I got rid of Kyndryl about a week after the split.
I'm not sure if I've figured the Cost Basis for the Kyndryl shares split off from IBM pre-2011 (non-covered).
I created a spreadsheet for IBM share purchase date, Kyndryl shares purchased, Cost basis from adjusted IBM share value for the date. For each IBM share listed I calculated:
total cost basis = Kyndryl shares * adjusted IBM share value
cost basis as split = total cost basis * .2
Was this the correct way to do it?
