Competition

The Company  competes in the  semiconductor  industry,  servicing  and providing
solutions for a variety of high-speed  communication and computer  applications.
Many of the Company's larger customers conduct business in the personal computer
and  related  peripheral  devices   industries.   Intense   competition,   rapid
technological  change,  cyclical market  patterns,  price erosion and periods of
mismatched supply and demand have historically characterized these industries.

The Company faces  competition from several large  semiconductor  manufacturers,
some of which have greater size and financial  resources  than the Company.  The
Company's  principal  competitors in the advanced I/O controller  market include
National  Semiconductor   Corporation,   Winbond  Electronics   Corporation  and
Integrated Technology Express, Inc. (ITE).

As SMSC  continues  to broaden  its product  offerings,  it will likely face new
competitors in other markets.  Many of the Company's potential  competitors have
the ability to invest larger dollar amounts into research and  development,  and
some  have  their  own  manufacturing  facilities,  which  may give  them a cost
advantage on large volume products.

The principal  methods that the Company uses to compete include the introduction
of  innovative  new products,  providing  industry-leading  product  quality and
customer  service,  adding  new  features  to its  products,  improving  product
performance,   striving  to  ensure   availability   of  product  and   reducing
manufacturing costs. SMSC also cultivates  strategic  relationships with certain
key customers who are technology  leaders in its target  markets,  which provide
insight into market trends and  opportunities  for the Company to better support
those customers' needs.

The  Company  believes  that it  currently  competes  effectively  in the  areas
discussed in the  previous  paragraph to the extent they are within its control.
However,  given the pace at which change occurs in the  semiconductor,  personal
computer  and  other  high-technology  industries,  SMSC's  current  competitive
capabilities are not a guarantee of future success.


Research and Development

The  semiconductor  industry,  and the  individual  markets in which the Company
currently  competes,  are highly  competitive,  and the  Company  believes  that
continued   investment  in  research  and  development  (R&D)  is  essential  to
maintaining  and  improving  its  competitive   position.   SMSC  has  strategic
relationships  with many of its  customers  and tailors its  solutions  to these
specific  customers'  needs.  Serving  a wide  array of world  class  OEMs,  the
Company's continued success will be based, among other things, on its ability to
meet the  individual  needs of these  customers and to help them speed their own
products to market.

SMSC's R&D  activities are performed by a team of  highly-skilled  engineers and
technicians,  and are primarily  directed  towards the design of new  integrated
circuits in both  mainstream and emerging  technologies,  the development of new
software  design tools and blocks of logic,  as well as ongoing cost  reductions
and performance improvements in existing products.

In recent  years,  SMSC has migrated  from an  organization  with a  traditional
strength and rich  history in digital  design,  to become a supplier  with broad
engineering and design expertise in digital,  analog and mixed-signal solutions.
Electronic signals fall into one of two categories - analog or digital.  Digital
signals are used to represent the "ones" and "zeros" of binary  arithmetic,  and
are either on or off. Analog, or linear, signals represent real-world phenomena,
such as temperature,  pressure,  sound,  speed and motion.  These signals can be
detected and measured using analog sensors, which represent real-world phenomena
by generating  varying  voltages and  currents.  Mixed-signal  products  combine
digital and analog  circuitry into a single device.  Mixed-signal  solutions can
significantly  reduce package sizes by integrating system  interfaces,  reducing
external  component  requirements and lowering power  consumption,  all of which
reduce  system  costs.  Nearly half of SMSC's  currently  shipping  products are
mixed-signal devices.

SMSC employs engineers with a wide range of experience in digital,  mixed-signal
and analog MOS/VLSI circuit design,  from experienced  industry  veterans to new
engineers  recently  graduated  from  top  universities.  Their  activities  are
supported by state-of-the-art hardware, software, and other product design tools
procured from world-class  suppliers.  The Company's  engineering design centers
are strategically  located in New York, Texas and Arizona to take full advantage
of the  technological  expertise  found in each area,  and to closely cater to a
widespread base of customers located across the country.


