TAKING A SENTENCE OUT OF PARAGRAPH CHANGES THE INTENDED MEANING ...But,your comment regarding the IRS brings to mind another point...
Is it your contention that this stock dividend is in and of itself a taxable event ? But let me say distribution instead of dividend...
I suggest that it is not a taxable event for you and I unless or until it is sold....and I believe the basis (cost) will be zero....Whatever is obtained by selling will be taxed 100% POTENTIALLY,subject to other overall influences of earnings , interest, etc on one's 1040...
