order to purchase the Securities for such clients. 

Item 5.   Interest In Securities Of The Issuer
          (a)  The aggregate number and percentage of Securities to
which this Schedule 13D relates is 1,282,300 shares, representing

Mario J. Gabelli                     0                0.00%


          Mr. Gabelli is deemed to have beneficial ownership of the
Securities beneficially owned by each of the foregoing persons and
GFI is deemed to have beneficial ownership of the securities owned
beneficially by each of the foregoing persons other than Mr.
Gabelli. 
          (b) Each of the Reporting Persons and Covered Persons has
the sole power to vote or direct the vote and sole power to dispose
or to direct the disposition of the Securities reported for it,
either for its own benefit or for the benefit of its investment
clients or its partners, as the case may be, except that GAMCO
Investors, Inc. does not have authority to vote 135,800 of the
reported shares and except that GFI has sole dispositive and voting
power with respect to the shares of the Issuer held by the The

Growth Fund, The Gabelli Convertible Securities Fund, The Gabelli
Value Fund Inc., The Gabelli Small Cap Growth Fund , The Gabelli
Equity Income Fund, ,The Gabelli ABC Fund, and/or The Gabelli

interest of all joint filers does not exceed 25% of their total
voting interest in the Issuer and in that event, the Proxy Voting
Committee of each Fund (other than The Gabelli Growth Fund) shall
respectively vote that Funds shares, and except that, at any time,
the Proxy Voting Committee of each such Fund may take and exercise
in its sole discretion the entire voting power with respect to the
shares held by such Fund under special circumstances such as
regulatory considerations, and except that Gabelli & Company shares
with the clients for whose accounts such Securities were purchased
the voting and dispositive power with respect to the any shares
that may be purchased for such accounts, and except that the power
of Mr. Gabelli and GFI is indirect with respect to Securities
beneficially owned directly by other Reporting Persons.
