CSA INCOME FUND IV LIMITED PARTNERSHIP
NOTE TO FINANCIAL STATEMENTS

The quarterly financial statements have been prepared by the Partnership
without audit.  Certain information and footnote disclosures normally
included in the annual financial statements have been condensed or
omitted from the accompanying statements.  For such information, reference
should be made to the financial statements and notes thereto
included in the Partnership's annual report on Form 10-K for the year
ended December 31, 2001.

In the General Partner's opinion, the unaudited financial statements
reflect all adjustments which are of a normal recurring nature, necessary
to present fairly the financial position of CSA Income Fund IV Limited
Partnership as of June 30, 2002 and the results of operations and cash
flows for the three and six month periods ended June 30, 2002 and
June 30, 2001.

CSA INCOME FUND IV LIMITED PARTNERSHIP
GENERAL PARTNER'S DISCUSSION OF OPERATIONS

Rental income was $432,965 and $1,747,390 and net income was $387,862 and
$426,416 for the quarters ended June 30, 2002 and 2001, respectively.
For the six months ended June 30, 2002 and 2001, Rental income was
$1,088,045 and $3,878,892, and net income was $764,850 and $622,604.  The
decrease in net income for the quarter ended June 30, 2002 was primarily due
to lease expirations as the partnership approaches wind-up. The increase in
net income for the six months ended June 30, 2002 was primarily due
to lower depreciation expense recorded of $471,202 as compared to $2,963,127
for the same period in 2001. The depreciation expense is significantly lower
in 2002 primarily due to a majority of the remaining leases in the
Partnership's portfolio being nearly or fully depreciated.

The Partnership generated $782,502 in cash flow from operations and from the
sale of equipment during the three months ended June 30, 2002. The Partnership
utilized these funds and cash on hand to reduce outstanding notes payable by
$37,939 and made cash distributions to the partners of $1,535,685.

The Partnership paid distributions of $1.00 per Limited Partnership unit on
the April 15th, May 15th, and June 14th 2002.

To date, the Partnership has made cash distributions to the Limited Partners
ranging from 88% to 110% of their initial investment, depending on when the
Limited Partners entered the Partnership. The objective of the Partnership
is to return the Limited Partner's investment through current
distributions and provide a return on this investment by continued
distributions.

As noted previously, the General Partner of CSA Income Fund IV Limited
Partnership is in the process of completing the wind-up of the
Partnership. In finalizing the sale of the remaining Partnership
assets certain Partnership aircraft engines, are requiring additional
General Partner effort in order to maximize the value of these assets to
the Limited Partners. As soon as the remarketing of these Partnership assets
has been completed, the Partnership will make a Final Distribution to the
Limited Partners.

<page>
GENERAL PARTNER'S DISCUSSION OF OPERATIONS (continued)

In accordance with the Partnership Agreement, pursuant to section 8.3 (c),
accounting profits from the sale of equipment that are generated as
part of the Partnership's wind-up shall be allocated to each partner,
first in the amount equal to the negative balance in the capital account
of such partner; and secondly, 99% to the Limited Partners and 1% to
the General Partner. Therefore, certain gains on the disposition of
partnership assets were allocated during the first two quarters of 2002
and 2001 to the General Partner to reduce its Capital Account negative balance.

Management reviews the Partnership's projected performance on a periodic basis.
Based on that analysis the General Partner presently estimates that continued
cash distributions will return the entire initial investment of the Limited
Partners and a return thereon. The General Partner will continue to report
on the Limited Partners' return of investment with each cash distribution.