Manufacturing

SMSC provides semiconductor solutions using a fabless manufacturing model, which
is  increasingly  common in the  semiconductor  industry.  Third party  contract
foundries and package assemblers are engaged to fabricate the Company's products
onto  silicon  wafers,  cut  these  wafers  into die and  assemble  the die into
finished  packages.  This strategy  allows the Company to focus its resources on
product design and development, marketing and quality assurance. It also reduces
fixed costs and capital  requirements,  and provides  the Company  access to the
most advanced manufacturing capabilities.

The Company's primary wafer suppliers are Chartered Semiconductor Manufacturing,
Ltd. in Singapore and Taiwan Semiconductor Manufacturing Company, Ltd. (TSMC) in
Taiwan.  The Company may  negotiate  additional  foundry  supply  contracts  and
establish  other  sources of wafer supply for its products as such  arrangements
become useful or necessary, either economically or technologically.

Processed silicon wafers are shipped to various third party assembly  suppliers,
most of which are located in the Pacific  Rim region,  where they are  separated
into individual chips that are then encapsulated  into plastic  packages.  As is
the case with the Company's wafer supply requirements,  SMSC employs a number of
independent  suppliers for assembly  purposes.  This enables the Company to take
advantage  of  the  subcontractor's  high  volume  manufacturing,  related  cost
savings, speed and supply flexibility.  It also provides SMSC with timely access
to  cost-effective  advanced  process  and  package  technologies.  The  Company
purchases most of its assembly services from Advanced Semiconductor Engineering,
Inc., ST Assembly Test Services, Ltd., Orient Semiconductor  Electronics,  Ltd.,
and Amkor Technology, Inc.

Following assembly,  each of the packaged units receives final testing,  marking
and  inspection  prior to shipment to  customers.  Final testing for most of the
Company's products is performed at SMSC's own state-of-the-art testing operation
in Hauppauge, New York. Final testing services of independent test suppliers are
also utilized as necessary, most of which occur in the Pacific Rim region.

Customers  demand  semiconductors  of the highest  quality and  reliability  for
incorporation into their products.  SMSC focuses on product reliability from the
initial  stages of the  design  cycle  through  each  specific  design  process,
including  production test design. In addition,  designs are subject to in-depth
circuit  simulation  at  temperature,  voltage and  processing  extremes  before
initiating  the  manufacturing  process.  The Company  prequalifies  each of its
assembly and foundry subcontractors. This prequalification process consists of a
series of industry  standard  environmental  product stress tests, as well as an
audit and  analysis  of the  subcontractor's  quality  system and  manufacturing
capability. Wafer foundry production and assembly services are closely monitored
to ensure consistent overall quality, reliability and yield levels.


New Brand Identity

On April 26, 2004,  SMSC unveiled a new global brand  identity,  including a new
logo,  a new  tagline - "Success by  Design,"  and a new  website  design at its
www.smsc.com homepage.  Through its communications  initiatives,  the Company is
placing  a new  emphasis  and focus on  building  awareness  of its  significant
accomplishments and unique capabilities to serve customers.  The new "Success by
Design"  tagline  underscores  the  Company's  mission  of  being  an  essential
ingredient that fuels its customers' success and highlights its culture which is
deliberate  in the  manner  in  which  it  ensures  success  for its  customers,
investors, suppliers, employees and other partners.


Sales, Marketing and Customer Service

SMSC has historically been a successful supplier of Application-Specific  Custom
Products  (ASCPs),  tailored to the specific needs of its customers.  To address
its customers'  aggressive cost and  time-to-market  objectives,  the Company is
increasingly  designing and delivering  Application-Specific  Standard  Products
(ASSPs),  while  remaining  focused on  retaining  its  expertise  of  providing
innovative, yet diverse, product features for its customers.

