(1) Cross-default. The formation of credit risk is a gradual process from germination, accumulation to occurrence. Before the repayment period expires, the borrower's financial and commercial conditions have undergone major adverse changes, which may affect its performance ability. Lenders can not only guarantee the timely repayment of creditor's rights by agreeing on general default clauses and setting guarantees, but also stipulate cross-default clauses in the contract. The basic meaning of cross-default is that if the debtor under this contract defaults under other loan contracts, it is also regarded as a breach of this contract. 1.(2) The borrower is insolvent. If the borrower is declared bankrupt or insolvent through judicial procedures, or obviously unable to pay off due debts, or gives property to creditors or puts forward suggestions for giving property, it shall be regarded as an event of default.
