               Notes to 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. Unconsolidated
financial statements of Advantest Corporation and its subsidiaries are prepared
in accordance with accounting principles generally accepted in their respective
country of domicile. Certain adjustments and reclassifications have been
incorporated into such financial statements to reconcile to accounting
principles generally accepted in the U.S. ("U.S. GAAP").

(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 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 the accounts
of Advantest Corporation and its majority-owned subsidiaries. Advantest is not

No. 46 (revised December 2003) "Consolidation of Variable Interest Entities".
All significant intercompany balances and transactions have been eliminated in
consolidation.

     The following table sets forth the number of consolidated  subsidiaries and

               Notes to Interim Consolidated Financial Statements


(d)  Significant differences from the preparation of financial statements under
     Japanese GAAP

     Of the accounting principles, procedures and mode of presentation adopted
by Advantest Corporation and its consolidated subsidiaries (collectively
"Advantest"), the followings are the significant differences from the
preparation of financial statements using the accounting principles, procedure
and mode of presentation under Japanese GAAP:

     (i)   Scope of consolidation and application of the equity method
           The scope of consolidation and application of the equity method is
           determined based on percentage of voting rights. There is, however,
           no difference in results when compared to the situation where the
           scope is determined using the control criteria or influence criteria.

     (ii)  Appropriation of earnings
           Earnings appropriated for bonuses to directors are treated as
           selling, general and administrative expenses.

     (iii) Accounting for lease transactions
           Regarding significant lease transactions, property, plant and
           equipment and capital lease obligations are recognized if the lease
           is considered a capital lease under SFAS No. 13, "Accounting for
           Leases".

     (iv)  Allowance for compensated absences
           In accordance with SFAS No. 43, "Accounting for Compensated
           Absences", an allowance is provided for the right of employees to
           receive compensated absences in the future.

     (v)   Accrued pension and severance cost
           Accrued pension and severance cost is accounted for based on SFAS No.
           87, "Employers' Accounting for Pensions" and minimum pension
           liability adjustments are appropriated based on accumulated benefit
           obligation.

     (vi)  Goodwill
           In accordance with SFAS No. 142, "Goodwill and Other Intangible
           Assets", goodwill is no longer amortized, but instead is tested for
           impairment.

     (vii) Stock-based compensation
           In accordance with the fair value recognition provisions of SFAS No.
           123 (revised 2004) ("SFAS No. 123R"), "Share Based Payment",
           stock-based compensation expense evaluated at fair value is
           recognized.

(Note 2) 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.

          Description of the business by segment is as follows:

               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.

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

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

     (b)  Cash Equivalents

               Cash equivalents primarily 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.

                                     - 10 -



                              ADVANTEST CORPORATION
                                AND SUBSIDIARIES

               Notes to Interim Consolidated Financial Statements


     (c)  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.

     (d)  Inventories

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

     (e)  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 by the equity method. All
          significant intercompany profits from affiliates have been eliminated.

     (f)  Investment Securities

               Investment securities at September 30, 2005, September 30, 2006
          and March 31, 2006 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, 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.

               Notes to Interim Consolidated Financial Statements


               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 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.

     (g)  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.

               Notes to Interim Consolidated Financial Statements


     (h)  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.

     (i)  Intangible Assets and Other Assets

               Intangible assets principally consist of licenses, goodwill and
          computer software for internal-use. 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 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 generally
          capitalized subsequent to the attainment of technological feasibility
          until shipment of software in accordance with the provisions of SFAS
          No. 86, "Accounting for the Costs of Computer Software to Be Sold,
          Leased, or Otherwise Marketed". Costs incurred subsequently are
          expensed as incurred. 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 from 3 years to 5 years.

               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.

               Notes to Interim Consolidated Financial Statements



     (j)  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.

     (k)  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.

     (l)  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. 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.

     (m)  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.

               Notes to Interim Consolidated Financial Statements


          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.

     (n)  Research and Development

               Research and development costs are expensed as incurred.

     (o)  Stock-Based Compensation

               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 recognizes such cost as an expense in
          the statements of income. The fair value for stock options is
          calculated based on the Black-Scholes Option Pricing Model.

               Stock-based compensation expenses recognized were (Y)755 million
          in FY 2005 Interim, (Y)648 million in FY 2006 Interim, and (Y)1,884
          million in FY 2005.

