  None-the-less, it is apparent from the standings that his position is 
  improved because his net wealth has increased from -fc440 to -fc70:

  And then ten clicks later he can bid to by that note, too:

  fairwinds=> insert into note_bid (serial_number) values ('fc074d501302eb');
  INSERT 0 1

  In a non-competitive market, Bob may have the opportunity to extinquish that
  debt by first issuing a bond in order to raise money, and then make a bid to
  buy the outstanding note. (The reason Bob needs to issue a bond is because
  having a negative net cash balance means that he will not be permitted to
  place any buy orders.)
  
  Bob raises cash by bootstrapping the bond market and borrowing:
  
  --------------------------------------------
  fairwinds=> insert into bond_ask default values;
  fairwinds=> insert into bond_ask default values;
  --------------------------------------------
  
  
  This leaves him in the same place in the standings overall, 
  but the details of his wealth are altered buy borrowing Faircoin:

  That is, his net wealth remains unchanged at negative fc444, but he temporarily
  has cash on hand and so can place an order to buy the demand note upon which he
  is listed as the debtor:
  
  
  --------------------------------------------
  fairwinds=> insert into note_bid (serial_number) values ('91032ad7bbcb6c');
  INSERT 0 1
  --------------------------------------------
  
  
  which results in Bob becoming listed as factor as well as the debtor on bond
  `91032ad7bbcb6c`:

                            Notes

  Bob then waits for time to advance beyond the bond maturity. When the bond is
  redeemed, his fc70 cash short-fall results in a new bond, bond
  `fc074d501302eb`, scheduled for issuance ten clicks from the present at click
