I invested in a friend's start-up via a convertible note. The business has ceased operations and I am curious how to write off this investment. I recovered a portion of the original principal investment from a few years ago. The convert did not pay any cash interest over its life outstanding. 

The below seems similar but I want to make sure there is no difference since I had a 28% recovery.

The instructions are fine, you just need to reduce your cost basis in the investment by the recovered amount.
