FIRST TRUST ADVISORS L.P. ANNOUNCES PORTFOLIO MANAGER CONFERENCE CALL FOR FIRST
TRUST SENIOR FLOATING RATE INCOME FUND II

WHEATON, IL -- (BUSINESS WIRE) -- August 4, 2015 -- First Trust Advisors L.P.
("FTA") announced today that its Leveraged Finance Investment Team, portfolio
manager for the First Trust Senior Floating Rate Income Fund II (NYSE: FCT) (the
"Fund"), intends to host a conference call on TUESDAY, AUGUST 18, 2015, AT 4:15

management team provide an update for the Fund.

--    Dial-in Number: (866) 865-6631; International (706) 679-1727; and Passcode
      # 78889469. Please call 10 to 15 minutes before the scheduled start of the
      teleconference.

The Fund is a diversified, closed-end fund that seeks to provide investors with
a high level of current income consistent with capital preservation. The Fund
pursues its objective by investing in a professionally managed portfolio of
interests in senior secured floating rate corporate loans ("Senior Loans"). The
Fund invests in below investment grade Senior Loans. This involves the risk that
borrowers may default on obligations, or that lenders may have difficulty
liquidating the collateral securing the loans, or difficulty enforcing their
rights under the terms of the Senior Loans. Senior loans are subject to credit
risk and the potential for non-payment of scheduled principal or interest
payments, which may result in a reduction of the Fund's net asset value ("NAV").
The Fund utilizes leverage. The use of leverage for investment purposes
increases both investment opportunity and investment risk. In the event of a
default on one or more loans or other interest-bearing instruments held by the
Fund, the use of leverage can magnify the effect of any losses.

First Trust Advisors L.P., the Fund's investment advisor, along with its
affiliate, First Trust Portfolios L.P., are privately-held companies which
provide a variety of investment services, including asset management and
financial advisory services, with collective assets under management or
supervision of approximately $118 billion as of June 30, 2015, through unit
investment trusts, exchange-traded funds, closed-end funds, mutual funds and
separate managed accounts.

If you have questions about the Fund that you would like answered on the call,
please email your questions to cefquestions@ftadvisors.com in advance of the
call and refer to FCT, by Friday, August 14, 2015, 6:00 P.M. Eastern Time.

Past performance is no assurance of future results. Investment return and
principal value of an investment in the Fund will fluctuate. Shares, when sold,
may be worth more or less than their original cost.

Principal Risk Factors: The Fund is subject to various risks, including: Credit
Risk, Senior Loan Risk, Lower Grade Debt Instruments Risk, Interest Rate Risk,
Discount From or Premium to Net Asset Value Risk, Leverage Risk, , Limited
Secondary Market for Senior Loans, Unsecured Loans and Subordinated Loans,
Illiquid Securities, Non-U.S. Securities, Management Risk, Strategic
Transactions, Reinvestment Risk, Prepayment Risk, Inflation Risk, Regulatory
Changes, Market Event risk, anti-Takeover Provisions.

The Senior Loans in which the Fund invests are generally rated below investment
grade by one or more rating agencies and are considered to be "high-yield"
securities. High-yield securities should be considered speculative as their low
ratings indicate a quality of less than investment grade, and therefore carry an
increased risk of default as compared to investment grade issues. Because
high-yield securities are generally subordinated obligations and are perceived
by investors to be riskier than higher rated securities, their prices tend to
fluctuate more than higher rated securities and are affected by short-term
credit developments to a greater degree. High-yield securities are subject to
greater market fluctuations and risk of loss than securities with higher
investment ratings. A reduction in an issuer's creditworthiness may result in
the bankruptcy of an issuer or the default by an issuer on the interest and
principal payments. The market for high-yield securities is smaller and less
liquid than that for investment grade securities.

The risks of investing in the Fund are spelled out in the prospectus,
shareholder reports, and other regulatory filings.

The Fund's daily New York Stock Exchange closing price and daily net asset
value, as well as other information are available at www.ftportfolios.com or by