The  Company's  sales and  marketing  strategy  is to achieve  design  wins with
technology   leaders  in  targeted   markets  through   superior  sales,   field
applications  and engineering  support.  Sales managers are dedicated to key OEM
customers to ensure the highest  level of customer  service and to promote close
cooperation and communication.  The success of its customers is a cornerstone of
SMSC's corporate strategy.

The  Company  also  serves  its  customers  with a  worldwide  network  of field
application  engineers.  These engineers  assist  customers in the selection and
proper use of its products and are  available to answer  customer  questions and
resolve  technical  issues.  The field  application  engineers  are supported by
factory  application  engineers,  who  work  with  both the  customer's  and the
Company's  factory design and product engineers to develop the requisite support
tools and facilitate the smooth introduction of new products.

The Company  strives to make the  design-in  of its products as easy as possible
for its  customers.  To facilitate  this,  SMSC offers a wide variety of support
tools,  including evaluation boards, sample BIOS,  diagnostics programs,  sample
schematics and PCB layout files, driver programs, data sheets, industry standard
specifications and other  documentation.  These tools are readily available from
the Company's sales offices and sales  representatives.  SMSC's home page on the
World Wide Web  (www.smsc.com)  provides  customers with immediate access to its
latest product  information.  In addition,  the Company  maintains an electronic
bulletin board so that  registered  customers can download  software  updates as
needed.  Customers are also provided with reference platform designs for many of
the  Company's  products,  which enable easier and faster  transitions  from the
initial prototype designs through final production releases.

SMSC markets and sells its products in the United States  through a direct sales
force,   electronics  distributors  and  manufacturers'   representatives.   Two
independent  distributors  are  currently  engaged to serve the  majority of the
North American market.  Internationally,  products are marketed and sold through
regional sales offices  located in Germany,  Taiwan,  China and Korea as well as
through a network of independent  distributors and representatives.  The Company
serves  the  Japanese  marketplace  primarily  through  its  Tokyo,  Japan-based
subsidiary, SMSC Japan.

In accordance with industry practices,  most distributors have certain rights of
return and price protection  privileges on unsold products until the distributor
sells the product.  Distributor contracts may be terminated by written notice by
either  party.  The contracts  specify the terms for the return of  inventories.
Returns of product  pursuant to  termination of these  agreements  have not been
material.  Shipments made by SMSC Japan to  distributors in Japan are made under
agreements  that permit  limited or no stock return  privileges and generally no
price protection or other sales price rebates.

The  Company  generates a  significant  portion of its sales and  revenues  from
international  customers.  While  the  demand  for  the  Company's  products  is
primarily  driven by the  worldwide  demand for personal  computers,  peripheral
devices,  and embedded  systems  applications  sold by U.S.-based  suppliers,  a
significant  portion  of  the  Company's  products  are  sold  to  manufacturing
subcontractors of those U.S.-based  suppliers,  and to distributors who serve to
feed the high technology manufacturing pipeline, located in Asia and the Pacific
Rim.  The  majority  of  the  world's  personal   computer,   personal  computer
motherboard  and other high  technology  manufacturing  activity  occurs in that
region. The Company expects that international  shipments,  particularly to Asia
and the Pacific Rim regions, will continue to represent a significant portion of
its sales and revenues.

Intellectual Property

The Company  believes that  intellectual  property is a valuable  asset that has
been, and will continue to be, important to the Company's  success.  The Company
has received  numerous United States patents  relating to its  technologies  and
additional  patent  applications  are  pending.  It is the  Company's  policy to
protect these assets  through  reasonable  means.  To protect these assets,  the
Company relies upon nondisclosure agreements, contractual provisions, and patent
and copyright laws.

SMSC has patent  cross-licensing  agreements  with more than  thirty  companies,
including such semiconductor manufacturers as IBM, Intel, Micron Technology, NEC
and Toshiba,  providing access to more than 40,000 U.S.  patents.  Almost all of
the  Company's   cross-licensing   agreements   give  SMSC  the  right  to  use,
royalty-free,   patented  intellectual  property  of  the  other  companies.  In
situations where the Company needs to acquire  strategic  intellectual  property
not covered by cross-licenses, the Company enters into agreements to purchase or
license the required intellectual property.


