             Advantest Corporation - Consolidated (FY 2005 Interim)

1.      Management Policy

Advantest's Basic Management Policy
- -----------------------------------

         Advantest believes that its philosophy of management is to support
leading-edge technology at its forefront. Its basic management policy consists
of the following elements: increasing corporate value, improving shareholder and
customer satisfaction and achieving excellence.

Business Strategy
- -----------------

         While maintaining "Measurements" as our core competence, Advantest
intends to improve its corporate value by establishing an operation and finance
structure that responds timely to changes in the global market, and also aims to
increase market share by introducing fine products that will inspire the market
demands of the next generation. To achieve these objectives, Advantest is driven
to further strengthen its product development operations and improve production
efficiency by selectively focusing on certain businesses, while strengthening
its overseas operations and support system in the U.S., Europe and Asia.

         Further, Advantest seeks to increase the level of customer satisfaction
by maximizing the functions of our test systems by providing them with a
solution for businesses to improve business efficiency.

         On October 1, 2005, Advantest launched a company-wide initiative called
"Activate 21". Not only does this initiative, which is set to end with FY2008,
continue with the improvements and reforms initiated with "Initiative 21", which
ended with the previous fiscal year, but also implements reforms that emphasizes
cost and efficiency from a global perspective.

Target Financial Index
- ----------------------

         Advantest applies the "AVA" (Advantest Value Added), a financial index
incorporating the concept of EVA(R) (Economic Value Added) *(1), as a
significant performance indicator, along with profit margin, ROE and cash flows,
to measure its business performance. Specifically, Advantest will continue to
set the minimum return-on-investment ratio ("hurdle rate") for evaluating AVA at
8% and a mid-term target at 12% with an aim to increase corporate value and
shareholder value.

       *(1)"EVA(R)" is a registered trademark of Stern Stewart & Co.

Basic Policy on Distribution of Profits
- ---------------------------------------

         Advantest believes that shareholder value is premised on the
realization of long-term and continued growth in corporate value.

         With respect to the distribution of profits, Advantest has adopted a
policy of maintaining consistent dividend payouts after taking into
consideration of business performance and financial condition.

         Retained profits are research and development, streamlining efforts,
overseas expansion and investing in new businesses to enable the strengthening
of its business position and creation of corporate value.

Advantest's Views and Policies on Lowering its Investment Unit
- --------------------------------------------------------------

                                     - 3 -



         As part of its capital policy, Advantest has long recognized the
importance of increasing the market liquidity of its shares, promoting long-term
and stable holding of its shares among investors and expanding its investor
base. Back in August 1995, the company reduced the minimum investment unit for
its shares from 1,000 to 100 shares.

         As Advantest considers the current liquidity level of its shares to be
sufficient and expects any further reduction of investment unit to require
significant costs, it is cautious about implementing any further reductions and
will do so only after careful consideration of prevailing market conditions,
business performance, share prices and other factors.

Advantest's Basic View on Corporate Governance; Status of Implementation of
- ---------------------------------------------------------------------------
Corporate Governance
- --------------------
[Advantest's Basic View on Corporate Governance]

         Advantest intends to strengthen its global competitiveness by enhancing
information disclosure to all stakeholders, including its investors
(shareholders) and customers.
[Status of Implementation of Corporate Governance]

(1)  Functions of the Company's Organization

         In order to ensure timely response to rapid changes in the business
environment and to strengthen corporate governance, Advantest implemented the
executive officer's structure and separates its decision-making functions and
operational function.

         As the decision making body of the operation, the board of directors
set the group's business policies and purpose, monitor and manage the operation
of business, and delegate significant authority for executing operations
speedily and efficiently.

         Advantest adopts a Board of Corporate Auditors system, and the Board of
Corporate Auditors is comprised of 4 auditors (of which 2 are external
auditors). Each auditor, based on the policies and plans adopted by the Board of
Corporate Auditors, audit the board's fulfillment of its duties by attending
significant meetings such as the Board of Directors meeting and investigating
the company's business and finance.