               The weighted average fair value per share for stock options that
          were granted in FY 2005 Interim, FY 2006 Interim and FY 2005 were
          (Y)1,465, (Y)1,232 and (Y)1,219, respectively. These figures were
          calculated based on the Black-Scholes Option Pricing Model by using
          the following weighted average estimates.

               Notes to Interim Consolidated Financial Statements


               On October 1, 2006, a one to two stock split was made to shares
          of the common stock in respect of shareholders recorded in the
          register as of September 30, 2006. The weighted average fair value per
          share before stock split that were granted in FY 2005 Interim, FY 2006
          Interim and FY 2005 were (Y)2,930, (Y)2,464 and (Y)2,437,
          respectively.

                                   FY2005 interim   FY2006 interim     FY2005
                                   --------------   --------------   ---------
          Expected dividend yield       0.5%             0.5%            0.5%
          Risk free interest rate       0.7%             1.0%            0.4%
          Volatility                   51.1%            34.2%           51.0%
          Expected life              4 years        2.4 years       2.4 years

               Prior to FY2005 interim, the Company had used certain assumptions
          to determine the expected term of the Company's stock option plan.
          However, because of the changes in grantees' exercise behaviors for
          the year ended March 31, 2006, the previous assumptions no longer
          provide a reasonable expected term. Accordingly, the Company
          determined the expected term for stock options granted after April 1,
          2005 by using the "simplified" method accepted by the SEC Staff
          Accounting Bulletin(SAB) No.107. Under this method, the expected term
          is assumed to be the mid-point between the vesting date and the end of
          the contractual term. The use of the simplified method is only
          permitted for stock options granted through December 31, 2007.

     (p)  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.

     (q)  Net Income per Share

               Basic net income per share is calculated by dividing net income
          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.

               At September 30, 2005, September 30, 2006 and March 31, 2006,
          Advantest had outstanding stock options exercisable into 14,000,
          1,581,980 and 3,980 shares of common stock, respectively, which were
          anti-dilutive and excluded from the calculation of diluted net income
          per share but could potentially dilute net income per share in future
          periods.

     (r)  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).

     (s)  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 income.

     (t)  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.

               Notes to Interim Consolidated Financial Statements





          Advantest maintains non-marketable investment securities, which are
     recorded at cost. The carrying amounts of non-marketable investment
     securities were (Y)3,343 million, (Y)3,228 million and (Y)3,298 million at
     September 30, 2005, September 30, 2006 and March 31, 2006, respectively.
     For the six months periods ended September 30, 2006, Advantest recognized
     impairment losses of (Y)70 million on non-marketable investment securities,
     which were considered other-than-temporarily impaired and wrote them down
     to the fair value. The remaining investment securities with an aggregate
     cost of (Y)3,128 million did not have indicators of impairment.

(Note 7) Derivative Financial Instruments

          Derivative financial instruments are utilized by Advantest primarily
     to reduce foreign currency exchange risk. Advantest does not hold or issue
     financial instruments for trading purposes. Advantest generally does not
     require or place collateral for these 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 September 30, 2005,
     September 30, 2006 and March 31, 2006. The notional amounts of these
     contracts were (Y)13,621 million, (Y)6,753 million and (Y)10,929 million at
     September 30, 2005, September 30, 2006 and March 31, 2006.

          The carrying amounts and estimated fair values of Advantest's foreign
     exchange forward contracts at September 30, 2005, September 30, 2006 and

          These contracts do not qualify for hedge accounting since they do not

(Note 14) Per Share Data

          As resolved at the Board of Directors' Meeting held on July 26, 2006,
     a one to two stock split was made on October 1, 2006, to shares of the
     common stock in respect of shareholders listed in the register as of
     September 30, 2006.

          Basic and diluted net income per share was calculated based on the
     number of issued and outstanding shares after such stock split for all
     fiscal periods presented.

          The following table sets forth the computation of basic and diluted
     net income per share for the six months periods ended September 30, 2005
     and September 30, 2006, and for the year ended March 31, 2006:

 (Note 15) Commitments and Contingent Liabilities

          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 (Y)140 million at September 30, 2006. The guarantees are
     collateralized by the leased equipment. At September 30, 2006, 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.
