Dividends



Advantest normally pays cash dividends twice per year. Advantests board of directors recommends dividends to be paid following the end of each
fiscal year. This recommended dividend must then be approved by shareholders at the ordinary general meeting of shareholders usually held in June of each year. Immediately following approval of the dividend at the shareholders meeting,
Advantest pays the dividend to holders of record as of the preceding March 31. In addition to these year-end dividends, Advantest may pay interim dividends in the form of cash distributions from its retained earnings to its shareholders of record as
of September 30 in each year by resolution of its board of directors and without shareholder approval. Advantest normally pays interim dividends in December.



The following table sets forth the dividends paid by Advantest for each of the periods shown. The periods shown are the six months ended on that date. The
U.S. dollar equivalents for the dividends shown are based on the exchange rate in Japan on each record date shown.

Risks Related to Advantests Business



Advantests business and results of operations are subject to significant cyclicality in the semiconductor industry



Advantests business depends largely upon the capital expenditures of
semiconductor manufacturers, test houses and foundries. These manufacturers and companies, in turn, determine their capital expenditure and investment levels largely based on current and anticipated market demand for semiconductors and demand for
products incorporating semiconductors. Historically, the percentage reduction in capital expenditures by semiconductor manufacturers during downturns in the semiconductor industry, including investment in test system, has typically been much greater
than the percentage reduction in worldwide sales of semiconductors. The semiconductor industry has been highly cyclical with recurring periods of excess inventory, which often have had a severe effect on the semiconductor industrys demand for
semiconductor and component test systems and other test systems, including those of Advantest. The market for memory semiconductors, or semiconductors that contain only memory circuits, is especially cyclical as compared to non memory
semiconductors, or semiconductors that contain circuits other than memory circuits. In fiscal 2004, approximately 69% of Advantests net sales from semiconductor and component test systems were derived from the sale of semiconductor test
systems for memory semiconductors. Therefore, any cyclical downturns in the memory semiconductor market will likely adversely affect Advantests business more than its competitors selling a lower proportion of memory semiconductors.

##### Table of Contents

The worldwide semiconductor market contracted significantly in the second half of 2000 and during 2001
and grew by only 1.3% in 2002 compared to 2001. The semiconductor market recovered significantly, however, recording 18.3% growth in 2003 and 28.0% growth in 2004. Worldwide sales of memory semiconductors, which declined by 49.5% in 2001 as compared
with 2000, increased by 8.7% in 2002 as compared with 2001 and further increased by 20.2% and 45.0% in 2003 and 2004, respectively on a year-on-year basis, primarily due to the increase in demand for flash memory semiconductors used in digital
consumer products and for DRAM semiconductors used in personal computers. Worldwide sales of non memory semiconductors, which declined by 26.5% in 2001 compared to 2000, declined by 0.4% in 2002 as compared with 2001, but increased by 17.8% and
23.9% in 2003 and 2004, respectively on a year-on-year basis, primarily due to the increase in demand for personal computers and other digital consumer products such as digital cameras, digital versatile disc, or DVD recorders and digital
televisions. However, the net sales of memory semiconductors and non memory semiconductors became sluggish after the summer of 2004 due to inventory adjustment by semiconductor manufacturers.



The cyclicality of the market for semiconductors is affected by various
factors such as:



| |  |  | the overall state of the global economy;
| | - |  | ----------------------------------------



| |  |  | the consumer demand for digital consumer products such as digital cameras and DVD recorders;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | the sales levels in the personal computer industry;
| | - |  | ---------------------------------------------------



| |  |  | the levels of investment in communications infrastructure and the effect on the mobile telephone industry; and
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | currency exchange rate fluctuations.
| | - |  | ------------------------------------



After recording record sales and profits in fiscal 2000, Advantest experienced a 65.6% decrease in net sales in fiscal 2001 and an increase of 2.6% in
fiscal 2002. In fiscal 2003, due to the recovery of investments in semiconductors, Advantest recorded an increase of 78.2% compared to fiscal 2002. Net sales for the first half of fiscal 2004 was of ¥146,589 million, which is the highest net
sales Advantest achieved in any interim six-month period. Reflecting the adjustment of excess inventories by semiconductor manufacturers, however, net sales for the second half of fiscal 2004 dropped to ¥92,850 million. Net sales for the full
fiscal 2004 stood at ¥239,439 million, representing a 37.4% increase over fiscal 2003 and contributing to current net income of ¥38,078 million.



Advantest believes that despite the recovery from fiscal 2003, its semiconductor and component test system business and mechatronics system business will
continue to be susceptible to the highly cyclical nature of the semiconductor industry, including the volatile nature of the personal computer and communications industry. Advantest also believes that a part of the semiconductor and component test
system business will continue to be affected by uncertainties about capital expenditures in wireless communications and optic fiber networks worldwide. Accordingly, Advantests financial condition and results of operations may be adversely
affected in the event of significant downturn in, among others, the semiconductor industry and the communications industry.



If Advantest does not introduce new products meeting its clients technical requirements in a timely manner and at a competitive price, its products will
become obsolete, and its financial conditions and results of operations will suffer



Advantest sells its products to several industries that are characterized by rapid technological changes, frequent new product and service introductions, varying and unpredictable product lifecycles and evolving
industry standards. Advantest anticipates that future demand for its products will be driven, in large part, by advances in semiconductor technology, which create new testing requirements that are not adequately addressed by currently installed
semiconductor test systems. These advances and customers needs include:



| |  |  | the introduction of system-on-a-chip or SoC semiconductors that incorporate more advanced memory, logic and analog circuits;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



4



---

##### Table of Contents

| |  |  | investment by memory semiconductor manufacturers in facilities that are used to produce next generation memory semiconductors such as DDR3 and DDR2-SDRAM;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | investment by semiconductor manufacturers in mechatronics related products which transport devices faster, more accurately and more stably;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the use of self-test technologies that employ circuit designs incorporated into the circuits of semiconductor chips; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | prompt response and quick repair in the event of failure.
| | - |  | ---------------------------------------------------------



Advantest also believes demand for its products including semiconductor and component test systems, will be strongly affected by the level of demand for
personal computers, high-speed wireless and wireline data services and digital consumer products. Advances in technologies used in those products and services frequently require new testing systems. Without the timely introduction of semiconductor
test systems capable of effectively testing and measuring equipment that use new technologies, Advantests products and services will become technologically obsolete over time.



The failure of Advantest to meet its customers technical requirements at a competitive price or to deliver conforming
equipment in a timely manner can result in its products being replaced by equipment of a competitor or an alternative technology solution. Accordingly, Advantests inability to provide a product that meets requested performance criteria at an
acceptable cost when required by its customer would severely damage its reputation with that customer and could adversely affect future sales efforts with respect to that customer.



Advantest may not recoup costs incurred in the development of new products



Enhancements to existing products and the development of new generations of
products are, in most cases, costly processes. Furthermore, because the decision to purchase products of semiconductor and component test systems and mechatronics systems generally involves a significant commitment of capital, the sale of this
equipment typically involves a lengthy sales period and requires Advantest to expend substantial funds and sales efforts to secure the sale. Advantests enhancements or new generations of products may not generate net sales in excess of
development and sales costs if, for example, these new enhancements or products are quickly rendered obsolete by changing customer preferences, the introduction by Advantests competitors of products embodying new technologies or features, the
introduction by Advantests customers of new products that require different testing functions or the failure of the market for Advantests customers products to grow at the rate, or to the levels, anticipated by Advantest. This risk
is particularly acute with respect to test systems for SoC semiconductors because, in general, new SoC semiconductors product lines are introduced to market more frequently than new memory semiconductor product lines. In some cases, Advantest must
anticipate industry trends and develop products in advance of the commercialization of its customers products. This requires Advantest to make significant investments in product development well before it determines the commercial viability of
these innovations. If Advantests customers fail to introduce their devices in a timely manner or the market rejects their devices, Advantest may not recover its investments in product development through sales in significant volume.



Advantest faces aggressive competition, in all areas of its businesses,
and if Advantest does not compete effectively, its business may be harmed



Advantest faces substantial competition throughout the world. Advantests primary competitors in the semiconductor and component test system market include, among others, Teradyne, Inc., Agilent Technologies,
Inc. and Yokogawa Electronic Corporation. In the mechatronics system market, Advantest has also been competing with Delta Design and Yokogawa Electronic Corporation. In addition, in the services, support and others segment, Advantest has been
competing with competitors providing similar businesses. Some of Advantests competitors have greater financial and other resources than Advantest.

##### Table of Contents

Advantest faces many challenges in its businesses, including increased pressure from customers to produce
semiconductor and component test systems and mechatronics systems that reduce testing costs. Advantest must continue to enhance its business processes to lower the cost of its products, as well as introduce enhancements that otherwise lower overall
testing costs, to compete successfully. Advantest also expects its competitors to continue to introduce new products with improvements in price and performance, as well as increase their customer service and support offerings. Significant increases
in competition may erode Advantests profit margin and weaken its earnings.



Advantests product lines are facing significant price pressure



Price pressure in Advantests businesses is adversely affecting Advantests operating margins. Advantest believes that price pressure with respect to semiconductors continues to grow even during periods when
demand, in terms of volume, for semiconductors is increasing, and thus there exists continuous pressure on the market price for products in the Semiconductor and Component Test System Segment and Mechatronics System Segment. During these periods,
Advantests customers such as semiconductor manufacturers and testing companies seek to increase their production capacities, while minimizing their capital expenditures at the same time. Advantest believes that there still exists demand for
short-term product delivery and implementation, despite the continued recovery in the semiconductor market since fiscal 2003. In addition, increased competition in the market for digital consumer products and personal computers drove down prices of
these goods, subsequently creating significant price pressure on Advantests product lines. A further increase in price pressure will adversely affect Advantests future financial conditions and results of operations.



Advantests market position in test systems for SoC semiconductors creates
challenges for Advantest to grow its business



Advantests market share in test systems for SoC semiconductors was 11.3% and 16.8% in 2003 and 2004, respectively. Despite the increase in the market share, however, Advantest has continued to face challenges to attaining a
predominant presence in the market for test systems for SoC semiconductors. Customers typically purchase new semiconductor and component test systems from current system suppliers because they want to ensure that new equipment is compatible with
their existing systems. In addition, the development of new semiconductor and component test systems is, in general, a cumulative process, which means established manufacturers enjoy competitive advantages based on technology and know-how already
acquired. Advantest believes that increasing sales of test systems for SoC semiconductors is vital to growing its overall business. According to data in recent years, the market for test systems for SoC semiconductors has been approximately 1.5
times as large as the market for test systems for memory semiconductors on a market value basis. Advantest may need to reduce sales prices for its test systems for SoC semiconductors, and, therefore, deteriorate its margins from current levels in
order to grow its test systems for SoC semiconductors business.



Advantest may not recoup its investment in OPENSTAR®, as it may not be broadly accepted, or otherwise benefit from the successful adoption of, OPENSTAR®



Advantest is now striving to enhance the adoption of OPENSTAR®, an industry-wide, open architecture, because it believes that OPENSTAR® will provide an opportunity for late entrants to the test systems for SoC semiconductors market, such as Advantest, to
increase their market share and thus improve their operation results.



However, even if OPENSTAR® is broadly
accepted by the semiconductor industry, the consequences of the adoption of OPENSTAR® on Advantests business are uncertain. OPENSTAR® is an open architecture that allows all semiconductor industry participants to use, therefore the adoption of the new standard could result in the increase of the number of market
participants and in a loss of market share for Advantest. In addition, OPENSTAR® is a new standard that will require all test system manufacturers, including Advantest, to re-design their products. There can be no assurance that Advantest will be able to design and manufacture products based

##### Table of Contents

on this new standard that meet the cost and technical requirements of SoC semiconductor manufacturers. These and other uncertainties that can result from the
adoption of OPENSTAR® could adversely affect
Advantests test systems for SoC semiconductors business.



The
market for Advantests major products is highly concentrated, and Advantest may not be able to increase sales of its products because of limited opportunities



In particular the market for test systems for memory semiconductors in the semiconductor and component test system segment
is highly concentrated, with a small number of large semiconductor manufacturers, test houses and foundries accounting for a large portion of total sales in the semiconductor test system industry. Advantest believes that this state of the market
will become even more severe in the future as a move towards consolidation in the semiconductor industry has recently begun, with larger semiconductor device manufacturers, foundries and test houses acquiring smaller, often financially-troubled,
semiconductor market participants. Advantests ability to increase sales will depend in large part upon its ability to obtain or increase orders from large-volume customers.



Advantests largest customers currently account for a significant part of its net sales, and the loss of one or more of these
customers could harm its business



Advantests
success depends on its continued ability to develop and manage relationships with its major customers, a small number of which currently accounts for a significant portion of its net sales. Sales to the Advantests largest customer as a
percentage of its total sales were approximately 12% in fiscal 2002 and 2003, and approximately 15% in fiscal 2004. Sales to the Advantests five largest customers accounted for approximately 38% of total net sales in fiscal 2002, approximately
37% in fiscal 2003, and approximately 42% in fiscal 2004. The loss of one or more of these major customers could materially harm Advantests business.



Fluctuations in exchange rates could reduce Advantests profitability



Advantest derives a majority of its net sales from products sold to customers located outside of Japan. Approximately 75% of
Advantests fiscal 2004 net sales were from products sold to overseas customers. Most of Advantests products are manufactured in Japan, but approximately 31 % of Advantests net sales in fiscal 2004 were made in currencies other than
the yen, predominantly the U.S. dollar. A strengthening in the yen relative to the U.S. dollar and, to a much lesser extent, currencies of those other countries where Advantest sells its products would increase the prices of Advantest products as
stated in U.S. dollars and in those other currencies and could hurt sales in those countries. In addition, significant fluctuations in the exchange rate between the yen and foreign currencies, especially the U.S. dollar, could require Advantest to
lower its prices with respect to foreign sales of its products that are priced in yen, and reduce the yen equivalent amounts of its foreign sales for products that are based in U.S. dollars or other foreign currencies, and thus reduce its
profitability. These fluctuations could also cause prospective customers to push out or delay orders because of the increased relative cost of Advantests products. In the past, there have been significant fluctuations in the exchange rate
between the yen and the currencies of countries in which Advantest does business.



The failure by Advantest to meet demand for its products upon a significant recovery in the semiconductor and component test systems market and mechatronics system market would likely adversely affect its future market share and
financial results



If the market for semiconductor and
component test systems and mechatronics systems were to experience a large increase in demand similar to that experienced in 2000, Advantest would require a significant increase in production capabilities, including personnel, in order to fully
capitalize on such a recovery. The failure of Advantest to adjust to such unanticipated increases in demand for its products during any such a recovery could result in Advantest losing one or more of its existing large-volume customers or losing the
opportunity to establish a strong relationship with large-volume customers with which it currently does little or no business. Any such failure would likely adversely affect Advantests future market share and its financial results.

Advantests dependence on subcontractors and on sole source or a limited number of suppliers for its
components and parts may prevent it from delivering an acceptable product on a timely basis



Advantest relies on subcontractors to perform the low-end assembly requirements for its products. For example, Advantest has been outsourcing the assembly
of the numerous circuit boards. In addition, many of the components used in Advantests semiconductor and component test systems and mechatronics systems are produced by suppliers based on Advantests specifications. Advantests
reliance on these subcontractors and suppliers gives it less control over the manufacturing process and exposes it to significant risks, especially inadequate manufacturing capacity, late delivery, substandard quality, lack of labor availability and
high costs. In addition, Advantest depends on sole source, or a limited number of, suppliers for a portion of its components and parts. Advantest does not maintain long-term supply agreements with most of its suppliers, and it purchases most of its
components and parts through individual purchase orders. If suppliers become unable to provide components or parts in the volumes needed and at acceptable prices, Advantest would have to identify and procure acceptable replacements. Furthermore, the
markets for semiconductors and other specialized components have, in the past, experienced periods of inadequate supply to meet demand. The process of selecting subcontractors or suppliers and of identifying suitable replacement components and parts
is a lengthy process and can result in Advantest being unable to deliver products meeting customer requirements on a timely basis. Advantest has, in the past, been unable to deliver its products according to production schedules due to the inability
of suppliers to supply components and parts based on Advantests specifications and due to other shortages in components and parts.



If Advantests main facilities for research and development, production or information technology systems for all of the Advantests businesses, or the
facilities of its subcontractors and suppliers, were to experience catastrophic loss, its results of operations would be seriously harmed



Advantests main facilities for research and development for its semiconductor and component test systems and mechatronics systems segments
production, as well as many of Advantests services bases, are located in Japan. In addition, the main system server and parts of the network hub are maintained in system centers approved by the Information System Management System, or ISMS,
and local network servers are located in operations offices throughout Japan. Japan suffers from relatively frequent earthquake activity.



If Advantests facilities, particularly its semiconductor and component test system manufacturing plant, were to experience a catastrophic loss, it
would materially disrupt Advantests operations, delay production, shipments and revenue, and result in large expenses to repair or replace the facility. Advantest has insurance to cover most potential losses at its manufacturing facilities,
other than those that result from earthquakes. However, this insurance may not be adequate to cover all possible losses. Similar disruptions to Advantests business may occur if the facilities of Advantests subcontractors and suppliers or
if the facilities of Advantests information system network were to experience a catastrophic loss.



Advantests business is subject to economic, political and other risks associated with international operations and sales



Advantests business is subject to risks associated with doing business internationally because it sells its products,
and purchases parts and components from, around the world. In fiscal 2004, 60.2% of Advantests total net sales came from Asia (excluding Japan), a majority of which consists of sales in Taiwan, the Peoples Republic of China and Korea,
9.6% from the Americas and 5.1% from Europe. Advantest anticipates that net sales from international operations will continue to represent a substantial portion of its total net sales. In addition, some of Advantests distribution and support
subsidiaries are located in the Americas, Europe, and Asian countries including Singapore, Taiwan, the Peoples Republic of China and Korea and some of Advantests suppliers are also located overseas. Accordingly, Advantests future
results could be harmed by a variety of factors, including:



| |  |  | political and economic instability, natural calamities or other risks related to countries where Advantest manufactures its products, procures its components and parts or sells its
products;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Advantests financial conditions and results of operations are subject to factors relating to its marketing and sales
capabilities and its branding



Advantests
financial conditions and results of operations are negatively affected by factors relating to its marketing and sales capabilities and its branding, including:



| |  |  | the long selling process involved in the sale of semiconductor and component test systems;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | the relatively small number of total units sold in the semiconductor and component test system market;

| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | uncertain market acceptance of products developed by its customers.
| | - |  | -------------------------------------------------------------------



Chemicals used by Advantest may become subject to more stringent regulations, and Advantest may be required to incur significant cost in adapting to new
requirements



Advantest uses chemicals, the
manufacture, processing and distribution of which are subject to environmental related laws, regulations and rules of Japanese governmental agencies, as well as by various industry organizations and other regulatory bodies in other countries. These
regulatory bodies may strengthen existing regulations governing chemicals used by Advantest and may also commence regulation of other chemicals used by Advantest. For example, Advantest uses lead solder for mounting electronic parts and components
for its products. Beginning August 2005, the European Union will implement regulations on the collection, treatment, recycling and recovery of electrical and electronic equipment waste and beginning July 2006, will implement regulations on the usage
of lead, mercury, cadmium and other hazardous substances in electrical and electronic equipment. Further, to cool its semiconductor and component test systems, Advantest uses a particular type of perfluorocarbon, or PFC, that is regulated by the law
in Japan and certain other countries. Advantest believes that it is in compliance with current regulations; however, Advantest must be prepared to adapt to regulatory requirements in all relevant countries as requirements change. Advantest may be
required to incur significant cost in adapting to new requirements. Any failure by Advantest to comply with applicable government or industry regulations could result in the imposition of fines or restrictions on its ability to carry on or expand
its operations.



Third parties may claim Advantest is infringing their
intellectual property, and Advantest could suffer significant liabilities, litigation costs or licensing expenses or be prevented from selling its products



Advantest may be unknowingly infringing the intellectual property rights of third parties and may be held responsible for
that infringement. To date, Advantest has not been the subject of a material intellectual property claim. However, any future litigation regarding patents or other intellectual property infringement could be costly and time consuming, and divert
management and key personnel from Advantests business operations. If

##### Table of Contents

Advantest loses a claim, it might be forced to pay significant damages, pay license fees, modify its products or processes, stop making products or stop
using processes. A license could be very expensive to obtain or may not be available at all. Changing Advantests products or processes to avoid infringing the rights of third parties may be costly or impractical.



Advantest may be unable to protect its proprietary rights due to the difficulty of
Advantest gaining access to, and investigating, the products believed to infringe Advantests intellectual property rights



Advantest relies on patents, utility models, design rights, trademarks and copyrights obtained in various countries to actively protect its proprietary
rights. For instance, with respect to the device interface market, Advantest has taken legal actions based on its patent and utility model rights against manufacturers that sell replicas of Advantests products and, in some instances, have
obtained injunctions against sales of replicas. However, in general, it is difficult for Advantest to gain access to, and investigate, the products believed to infringe Advantests intellectual property rights. Therefore, Advantest cannot
ensure that its intellectual property rights will provide meaningful protection of its proprietary rights. Nevertheless, Advantest is focused on protecting its intellectual property rights from third party infringement and will continue to monitor
and police its rights.



The current technology labor market is very
competitive, and Advantests business will suffer if Advantest is unable to hire and retain engineers and other key personnel



Advantests future success depends partly on its ability to attract and retain highly qualified engineers for its research and development and
customer service and support divisions. If Advantest fails to hire and retain a sufficient number of these personnel, it will not be able to maintain and expand its business. Advantest may need to revise its compensation and other personnel related
policies to retain its existing officers and employees and attract and retain the additional personnel that it expects to require.



Investor confidence and the value of ADRs and ordinary shares may be adversely impacted if Advantests independent registered public accounting firm is unable
to provide adequate attestation over the adequacy of the internal control over Advantests financial reporting as of March 31, 2007 as required by Section 404 of the Sarbanes-Oxley Act of 2002.



The Securities and Exchange Commission, as directed by Section 404 of the
Sarbanes-Oxley Act of 2002, adopted rules requiring public companies to include a report of management on the companys internal control over financial reporting in its Annual Report on Form 10-K or Form 20-F, as the case may be, that contains
an assessment by management of the effectiveness of the companys internal control over financial reporting. In addition, the companys independent registered public accounting firm must attest to and report on managements assessment
of the effectiveness of the companys internal control over financial reporting. These requirements will first apply to Advantests Annual Report on Form 20-F for the fiscal year ending March 31, 2007. Although Advantest intends to
diligently and vigorously review its internal controls over financial reporting in order to ensure compliance with Section 404 requirements, if Advantests independent registered public accounting firm is not satisfied with Advantests
internal control over our financial reporting or the level at which our controls are documented, designed, operated or reviewed, then they may decline to attest to managements assessment or may issue a report that is qualified. Any of these
possible outcomes could result in an adverse reaction in the financial marketplace due to a loss of investor confidence in the reliability of our financial statements, which ultimately could negatively impact the market price of Advantests
ADRs and ordinary shares.

Risks Related to Ownership of ADSs or Common Stock



Yen-dollar fluctuations could cause the market price of the ADSs to decline and reduce dividend amounts payable to ADS holders as
expressed in U.S. dollars



Fluctuations in the
exchange rate between the Japanese yen and the U.S. dollar will affect the U.S. dollar equivalent of the Japanese yen price of the shares on the Tokyo Stock Exchange and, as a result, are likely to affect the market price of the ADSs. Advantest has
historically paid dividends on its shares twice a year. If Advantest declares cash dividends, dividends on the shares represented by the ADSs will be paid to the depositary in Japanese yen and then converted by the depositary into U.S. dollars.
Therefore, exchange rate fluctuations will also affect the dividend amounts payable to ADS holders following conversion into U.S. dollars of dividends paid in Japanese yen on the shares represented by the ADSs.



As a holder of ADSs, you will have fewer rights than a shareholder has, and you must
act through the depositary to exercise those rights



The rights of shareholders under Japanese law to take actions, including voting their shares, receiving dividends and distributions, bringing derivative actions, examining Advantests accounting books and records and exercising
appraisal rights, are available only to holders of record on Advantests register of shareholders or Advantests register of beneficial shareholders. Because the depositary, through its custodian agents, is the registered holder of the
shares underlying the ADSs, only the depositary can exercise those rights in connection with the deposited shares. The depositary will make efforts to vote the shares underlying a holders ADSs as instructed by the holder and will pay to the
holder the dividends and distributions collected from Advantest. However, in the holders capacity as an ADS holder, that holder will not be able to bring a derivative action, examine Advantests accounting books and records or exercise
appraisal rights through the depositary.



There are restrictions on the
withdrawal of shares from Advantests depositary receipt facility



Under Advantests ADS program, each ADS represents the right to receive one-fourth of one share. To withdraw any shares, a holder of ADSs has to surrender for cancellation American Depositary Receipts, or ADRs,
evidencing 400 ADSs or any integral multiple thereof. Each ADR bears a legend to that effect. As a result, holders of ADSs are unable to withdraw fractions of shares or units or receive any cash settlement from the depositary in lieu of withdrawal
of fractions of shares or units. Holders of shares representing less than one unit, or 100 shares, may require Advantest to repurchase those shares, whereas holders of ADSs representing less than one unit of shares are unable to exercise this right
because the holders of these ADSs are unable to withdraw the underlying shares. Under Advantests ADS program, an ADS holder cannot cause the depositary to require Advantest to repurchase fractions of shares or units on its behalf. For a
further discussion of the ADSs and the ADS program, see Description of American Depositary Receipts set forth in Advantests registration on Form F-1 filed with the Securities and Exchange Commission on July 22, 2002. For a further
discussion of the Japanese unit share system, see Additional InformationMemorandum and Articles of AssociationThe Unit Share System.