(2)  Status of the Internal Controls System, Risk Management System and
     Corporate Audit

         In order to strengthen the corporate structure for Corporate Social
Responsibility, Advantest has implemented the "CSR (Corporate Social
Responsibility) Committee" and placed under it the "Disclosure Committee",
"Internal Controls Committee", "Environmental Policy Supervisory Committee",
"Information Security Committee", "Human Rights Committee", "Human Resource
Complaints Processing Committee", and "Behavior Norms Committee" that are
expanding its activities. In particular, the "Internal Controls Committee" that
was implemented in order to strengthen the Internal Controls process and risk
management structure is taking measures to establish the three objectives of
internal controls that are "Reliability of Financial Reports", "Compliance with
the Law" and "Business Effectiveness and Efficiency". Also, the Auditing Group
with an internal audit responsibility monitors the internal controls procedures
and its application on a daily basis and identifies comments and advises
improvement as part of operational audit. Furthermore, the Auditing Group, Board
of Corporate Auditors and outside audit firm coordinate amongst each other,
exchange information regarding audit schedule, audit status and internal
controls, and conduct meetings periodically and whenever necessary.



                                     - 4 -


         Advantest's basic principle is to conduct business with high ethical
standards, integrity and social justice. As such, Advantest has developed the
"Advantest Behavior Norms" and in the "Code of Ethics for Officers", Advantest
clarified that the officers will act with integrity and ethically. In April
2005, in response to applicable regulations and to achieve a higher level of
consciousness about ethical value, the "Advantest Behavior of Norms" was
revised, and the "Corporate Ethics Helpline" was established to handle comments,
reports and to advise regarding accounting, internal controls, and audit. Also
the "Behavior Norms Committee" was established to strengthen compliance.

Matters Relating to Parent Companies
- ------------------------------------

         Advantest does not have a parent company as of the end of this interim
period.


2.   Business Results and Financial Condition

(1) Business Results

Interim Fiscal Period Results
- -----------------------------

         During this interim fiscal period, although inventory control in the IT
related industries continued during the first half of this interim period,
Advantest's operating environment was favorable, as stimulated by the strong
demand for consumer digital products and personal computers, particularly
notebooks computers, and due to the trend towards recovery in capital
expenditures by the semiconductor industry. In particular, the increased demand
for portable audio players worldwide and the spread of flat screen television
led to an increase in semiconductor sale. In addition, the trend towards a
weaker yen in currency exchange was a positive factor.

         Under this environment, Advantest made concentrated efforts to increase
orders input received and expand sales through the timely introduction of new
products that meet customers' demands. Advantest continued to make efforts to
improve productivity and profitability through reorganization of its
manufacturing operations, as well as by implementing measures to further reduce
lead-time and to reduce costs.

         As a result of the above, as compared to the corresponding interim
period of the previous fiscal year, during which Advantest achieved the highest
net sales of any interim period, orders input received decreased by 2.9% to
(Y)121.6 billion, net sales decreased by 26.9% to (Y)107.1 billion, net income
before income taxes decreased by 46.8% to (Y)24.5 billion, and interim net
income decreased by 47.5% to (Y)14.6 billion. As compared to the second half of
the previous fiscal year, however, Advantest returned to an increase in profit
and an increase in income as orders input received increased by 18.9%, net sales
increased by 15.3%, net income before income taxes increased by 55.8%, and
interim net income increased by 42.4% indicating a recovery trend. Overseas
sales as a percentage of total sales were 67.7%, as compared with 74.3% in the
corresponding interim period of the previous fiscal year.


Condition of Business by Segment
(Semiconductor and Component Test System Segment)

         In this segment, as inventory adjustment by IT related industries
approached completion, and demand for new test systems increased as a result of
increased production of semiconductors.



                                     - 5 -


         In the memory test system market, due to increased production of NAND
type flash memory used in products such as portable audio players, sales in
flash memory test systems remained strong domestically and overseas. With
respect to DRAM test systems, sales remained strong due to respective sales in
high-speed memory semiconductor test system for DDR2, a high-speed,
high-efficiency and memory test systems for DRAM for consumer digital products
in certain geographic areas.

         In the market of non-memory semiconductor test system, stimulated by
strong sales in personal computers, sales of the T2000, a test system compatible
with OPENSTAR(R)*(2), was very strong. In addition, sales in SoC semiconductor
test system for game devices and devices used in consumer digital products and
sales of test systems for LCD driver IC remained positive domestically and in
Taiwan. With respect to other test systems, sales of test systems for CCD, used
in digital cameras, and the test systems for semiconductors related to
automobiles remained steady.


         As a result of the above, orders input received was (Y)93.7 billion
(2.5% decrease in comparison to the corresponding interim period of the previous
fiscal year), sales was (Y)80.8 billion (28.6% decrease) and operating income
was (Y)21.0 billion (44.4% decrease).

