We wish to advise that we have revised the expected business results for the fiscal year ending March 2007 (From 1 April 2006 to 31 March 2007) that were published in the announcement of the midterm account settlement on 2 November 2006.

We wish to revise the expected business results‚ because it is unlikely that we will meet the expected business results published in the announcement of the midterm account settlement, on both a consolidated and an unconsolidated basis. (Note) The above expected business results are based on all information available at this time‚ but for various reasons the actual results may differ from the expected results.