Enforcement of Civil Liabilities



Advantest is a limited liability, joint-stock corporation incorporated under the laws of Japan. Almost all of Advantests directors, executive
officers and corporate auditors reside in Japan. All or substantially all of Advantests assets and the assets of these persons are located in Japan and elsewhere outside the U.S. It may not be possible, therefore, for investors to effect
service of process within the U.S. upon Advantest or these persons or to enforce against Advantest or these persons judgments obtained in U.S. courts predicated upon the civil liability provisions of the federal securities laws of the U.S.
Advantests Japanese counsel, Nagashima Ohno & Tsunematsu, has advised Advantest that there is doubt as to the enforceability in Japan, in original actions or in actions for enforcement of judgments of U.S. courts, of liabilities predicated
solely upon the federal securities laws of the U.S.

ITEM 4.    INFORMATION ON THE COMPANY



|4.A | HISTORY AND DEVELOPMENT OF THE COMPANY
|--- | --------------------------------------



Advantest commenced operations in July 1954, and was incorporated in December 1954 under the name Takeda Riken Industry Co., Ltd. as a limited liability,
joint-stock company in Japan under the Commercial Code of Japan. At the time of incorporation, Takeda Rikens primary business was the design, manufacture and sale of measuring instruments for Japanese electronics manufacturers. Takeda Riken
started focusing on semiconductor test equipment for the semiconductor industry in 1968 and was the first to domestically produce semiconductor test equipment in 1972. In 1971, Takeda Riken entered into its first distribution agreement with a
foreign distributor, and in 1973, established its first representative office in the U.S. to gather information on technology and distribution and to establish dealer relationships. These two milestones launched the companys long-term goal of
becoming a global manufacturer of testing and measuring products. Takeda Riken has been listed on the Tokyo Stock Exchange since February 1983. Takeda Riken changed its registered name to Advantest Corporation in October 1985.



Advantest applies its capital expenditures chiefly to the streamlining of
development, production of new products, energy saving initiatives and the expansion of production capacity, to the level of ¥7.5 billion, ¥5.6 billion and ¥9.3 billion in fiscal 2002, 2003 and 2004, respectively.



The largest capital investment in recent years was the construction of the
Kita-Kyushu R&D Center, a new research and development facility in Fukuoka prefecture, completed in June 2002. The total cost of this facility was approximately ¥1.5 billion.



As of June 1, 2005, Advantest does not have any major capital expenditures in progress.



Advantests principal executive offices are located at Shin-Marunouchi
Center Building, 1-6-2, Marunouchi, Chiyoda-ku, Tokyo 100-0005 Japan. Advantests telephone number in Japan is (81-3) 3214-7500. Advantests principal executive office relocated to the above address from Shinjuku-ku, Tokyo in September
2004.

Industry Overview



Advantest offers products in semiconductor and component test systems,
mechatronics systems, and services, support and others. Advantests main customers are semiconductor and electronic components manufacturers, foundries and test houses. Advantest believes that the following factors will promote growth of the
business carried out by its main customers.



| |  |  | the move to lower-cost, smaller, faster and more powerful and energy efficient semiconductors and electronic components;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | the increase in demand for higher performance servers and personal computers;
| | - |  | -----------------------------------------------------------------------------



| |  |  | the increase in demand for digital consumer products such as flat panel display televisions, DVD recorders and digital cameras;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | emergence of new models of high-performance game machines;
| | - |  | ----------------------------------------------------------



| |  |  | the increasing levels of wireless communications penetration worldwide due to the expansion of the mobile phone industry;

Advantest believes that these factors will also continue to provide it with
long-term growth opportunities because such factors will lead to a growing appetite for capital expenditures by its customers, resulting in an expansion of businesses for Advantest. However, such capital expenditures of the customers may be affected
by the following factors, and Advantests performance results may accordingly be adversely affected;



| |  |  | the level of demand for semiconductors and electronic components;
| | - |  | -----------------------------------------------------------------



| |  |  | advancements in semiconductor and electronic components technology; and
| | - |  | -----------------------------------------------------------------------



| |  |  | changes in semiconductor and electronic components manufacturing processes.
| | - |  | ---------------------------------------------------------------------------



Demand for Semiconductors and Electronic Components



Demand for semiconductor and component test systems and mechatronics systems is closely tied to the volume of semiconductors
and electronic components produced and the resulting capital expenditure of semiconductor manufacturers and others.



Semiconductors are generally classified as either memory semiconductors or non memory semiconductors. Memory semiconductors are used in electronic systems
to store data and programs. Non memory semiconductors include various semiconductors that incorporate non memory circuits, which include logic and analog circuits. Logic circuits process digital data to control the operations of electronic systems.
Analog circuits process analog signals translated from real world phenomena such as sound, light, heat and motion. SoC semiconductors are a subset of non memory semiconductors that combine advanced logic circuits with analog and/or memory circuits
on a single chip. SoC semiconductors are used in a variety of sophisticated products, including wireless communications, fiber optic equipments and digital consumer products.



Semiconductor sales have increased significantly over the long-term. However, semiconductors, and in particular memory
semiconductors, have experienced significant cyclical variations in growth rates. According to World Semiconductor Trade Statistics, the worldwide sales of all semiconductors increased from approximately $50 billion in 1990 to approximately $204
billion in 2000, with cycles of growth and contraction occurring during the period. In 2001, worldwide semiconductor sales fell by approximately $65 billion, or approximately 32%, compared to the previous year to approximately $139 billion. While
sales in 2002 increased only marginally compared to the previous year, sales climbed sharply by approximately $25 billion or 18% compared to the previous year to $166 billion in 2003. Sales in 2004 increased by approximately $46.6 billion or 28% to
$213 billion, compared to the previous year. The following table sets forth the size of the market for memory semiconductors, non memory semiconductors (including SoC semiconductors) and all semiconductors between 1998 and 2004 and the projected
market size between 2005 and 2007 as compiled and estimated by World Semiconductor Trade Statistics as of May 2005.

The market for
semiconductors improved significantly in 1999 and the first half of 2000. However, in the second half of 2000, market prices for both memory semiconductors and SoC semiconductors began to decrease significantly. This downturn continued and deepened
throughout 2001, and despite increased demand generated by some segments of the digital consumer electronics market, in particular the digital cameras, DVD recorder

##### Table of Contents

and high-end wireless handset markets, market prices for semiconductors remained depressed and the overall market for semiconductors remained weak in 2002.
This weakness of demand was a result of, among other factors, the global economic downturn, sluggish sales of personal computers and continued low levels of investment in communications infrastructure.



The non memory semiconductor market is less volatile than the memory
semiconductor market because these semiconductors are used in a larger variety of consumer products and equipment. In periods of rapid decline in the semiconductor market, the capital expenditures of semiconductor manufacturers, including their
purchases of test systems, generally decline at a faster pace than the decline in semiconductor sales. In addition, sales of test systems generally do not experience significant increases following a downturn in the semiconductor market until
semiconductor manufacturers determine that the market for semiconductors is experiencing a real recovery.



It appears that the semiconductor market bottomed out in the second half of fiscal 2001 and then improved through fiscal 2002, fiscal 2003, and the first
half of fiscal 2004. However, Advantest believes that there exists a substantial lack of visibility regarding semiconductor demand, as the market appears to have slowed down beginning in the second half of fiscal 2004 due to the inventory
adjustment. According to data published by World Semiconductor Trade Statistics as of May 2005, the market for memory semiconductors will cycle between growth and contraction and grow at a compound annual growth rate of approximately 1.5% over the
next three years to approximately $49.4 billion in 2007. Advantest believes that demand for memory semiconductors will be generated in the foreseeable future by the prevalence of next generation double data rate synchronous dynamic random access
memory semiconductors, or DDR-SDRAM, such as DDR2-SDRAM, DDR3-SDRAM, flash memory and other high-end semiconductors. While World Semiconductor Trade Statistics estimates that the non memory semiconductor market will grow at a compound annual growth
rate of approximately 8.9% over the next three years to approximately $214 billion in 2007. Advantest believes that the demand for non memory semiconductors will generally grow in the foreseeable future, led by the further prevalence of digital
consumer products, including flat panel display televisions, DVD recorders, and the new developments in personal computers or high performance mobile phones.



Advancements in Semiconductor and Electronic Component Technology



Advantest believes that demand for semiconductor and component test systems and mechatronics systems is also affected by the
rate of change and development in semiconductor and electronic component technology. Current changes in the semiconductor and electronic component industry relate to the innovation of digital consumer products and communications technologies. Demand
for faster semiconductors and electronic components that are smaller in size, incorporate more functions and require less power to operate is being driven by:



| |  |  | growing demand for, and continuous improvements in, consumer electronics products, such as flat-panel display televisions, DVD recorders, digital cameras, television game consoles
and mobile phone handsets; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | requirements of communications network equipment, such as network routers, switches and base stations, as well as wireless handsets and other Internet access devices, to enable
advances in Internet hardware and software applications, increases in infrastructure performance and simplification and miniaturization of Internet access devices.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Demand for personal computers and servers with higher performance and capabilities is also driving changes in the memory
semiconductor sector. These demands are causing manufacturers to shift to the production of next generation memory semiconductors that allow higher-speed data transfer, such as DDR2-SDRAM and DDR3-SDRAM. Advantest believes that this shift is
creating demand for test systems for memory semiconductors capable of handling these new types of memory semiconductors. In addition, Advantest believes that a new demand for mechatronics systems, including test handlers and device interfaces
connecting semiconductor devices and test systems, will be created and will grow in line with advances in semiconductor technologies.

##### Table of Contents

The development of SoC semiconductors with lower cost, smaller size, higher performance and lower power
consumption has created demand for sophisticated semiconductor and component test systems that can simultaneously test SoC semiconductors logic, analog and memory circuits. Further innovations in non memory semiconductor technologies including
SoC semiconductor technology are expected, and Advantest believes these innovations will create demand for new, high-performance semiconductor and component test systems optimized for use with these advanced semiconductors.



Advantest also believes that the integration of SoC semiconductors into a
range of digital consumer products will drive demand for low-cost test systems for SoC semiconductors. SoC semiconductors are often customized for applications in specific products, which results in a large variety of SoC semiconductors that are
often produced in relatively smaller volumes.



Changes in
Semiconductor and Electronic Component Manufacturing Technologies



Semiconductor and electronic component manufacturers are promoting production outsourcing, technological innovation in manufacturing processes and testing technology to improve productivity.



Production Outsourcing



In recent years, semiconductor manufacturing and testing processes have
become more complex and capital intensive. As a result, an increasing portion of the manufacturing and testing functions are being subcontracted out, in particular by companies that design, but outsource the production of, semiconductors, namely
fabless design companies, in order to reduce fixed costs. This trend has resulted in an increase in the number of test houses that accept test process outsourcing and foundries that accept manufacturing process outsourcing. Foundries either perform
testing in-house or outsource their testing needs to test houses. This trend towards production outsourcing, particularly to test houses, has increased the number of potential customers for semiconductor and component test system manufacturers,
although it has not significantly affected total demand for Advantests products. In addition, Advantest believes that foundries and test houses require semiconductor and component test systems which have been used for the product lines of
multiple semiconductor designers. Advantest believes this compatibility requirement gives semiconductor and component test system manufacturers with broader product lines and larger market shares an advantage over smaller competitors. Outsourcing
has also been utilized for electronic component manufacturing.



Technological Innovation in Manufacturing Process



One of the recent innovations in semiconductor manufacturing processes is the production of semiconductors using 300 millimeter wafers. Wafers are circular flat pieces of silicon from which multiple semiconductor chips are constructed using
photo-etching and other manufacturing processes. The use of 300 millimeter wafers will allow manufacturers to increase average semiconductor production per wafer by 125% when compared to production using conventional 200 millimeter wafers. Many
manufacturers announced delays in investment in 300 millimeter wafer plants beginning in the second half of 2000 due to negative trends in the semiconductor market. However, investment in these plants by some manufacturers resumed at the end of
2002, investment continued to increase during 2003 and 2004 and is expected to continue to increase during 2005. Investment in these facilities is expected to lead to demand for new semiconductor and component test systems and test handlers with
increased throughput capabilities for semiconductor manufacturers to capture fully the cost efficiencies associated with the use of 300 millimeter wafers.



New Testing Technologies



Semiconductor designers and manufacturers are striving to further reduce costs through the development of self-test technologies. Self-test technologies
are designed into circuits which are added on to semiconductor chips and simplify testing process and reduce the aggregate time and cost required for testing. However, Advantest



16

##### Table of Contents

believes that testing using self-test technologies is less reliable than that using semiconductor and component test systems. Advantest believes that
self-test technologies will be used primarily in flash memory semiconductors and high value-added semiconductors, such as certain SoCs, that are expected to have large future production volumes.



Advantest believes that semiconductor and electronic component manufacturing
processes will continue to evolve. The introduction of new manufacturing processes will likely cause test costs to occupy a higher percentage of the total cost of manufacturing and, therefore, increase price pressure on the test system industry.
Advances in the semiconductor and electronic component industry will also require test systems with new and more sophisticated testing functions. Advantest believes that these trends provide it with an opportunity to distinguish itself from its
competitors through the delivery of new products that are priced and designed to meet the specific needs of its customers.

manufacturers from their product design stage of semiconductor and component test systems to understand customer needs relating to emerging technologies and applications. Based on this knowledge and its technological expertise, Advantest seeks to
develop more advanced semiconductor and component test systems, test handlers, device interfaces and comprehensive solutions ahead of its competitors. For example, Advantest is pursuing the following strategies:



| |  |  | developing semiconductor and component test systems with increased test speeds and throughput capabilities and test handlers in line with the technological development of memory
semiconductors, SoC semiconductors and other semiconductors;

and large pin counts.

Strengthen the test system business for SoC semiconductors



Advantest believes that the market for test systems for SoC semiconductors
in 2004 was over 1.5 times the size of the market for test systems for memory semiconductors. Based on this view, Advantest has devoted its resources to develop test systems for SoC semiconductors to meet the demands of a large number of
manufacturers for the testing of a wide variety of SoC semiconductors.



Advantest continues to promote the adoption of OPENSTAR®, an industry-wide, open architecture for test systems for SoC semiconductors. Advantest believes that the primary benefits of OPENSTAR® for users of semiconductor and component test systems will be reduced testing costs and greater procurement options. In
addition, Advantest hopes that the reduction in testing costs, and thus the lowering of overall manufacturing costs of SoC semiconductors, will help foster further demand for SoC semiconductors to be used in digital consumer products and other
products. Finally, Advantest believes that the adoption of a new open architecture will provide an opportunity for late entrants to the test systems for SoC semiconductors market, such as Advantest, to increase their market share.



Focus sales and support efforts on key customers accounts



Advantest believes that a small number of large semiconductor manufacturers,
test houses and foundries account for a large portion of total sales in the semiconductor and component test system industry. Advantest sells semiconductor and component test systems and mechatronics systems to many of these customers and support
them on a regular basis. Advantest is seeking to expand its business with these high-volume customers and develop new relationships with the remaining potential major customers. Over the past several years, Advantest has opened additional overseas
sales and support offices, many of which are located near the corporate headquarters or main research and development and manufacturing facilities of these high-volume customers. These offices are expected to facilitate Advantests efforts to
continue conducting collaborative development activities with leading semiconductor manufacturers.



Products



As of fiscal
2004, Advantests main products are products developed, manufactured and sold in the semiconductor and component test system segment and mechatronics system segment. They are as follows:



Semiconductor and Component Test Systems Segment

##### Table of Contents

Test systems for memory semiconductors consist of a mainframe and one or more test heads. During testing,
a device interface is attached to the test head. During the front-end testing process, wafers are attached to and detached from the device interface by a prober. Electric signals are transmitted between the die and the test systems for memory
semiconductors through probe pins located in the device interface. After front-end testing is completed, the wafer is diced into separate dies and properly functioning dies are packaged. During back-end testing, test handlers are used to load these
devices onto the device interface, and electric signals are transmitted between the semiconductor chips and the semiconductor test system via the device interface. The results are stored in a database, and then analyzed by the test systems for
memory semiconductors hardware circuits and software programs. Each different semiconductor design requires a customized software program to analyze the test data.



Characteristics of the performance and other characteristics of test systems for memory semiconductors that are important to
customers include:



Throughput. Throughput is measured
by the number of semiconductors that can be tested by test systems for memory semiconductors during a specified time.



Test Speed. Test speed is the speed at which the test systems for memory semiconductors test semiconductors during testing. Test speed is measured
in terms of megahertz, or MHz.



Timing Accuracy. Timing
accuracy is the test system for memory semiconductors accuracy of control over the timing of testing signals generated.



Maximum Pin Count. Maximum pin count is the number of channels for test signals (at the maximum) used by test systems for memory semiconductors.



Size. Smaller machines reduce the amount of floor space
occupied and electricity consumed by the test systems for memory semiconductors.



Temperature. Semiconductor manufacturers perform tests on semiconductors at varying temperatures to ensure proper operation under extreme conditions.



Compatibility. Test systems for memory semiconductors that are
compatible with predecessor systems cut down on the time required to develop new test programs and otherwise allow for effective utilization by customers of existing resources.



Quality. Quality is determined by the reliability of test results produced and whether the equipment can maintain
stable operation under different testing environments.



Advantest estimates that its market share in test systems for memory semiconductors rose from 61.0% in 2003 to 69.5% in 2004. Advantest believes that its overall market share increased in 2004 primarily due to the increase in sales of its
test systems for DRAM semiconductors and flash memory semiconductors. Advantest has a substantially larger market share in back-end test systems for memory semiconductors than in front-end test systems for memory semiconductors. Advantest is
currently seeking to increase its market share in front-end test systems for memory semiconductors.



Advantests top four product lines of test systems for memory semiconductors are the T5580 series, the T5590 series, the T5370 series and the T5700
series.



T5580 Series. The T5585 is one of the most
predominant testers on the market, designed for high-bandwidth DRAM products, such as SDRAM and DDR-SDRAM.



T5590 Series. Advantests newest test systems for memory semiconductors aimed at the high-speed SRAM, DDR-SRAM, DDR2-SDRAM, DDR3-SDRAM, SGRAM
and DRAM semiconductor markets is the T5593.

##### Table of Contents

SRAM, or static random access memory, is a type of memory semiconductor that, unlike DRAM, does not need to be refreshed while the power supply remains.
SGRAM, or synchronous graphics random access memory, is a type of memory semiconductor used for graphics. The T5593 are designed for use in the design and production of super high-speed memory devices and the T5593 can simultaneously measure up to a
maximum of 256 DDR2-SDRAM devices.



T5370 Series. The
T5375 and T5377 are multi-functional test systems for memory semiconductors that reduce testing costs for semiconductor manufacturers. The T5375 and T5377 are used for the front-end testing of DRAM semiconductors and for back-end testing of flash
memory semiconductors. By increasing the functions of the system, Advantest has succeeded in selling to a larger customer base. The T5375 and T5377 can test up to 256 devices at one time. The T5375 and T5377 are aimed at capturing an increased
market share in front-end DRAM semiconductor testing and has double the throughput capabilities of the T5371, the predecessor to the T5375, thereby lowering overall testing costs for its customers. In particular, the T5377 optimizes its memory
repair analytical structure to a users memory repair algorithm and, due to its higher throughput capabilities, is suited for the production of semiconductors in manufacturing facilities that use 300 millimeter wafers. The T5370 series is
Advantests best selling test systems for memory semiconductors product line for front-end testing of DRAM semiconductors and for back-end testing of flash memory semiconductors.



T5700 Series. Flash memory semiconductors require more types of front-end testing than other types of semiconductors.
Advantests latest front-end test system for flash memory semiconductors is the T5724. The T5724 is capable of simultaneously testing up to 2,048 flash memory semiconductors with the Built-in-Self-Test, or BIST, function, which is sixteen times
greater than the capacity of previous models, and significantly lowers test costs. The increase in capacity is due to the T5724s use of a probe card that allows for aggregate wafer contact which increases test speed.



Test Systems for Non Memory Semiconductors



Advantests main line-up of test systems for non memory semiconductors
relates to test systems for SoC semiconductors and other test systems for non memory semiconductors.



Test Systems for SoC Semiconductors



Test systems for SoC semiconductors test semiconductors with specific functions, such as SoC semiconductors that combine analog and/or memory circuits on
a single semiconductor chip and LCD driver integrated circuits that display image on LCD panels. The factors that are important to customers in the performance and other characteristics of test systems for memory semiconductors described above also
apply to test systems for SoC semiconductors. Advantests market share in test systems for SoC semiconductors increased from 11.3% in 2003 to 16.8% in 2004.



T6600 Series. The T6673 is Advantests latest version of its T6600 series. The T6673 is designed to reduce total
test costs associated with the production of SoC semiconductors. The T6673 is designed to test SoC semiconductors incorporated into high-speed communication network equipment and wireless handsets, digital consumer products and other electronic
systems. The T6673 can test semiconductor chips with a maximum pin count of 1,024, thus matching the trend of SoC semiconductors with increasing pin counts. The T6673 is capable of both front- and back-end testing of SoC semiconductors.



T6500 Series. The T6577 test systems for SoC semiconductors in the
T6500 series are primarily designed to test MCU and SoC semiconductors that control digital consumer products at the production lines. The T6500 series is approximately one-third in size, and uses approximately 50% less power, as compared to
Advantests predecessor product line. Further, the T6500 series operates on a software that is compatible with the T6600 series.



T2000. Advantest brought to market a test system for SoC semiconductors that is based on component modules compatible with OPENSTAR® open architecture. Advantest believes that the
development of

OPENSTAR® compatible semiconductor test systems for SoC semiconductors will increase Advantests market share in test systems for SoC semiconductors. Currently, Advantests OPENSTAR® compatible test systems for SoC semiconductors is the
T2000. Main compatible component modules for the T2000 are the 250 MHz Digital Module, the Low Current DPS and the High Current DPS. The 250 MHz Digital Module primarily targets the testing of MPU and operates at a maximum of 666 MHz/IO.



T6300 Series. The T6362 and T6372 are test systems for non memory
semiconductors for semiconductors used with high-definition LCD displays. This system can simultaneously test multiple semiconductors for LCD driver integrated circuits with a total of up to 1,536 pins.



T7720 Series. The T7721 and T7722 are test systems for non
memory semiconductors for mixed signal integrated circuits. The T7721 targets highly complex semiconductors used in car electronics and results from the development of Advantests constituent technology that measures analog signals. The T7721
uses a direct current signal generator with a range of 150V to 64V and utilizes up to a maximum of 256 pins, and the T7721 has the capacity to simultaneously measure multiple devices.



T8571. The T8571 is a test system for non memory semiconductors that is primarily used to evaluate and analyze CCDs
that are image sensors. These semiconductors are used in digital consumer products, such as high-resolution digital cameras, mobile phone handset cameras and digital video cameras.



Mechatronics System Segment



Main products in the mechatronics system segment are test handlers which handle semiconductor devices and automate the
testing, and device interfaces which are the interfaces with devices being tested.



Test Handlers



Test handlers are used with semiconductor and component test systems to handle, thermally condition, contact and sort semiconductors and other electronic components during the back-end testing of the semiconductor manufacturing process.



Advantests test handlers are sold primarily in
conjunction with the sale of its semiconductor and component test systems. During fiscal 2004, a majority of test handlers, measured in units, were sold to customers of Advantests semiconductor and component test systems. Advantests test
handlers are compatible with the semiconductor and component test systems of its competitors.



Test handlers are designed with different characteristics for memory and non memory semiconductors. Memory semiconductors require relatively long test times. Advantests test handler for memory semiconductors
handle up to 128 semiconductors per test head at a time. Non memory semiconductors, including SoC semiconductors, require relatively short test times and Advantests test handlers handle up to eight semiconductors at a time.



Test Handlers for Memory Semiconductors. Advantests test handler
for test systems for memory semiconductors is the M6771AD that handles up to 64 semiconductors at a time. The M6771AD achieves maximum throughput of up to 7,200 semiconductors per hour through the use of a new tray transport mechanism that shortens
the time between tests to approximately half of the time associated with Advantests lower-end model. Semiconductor manufacturers can elect to use two M6771AD test handlers per semiconductor and component test system to double the handling
capacity per semiconductor and component test system. The M6542AD is another test handler for memory semiconductors designed to be used during back-end testing of DDR-SDRAM and other high-speed SDRAM that handles up to 128 semiconductors at a time.
The M6542AD is designed to prevent the generation of excessive heat during simultaneous measuring by employing a newly developed temperature control technology. Advantest also has other test handler product line-up for test systems for memory
semiconductors that meet varying cost and functional needs of its customers.

Test Handlers for NonMemory Semiconductors. Advantests test handlers for test
systems for non memory semiconductors, including SoC semiconductors, are the M4541A and the M4541AD. Both test handlers for non memory semiconductors achieve maximum throughput of up to 6,000 semiconductors per hour. The M4541A can simultaneously
handle up to four devices and the M4541AD can simultaneously handle up to eight devices.



