                         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, 2000.

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 March 31, 2001 and the results of operations and cash flows for the
Three month periods ended March 31, 2001 and March 31, 2000.

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

Rental income was $2,131,502 and $2,812,258 and net income was $196,188
And $386,873 for the quarters ended March 31, 2001 and March 31, 2000,
respectively. The decrease in rental income was primarily due to lease
expirations as the partnership approaches wind-up. The decrease in net
income was primarily due to a decrease in gain on sale of equipment
recorded in the quarter ended March 31, 2001 of $64,949 as compared to $315,385
for the same period in 2000.

During the first quarter of 2001, the Partnership recorded a loss on foreign
currency of $68,306 due to the US Dollar's increased strength versus European
currencies. The loss was the result of two factors: first, the Partnership had
cash balances in English sterling of approximately 720,000 as of and recorded
on it's December 31, 2000 Balance Sheet, also secondly,  sales and rent
proceeds received during this first quarter ended March 31, 2001 were
approximately 730,000. These cash balances are marked to market for reporting
on U.S.Financial Statements and since the value of sterling was 1.4159 as of
March 31st, an appropriate adjustment was made for the US Dollar equivalent
on the Partnership Financial Statements as of this date.

The Partnership generated $2,563,171 in cash flow from operations and
From the sale of equipment during the three months ended March 31, 2001. The
Partnership utilized these funds to reduce outstanding notes payable by
$1,099,708 and made cash distributions to partners of $1,279,737.

During March 2001, the Partnership purchased an interest, as an interim lender,
secured by equipment and a short term monthly lease payment obligation of a
Fortune 100 Company. The Partnership's portion of the short-term loan
participation was $3,800,666 of which $3,500,000 was outstanding as of March 31,
2001. The Partnership earns interest at the rate of 7.75% per annum on the
monthly reducing balances over the life of the participation. The General
Partner, in it's own right, has participated in this loan in an approximate
amount of $3,586,000. It is expected that this loan will be paid off by a
permanent lender in 30-60 days.

The Partnership paid distributions of $.83 per limited partnership unit on the
15th of January, February and March 2001.

To date, the Partnership has made cash distributions to the Limited Partners
ranging from 74% to 96% 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.

During the fourth quarter of year 2000, the General Partner of CSA Income
Fund IV Limited Partnership determined that it was in the best interest of
the Partnership and the Limited Partners to begin the wind-up of the Partnership
in year 2001.  The wind-up is currently anticipated to be completed
during year 2002.

<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 until
the Capital Accounts of the Limited Partners are equal to the amount of cash
which would be required to be distributed to the Limited Partners in order to
achieve Payout. Therefore, certain gains on the disposition of partnership
assets were allocated during the first quarter of 2001 to the General Partner to
reduce its Capital Account negative balance. This accounting entry has no cash
impact on future Limited Partnership distributions.

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.
