ADVANTEST CORPORATION

AND SUBSIDIARIES

Notes to Consolidated Financial Statements (Unaudited)

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

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

Advantest Corporation (the “Company”) and its consolidated subsidiaries (collectively, “Advantest”) prepare its consolidated financial statements in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”).  U.S. GAAP is codified in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), which is the source of authoritative accounting principles recognized by the FASB to be applied by nongovernmental entities.

Advantest prepared the accompanying interim consolidated financial statements in conformity with U.S. GAAP, consistent in all material respects with those applied in Advantest’s Annual Report on Form 20-F/A (Amendment No.1) for the year ended March 31, 2012.

The interim financial statements are unaudited, but reflect all normal adjustments that are, in the opinion of management, necessary to provide a fair presentation of results for the interim periods presented.  This interim information should be read with the consolidated financial statements in Advantest’s Annual Report on Form 20-F/A (Amendment No.1) for the year ended March 31, 2012.

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

The Company became listed on the New York Stock Exchange on September 17, 2001 (local time) by means of an issuance of American Depository Shares, and has been filing a Form 20-F (equivalent to the Annual Securities Report in Japan) with the U.S. Securities and Exchange Commission since the year ended March 31, 2002.  Advantest prepares the consolidated financial statements in its Form 20-F in accordance with U.S. GAAP.

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

Of the accounting principles, procedures and method of presentation adopted by Advantest, the following is a brief summary description of the significant differences from the preparation of financial statements using the accounting principles, procedures and methods of presentation under Japanese GAAP, as required under the Financial Instruments and Exchange Law of Japan:

(i) Allowance for compensated absences

An allowance is provided for the right of employees to receive compensated absences in the future.

(ii) Accrued pension and severance costs

The funded status, which is the difference between the fair value of plan assets and the projected benefit obligation, of pension plans is recognized in the consolidated balance sheets.

(iii) Business Combination

Goodwill arising from business combination is not amortized, but instead is tested for impairment at least annually. Acquisition related costs are expensed as incurred.

(iv) Stock option

Expired unused gains from stock based compensation are not recognized in the case of expiration of stock option.

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

(a) Description of Business

Advantest manufactures and sells semiconductor and component test system products 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.

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 in the semiconductor and component test system segment include test systems for memory semiconductors for memory semiconductor devices and test systems for SoC (“System-on-a-Chip”) 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) Accounting Changes and Accounting Standards Not Yet Adopted

In June 2011, the FASB amended the accounting guidance for the presentation of comprehensive income. This new guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity and provides the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In December 2011, the FASB deferred the effective date for presentation of reclassifications out of accumulated other comprehensive income. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The guidance was adopted by Advantest in the first quarter beginning April 1, 2012. The adoption of the guidance did not have a significant impact on its consolidated results of operations and financial condition.

ADVANTEST CORPORATION

AND SUBSIDIARIES

Notes to Consolidated Financial Statements (Unaudited)

In February 2013, the FASB finalized the accounting guidance for reporting of amounts reclassified out of accumulated other comprehensive income. This new guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2012, with early adoption permitted. The guidance is required to be adopted by Advantest in the first quarter beginning April 1, 2013. Advantest is currently evaluating the timing and the effect that this adoption will have on its consolidated results of operations and financial condition.

In September 2011, the FASB amended the accounting guidance for testing goodwill for impairment. This new guidance gives entities the option to perform the two-step process only if they first perform a qualitative assessment and conclude that it is more likely than not (a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount. The guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 with early adoption permitted. The guidance was adopted by Advantest in the first quarter beginning April 1, 2012.  The adoption of the guidance did not have a significant impact on its consolidated results of operations and financial condition.

In July 2012, the FASB amended the accounting guidance to simplify how entities test indefinite-lived intangible assets for impairment which improve consistency in impairment testing requirements among long-lived asset categories.  The guidance permits an assessment of qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value.  For assets in which this assessment concludes it is more likely than not that the fair value is more than its carrying value, the guidance eliminates the requirement to perform quantitative impairment testing as outlined in the previously issued standards.  The guidance is effective for fiscal years beginning on or after September 16, 2012, with early adoption permitted.  The guidance is required to be adopted by Advantest in the first quarter beginning April 1, 2013.  Advantest is currently evaluating the timing and the effect that this adoption will have on its consolidated results of operations and financial condition.

(c) Reclassification

Certain reclassifications have been made to the prior fiscal year’s consolidated financial statements to conform to the current quarter and year-to-date presentation.

