A brief study of the charts at http://tr.im/vDA4 ( CourtesyGoogle Finance) would suggest IBM is getting a bargain for SPSS Inc.
And Oracle, Microsoft and other companies ( even the privately held SAS Institute) can do well to step in and take it away or at the very minimum make the valuation even more steep for IBM to hold on to.
SPSS reported in 2007 Total Revenue of $291million with a Net Income of $33.73million and in 2008 Total Revenue of $302.91million with a Net Income of $36.05million. Shares of SPSS Inc. (Public, NASDAQ:SPSS) increased from about $35 per share before the announcement to $49.50 per share after the announcement.
