UN Secretary-General Antonio Guterres welcomed the General Assembly's decision on unspent budget funds. 

"I welcome today's (Tuesday's) decision by the General Assembly to reform financial rules that were putting the Organization's stability at risk. By its vote, the Assembly has agreed to introduce, for a four-year trial period, a new methodology to ensure that unspent funds are returned to Member States only when they are backed by cash," said Guterres in a statement.
