	🧩 '''Business mix''' is how a company divides its business into parts, and the shares those parts take of the whole.

The second sense is the resulting composition, as in a group whose business mix has shifted toward protection and away from savings. Every listed company has a business mix. Insurers discuss theirs constantly, because their earnings behave differently depending on which risks and which contract durations dominate.		🧩 '''Business mix''' is how a company divides its business into parts, and the shares those parts take of the whole.

Business unit, business segment, business line, line of business, and product line all name slices, and issuers attach them to different axes with no shared convention. One insurer calls its geographic and legal-entity groupings business units, and reserves segment for the risk-type split between property & casualty and life & health. Another prints the reverse: geographies as segments, property & casualty as a line of business. A third applies line of business at the product level, so motor, home, and term life sit under a heading that its peer uses for whole divisions. Accounting adds a further sense. IFRS 8 defines an operating segment by what the chief operating decision maker actually reviews, which ties the segments a company reports to its internal management structure rather than to any external taxonomy. Reorganizations then move the labels around within a single issuer, so a label describes one company at one moment.

	📐 Two insurers can report identical revenue growth and mean entirely different things by it. Growth in commercial property carries catastrophe exposure that growth in health cover does not. Growth in savings contracts binds capital that protection business leaves free. Business mix explains gaps in margin and volatility between peers at least as often as underwriting skill does, which is why analysts rebuild the mix before comparing anything. The practical rule is to read the content under a label instead of trusting the label. A printed heading reflects ~~that~~ issuer's ~~own~~ convention, so the useful question is which entities, which risk types, and which products the figures underneath actually cover.		📐 Two insurers can report identical revenue growth and mean entirely different things by it.
