Revenue Split by Activity
Revenue split by activity records the breakdown of an insured's total turnover across its different business activities or product lines, allowing underwriters to allocate premium and business interruption sum insured proportionately to each activity's distinct risk profile.

Typical proposal-form questions
- Please provide a breakdown of total turnover by main business activity or product line for the last completed financial year.
- Are any activities materially growing or shrinking as a share of total turnover compared with the prior renewal?
- Do any activities carry a distinct risk profile (e.g. higher-hazard manufacturing, design services, distribution) that should be separately identified?
Evidence
- Audited financial statements with segment reporting
- Internal management accounts by activity
- Revenue declaration form
Why it matters for underwriting
Most insured businesses do not consist of a single homogeneous activity; a single legal entity may combine manufacturing, design services, distribution and after-sales repair under one policy, each carrying a materially different liability and business interruption risk profile. Rating on total turnover alone without a breakdown by activity risks either overcharging low-hazard revenue streams or undercharging high-hazard ones, and can obscure a shift in the business mix, such as growth in a higher-risk design or installation activity, that would otherwise go unnoticed between renewals. Underwriters use the revenue split to apply differentiated rating and to correctly allocate business interruption sum insured across activities with different recovery profiles.
Capturing the attribute and evidence
Proposal forms ask for a breakdown of total turnover across the insured’s main business activities or product lines for the last completed financial year, together with commentary on any activities growing or shrinking materially as a share of the total. Underwriters verify the declared split against audited financial statements with segment reporting where available, internal management accounts, and the completed revenue declaration form, cross-checking that any high-hazard activity flagged elsewhere in the proposal is reflected with an appropriate revenue share.
Effect on coverage, premium and conditions
An accurate, activity-level revenue split allows premium to be rated proportionately to each activity’s actual hazard, generally producing fairer overall pricing than a blended rate applied to total turnover. Where a material share of revenue derives from an activity not clearly identified in the proposal, insurers commonly apply retrospective premium adjustment at audit, sublimits for the undisclosed activity, or conditions requiring more granular revenue reporting at each renewal.
Mitigation measures
Insureds are encouraged to maintain segment-level revenue reporting as part of standard management accounting, flag any material shift in business mix to their broker or insurer proactively rather than waiting for renewal, and ensure that new activities are explicitly declared and rated before they represent a significant share of turnover.
