Sony estimates that the above-mentioned sale of shares will contribute
approximately 18.0 billion yen to consolidated income before taxes and
approximately 10.6 billion yen to consolidated net income. As the impact of this
transaction is not incorporated within the outlook for the fiscal year ending
March 31, 2006, announced on July 28, 2005, Sony is currently reviewing whether
or not a revision of the outlook is required taking into account a number of
uncertainties, including an ongoing detailed review of company-wide business
strategy and operating structure being conducted by Sony's new senior executive
