3.      Partners' Capital

The Partnership  Agreement (the Agreement) stipulates different methods by which
revenue,  income  and  loss  from  operations  and  gain or loss on the  sale of
aircraft are to be allocated  to the general  partner and the limited  partners.
Such  allocations are made using income or loss  calculated  under GAAP for book
purposes, which varies from income or loss calculated for tax purposes.

Cash  available  for  distributions,  including  the  proceeds  from the sale of
aircraft,  is  distributed  10% to the  general  partner  and 90% to the limited
partners.

The different methods of allocating items of income, loss and cash available for
distribution  combined with the calculation of items of income and loss for book
and  tax  purposes  result  in  book  basis  capital   accounts  that  may  vary

                                       7


significantly  from tax basis capital  accounts.  The ultimate  liquidation  and
distribution  of remaining cash will be based on the tax basis capital  accounts
following liquidation, in accordance with the Agreement.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

At September 30, 1999,  Polaris Aircraft Income Fund III (the Partnership) owned
a portfolio of 10 used McDonnell  Douglas DC-9-30 aircraft leased to Trans World
Airlines, Inc. (TWA) out of its original portfolio of 38 aircraft.


Partnership Operations

The  Partnership  recorded  net  income  of  $1,501,422  or  $2.69  per  limited
partnership  unit, for the three months ended September 30, 1999, as compared to
net income of $1,510,588 or $2.72 per limited  partnership  unit,  for the three
months  ended  September  30,  1998.  The  Partnership  recorded  net  income of
$4,410,673  or $7.72 per limited  partnership  unit,  for the nine months  ended
September  30, 1999  compared to net income of  $4,087,678  or $6.93 per limited
partnership unit, for the nine months ended September 30, 1998.

The decrease in net income during the three months ended  September 30, 1999, as
compared to the same period in 1998,  is primarily the result of the sale of the
remaining  inventory of aircraft parts from the dissembled  aircraft to Soundair
in 1998.  Additionally,  decreased interest income in 1999,  partially offset by
decreased interest and operating expenses,  discussed below,  contributed to the
decrease in net income for the three months ended September 30, 1999.

The increase in net income  during the nine months ended  September  30, 1999 is
due  to  decreases  in  depreciation,  interest,  operating  and  administrative
expenses,  partially offset by decreases in interest and other income, and gains
on the sale of aircraft inventory in 1998.

The decrease in depreciation  expense during the nine months ended September 30,
1999 is the result of several  aircraft  having been fully  depreciated  down to
their estimated salvage values during 1998.

Interest expense  decreased during the three and nine months ended September 30,
1999,  as compared to the same period in 1998,  due to the  continuing  payments
being made on the TWA hushkit notes payable.

Operating  expenses  decreased  during the three and nine months ended September
30, 1999, as compared to the same period in 1998, due to legal expenses incurred
during 1998, related to the sale of aircraft to Triton.

Administration  and other  expenses  decreased  during the three and nine months
ended September 30, 1999, as compared to the same period in 1998,  primarily due
to a decrease in printing and postage costs  resulting  from several  additional
investor  mailings  required in 1998.  Also  contributing to this decrease was a
decrease in consulting fees.

Interest income  decreased  during the three and nine months ended September 30,
1999,  as compared to the same periods in 1998,  primarily  due to a decrease in
the cash reserves due to distributions over the same periods.

Payments totaling $230,577 were received, and recognized as other income, during
the nine  months  ended  September  30,  1998,  from the sale of parts from nine
disassembled aircraft. There were no such sales in 1999.

The  increase  in  the  deferred   income  balance  at  September  30,  1999  is
attributable  to  differences  between the  payments  due and the rental  income
earned on the TWA  leases for the 10  aircraft  currently  on lease to TWA.  For
income recognition purposes,  the Partnership  recognizes rental income over the
life of the lease in equal monthly amounts.  As a result, the difference between

                                       9


rental  income  earned and the rental  payments  due is  recognized  as deferred
income.  The rental payments due from TWA during the three and nine months ended
September 30, 1999 exceeded the rental income earned on the TWA leases,  causing
an increase in the deferred income balance.


Liquidity and Cash Distributions

Liquidity - The  Partnership  received all lease  payments from its sole lessee,
TWA,  except for the  September  1999  lease  payment.  On October 1, 1999,  the
Partnership  received  its  $850,000  rental  payment  from  TWA that was due on
September 27, 1999.  This amount was included in rent and other  receivables  on
the balance sheet at September 30, 1999.

Polaris Investment Management  Corporation,  the general partner, has determined
that cash  reserves  be  maintained  as a  prudent  measure  to ensure  that the
Partnership  has  available  funds in the event that the  aircraft  presently on
lease  to TWA  require  remarketing,  and  for  other  contingencies,  including
expenses of the Partnership.  The Partnership's  cash reserves will be monitored
and may be revised from time to time as further information becomes available in
the future.