M4741A is a back-end test handler for non memory semiconductors that utilizes vision alignment and can be used for small, narrow pitch semiconductors. The M4741A achieves maximum throughput of up to 4,000
semiconductors per hour. The M4741A can simultaneously handle up to four devices.



M7521A is a test handler that can be used for chip on film, or COF, and tape automated bonding, or TAB of integrated circuit drivers used in flat-panel displays. The M7521A can test devices used in 35 millimeter, 48
millimeter, 70 millimeter, wide and superwide tapes.



Device Interfaces



A device interface
is a mechanism through which test signals are transmitted between the device being tested and a semiconductor and component test system. Well-designed device interfaces that are compatible with various types of devices enhance the utility of a
semiconductor and component test system by allowing it to test different semiconductor product lines and therefore reducing the cost for semiconductor and component test system users.



Advantest manufactures device interfaces for semiconductor and component test systems and is continuously developing and
supplying new device interfaces, such as high performance connectors and socket boards, featuring increased throughput, precision and ease of maintenance to meet the demands of next-generation semiconductors that are becoming more high speed.
Advantest believes that the rate at which new semiconductor designs are introduced to market will continue to increase in the long term, and demands for main parts of device interfaces that are compatible with such new semiconductor designs will
increase accordingly.



Advantest competes with numerous small
and independent electronics manufacturers in providing device interfaces for its semiconductor and component test systems. However, Advantest believes that as the complexity of the testing requirements of next-generation semiconductors increases,
Advantest will enjoy competitive advantages by applying its technical knowledge, such as high speed signal transmission derived from designing and manufacturing semiconductor and component test systems to device interfaces.



Customers



Advantests semiconductor and component test systems and mechatronics systems are shipped and delivered to many of the
worlds leading semiconductor manufacturers, as well as a number of foundries and test houses. Advantests largest customer accounted for approximately 12% in fiscal 2002 and fiscal 2003, and 15% of net sales in fiscal 2004.

Japan.
Advantest believes that its most substantial customer relationships are with Japanese semiconductor manufacturers. Advantest enjoys a significant market position in Japanese markets for test systems for memory semiconductors, with its market share
exceeding 70% in fiscal 2004. In addition, Advantest had approximately a 48% market share in the Japanese test systems for SoC semiconductors market in fiscal 2004. Advantest currently expects sales of test systems for SoC semiconductors used in DVD
recorders and digital televisions and sales of test systems for SoC semiconductors for LCD driver integrated circuits used to display images on LCD panels comprised a substantial portion of total sales of test systems for non memory semiconductors
in Japan in fiscal 2004. Advantest is working to solidify its market leadership in Japan by continuing to work closely with its major customers to identify their needs during the early stages of their product development cycles.



Asia (excluding Japan). Asia is the largest market for
semiconductor and component test systems and mechatronics systems, with semiconductor manufacturers located in Taiwan, Korea, the Peoples Republic of China, and Singapore accounting for a majority of semiconductor production in Asia. Advantest
views its relationships with these companies as critical to its semiconductor and component test system and mechatronics system business. Many Japanese, U.S. and European semiconductor manufacturers have shifted production to Asia, either to
subsidiaries or foundries and test houses. Capital expenditure decisions for subsidiaries are usually made at the companys headquarters. Foundries and test houses, a majority of which are located in Taiwan, often consult with their customers
before investing in semiconductor and component test systems. Therefore, Advantests performance in Asia will also depend on its ability to maintain strong relationships with customers in Japan, the U.S. and Europe. In addition, some of
Advantests customers have partnered with semiconductor manufacturers in Asia and outsourced manufacturing processes, thus shifting net sales to the Asia geographic market. In the communications industry, Advantest believes investment in fiber
optic and wireless networks in Asia, particularly in the Peoples Republic of China, will increase in the long term, although investment levels may remain at their current levels until further recovery in the global economy.



Americas. Advantests marketing efforts in
this region are centered in the U.S., which accounted for approximately 10% of its total sales in fiscal 2004. Advantests market share of semiconductor and component test systems sold in the U.S. was approximately 23% in 2004, up from
approximately 11% in 2003. Semiconductor and component test systems are marketed and sold in the Americas through Advantests subsidiary, Advantest America Inc.



Europe. Sales in Europe constituted approximately 5% of Advantests sales in fiscal 2004.
Advantests market share of semiconductor and component test systems sold in Europe increased to approximately 20% in 2004 from 14% in 2003. Advantests principal European markets are Germany, Italy and France.

Manufacturing and Supplies



Advantests principal manufacturing plants for semiconductor and
component test systems are Menuma Plant located in Saitama prefecture, Japan and Gunma Plant located in Gunma prefecture, Japan. At Menuma Plant, printed circuit boards for eventual use in test systems are manufactured, while Gunma Plant produces
test systems as final products. The production base for mechatronics systems is Ohtone R&D Center located in Saitama prefecture, Japan. These plants are highly automated and testing and production systems within the plant are interconnected by a
sophisticated local area network using advanced data management software. This network allows Advantest factory managers to check on the status of systems under production at any given time.



Advantest uses an enterprise resource planning system that processes new
information on a real time basis and uses sophisticated data management software that converts sales orders into production specifications and manufacturing plans. This system also interconnects Advantests multiple production and warehousing
facilities to its information network. In addition, Advantest has used a supply chain planning system that can perform real time, high speed simulations of both material sourcing needs and production line loads.



Advantest has integrated many production processes in an effort to introduce
a new production system based on the just-in-time production system and to improve upon the existing production system with a view to attaining a shorter production cycle, cost curtailment and reduction of inventories.



Advantest purchases substantially all of its components and parts from
outside suppliers.



The average costs of components and parts
used by Advantest during the last three fiscal years have remained relatively stable. Advantest believes this relative price stability results from the fact that Advantest negotiates the terms of the purchase orders directly with its suppliers and
the fact that the prices of the made-to-order components set forth in the purchase orders are primarily influenced by the technical specifications of the relevant components and parts.



Device interfaces, one of Advantests products in its mechatronics system segment, are manufactured in Japan as well as
overseas, including Germany, Korea, Taiwan and Malaysia in order to reduce the time required for shipment to customers and to curtail manufacturing costs.



Seasonality



As sales levels of semiconductor and component test systems and mechatronics systems are subject, in large part, to sales levels of semiconductors, which
can fluctuate significantly within any year, Advantest does not traditionally experience higher sales during any certain period of the year as compared to other periods of the year. In fiscal 2004, second quarter net sales were higher than first
quarter net sales due to the recovery and an upward adjustment of the semiconductor market. While net sales in the third quarter declined primarily as a result of a downward adjustment, net sales in the fourth quarter were higher than the third
quarter as the market resumed its recovery.

Advantest considers all of its principal manufacturing
facilities and other significant properties to be in good condition and adequate to meet the needs of its operations. Advantest does not maintain internal records of the exact productive capacity and extent of utilization of its manufacturing
facilities. It would require unreasonable effort and expense to determine this information because Advantest alters the volume, quantity and nature of its manufactured products as necessary in response to changes in demand and other market
conditions, and revamps its manufacturing processes to take advantage of technological innovations. However, Advantest believes that its manufacturing facilities are currently operating at utilization levels that are substantially in line with
prevailing market demand for its products.



Advantest believes
that there does not exist any material environmental issues that may affect the companys utilization of its assets.



As of June 1, 2005, Advantest does not have any material plans to construct, expand or improve its facilities.

##### Table of Contents

Overview



Advantest manufactures and sells semiconductor and component test systems and mechatronics-related products such as test handlers and device interfaces.
Advantest also engages in research and development activities and provides maintenance and support services associated with these products.



In conjunction with its business and organizational restructuring, effective April 1, 2004, Advantest reclassified its two previous segments, automated
test equipment and measuring instruments business segment, into three business segments: semiconductor and component test system segment; mechatronics system segment; and services, support and others segment. Description of Advantests three
segments is as follows. The following figures include intercompany transactions between segments.



The semiconductor and component test system segment provides customers with test system products for the semiconductor industry and the electronic parts
industry. Product lines provided by the semiconductor and component test system segment include test systems for memory semiconductors for memory semiconductor devices and test systems for SoC semiconductors for non memory semiconductor devices.
This reportable business segment is the most important segment, with sales accounting for 75.5% of Advantests consolidated net sales for fiscal 2004.



The mechatronics system segment provides product lines such as test handlers, mechatronic-applied products, for handling semiconductor devices and device
interfaces that serve as interfaces with the devices that are measured and operations related to nano-technology products. This business segment accounted for 19.4% of Advantests consolidated net sales for fiscal 2004.



The services, support and others segment consists of comprehensive customer
services provided in connection with the semiconductor and component test systems and mechatronics system segments, support services, equipment lease business and others. This segment accounted for 8.2% of Advantests consolidated net sales for
fiscal 2004.



Semiconductor and Component Test System Segment



The market for semiconductor and component test
systems is highly cyclical and competitive, and depends on the appetite for capital expenditures of customers. Their capital expenditures depend, to a large extent, on:



| |  |  | demand for semiconductors and electronic components;
| | - |  | ----------------------------------------------------



| |  |  | innovation in semiconductor and electronic component technology; and
| | - |  | --------------------------------------------------------------------



| |  |  | changes in semiconductor and electronic component manufacturing processes.
| | - |  | --------------------------------------------------------------------------



During the first half of fiscal 2004, conditions affecting Advantests semiconductor and component test system segment have been generally favorable
due to an increase in capital expenditures in the semiconductor manufacturing industry, as stimulated by the substantial sales of digital consumer products including digital cameras and DVD recorders, decreased volatility of DRAM semiconductor
prices, and improved demand for personal computers. However, with inventory adjustment in the semiconductor manufacturing industry commencing in the second half of fiscal 2004, the demand for semiconductor and component test systems became sluggish.
For a detailed discussion of these factors and their effect on demand for semiconductor and component test systems, see Information on the CompanyBusiness OverviewIndustry Overview.



With respect to the market for test systems for memory semiconductors, net
sales of test systems for flash memory semiconductors for fiscal 2004 increased within and outside Japan. In addition, sales of test systems for DRAM semiconductors experienced increased, particularly with respect to new products such as the
high-speed test systems for memory semiconductors for next generation double data rate, or DDR-SDRAM, in addition to general purpose high-speed memory testers, which attracted substantial purchase inquiries both in Japan and overseas.

##### Table of Contents

In the area of test systems for non memory semiconductors, test systems for SoC semiconductors used in
mobile phones and digital consumer devices and test systems for non memory semiconductors used for LCD driver integrated circuits, maintained sales at high levels from the previous fiscal year, particularly in Japan and Taiwan. In addition,
Advantest introduced new products aimed at the CCD and in-car device market.



As a result of the above, consolidated net sales of the semiconductor and component test system segment increased 46.3% to ¥180,685 million in fiscal 2004, as compared to the previous fiscal year.



In spite of robust growth in the semiconductor market in the second half of
fiscal 2003 through the first half of fiscal 2004, Advantest believes that there exists a significant cyclicality and a continued lack of visibility in the areas of semiconductor demand which is greatly affected by inventory adjustment in the
semiconductor manufacturing industry.



While Advantests
net sales, results of operations and financial conditions in fiscal 2004 were affected by price pressure, results of operations showed significant increase over fiscal 2003. Net sales of test systems for memory semiconductors in fiscal 2004
increased by 41.2% as compared to fiscal 2003, while net sales for test systems for non memory semiconductors increased by 59.0% as compared to fiscal 2003. Advantests best selling test systems for non memory semiconductor test systems in
fiscal 2004 was the T2000, a test system for SoC semiconductors based on OPENSTAR®, an industry-wide, open architecture, and the T6500 series, Advantests relatively lower cost test systems for SoC semiconductors. Demand for these semiconductor and component test systems was driven by expanded
production during 2003 and 2004 of digital consumer electronics that incorporate semiconductors, including wireless handsets, DVD recorders and digital cameras. These semiconductors typically are mass-produced and carry per unit market prices that
are lower than high-end SoC semiconductors and high-bandwidth DRAM semiconductor and SRAM semiconductor products. Therefore, Advantests customers that produce these semiconductors required less expensive semiconductor and component test
systems in order to reduce their overall manufacturing costs.



Advantest believes that demand for its newer products was driven by customers increased levels of capital expenditures towards the improvement of their production capacities, such as through investments relating to 300 millimeter
wafers and to the next generation of memory semiconductor devices. In most cases, the sales prices of semiconductor and component test systems gradually decreases as their commercial life becomes longer.



Advantest believes that price pressure with respect to semiconductor and
component test systems tends to be strongest during periods when demand, in terms of volume, for semiconductors is increasing, but there exists pressure on the market price for semiconductors. Advantest faced significant price pressure in almost all
of its product lines during fiscal 2001 and 2002. In fiscal 2003 and fiscal 2004, price pressure continued to exist. While the semiconductor industry experienced a recovery, increased competition in the market for digital consumer products and
personal computers drove down prices of these goods, subsequently creating significant price pressure on its product lines. Advantest believes that despite this significant price pressure, Advantest was able to increase its competitiveness by
bringing to market new products.



Mechatronics System Segment



In fiscal 2004, Advantests sales in the test
handler business increased substantially, led by the sales of test handlers for memory semiconductors. This increase was driven by Advantests clients increasing production of DDR-SDRAM semiconductors and investments in DDR2-SDRAM
semiconductors, as well as their active investments in flash memory semiconductors. In each case, customers typically demanded test handlers for memory semiconductors capable of simultaneously measuring 128 devices. The growth in demand for the
high-speed test handler for memory semiconductors M6542AD, a test handler equipped with a new cooling function, was especially strong.

##### Table of Contents

Net sales of test handlers for SoC semiconductors also increased in fiscal 2004, with increased sales of
the TAB handler M7521A for LCD integrated circuit drivers designed for fine pitch packages and the M4741A series of test handlers for SoC semiconductors, the latter with vision alignment functions. Demand was enhanced primarily through the strong
performance of digital consumer devices in the market.



Net
sales of device interfaces rose sharply in fiscal 2004 on the back of the increase in the net sales of semiconductor and component test systems. Net sales in Taiwan were particularly strong in fiscal 2004 compared to fiscal 2003 due to active
capital expenditures in DDR2-SDRAM semiconductors. Device interfaces with lower costs for component replacement of measured devices also performed well, and contributed to the increase in net sales. Advantest launched a single-contact wafer probe
card for the BIST as a new product, and believes that the market has generally received it well.



As a result of the above, net sales of the mechatronics system segment increased by 35.6% compared to fiscal 2003 to ¥46,395 million in fiscal 2004.



Services, Support and Others Segment



In the services, support and others segment, Advantest has focused on
maintenance services such as installation and repairs of Advantests products and lease and rental services of its products as a part of Advantests effort to provide customers with comprehensive solutions. Net sales of this segment
decreased by 3.8% compared to fiscal 2003 to ¥19,680 million in fiscal 2004.



Research and Development



Research and
development expenses represent a significant portion of Advantests annual operating expenses. Advantests research and development expenses were ¥23,615 million, ¥21,637 million and ¥26,280, or 24.1%, 12.4% and 11.0% of net
sales, in fiscal 2002, 2003 and 2004, respectively. Advantest plans to continue its substantial investments in research and development and has allocated approximately ¥28 billion for its research and development budget of fiscal 2005. However,
Advantests research and development budget for fiscal 2005 may change based on its business results in fiscal 2005 and future prospects of its business.



Personnel



As of March 31, 2005, Advantest had a total of 3,565 full-time employees, an increase of 21 persons, or 0.6%, over March 31, 2004.



Advantest plans to continue its periodic recruitment of new graduates as part
of its mid- to long-term growth strategy. Advantest expects that a majority of these new hires will join the semiconductor and component test system segment and mechatronics system segment to support the growth of Advantests businesses. Other
new hires are expected to join Advantests maintenance or administrative divisions. The addition of these new hires may increase Advantests future selling, general and administrative expenses and its research and development expenses.



Currency Fluctuations



Advantest is affected to some extent by fluctuations in foreign currency
exchange rates. Advantest is principally exposed to fluctuations in the value of the Japanese yen against the U.S. dollar and other currencies of countries where Advantest does business. Advantests consolidated financial statements, which are
presented in Japanese yen, are affected by foreign currency exchange fluctuations through both translation risk and transaction risk.



Translation risk is the risk that Advantests consolidated financial statements for a particular period or for a particular date will be affected by
changes in the prevailing exchange rates of the currencies in which



34



---

##### Table of Contents

subsidiaries of Advantest prepare their financial statements against the Japanese yen. Even though the fluctuations of currencies against the Japanese yen
can be substantial and, therefore, significantly impact comparisons with prior accounting periods and among various geographic markets, the translation effect is a reporting consideration and does not reflect Advantests underlying results of
operations. Advantest does not hedge against translation risk.



Transaction risk is the risk that the currency structure of Advantests costs and liabilities will deviate from the currency structure of sales proceeds and assets. Advantest produces substantially all of its products, including all
semiconductor and component test systems, in Japan. A small portion of the components and parts used in Advantests semiconductor and component test systems is purchased in currencies other than the yen, predominantly the U.S. dollar.



Advantest enters into foreign exchange forward contracts to
hedge a portion of its transaction risk. This has reduced, but not eliminated, the effects of foreign currency exchange rate fluctuations against the Japanese yen, which in some years can be significant.



Generally, a weakening of the Japanese yen against other currencies,
particularly the U.S. dollar, has a positive effect on Advantests operating income and net income. A strengthening of the Japanese yen against other currencies, particularly the U.S. dollar, has the opposite effect. The Japanese yen generally
strengthened against the U.S. dollar throughout fiscal 2004 and fiscal 2003, when compared to fiscal 2002.



Advantests business is subject to risks associated with doing business internationally, and its business could be impacted by certain governmental,
economic, fiscal, monetary or political policies or factors, including trade protection measures and import or export licensing requirements, that may materially affect, directly or indirectly, Advantests operations or its future results.



Critical Accounting Policies and Estimates



Advantest has made a number of estimates and assumptions relating to the
reporting of assets and liabilities and the disclosure of contingent assets and liabilities in preparing its consolidated financial statements in conformity with U.S. GAAP. Critical accounting policies are accounting policies that require the
application of managements most difficult, subjective or complex judgments and often require management to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods. The following is not
intended to be a comprehensive list of all of Advantests accounting policies. Advantests significant accounting policies are more fully described in note 1 to Advantests consolidated financial statements included elsewhere in this
annual report. In many cases, U.S. GAAP specifically dictates the accounting treatment of a particular transaction, with no need for judgment in its application. There are also areas in which managements judgment in selecting an available
alternative would not produce materially different results. Set forth below is a description of accounting policies under U.S. GAAP that Advantest has identified as critical to understanding its business and the reported financial results and
condition of the company.



Revenue Recognition



In accordance with the guidance provided by the Securities and Exchange
Commissions Staff Accounting Bulletin No. 104, Revenue Recognition, Advantest recognizes revenue when there is persuasive evidence of an arrangement, title and risk of loss have passed, delivery has occurred or the services have
been rendered, the sales price is fixed or determinable and collection of the related receivable is reasonably assured.



Revenue from Sales of Products



Revenue from sales of products which require installation work is recognized when the related installation work is completed. The revenue recognized upon
completion of installation is limited to the amount that is



35

##### Table of Contents

payable based on customer acceptance. Revenue from sales of products and component which do not require installation work by Advantest is recognized upon
shipment if the terms of the sale are free on board (FOB) shipping point or upon delivery if the terms are FOB destination which coincide with the passage of title and risk of loss.



For equipment sales involving software that is more than incidental to the
product, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collection of the related receivable is probable in accordance with American Institute of
Certified Public Accountant (AICPA) Statement of Position (SOP) No. 97-2, Software Revenue Recognition, as amended by SOP No. 98-9, Modification of SOP 97-2, Software Revenue Recognition, With Respect to
Certain Transactions. Revenue for the separate elements is only recognized when the functionality of the undelivered element is not essential to the delivered element.



Revenue from Long-term Service contracts



Revenue from fixed-price, long-term service contracts is recognized on the straight-line basis over the contract term.



Operating lease



Revenue from operating leases is primarily recognized on the straight-line
basis over the lease term.



Multiple deliverables



Multiple Deliverables are accounted for under the
Emerging Issues Task Force Issue No. 00-21 (EITF 00-21), Revenue Arrangements with Multiple Deliverables. EITF 00-21 addresses how to determine whether an arrangement involving multiple deliverables contains more than one
unit of accounting.



Advantest enters into certain revenue
arrangements with multiple deliverables, which include combination of equipment, installation and warranty services. As those installation or warranty services are not interchangeable to be provided by Advantest or other parties and as fair values
of those services are not determinable, these elements are not considered to qualify for separate accounting under EITF 00-21 and accordingly Advantest treats them as a single unit of accounting. Advantest adopted the provisions of EITF 00-21 for
the transactions entered into on and after July 1, 2003. The effect on Advantests consolidated financial statements from the adoption of such provisions was insignificant.



Inventories



Advantests inventories consist of on-hand inventory, including inventory located at customer sites, and inventory that is on-order and subject to a
contract that is non-cancelable. Advantest states its inventories at the lower of cost or market. Cost is determined using the average cost method. Advantest determines the market for finished goods by determining net realizable value and for raw
materials by identifying replacement cost. Advantest reviews its inventories and determines the appropriate amount of any inventory write-downs periodically based on these reviews. Write-downs occur from the discontinuation of product lines,
inventory in excess of estimated usage, the release of new products which renders inventory obsolete and declines in net realizable value of Advantests inventory leased to customers. Advantest recognizes inventory write-downs in cost of sales.



Advantests inventories decreased by ¥19,838 million,
or 40.1%, during fiscal 2004 to ¥29,585 million as of March 31, 2005. Advantest recorded inventory write-downs in the amount of ¥855 million in fiscal 2004 and write-downs of ¥2,126 million in fiscal 2003. Advantest may be required to
take additional charges for excess

and obsolete inventory in fiscal 2005 or other future periods if future weakness in its businesses causes further reductions to Advantests inventory
valuations. In addition, unexpected changes in testing technology can render Advantests inventories obsolete. Advantest evaluates its inventory levels based on its estimates and forecasts of demand for its products.



Trade Receivables



Advantests trade receivables, less allowance for doubtful accounts was
¥56,702 million as of March 31, 2005, down from ¥76,133 million as of March 31, 2004. Advantest maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments.
Advantest provides an allowance for doubtful accounts for all specific accounts receivable that it judges are probable of not being collected. Advantest has not recorded any allowances for trade receivables for its major customers, a majority of
which are large, well-capitalized semiconductor manufacturers, test houses and foundries. Advantest receives deposits from most of its distributors for its other test systems. Advantest believes that the amounts of these deposits are sufficient to
offset the amounts of any possible defaults on accounts receivable of these customers.



Advantest periodically reviews its estimated allowances for doubtful accounts taking into account the customers payment history, assessing the customers current financial position and considering other
information that is publicly available and the customers credit worthiness. Additional reviews are undertaken upon significant changes in the financial condition of Advantests significant customers and the semiconductor industry.



While the semiconductor market experienced a recovery in
fiscal 2004, certain Advantest customers continued to improve their cash flows that impacted their ability to make required payments. At the end of fiscal 2004, Advantest decreased its allowance for doubtful accounts by ¥290 million to
¥2,174 million. The provision is charged to selling, general and administrative expenses. While conditions in the industries of some of Advantests customers are expected to improve in fiscal 2005, additional allowances may be necessary if
conditions in the industries of some of Advantests customers do not improve in the near-term. Conversely, a reversal of allowances made for accounts receivable that are later collected, depending upon the recovered financial status of its
customers and Advantests collection efforts, will decrease the selling, general and administrative expenses for the accounting period during which such collection takes place.



Accrued Warranty Expenses



Advantests products are generally subject to a 12-month free repair warranty. In addition, under certain circumstances, Advantest is responsible for
the repair of defective components and parts. Advantest provides an allowance for estimated product warranty expenses when product revenue is recognized as part of its selling, general and administrative expenses. The allowance for estimated product
warranty expenses represents managements best estimate at the time of sale of the total costs that Advantest will incur to repair or replace components or parts that fail while still under warranty. Advantest records its allowance for
estimated product warranty expenses based on the historical ratio of actual repair and support expenses to corresponding sales. The foregoing evaluations are inherently uncertain as they require estimates as to maintenance costs and failure rates
related to different product lines. Consequently, actual warranty costs may differ from the estimated amounts and could result in additional product warranty expenses. If actual warranty costs significantly exceed the amount of Advantests
allowance for product warranty expenses, it would negatively affect the future results of operations of Advantest. Accrued warranty expenses were ¥4,090 million in fiscal 2004, up from ¥3,121 million in fiscal 2003.



Stock-Based Compensation



Prior to April 1, 2004, Advantest Corporation accounted for stock-based
compensation plans by applying the intrinsic value-based method of accounting under the recognition and measurement provisions of APB

##### Table of Contents

Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations, as permitted by SFAS No. 123, Accounting for
Stock-Based Compensation. No stock-based employee compensation cost was recognized in the statement of operations until the year ended March 31, 2004. Effective April 1, 2004, Advantest Corporation early adopted the fair value recognition
provisions of SFAS No. 123 (revised 2004) (SFAS No. 123R), Share Based Payment, using the modified-retrospective method. The value of the options is estimated using a Black Scholes option pricing model and amortized to
expense over the options vesting periods. Stock based compensation expense of ¥2,290 million was included reported net income for the year ended March 31, 2005.



