ITEM 7.01 REGULATION FD DISCLOSURE.

     An  independent  valuation  consultant  has  been  retained  to  assist  in
determining  the fair value of certain  portfolio  securities of RMK High Income
Fund,  Inc. (the  "Fund").  Recent  instability  in the markets for fixed income
securities,  particularly  mortgage-backed and asset-backed securities, has made
it more difficult to obtain  realistic  values for some of the Fund's  portfolio
securities.  In the absence of reliable market quotations,  portfolio securities
are  valued  by the  Fund's  investment  adviser  at their  "fair  value"  under
procedures established and monitored by the Fund's Board of Directors. The "fair
value" of securities  may be difficult to determine  and thus  judgment  plays a
greater role in this valuation process. Fair valuation procedures have been used
to value a  substantial  portion  of the  assets of the Fund with input from the
valuation  consultant and these  valuations are reflected in the daily net asset
value of the Fund's shares.

     This  information is furnished  pursuant to Item 7.01 of Form 8-K and shall
not be deemed to be "filed"  for the  purposes  of Section 18 of the  Securities
Exchange Act of 1934 or otherwise  subject to the  liabilities  of that Section,
unless we specifically incorporate it by reference in a document filed under the
Securities  Act of 1933 or the  Securities  Exchange Act of 1934. By filing this
report on Form 8-K and furnishing this information,  the Fund makes no admission
as to the  materiality of any  information in this report that is required to be
disclosed solely by reason of Regulation FD.



                                   SIGNATURES

     Pursuant to the  requirements of the Securities Act of 1934, the Registrant
has duly  caused  this  report  to be signed  on its  behalf by the  undersigned
hereunto duly authorized.
