                           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 September 30, 2002 and the results of
operations and cash flows for the three and nine month periods ended
September 30, 2002 and September 30, 2001.

CSA INCOME FUND IV LIMITED PARTNERSHIP
FORM 10-Q
ITEM 2. - GENERAL PARTNER'S DISCUSSION OF OPERATIONS

Rental Income was $389,766 and $1,654,356 and Net Income was
$304,342 and $254,963 for the quarters ended September 30, 2002
and 2001, respectively.  For the nine months ended September 30, 2002
and 2001, Rental Income was $1,477,811 and $5,533,248, and Net Income
was $1,069,192 and $877,567, respectively. The decrease in Rental Income
was due to lease expirations as the partnership approaches wind-up. The
increase in Net Income was primarily due to decreases in  interest and
management fee expense on equipment leases that have expired, as well
as, decreased depreciation expense on leases that have been extended
or are paying on a month to month basis. The Partnership also recorded
a gain on foreign currency of $86,172 in the third quarter of 2002 as
compared to a loss of 3,832 in the prior year.

During the three months ended September 30, 2002, the Partnership
generated $414,478 in cash flow from operations and from the sale of
equipment. The Partnership utilized cash to reduce outstanding notes
payable by $38,592 and make cash distributions to the partners of $1,535,685.

The Partnership paid distributions of $1.00 per Limited Partnership unit on
July 15th, August 15th, and September 13th, 2002.

The General Partner will now complete the wind-up of the Partnership with a
final distribution on December 13th 2002. The December final distribution
will be approximately $9.00-$10.00 per unit.

The Limited Partners will receive their final Partnership K-1 package in
early March 2003.

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 three quarters of 2002
and 2001 to the General Partner to reduce its Capital Account negative
balance.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Not Applicable


Item 4. CONTROLS AND PROCEDURES

The General Partner has evaluated the Partnership's disclosure controls
and procedures. Based on that evaluation, it was determined that
the Partnership's disclosure controls and procedures are effective in
ensuring information required to be disclosed by the Partnership in its
Exchange Act Reports is accumulated and communicated to the
Partnership's management as appropriate to allow timely decisions
regarding required disclosure.

The General Partner has also evaluated the Partnership's internal
control structure. Based on that evaluation, it was determined that there
were no significant changes in the Partnership's internal controls or in
other factors that could affect these controls subsequent to the date
of the evaluation, including any corrective action with regard to
significant deficiencies and material weaknesses.