Accrued Pension and Severance Cost



Advantest Corporation and certain of its domestic subsidiaries have retirement and severance defined benefit plans covering substantially all of their
employees. The benefits are based on years of service and the employees compensation and vest after one year of service. Prior service cost that results from amendments to the plan is amortized over the average remaining service period of the
employees expected to receive benefits. Unrecognized net gain and loss is also amortized over the average remaining service period of the employees expected to receive benefits.



On October 1, 2004, Advantest Corporation and certain of its domestic subsidiaries received approval from the Minister of
Health and Labor to return the substitutional portion of its Employees Pension Fund plans for the prior employees services under the transfer of its Employees Pension Fund plans to the defined benefit corporate pension plan, and
made the payment of the amount pertinent to the return (minimum liability reserve) to the national treasury on February 24, 2005. Advantest accounted for the elimination of future benefits and relief of past obligations with the transfer of assets
as the culmination of a series of steps in a single settlement transaction and recognized a net gain of ¥3,317 million through these transactions for the year ended March 31, 2005, which is included in selling, general and administrative
expenses and consists of ¥6,116 million of a subsidy from the government, calculated as the difference between the obligation settled and the plan assets transferred to the government, and ¥2,799 million of a settlement loss on recognition
of related unrecognized actuarial loss. See Note 17 to the consolidated financial statements for further discussion.



Deferred Tax Assets



In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred
tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled
reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. At March 31, 2004, Advantest has recorded on its consolidated balance sheet, net deferred tax assets of ¥33,323 million
of which ¥13,079 million represents net operating losses, or NOL, carried forward available to offset future taxable income. Net operating loss carryforwards utilized during the years ended March 31, 2003, 2004 and 2005 were ¥633 million,
¥24,510 million and ¥31,132 million, respectively. At March 31, 2005, Advantest has recorded on its consolidated balance sheet, net deferred tax assets of ¥21,572 million of which ¥444 million represents NOL. Based upon projections
for future taxable income over the periods in which the deferred tax assets are deductible including managements expectations of future semiconductor and semiconductor and component test systems market prospects and other factors, management
believes it is more likely than not that Advantest will realize the benefits of these deductible differences, net of the existing valuation allowance, at March 31, 2005.



Results of OperationsFiscal 2004 Compared with Fiscal 2003



Net Sales



Advantests net sales increased by ¥65,221 million, or 37.4%, compared with fiscal 2003, to ¥239,439 million in fiscal 2004. This increase
was primarily due to an increase in its sales of test systems for memory semiconductors

for DRAM semiconductors and flash memory semiconductors in the semiconductor and component test system segment as well as test systems for SoC semiconductors
for MPUs, and the strong sales, mainly for the first half of fiscal 2004, of test systems for SoC semiconductors for consumer digital devices and test systems for non memory semiconductors used for LCD driver integrated circuits. Strong sales in the
mechatronics system segment led by the performance of memory testers also contributed to this increase. The estimated effect of changes in exchange rates during fiscal 2004 was to decrease Advantests net sales by ¥3,105 million.



The following is a discussion of net sales for
Advantests semiconductor and component test system and mechatronics system segments. Net sales amounts discussed include intercompany sales between segments.



Semiconductor and Component Test System Segment



In fiscal 2004, net sales of Advantests semiconductor and component test system segment accounted for 75.5% of total
net sales. Net sales of Advantests semiconductor and component test system segment increased by ¥57,196 million, or 46.3%, compared with fiscal 2003, to ¥180,685 million in fiscal 2004. Advantests net sales in this segment in the
second half of fiscal 2004 were ¥67,513 million, resulting in a decrease by ¥45,659 million, or 40.3%, compared to the first half of fiscal 2004. This slowdown in the second half of fiscal 2004 reflects reduced customer demand resulting from
inventory adjustments. The estimated effect of changes in exchange rates during fiscal 2004 was to decrease Advantests net sales from its semiconductor and component test system segment by ¥2,431 million.



Net sales of test systems for memory semiconductors increased by ¥36,117
million, or 41.2%, compared with fiscal 2003 to ¥123,856 million in fiscal 2004. This increase was mainly due to increased orders, both in Japan and overseas, for new products such as the T5593, a test system for super high-speed memory
semiconductors for the next generation DDR-SDRAMs and the T5370 series general purpose test systems for high-speed memory semiconductors, despite the inventory adjustment on the part of our clients in DRAM semiconductor test system in the late first
half of fiscal 2004. The flash memory testers attained strong sales though the middle of the first half of fiscal 2004, continuing the trend from fiscal 2003; however sales were adversely affected by semiconductor manufactures restraining their
capital expenditures amidst inventory adjustment for IT-related products beginning in the second half of fiscal 2004. Advantests sales of test systems for memory semiconductors performed well throughout fiscal 2004, although the increased
sales of test systems for memory semiconductors were partially offset by the adverse effects of sales mix and price pressure. For a discussion of sales mix and price pressure, see OverviewSemiconductor and Component Test System
Segment.



Net sales of test systems for non memory
semiconductors increased by ¥21,079 million, or 59.0%, compared with fiscal 2003 to ¥56,829 million in fiscal 2004. This increase was mainly due to a significant increase in sales of testers in Japan, Korea and Taiwan. Net sales of the T6300
series test systems for non memory semiconductors used for LCD driver integrated circuits and the T6500 series test systems for SoC semiconductors used in mobile phones and digital consumer products increased mainly for the first half of fiscal
2004. In addition, the new concept T2000 series test systems for SoC semiconductors, based on OPENSTAR®, performed well in the U.S. and other countries throughout fiscal 2004. In fiscal 2004, Advantest introduced new products for CCD and in-car device markets.



Mechatronics System Segment



Net sales of mechatronics system segment such as test handlers and device
interfaces increased by ¥12,170 million, or 35.6%, compared to fiscal 2003 to ¥46,395 million in fiscal 2004, reflecting increased sales of semiconductor and component test systems generating an increased need for test handlers and device
interfaces.



This increase was mainly reflecting the strong
sales of test handlers for memory semiconductors with functions such as cooling and simultaneous handling of multiple devices, despite inventory adjustments by Advantests customers in the second half of fiscal 2004. In addition, sales of
device interface products remained strong over fiscal 2004 as a result of diversification of Advantests devices generating increased demand.

Services, Support and Others Segment



Net sales of the services, support and others segment decreased by ¥785
million to ¥19,680 million in fiscal 2004, compared to ¥20,465 million in fiscal 2003. Main businesses in the services, support and others segment for fiscal 2004 focused on, and performed well in, maintenance services, and leases and
rentals. However, as net sales of other products recognized in the fiscal 2003 declined significantly, overall net sales of services, support and others segment decreased in fiscal 2004.



Geographic Markets



Advantest experienced an increase of its net sales in fiscal 2004 in each of its geographic markets, with sales in Asia (excluding Japan) experiencing
the largest increase.



Net sales in Asia (excluding Japan)
increased by ¥54,557 million, or 60.9%, compared to fiscal 2003 to ¥144,120 million in fiscal 2004. Net sales in Taiwan increased by ¥19,955 million, an increase of 62.7% compared to fiscal 2003. Net sales in Korea increased by
¥11,154 million, or 39.0%, compared to fiscal 2003. Net sales in China and the rest of Asia (excluding Japan, Taiwan and Korea) increased by ¥23,449 million, or 80.5%, compared to fiscal 2003. These increases were primarily due to increased
sales of test systems for DRAM semiconductors and flash memory semiconductors to foundries in Taiwan as well as to major semiconductor manufacturers in Korea. The increase in the sales of test systems for SoC semiconductors for MPUs contributed
greatly to the increased sales in China and the rest of Asia (excluding Japan, Taiwan and Korea). The estimated effect of changes in exchange rates during fiscal 2004 was to decrease Advantests net sales from sales in Asia by ¥2,291
million.



Net sales in the Americas increased by ¥6,760
million, or 41.6%, compared to fiscal 2003 to ¥23,024 million in fiscal 2004. These increases were primarily due to increased sales of test systems for memory semiconductors and test systems for non memory semiconductors, which was led by
increased capital expenditures by major U.S. semiconductor makers. The estimated effect of changes in exchange rates during fiscal 2004 was to decrease Advantests net sales in the Americas by approximately ¥896 million.



Net sales in Japan increased by ¥2,035 million, or 3.5%, compared to
fiscal 2003 to ¥60,025 million in fiscal 2004. This slight increase was due to increased sales, primarily for the first half of fiscal 2004, of test systems for non memory semiconductors, particularly the sales of test systems for non memory
semiconductors used for LCD driver integrated circuits, mobile phones and digital consumer devices, and test systems for flash memory semiconductors and DRAM.



Net sales in Europe increased by ¥1,869 million, or 18.0%, compared to fiscal 2003 to ¥12,270 million in fiscal 2004. The sales of test systems
for DRAM semiconductors and test handlers for SoC semiconductors contributed to the increased sales in Europe. The small increase in sales in Europe, compared to areas other than Japan, was primarily because sales in Europe have been shifting to
Asia due to increased outsourcing of manufacturing processes in Asia by Advantests customers in the test systems for memory semiconductors market. Due to the depreciation of the yen in comparison to the Euro, the estimated effect of changes in
exchange rates during fiscal 2004 was to increase Advantests net sales from sales in Europe by approximately ¥82 million.



As a result of increased sales in each of Advantests geographic markets especially outside of Japan, its overseas sales as a percentage of total
sales increased to 74.9% in fiscal 2004 from 66.7% in fiscal 2003.



Operating Expenses



Advantests
operating expenses increased by ¥35,462 million, or 24.8%, compared with fiscal 2003 to ¥178,720 million in fiscal 2004.



Cost of sales increased by ¥30,481 million, or 35.6%, compared to fiscal 2003 to ¥115,994 million in fiscal 2004. While this increase can be
attributed to the increase in net sales from fiscal 2003 to fiscal 2004, such increase

was offset by a decrease of ¥1,271 million in write-downs of inventories compared with fiscal 2003 as well as the improved sales cost ratio attained by
product mix and revenue increase effect amidst the ongoing price pressure.



Research and development expenses increased by ¥4,643 million, or 21.5%, when compared to fiscal 2003, to ¥26,280 million in fiscal 2004. This increase in research and development was focused on the
development of products for the future as well as to increased expenses for research and development subcontractor.



Selling, general and administrative expenses increased by ¥338 million, or 0.9%, compared to fiscal 2003 to ¥36,446 million in fiscal 2004. This
increase consists primarily of the increase of ¥1,227 million in accrued warranty expenses and the increase of ¥2,833 million in variable expenses. In addition, Advantest recognized expenses for stock options for fiscal 2004 in the amount of
¥2,290 million, and the expenses increased by ¥2,018 million due to expenses related to Advantests 50th anniversary events. On the other hand, this increase in selling, general and administrative expenses was offset by various factors.
First, Advantest did not recognize any impairment of long-lived assets in fiscal 2004, as it did in fiscal 2003 in the amount of ¥3,030 million. Second, due to improved collection activities, some allowance for doubtful accounts were reversed,
resulting in a decrease of ¥1,682 million in bad debt expenses, compared to fiscal 2003. Third, Advantest accounted for ¥3,317 million as a decrease in its selling expenses due to the transfer of the substitutional portion of its
Employees Pension Fund plan to the Japanese government and the resulting transition by Advantest to its defined benefit plans.



Operating Income



Operating income increased by ¥29,759 million, compared to ¥30,960 million in fiscal 2003, to ¥60,719 million in fiscal 2004.



Other Income and Expenses



Interest and dividend income increase by ¥258 million, or 76.1%,
compared with fiscal 2003 to ¥597 million in fiscal 2004. This increase was primarily due to the increase in the outstanding balance of deposits and the increase in the interest income.



Interest expense decreased by ¥28 million, or 6.0% when compared to
fiscal 2003, to ¥441 million in fiscal 2004. This decrease was primarily due to lower interest rate payments as a result of repayment of bonds in the amount of ¥4,500 million during fiscal 2004 and a lower average balance of total debt
outstanding during fiscal 2004 compared to fiscal 2003.



Other
income improved by ¥2,885 million, compared to fiscal 2003 to ¥933 million in fiscal 2004. Improvement in the non-operating income was mainly due to the impairment loss on securities decreasing by ¥1,307 million, compared to fiscal 2003,
to ¥122 million in fiscal 2004, and the gains on the sales of investment securities increasing by ¥729 million over fiscal 2003 to ¥943 million in fiscal 2004. Foreign exchange gains and losses represent an improvement of ¥109
million to a loss of ¥77 million in fiscal 2004 compared to the loss of ¥186 million registered in fiscal 2003. This represents the difference between the value of foreign currency-denominated sales translated at prevailing exchange rates
and either (i) the value of sales amounts settled during the year, including those settled using foreign exchange forward contracts, or (ii) the value of accounts receivable and payables outstanding remeasured at the exchange rate in effect at March
31, 2005. In fiscal 2004, foreign exchange gains and losses were negatively impacted due to strengthening of the yen against the U.S. dollar.



Income Taxes



Advantests effective tax rate was 40.0% in fiscal 2003 and 38.4% in fiscal 2004. Advantests statutory tax rate was 40.0% for fiscal 2004. The
difference between the statutory tax rate of 40.0% in fiscal 2004 and the effective tax rate of 38.4% in fiscal 2004 was primarily due to earnings of foreign subsidiaries taxed at different rates from the statutory rate in Japan. For a more detailed
discussion of income taxes of Advantest in fiscal 2004 and fiscal 2003, see note 14 to Advantests consolidated financial statements.

Net Income



Advantests net income increased by ¥20,749 million, or 119.7% compared to fiscal 2003, resulting in a net income of ¥38,078 million in
fiscal 2004. The changes in net income for fiscal 2004 compared to fiscal 2003 reflect the factors discussed above.



Other Comprehensive Income (Loss)



Advantests other comprehensive income improved by ¥7,189 million, compared to fiscal 2003 to ¥3,183 million in fiscal 2004. One of the
reasons for this improvement was a ¥5,611 million increase in foreign currency translation adjustment from a loss of ¥3,976 million in fiscal 2003 to an income of ¥1,635 million in fiscal 2004 as the yen was weaker against euro.
Furthermore, another reason was ¥2,792 million decrease for additional minimum pensions liabilities because of the elimination of the unfunded accumulated benefit obligations in fiscal 2004. However, other comprehensive income was offset by
decrease of an unrealized holding gain on investment of ¥1,214 million.



Results of OperationsFiscal 2003 Compared with Fiscal 2002



Net Sales



Advantests net sales
increased by ¥76,478 million, or 78.2%, compared with fiscal 2002, to ¥174,218 million in fiscal 2003. This increase was primarily due to an increase of net sales in the semiconductor and component test system segment, due to an increase in
capital expenditures in the semiconductor manufacturing industry, as stimulated by the substantial sales of digital consumer products including digital cameras, DVD recorders and digital televisions, decreased volatility of DRAM semiconductor
prices, and improved demand for personal computers. The estimated effect of changes in exchange rates during fiscal 2003 was to decrease Advantests net sales by ¥3,500 million.



The following is a discussion of net sales for Advantests semiconductor and component test system, mechatronics system
and services, support and others segments. Net sales amounts discussed include intercompany sales between segments.



Semiconductor and Component Test System Segment



In fiscal 2003, net sales of Advantests semiconductor and component test system segment accounted for 70.9% of total net sales. Net sales of
Advantests semiconductor and component test system segment increased by ¥59,121 million, or 91.8%, compared with fiscal 2002, to ¥123,489 million in fiscal 2003. Advantests net sales in this segment in the second half of fiscal
2003 were ¥82,528 million, resulting in an increase by ¥41,567 million, or 101.5%, compared to the first half of fiscal 2003. The estimated effect of changes in exchange rates during fiscal 2003 was to decrease Advantests net sales
from its semiconductor test system business by ¥2,500 million.



Net sales of test systems for memory semiconductors increased by ¥48,389 million, or 123.0%, compared with fiscal 2002 to ¥87,739 million in fiscal 2003. This increase was mainly due to increased sales of Advantests test
systems for flash memory semiconductors and DRAM semiconductors. In particular, orders for the T5377, a general purpose test system for high-speed memory semiconductors and the T5593, a test system for super high-speed memory semiconductors for the
next generation DDRs were strong, both in Japan and overseas. The increased sales of test systems for memory semiconductors were partially offset by the adverse effects of sales mix and price pressure. For a discussion of sales mix and price
pressure, see OverviewSemiconductor and Component Test System Segment. Advantests estimated market share for test systems for memory semiconductors increased to 61.0% for fiscal 2003 from 51.9% in fiscal 2002. Advantest
believes that the launch of new lines of flash memory semiconductors which were quite competitive, the shortened time for delivery of products, and the maintenance of a strong market share for back-end test systems for memory semiconductors
contributed to the increase in the market share in fiscal 2003. Advantest maintains a larger market share for back-end test systems for memory semiconductors than that for front-end test systems.

##### Table of Contents

Net sales of test systems for non memory semiconductors increased by ¥10,732 million, or 42.9%,
compared with fiscal 2002 to ¥35,750 million in fiscal 2003. This increase was mainly due to a significant increase in sales in Japan, Korea and Taiwan. Increased net sales of the T6300 series designed to inspect LCD driver integrated circuits
and the T6500 series test systems designed to inspect SoC semiconductors used in mobile phones and digital consumer products contributed to the increase of net sales of test systems for non memory semiconductors. Advantest introduced new products
for CCDs and devices for vehicle equipment. For a discussion of sales mix and price pressure, see OverviewSemiconductor and Component Test System Segment Advantests market share for test systems for SoC semiconductors
increased to 11.3% in fiscal 2003 from 9.3% in 2002 thanks to the increase in sales of test systems for non memory (including SoC) semiconductors.



Mechatronics System Segment



Net sales of mechatronics system segment such as test handlers and device interfaces increased by ¥14,760 million, or 75.8%, compared to fiscal 2002
to ¥34,225 million in fiscal 2003, reflecting increased sales of semiconductor and component test systems generating an increased need for test handlers and device interfaces.



Services, Support and Others Segment



Net sales of the services, support and others segment increased by ¥1,238 million or 6.4%, compared to fiscal 2002 to
¥20,465 million in fiscal 2003. Main businesses in the services, support and others segment were maintenance services, and leases and rentals, which performed well in fiscal 2003.



Geographic Markets



Advantest experienced an increase of its net sales in each of its geographic markets, with sales in Asia (excluding Japan) recording the largest
increase.



Net sales in Asia (excluding Japan) increased by
¥48,302 million, or 117.1%, compared to fiscal 2002 to ¥89,563 million in fiscal 2003. Net sales in Taiwan increased by ¥18,214 million, an increase of 133.9% compared to fiscal 2002. Net sales in Korea increased by ¥15,293 million,
or 114.8%, compared to fiscal 2002. Net sales in China and the rest of Asia (excluding Japan, Taiwan and Korea) increased by ¥14,795 million, or 103.2%, compared to fiscal 2002. This increase was primarily due to increased sales of test systems
for semiconductors to foundries and test houses in Taiwan, the increase of sales of test systems for memory semiconductors to the two major semiconductors manufacturers in Korea as well as the increase in the sales of test systems for semiconductors
in China and the rest of Asia (excluding Japan, Taiwan and Korea). The estimated effect of changes in exchange rates during fiscal 2003 was to decrease Advantests net sales in Asia by ¥3,200 million.



Net sales in the Americas increased by ¥7,598 million, or 87.7%, compared
to fiscal 2002 to ¥16,264 million in fiscal 2003. This increase was primarily due to increased sales of test systems for non memory semiconductors and test systems for memory semiconductors in the U.S., which reflected the increased capital
expenditures by semiconductor makers. The estimated effect of changes in exchange rates during fiscal 2003 was to decrease Advantests net sales in the Americas by approximately ¥1,100 million.



Net sales in Japan increased by ¥19,117 million, or 49.2%, compared to
fiscal 2002 to ¥57,990 million in fiscal 2003. This increase was due to increased sales for test systems for non memory semiconductors, in particular test systems for LCD driver integrated circuits as well as the increase in sales of test
systems for flash memory semiconductors and for DRAM semiconductors. This increase was partially offset by the decrease in sales of measuring instruments for wireless communications reflecting the completion of the initial installation of
third-generation wireless networks in Japan.



Net sales in
Europe increased by ¥1,461 million, or 16.3%, compared to fiscal 2002 to ¥10,401 million in fiscal 2003. The smaller increase rate in sales in Europe, compared to areas other than Japan, was primarily

##### Table of Contents

because sales for test systems for memory semiconductors have been shifting to Asia due to increased outsourcing of manufacturing processes in Asia by
Advantests customers in the test systems for memory semiconductors market. Due to the depreciation of the yen in comparison to the Euro, the estimated effect of changes in exchange rates during fiscal 2003 was to increase Advantests net
sales in Europe by approximately ¥800 million.



Operating Expenses



Advantests operating expenses increased by
¥28,775 million, or 25.1%, compared with fiscal 2002 to ¥143,258 million in fiscal 2003.



Cost of sales increased by ¥28,962 million, or 51.2%, compared to fiscal 2002 to ¥85,513 million in fiscal 2003. This increase was attributable to
the increase of ¥76,478 million in net sales. The ratio of cost to sales in fiscal 2003 improved by 8.8% compared with fiscal 2002. Advantest believes that such improvement was primarily attained due to the decrease of the average cost of parts
(the largest component of the cost of sales) by approximately 10%, the reduction in the number of employees over the preceding two years, the integration of certain subsidiaries, and enhanced production efficiency. However, the effects of these
efforts and initiatives were partially offset by the adverse effects of sales mix and price pressures. For a discussion of sales mix and price pressure, see OverviewSemiconductor and Component Test System Segment.



Research and development expenses decreased by ¥1,978 million, or
8.4%, when compared to fiscal 2002, to ¥21,637 million in fiscal 2003. This decrease in research and development reflected the reduction in the number of employees, decrease in payments for outsourcing of studies and research to external
research institutes as well as a stronger focus on a few number of research and development themes.



Selling, general and administrative expenses increased by ¥1,791 million, or 5.2%, compared to fiscal 2002 to ¥36,108 million in fiscal 2003. This
increase consisted primarily of the increase of ¥1,793 million in accrued warranty expenses, as compared to fiscal 2002. The increase in the accrued warranty expenses was primarily attributable to a large increase in net sales in fiscal 2003.
Conversely, the rate of warranty claims in fiscal 2002 was lower than the average of past years and as a result, the accrued warranty expenses to be recognized for covering the net sales in fiscal 2002 were smaller.



Selling, general and administrative expenses included the aggregate
impairment loss of ¥3,030 million as Advantest applied accounting for impairment of fixed assets to long-lived assets which fall within the asset group category of measuring instruments. Advantests selling, general and administrative
expenses also increased compared with fiscal 2002 as Advantest provided additional allowances for doubtful accounts of ¥1,402 million for some external customers in Asia. However, this increase was offset by the non-incurrence in fiscal 2003 of
¥4,090 million, which was incurred in fiscal 2002 as expenses for structural reform initiatives, including additional retirement allowances for employees who applied for early retirement.



Operating Income (Loss)



Operating income increased by ¥47,703 million, compared to operating
loss of ¥16,743 million in fiscal 2002, to an operating income of ¥30,960 million in fiscal 2003.



Other Income (Loss) and Expenses



Interest and dividend income decreased by ¥68 million, or 16.7%, compared with fiscal 2002 to ¥339 million in fiscal 2003. This decrease was primarily due to the decrease in the interest income caused by
falling interest rates in Japan.



Interest expense decreased by
¥21 million, or 4.3% when compared to fiscal 2002, to ¥469 million in fiscal 2003. This decrease was primarily due to lower interest rate payments as a result of repayment of bonds during fiscal 2003 in the amount of ¥2,200 million and a
lower average balance of total long-term debt outstanding during fiscal 2003 compared to fiscal 2002.

Other loss increased by ¥90 million, or 4.8%, compared to fiscal 2002 to ¥1,952 million in fiscal
2003. Increase in the non-operating loss was mainly due to the changes in foreign exchange gains and losses by ¥366 million compared to fiscal 2002, which resulted in an exchange loss of ¥186 million in fiscal 2003. Foreign exchange gains
and losses represent the difference between the value of foreign currency-denominated sales translated at prevailing exchange rates and either (i) the value of sales amounts settled during the year, including those settled using foreign exchange
forward contracts, or (ii) the value of accounts receivable and payables outstanding remeasured at the exchange rate in effect at March 31, 2004. In fiscal 2003, foreign exchange gains and losses were negatively impacted due to strengthening of the
yen against the U.S. dollar. However, Advantests non-operating loss was offset by the decrease in the other-than-temporary declines in fair value of investment securities from ¥1,747 million in fiscal 2002 to ¥1,429 million in fiscal
2003.



Income Taxes



Advantests effective tax rate was 40.0% in fiscal 2003.
Advantests effective tax rate for fiscal 2002 was 30.5%. Advantests statutory tax rate was 42.0% for fiscal 2003. The difference between the statutory tax rate of 42.0% and the effective tax rate of 40.0% in fiscal 2003 was primarily due
to earnings of foreign subsidiaries taxed at different rates from the statutory rate in Japan. For a more detailed discussion of income taxes of Advantest in fiscal 2003 and fiscal 2002, see note 14 to Advantests consolidated financial
statements.



