The net asset value ("NAV") of the Common Shares of the First Trust
Tax-Advantaged Preferred 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,
dividends declared but unpaid and any borrowings of the Fund) and the
liquidation value of any outstanding Auction Preferred Shares, 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
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. RESTRICTED SECURITIES:

The Fund invests in restricted securities, which are securities that cannot be
offered for public sale without first being registered under the Securities Act
of 1933, as amended. Prior to registration, restricted securities may only be
resold in transactions exempt from registration. As of July 31, 2008, the Fund
held restricted securities as shown in the following table. The Fund does not
have the right to demand that such securities be registered. These securities
are valued according to the valuation procedures as stated in the Portfolio
Valuation footnote (Note 1A) and are not expressed as a discount to the carrying
value of comparable unrestricted securities.

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
            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
            fiscal  quarter that have  materially  affected,  or are  reasonably
            likely to materially affect, the registrant's  internal control over
            financial reporting.

ITEM 3. EXHIBITS.
