再进一步假定相对宽松的20%的行政人头支出，这一项目的总体成本大约是六亿美元，相当于2004年记录给予这些国家援助的五分之一及其GDP总和的3.5%到4 % 。
Further assuming a relatively generous 20% administration overhead, the total cost of the scheme would be approximately $600 million – equivalent to a fifth of the reported aid flow to these countries in 2004 and to 3.5-4% of their combined GDP.
