Allowance for credit losses on debt securities available-for-sale

A credit loss exists if there is a decline in fair value of the security below the amortized cost as a result of the non-collectability of the amounts due in accordance with the contractual terms.

An allowance for expected credit losses is recorded in the consolidated statement of operations in provision for credit losses and the noncredit-related losses are recorded in accumulated other comprehensive income (AOCI). Subsequent improvements in the estimated credit losses are immediately recorded in the consolidated statement of operations as a reduction in allowance and credit loss expense. A security is written-off if it is considered certain that there is no possibility of recovering the outstanding principal. As of the end of 2Q20, the Group had no allowance for credit losses on debt securities available-for-sale.
