(Note)        1.  Advantest Corporation restructured two reporting segments of
                  'Automated Test Equipment' and 'Measuring Instruments' into
                  three segments of 'Semi-Conductor and Component Test System'
                  'Mechatronics System' and 'Services, Support and others.'
                  Therefore, necessary adjustments and reclassification to the
                  segment information for the preceding consolidated interim
                  period and preceding consolidated fiscal year have been made
                  to conform with the presentation of the current consolidated
                  interim period.
               2. Adjustments 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.
               3. The operating profit in the business segment information for
                  this fiscal year and in the consolidated income statement do
                  not match with the operating income in the consolidated income
                  statement as the business segment information does not include
                  the temporary profit of (Y)3,317 and the stock option cost of
                  (Y)2,290. Profit and loss from these are not included in
                  management's analysis of results.
               4. Total assets included in Corporate consist of cash and cash
                  equivalents, assets for general corporate use and assets for
                  general corporate use and assets used for fundamental research
                  activities, which are not allocated to reportable segments.
