquisition Limited Partnership ("GDE LP"). Mr. Engle
established Equis Corporation and GDE LP in December 1994 for the sole purpose
of acquiring the business of AFG.

   In January 1996, the Company sold certain assets of AFG relating primarily to
the business of originating new leases, and the name "American Finance Group,"
and its acronym, to a third party. AFG changed its name to Equis Financial Group
Limited Partnership after the sale was concluded. Pursuant to terms of the sale
agreements, EFG specifically reserved the rights to continue using the name
American Finance Group and its acronym in connection with the Partnership and
the Other Investment Programs and to continue managing all assets owned by the
Partnership and the Other Investment Programs.

PART II

Item 5. Market for the Partnership's Securities and Related Security Holder
Matters.

   (a) Market Information

   There is no public market for the resale of the Units and it is not
anticipated that a public market for resale of the Units will develop.

   (b) Approximate Number of Security Holders

   At December 31, 1999, there were 757 record holders of Units in the
Partnership.

   (c) Dividend History and Restrictions

   Historically, the amount of cash distributions to be paid to the Partners has
been determined on a quarterly basis. Each quarter's distribution may have
varied in amount and was made 95% to the Limited Partners and 5% to the General
Partner. Generally, cash distributions have been paid within 15 days after the
completion of each calendar quarter.

   The Partnership is a Nominal Defendant in a Class Action Lawsuit described in
Note 6 to the accompanying Annual Report. The proposed settlement to that
lawsuit, if effected, will materially change the future organizational structure
and business interests of the Partnership, as well as its cash distribution
policies. In addition, commencing with the first quarter of 2000, the General
Partner believes that it will be in the Partnership's best interests to suspend
the payment of quarterly cash distributions pending final resolution of the
Class Action Lawsuit. Accordingly, future cash distributions are not expected to
be paid until the Class Action Lawsuit is adjudicated.

   Distributions in 1999 and 1998 were as follows:

                                     -----------      -----------      -----------
             Total                   $   454,952      $    22,748      $   432,204
                                     ===========      ===========      ===========
</TABLE>

   Distributions payable were $56,869 at both December 31, 1999 and 1998.

   There are no formal restrictions under the Restated Agreement, as amended,
that materially limit the Partnership's ability to pay cash distributions,
except that the General Partner may suspend or limit cash distributions to
ensure that the Partnership maintains sufficient working capital reserves to
cover, among other things, operating costs and potential expenditures, such as
refurbishment costs to remarket equipment upon lease expiration. Liquidity is
especially important as the Partnership matures and sells equipment, because the
remaining equipment base consists of fewer revenue-producing assets that are
available to cover prospective cash disbursements. Insufficient liquidity could
inhibit the Partnership's ability to sustain its operations or maximize the
realization of proceeds from remarketing its remaining assets.

   Cash distributions consist of Distributable Cash From Operations and
Distributable Cash From Sales or Refinancings.

   "Distributable Cash From Operations" means the net cash provided by the
Partnership's normal operations after general expenses and current liabilities
of the Partnership are paid, reduced by any reserves for working


                                       6
<PAGE>

capital and contingent liabilities to be funded from such cash, to the extent
deemed reasonable by the General Partner, and increased by any portion of such
reserves deemed by the General Partner not to be required for Partnership
operations and reduced by all accrued and unpaid Equipment Management Fees and,
after Payout, further reduced by all accrued and unpaid Subordinated Remarketing
Fees. Distributable Cash From Operations does not include any Distributable Cash
From Sales or Refinancings.

   "Distributable Cash From Sales or Refinancings" means Cash From Sales or
Refinancings as reduced by (i)(a) amounts realized from any loss or destruction
of equipment which the General Partner determines shall be reinvested in similar
equipment for the remainder of the original lease term of the lost or destroyed
equipment, or in isolated instances, in other equipment, if the General Partner
determines that investment of such proceeds will significantly improve the
diversity of the Partnership's equipment portfolio, and subject in either case
to satisfaction of all existing indebtedness secured by such equipment to the
extent deemed necessary or appropriate by the General Partner, or (b) the
proceeds from the sale of an interest in equipment pursuant to any agreement
governing a joint venture which the General Partner determines will be invested
in additional equipment or interests in equipment and which ultimately are so
reinvested and (ii) any accrued and unpaid Equipment Management Fees and, after
Payout, any accrued and unpaid Subordinated Remarketing Fees.

   "Cash From Sales or Refinancings" means cash received by the Partnership from
sale or refinancing transactions, as reduced by (i)(a) all debts and liabilities
of the Partnership required to be paid as a result of sale or refinancing
transactions, whether or not then due and payable (including any liabilities on
an item of equipment sold which are not assumed by the buyer and any remarketing
fees required to be paid to persons not affiliated with the General Partner, but
not including any Subordinated Remarketing Fees whether or not then due and
payable) and (b) any reserves for working capital and contingent liabilities
funded from such cash to the extent deemed reasonable by the General Partner and
(ii) increased by any portion of such reserves deemed by the General Partner not
to be required for Partnership operations. In the event the Partnership accepts
a note in connection with any sale or refinancing transaction, all payments
subsequently received in cash by the Partnership with respect to such note shall
be included in Cash From Sales or Refinancings, regardless of the treatment of
such payments by the Partnership for tax or accounting purposes. If the
Partnership receives purchase money obligations in payment for equipment sold,
which are secured by liens on such equipment, the amount of such obligations
shall not be included in Cash From Sales or Refinancings until the obligations
are fully satisfied.

   "Payout" is defined as the first time when the aggregate amount of all
distributions to the Recognized Owners of Distributable Cash From Operations and
Distributable Cash From Sales or Refinancings equals the aggregate amount of the
Recognized Owners' original capital contributions plus a cumulative annual
return of 11% (compounded quarterly and calculated beginning with the last day
of the month of the Partnership's Closing Date) on their aggregate unreturned
capital contributions. For purposes of this definition, capital contributions
shall be deemed to have been returned only to the extent that distributions of
cash to the Recognized Owners exceed the amount required to satisfy the
cumulative annual return of 11% (compounded quarterly) on the Recognized Owners'
aggregate unreturned capital contributions, such calculation to be based on the
aggregate unreturned capital contributions outstanding on the first day of each
fiscal quarter.
