                 (each a "Trust" and collectively the "Trusts")

                               DATED JULY 3, 2013

     Notwithstanding anything to the contrary in the prospectuses or statements
of additional information for each of the Trusts, effective March 31, 2013, each
fund in each Trust (each a "Fund" or collectively the "Funds") modified its
existing securities lending policy, or in the absence of an existing policy
adopted a securities lending policy, as follows.

     Each Fund may lend securities representing up to 33-1/3% of the value of
its total assets to broker-dealers, banks and other institutions to generate
additional income. When a Fund loans its portfolio securities, it will receive,
at the inception of each loan, cash collateral equal to at least 102% (for
domestic securities) or 105% (for international securities) of the market value
of the loaned securities. Collateral will be marked-to-market daily.

     Under a Fund's securities lending agreement, the securities lending agent
will generally bear the risk that a borrower may default on its obligation to
return loaned securities. The Funds, however, will be responsible for the risks
associated with the investment of cash collateral. A Fund may lose money on its
investment of cash collateral or may fail to earn sufficient income on its
investment to meet its obligations to the borrower.

     As with other extensions of credit, there may be risks of delay in recovery
of the securities or even loss of rights in the collateral should the borrower
of the securities fail financially. However, the Funds will only enter into
domestic loan arrangements with broker-dealers, banks, or other institutions
which First Trust has determined are creditworthy under guidelines approved by
the Board of Trustees. The Funds will pay a portion of the income earned on the
lending transaction to the placing broker and may pay administrative and
custodial fees in connection with these loans.

     In these loan arrangements, the Funds will receive collateral in the form
of cash, U.S. government securities or other high-grade debt obligations equal
to at least 102% (for domestic securities) or 105% (for international
securities) of the market value of the securities loaned as determined at the
time of loan origination. This collateral must be valued daily by First Trust or
the applicable Fund's lending agent and, if the market value of the loaned
securities increases, the borrower must furnish additional collateral to the
lending Fund. During the time portfolio securities are on loan, the borrower
pays the lending Fund any dividends or interest paid on the securities. Loans
are subject to termination at any time by the lending Fund or the borrower.
While a Fund does not have the right to vote securities on loan, it would
terminate the loan and regain the right to vote if that were considered
important with respect to the investment. When a Fund lends portfolio securities
to a borrower, payments in lieu of dividends made by the borrower to the Fund
will not constitute "qualified dividends" taxable at the same rate as long-term
capital gains, even if the actual dividends would have constituted qualified
dividends had the Fund held the securities.
