                     FIRST TRUST/FIDAC MORTGAGE INCOME FUND
                                 JULY 31, 2006



                      1. VALUATION AND INVESTMENT PRACTICES

A. PORTFOLIO VALUATION:

The net asset value ("NAV") of the Common Shares of the First Trust/FIDAC
Mortgage Income Fund (the "Fund") is computed based upon the value of the Fund's
portfolio securities and other assets less any accrued liabilities. The NAV is
determined as of the close of regular session trading on the New York Stock
Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day the NYSE is open
for trading. Domestic debt securities and foreign securities are priced using
data reflecting the earlier closing of the principal markets for those
securities. The Fund calculates NAV per Common Share by subtracting the Fund's
liabilities (including accrued expenses, dividends payable and all borrowings of
the Fund) from the Fund's Total Assets (the value of the securities and other
investments the Fund holds plus cash or other assets, including interest accrued
but not yet received) and dividing the result by the total number of Common
Shares outstanding.

The Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value according
to procedures adopted by the Fund's Board of Trustees. Securities for which
market quotations are readily available are valued at market value, which is
currently determined using the last reported sale price or, if no sales are
reported (as in the case of some securities traded over-the-counter), the last
reported bid price, except that certain U.S. government securities are valued at
the mean between the last reported bid and asked prices. The Fund will value
mortgage-backed securities and other debt securities not traded in an organized
market on the basis of valuations provided by dealers or by an independent
pricing service, approved by the Board of Trustees, which uses information with
respect to transactions in such securities, quotations from dealers, market
transactions for comparable securities, various relationships between securities
and yield to maturity in determining value. Debt securities having a remaining
maturity of less than sixty days when purchased and debt securities originally
purchased with maturities of sixty days or more but which currently have
maturities of less than sixty days are valued at cost adjusted for amortization
of premiums and accretion of discounts. In the event that market quotations are
not readily available, the pricing service does not provide a valuation for a
particular security, or the valuations are deemed unreliable, or if events
occurring after the close of the principal markets for particular securities
(e.g., domestic debt and foreign securities), but before the Fund values its
assets, would materially affect NAV, First Trust Advisors L.P. may use a fair
value method to value the Fund's securities and investments. The use of fair
value pricing by the Fund is governed by valuation procedures adopted by the
Fund's Board of Trustees, and in accordance with the provisions of the
Investment Company Act of 1940, as amended.

The Fund values exchange-traded options and other derivative contracts at the
closing price on the exchange on which they are principally traded, or if not
traded, or no closing price is available, at the mean between the last bid and
asked prices.

B. SECURITIES TRANSACTIONS:

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Securities purchased or sold on a when-issued or delayed-delivery basis may be
settled a month or more after the trade date; interest income is not accrued
until settlement date. The Fund instructs the custodian to segregate assets of
the Fund with a current value at least equal to the amount of its when-issued
purchase commitments.

C. REVERSE REPURCHASE AGREEMENTS:

A reverse repurchase agreement, although structured as a sale and repurchase
obligation, acts as a financing under which the Fund will effectively pledge its
assets as collateral to secure a short-term loan. Generally, the other party to
the agreement makes the loan in an amount equal to a percentage of the market
value of the pledged collateral. At the maturity of the reverse repurchase
agreement, the Fund will be required to repay the loan and correspondingly
receive back its collateral. While used as collateral, the assets continue to
pay principal and interest which are for the benefit of the Fund.

Information for the period October 31, 2005 through July 31, 2006:

    Maximum amount outstanding during the period ..............  $   25,804,000
    Average amount outstanding during the period* .............  $   20,302,216
    Average monthly shares outstanding during the period ......       4,045,236
    Average debt per share outstanding during the period ......  $         5.02

* The average amount outstanding during the period was calculated by adding the
borrowings at the end of each day and dividing the sum by the number of days in
the nine months ended July 31, 2006.

                                                                          Page 3

ITEM 2. CONTROLS AND PROCEDURES.

         (a) The  registrant's   principal  executive  and  principal  financial
             officers,  or persons performing similar functions,  have concluded
             that  the  registrant's  disclosure  controls  and  procedures  (as
             defined in Rule 30a-3(c) under the Investment  Company Act of 1940,
             as amended (the "1940 Act") (17 CFR  270.30a-3(c)))  are effective,
             as of a date  within 90 days of the filing  date of the report that
             includes the disclosure required by this paragraph,  based on their
             evaluation  of  these  controls  and  procedures  required  by Rule
             30a-3(b)  under  the  1940  Act (17  CFR  270.30a-3(b))  and  Rules
             13a-15(b) or 15d-15(b)  under the Securities  Exchange Act of 1934,
             as amended (17 CFR 240.13a-15(b) or 240.15d-15(b)).

         (b) There were no changes in the  registrant's  internal  control  over
