If the loan expires, the enterprise will apply for a loan from the bank after normal repayment, which is also called a new loan.
When the loan expires, the enterprise can't repay it normally. If the bank first proposes to borrow the second loan to repay the first loan, it is called borrowing the new and repaying the old.
If the enterprise borrows 6,543,800 yuan, it cannot be repaid at maturity. After bargaining with the bank, both parties decided that the enterprise would repay 200,000 yuan, and the bank would make a second loan for the remaining 800,000 yuan (800,000 yuan). This is called reducing loans and returning old ones.
If an enterprise fails to repay it at maturity, it is called overdue. If it is overdue for more than a certain period of time, banks will generally sue and enter legal procedures.
