Not sure the relevancy here. The OP is indicating that they have no basis.
What were you disagreeing with in the previous post?
In most of these contexts basis and at-risk will be used interchangeably. Especially in an S corp context.
Where this becomes more "technical" is in the partnership arena, but most will correlate at-risk and basis as one and the same. If you are at-risk you have basis to take losses.
