I looked the the dividend history for CBA.AX
and I went to the CBA website and found a completely different set of numbers!
https://www.commbank.com.au/about-us/shareholders/managing-your-shares/dividend.html
For example, the dividend for the half year ending 31 Dec 2017 is shown by CBA as $2 but Yahoo shows $2.8571.
Yahoo's numbers are different. Why is that?