(3) Business Combinations

On July 4, 2011, Advantest acquired all outstanding ordinary shares of Verigy Ltd. (“Verigy”), for US$15.00 per share in cash.  Verigy became a wholly-owned subsidiary of Advantest.  In addition, as part of the consideration in the acquisition, Advantest assumed the obligation for stock options which had been granted by Verigy to certain directors and employees.

Summary of the total purchase price is as follows.

	Yen (Millions)
Cash paid	77,661
Assumed stock options	1,068
Total purchase price	78,729

Acquisition-related costs for the nine months ended December 31, 2011 were ¥1,285 million and there were no acquisition-related costs for the three months ended December 31, 2011.  These costs were included in “Selling, general and administrative expenses” in the consolidated statements of operations.

Verigy has historically been strong in the non-memory tester and research and development markets in North America and Europe.  The complementary strengths in products, customer base, research and development, sales and service are expected to enhance combined company’s competitiveness in the global market.  The acquisition will allow Advantest to provide more and better diversified solutions to its customers in the semiconductor test equipment sector.

This acquisition was accounted for using the acquisition method.

The table below summarizes the allocation of the purchase price based on the fair value of assets acquired and liabilities assumed as follows.

	Yen (Millions)
Assets acquired and liabilities assumed
Cash and cash equivalents	20,516
Trade receivable, net	2,104
Inventories	11,013
Property, plant and equipment	3,316
Intangible assets	16,899
Goodwill	35,140
Other assets	20,145
Trade accounts payable	(3,136)
Other liabilities	(27,268)
Net assets acquired	78,729
Purchase Price	78,729

Goodwill recognized is attributable primarily to expected synergies from combining operations of Verigy and Advantest.  None of the goodwill is expected to be deductible for income tax purposes.

	Acquisition cost		Gross unrealized gains		Gross unrealized losses		Fair value
Noncurrent:

Proceeds from the sale of available-for-sale securities for the nine months and three months ended December 31, 2011 were ¥10,262 million and ¥500 million.  Gross realized gains on available-for-sales securities for the nine months ended December 31, 2011 were ¥19 million. Gross realized gains on available-for-sales securities for the three months ended December 31, 2011 were insignificant.  No gross losses were realized on the sale of available-for-sale securities.  No proceeds from the sale of available-for-sale securities and no gross gains and losses were realized on the sale of available-for-sale securities for the nine months and three months ended December 31, 2012.

Net realized gains and losses of the sale of available-for-sale securities are based on the averaged cost method and are included in “other income (expense)” in the consolidated statements of operations.

For the nine months and three months ended December 31, 2011, Advantest recognized impairment losses of ¥1,259 million and ¥109 million on available-for-sale securities, which were considered other-than-temporarily impaired.  For the nine months and three months ended December 31, 2012, Advantest recognized impairment losses of ¥388 million and nil on available-for-sale securities, which were considered other-than-temporarily impaired.

Gross unrealized losses on available-for-sale securities and the fair value of the related securities, aggregated by length of time that individual securities have been in a continuous unrealized loss position, at March 31, 2012 and December 31, 2012, were as follows:

Advantest maintains non-marketable equity securities, which are recorded at cost and included in “investment securities” in the consolidated balance sheets.  The carrying amounts of non-marketable equity securities were ¥450 million and ¥450 million at March 31, 2012 and December 31, 2012, respectively.  For certain non-marketable equity securities which Advantest identified events or changes in circumstances that might have had significant adverse effect on the fair value of the investments, the fair value approximates the carrying value.  Advantest had not estimated the fair value of the majority of these non-marketable equity securities aggregating ¥50 million and ¥450 million at March 31, 2012 and December 31, 2012, respectively, since it was not practicable to estimate the fair value of the investments due to the lack of readily determinable fair values and difficulty in estimating fair value without incurring excessive cost. Non-marketable equity securities that had impairment indicators were evaluated to determine whether the investments were impaired and the impairment, if any, was other than temporary.

(6) Derivative Financial Instruments

Advantest uses derivative instruments primarily to manage exposures to foreign currency. The primary objective in holding derivatives is to reduce the volatility of earnings and cash flows associated with changes in foreign currency. The instruments are not designated for trading or speculative purposes. 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 generally does not require or place collateral for these derivative financial instruments.

Notes to Consolidated Financial Statements (Unaudited)

In accordance with U.S. GAAP, Advantest recognizes derivative instruments as either assets or liabilities on the balance sheet at fair value. Changes in fair value of the derivatives are recorded as other income (expense).

