The Daily Digit today is $42.35 billion. That's how much Microsoft is giving back to investors. It breaks down to a $40-billion buyback and $2.35-billion, or a 28-cent-per-share quarterly dividend. Analysts say the kickback reflects the growing influence of activist shareholder ValueAct, which has been pushing for a return of capital to investors. Also, with more than $77 billion in cash on Microsoft's balance sheet, it is a logical step to try and up the share price.
