Debt on which the interest

متن زیر به چه اصطلاح مالی اشاره داره ؟

Debt on which the interest and redemption payments due are not in fact
being made. Non-performing debt is an embarrassment to lending
institutions: they suffer not merely direct financial loss, but also damage to
their reputation for sound judgement in picking borrowers. There is thus a
temptation to camouflage non-performing debt by making fresh loans to
finance repayment of earlier ones.
