Disposal of assets (C-corp, Form 1120 Schedule K line 17)

"During or subsequent to this tax year, but before the filing of this return, did the corporation dispose of more than 65% (by value) of its assets in a taxable, non-taxable, or tax deferred transaction?"

 

I am wondering what constitutes the "disposal" as mentioned above by the IRS. If my C-corporation has performed a liquidation/nondividend distribution to return back all investor capital and profits would this qualify as a "disposal of assets"?

 

Or does "assets" only mean stock/shares? Currently my C-corp has $0 in remaining cash/assets.