Cash  Distributions - Cash  distributions  to limited  partners during the three
months ended  September  30, 1999 and 1998 were  $1,374,890 or $2.75 per limited
partnership  unit,  and  $1,449,884  or  $2.90  per  limited  partnership  unit,
respectively.  Cash  distributions  to limited  partners  during the nine months
ended  September  30,  1999 and 1998  were  $5,049,596  or  $10.10  per  limited
partnership  unit,  and  $17,698,584  or $35.40 per  limited  partnership  unit,
respectively.  The timing and amount of future  cash  distributions  are not yet
known and will depend on the Partnership's  future cash requirements  (including
expenses of the  Partnership),  the need to retain cash  reserves as  previously
discussed in the Liquidity section and the receipt of rental payments from TWA.


Impact of the Year 2000 Issue

The inability of business  processes to continue to function correctly after the
beginning of the Year 2000 could have serious  adverse  effects on companies and
entities throughout the world. As discussed in prior filings with the Securities
and Exchange  Commission,  the General  Partner has engaged GE Capital  Aviation
Services,   Inc.  ("GECAS")  to  provide  certain  management  services  to  the
Partnership.  Both the General Partner and GECAS are  wholly-owned  subsidiaries
(either direct or indirect) of General  Electric Capital  Corporation  ("GECC").
All of the Partnership's operational functions are handled either by the General
Partner  and  GECAS  or  by  third   parties  (as  discussed  in  the  following
paragraphs), and the Partnership has no information systems of its own.

As discussed in the Partnership's Annual Report on Form 10-K, GECC and GECAS are
applying a Six Sigma quality  approach to identify and mitigate Year 2000 issues
in their information systems, products and services, facilities and suppliers as
well as to  assess  the  extent to which  Year 2000  issues  will  affect  their
customers.  Each business has a Year 2000 leader who oversees a multi-functional
remediation  project team responsible for remediation and contingency  planning,
applying a Six Sigma  quality  approach in four phases:  (1)  define/measure  --
identify and  inventory  possible  sources of Year 2000  issues;  (2) analyze --
determine the nature and extent of Year 2000 issues and develop project plans to
address  those  issues;  (3)  improve --  execute  project  plans and  perform a
majority  of  the  testing;  and  (4)  control  --  complete  testing,  continue
monitoring readiness and complete necessary  contingency plans. As of the end of
June 1999, virtually all significant information systems, products and services,
facilities  and  suppliers  were in the  control  phase.  As a final step in the
control  phase,  GECC  has  developed,  tested  and  is  prepared  to  implement
contingency plans to minimize disruption of critical business processes.

As noted  elsewhere,  the Partnership has ten aircraft and spare parts inventory
remaining in its portfolio at this time. All of these remaining  aircraft are on

                                       10


lease with Trans World Airlines, Inc. ("TWA"). TWA has advised GECAS that it has
adopted  procedures  to identify  and  address  Year 2000 issues and that it has
developed a plan to implement required changes in its equipment,  operations and
systems. To the extent, however, that TWA suffers any material disruption of its
business and  operations  due to Year 2000  failure of equipment or  information
systems,  such  disruption  would likely have a material  adverse  effect on the
Partnership's operations and financial condition.

Aside  from  maintenance  and  other  matters  relating  to  the   Partnership's
aircraft-related  assets discussed above, the principal  third-party  vendors to
the  Partnership  are those  providing  the  Partnership  with  services such as
accounting,  auditing, banking and investor services. GECAS has applied the same
standards  in  determining  the  Year  2000  capabilities  of the  Partnership's
third-party  vendors,  as GECAS has applied with respect to its outside  vendors
pursuant to its internal Year 2000 program.

The  scope  of the  global  Year  2000  effort  encompasses  many  thousands  of
applications  and computer  programs,  products  and  services,  facilities  and
facilities-related equipment suppliers, and customers. The Partnership, like all
business   operations,   is  also  dependent  on  the  Year  2000  readiness  of
infrastructure   suppliers   in   areas   such   as   utility,   communications,
transportation  and other services.  In this  environment,  there will likely be
instances of failure that could cause disruptions in business  processes or that
could affect  customers'  ability to repay  amounts owed to the  Partnership  or
vendors' ability to provide services  without  interruption.  The likelihood and
effects of failures in infrastructure systems, over which the Partnership has no
control,  cannot  be  estimated.  However,  aside  from the  impact  of any such
possible failures or the possibility of a disruption of TWA's business caused by
Year 2000  failures,  the General  Partner does not believe that  occurrences of
Year  2000  failures  will  have a  material  adverse  effect  on the  financial
position, results of operations or liquidity of the Partnership.

To date, the Partnership has not incurred any Year 2000 expenditures nor does it
expect  to incur any  material  costs in the  future.  However,  the  activities
involved in the Year 2000 effort  necessarily  involve estimates and projections
of activities and resources that will be required in the future. These estimates
and projections could change as work progresses.
