ITEM 6.   Ownership of More than Five Percent on Behalf of Another Person

This Schedule 13G filing is jointly filed by The Charger Corporation, First
Trust Portfolios L.P. and First Trust Advisors L.P. pursuant to Rule
13d-1(k)(1). The Charger Corporation is the General Partner of both First Trust
Portfolios L.P. and First Trust Advisors L.P. First Trust Portfolios L.P. acts
as sponsor of certain unit investment trusts which hold shares of the issuer.
The total number of shares of the issuer held by these unit investment trusts
is set forth in Row (8) above with respect to First Trust Portfolios L.P. No
individual unit investment trust sponsored by First Trust Portfolios L.P. holds
more than 3% of any registered investment company issuer's shares. First Trust
Advisors L.P., an affiliate of First Trust Portfolios L.P., acts as portfolio
supervisor of the unit investment trusts sponsored by First Trust Portfolios
L.P., certain of which hold shares of the issuer. Neither First Trust Portfolios
L.P., First Trust Advisors L.P. nor The Charger Corporation have the power to
vote the shares of the issuer held by these unit investment trusts sponsored by
First Trust Portfolios L.P. These shares are voted by the trustee of such unit
investment trusts so as to insure that the shares are voted as closely as
possible in the same manner and in the same general proportion as are the shares
held by owners other than such unit investment trusts. The difference, if any,
between the aggregate amount of shares beneficially owned by each reporting
person, as set forth in Row (9) above, and the number of shares of the issuer
held by the unit investment trusts sponsored by First Trust Portfolios L.P.
represents shares of the issuer which are either held in other registered
investment companies, pooled investment vehicles and/or separately managed
accounts for which First Trust Advisors L.P. serves as investment advisor and/or
investment sub-advisor. Each of First Trust Portfolios L.P., First Trust
Advisors L.P. and The Charger Corporation disclaims beneficial ownership of the
shares of the issuer identified in this filing.