Net Income (Loss)



Advantests net income (loss) increased by ¥30,323 million compared
to fiscal 2002, resulting in a net income of ¥17,329 million in fiscal 2003. The changes in net income for fiscal 2003 compared to fiscal 2002 reflect the factors discussed above.



Other Comprehensive Income (Loss)



Advantests other comprehensive loss increased by ¥1,135 million, or 39.5%, compared to fiscal 2002 to ¥4,006 million in fiscal 2003. One of
the reasons for this increase of loss was a ¥1,061 million increase in foreign currency translation adjustment from a loss of ¥2,915 million in fiscal 2002 to a loss of ¥3,976 million in fiscal 2003. Furthermore, Advantest recognized
minimum pension liabilities of ¥1,396 million because of the incurrence of unfounded accumulated benefit obligations as it changed the discount rate from 2.5% to 2.0% for the purpose of pension accounting. However other comprehensive losses were
partially offset by the gains of ¥1,366 million on the investment securities market because of the rally in the equity market in Japan.



|5.B | LIQUIDITY AND CAPITAL RESOURCES
|--- | -------------------------------



Net cash provided by operating activities was ¥90,327 million in fiscal 2004, compared to ¥28,215 million in fiscal 2003. Net cash provided by
operating activities increased in fiscal 2004 primarily due to the increase in net income to ¥38,078 million, the decrease in trade receivables by ¥20,953 million, the decrease by ¥20,218 million in inventories, and increases in non-cash
expenses, including a charge for deferred income tax of ¥13,540 million and depreciation and amortization of ¥8,285 million, partially offset by the decrease in trade account payables by ¥16,375 million in fiscal 2004.



In fiscal 2004, the outstanding trade account receivables decreased compared
to fiscal 2003 as net sales slowed down due to inventory adjustment by Advantests customers in the second half of fiscal 2004 after a continued rise from fiscal 2003 through the first half of fiscal 2004. The amount of trade accounts payable
decreased primarily due to the decrease in inventory procurement resulting from lower projected sales for the first half of fiscal 2005 estimated as of the second half of fiscal 2004 compared to projected sales for the first half of fiscal 2004
estimated as of the second half of fiscal 2003.



Net cash
expended in investing activities was ¥8,250 million in fiscal 2004, compared to ¥5,070 million in fiscal 2003. The increase in net cash used in investing activities was primarily due to the increase in the purchases of property, plant and
equipment as a part of capital expenditures by ¥3,670 million compared to fiscal



45

##### Table of Contents

2003 to ¥8,738 million in fiscal 2004. The proceeds from the sales of available-for-sales securities increased by ¥1,105 million to ¥1,428
million in fiscal 2004, resulting in the offset of some of the increase in net cash expended for investing activities.



Advantests largest capital expenditures during fiscal 2004 consisted of its investment in equipment used in Advantests test equipment leasing
program, its investment in equipment used for research and development and its investment in manufacturing and maintenance facilities.



Advantest has budgeted ¥9.0 billion for capital expenditures in fiscal 2005. Advantests expected capital expenditures in fiscal 2005 include:



| |  |  | ¥2.0 billion allocated to equipment used in Advantests test equipment leasing program; and
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | ¥4.0 billion on equipment for research and development and manufacturing.
| | - |  | -------------------------------------------------------------------------



Advantest did not complete any large capital expenditures related to facilities and other infrastructure in fiscal 2004. Advantest currently does not
have any plans for large capital expenditure projects in fiscal 2005 or 2006.



Net cash used in financing activities was ¥63,036 million in fiscal 2004, compared to ¥6,376 million in fiscal 2003. The increase in net cash used in financing activities was primarily due to the increase in
payments made for Advantests purchases of its own shares by ¥54,480 million, compared to fiscal 2003 to ¥54,511 million in fiscal 2004. Almost all of the acquisition of Advantests own shares was effected in February 2005 in order
to implement flexible capital policy in response to changes in business conditions, and 6 million shares were purchased at ¥9,080 per share.



The outstanding amount of Advantests total long-term debt (including current installments) decreased by ¥4,543 million, or 18.4% compared to
March 31, 2004, to ¥20,083 million as of March 31, 2005. The current portion of long-term debt increased by ¥15,500 million to ¥20,043 million as of March 31, 2005. Advantests long-term debt consists of secured and unsecured
borrowings with fixed interest rates ranging from 1.05% to 4.125%, with maturity dates ranging from 2004 to 2008, and unsecured bonds with fixed interest rate of 1.88%, with maturity dates in 2005. Advantests largest issue of bonds or notes
currently outstanding consists of ¥20,000 million in principal amount of 1.88% unsecured bonds due December 14, 2005. Advantest intends to repay the bond by using its available cash. All of Advantests long-term debt is denominated in
Japanese yen. As of March 31, 2005, Advantests ratio of long-term debt (including current installments) to stockholders equity was 9.7%, compared to 11.1% as of March 31, 2004.



Advantest has various retirement and severance plans for employees, including
contributory defined benefit retirement and severance plans consisting primarily of the Employees Pension Fund plan. Advantests unfunded portion of its benefit obligations as of March 31, 2005 amounted to ¥12,765 million, ¥12,605
million of which was recognized on Advantests balance sheet as of March 31, 2005. Regarding the transmission to the Japanese government of the substitutional portion of an Employees Pension Fund plan, Advantest accounted for the
exemption from the obligations for future services and the exemption from the obligations from past services under the transfer of pension plan assets as a series of procedures in relation to liquidation transactions, and recognized a net income of
¥3,317 million on these transactions. This amount is comprised of the difference of ¥6,116 million between the cumulative benefit obligation liquidated at the time of the transfer of benefit obligations for the past services and the payment
in return to the substitutional portion to the national treasury, and the amount of ¥2,799 million recognized as unrecognized actuarial net loss. The net gain of ¥3,317 million was accounted as a decrease in the selling, general and
administrative expenses. Advantest has contributed to the Employees Pension Fund plan in accordance with the funding requirements of applicable Japanese governmental regulations. Although there is presently no immediate or significant
near-term increase expected in cash funding requirements, Advantests cash funding requirements would be affected by any changes in interest rates, rate of returns on plan assets and government regulations. The contributions paid by Advantest
under the



46

##### Table of Contents

Employees Pension Fund plan were ¥631 million in fiscal 2003, and ¥2,348 million in fiscal 2004. This increase was primarily attributable to
reserve funding at the time of transfer to corporate pension plan from the Employees Pension Fund plan. Advantest expects to contribute approximately ¥2,125 million to its domestic defined benefit plans in fiscal 2005.



Advantests funding and treasury policy (including funding for capital
expenditures), which is overseen and controlled by its Finance Department, has been and is to fund substantially all of its cash needs through cash from operating activities, cash and cash equivalents on hand and, to a lesser extent, through
external sources including debt financing. Advantest expects to fund its capital expenditures in fiscal 2004 from cash and cash equivalents on hand. In the event conditions in the semiconductor industry, and thus the semiconductor and component test
system industry, experiences a downturn in the near to medium term, Advantest may need to fund future capital expenditures and other working capital needs through the incurrence of additional debt or dilutive issuances of equity securities.



Advantests cash and cash equivalents balance increased
by ¥19,840 million in fiscal 2004 to ¥120,986 million as of March 31, 2005. At March 31, 2005, 62.0% of Advantests cash and cash equivalents were held in Japanese yen.



|5.C | RESEARCH AND DEVELOPMENT, PATENTS AND LICENSES
|--- | ----------------------------------------------



Research and Development and Product Enhancement



In order to support leading technology, Advantest undertakes research and development initiatives to develop products which play a central role in the
area of measuring technologies to support electronics, information and communications, and semiconductor manufacturing. Advantests research and development focuses on the improvements of existing products. Semiconductor and component test
systems, in particular, are highly specialized and the number of sales is relatively low, and therefore require a large and ongoing investment in development by Advantest to maintain competitiveness. Advantest also conducts research of basic
technologies. Advantests expenditures for research and development were approximately ¥23.6 billion in fiscal 2002, ¥21.6 billion in fiscal 2003 and ¥26.2 billion in fiscal 2004. Advantest employs over 1,000 engineers and other
personnel in its research and development division.

Advantest has four research and development facilities in Japan, one in the
U.S. and one in France. Advantest merged its research and development operations at the Gyoda R&D Center, which served as a development facility for measuring instruments, with the Gunma R&D Center. In addition, Advantests Kita Kyushu
R&D Center commenced operations in June 2002. The purpose of the Kita Kyushu R&D Center is to provide timely and sophisticated support to semiconductor manufacturers and design companies in Kyushu, as well as in the rest of Asia.



In February 2002, Advantest established an SoC design center at its
research and development facility in Santa Clara, California. At this SoC design center, Advantest has been carrying out research and development for new modules which can be applied to open architecture platform.



Advantest promotes joint development efforts between its various research
facilities to capitalize on the capabilities of its researchers worldwide. Advantests research and development team for semiconductor and component test systems in Japan works closely with Advantest engineers in Santa Clara, California in the
development of open architecture platforms.



Advantest has been
carrying out research and development activities for its burn-in system, concentrating its development resources on Japan Engineering Co., Ltd, an affiliated company of Advantest.



Advantest is currently engaged in the research and development of electron-beam, or e-beam, lithography technology used to
draw circuit patterns on semiconductors. Due to their throughput limitations, e-beam lithography systems are currently only used in the production of high value-added semiconductors with limited production volumes and semiconductor prototypes.
Advantest believes that further research and development will be necessary in order to attain high precision technologies for the leading design rule, in addition to the development of technologies for throughput responding to the demand for next
generation equipment.

as a group. Compensation for directors and corporate auditors must be authorized by the resolutions of the general meetings of shareholders. During fiscal 2004, all of Advantests executive officers were directors of Advantest.



For a description of Advantests equity-based compensation plans, see
Share Ownership.



Advantest set aside or
accrued during the year ended March 31, 2005 an aggregate of ¥1,509 million to provide retirement benefits for its directors and corporate auditors.



|6.C | BOARD PRACTICES
|--- | ---------------



Directors



The board of
directors has the ultimate responsibility for the administration of the affairs of Advantest. Advantests articles of incorporation limit the number of directors to 10. Directors are elected at a general meeting of shareholders, and the
standard term of directors is two years. Directors may serve any number of consecutive terms. The board of directors elects one or more representative directors from among its members, each of whom has the authority individually to represent
Advantest. From among its members, the board of directors may elect the chairman and the vice chairman. None of the directors of Advantest has a service contract with Advantest that provides for benefits upon termination of service.



Corporate Auditors



Advantests articles of incorporation provide for no more than four corporate auditors and Advantest currently has two
standing corporate auditors and two outside corporate auditors. Corporate auditors are elected at the general meeting of shareholders and the standard term of office of corporate auditors is four years. The two outside corporate auditors are those
who have not been a director or employee of Advantest or any of its subsidiaries during the five-year period immediately prior to his or her election as a corporate auditor, as required under the Commercial Code of Japan and the Law concerning
Exceptional Measures to the Commercial Code with respect to Auditing, etc. of Joint Stock Corporations, or the Special Exception Law (hereinafter, the same). Subsequent to the ordinary general meeting of shareholders to be held in June 2006, at
least half of the corporate auditors will be required to be persons who have not been a director, executive officer, manager, or employee of



54



---

##### Table of Contents

Advantest or any of its subsidiaries at any time prior to such corporate auditors election. Corporate auditors may not at the same time be directors,
executive officers, managers, or employees of Advantest or any of its subsidiaries. Advantest increased the number of required outside corporate auditors from one to two at the general meeting of shareholders held in June 2003 in order to strengthen
the auditing function of the board of corporate auditors. Corporate auditors are under a statutory duty to oversee the administration of Advantests affairs by its directors, to examine its financial statements and business reports to be
submitted annually by its board of directors to the general meetings of the shareholders and to report their opinions thereon. They are also required to attend the meetings of the board of directors and to express their opinions, but are not
entitled to vote.



Corporate auditors constitute the board of
corporate auditors. The board of corporate auditors has a statutory duty to prepare and submit an audit report to the directors each year. A corporate auditor may note his or her opinion in the audit report if his or her opinion is different from
the opinion expressed in the audit report. The board of corporate auditors is empowered to establish audit principles, the method of examination by corporate auditors of Advantests affairs and financial position and other matters concerning
the performance of the corporate auditors duties.



Advantest does not have a remuneration committee.



Significant
Differences in Corporate Governance Practices between Advantest and U.S. Companies Listed on the New York Stock Exchange



Pursuant to home country practices exemptions granted by the New York Stock Exchange, or the NYSE, Advantest is permitted to follow certain corporate
governance practices complying with Japanese laws, regulations and stock exchange rules in lieu of NYSEs listing standards. The United States Securities and Exchange Commission, or the SEC, approved changes to the NYSEs listing standards
related to corporate governance practices of listed companies in November 2003, as further amended in November 2004. Advantest is exempted from the approved changes, except for requirements that (a) Advantests audit committee satisfy the
requirements of Rule 10A-3 under the U.S. Securities Exchange Act of 1934 as amended, or the Exchange Act, (b) Advantest must disclose significant differences in the corporate governance practices followed by Advantest as compared to those followed
by domestic companies under the NYSE listing standards, (c) Advantests CEO must notify the NYSE of material non-compliance with (a) and (b), and (d) Advantest must submit annual and interim written affirmations to the NYSE. Advantests
corporate governance practices and those followed by domestic companies under the NYSE listing standards, or NYSE Corporate Governance have the following significant differences:



1. Directors.Advantest currently does not have any independent director on its board of directors. Unlike
NYSE Corporate Governance, the Commercial Code of Japan and related legislation (including the Special Exception Law), or the Code (hereinafter in Item 6.C, the same), do not require Japanese companies with boards of corporate auditors such as
Advantest to have any independent directors on its board of directors. While NYSE Corporate Governance requires that the non-management directors of each listed company meet at regularly scheduled executive sessions without management, Advantest
currently has no non-management director on its board of directors. Unlike NYSE Corporate Governance, the Code does not require, and accordingly Advantest does not have, an internal corporate organ or committee comprised of only independent
directors.



2. Committees. Under the Code and the
Special Exception Law, Advantest has elected to structure its corporate governance system as a company with corporate auditors, which are under a statutory duty to monitor, review and report on the administration of the affairs of Advantest.
Advantest, consistent with other Japanese companies with corporate auditors, but unlike NYSE Corporate Governance, does not have specified committees, including those that are responsible for director nomination, corporate governance and executive
compensation.



Pursuant to the Code, Advantests board of
directors nominates and submits a proposal for appointment of directors for shareholder approval. The shareholders vote on such nomination at Advantests general meeting of shareholders. The Code requires that the respective total amount of
remuneration to be paid to all directors and



55



---

##### Table of Contents

all corporate auditors must be determined by a resolution of the general meeting of shareholders, unless their remuneration is provided for in the Articles
of Incorporation. The distribution of remuneration among directors is broadly delegated to Advantests board of directors and the distribution of remuneration among corporate auditors is determined by the board of corporate auditors.



3. Audit Committee.Advantest plans to avail
itself of paragraph (c)(3) of Rule 10A-3 of the Exchange Act, which provides a general exemption from the audit committee requirements to a foreign private issuer with a board of corporate auditors, subject to certain requirements which continue to
be applicable under Rule 10A-3.



Consistent with the
requirements of the Code, Advantest elects its corporate auditors through a resolution adopted at a general meeting of shareholders. Advantest currently has four corporate auditors, which exceeds the minimum number of corporate auditors required
pursuant to the Code.



Unlike NYSE Corporate Governance, the
Code, among others, does not require corporate auditors to establish an expertise in accounting nor are they required to present other special knowledge and experience. Under the Code, the board of corporate auditors may determine the auditing
policies, method of investigating the conditions of the business and the assets of Advantest, and may resolve other matters concerning the execution of the corporate auditors duties, prepare auditors reports and give consent to proposals
of the nomination of corporate auditors and accounting auditors.



Advantest currently has two corporate auditors who satisfy the requirements of independent under the Code. Unlike NYSE Corporate Governance, under the Code, at least one of the corporate auditors of Advantest must be
independent, which is such person who was not a director, executive officer, manager, or employee of Advantest or any of its subsidiaries during the five-year period prior to such corporate auditors election. Subsequent to the
ordinary general meeting of shareholders to be held in June 2006, more than half of the corporate auditors will be required to be persons who have not been a director, executive officer, manager, or employee of Advantest or any of its subsidiaries
at any time prior to such corporate auditors election. Corporate auditors may not at the same time be directors, executive officers, managers, or employees of Advantest or any of its subsidiaries.



4. Corporate Governance Guidelines.Unlike NYSE Corporate
Governance, Advantest is not required to adopt or disclose corporate governance guidelines under Japanese laws and regulations, including the Code and the Securities and Exchange Law of Japan or stock exchange rules. However, Advantest is required
to disclose policies and the present conditions of its corporate governance in its annual securities report and certain other disclosure documents in accordance with the regulations under the Securities and Exchange Law of Japan and regulations
thereunder, and stock exchange rules in respect of timely disclosure.



5. Code of Business Conduct and Ethics.Unlike NYSE Corporate Governance, under Japanese law (including the Code and the Securities and Exchange Law of Japan), and stock exchange rules, Advantest is not required to adopt a
code of business conduct and ethics for directors, officers and employees. Accordingly, Advantest is not required to adopt and disclose a code of business conduct and ethics for these individuals. However, Advantest has established a code of ethics
consistent with Section 406 of the Sarbanes-Oxley Act.



6.
Shareholder Approval of Equity Compensation Plans.Unlike NYSE Corporate Governance, in which material revisions to equity-compensation plans of the listed companies are subject to shareholder approval, pursuant to the Code, if Advantest
desires to adopt an equity-compensation plan under which stock acquisition rights are granted on favorable terms to the recipient under the plan (except where such rights are granted to all of its shareholders on a pro-rata basis at the same time),
then Advantest must obtain shareholder approval by a special resolution of a general meeting of shareholders, where the quorum is one-third of the total number of voting rights and the approval of at least two-thirds of the voting rights
represented at the meeting is required.

|---- | -------------



Not applicable.



|10.B | MEMORANDUM AND ARTICLES OF ASSOCIATION
|---- | --------------------------------------



Set forth below is information relating to Advantests common stock, including brief summaries of the relevant provisions of Advantests
articles of incorporation and share handling regulations and of the Commercial Code of Japan (the Commercial Code, hereinafter in Item 10.B, the same) and related legislation, all as currently in effect.



A bill to modernize and make overall amendments to the Commercial Code by
replacing the current provisions with regard to corporations with the new company law (the New Company Law) was promulgated on July 26, 2005. The New Company Law will come into effect within one year and half after its promulgation, and
currently, it is expected that it will take effect in May 2006.



General



Advantests authorized share capital is 220,000,000
shares. The number of Advantests issued share capital as of March 31, 2005, including treasury shares, was 99,783,385. All of the issued shares are fully paid and non-assessable.



Under the Commercial Code, the transfer of shares is effected by delivery of share certificates. However, in order to assert
shareholders rights against Advantest, a shareholder must have its name and address registered on Advantests register of shareholders. For this purpose, shareholders are required to file their names, addresses and seals with the transfer
agent. Advantests transfer agent is Tokyo Securities Transfer Agent Co., Ltd., located at 4-2, Marunouchi 1-chome, Chiyoda-ku, Tokyo 100-0005, Japan. The shares have no par value.



The registered holder of deposited shares underlying the ADSs is the depositary for the ADSs. Accordingly, holders of ADSs
will not be able to directly assert their shareholders rights against Advantest.



A holder of shares may choose, at its discretion, to participate in the central clearing system for share certificates under the Law Concerning Central Clearing of Share Certificates and Other Securities of Japan.
Participating shareholders must deposit certificates representing the shares to be included in this clearing system



64

##### Table of Contents

with Japan Securities Depository Center, Inc. (JASDEC). If a holder is not a participating institution in JASDEC, it must participate through a
participating institution, such as a securities company or bank having a clearing account with JASDEC. All shares deposited with JASDEC will be registered in the name of JASDEC on Advantests register of shareholders. Each participating
shareholder will, in turn, be recorded in the register of beneficial owners prepared by Advantest based on information furnished to the transfer agent of Advantest by the participating institutions and JASDEC. These participating shareholders will
be treated in the same way as shareholders registered on Advantests register of shareholders. The register of beneficial owners is updated as of the record date on which shareholders entitled to rights pertaining to the shares are determined.
The record date is usually March 31 and September 30 of each year. To transfer deposited shares, delivery of share certificates is not required. Entry of the share transfer in the book maintained by JASDEC for participating institutions, or in the
book maintained by a participating institution for its customers, has the same effect as the delivery of share certificates. The registered beneficial owners may exercise the rights attached to the shares, such as voting rights, and will receive
dividends (if any) and will receive notices to shareholders directly from Advantest. The shares held by a person as a registered shareholder and those held by the same person as a registered beneficial owner are aggregated for these purposes.
Beneficial owners may at any time withdraw their shares from deposit and receive share certificates.



A new law to establish a new central clearing system for shares of listed companies and to eliminate the issuance and use of certificates for such shares
was promulgated in June 2004 and the relevant part of the law will come into effect within five years of the date of the promulgation. On the effective date, a new central clearing system will be established and the shares of all Japanese companies
listed on any Japanese stock exchange, including the shares of common stock of Advantest, will be subject to the new central clearing system. On the same day, all existing share certificates will become null and void and the companies are not
required to withdraw those share certificates from shareholders. The transfer of such shares will be effected through entry in the books maintained under the new central clearing system.



Objects and Purposes



Article 2 of Advantests articles of incorporation states that its objective is to engage in the following business activities:



| |  |  | the manufacture and sale of electric, electronic and physicochemical appliances and their applied equipment;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | the manufacture and sale of appliances, equipment and software related to any of the foregoing items;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | the lease and rental of equipment, appliances and other products incidental to each of the foregoing items;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | the temporary personnel service business; and
| | - |  | ---------------------------------------------



| |  |  | any and all businesses incidental to any of the foregoing items.
| | - |  | ----------------------------------------------------------------



Dividends



DividendsGeneral



Under its articles of incorporation, Advantests financial accounts are closed on March 31 of each year, and year-end dividends, if any, are paid to shareholders and beneficial owners (or registered pledgees thereof) of record at that
date.



Under the New Company Law, subject to certain limitation
on the distributable surplus, dividends, if any, may be paid to shareholders, beneficial shareholders, and pledgees of record as of a record date as set forth by Advantests articles of incorporation or as determined by the board of directors
from time to time. Dividends shall be paid by way of distribution of surplus. Dividends may be distributed in cash, or in kind subject to certain

conditions being met. Advantest may make distribution of dividends by a resolution of a general meeting of shareholders. However, Advantest may generally
determine such matters by a resolution of the board of directors under certain conditions such as that Advantests articles of incorporation so provide.



DividendsInterim cash dividends



In addition to year-end cash dividends, the board of directors may by resolution declare an interim cash dividend to shareholders, beneficial
shareholders, and pledgees of record at September 30 of each year.



Under the New Company Law, notwithstanding the necessity of obtaining approval of a general meeting of shareholders in general under the New Company Law as described above, Advantest is allowed to make payment of interim dividends during a
fiscal year by way of distribution of surplus by resolution of the board of directors; provided, however, that such payment of interim dividends shall be limited to cash dividends and also limited to once per any fiscal year.



DividendsLegal reserve



The Commercial Code provides that Advantest must set aside the following
amounts in its legal reserve until the amount of such legal reserve together with its additional paid-in capital has reached an amount equal to one quarter of its stated capital:



| |  |  | an amount equal to at least one-tenth of any amount paid by Advantest as an appropriation of retained earnings (including any payment by way of year-end dividends and bonuses to
directors and corporate auditors) for such fiscal year; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an amount equal to one-tenth of any interim dividend.
| | - |  | -----------------------------------------------------



The New Company Law provides that when a stock company like Advantest makes distribution of surplus, it shall set aside in its legal reserve or additional
paid-in capital an amount equal to 10 percent of the amount of the surplus to be decreased as a result of such distribution of surplus in accordance with the provisions set forth in an ordinance of the Ministry of Justice.



DividendsDistributable amount



The amount of earnings distributable by Advantest as year-end dividends is
limited to the excess of Advantests net assets as appearing on Advantests non-consolidated balance sheet as of the end of the last fiscal year, over the aggregate, as appearing on the same balance sheet where relevant, of:



| | (i) | its stated capital;
| | --- | -------------------



| | (ii) | its additional paid-in capital;
| | ---- | -------------------------------



| | (iii) | its accumulated legal reserve;

| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | other amounts which are provided for by an ordinance of the Ministry of Justice of Japan.
| | --- | -----------------------------------------------------------------------------------------



In the case of interim dividends, net assets and the amounts stated in (i) through (iii) above are calculated by reference
to the balance sheet as of the end of the preceding fiscal year, and adjustments are made to reflect:



| | (A) | any subsequent payment by way of appropriation of retained earnings and the related transfer to legal reserve;
| | --- | --------------------------------------------------------------------------------------------------------------



| | (B) | any subsequent transfer of retained earnings to stated capital;

Japan shall be added to the amount distributable as interim dividends as described above.



Interim dividends may not be paid where there is a risk that at the end of the fiscal year net assets might be less than the aggregate of the amounts referred to in (i) through (v) above.