Backlog and Customers

The  Company's  business,  and to a  large  extent  much  of  the  semiconductor
industry,  is characterized by short-term order and shipment  schedules,  rather
than volume purchase  contracts.  The Company schedules  production based upon a
forecast  of demand  for its  products.  Sales are made  primarily  pursuant  to
purchase orders  generally  requiring  delivery within one month,  and at times,
several  months.  Typical of industry  practice,  the  Company's  backlog may be
canceled or  rescheduled  by the  customer on short notice  without  significant
penalty.  As a result,  the  Company's  backlog may not be  indicative of actual
sales and therefore should not be used as a measure of future revenue.

From time to time,  several key customers can account for a significant  portion
of the  Company's  sales and  revenues.  Sales  and  revenues  from  significant
customers for fiscal 2004,  2003 and 2002,  stated as percentages of total sales
and revenues, are summarized as follows:


For the years ended February 29 or 28,     2004        2003        2002
- --------------------------------------------------------------------------
Customer A                                 16%         20%         15%
Customer B                                 16%         14%          6%
Customer C                                 12%         10%         29%
Customer D                                 12%         12%          6%

The  Company  expects  that its key  customers  will  continue  to account for a
significant  portion  of its  sales  and  revenues  in  fiscal  2005 and for the
foreseeable future.


Employees

At February 29, 2004,  the Company  employed 546  individuals,  including 122 in
sales,  marketing and customer  support,  130 in manufacturing and manufacturing
support,  199 in  research  and  product  development  and 95 in  administrative
support and building maintenance activities.

The Company's  future success depends in large part on the continued  service of
key technical and management personnel and on its ability to continue to attract
and retain  qualified  employees,  particularly  those  highly  skilled  design,
product and test engineers  involved in manufacturing  existing products and the
development of new products. The competition for such personnel is intense.

The Company has never had a work  stoppage.  No employees are  represented  by a
labor organization and the Company considers its employee relations to be good.

Other Factors That May Affect Future Operating Results

Before  deciding to invest in the  Company,  or to  maintain  or  increase  your
investment, you should carefully consider the risks described below, in addition
to the other  information  contained in this report and in the  Company's  other
reports filed or furnished  with the SEC,  including  the  Company's  reports on
Forms 10-Q and 8-K. The risks and uncertainties described below are not the only
ones facing the Company.  Additional risks and uncertainties not presently known
or  that  are  currently  deemed   immaterial  may  also  affect  the  Company's
operations. Any of the risks,  uncertainties,  events or circumstances described
below could cause the Company's  financial condition or results of operations to
be adversely affected.

The Semiconductor Industry - The Company competes in the semiconductor industry,
which  has  historically  been  characterized  by  intense  competition,   rapid
technological  change,  cyclical market  patterns,  price erosion and periods of
mismatched  supply  and  demand.  The  semiconductor  industry  has  experienced
significant  economic  downturns at various times in the past,  characterized by
diminished  product  demand  and  accelerated  erosion  of  selling  prices.  In
addition,  many of the Company's  competitors in the semiconductor  industry are
larger and have  significantly  greater  financial and other  resources than the
Company.

The Personal Computer Industry - Sales of many of the Company's  products depend
largely on sales of personal computers and peripheral devices. Reductions in the
rate of growth of the PC market could adversely  affect the Company's  operating
results. In addition,  as a component supplier to PC manufacturers,  the Company
may  experience  greater  demand  fluctuation  than  its  customers   themselves
experience.  Also,  some  of the  Company's  products  are  used  in PCs for the
consumer  market,  which can be more  volatile  than  other  segments  of the PC
marketplace.

The PC industry is  characterized  by ongoing product changes and  improvements,
much of which is driven by several large companies whose own business strategies
play  significant  roles in  determining PC  architectures.  Future shifts in PC
architectures  may not always be anticipated or be consistent with the Company's
product roadmaps.

