Answer: Reduction of cost basis per share
Step-by-step explanation:
It should be noted that Under IRS rules, when stock dividends are being received, they are not taxable at that particular time as shareholders haven't gotten any return from the stock yet.
The Stock dividend will then lead to reduction in cost basis per share. Therefore, based on the scenario in the question, the tax consequence of the distribution to the investor will be reduction of cost basis per share.