Under the New Company Law, Advantest is permitted to make distribution of
surplus to the extent that the aggregate book value of the assets to be distributed to shareholders does not exceed the Distributable Amount (as defined below) as at the effective date of such distribution of surplus.



The amount of surplus at any given time shall be the amount of
Advantests assets and the book value of Advantests treasury stock after subtracting the amounts of the following items (1) through (4) as they appear on Advantests non-consolidated balance sheet as at the end of Advantests
last fiscal year, and after reflecting the changes in Advantests surplus after the end of Advantests last fiscal year, by adding the amounts of the following items (5), (6) and (7) and/or subtracting the amounts of the following items
(8), (9) and (10):



| | (1) | its liabilities;

| | (2) | its stated capital;
| | --- | -------------------



| | (3) | its additional paid-in capital and accumulated legal reserve;

paid-in capital or legal reserve);

| | (7) | (if Advantest decreased its additional paid-in capital or legal reserve after the end of the last fiscal year) the amount of decrease in its additional paid-in capital or legal
reserve (excluding the amount transferred to the stated capital);
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (8) | (if Advantest cancelled its treasury stock after the end of the last fiscal year) the book value of its treasury stock so cancelled;

period after the end of Advantests last fiscal year until the date of an extraordinary settlement of account (if any) as provided for in an ordinance of the Ministry of Justice and (c) the transfer price of its treasury stock in the same
period, after subtracting the amounts of the following items:

DividendsEx-dividend date and prescription



In Japan, the ex-dividend date and the record date for dividends precede the date of determination of the amount of the dividend to be paid. The market
price of shares generally becomes ex-dividend on the third business day before the record date.



Under the articles of incorporation, Advantest is not required to pay any dividends unclaimed for a period of three years after the date on which the
dividends first become payable.



For information as to Japanese
taxes on dividends, see TaxationJapanese Taxation.



Capital Accounts



The entire amount of the
issue price of new shares is required to be accounted for as stated capital, although Advantest may account for an amount not exceeding one-half of the issue price as additional paid-in capital.



Under the Commercial Code, Advantest may at any time transfer the whole or
any part of its additional paid-in capital and legal reserve to stated capital by resolution of the board of directors. However, under the New Company Law, resolution of general meetings of shareholders is required for such transfer of the
additional paid-in capital and legal reserve to the stated capital.



Advantest may also reduce the sum of its legal reserve and additional paid-in capital to one-quarter or more of its stated capital by resolution of a general meeting of shareholders. Under the New Company Law, Advantest may reduce the sum
of its legal reserve and additional paid-in capital without the limitation of the amount to be reduced as mentioned above.



The whole or any part of retained earnings which may be distributed as year-end dividends may also be transferred to stated capital by resolution of an
ordinary general meeting of shareholders. Under the New Company Law, not only ordinary general meetings of shareholders but also extraordinary general meetings of shareholders will be able to approve such transfer of retained earnings to stated
capital,



Stock Split



Advantest may at any time split the outstanding shares into a greater number
of shares by resolution of the board of directors. Advantest must give public notice of the stock split, specifying a record date for the stock split, not less than two weeks prior to the record date and, in addition, promptly after the stock split
takes effect, give notice to each shareholder specifying the number of shares to which the shareholder is entitled by virtue of the stock split. After the New Company Law becomes effective, no such notice to each shareholder is required.



Consolidation of Shares



Advantest may at any time consolidate shares in issue into a smaller number
of shares by a special shareholders resolution (See Voting Rights). When a consolidation of shares is to be made, Advantest must give public notice and notice to each shareholder that, within a period of not less than one month specified
in the notice, share certificates must be submitted to Advantest for exchange. Advantest must disclose the reason for the consolidation of shares at the general meeting of shareholders.

##### Table of Contents

The Unit Share System



General



Consistent with the requirements of the Commercial Code (or when the New Company Law becomes effective, the New Company Law), Advantests articles of
incorporation provide that 100 shares constitute one unit. Although the number of shares constituting a unit is included in the articles of incorporation, any amendment to the articles of incorporation reducing (but not increasing) the
number of shares constituting a unit or eliminating the provisions for the unit of shares may be made by the resolution of the board of directors rather than by the special shareholders resolution, which is otherwise required for amending the
articles of incorporation. The number of shares constituting one unit, however, cannot exceed the lesser of 1,000 shares and one two hundredths (1/200) of the number of all issued shares.



Voting Rights under the Unit Share System



Under the unit share system, shareholders shall have one voting right for each unit of shares that they hold. Any number of
shares less than a full unit will carry no voting rights.



Share Certificate for Less Than a Full Unit of Shares



Advantests articles of incorporation provide that, in general, no share certificate for any number of shares less than a unit will be issued. As the transfer of shares normally requires delivery of share
certificates, any fraction of a unit for which share certificates are not issued will not be transferable.



Repurchase by Advantest of Shares Constituting Less Than a Full Unit



A holder of shares constituting less than a full unit may require Advantest to purchase those shares at their market value
in accordance with the provisions of Advantests share handling regulations.



Request by a Holder of Shares of Sales by Advantest of Shares to Constitute a Full Unit



Advantests articles of incorporation provide that a holder of shares constituting less than a full unit may request Advantest to sell to such holder
such amount of shares which will, when added together with the shares constituting less than a full unit, constitute a full unit of shares in accordance with the provisions of Advantests share handling regulations.



Effect of the Unit Share System on Holders of ADRs



A holder who owns ADRs evidencing less than 400 ADSs will indirectly own
less than a whole unit of shares of common stock. Although, as discussed above, under the unit share system holders of less than a unit have the right to require Advantest to purchase their shares, holders of ADRs evidencing ADSs that represent
other than integral multiples of whole units are unable to withdraw the underlying shares of common stock representing less than a unit and, therefore, are unable, as a practical matter, to exercise the rights to require Advantest to purchase such
underlying shares unless Advantests articles of incorporation are amended to eliminate the provision not to issue share certificates for the numbers of shares less than a unit. As a result, access to the Japanese markets by holders of ADRs
through the withdrawal mechanism will not be available for dispositions of shares of common stock in lots less than a unit. The unit share system does not affect the transferability of ADSs, which may be transferred in lots of any size.



General Meeting of Shareholders



Advantest holds its ordinary general meeting of shareholders within three
months after the end of a fiscal year and normally in June of each year in Tokyo, Japan. In addition, Advantest may hold an extraordinary



69



---

##### Table of Contents

general meeting of shareholders whenever necessary by giving at least two weeks advance notice. Under the Commercial Code (or when the New Company Law
becomes effective, the New Company Law), notice of any shareholders meeting must be given to each shareholder having voting rights or, in the case of a non-resident shareholder, to his resident proxy or mailing address in Japan in accordance
with Advantests share handling regulations, at least two weeks before the date of the meeting. The record date for an ordinary general meeting of shareholders is March 31 each year.



Any shareholder holding at least 300 voting rights or 1% of the total number of voting rights for a period of six months or
longer may propose a matter to be considered at a general meeting of shareholders by submitting a written request to a representative director of Advantest at least eight weeks before the date of such meeting.



Voting Rights



A holder of shares constituting one or more whole units is entitled to one voting right per unit of shares subject to the
limitations on voting rights set forth in the following paragraph. In general, under the Commercial Code (or when the New Company Law becomes effective, the New Company Law), a resolution can be adopted at a general meeting of shareholders by a
majority of voting rights represented at the meeting. The Commercial Code (or when the New Company Law becomes effective, the New Company Law) and Advantests articles of incorporation require a quorum for the election of directors and
corporate auditors of not less than one-third of the voting rights of all shareholders. Advantests shareholders are not entitled to cumulative voting in the election of directors. A corporate shareholder whose outstanding shares are in turn
more than one-quarter directly or indirectly owned by Advantest (or when the New Company Law becomes effective, management of which is being controlled in substance by Advantest as provided for by an ordinance of the Ministry of Justice) does not
have voting rights.



Shareholders may exercise their voting
rights through proxies if those proxies are also shareholders who have voting rights.



The Commercial Code (or when the New Company Law becomes effective, the New Company Law) provides that a quorum of at least one-third of voting rights of all shareholders (or, when the New Company Law becomes
effective and in the event that Advantests articles of incorporations provide for a percentage more than one-third, such percentage) must be present at a shareholders meeting to approve any material corporate actions, such as:



| | (1) | amendment of the articles of incorporation,
| | --- | -------------------------------------------



| | (2) | acquisition of its own shares from a specific party;
| | --- | ----------------------------------------------------



| | (3) | consolidation of shares;

| | (4) | any offering of new shares at a specially favorable price (or any offering of stock acquisition rights to subscribe for or acquire shares of capital stock, or bonds with
stock acquisition rights at specially favorable conditions) to any persons other than shareholders;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (5) | the removal of a director (when the New Company Law becomes effective, the removal of a director who was elected by cumulative voting) or a corporate auditor;

At least two-thirds of voting rights (or, when the New Company Law becomes
effective and in the event that Advantests articles of incorporations provide for a percentage more than two-thirds, such percentage) represented at the meeting must approve these actions.



The voting rights of holders of ADSs are exercised by the depositary based on
instructions from those holders. With respect to voting by holders of ADRs, see Description of American Depositary Receipts set forth in Advantests registration statement on Form F-1 filed with the Securities and Exchange
Commission on July 22, 2002.



Subscription Rights



Holders of shares have no preemptive rights under Advantests articles
of incorporation. Under the Commercial Code, the board of directors may, however, determine that shareholders shall be given subscription rights in connection with a particular issue of new shares, stock acquisition rights or bonds with stock
acquisition rights. In this case, the rights must be given on uniform terms to all shareholders as of a specified record date by at least two weeks prior public notice to shareholders of the record date. Individual notice must be given to each
of these shareholders at least two weeks before the date of expiration of the subscription rights.



Rights to subscribe for new shares may be transferable or non-transferable by determination of the board of directors. These rights may be made at a price
substantially below the market price of the shares. Accordingly, rights offerings can result in substantial dilution or can result in rights holders not being able to realize the economic value of those rights.



Stock Acquisition Rights



Subject to certain requirements, Advantest may issue stock acquisition
rights by resolution of the board of directors. Except where the issue would be on specially favorable conditions, the issue of stock acquisition rights may be authorized by a resolution of the board of directors. Holders of stock
acquisition rights may exercise their rights to acquire a certain number of shares within the exercise period as prescribed in the terms of their stock acquisition rights. Upon exercise of stock acquisition rights, Advantest will be obliged to issue
the relevant number of new shares or alternatively to transfer the necessary number of existing shares held by it.



Liquidation Rights



In the event of a liquidation of Advantest, the assets remaining after payment of all debts, liquidation expenses and taxes will be distributed among the
shareholders in proportion to the respective numbers of shares they own.



Liability to Further Calls or Assessments



All of Advantests currently outstanding shares, including shares represented by the ADSs, are fully paid and non-assessable.

##### Table of Contents

Record Date



March 31 of each year is the record date for Advantests year-end dividends, if declared. A holder of shares constituting one or more whole units who
is registered as a holder on Advantests register of shareholders or register of beneficial owners at the close of business as of March 31 is entitled to exercise shareholders voting rights at the ordinary general meeting of shareholders
with respect to the fiscal year ending on that March 31. September 30 of each year is the record date for interim dividends, if declared. In addition, Advantest may set a record date for determining the shareholders entitled to other rights and for
other purposes by giving at least two weeks public notice.



The shares generally trade ex-dividend or ex-rights in the Japanese stock exchanges on the third business day before a record date (or if the record date is not a business day, the fourth business day prior thereto), for the purpose of
dividends or rights offerings.



Repurchase by Advantest of Shares



Advantest may acquire its own shares (i) through a stock
exchange on which such shares are listed or by way of tender offer (pursuant to an ordinary resolution of an ordinary general meeting of shareholders or a resolution of the board of directors), (ii) by purchase from a specific party (pursuant to a
special resolution of an ordinary general meeting of shareholders) or (iii) from a subsidiary of Advantest (pursuant to a resolution of the board of directors). Under the New Company Law, not only ordinary general meetings of shareholders but also
extraordinary general meetings of shareholders will be able to approve the acquisition by of its own shares in the cases of (i) and (ii) above.



When such acquisition is made by Advantest from a specific party other than a subsidiary of Advantest, any other shareholder may make a demand to a
representative director, more than five calendar days (when the New Company Law becomes effective, the number of days provided for by an ordinance of the Ministry of Justice) prior to the relevant shareholders meeting, that Advantest also
purchase the shares held by such shareholder. However, under the New Company Law, the acquisition of its own shares at a price not exceeding the then market price to be provided under an ordinance of the Ministry of Justice will not trigger the
right of any shareholder to include him/her as the seller of his/her shares in such proposed purchase.



Any such acquisition of shares must satisfy certain requirements, including that, in cases other than the acquisition by Advantest of its own shares
pursuant to a resolution of the board of directors and the acquisition by Advantest of its shares from its subsidiaries, the total amount of the purchase price may not exceed the amount of the retained earnings available for dividend payments after
taking into account any reduction, if any, of the stated capital, additional paid-in capital or legal reserve (if such reduction of the stated capital, additional paid-in capital or legal reserve has been authorized pursuant to a resolution of the
relevant ordinary general meeting of shareholders), minus the amount to be paid by way of appropriation of retained earnings for the relevant fiscal year and the amount to be transferred to stated capital in respect of the relevant fiscal year
pursuant to a resolution of an ordinary general meeting of shareholders. If Advantest purchases shares pursuant to a resolution of the board of directors or if Advantest purchases shares from its subsidiaries, the total amount of the purchase price
may not exceed the amount of the retained earnings available for an interim dividend payment minus the amount of any interim dividend Advantest actually paid. However, if it is anticipated that the net assets on the balance sheet as at the end of
the immediately following fiscal year will be less than the aggregate amount of the stated capital, additional paid-in capital and other items as described in (i) through (v) in DividendsDistributable amount above, Advantest may
not acquire such shares. Under the New Company Law, the restriction on the source of funds for the acquisition by Advantest of its own shares will be integrated into those for the distribution of surplus to the shareholders. See
Dividends.



Shares acquired by Advantest may be
held by it for any period or may be cancelled by resolution of the board of directors. Advantest may also transfer to any person the shares held by it, subject to a resolution of the board of directors, and subject also to other requirements similar
to those applicable to the issuance of new

shares. Advantest may also utilize its treasury stock for the purpose of transfer to any person upon exercise of stock acquisition rights or for the purpose
of acquiring another company by way of merger, share exchange or corporate split through exchange of treasury stock for shares or assets of the acquired company.



The Commercial Code (or when the New Company Law becomes effective, the New Company Law) generally prohibits any subsidiary
of Advantest from acquiring shares of Advantest.



Disposal of the Shares by
Advantest



Advantest is not required to send notices to a
shareholder if notices to such shareholder fail to arrive continuously for five years or more at the registered address of the shareholder in the Advantests register of shareholders or at the address otherwise notified to Advantest.



In addition, Advantest may dispose of the Shares at the then
market price of the Shares by a resolution of the Board of Directors and after giving at least three months prior public notice as well as individual notice to the shareholder at the registered address of the shareholder in the
Advantests register of shareholders or to the address otherwise notified to Advantest, and hold or deposit the proceeds for the shareholder, the location of which is unknown, if (i) notices to the shareholder fail to arrive continuously for
five years or more at the registered address of the shareholder in Advantests register of shareholders or at the address otherwise notified to Advantest, and (ii) the shareholder fails to receive dividends on the Shares continuously for five
years or more at the address registered in Advantests register of shareholders or at the address otherwise notified to Advantest.



Acquisition or Disposition of Shares



Under the Foreign Exchange and Foreign Trade Law and the cabinet orders and ministerial ordinances thereunder (collectively, the Foreign Exchange
Regulations), all aspects of regulations on foreign exchange and trade transactions are, with minor exceptions relating to inward direct investments (which are not generally applicable to Advantests shares), only subject to post
transaction reporting requirements. Acquisitions and dispositions of shares of common stock or ADSs by non-residents of Japan (including foreign corporation not resident in Japan) are generally not subject to this reporting requirement. However, the
Minister of Finance has the power to impose a licensing requirement for transactions in limited circumstances.



Dividends and Proceeds of Sales



Under the Foreign Exchange Regulations as currently in effect, dividends paid on, and the proceeds of sales in Japan of, shares held by non-residents of Japan may in general be converted into any foreign currency and repatriated abroad. The
acquisition of shares by non-residents of Japan by way of stock splits is not subject to any of the foregoing notification or reporting requirements.



Reporting of Substantial Shareholdings



Pursuant to the Securities and Exchange Law of Japan and regulations thereunder, a person or group of persons beneficially holding more than 5% of the
total shares with voting rights (for this purpose shares issuable upon exercise of stock acquisition rights held by the person or persons are counted in the calculation of the holding and the total shares in issue) of a company listed on any
Japanese stock exchange is required to file with the director of a competent local finance bureau, within five business days a report containing the identity of such person or persons, the purpose of such holding and certain other information
prescribed by regulations. A similar report must also be made (with certain exceptions) if the percentage of such holding subsequently increases or decreases by 1% or more or if any change occurs in material matters set out in reports previously
filed.



|10.C | MATERIAL CONTRACTS

All contracts concluded by Advantest during the two years preceding this filing were entered into in the ordinary course of business.

|10.D | EXCHANGE CONTROLS
|---- | -----------------



The Foreign Exchange and Foreign Trade Law of Japan and its related cabinet orders and ministerial ordinances (the Foreign Exchange
Regulations) govern the acquisition and holding of shares of capital stock of Advantest by exchange non-residents and by foreign investors. The Foreign Exchange Regulations currently in effect do not, however, affect
transactions between exchange non-residents to purchase or sell shares outside Japan using currencies other than Japanese yen.



Exchange non-residents are:



| |  |  | individuals who do not reside in Japan; and
| | - |  | -------------------------------------------



| |  |  | corporations whose principal offices are located outside Japan.
| | - |  | ---------------------------------------------------------------



Generally, branches and other offices of non-resident corporations that are located within Japan are regarded as residents of Japan. Conversely, branches
and other offices of Japanese corporations located outside Japan are regarded as exchange non-residents.



Foreign investors are:



| |  |  | individuals who are exchange non-residents;
| | - |  | -------------------------------------------



| |  |  | corporations that are organized under the laws of foreign countries or whose principal offices are located outside of Japan; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | corporations (1) of which 50% or more of the total voting rights of their shares are held by individuals who are exchange non-residents and/or corporations (a) that are organized
under the laws of foreign countries or (b) whose principal offices are located outside of Japan or (2) a majority of whose officers, or officers having the power of representation, are individuals who are exchange non-residents.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



In general, the acquisition of shares of a
Japanese company (such as the shares of capital stock of Advantest) by an exchange non-resident from a resident of Japan is not subject to any prior filing requirements. In certain limited circumstances, however, the Minister of Finance may require
prior approval of an acquisition of this type. While prior approval, as described above, is not required, in the case where a resident of Japan transfers shares of a Japanese company (such as the shares of capital stock of Advantest) for
consideration exceeding ¥100 million to an exchange non-resident, the resident of Japan who transfers the shares is required to report the transfer to the Minister of Finance within 20 days from the date of the transfer, unless the transfer was
made through a bank, securities company or financial futures trader licensed under Japanese law.



If a foreign investor acquires shares of a Japanese company that is listed on a Japanese stock exchange (such as the shares of capital stock of Advantest)
and, as a result of the acquisition, the foreign investor, in combination with any existing holdings, directly or indirectly holds 10% or more of the issued shares of the relevant company, the foreign investor must file a report of the acquisition
with the Minister of Finance and any other competent Ministers having jurisdiction over that Japanese company within 15 days from and including the date of the acquisition, except where the offering of the companys shares was made overseas. In
limited circumstances, such as where the foreign investor is in a country that is not listed on an exemption schedule in the Foreign Exchange Regulations, a prior notification of the acquisition must be filed with the Minister of Finance and any
other competent Ministers, who may then modify or prohibit the proposed acquisition.



Under the Foreign Exchange Regulations dividends paid on, and the proceeds of sales in Japan of, shares held by non-residents of Japan may in general be converted into any foreign currency and repatriated abroad.
Under the terms of the deposit agreement pursuant to which Advantests ADSs are issued, the Depositary is required, to the extent that in its judgment it can convert yen on a reasonable basis into dollars and transfer the resulting dollars to
the U.S., to convert all cash dividends that it receives in respect of deposited shares into dollars and to distribute the amount received (after deduction of applicable withholding taxes) to the holder of ADSs.

|10.E | TAXATION
|---- | --------



The following discussion is a general summary of the principal U.S. federal income and Japanese national tax consequences of the acquisition, ownership
and disposition of the shares of common stock of Advantest (the Shares) or ADSs. This summary does not purport to address all the material tax consequences that may be relevant to the holders of the Shares or ADSs, and does not take into
account the specific circumstances of any particular investors, some of which (such as tax-exempt entities, banks, insurance companies, broker-dealers, traders in securities that elect to use a mark-to-market method of accounting for their
securities holdings, regulated investment companies, real estate investment trusts, investors liable for alternative minimum tax, partnerships and other pass-through entities, investors that own or are treated as owning 10% or more of
Advantests voting stock, investors that hold the Shares or ADSs as part of a straddle, hedge, conversion or constructive sale transaction or other integrated transaction and U.S. Holders (as defined below) whose functional currency is not the
U.S. dollar) may be subject to special tax rules. This summary is based on the tax laws and regulations of the United States and Japan, judicial decisions and published rulings and administrative pronouncements as in effect on the date hereof, as
well as on the current income tax convention between the United States and Japan (the Treaty), as described below, all of which are subject to change (possibly with retroactive effect), and/or to differing interpretations. This summary
is also based in part upon the representations of the depositary and the assumption that each obligation in the deposit agreement referred to in Description of American Depositary Receipts set forth in Advantests registration
statement on Form F-1 filed with the Securities and Exchange Commission on July 22, 2002, and in any related agreement, will be performed under its terms.



For purposes of this discussion, a U.S. Holder is any beneficial owner of the Shares or ADSs that, for U.S. federal income tax purposes, is:



| | (1) | an individual who is a citizen or resident of the United States,
| | --- | ----------------------------------------------------------------



| | (2) | a corporation or other entity organized in or under the laws of the United States or any State thereof or the District of Columbia,
| | --- | -----------------------------------------------------------------------------------------------------------------------------------



| | (3) | an estate the income of which is subject to U.S. federal income tax without regard to its source, or
| | --- | ----------------------------------------------------------------------------------------------------



| | (4) | a trust that is subject to the primary supervision of a U.S. court and the control of one or more U.S. persons, or that has a valid election in effect under applicable Treasury
regulations to be treated as a U.S. person.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



An
Eligible U.S. Holder is a U.S. Holder that:



| | (1) | is a resident of the United States for purposes of the Treaty,
| | --- | --------------------------------------------------------------



| | (2) | does not maintain a permanent establishment in Japan (a) with which the Shares or ADSs are effectively connected or (b) of which the Shares or ADSs form part of the business
property, and
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (3) | is eligible for benefits under the Treaty, with respect to income and gain derived in connection with the Shares or ADSs.
| | --- | -------------------------------------------------------------------------------------------------------------------------



If a partnership holds the Shares or ADSs, the tax treatment of a partner
generally will depend upon the status of the partner and the activities of the partnership. A partner of a partnership holding the Shares or ADSs is urged to consult its tax advisor.



This summary does not address any aspects of U.S. federal tax law other than income taxation and does not discuss any
aspects of Japanese tax law other than income taxation as limited to national taxes, inheritance and gift taxation and securities transfer taxation. This summary also does not cover any state or local, or non-U.S., non-Japanese tax considerations.
Investors are urged to consult their tax advisors regarding the U.S. federal, state, local and Japanese and other tax consequences of acquiring, owning and disposing of Shares or ADSs. In particular, where relevant, investors are urged to confirm
their status as Eligible U.S. Holders with their tax advisors and to discuss with their tax advisors any possible consequences of their failure to qualify as Eligible U.S. Holders.

##### Table of Contents

In general, taking into account the earlier assumptions, for purposes of the Treaty, and for U.S. federal
and Japanese income tax purposes, owners of ADRs evidencing ADSs will be treated as the owners of the Shares represented by those ADSs, and exchanges of the Shares for ADSs, and exchanges of ADSs for the Shares, will not be subject to U.S. federal
or Japanese income tax.



This discussion below is intended for
general information only and does not constitute a complete analysis of all tax consequences relating to ownership of Shares or ADSs. Investors in Shares or ADSs should consult their own tax advisors concerning the tax consequences of their
particular situations.



Japanese Taxation



The following is a summary of the principal Japanese tax consequences
(limited to national taxes) to holders of the Shares and of ADRs evidencing ADSs representing the Shares who are either individuals who are not residents of Japan or non-Japanese corporations, without a permanent establishment in Japan
(non-resident Holders).



Generally, a non-resident
of Japan or a non-Japanese corporation is subject to Japanese withholding tax on dividends paid by Japanese corporations. Stock splits in themselves are not subject to Japanese income tax.