Worldwide  Economic  Environment - Calendar 2001 and 2002 were  characterized by
slower economic  activity,  decreased  consumer  confidence,  reduced  corporate
profits  and  capital  spending  and  liquidity   concerns  which,   along  with
international  conflicts  and  terrorist  and military  activity,  resulted in a
downturn in  worldwide  economic  conditions.  As a result of these  unfavorable
economic  conditions,  the Company  experienced a slowdown in customer orders in
fiscal  2002.  The  Company's  fiscal 2003 and fiscal  2004 order  input  showed
sequential  improvement,  driven  by new  design  wins  and an  overall  general
economic recovery.  In addition,  recent political and social turmoil related to
international  conflicts  and  terrorist  acts may  place  further  pressure  on
economic conditions in the U.S. and worldwide. These unstable political,  social
and economic  conditions make it challenging for the Company,  its customers and
its suppliers to forecast and plan future business activities.

Product  Development  and  Technological  Change - The  Company's  prospects are
highly dependent upon the successful  development and timely introduction of new
products at competitive prices and performance  levels, with acceptable margins.
The  success  of new  products  depends  on various  factors,  including  timely
completion of product development  programs,  market acceptance of the Company's
and its customers' new products, securing sufficient foundry capacity for volume
manufacturing of wafers,  achieving  acceptable wafer fabrication  yields by the
Company's  independent  foundries and the  Company's  ability to offer these new
products  at  competitive  prices.  In order to succeed in having the  Company's
products  incorporated  into new products being  designed by its customers,  the
Company  must  anticipate  market  trends  and  meet  performance,  quality  and
functionality  requirements of such customers and must successfully  develop and
manufacture products that adhere to these requirements. In addition, the Company
must meet the timing and price  requirements of its customers and must make such
products available in sufficient quantities.  There can be no assurance that the
Company  will be able to identify  market  trends or new product  opportunities,
develop and market new products,  achieve design wins or respond  effectively to
new technological changes or product announcements by others.

The Company's future growth will depend, among other things, upon its ability to
continue to expand its product lines. To the extent that the Company attempts to
compete  in new  markets,  it may face  competition  from  suppliers  that  have
well-established  market positions and products that have already been proven to
be technologically and economically competitive.  There can be no assurance that
the Company will be  successful in  displacing  these  suppliers in the targeted
applications.

Price  Erosion  -  The  semiconductor   industry  is  characterized  by  intense
competition.  Historically, average selling prices in the semiconductor industry
generally,  and  for  the  Company's  products  in  particular,   have  declined
significantly over the life of each product. While the Company expects to reduce
the  average   selling   prices  of  its  products  over  time  as  it  achieves
manufacturing  cost reductions,  competitive and other pressures may require the
reduction  of selling  prices  more  quickly  than such cost  reductions  can be
achieved.  If not offset by reductions in  manufacturing  costs or by a shift in
the mix of products sold toward higher-margin products,  declines in the average
selling prices could reduce gross margins.

Reliance  upon  Subcontract  Manufacturing  - The vast majority of the Company's
products are manufactured and assembled by independent foundries and subcontract
manufacturers.  This reliance upon foundries and subcontractors involves certain
risks, including potential lack of manufacturing  availability,  reduced control
over delivery  schedules,  the  availability of advanced  process  technologies,
changes  in  manufacturing  yields  and  potential  cost  fluctuations.   During
downturns in the semiconductor  economic cycle,  reduction in overall demand for
semiconductor  products  could  financially  stress  certain  of  the  Company's
subcontractors.  If the financial  resources of such independent  subcontractors
are stressed,  the Company may  experience  future  product  shortages,  quality
assurance  problems,   increased  manufacturing  costs  or  other  supply  chain
disruptions.

