non standard option
If you sell a put on a non standard option and it expires
out of the money, do you just keep the premium and you are
done or are you on the hook for something more.


if the option expires out of the money, you are 'done.'
Your obligations are canceled and the premium becomes the profit.

But: Be certain you know that the option is out of the money. The option must
have no bid and be truly worthless.
