(2)Borrowers classified as Likely to become Bankrupt or Legally/Virtually Bankrupt represent those that have a higher probability of default than those categorized as Close Watch due to serious debt repayment problems with poor progress in achieving restructuring plans, the borrower being considered virtually bankrupt with no prospects for an improvement in business operations, or the borrower being legally bankrupt with no prospects for continued business operations because of non-payment, suspension of business, voluntary liquidation or filing for legal liquidation.