Forecasts of Product Demand - The Company  generally must order  inventory to be
built by its foundries and subcontract  manufacturers well in advance of product
shipments.  Production is often based upon either internal or  customer-supplied
forecasts  of  demand,   which  can  be  highly  unpredictable  and  subject  to
substantial  fluctuations.  Because of the volatility in the Company's  markets,
there is risk that the Company may forecast  incorrectly  and produce  excess or
insufficient  inventories.  This  inventory  risk is  increased by the trend for
customers to place orders with shorter lead times and the customers'  ability to
cancel or reschedule existing orders.

Strategic Relationships with Customers - The Company's future success depends in
significant part on strategic  relationships  with certain of its customers.  If
these relationships are not maintained,  or if these customers develop their own
solutions,  adopt a  competitor's  solution,  or  choose  to  discontinue  their
relationships  with SMSC,  the  Company's  operating  results could be adversely
affected.

In the past, the Company has relied on its strategic  relationships with certain
customers who are technology leaders in its target markets.  The Company intends
to pursue and  continue  to form these  strategic  relationships  in the future.
These  relationships  often  require the Company to develop  new  products  that
typically involve significant technological challenges. The customers frequently
place  considerable  pressure  on the  Company to meet their  tight  development
schedules.  Accordingly, the Company may have to devote a substantial portion of
its  resources to these  strategic  relationships,  which could  detract from or
delay completion of other important development projects.

Customer Concentration - A limited number of customers account for a significant
portion of the Company's  sales and revenues.  The Company's  sales and revenues
from any one customer can fluctuate from period to period  depending upon market
demand for that customer's products,  the customer's inventory management of the
Company's products and the overall financial condition of the customer.

Shipments to Distributors - A significant portion of the Company's product sales
are made  through  distributors.  The  Company's  distributors  generally  offer
products  of  several  different  suppliers,  including  products  that  may  be
competitive with the Company's products.  Accordingly,  there is risk that these
distributors  may give higher  priority to  products  of other  suppliers,  thus
reducing  their  efforts  to sell  the  Company's  products.  In  addition,  the
Company's  agreements  with its  distributors  are  generally  terminable at the
distributor's   option.   No  assurance  can  be  given  that  future  sales  by
distributors will continue at current levels or that the Company will be able to
retain its current  distributors  on  acceptable  terms.  A  reduction  in sales
efforts by one or more of the Company's current distributors or a termination of
any distributor's  relationship with the Company could have an adverse effect on
the Company's operating results.

Business Concentration in Asia - A significant number of the Company's foundries
and  subcontractors  are located in Asia.  Many of the Company's  customers also
manufacture  in  Asia  or  subcontract   manufacturing  to  Asian  companies.  A
significant portion of the world's personal computer component and circuit board
manufacturing, as well as personal computer assembly, occurs in Taiwan, and many
of the  Company's  suppliers  and  customers  are based  in,  or do  significant
business in, Taiwan. This concentration of manufacturing and selling activity in
Asia, and in Taiwan in particular,  poses risks that could affect the supply and
cost of the Company's  products,  including currency exchange rate fluctuations,
economic and trade  policies and the political  environment  in Taiwan and other
Asian  communities.  Portions of the Asian  community have recently  experienced
health risks  associated  with the SARS virus,  the economic  impact of which is
still  unclear.  The  Pacific  Rim  region  is  also  subject  to  the  risk  of
earthquakes.   For  example,  in  September  1999,  a  major  earthquake  caused
widespread damage and business interruptions in Taiwan. While the September 1999
earthquake did not materially  adversely affect the Company's  business,  future
earthquakes  or other  natural  disasters in this region,  if they occur,  could
adversely effect the Company's operating results.

Protection  of  Intellectual  Property - The  Company has  historically  devoted
significant  resources to research and development  activities and believes that
the  intellectual  property  derived  from such  research and  development  is a
valuable  asset  that  has  been,  and will  continue  to be,  important  to the
Company's success. The Company relies upon nondisclosure agreements, contractual
provisions and patent and copyright laws to protect its proprietary  rights.  No
assurance  can be given  that the steps  taken by the  Company  will  adequately
protect its  proprietary  rights.  During its history,  the Company has executed
patent cross-licensing agreements with many of the world's largest semiconductor
suppliers,  under which the Company  receives and conveys  various  intellectual
property rights. Many of these agreements are still effective. The Company could
be adversely  affected should  circumstances  arise which cause certain of these
agreements to terminate prematurely.

