Industrial Nanotech Inc (INTK)

INTK Industrial Nanotech lawsuit(s) in 2015?
In the last reported year (2015) there was an "unusual expense" of $674,167, which is enormous considering that total sales were $944,919, with a total loss for the year of $1,920,000.
Since Industrial Nanotech issues press releases for even the slightest good news including "discussions" and a change of accounting firms, I would guess (and it is only a guess) that this was bad news. I ask, was this either for payment or settlement for one or more lawsuits?
Of course, this could be for some other reason and Dr. Vedat Bilgin or Kolorgen or one of the officers from INTK Industrial Nanotech should be able to provide more complete information on what this $674,167 "unusual expense" was for.
