NOTES TO PORTFOLIO OF INVESTMENTS - (UNAUDITED)
--------------------------------------------------------------------------------

                     FIRST TRUST/FIDAC MORTGAGE INCOME FUND
                                  JULY 31, 2005

                      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. The NAV is determined 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. 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
Managed 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 ("MBS") 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 sixty days or less when purchased and debt
securities originally purchased with maturities in excess of sixty days but
which currently have maturities of sixty days or less 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. ("First Trust") 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.

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. OPTION CONTRACTS:

COVERED CALL OPTIONS. The Fund may enter into hedging and strategic transactions
to seek to reduce interest rate risk arising from any use of financial leverage
by the Fund, to facilitate portfolio management and to mitigate risks, including
interest rate and credit risks.

Options the Fund writes (sells) will either be exercised, expire or be cancelled
pursuant  to a  closing  transaction.  If the price of the  underlying  security
exceeds the option's  exercise  price,  it is likely that the option holder will
exercise the option.  If an option written (sold) by the Fund is exercised,  the
Fund would be obligated to deliver the underlying  security to the option holder
upon payment of the exercise price. In this case, the option premium received by
the Fund will be added to the amount  realized on the sale of the  security  for
purposes of determining gain or loss. If the price of the underlying security is
less than the  option's  exercise  price,  the call option  will  likely  expire
without  being  exercised.  The option  premium  will be  treated as  short-term
capital gain on the  expiration  date of the option.  The Fund may also elect to
close out its position in an option prior to its  expiration  by  purchasing  an
option of the same option series as the option written (sold) by the Fund.

These options give the option holder the right, but not the obligation, to
purchase a security from the Fund at the strike price on or prior to the
option's expiration date. The ability to successfully implement the Fund's
investment strategy depends on the ability of Fixed Income Discount Advisory
Company ("FIDAC" or the "Sub-Advisor") to predict pertinent market movements,
which cannot be assured. Thus, the use of options may require the Fund to sell
portfolio securities at inopportune times or for prices other than current
market value, may limit the amount of appreciation the Fund can realize on an
investment, or may cause the Fund to hold a security that it might otherwise
sell. As the writer (seller) of a covered option, the Fund forgoes, during the
option's life, the opportunity to profit from increases in the market value of
the security covering the option above the sum of the premium and the strike
price of the option, but has retained the risk of loss should the price of the
underlying security decline. The writer (seller) of an option has no control
over the time when it may be required to fulfill its obligation as a writer
(seller) of the option. Once an option writer (seller) has received an exercise
notice, it cannot effect a closing purchase transaction in order to terminate
its obligation under the option and must deliver the underlying security at the
exercise price.

                                                                          Page 3

C. 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.

D. 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.

         Maximum amount outstanding during the period .........  $   19,710,000
         Average amount outstanding during the period .........  $    1,745,901
         Average Monthly shares outstanding during the period .         902,051
         Average Debt per share outstanding during the period .  $         1.94

                   2. UNREALIZED APPRECIATION/(DEPRECIATION):

As of July 31, 2005, the aggregate gross unrealized appreciation for all
securities in which there was an excess of value over tax cost was $1,015,816
and the aggregate gross unrealized depreciation for all securities in which
there was an excess of tax cost over value was $1,102,930.