Derivatives not designated as hedging instruments

Derivatives not designated as hedging instruments consist primarily of forward contracts to reduce Advantest’s risk associated with exchange rate fluctuations, 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 contracts are recognized in earnings under the caption of other income (expense).

Advantest had foreign exchange contracts to exchange currencies among Japanese yen, US dollar and Euro at March 31, 2012 and December 31, 2012. The notional amounts of outstanding forward contracts for foreign currency purchases were approximately ¥653 million, and the outstanding forward contracts for foreign currency sales were ¥280 million at March 31, 2012. The notional amounts of outstanding forward contracts for foreign currency sales were ¥575 million at December 31, 2012.

Disclosure about the fair value of Financial Instruments

The following table presents the carrying amounts and estimated fair values of Advantest’s financial instruments at March 31, 2012 and December 31, 2012.  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 judgment and, therefore, cannot be determined with precision.  Changes in assumptions could significantly affect the estimates.

The carrying amounts of available-for-sale securities are included in the consolidated balance sheets under investment securities.  The carrying amounts of foreign exchange contracts are included in other current assets and other current liabilities.

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

Cash and cash equivalents, trade receivables, trade accounts payable, short term debt and accrued expenses:  The carrying amounts approximate fair value because of the short maturity of these instruments.

Available-for-sale securities:  The fair values of available-for-sale equity securities are based on quoted market prices at the reporting date for those investments.

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

Corporate bonds:  The fair value of corporate bonds is estimated using market quotes and are classified as Level 2.

Fair Value Hierarchy

U.S. GAAP defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date.  Additionally the inputs to valuation techniques used to measure fair value are prioritized into the following three levels:

Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 - Observable inputs other than quoted prices included within Level 1 for the asset or liability, either directly or indirectly.

Level 3 - Unobservable inputs for the asset or liability.

Assets / Liabilities Measured at Fair Value on a Nonrecurring Basis

As of March 31, 2012 carrying amount of assets and liabilities, which were measured at fair value on a nonrecurring basis by level during the years ended March 31, 2012 was as follows:

			Yen (Millions)
			Fair Value Measurements at March 31, 2012

Total assets measured at fair value	¥	1,871		-		400		1,471

For the nine months ended December 31, 2011, Advantest recognized impairment loss of ¥920 million on certain building and land included as a corporate asset that was reclassified as assets held for sale and impairment loss of ¥195 million on non-marketable equity securities when their fair values were below the carrying amounts and the decline in fair values was considered to be other than temporary.  The impairment loss was included in selling, general and administrative expenses in the accompanying consolidated statements of operations.  The fair value of the assets held for sale was reclassified to other current assets on the consolidated balance sheets.  As of December 31, 2012, Advantest reclassified certain land of ¥1,144 million as asset held for sale.  The asset held for sale was included in other current assets on the consolidated balance sheets.  As of December 31, 2012, there were no amount of assets and liabilities, which were measured at fair value on a nonrecurring basis.

The non-marketable equity securities are valued using the market and income approaches.  The fair value of non-marketable equity securities is based on quoted prices in markets that are not active at the reporting date, or present value of expected future cash flows for those investments.  The fair value of assets held for sale was determined based on a third-party appraisal using similar assets and sales and is classified as Level 3 because significant unobservable inputs were involved in the fair value measurements.

(9) Income Taxes

As of December 31, 2011 and 2012, the estimated annual effective tax rate for FY2011 and FY2012 differ from the 40.4 and 37.8 percent statutory income tax rate primarily due to related impacts of valuation allowance on deferred tax assets, effects of foreign income tax rates, and effects of separate company income tax reporting positions.

In July 2012, stock options were issued to directors, corporate auditors, executive officers and employees of the Company and directors and employees of its domestic and foreign subsidiaries under a stock option plan approved by the Board of Directors.  The number of granted shares totaled 2,521,000. Options were granted with an exercise price of ¥1,207 per share that is equal to the higher of (1) 1.05 times the average price of the Company’s common shares of the preceding month on the date of grant and (2) the closing price of the Company’s common shares traded on the Tokyo Stock Exchange on the date of grant. The options have an exercise period of 4 years and are exercisable from April 1, 2013.

Stock based compensation expense recognized was ¥408 million and ¥581 million for the nine months ended December 31, 2011 and 2012, and ¥190 million and ¥290 million for the three months ended December 31, 2011 and 2012, which were included in selling, general and administrative expenses.