(Mechatronics System Segment)

         Stimulated by the positive sales of the T2000 and non-memory test
systems for digital consumer products, sales in non-memory semiconductor test
handlers remained steady. Sales of memory test handlers was weaker due to a lag
in the sales of DRAM test systems. On the other hand, sales of device interface
products was steady, due to the increased demand for flash memory semiconductor
and semiconductor for SoC.

         As a result, orders input received was (Y)21.7 billion (12.1% decrease
in comparison with the corresponding interim period of the previous fiscal
year), sales was (Y)20.5 billion (27.1% decrease) and operating income was
(Y)4.6 billion (53.9% decrease).

(Services, Support and Others Segment)

         In this segment, orders input received was (Y)9.1 billion (9.7%
decrease in comparison with the corresponding interim period of the previous
fiscal year), sales was (Y)8.5 billion (21.5% decrease) and operating income
was (Y)1.9 billion (154.9% increase).

     *(2)OPENSTAR(R): The name of an open architecture standard published by the
     STC (Semiconductor Testing Consortium, Inc.). OPENSTAR(R) is a registered
     trademark or a trademark of STC in the United States, Japan and other
     countries.


Distribution of Profits

         As described above, sales in this interim fiscal period indicate a
trend towards recovery. Due to potential uncertainties affecting its operating
environment, however, Advantest decided, based on its profit distribution policy
described above to distribute an interim dividend of (Y)25 per share.


Prospects for the Fiscal Year
- -----------------------------



                                     - 6 -


         Regarding its operating environment in the upcoming fiscal year,
Advantest expects to see expanded volume and application of flash memory used
for digital cameras or portable audio players, and a continuing increase in the
demand for non-memory semiconductors for consumer digital products. With respect
to DRAM, Advantest expects a rapid shift to DDR2 for servers and high-tech
personal computers. Furthermore, continued active capital expenditures relating
to 300mm wafers by the semiconductor manufactures and foundries are expected.

         On the other hand, restrained capital expenditures as a result of poor
supply and demand balance, an issue unique to the semiconductor market,
increased prices of raw materials such as oil, currency risk attributable to a
strong yen, and strengthened downward pressure on prices as a result of the
above-mentioned factors may affect our results.

         In order to respond to these conditions, Advantest plans to continue
its efforts to increase orders input received and expand sales through the
timely introduction of new products that meets customers' needs by strengthening
marketing and development structure. To further strengthen its cost
competitiveness, Advantest will make continued efforts to improve profitability
by reviewing its operational process company wide and improving manufacturing
efficiency.

         As a result of the above, Advantest's current estimates for the full
year are as follows:

Notes to the Interim Consolidated Financial Statements

(Note 1) Accounting Principles, Procedures and the Presentation of the Interim
Consolidated Financial Statements

(a)  Terminology, Form and Method of Preparation of the Interim Consolidated
     Financial Statements

     Advantest prepares these interim consolidated financial statements in
     accordance with the accounting principles, procedures, terminology, form
     and mode of preparation required in the U.S. in connection with its
     issuance of American Depository Shares as established under Accounting
     Research Bulletins ("ARB"), Accounting Principles Board ("APB") statements,
     Statements of Financial Accounting Standards ("SFAS") and other relevant
     sources (collectively "U.S. GAAP"). However, Advantest Corporation and its
     consolidated subsidiaries prepare their unconsolidated financial statements
     in accordance with accounting principles generally accepted in 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 U.S.

(b)  The Preparation of Consolidated Financial Statements and Registration with
     the U.S. Securities and Exchange Commission

     Advantest Corporation began listing on the New York Stock Exchange on
     September 17, 2001 (local time) by means of an issuance of American
     Depository Shares, and is registered with the U.S. Securities and Exchange
     Commission on Form 20-F (equivalent to the Annual Securities Report in
     Japan) since FY2001. In connection with the registration on Form 20-F,
     Advantest prepares its consolidated financial statements in accordance with
     U.S. GAAP.

(c)  Scope of Consolidation and Application of the Equity Method

     Advantest's interim consolidated financial statements include financial
     statements of Advantest Corporation and its majority-owned subsidiaries.
     All significant intercompany balances and transactions have been eliminated
     in consolidation.

     The following table sets forth the number of consolidated subsidiaries and

(Note 2) Summary of Significant Accounting Policies and Practices

         There was no change in accounting policies and practices.

