Step-by-step explanation:
In order to restore any reduction in loan basis, only the net increase is applied in line with section 1367(b)(Adjustment to basis of stocks of shareholders).
What this means is that there is no net increase regarding the information given above I.e ($11,000 - $15,000).
We can safely conclude that there is $11,000 tax free income since the stock basis has been increased by $11,000. There is also a $4,000 capital gain.
