                     FIRST TRUST/FIDAC MORTGAGE INCOME FUND
                            JULY 31, 2007 (UNAUDITED)

                      1. VALUATION AND INVESTMENT PRACTICES

A. PORTFOLIO VALUATION:

The net asset value ("NAV") of the Common Shares of First Trust/FIDAC Mortgage
Income Fund (the "Fund") The NAV 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 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.

B. SECURITIES TRANSACTIONS:

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on an 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 on such securities
is not accrued until settlement date. The Fund maintains liquid assets with a
current value at least equal to the amount of its when-issued or
delayed-delivery purchase commitments. At July 31, 2007, the Fund had no
when-issued or delayed-delivery 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 nine months ended July 31, 2007:

    Maximum amount outstanding during the period .............   $ 23,998,000
    Average amount outstanding during the period* ............   $ 21,511,670
    Average monthly shares outstanding during the period .....      4,045,236
    Average debt per share outstanding during the period .....   $       5.32

* The average amount outstanding during the nine months 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, 2007.

Interest rates ranged from 5.23% to 5.45% during the nine months ended July 31,
2007, on borrowings by the Fund under reverse repurchase agreements.

                      2. 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.

                    3. UNREALIZED APPRECIATION (DEPRECIATION)

As of July 31, 2007, the aggregate gross unrealized appreciation for all
securities in which there was an excess of value over tax cost was $2,453,014
and the aggregate gross unrealized depreciation for all securities in which
there was an excess of tax cost over value was $1,049,730.


                                                                          Page 5
