Like for like
From ACT Wiki
(LFL).
'Like for like' is a basis of comparison - usually of revenues - which seeks to exclude the effects of growth by acquisition or of any disposals.
The like for like comparison only takes account of activities which were in existence during both of the periods being compared.
Like for like comparisons should be treated with care, as the selection and presentation of relevant activities for comparison may involve a degree of subjectivity on the part of the management whose performance is being reported on.
Management may - consciously or unconsciously - be influenced to present figures in ways that reflect well on its own performance.