Infringement  and Other Claims - Companies in the  semiconductor  industry often
aggressively protect and pursue their intellectual property rights. From time to
time, the Company has received  notices  claiming that the Company has infringed
upon or misused other parties'  proprietary  rights. The Company has also in the
past received, and may again in the future receive, notices of claims related to
business  transactions  conducted with third parties,  including asset sales and
other  divestitures.  Although the Company  defends  itself  vigorously in these
actions,  and has not  incurred  material  liabilities  under such claims in the
past, it is possible that the Company may not prevail in such actions, or in any
other such  actions,  if any, in the future.  Any  damages  resulting  from such
actions may materially and adversely  affect the Company's  business,  financial
condition and results of  operations.  In addition,  even if claims  against the
Company are not valid or successfully asserted, defense against the claims could
result in significant costs and a diversion of management and resources.

Dependence  on Key  Personnel - The success of the Company is dependent in large
part on the continued  service of its key  management,  engineering,  marketing,
sales and support employees.  Competition for qualified  personnel is intense in
the  semiconductor  industry,  and the loss of  current  key  employees,  or the
inability of the Company to attract  other  qualified  personnel,  including the
inability to offer competitive stock-based and other compensation,  could hinder
the Company's  product  development and ability to manufacture,  market and sell
its products.

The Company  believes  that stock  option  grants are critical to its ability to
attract  and retain  personnel.  Stock  option  plans are  generally  subject to
shareholder approval. From time to time, the Company seeks approval of new stock
option plans from its  shareholders,  and plans to seek a new approval for a new
option plan at its 2004 Annual Shareholder's Meeting.  SMSC's ability to hire or
retain highly qualified  personnel may be adversely  impacted by an inability to
provide  competitive  stock option grants or other  stock-based  compensation if
shareholder  approval for such plans is not obtained in a timely  manner,  or at
all.

Volatility of Stock Price - The market price of the  Company's  common stock can
fluctuate  significantly  on the basis of such  factors as the  Company's or its
competitors'  announcements  of  new  products,  quarterly  fluctuations  in the
Company's  financial results or in the financial results of other  semiconductor
companies,  changes in the  expectations  of market  analysts or  investors,  or
general conditions in the semiconductor industry or in the financial markets. In
addition,  stock  markets in general have  experienced  extreme price and volume
volatility in recent years.  This volatility has often had a significant  impact
on the stock  prices of high  technology  companies,  at times for reasons  that
appear unrelated to the company's performance.

Environmental   Regulation  -   Environmental   regulations  and  standards  are
established worldwide to control   discharges,  emissions, and solid wastes from
manufacturing  processes.  Within the United  States,  federal,  state and local
agencies establish these regulations.  Outside of the United States,  individual
countries and local governments  establish their own individual  standards.  The
Company   believes  that  its  activities   conform  to  present   environmental
regulations and the effects of this compliance have not had a material effect on
the Company's capital expenditures, operating results, or competitive position.

While to date the Company has not experienced  any material  adverse impact from
environmental  issues,  no  assurances  can be given as to the  impact of future
environmental  compliance  requirements.  Should  environmental  regulations  be
amended or an  unforeseen  circumstance  occur,  it could subject the Company to
fines,  require the Company to acquire  expensive  remediation  equipment  or to
incur other expenses to comply with environmental regulations.

Item 2.   Properties.
- ---------------------

SMSC's  headquarters  are in Hauppauge,  New York, where it owns two facilities,
and leases a third facility, totaling approximately 175,000 square feet of plant
and  office  space,  located  on  approximately  18 acres of land.  Two of these
facilities,  including the leased  facility,  totaling 130,000 square feet on 14
acres of land,  are used to  conduct  research,  development,  product  testing,
warehousing,  shipping,  marketing,  selling and administrative  activities. The
Company's other facility in Hauppauge is currently  vacant,  and the Company has
executed a contract  to sell the  facility.  Closing of this sale is expected to
occur before the end of calendar 2004.

