A company that both manufactures and distributes: blending both activities’ profits and benchmarking against pure distributors — is that fair? No. Segmented P&L is the technique for like-with-like comparison.
This article guides when to segment, how, and the risks of not segmenting.
When to segment — and how
Segment when the company runs materially different functions, assets and risks: manufacturing plus distribution; wholesale plus retail; or core business plus intragroup services. Each segment has its own “normal” margin — blending then benchmarking against a single-industry set gives wrong answers.
How: build a P&L per segment — segment revenue minus direct costs, then allocate shared costs (management, IT, shared plant rent) on reasonable keys. No single formula: keys must reflect each segment’s actual resource consumption (revenue, headcount, floor space, machine hours…).
Two mandatory requirements: (1) allocation keys must be reasonable and documented — “split evenly” is not always reasonable; (2) applied consistently across years — changing keys yearly for a desired margin is result-steering, spotted immediately.
Risks of not segmenting — and allocation methods
When accounting systems cannot segment (shared costs too large, no reliable allocation basis), the company must benchmark at entity level against multi-industry sets — far less reliable, with wider interquartile ranges, so the company’s margin more easily falls outside and gets adjusted.
The biggest risk: the authority segments its own way — and the authority’s way rarely favours the business. Having your own segmentation, however imperfect, beats letting the authority do it.
On shared-cost allocation, commonly accepted keys: revenue (sales, marketing costs), headcount (shared HR, IT), floor space (rent, plant depreciation), actual usage (shared production costs). The best key has the clearest causal link to the cost allocated — and that link must be demonstrated.
Frequently asked questions
How to split profit for a company that both manufactures and distributes?
When the company runs materially different functions/assets/risks: manufacturing plus distribution, wholesale plus retail, or business plus intragroup services. Each segment has its own “normal” margin — blending then benchmarking against one industry is wrong. Segment for like-with-like: manufacturing versus manufacturers, distribution versus distributors.
What are the risks if it cannot be split?
Build a P&L per segment: direct revenue minus direct costs, then allocate shared costs on reasonable, documented keys (revenue, headcount, floor space, actual usage…). Keys must reflect actual resource consumption and stay consistent across years — changing keys yearly for a desired margin signals steering.
Which method allocates shared costs?
Entity-level benchmarking against multi-industry sets — less reliable, wider interquartile ranges, margins easily falling outside and adjusted. Biggest risk: the authority segments its own way, rarely favourably. Your own segmentation, however imperfect, is better.
Segmented P&L is minimum courtesy in TP analysis for multi-activity companies: like-with-like comparison, grounded allocation, year-on-year consistency. If segmentation is impossible, accept weaker benchmarking — and prepare for adjustments.
