Item 1. Security and Issuer
This Amendment No. 1 to Schedule 13D on M/A Com, Inc.
(the "Issuer") is being filed on behalf of the undersigned to amend
the Schedule 13D, as amended ( the "Schedule 13D") which was
originally filed on September 2, 1992. Unless otherwise indicated,
all capitalized terms used herein but not defined herein shall have
the same meaning as set forth in the Schedule 13D.
Item 4. Purpose of Transaction
Item 4 to Schedule 13D is amended, in pertinent part, as
follows:
Gabelli & Company, Inc. is advising its retail discre-
tionary brokerage customers that it will no longer transact
business for their accounts on a discretionary basis. Accordingly,
Gabelli & Company, Inc. will henceforth only enter orders for these
accounts which are directed and authorized by such customers.
Item 5. Interest In Securities Of The Issuer
(a) The aggregate number and percentage of Securities to
which this Schedule 13D relates is 1,146,124 shares, representing
4.41% of 25,955,609 shares and reflects the action described in
Item 4 of this Amendment and the expiration on September 30, 1993
of a warrant to purchase common stock of the Issuer issued to
Gabelli & Company, Inc. in 1990. This latter number of shares is
arrived at by adding the number of shares reported as being
outstanding in the Issuer's most recently filed Form 10-Q dated
August 5, 1994 (25,848,585 shares) to the number of shares which
would be receivable by the Reporting Persons if they were to
convert all of the Issuer's Convertible Debentures held by them
(107,024 shares). However, at current market prices it would be
uneconomic for any person to convert any of such Convertible
Debentures and that substantially all such Convertible Debentures
and not just those held by the Reporting Persons would be converted
if it became economic to do so. Accordingly the Reporting Persons
believe that the percentage of beneficial ownership attributable to
them under the rules of the SEC are artificially high and that a
more realistic percentage of their aggregate economic interest,
which does not take into account the conversion of such Convertible
Debentures, would be 4.02%.
The Reporting Persons beneficially own the Securities as
follows:
Shares of % of Shares of % of
Common Class of Common Stock, Class
Name Stock Common Converted Converted
GFI:
As Principal 0 0.00% 0 0.00%
As Agent 362,000 1.40% 398,688 1.53%
GAMCO
As Principal 0 0.00% 0 0.00%
As Agent 612,100 2.37% 682,436 2.63%
GPP 65,000 0.25% 65,000 0.25%
Mario J. Gabelli 0 0.00% 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, from time
to time, GAMCO Investors, Inc. does not have authority to vote 100%
of the shares, and except that GFI shares with the Board of
Directors of The Gabelli Asset Fund, The Gabelli Growth Fund, The
Gabelli Convertible Securities Fund, The Gabelli Value Fund Inc.,
The Gabelli Global Telecommunications Fund, The Gabelli Global
Interactive Couch Potatoe Fund, The Gabelli Global Convertible
Securities Fund, Gabelli Gold Fund, Inc., The Gabelli Equity Trust
Inc., The Gabelli Small Cap Growth Fund and/or The Gabelli Equity
Income Fund voting power with respect to the 398,689 shares held by
such funds, so long as the aggregate voting interest of all joint
filers does not exceed 25% of the issuer's total voting interest
and, in that event, the Proxy Voting Committee of each fund (other
than The Gabelli Growth Fund) shall respectively vote that funds
shares.
(c) Information with respect to all transactions in the
Securities which were effected during the past sixty days by each
of the Reporting Persons and Covered Persons is set forth on
Schedule II annexed hereto and incorporated herein by reference.
Signature
After reasonable inquiry and to the best of my knowledge and
belief, I certify that the information set forth in this statement
is true, complete and correct.
