W534220 my calculations for the dividend came out at .95, slightly higher. I can’t figure out where I have gone wrong, these are my calculations

315,951,686 number of shares outstanding before buyback
315,951,686- (10,330,297+287,491) 10,617,788 shares bought back up until the 1/11/23 + shares bought back on the 2/11/23
= 305,333,898 as of 2/11/23
Total number of shares 10,617,788/45 (trading days so far) = 235,950 avg shares bought back per day
Total trading days all up 96
96X235950= 22,651,200 expected shares bought back
315,951,686- 22,651,200 = 293,300,486 shares outstanding after buy back
I went with your 280 million
280,000,000/ 293,300,486= .95 per share
.95- .14 (dividend already paid) =.81
If anyone can help me out, input would be great
