【求助】net additions指的是什么?

An investment banking firm has lowered its handset forecast amid the economic storm. As part of our handset industry revisions, we are lowering our (calendar 2009) global handset sell-in forecast to 1.267 billion (minus 1 percent year-over-year) from 1.357 billion (plus 4 percent year-over-year) on weaker (calendar 2009) net additions (minus 17 percent year-over-year) and further macro deterioration as developed market recessions bleed into emerging markets,'' said Matthew Hoffman, an analyst with Cowen and Co. LLC, in a new report.

year-over-year：在金融行业常缩写为y-o-y，是指跟上一年比较。year on year也是这个意思。

net additions：净增长

emerging markets：新兴市场，如韩国、中国等。

to 1.267 billion (minus 1 percent year-over-year) from 1.357 billion (plus 4 percent year-over-year) on weaker (calendar 2009) net additions (minus 17 percent year-over-year)

是这个意思,但2009年的12.67亿与2008年的13.57亿相比,下降1%,2008年的13.57亿与2007年比,增长4%,净增长百分比-17%就是(2009年的数据-2008年的数据)/(2008年的数据-2007的数据),可计算一下,不符合!

文中讲的是分析师下调对09年手机销售的预期。原来对09年手机出货销售（把货卖给分销商或零售商）的销售额的预期是13.57亿，现在受全球经济衰退影响，将预期下调至12.67亿。-1％和4％讲的是销售额。这里的net addition讲的应该是手机销售数量的净增长，而不是销售额。

net addition是手机销售数量就通了,谢谢!

net additions：净增长
应该是年度之间增加差额的17%吧
