Understanding Product Lining

In practice, product lining begins from a company’s revenue breakdown by operating segment, which the classifier must reinterpret functionally since segments are often organized by geography or customer rather than by product; because a firm’s revenue rarely maps to a single functional position, this step actually determines how many separate barcodes a company requires and which of them becomes its Summary Barcode. Revenue is the default metric because it is the most objective figure companies report, though there are exceptions (insurers use net written premiums, banks use net interest income). When no clear breakdown exists, classifiers use standardized “industry-informed rounding assumptions” marked with a “~” prefix, drawn from a fixed set of conventions — 100/0, quarters, thirds, or an even 1/n split across n products — so that assumptions are consistent and visibly flagged as estimates rather than reported figures.
