Just did some very rough calcs to see how many shares averaged over the last 4 weeks and came up with roughly 12mil. The present outstanding shares are about 320mil, so 10% would be 32 mil and 20% 64 mil. Thus if the company bought back the max which was determined to be 100% of the average volume over the last 4 weeks each trading day, within 3 days they could buy back 10% and roughy 5 days to buy back 20%. It would appear that we can also use the average weekly shares for the last 4 weeks as a very rough indicator of how many shares are being bought back each day by the number of shares traded that exceed 12 mil. Open for comments.
Not that much considering * The company and affiliated purchasers can't bid at or settle at a purchase price that exceeds the highest current independent bid quote or the last independent sales price, whichever is higher.
