Allocating Insurance Premium Across Business Units and Cost Centres

Why finance needs premium allocated

Insurance bought centrally is cheaper and simpler, but a single premium charged to head office overhead hides the cost from the people who create it. Finance needs it broken down for several reasons:

• P&L by unit. A plant that carries ₹150 crore of insured assets should show the cost of insuring them, or its margin is flattered and another unit’s is penalised.
• Transfer pricing. Where units are separate legal entities, the cost of group cover recharged to them must rest on a defensible basis. An arbitrary split is a tax exposure as well as an accounting one.
• Captives and self-retention. If the group retains part of its risk through a captive or a large deductible fund, units must be charged for the retained layer as well as the transferred one, or nobody will see the true cost of risk.
• Behaviour. A unit that sees its own premium, and sees it rise after a poor claims year, has a reason to maintain fire systems and chase reimbursement papers. A unit that never sees it does not.

Choosing an allocation basis

The basis should follow what drives the premium in that class. Insurers rate property on values, health on lives, marine on shipments; mirror that, so a unit’s share moves with its own exposure.

• Sum insured share for fire, property, machinery breakdown and electronic equipment. A plant with a third of the group sum insured bears a third of the premium.
• Headcount or lives covered for group health, GPA and GTL. Use the actual member count on the policy, including dependants where the premium is per family, and weight by sum insured band if units have different grades.
• Revenue or turnover for liability lines rated on turnover, and for classes where no cleaner driver exists.
• Declared value of sendings for marine open cover, using each unit’s declarations.
• Claims experience as an adjustment layered on any of the above. A unit whose claims ratio ran well above the group’s can carry a loading; one with a clean record a discount. Keep the adjustment modest and transparent, or it becomes a quarrel.

A worked example. A group fire policy costs ₹36 lakh and covers three plants with sums insured of ₹150 crore, ₹100 crore and ₹50 crore. On a sum insured basis the shares are 50%, 33.3% and 16.7%: ₹18 lakh, ₹12 lakh and ₹6 lakh. A group health policy costs ₹1.2 crore for 1,200 lives, or ₹10,000 per life; a unit with 400 lives is charged ₹40 lakh. Both are simple, explainable to a unit head, and move with the unit’s exposure.

Group policies versus unit policies

Some groups sidestep allocation by letting each unit buy its own policies. It removes the arithmetic but usually costs more: smaller sums insured attract higher rates, the group loses bargaining weight, terms diverge between units, and head office loses sight of the whole. The multi-location programme guide sets out the case for consolidating.

The middle route is a group policy with a schedule that lists each unit’s locations, assets and lives separately. The insurer often prices it that way in any case, and the schedule then gives you the allocation basis for free: each unit’s share of sum insured, or of lives, is already on the document. Where the insurer applies different rates to different locations, because of construction or fire protection, use the location-level premium rather than a flat share, so the plant with the sprinklers benefits from having them.

Budgeting for the year

The insurance budget is built before renewal and tested against it. A practical sequence:

• Start from the current year’s premium per policy, adjusted for all endorsements to date, so the base reflects the exposure actually on cover
• Apply each unit’s expected exposure change: capital additions, disposals, headcount plans, revenue forecasts
• Apply an assumed rate movement per class, based on the broker’s market view and your own claims record
• Allocate the resulting premium to units on the agreed basis
• Hold a small central contingency for mid-term additions that units have not yet planned

After renewal, replace the assumptions with the actual premiums and re-run the allocation. The variance then splits cleanly into three parts: exposure variance (the unit insured more or less than planned), rate variance (the market moved), and allocation variance (the mix shifted between units). Reporting all three stops the conversation collapsing into “insurance went over budget” when the real story is that one plant commissioned a line early.

Tie the budget to the renewal calendar: policies renewing in different months mean the budget year straddles two policy years, and the accrual must reflect that. Aligning renewal dates, covered in insurance renewal management, simplifies this.

Reporting per unit

Each unit head should receive, at least quarterly, a one-page view of their own insurance position:

• Policies under which the unit is covered, with the unit’s sum insured and lives on each
• Premium allocated to the unit for the year, budget versus actual, with the variance split as above
• Endorsements raised for the unit in the period and their premium effect
• Claims intimated, settled and outstanding for the unit, with the unit’s claims ratio
• Actions outstanding: valuation updates, documents pending on claims, sites not yet endorsed

The same data rolled up gives finance the group view and gives the board the programme totals. All three should come from one dataset, so the units sum to the group invoice and nobody reconciles spreadsheets before a meeting. SAIBA Corporate holds policies, assets, lives and claims against business units and cost centres and produces the unit and group views from the same records.

Charge the allocated premium through an internal recharge that references the policy and the basis, so the answer to how the number was reached is on the face of the entry.

Pitfalls to avoid

The same mistakes recur.

• Double counting. Stock in transit between two plants is insured under marine, not under each plant’s fire policy; assets on the head office schedule that also appear on a plant register get charged twice. Reconcile the allocation base to the policy schedule, not to whatever each unit reports.
• Mid-term endorsements ignored. A unit that adds ₹20 crore of plant in month four has changed its share of the group sum insured. Re-run the allocation at each endorsement or at least quarterly, and charge the additional premium to the unit that caused it. See the endorsements guide for keeping the log that makes this possible.
• Currency. Gulf and African units may be insured under local policies in local currency, or under a group policy priced in another. Allocate in the policy currency and convert at a stated rate on a stated date; do not let each unit convert at its own rate.
• Taxes and levies. Decide whether allocations are gross or net of GST, VAT and local levies, state it, and keep it consistent.
• Changing the basis mid-year. A switch from headcount to revenue in month eight is a reallocation, not a cost change, and unit heads will read it as one. Change bases only at year start, with notice.
• Allocating premium but not claims. If units bear the cost, they should see the recoveries. A unit that pays its share of premium and then watches a claim credit land in central overhead learns the wrong lesson.