In the absence of an applicable tax treaty, convention or agreement reducing
the maximum rate of Japanese withholding tax or allowing exemption from Japanese withholding tax, the rate of Japanese withholding tax applicable to dividends paid by Japanese corporations to non-residents of Japan or non-Japanese corporations is
20%. With respect to dividends paid on listed shares issued by a Japanese corporation (such as the Shares) to any corporate or individual shareholders (including those shareholders who are non-Japanese corporations or non-residents of Japan, such as
non-resident Holders), except for any individual shareholder who holds 5% or more of the total issued shares of the relevant Japanese corporation, the aforementioned 20% withholding tax rate is reduced to (i) 7% for dividends due and payable on or
before March 31, 2008, and (ii) 15% for dividends due and payable on or after April 1, 2008. At the date of this annual report, Japan has income tax treaties, conventions or agreements whereby the above-mentioned withholding tax rate is reduced, in
most cases to 15% for portfolio investors with, among other countries, Australia, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, New Zealand, Norway, Singapore, Spain, Sweden, Switzerland and the
U.K.



Under the Treaty, the maximum rate of Japanese
withholding tax which may be imposed on dividends paid by a Japanese corporation to an Eligible U.S. Holder that is a portfolio investor is generally limited to 10% of the gross amount actually distributed and Japanese withholding tax with respect
to dividends paid by a Japanese corporation to an Eligible U.S. Holder that is a pension fund is exempt from Japanese taxation by way of withholding or otherwise, unless such dividends are derived from the carrying on of a business, directly or
indirectly, by such pension fund.



If the maximum tax rate
provided for in the income tax treaty applicable to dividends paid by Advantest to any particular non-resident Holder is lower than the withholding tax rate otherwise applicable under Japanese tax law or any particular non-resident Holder is exempt
from Japanese income tax with respect to such dividends under the income tax treaty applicable to such particular non-resident Holder, such non-resident Holder who is entitled to a reduced rate of, or exemption from, Japanese withholding tax on
payment of dividends on the Shares by Advantest is required to submit an Application Form for Income Tax Convention Regarding Relief from Japanese Income Tax on Dividends in advance through Advantest to the relevant tax authority before the payment
of dividends. A standing proxy for non-resident Holders of a Japanese corporation may provide this application service. With respect to ADSs, this reduced rate or exemption is applicable if the Depositary or its agent submits two Application Forms
(one before payment of dividends, the other within eight months after Advantests fiscal year-end or semi-fiscal year-end). To claim this reduced rate or exemption, any relevant non-resident Holder of ADSs will be required to file a proof of
taxpayer status, residence and beneficial ownership (as applicable) and to provide other information or documents as may be required by the Depositary. A non-resident



76

##### Table of Contents

Holder who is entitled, under an applicable income tax treaty, to a reduced treaty rate lower than the withholding tax rate otherwise applicable under
Japanese tax law or an exemption from the withholding tax, but failed to submit the required application in advance will be entitled to claim the refund of withholding taxes withheld in excess of the rate under an applicable tax treaty (if such
non-resident Holder is entitled to a reduced treaty rate under the applicable income tax treaty) or the whole of the withholding tax withheld (if such non-resident Holder is entitled to exemption under the applicable income tax treaty) from the
relevant Japanese tax authority.



Gains derived from the sale
of the Shares or ADSs outside Japan by a non-resident Holder holding such Shares or ADSs as portfolio investors are, in general, not subject to Japanese income or corporation tax. Eligible U.S. Holders are not subject to Japanese income or
corporation tax with respect to such gains under the Treaty.



Japanese inheritance and gift taxes at progressive rates may be payable by an individual who has acquired the Shares or ADSs as a legatee, heir or donee even though neither the individual nor the deceased nor donor is a Japanese resident.



Holders of the Shares or ADSs should consult their tax
advisors regarding the effect of these taxes and, in the case of U.S. Holders, the possible application of the Estate and Gift Tax Treaty between the U.S. and Japan.



U.S. Federal Income Taxation



U.S. Holders



The following discussion is a summary of the principal U.S. federal income tax consequences to holders of Shares and of ADSs that are U.S. Holders and that hold those
Shares or ADSs as capital assets (generally, for investment purposes).



Taxation of Dividends



Subject to the passive foreign investment company rules discussed below, the gross amount of any distribution made by Advantest in respect of Shares or ADSs (without reduction for Japanese withholding taxes) will constitute a taxable
dividend to the extent paid out of current or accumulated earnings and profits of Advantest, as determined under U.S. federal income tax principles. The U.S. dollar amount of such a dividend generally will be included in the gross income of a U.S.
Holder, as ordinary income, when the dividend is actually or constructively received by the U.S. Holder, in the case of Shares, or by the depositary, in the case of ADSs. Dividends paid by us will not be eligible for the dividends-received deduction
generally allowed to U.S. corporations in respect of dividends received from other U.S. corporations.



Subject to certain exceptions for short-term and hedged positions, and provided that we are not a passive foreign investment company (as discussed below),
dividends received by certain U.S. Holders (including individuals) prior to January 1, 2009 with respect to the Shares or ADSs will be subject to U.S. federal income taxation at a maximum rate of 15%. Investors should be aware that the U.S. Treasury
Department has announced its intention to promulgate rules pursuant to which shareholders (and intermediaries) will be permitted to rely on certifications from issuers to establish that dividends qualify for the reduced rate of U.S. federal income
taxation. Because such procedures have not yet been issued, we are not certain that we will be able to comply with them. U.S. Holders of ADSs or Shares should consult their own tax advisors regarding the availability of the reduced rate in the light
of their own particular circumstances.



The U.S. dollar amount
of a dividend paid in Japanese yen will be determined based on the Japanese yen/U.S. dollar exchange rate in effect on the date that dividend is included in the gross income of the U.S. Holder, regardless of whether the payment is converted into
U.S. dollars on such date. If the Japanese yen received as a dividend is not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a tax basis in such Japanese yen equal to its U.S. dollar value on the date of receipt.
Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date the dividend payment is included in the gross income of a U.S. Holder through the date that payment is converted into U.S. dollars (or the U.S.
Holder



77

otherwise disposes of the Japanese yen) will be treated as U.S. source ordinary income or loss. U.S. Holders should consult their own tax advisors regarding
the calculation and U.S. federal income tax treatment of foreign currency gain or loss.



To the extent, if any, that the amount of any distribution received by a U.S. Holder in respect of Shares or ADSs exceeds Advantests current and accumulated earnings and profits, as determined under U.S. federal
income tax principles, the distribution first will be treated as a tax-free return of capital to the extent of the U.S. Holders adjusted tax basis in those Shares or ADSs, and thereafter will be treated as U.S. source capital gain.



Distributions of additional Shares of common stock that are made to U.S.
Holders with respect to their Shares or ADSs and that are part of a pro rata distribution to all of Advantests shareholders generally will not be subject to U.S. federal income tax.



For U.S. foreign tax credit purposes, dividends included in gross income by a U.S. Holder in respect of Shares or ADSs will
constitute income from sources outside the United States, and will be subject to various classifications and other limitations. Subject to generally applicable limitations under U.S. federal income tax law and the New Treaty, any Japanese
withholding tax imposed in respect of an Advantest dividend may be claimed as a credit against the U.S. federal income tax liability of a U.S. Holder, or if the U.S. Holder does not elect to claim a foreign tax credit for any foreign taxes paid
during the taxable year as a deduction from such U.S. Holders taxable income. Special rules generally will apply to the calculation of foreign tax credits in respect of dividend income that qualifies for preferential tax rates of U.S. federal
income tax. Additionally, special rules apply to individuals whose foreign source income during the taxable year consists entirely of qualified passive income and whose creditable foreign taxes paid or accrued during the taxable year do
not exceed $300 ($600 in the case of a joint return). Further, under some circumstances, a U.S. Holder that:



| | (i) | has held Shares or ADSs for less than a specified minimum period, or
| | --- | --------------------------------------------------------------------



| | (ii) | is obligated to make payments related to Advantest dividends,
| | ---- | -------------------------------------------------------------



will not be allowed a foreign tax credit for Japanese taxes imposed on Advantest dividends.



Investors are urged to consult their tax advisors regarding the availability of the foreign tax credit under their
particular circumstances. The U.S. Internal Revenue Service (the IRS) has expressed concern that parties to whom ADSs are released may be taking actions that are inconsistent with the claiming of foreign tax credits by U.S. Holders of
ADSs. Accordingly, investors should be aware that the discussion above regarding the creditability of Japanese withholding tax on dividends could be affected by future actions that may be taken by the IRS.



Taxation of Capital Gains



In general, upon a sale or other taxable disposition of Shares or ADSs, a
U.S. Holder will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the amount realized on the sale or other taxable disposition and the U.S. Holders adjusted tax basis in those Shares or
ADSs. A U.S. Holder generally will have an adjusted tax basis in the Shares or ADSs equal to their U.S. dollar cost. Subject to the passive investment company rules discussed below, gain or loss recognized on the sale or other taxable disposition
generally will be capital gain or loss and, if the U.S. Holders holding period for those Shares or ADSs exceeds one year, will be long-term capital gain or loss. Certain U.S. Holders, including individuals, are eligible for preferential rates
of U.S. federal income tax in respect of long-term capital gain. Under U.S. federal tax law, the deduction of capital losses is subject to limitations. Any gain or loss recognized by a U.S. Holder in respect of the sale or other disposition of
Shares or ADSs generally will be treated as derived from U.S. sources for foreign tax credit purposes.



Deposits and withdrawals of Shares in exchange for ADSs will not result in the realization of gain or loss for U.S. federal income tax purposes.

Passive Foreign Investment Companies



A non-U.S. corporation generally will be classified as a passive foreign investment company (a PFIC) for U.S.
federal income tax purposes in any taxable year in which, after applying look-through rules, either (1) at least 75% of its gross income is passive income, or (2) on average at least 50% of the gross value of its assets is attributable to assets
that produce passive income or are held for the production of passive income. Passive income for this purpose generally includes dividends, interest, royalties, rents and gains from commodities and securities transactions. The PFIC determination is
made annually and generally is based on the value of a non-U.S. corporations assets (including goodwill) and the composition of its income for the relevant tax year.



Based on current estimates of its income and assets, Advantest does not believe that it will be a PFIC for its current
taxable year, and intends to continue its operations in such a manner that it will not become a PFIC in the future. However, Advantest can provide no assurance that it will not become a PFIC in the current or any future taxable year due to changes
in its asset or income composition, a decrease in the price of its Shares (which is used as a measure of goodwill as an asset) or for other reasons. If Advantest becomes a PFIC, U.S. Holders could be subject to additional U.S. federal income taxes
on gain recognized with respect to the Shares or ADSs and on certain excess distributions (generally distributions in excess of 125% of the average distribution over a three-year period, or shorter holding period for the Shares or ADSs).
In addition, an interest charge may apply to the portion of the U.S. federal income tax liability on such gains or distributions treated under the PFIC rules as having been deferred by the U.S. Holder. Moreover, dividends that a U.S. Holder receives
from us will not be eligible for the reduced U.S. federal income tax rates applicable to dividends described above if we are a PFIC either in the taxable year of the distribution or the preceding taxable year (and instead will be taxable at rates
applicable to ordinary income). Advantest will inform U.S. Holders if it believes that it will be classified as a PFIC in any taxable year. If a U.S. Holder holds Shares or ADSs in any taxable year in which Advantest is a PFIC, such U.S. Holder will
be required to file an information statement with the IRS.



U.S. Holders are urged to consult their tax advisors concerning the U.S federal income tax consequences of holding Shares or ADSs if Advantest were considered a PFIC in any year.



Non-U.S. Holders



The following discussion is a summary of the principal U.S. federal income tax consequences to beneficial holders of Shares or ADSs that are neither U.S.
Holders nor partnerships for U.S. federal income tax purposes (Non-U.S. Holders).



Subject to the discussion below under Backup Withholding and Information Reporting, a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax in respect of distributions in
respect of the Shares or ADSs unless the distributions are effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States (and, if an applicable tax treaty requires, are attributable to a U.S. permanent
establishment or fixed base of such Non-U.S. Holder).



Subject
to the discussion below under Backup Withholding and Information Reporting, a Non-U.S. Holder generally will not be subject to U.S. federal income tax in respect of gain recognized on a sale or other taxable disposition of Shares, unless
(i) the gain is effectively connected with a trade or business conducted by the Non-U.S. Holder within the United States (and, if an applicable tax treaty requires, is attributable to a U.S. permanent establishment or fixed base of such Non-U.S.
Holder), or (ii) the Non-U.S. Holder is an individual who was present in the United States for 183 or more days in the taxable year of the disposition and other conditions are met.



Backup Withholding and Information Reporting



In general, except in the case of certain exempt recipients (such as corporations), information reporting requirements will
apply to dividends paid to a U.S. Holder in respect of Shares or ADSs, and to the proceeds

received by a U.S. Holder upon the sale, exchange or redemption of Shares or ADSs within the United States or through certain U.S.-related financial
intermediaries. Furthermore, a backup withholding tax (currently at a rate of 28%) may apply to such payments or proceeds if a U.S. Holder fails to provide an accurate tax identification number and make appropriate certifications in the required
manner.



Dividends paid to a Non-U.S. Holder in respect of
Shares or ADSs, and proceeds received upon the sale, exchange or redemption of Shares or ADSs by a Non-U.S. Holder, generally are exempt from information reporting and backup withholding under current U.S. federal income tax law. However, a Non-U.S.
Holder may be required to provide certification under penalty of perjury to ensure that exemption. Persons required to establish their exempt status generally must provide such certification on IRS Form W-9, entitled Request for Taxpayer
Identification Number and Certification, in the case of U.S. Holders, and on IRS Form W-8BEN, entitled Certificate of Foreign Status (or other appropriate IRS Form W-8), in the case of Non-U.S. Holders.



Backup withholding is not an additional tax. The amount of backup withholding
imposed on a payment to a U.S. Holder will generally be refunded or allowed as a credit against the holders U.S. federal income tax liability provided that the required information is properly furnished to the IRS.



THE SUMMARY OF U.S. FEDERAL INCOME AND JAPANESE TAX CONSEQUENCES SET OUT
ABOVE IS INTENDED FOR GENERAL INFORMATION PURPOSES ONLY. INVESTORS IN THE SHARES OR ADSs ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISORS WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF OWNING OR DISPOSING OF SHARES OR ADSs BASED ON THEIR
PARTICULAR CIRCUMSTANCES.

None.



ITEM 14.    MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS



None.



ITEM 15.    CONTROLS AND PROCEDURES



ITEM 15A.    DISCLOSURES CONTROLS AND PROCEDURES



Advantest performed an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures as of the end of fiscal 2004.
Disclosure controls and procedures are designed to ensure that the material financial and non-financial information required to be disclosed in the reports that Advantest files, or submits, under the Exchange Act is accumulated and communicated to
its management including the chief executive officer and the principal accounting and financial officer to allow timely decisions regarding required disclosure. The disclosure controls and procedures also ensures that the reports that it files or
submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Commissions rules and forms. The evaluation was performed under the supervision of Toshio Maruyama, Advantests
Representative Board Director, President and CEO and Hitoshi Owada, Advantests Director and Managing Executive Officer. Advantests disclosure and controls and procedures are designed to provide reasonable assurance of achieving its
objectives. Managerial judgment was necessary to evaluate the cost-benefit relationship of possible controls and procedures. Mr. Maruyama and Mr. Owada have concluded that Advantests disclosure controls and procedures are effective at the
reasonable assurance level.



There have been no changes in
Advantests internal control over financial reporting during fiscal 2004 that have materially affected, or are reasonably likely to materially affect, Advantests internal control over financial reporting.



ITEM 16.    [RESERVED]



ITEM 16A.    AUDIT COMMITTEE FINANCIAL EXPERT



Advantest maintains a corporate auditor system, in accordance with the Commercial Code of Japan and the Special Exception Law, or the Code (hereinafter in
Item 16.A, the same). Advantests board of corporate auditors is comprised of four corporate auditors, two of whom are outside corporate auditors. Each corporate auditor has been appointed at shareholders meetings and has certain
statutory powers independently, including auditing the business affairs and accounts of Advantest.



Advantests board of corporate auditors has determined that it does not have an audit committee financial expert serving on the board of
corporate auditors. The qualifications for, and powers of, the corporate auditor delineated in the Code are different from those anticipated for any audit committee financial expert. Corporate auditors have the authority to be given reports from a
certified public accountant or an accounting firm concerning audits, including technical accounting matters. At the same time, each corporate auditor has the authority to consult internal and external experts on accounting matters. Each corporate
auditor must fulfill the requirements under Japanese laws and regulations and otherwise follow Japanese corporate governance practices and accordingly, Advantests board of corporate auditors has confirmed that it is not necessarily fundamental
for Advantest to nominate as corporate auditor a person who meets the definition of audit committee financial expert. Although Advantest does not have an audit committee financial expert on its board of corporate auditors, Advantest believes that
Advantests current corporate governance system, taken as a whole, including the corporate auditors ability to consult internal and external experts, is fully equivalent to a system having an audit committee financial expert on its board
of corporate auditors.

Report of Independent Registered Public Accounting Firm



The Board of Directors and Stockholders

Advantest Corporation:



We have audited the consolidated balance sheet of Advantest Corporation and subsidiaries as of March 31, 2004, and the
related consolidated statements of operations, stockholders equity and cash flows for each of the years in the two-year period ended March 31, 2004 (expressed in yen). These consolidated financial statements are the responsibility of the
Companys management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.



We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for
our opinion.



In our opinion, the consolidated financial
statements referred to above present fairly, in all material respects, the financial position of Advantest Corporation and subsidiaries as of March 31, 2004, and the results of their operations and their cash flows for each of the years in the
two-year period ended March 31, 2004, in conformity with U.S. generally accepted accounting principles.

Report of Independent Registered Public Accounting Firm



The Board of Directors and Shareholders

Advantest Corporation:



We have audited the accompanying consolidated balance sheet of Advantest Corporation and subsidiaries (the Company) as of March 31, 2005, and
the related consolidated statements of operations, shareholders equity, and cash flows for the year then ended, all expressed in Japanese yen. These consolidated financial statements are the responsibility of the Companys management. Our
responsibility is to express an opinion on these financial statements based on our audit.



We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Companys internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining,
on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We
believe that our audit provides a reasonable basis for our opinion.



In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Advantest Corporation and subsidiaries at March 31, 2005, and the consolidated results of their
operations and their cash flows for the year then ended, in conformity with U.S. generally accepted accounting principles.



As discussed in Note 1 to the consolidated financial statements, in 2005 the Company changed its method of accounting for stock-based compensation.



We have also reviewed the translation of the financial
statements mentioned above into United States dollars on the basis described in Note 2. In our opinion, such statements have been translated on such basis.

ADVANTEST CORPORATION

AND SUBSIDIARIES



Notes to Consolidated Financial Statements



(1) Description of Business and Summary of Significant Accounting Policies and Practices



(a) Description of Business



The company and subsidiaries (collectively Advantest)
manufacture and sell semiconductor and component test system product group and mechatronics-related product group such as test handlers and device interfaces. Advantest also engages in research and development activities and provides maintenance and
support services associated with these products.



In
conjunction with its business and organizational restructuring, effective April 1, 2004, Advantest reclassified its two previous segments, automated test equipment and measuring instruments business segment, into three business segments:
semi-conductor and component test system; mechatronics system; and services, support and others.



Description of the business by segment is as follows:



The semiconductor and component test system business provides customers with test system products for the semiconductor industry and the electronic parts
industry. Product lines provided by the semiconductor and component test system segment include test systems for memory semiconductors for memory semiconductor devices and test systems for SoC semiconductors for non memory semiconductor devices.



The mechatronics system business provides product lines such
as test handlers, mechatronic-applied products, for handling semiconductor devices and device interfaces that serve as interfaces with the devices that are measured and operations related to nano-technology products.



The services, support and others business consists of comprehensive customer
solutions provided in connection with the above businesses, support services, equipment lease business and others.



(b) Principles of Consolidation



The Company and its domestic subsidiaries maintain their records and also prepare their statutory financial statements in accordance with accounting
principles generally accepted in Japan, and its foreign subsidiaries in conformity with the standards of the country of their domicile. Certain adjustments and reclassifications have been incorporated in the accompanying consolidated financial
statements to present them in conformity with accounting principles generally accepted in the United States of America. These adjustments are not recorded in the statutory books of account.



The consolidated financial statements include the accounts of the Company and
its majority owned subsidiaries. Advantest is not involved with any variable interest entities as, defined by FASB Interpretation No. 46 (revised December 2003) Consolidation of Variable Interest Entities. All significant intercompany
balances and transactions have been eliminated in consolidation.



(c) Cash Equivalents



Cash equivalents
consist of deposits and certificates of deposit with an initial maturity of three months or less from the date of purchase. Advantest considers all highly liquid debt instruments with original maturities of three months or less to be cash
equivalents.

(d) Allowance for Doubtful Accounts



Advantest recognizes an allowance for doubtful accounts to ensure that trade
receivables are not overstated due to uncollectability, which represents Advantests best estimate of the amount of probable credit losses in Advantests existing trade receivables. Advantest periodically reviews its estimated allowances
for doubtful accounts taking into account the customers payment history, assessing the customers current financial position and considering other information that is publicly available and the customers credit worthiness.
Additional reviews are undertaken upon reports of significant changes in the financial condition of Advantests significant customers and the semiconductor industry.



(e) Inventories



Inventories are stated at the lower of cost or market. Cost is determined using the average cost method.



(f) Investments in Affiliated Companies



Investments in affiliated companies owned 20% to 50%, where Advantest
exercises significant influence over their operating and financial policies, are accounted for on the equity method. All significant intercompany profits from affiliates have been eliminated.



(g) Investment Securities



Investment securities at March 31, 2004 and 2005 consist of marketable and
non-marketable equity securities. Advantest classifies its marketable equity securities as available-for-sale.



Available-for-sale securities are recorded at fair value. Unrealized gains and losses, net of the related tax effect, on available-for-sale securities are
excluded from earnings and are reported as a component of accumulated other comprehensive income (loss) until realized. A decline in the fair value of any available-for-sale security below cost that is deemed to be other than temporary results in an
impairment loss. The impairment is charged to earnings and a new cost basis for the security is established. Dividend income is recognized when earned.



On a continuous basis, but no less frequently than at the end of every half year, Advantest evaluates the cost basis of an available-for-sale security for
possible impairment. Factors considered in assessing whether an indication of other than temporary impairment exists include: the degree of change in ratio of market prices per share to book value per share at the date of evaluation compared to that
of the date of acquisition, the financial condition and prospects of each investee company, industry conditions in which the investee company operates, the period of time the fair value of an available-for-sale security has been below the cost basis
of the investment and other relevant factors. Impairment to be recognized is measured based on the amount by which the carrying amount of the investment exceeds the fair value of the investment. Fair value is determined based on quoted market
prices, projected discounted cash flow or other valuation techniques as appropriate.



The cost of a security sold or the amount reclassified out of accumulated other comprehensive income (loss) into earnings is determined by the average cost method.



Non-marketable investment securities are carried at cost. On a periodic
basis, Advantest evaluates the investments for the possible impairment. If the fair value of the investment securities is estimated to have declined and such decline is judged to be other than temporary, Advantest recognizes the impairment of the
investment and the carrying value is reduced to its fair value. The impairment is charged to earnings and a new cost basis for the security is established.

(h) Derivative Financial Instruments



Derivative financial instruments are accounted for under Statement of
Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative Instruments and Hedging Activities, and SFAS No. 138, Accounting for Certain Derivative Instruments and Certain Hedging Activities, an amendment
of FASB Statement No. 133. SFAS No. 133, as amended, standardizes the accounting for derivative instruments, including certain derivative instruments embedded in other contracts. Under SFAS No. 133, as amended, entities are required to carry
all derivative instruments in the consolidated balance sheets at fair value. The accounting for changes in the fair value (that is, gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a
hedging relationship and, if so, the reason for holding the instrument. If certain conditions are met, entities may elect to designate a derivative instrument as a hedge of exposures to changes in fair values, cash flows, or foreign currencies. If
the hedged exposure is a fair value exposure, the gain or loss on the derivative instrument is recognized in earnings in the period of change together with the offsetting loss or gain on the hedged item attributable to the risk being hedged. If the
hedged exposure is a cash flow exposure, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of other comprehensive income (loss) and subsequently reclassified into earnings when the forecasted
transaction affects earnings. Any amounts excluded from the assessment of hedge effectiveness as well as the ineffective portion of the gain or loss are reported in earnings immediately. If the derivative instrument is not designated as a hedge, the
gain or loss is recognized in earnings in the period of change.



Advantest uses foreign exchange forward contracts to manage currency exposure, resulting from changes in foreign currency exchange rates, on trade receivables. However, these contracts do not qualify for hedge accounting since they do not
meet the hedging criteria specified by SFAS No. 133.



Foreign
exchange forward contracts generally have maturities of several months. These contracts are used to reduce Advantests risk associated with exchange rate movements, as gains and losses on these contracts are intended to offset exchange losses
and gains on underlying exposures. Changes in fair value of foreign exchange forward contracts are recognized in earnings under the caption of other income (expense).



Advantest does not, as a matter of policy, enter into derivative transactions for the purpose of speculation.



(i) Property, Plant and Equipment



Property, plant and equipment is stated at cost.



Depreciation is computed principally using the declining-balance method
except for buildings for the Company and its domestic subsidiaries and the straight-line method over estimated useful lives of the assets for foreign subsidiaries. Buildings are principally depreciated using the straight-line method over their
estimated useful lives. The depreciation period for significant assets ranges from 15 years to 50 years for buildings, 4 years to 10 years for machinery and equipment, and 2 years to 5 years for furniture and fixtures.



