I occasionally deal with clients who are being hounded by collection agencies, not representing the credit-card lenders they couldn't pay but the vultures who buy up the debt for 5 cents on the dollar.  I think a lot of medical debt is bought that way, also.  So that might be what we're dealing with here.  On the other hand, it might be the All-American Widget Receiver Enterprise LLC, buying receivables from the All-American Widget Manufacturing Company Inc. for 90 cents on the dollar. 

In any case, I would consider the accounts as inventory, not capital assets.  There's a place on the second page of Schedule C for that.
