the value of the expected income return = d1/p0 - (Change in shares outstanding).
if they say repurchase yield = (anything positive here), this is a negative value as shares outstanding declines.
you would have a div yield of 4% - (-2% change) or a 6% value. only if shares outstanding grow will your income value decline.
Don’t forget that the expected earnings growth is a nominal value as well and you need to add the inflation figure to it.
this calculation will take out several people, maybe even myself.
