       Numerator:
          Net income                                             17,329  million                 38,078  million
                                                             ------------                    ------------

          Dilutive effect of exercise of stock                  195,306  shares                 260,394  shares
          option and warrants
                                                             ------------                    ------------
          Diluted weighted average shares                    98,446,136  shares              98,010,739  shares
                                                             ------------                    ------------



At March 31, 2004 and 2005, stock options and warrants representing, upon
exercise, 329,500 shares and 7,000 shares, respectively, were outstanding but
were not included in the computation for net income per share (diluted) because
the foregoing did not have any dilutive effect.

 (Additional Information)
          On October 1, 2004, Advantest 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.
          Temporary profit on the return of the substitutional portion is
recognized in selling, general and administrative expenses. As a result, the
effect of such return on the operating income and net income for the current
consolidated fiscal year is (Y)3,317 million and (Y)1,981 million respectively.

          On December 16, 2004, the Financial Accounting Standards Board
("FASB") issued FASB Statement No. 123 (revised 2004), Share-Based Payment,
which is a revision of FASB Statement No. 123, Accounting for Accounting for
Stock Based Compensation. Statement 123R required employee stock options and
rights to purchase shares under stock option plans to be accounted for under the
fair value method, and eliminates the ability to account for these instruments
under the intrinsic value method prescribed by APB Option No. 25, Accounting for
Stock Issued to Employees, and allowed under the original provisions of
Statement 123. Statement 123R requires the use of an option pricing model for
estimating fair value, which is amortized to expense over the service period.
The requirements of Statement 123R are effective for the fiscal year beginning
after June 15, 2005. However, the Company early adopted Statement 123R in the
fourth quarter of this fiscal year by using a "modified retrospective" method
under which the Company restated prior interim periods of the year of adoption.
As a result of the adoption of Statement 123R, Operating income and Net income
have been reduced by (Y)2,290 million.
