                     First Trust/FIDAC Mortgage Income Fund
                           July 31, 2008 (Unaudited)

                     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  determined  daily,  as of the close of
regular  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 NAV per  Common  Share  is
calculated  by dividing the value of all assets of the Fund  (including  accrued
interest and dividends),  less all liabilities  (including accrued expenses, the
dividends  declared  but unpaid and any  borrowings  of the Fund),  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  values
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  Fund's  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 are valued at
amortized cost. In the event that market  quotations are not readily  available,
the pricing service does not provide a valuation for a particular  asset, or the
valuations are deemed unreliable,  First Trust Advisors L.P. ("First Trust") may
use a fair value method to value the Fund's  securities  and other  investments.
Additionally,  if events  occur  after the close of the  principal  markets  for
particular securities (e.g.,  domestic debt and foreign securities),  but before
the Fund values its assets,  that could  materially  affect NAV, First Trust may
use a fair value method to value the Fund's  securities  and other  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.

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.

C. REVERSE REPURCHASE AGREEMENTS:

The Fund utilizes leverage through the use of reverse repurchase  agreements.  A
reverse  repurchase  agreement,  although  structured  as a sale and  repurchase
obligation,  acts as a  financing  under  which the Fund  pledges  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 nine months ended July 31, 2008 :

Maximum amount outstanding during the period...................   $26,448,000
Average amount outstanding during the period*..................   $23,416,493
Average monthly shares outstanding during the period...........     4,045,236
Average debt per share outstanding during the period...........   $      5.79

* 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-month period ended July 31, 2008.

Interest  rates  ranged from 1.98% to 4.94% during the  nine-month  period ended
July 31, 2008, on borrowings  by the Fund under reverse  repurchase  agreements,
which had interest expense that aggregated $553,162.

D. INVERSE FLOATING-RATE INSTRUMENTS:

An inverse  floating-rate  security is one where the coupon is inversely indexed
to a short-term  floating  interest rate multiplied by a specific factor. As the
floating  rate rises,  the coupon is reduced.  Conversely,  as the floating rate
declines,  the coupon is increased.  The price of these  securities  may be more
volatile than the price of a comparable  fixed-rate security.  These instruments
are typically used to enhance the yield of the portfolio.  The  investments  are
identified on the Portfolio of Investments.

                                                                          Page 5

          240.15d-15(b)).


     (b)  There  were no  changes  in the  registrant's  internal  control  over
          financial  reporting (as defined in Rule  30a-3(d)  under the 1940 Act
          (17 CFR  270.30a-3(d))  that  occurred  during the  registrant's  last
