在annual report中like for like sales是什么东东?

like-for-like sales: 本期销售额中,由与前期相同的销售活动实现的销售量的部分.是在排除本期销售活动变动带来的影响后的同比销售量.
“Using like-for-like sales is a method of valuation that attempts to exclude any effects of expansion, acquisition, or other events that artificially enlarge the company's sales. For example, if you are trying to compare the turnover of company ABC from this year to last year, it makes sense to exclude from the equation any sales resulting from acquisitions this year.”