(Note 3) Restatement of the Interim Consolidated Financial Statements for the
Previous Interim Period

         Advantest measures its stock-based compensation cost based on the fair
value method as defined in SFAS No.123 (revised 2004) ("No.123R") Share-Based
Payment, and recognized such cost as an expense in the statements of income.
Advantest has retrospectively applied this accounting method effective April 1,
2004 by using the "modified retrospective" approach prescribed by the said
statement in the fiscal year ended March 2005.

         The SFAS No. 123R Share-Based Payment was released after Advantest
filed its interim report. For this reason, until the previous interim
consolidated period, Advantest accounted for its stock-based compensation cost
based on the intrinsic value method prescribed by Accounting Principle Board
Opinion No.25, "Accounting for Stock Issued to Employees" and related
interpretations as allowed under the SFAS No.123 "Accounting for Stock-Based
Compensation". Advantest had not recognized its stock-based compensation cost in
the statements of income for the previous interim fiscal period. As such, in
connection with the retrospective application of the SFAS No.123R Share-Based
Payment effective April 1, 2004, the interim consolidated financial statements
for the previous interim period have been restated.

         Due to the restatement made to the interim consolidated financial
statements for the previous interim period, selling, general and administrative
expense increased by (Y)759 million. Operating income, net income before income
taxes and interim net income for the previous decreased by the same amount.
Basic interim net income per share decreased by (Y)7.72, and diluted net income
per share decreased by (Y)7.70. Capital surplus increased and retained earnings
decreased by (Y)759 million in the interim consolidated balance sheet at the end
of the previous interim. Comprehensive income for the previous interim period
decreased by the same amount accordingly. Due to a decrease of (Y)759 million in
interim net income, the interim consolidated cash flow statement for the
previous interim period has been restated as well.

         The impacts on the segment information have been discussed in the notes
to the segment information.

         A fair value for stock options is calculated based on the Black-Scholes
Option Pricing Model.

         Stock-based compensation expenses recognized are (Y)2,290 million in
FY 2004, and (Y)755 million in FY 2005 Interim.

         A weighted average fair value per share for stock options that were
granted in FY 2004 Interim and FY 2005 Interim were (Y)2,991 and (Y)2,930,
respectively. These figures were calculated based on the Black-Scholes Option
Pricing Model by using the following weighted average estimates.

                                       FY 2004 Interim         FY 2005 Interim
                                 -----------------------------------------------
Expected dividend yield                  0.6%                       0.5%
Risk free interest rate                  0.6%                       0.7%
Volatility                              56.6%                       51.1%

(Note 4) Investment Securities

         Investment securities consist of equity securities. As of September 30,
2004, September 30, 2005 and March 31, 2005, with respect to marketable
securities, aggregate fair value is (Y)4,287 million, (Y)4,344 million and
(Y)6,328 million, cost of (Y)3,177 million, (Y)1,784 million and (Y)3,803
million, gross unrealized gains, which are based on the specific-identification
method, is (Y)1,440 million, (Y)2,560 million and (Y)2,516 million, gross
unrealized losses as of September 30, 2004 is (Y)319 million yen.

         For FY 2004 interim, FY 2005 interim and FY 2004, gross realized gains
were (Y)629 million, (Y)934 million and (Y)934 million. Gross realized gains and
losses are principally included in "Other Income (expense)" in the interim
consolidated statements of income and consolidated statements of income, as well
as "other" of cash flows from operating activities in the interim consolidated
statements of cash flows and the consolidated statements of cash flows.

         Advantest maintains long-term investment securities, included in
marketable securities and other investments, issued by nonpublic companies,
which are recorded at cost and periodically assess for impairment.

(Notes)

1.   Adjustments to operating income (loss) included in Corporate mainly consist
     of research and development expenses for basic research activities, which
     are not allocated to corporate general administrative expenses and segment
     by business sector.

2.   Stock option compensation expense of (Y)759 million and (Y)755 million in
     FY2004 interim and FY2005 interim, respectively are not included in
     operating income in the business segment information. Operating income in
     the business segment information for FY 2004 does not include the temporary
     profit of (Y)3,317 million which arose from a return of the substitutional
     portion of its Employee's Pension Fund Plans and the stock option
     compensation expense of (Y)2,290 million. Therefore these operating income
     do not match with the operating income in the consolidated statements of
     income and the interim consolidated statements of income. Such exclusion
     was made since such items are not included in the performance review of
     each business segment by management.