Depreciation expense was ¥8,670 million, ¥7,563 million and
¥7,231 million ($67,334 thousand) in the years ended March 31, 2003, 2004 and 2005, respectively.



(j) Intangible Assets and Other Assets



Intangible assets principally consist of licenses, goodwill and computer software for internal-use, including computer software under capital leases.
Other assets consist of investments (other than investment securities), security deposits and prepaid expenses, of which no one individual item was material to the consolidated financial statements of Advantest.

ADVANTEST CORPORATION

AND SUBSIDIARIES



Notes to Consolidated Financial Statements(Continued)



Advantest capitalizes certain costs incurred to purchase or develop software for internal-use. Costs
incurred to develop software for internal-use are expensed as incurred during the preliminary project stage, which includes costs for making strategic decisions about the project, determining performance and system requirements and vendor
demonstration cost. Costs incurred subsequent to the preliminary project stage through implementation are capitalized. Advantest also expenses costs incurred for internal-use software projects in the post implementation stage such as costs for
training and maintenance.



Costs incurred to develop software
to be included with and sold as part of the Companys Semiconductor Test Systems are capitalized subsequent to the attainment of technological feasibility in accordance with the provisions of SFAS No. 86, Accounting for the Costs of
Computer Software to Be Sold, Leased, or Otherwise Marketed. To date, costs incurred subsequent to the attainment of technological feasibility have been insignificant and, therefore, have been charged directly to expense. Costs incurred prior
to reaching technological feasibility are expensed as incurred.



The cost of software is amortized on a straight-line basis over the estimated useful life, which is generally five years. The cost of computer software under capital leases is amortized straight-line over the lease term.



Business combinations are accounted for using the purchase method in
accordance with SFAS No. 141, Business Combinations. SFAS No. 141 establishes certain criteria for the recognition of intangible assets separately from goodwill. Under SFAS No. 142, Goodwill and Other Intangible Assets,
goodwill is no longer amortized, but instead is tested for impairment at least annually. Intangible assets with definite useful lives are amortized over their respective estimated useful lives and reviewed for impairment in accordance with SFAS No.
144, Accounting for the Impairment or Disposal of Long-Lived Assets. Any recognized intangible assets determined to have an indefinite useful life are not amortized, but instead are tested for impairment until its life is determined to
be no longer indefinite.



Advantest performs its annual
impairment test at the end of each year. Advantest completed its annual impairment test at the end of the years ended March 31, 2004 and 2005, with no indication of impairment identified.



(k) Impairment of Long-Lived Assets



Advantest evaluates the impairment of long-lived assets in accordance with the provisions of SFAS No. 144. SFAS No. 144
requires that long-lived assets and certain identifiable intangibles with definite useful lives be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to
be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets.



For the year ended March 31, 2004, one of the former independent cash flow-generating units, the measuring instruments assets group reported
operating losses for two consecutive years, and future operating results of the assets group was not expected to be profitable, due to the customers continuously inactive industries such as wireless communications. Since the carrying amount of
the assets group was higher than the undiscounted net cash flows expected to result from the use and eventual disposition of the assets group, Advantest adjusted its carrying amount to the recoverable amount. The recoverable amount was based on the
observable market price and Advantests cash flow analysis. Total recognized impairment loss was ¥3,030 million and is included in selling, general and administrative expenses for the year ended March 31, 2004. The impairment loss consisted
of ¥1,226 million from buildings, ¥175 million from machinery and equipment, ¥683 million from furniture and fixtures, ¥681 million from software, and ¥265 million from other assets.

(l) Accrued Warranty Expenses



Advantests products are generally subject to warranty, and Advantest
provides an allowance for such estimated costs when product revenue is recognized. To provide for future repairs and support during warranty periods, estimated repair and support expenses over the warranty period are accrued based on the historical
ratio of actual repair and support expenses to corresponding sales.



(m) Accrued Pension and Severance Cost



The Company and certain of its domestic subsidiaries have retirement and severance defined benefit plans covering substantially all of their employees. The benefits are based on years of service and the employees compensation and vest
after one year of service. Prior service cost that results from amendments to the plan is amortized over the average remaining service period of the employees expected to receive benefits. Unrecognized net gain and loss is also amortized over the
average remaining service period of the employees expected to receive benefits. See Note (17) to the consolidated financial statements for further discussion.



(n) Revenue Recognition



In accordance with the guidance provided by the Securities and Exchange Commissions Staff Accounting Bulletin No. 104, Revenue
Recognition, Advantest recognizes revenue when there is persuasive evidence of an arrangement, title and risk of loss have passed, delivery has occurred or the services have been rendered, the sales price is fixed or determinable and
collection of the related receivable is reasonably assured.



Revenue from Sales of Products



Revenue from
sales of products which require installation work is recognized when the related installation work is completed. The revenue recognized upon completion of installation is limited to the amount that is payable based on customer acceptance. Revenue
from sales of products and component which do not require installation work by Advantest is recognized upon shipment if the terms of the sale are free on board (FOB) shipping point or upon delivery if the terms are FOB destination which
coincide with the passage of title and risk of loss.



For
equipment sales involving software that is more than incidental to the product, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collection of the related
receivable is probable in accordance with American Institute of Certified Public Accountant (AICPA) Statement of Position (SOP) No. 97-2, Software Revenue Recognition, as amended by SOP No. 98-9,
Modification of SOP 97-2, Software Revenue Recognition, With Respect to Certain Transactions. Revenue for the separate elements is only recognized when the functionality of the undelivered element is not essential to the delivered
element.



Revenue from Long-term Service contracts



Revenue from fixed-price, long-term service contracts is
recognized on the straight-line basis over the contract term.



Operating lease



Revenue from operating leases
is primarily recognized on the straight-line basis over the lease term.

Multiple deliverables



Multiple Deliverables are accounted for under the Emerging Issues Task Force Issue No. 00-21 (EITF 00-21),
Revenue Arrangements with Multiple Deliverables. EITF 00-21 addresses how to determine whether an arrangement involving multiple deliverables contains more than one unit of accounting.



Advantest enters into certain revenue arrangements with multiple
deliverables, which include combination of equipment, installation and warranty services. As those installation or warranty services are not interchangeable to be provided by Advantest or other parties and as fair values of those services are not
determinable, these elements are not considered to qualify for separate accounting under EITF 00-21 and accordingly Advantest treats them as a single unit of accounting. Advantest adopted the provisions of EITF 00-21 for the transactions entered
into on and after July 1, 2003. The effect on Advantests consolidated financial statements from the adoption of such provisions was insignificant.



(o) Shipping and Handling Costs



Shipping and handling costs totaled ¥774 million, ¥1,011 million and ¥1,329 million ($12,375 thousand) for the years ended March 31, 2003,
2004 and 2005, respectively, and are included in selling, general and administrative expenses in the consolidated statements of operations.



(p) Research and Development



Research and development costs totaled ¥23,615 million, ¥21,637 million and ¥26,280 million ($244,716 thousand) for the years ended March 31,
2003, 2004 and 2005, respectively, and are expensed as incurred.



(q) Advertising Costs



Advertising
costs totaled ¥428 million, ¥384 million and ¥798 million ($7,431 thousand) for the years ended March 31, 2003, 2004 and 2005, respectively, and are expensed as incurred.



(r) Stock-Based Compensation



Prior to April 1, 2004, the Company accounted for stock-based compensation plans by applying the intrinsic value-based
method of accounting under the recognition and measurement provisions of APB Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations, as permitted by SFAS No. 123, Accounting for Stock-Based
Compensation. No stock-based employee compensation cost was recognized in the statement of operations for the years ended March 31, 2003 and 2004. Effective April 1, 2004, the Company early adopted the fair value recognition provisions of SFAS
No. 123 (revised 2004) (SFAS No. 123R), Share Based Payment, using the modified-retrospective method. The fair value of the options is estimated using a Black Scholes option pricing model and amortized to expense over the
options vesting periods.

(s) Income Taxes



Income taxes are accounted for under the asset and
liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and
operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The
effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Advantest records a valuation allowance to reduce the deferred tax assets to the amount that is more
likely than not realizable.



(t) Net Income (Loss) per
Share



Basic net income (loss) per share is calculated
by dividing net income (loss) by the weighted average number of shares outstanding during the year. Diluted net income per share is calculated by dividing net income by the sum of the weighted average number of shares plus additional shares that
would have been outstanding if potential dilutive shares had been issued for granted stock options and warrants.

Notes to Consolidated Financial Statements(Continued)



At March, 31, 2003, 2004 and 2005, Advantest had outstanding stock options and warrants exercisable
into 1,113,800, 329,500 and 7,000 shares of common stock, respectively, which could potentially dilute net income per share in future periods.



(u) Translation of Foreign Financial Statements



Foreign currency financial statements have been translated in accordance with SFAS No. 52, Foreign Currency Translation. Under SFAS No. 52,
assets and liabilities of non-Japanese subsidiaries, which have a functional currency other than the Japanese yen, are translated at the rate of exchange on the balance sheet date. Revenue and expense accounts are translated at the average rate of
exchange in effect during the year. Resulting translation adjustments are included as a component of accumulated other comprehensive income (loss).



(v) Foreign Currency Transactions



Assets and liabilities denominated in foreign currencies at the balance sheet date are translated at the applicable current rate prevailing at that date.
All revenue and expenses associated with foreign currencies are converted at the rate of exchange prevailing when such transactions occur. The resulting exchange gains or losses are reflected in other income (expense) in the accompanying
consolidated statements of operations.



(w) Use of
Estimates



Management of Advantest has made a number
of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statement and the reported amounts of revenues and expenses during the
period to prepare these consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. Significant items subject to such estimates and assumptions include valuation allowances for trade
receivables, inventories and deferred tax assets, various accruals such as accrued warranty expenses, and assets and obligations related to employees retirement and severance plans. Actual results could differ from those estimates.



(x) New Accounting Standards



In March 2004, the Emerging Issues Task Force reached a consensus on Issue
No.03-1 (EITF 03-1), The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments. EITF 03-1 provides guidance on other-than-temporary impairment models for marketable debt and equity securities
accounted for under Statement of Financial Accounting Standards (SFAS) No.115, Accounting for Certain Investments in Debt and Equity Securities (SFAS 115), and non-marketable equity securities accounted for under
the cost method. The EITF developed a basic three-step model to evaluate whether an investment is other-than-temporarily impaired. The Financial Accounting Standards Board (FASB) issued FASB Staff Position EITF 03-1-1 in September
2004 which delayed the effective date of the recognition and measurement provisions of EITF 03-1. The adoption of EITF 03-1 is not expected to have a material effect on Advantests consolidated results of operations and financial position.



In November 2004, the FASB issued SFAS No.151, Inventory
Costs-an amendment of ARB No. 43, Chapter 4 (SFAS 151). SFAS151 amends the guidance in ARB No.43, Chapter 4, Inventory Pricing, to clarify the accounting for abnormal amounts of idle facility expense, freight, handling
costs, and wasted material (spoilage). Among other provisions, the new rule requires that items such as idle facility expense, excessive spoilage, double freight, and rehandling costs be recognized as current period charges regardless of whether
they meet the criterion of so abnormal as stated in ARB No. 43. Additionally, SFAS 151 requires that the allocation

of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS 151 is effective for fiscal years
beginning after June 15, 2005 and is required to be adopted by Advantest in the first quarter beginning April 1, 2006. Advantest is currently evaluating the effect that the adoption of SFAS 151 will have on its consolidated results of operations and
financial condition.



In December 2004, the FASB issued SFAS
No.153, Exchange of Nonmonetary Assets-an amendment of APB Opinion No.29 (SFAS 153) eliminates the exception from fair value measurement for nonmonetary exchanges of similar productive assets in paragraph 21(b) of APB Opinion
No.29, Accounting for Nonmonetary Transactions, and replaces it with an exception for exchanges that do not have commercial substance. SFAS 153 specifies that a nonmonetary exchange has commercial substance if the future cash flows of
the entity are expected to change significantly as a result of the exchange. SFAS 153 is effective for the fiscal periods beginning after June 15, 2005 and is required to be adopted by Advantest in the first quarter beginning April 1, 2006.
Advantest is currently evaluating the effect that the adoption of SFAS 153 will have on its consolidated results of operations and financial condition.



(y) Reclassifications



Certain reclassifications have been made to the prior years consolidated financial statements to conform with the presentation used for the year
ended March 31, 2005.



(2) U.S. Dollar Amounts



U.S. dollar amounts presented in the consolidated financial statements and
related notes are included solely for the convenience of the reader. These translations should not be construed as representations as to what the yen amounts actually represent, or have been or could be converted into, U.S. dollars. For this
purpose, the rate of ¥107.39 per U.S.$1, the approximate current exchange rate at March 31, 2005, was used for the translation of the accompanying financial results of Advantest as of and for the year ended March 31, 2005.

AND SUBSIDIARIES



Notes to Consolidated Financial Statements(Continued)



Gross realized gains and losses based on the averaged cost method are included in other income
(expense) in the consolidated statements of operations, and other in net cash provided by operating activities in the consolidated statements of cash flows.



Proceeds from the sale of available-for-sales equity securities for the years ended March 31, 2003, 2004 and 2005 were nil,
¥323 million and ¥1,428 million ($13,297 thousand), respectively.



As of March 31 2005, there was no available-for-sale equity security in an unrealized loss position.



Advantest maintains non-marketable investment securities, which are recorded at cost. The carrying amounts of non-marketable investment securities were
¥3,641 million and ¥1,444 million ($13,447 thousand) at March 31, 2004 and 2005, respectively. Investments with an aggregate cost of ¥1,444 million ($13,447 thousand) did not have indicators of impairment and Advantest did not identify
any events or changes in circumstances that might have had significant adverse effect on the fair value of those investments.



(9) Derivative Financial Instruments



Derivative financial instruments are utilized by Advantest primarily to reduce foreign currency exchange risk. Advantest does not hold or issue derivative
financial instruments for trading purposes. Advantest generally does not require or place collateral for these derivative financial instruments.



Derivative financial instruments contain an element of risk in the event the counterparties are unable to meet the terms of the agreements. However,
Advantest minimizes risk exposure by limiting the counterparties to major international banks and financial institutions meeting established credit guidelines. Management of Advantest does not expect any counterparty to default on its obligations
and, therefore, does not expect to incur any losses due to counterparty default on its obligations.



Advantest had foreign exchange forward contracts to exchange currencies among Japanese yen, U.S. dollars and Euro at March 31, 2004 and 2005. The notional
amounts of these contracts were ¥8,736 million at March 31, 2004 and ¥7,603 million ($70,798 thousand) at March 31, 2005. The fair values of these contracts at March 31, 2004 and 2005 are shown in Note (10) to the consolidated financial
statements. These contracts do not qualify for hedge accounting since they do not meet the hedging criteria specified by SFAS No. 133. Changes in the fair value are recognized in earnings under the caption of other income (expense).

(10) Fair Value of Financial Instruments



The following table presents the carrying amounts and estimated fair values of Advantests financial instruments at
March 31, 2004 and 2005, except for cash and cash equivalents, trade receivables, other current assets, trade accounts payable and accrued expenses for which fair value approximate their carrying amounts. Fair value estimates are made at a specific
point in time based on relevant market information and information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgement and, therefore, cannot be determined with
precision. Changes in assumptions could significantly affect the estimates.

The carrying amounts
shown in the table are included in the consolidated balance sheets under the indicated captions. And the carrying amounts of foreign exchange forward contracts are included in other current assets and other current liabilities.



The following methods and assumptions were used to estimate the fair value of
each class of financial instruments:



Cash and cash
equivalents, trade receivables, other current assets, trade accounts payable, and accrued expenses (nonderivatives): The carrying amounts approximate fair value because of the short maturity of these instruments.



Investment securities: The fair values of equity investments are based
on quoted market prices at the reporting date for those investments. It was not practicable to estimate the fair value of nonpublic companies; those investments are carried at cost.

Long-term debt: The fair value of long-term debt is estimated by discounting future cash flows
of each instrument at rates currently offered to Advantest for similar debt instruments of comparable maturities by financial institutions.



Foreign exchange forward contracts: The fair value of foreign exchange forward contracts are estimated by obtaining quotes from financial
institution.

Unsecured 0.88% bonds
were issued with detachable warrants in connection with one of Advantests stock-based compensation plans. As described in Note (16) to the consolidated financial statements, upon issuance of each bond, the Company purchased all detachable
warrants from the underwriter and distributed such warrants to the directors and selected employees of the Company and its subsidiaries. No gain or loss was recognized on the sale and purchase of the warrants. For financial reporting purposes, these
transactions were accounted for as the issuance of debt to third parties and separately as the issuance of warrants to directors and employees.



At March 31, 2005, property, plant and equipment with a carrying amount of ¥393 million ($3,660 thousand) was pledged as collateral for certain debt
obligations in the amount of ¥24 million ($223 thousand).

The Company and its
domestic subsidiaries are subject to a corporate tax of 30%, an inhabitant tax of between 18.1% and 20.7% and a deductible business tax of between 7.2% and 10.1%, which in the aggregate resulted in a statutory income tax rate of approximately 40%
for the year ended March 31, 2005. Amendments to the Japanese tax regulations were enacted on March 24, 2003. As a result of these amendments, the statutory income tax rate was reduced from approximately 42% to 40% effective from the year beginning
April 1, 2004. Consequently, the statutory tax rate was to be lowered to approximately 40% applicable for deferred tax assets and liabilities expected to be settled or realized subsequent to April 1, 2004. The adjustment of deferred tax assets and
liabilities for this change in the tax rate was ¥143 million and reflected in the consolidated statements of operations for the year ended March 31, 2004.



A reconciliation of the Japanese statutory income tax rate and the effective income tax rate as a percentage of income (loss) before income taxes is as
follows:

The net changes in the
valuation allowance for the years ended March 31, 2003, 2004 and 2005 were an increase of ¥1,371 million, ¥509 million and ¥876 million ($8,157 thousand), respectively.



Net operating loss carryforwards utilized during the years ended March 31, 2003, 2004 and 2005 were ¥633 million,
¥24,510 million and ¥31,132 million ($289,897 thousand), respectively.



At March 31, 2005, Advantest had net operating loss carried forwards for income tax purposes of approximately ¥1,102 million ($10,262 thousand) which are available to reduce future income taxes, if any. These
operating losses will expire starting from the year ending March 31, 2006 through the year ending March 31, 2010.



Management of Advantest intends to reinvest certain undistributed earnings of the Companys foreign subsidiaries for an indefinite period of time. As
a result, no provision for income taxes has been made on undistributed earnings of these subsidiaries not expected to be remitted in the foreseeable future, aggregating ¥52,022 million ($484,421 thousand) at March 31, 2005. The related deferred
tax liability would have been ¥7,501 million ($69,848 thousand) at March 31, 2005.



In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable
income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. At
March 31, 2005, Advantest has recorded on its consolidated balance sheet, net deferred tax assets of ¥21,572 million ($200,875 thousand). Based upon projections for future taxable income over the periods in which the deferred tax assets are
deductible including managements expectations of future semiconductor market and semiconductor and component test systems market prospects and other factors, management believes it is more likely than not that Advantest will realize the
benefits of these deductible differences, net of the existing valuation allowance, at March 31, 2005. The amount of the deferred tax assets considered realizable, however, could be reduced in the near term if estimates of future taxable income are
reduced and the effect on Advantests consolidated financial position and results of operations could be significant.

Notes to Consolidated Financial Statements(Continued)



The Company and its domestic subsidiaries also have a contributory defined benefit retirement and
severance plan covering substantially all employees. Benefits payable under the plan is based on employee earnings and years of service. The contributory plan mainly represents the Employees Pension Fund (EPF) plan, composed of the
substitutional portions based on the pay-related part of the old age pension benefits prescribed by the Welfare Pension Insurance Law in Japan and the corporate portions based on contributory defined benefit pension arrangements established at the
discretion of the Company and its subsidiaries.



In January
2003, the EITF reached a final consensus on EITF 03-2, Accounting for the Transfer to the Japanese Government of the Substitutional Portion of Employee Pension Fund Liabilities. EITF 03-2 addresses accounting for a transfer to the
Japanese government of the substitutional portion of an EPF plan. EITF 03-2 requires employers to account for the entire separation process of the substitutional portion from the EPF upon completion of the transfer to the government of the
substitutional portion of the benefit obligation and related plan assets as the culmination of a series of steps in a single settlement transaction. Under this approach, the difference between the fair value of the obligation and the assets required
to be transferred to the government should be accounted for and separately disclosed as a subsidy. On October 1, 2004, the Company and certain of its consolidated domestic subsidiaries received approval from the Minister of Health and Labor to
return the substitutional portion of its Employees Pension Fund plans for the prior employees services under the transfer of its Employees Pension Fund plans to the defined benefit corporate pension plan, and made the payment of
the amount pertinent to the return (minimum liability reserve) to the national treasury on February 24, 2005. Advantest accounted for the elimination of future benefits and relief of past obligations with the transfer of assets as the culmination of
a series of steps in a single settlement transaction and recognized a net gain of ¥3,317 million ($30,887 thousand) through these transactions for the year ended March 31, 2005, which is included in selling, general and administrative expenses
and consists of ¥6,116 million ($56,951 thousand) of a subsidy from the government, calculated as the difference between the obligation settled and the plan assets transferred to the government, and ¥2,799 million ($26,064 thousand) of a
settlement loss on recognition of related unrecognized actuarial loss.



Effective April 1, 2005, the Company and its domestic subsidiaries amended their severance indemnity plan by introducing a point-based benefits system, under which benefits are calculated based on accumulated points allocated to
employees each year according to their job classification and their performance.



Effective April 1, 2005, the Company and its domestic subsidiaries amended their defined benefit pension plans, and a cash balance pension plan was established. Under a cash balance pension plan, the benefits are
calculated based on accumulated points allocated to employees each year according to their job classification and their performance with a certain interest rate calculated based on the upper and lower limit of a market interest rate. These
amendments resulted in a decrease in the Companys projected benefit obligation.



In December 2003, the FASB issued SFAS No. 132 (revised 2003) (SFAS No. 132R), Employers Disclosures about Pensions and Other Postretirement Benefits. SFAS No. 132R revises and prescribes
employers disclosures about pension plans and other postretirement benefit plans; it does not change the measurement or recognition of those plans. SFAS No. 132R retains the disclosure requirements contained in the original SFAS No. 132. It
also requires additional disclosures about the assets, obligations, cash flows, and net periodic benefit cost of defined benefit pension plans and other postretirement benefit plans.

certain of its securities into cash in acknowledgement of the pending separation of the remaining substitutional portion (that is, the benefit obligation related to past services) by the year ended March 31, 2004.



Advantests investment policies are designed to ensure adequate plan
assets are available to provide future payments of pension benefits to eligible participants by attaining necessary long-term total returns on plan assets. Taking into consideration the expected returns, associated risks and correlations of returns
between asset categories in plan assets, Advantest determines an optimal combination of equity and debt securities as Policy Asset Allocation (PAA). Plan assets are invested in individual equity and debt securities according to PAA with
mid-term to long-term viewpoint, which is revised periodically to the extent considered necessary to achieve the expected long-term rate of return on plan assets.



Cash flows:



Advantest expects to contribute ¥2,125 million ($19,788 thousand) to its domestic defined benefit plans during the year ending March 31, 2006.

Notes to Consolidated Financial Statements(Continued)



Adjustments to operating income (loss) in Corporate principally represent corporate general and
administrative expenses and research and development expenses related to fundamental research activities that are not allocated to operating segments.



The operating income in the business segment information for the year ended March 31, 2005 do not match the consolidated statements of operations as the
business segment information does not include a net gain on settlement of substitutional portions of EPF of ¥3,317 million ($30,887 thousand) and the stock option cost of ¥2,290 million ($21,324 thousand). Profit and loss from these are not
included in managements analysis of results.



As
discussed in Note 1 (k) to the consolidated financial statements, an impairment charge of ¥3,030 million for long-lived assets was included in the operating income (loss) of semiconductor and component test system and services, support and
others for the year ended March 31, 2004.



Additions to
long-lived assets included in Corporate consist of purchases of software and fixed assets for general corporate use.



Total assets included in Corporate consist of cash and cash equivalents, assets for general corporate use and assets used for fundamental research
activities, which are not allocated to reportable segments.



One customer and its related entities mainly in the semiconductor and component test system segment and the mechatronics system segment accounted for approximately 12%, 12% and 10% of total consolidated net sales for the years ended March
31, 2003, 2004 and 2005. Another customer accounted for approximately 15% for the years ended March 31, 2005.

(23) Commitments and Contingent Liabilities



In November 2002, the FASB issued FIN 45, Guarantors Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an interpretation of SFAS No. 5, 57, and
107 and rescission of FASB Interpretation No. 34. FIN 45 requires that a liability be recorded in the guarantors balance sheet upon issuance of a guarantee. The initial recognition and measurement provisions of FIN 45 were applicable to
guarantees issued or modified after December 31, 2002.



Advantest provides guarantees to third parties mainly for customers lease obligations. Advantest would be required to satisfy customers lease obligations in the event of default. The maximum amount of undiscounted payments is ¥569
million and ¥387 million ($3,604 thousand) at March 31, 2004 and 2005, respectively. The guarantees are collateralized by the leased equipment. At March 31, 2005, Advantest has not accrued any obligation with respect to such guarantees as it
estimates the fair value of its obligations to be insignificant.



Advantest is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on Advantests
consolidated financial position, results of operations, or cash flows.
