Under-Secretary-General for Management Catherine Bertini told the General Assembly’s Administrative and Budgetary Committee on Tuesday that unpaid regular budget assessments from 78 countries totalled $693 million, while the arrears for peacekeeping was $1.56 billion.”The financial stability of the organization is under pressure,” she said. “We must be able to rely on payment in full and on time to provide the predictable resource base needed to carry out all our mandated activities.”The United States contributed $31 million of its regular dues earlier in the year and said it would send in another $233 million to $341 million, depending on congressional action, by the end of the year. If it got the lower amount, the United Nations would be $5 million in the red; if the higher amount, it would have a surplus of $103 million, Ms. Bertini said.At the end of September, the United States owed $732 million for peacekeeping, but it paid $252 million of that on Monday, she said. Fourteen other major contributors owed $464 million.Nonetheless, the organization was reimbursing Member States for troops and equipment as promptly as possible. It had paid $339 million in troop costs and planned to add another $64 million by year’s end, she said.Meanwhile, the war crime tribunals for Rwanda and the former Yugoslavia were $117 million in the hole, compared to an unpaid amount at this time last year of just $49 million, so they, too, had had to borrow from peacekeeping funds, Ms. Bertini said. Sixty States had paid their tribunal assessments in full, but five major contributors owed $102 million and 126 others owed $15 million.