The Company  plans to begin  construction  of an  addition  to its  headquarters
facility in  Hauppauge,  New York,  during  fiscal 2005.  The current plan is to
expand the facility from its current 80,000 square feet to approximately 200,000
square feet, allowing consolidation of the Company's Hauppauge operations into a
single facility during fiscal 2006.

In addition,  the Company  maintains  offices in leased  facilities in San Jose,
California;  Austin, Texas; Phoenix,  Arizona; Tucson, Arizona; Munich, Germany;
Tokyo,  Japan;  Taipei,  Taiwan;  Shanghai and Hong Kong, China and Seoul, South
Korea. These leases expire at various times through August 2008.


Item 3.   Legal Proceedings.
- ----------------------------

From time to time as a normal  incidence of doing  business,  various claims and
litigation   may  be  asserted  or  commenced   against  the  Company.   Due  to
uncertainties  inherent in litigation and other claims,  the Company can give no
assurance that it will prevail in any such matters, but management believes that
their ultimate resolution is not likely to have a material adverse effect on the
Company's consolidated financial position.  Nevertheless,  an adverse outcome of
any  significant  matter could have a material  adverse  effect on the Company's
consolidated results of operations or cash flows in the quarter or annual period
in which one or more of these matters are resolved.

In June 2003,  SMSC was named as a defendant  in a patent  infringement  lawsuit
filed by Analog Devices,  Inc. (ADI) in the United States District Court for the
District  of  Massachusetts  (Analog  Devices,  Inc.  v.  Standard  Microsystems
Corporation,  Case Number 03 CIV 11216). The Complaint, as amended, alleges that
some of the Company's  products  infringe one or more of three of ADI's patents,
and seeks  injunctive  relief and  unspecified  damages.  In September 2003, the
Company filed an Answer in the lawsuit,  denying ADI's  allegations  and raising
affirmative defenses and counterclaims.  The Company is vigorously defending the
lawsuit and collecting  evidence to support its defenses to infringement and its
allegations of patent invalidity and unenforceability.  Although it is premature
to  assess  the  outcome  of the  litigation,  the  Company  believes  that  the
allegations against it are without merit.

The Company was involved in an arbitration  with Accton  Technology  Corporation
(Accton) and SMC Networks, Inc. (Networks) related to claims associated with the
purchase of an 80.1%  interest in Networks by Accton from SMSC in October  1997.
In September  2003,  the  arbitration  panel issued its decision in this action,
which  directed  the release of an escrow  account to SMSC and  awarded  certain
other payments among the parties.  In December 2003, the parties reached a final
settlement  of the award,  resulting  in SMSC  receiving  $2.7  million in cash,
including the escrow account, and realizing a pre-tax gain of $0.3 million.

The Company has carried out an  evaluation  under the  supervision  and with the

the Company's disclosure controls and procedures. There are inherent limitations
to the  effectiveness  of any  system of  disclosure  controls  and  procedures,
including the possibility of human error and the  circumvention or overriding of
the controls and procedures. Accordingly, even effective disclosure controls and
procedures  can only provide  reasonable  assurance of achieving  their  control
objectives. Based upon the Company's evaluation, the Chief Executive Officer and
Chief  Financial  Officer have  concluded  that,  as of February  29, 2004,  the
disclosure controls and procedures are effective to provide reasonable assurance
that information required to be disclosed in the reports the Company files under
the  Exchange Act is recorded,  processed,  summarized  and reported as and when
required.

There  has been no change  in the  Company's  internal  control  over  financial
reporting  during the Company's  fiscal quarter  covered by this report that has
materially affected, or is reasonably likely to materially affect, the Company's
internal control over financial reporting.
