Well, my point comes back to the use of the term "all old equity". Repeatedly.
I'm not sure how that can be interpreted to exclude whole shares of "equity". As whole shares of equity would seem (to me at least) be included in the term "all equity".
if you were holding a fractional share from a prior split, when this last split happened and they rounded up all fractional shares then your old fractional would round up leaving no shareholder holding any fractional share(s)
