Reinsurance Premium Instalment Tracking: No Missed Payments

Reinsurance Premium Instalment Tracking: Stopping Missed Deposit and Adjustment Payments

Last reviewed: November 2026

The third deposit instalment on a cat programme is six weeks late, and nobody has noticed. The adjustment premium from two years ago was never billed at all.

Short answer: Reinsurance premium instalment tracking builds a payment schedule from each treaty's deposit and adjustment terms, then matches every receipt against it. Late instalments are chased on a fixed timetable, and adjustment premiums are triggered automatically when the treaty expires.

Key Takeaways

• Build the schedule at binding. Instalment dates and amounts belong in the treaty record, not a spreadsheet.
• The adjustment is the weak point. It depends on a declaration that someone must request after expiry.
• Know the clause. Premium payment terms decide what remedies exist when money is late.
• Track at 100% and by share. Panel shares, brokers and currencies multiply the items to follow up.

What Is Reinsurance Premium Instalment Tracking?

Reinsurance premium instalment tracking is the monitoring of every scheduled premium payment under a treaty. It covers deposit instalments during the period and the adjustment premium after it.

Its purpose is simple. Every amount the treaty says is due should be billed, received or chased, with nothing relying on memory.

How Do Deposit and Adjustment Premiums Work?

Deposit and adjustment premiums split the treaty premium into a provisional part and a balancing part. The provisional part is paid during the period, and the balance follows once actual premium is known.

A Munich Re training deck on non-proportional reinsurance describes deposit premiums paid in instalments, usually quarterly or half-yearly in advance. At expiry, the rate is applied to actual premium income, and the difference is the adjustment.

The Reinsurance Association of America glossary says the deposit is adjusted to the higher of actual developed premium or the minimum. The treaty wording always decides.

What Does an Instalment Schedule Look Like?

An instalment schedule lists each amount, due date and status from binding to final adjustment. The illustrative example below covers one excess of loss layer.

Illustrative treaty terms:

• Estimated premium income: 200,000,000, with a rate of 1.5%
• Annual premium on estimate: 3,000,000
• MDP at 90% of the estimate: 2,700,000, payable in four equal quarterly instalments in advance

Each date should allow for any payment period in the clause. Track due date and allowed payment date separately.

How Is the Adjustment Premium Calculated?

The adjustment premium is calculated by applying the treaty rate to the actual premium declared after expiry, then deducting the deposit paid. The type of deposit decides whether a refund is possible.

Illustrative outcomes for the treaty above:

• Actual premium 220,000,000: 220,000,000 × 1.5% = 3,300,000. Less MDP of 2,700,000, the adjustment due is 600,000.
• Actual premium 170,000,000: 170,000,000 × 1.5% = 2,550,000. This is below the MDP, so nothing is due and nothing is refunded.
• Same result under a deposit premium only: the reinsurer would refund 150,000 to the cedent.

The calculation is easy. The hard part is getting the declaration and remembering to ask for it.

Why Are Instalments and Adjustments Missed?

Instalments and adjustments are missed because the schedule lives outside the treaty record. The adjustment also starts with an action nobody owns.

What Happens Legally When Premium Is Late?

When premium is late, the remedy depends on how the premium payment clause is drafted. Without a strong clause, the reinsurer may only have a claim for the debt.

A CMS legal update explains that a payment clause framed as a warranty can, on breach, let the insurer treat itself as discharged from liability. It may instead be drafted as a condition precedent.

Without such terms, late payment rarely amounts to a repudiatory breach under English law. Remedies may then be limited to the premium plus interest.

So the clause wording matters for credit control. Capture the payment terms, not just the amount, when the treaty is bound.

This is not legal advice. Wordings and governing law vary, so check each treaty with your legal team.

How Do You Track Premium Instalments Step by Step?

You track premium instalments by running one cycle from binding to final adjustment. The steps below keep every amount visible.

1. Build the schedule at binding. Take instalment amounts, due dates, payment periods and currency from the treaty terms.
2. Split by participant. Record each reinsurer's share where you lead or manage a panel.
3. Bill ahead of due dates. Issue debit notes or expectations before each instalment falls due.
4. Match receipts. Match cash to the instalment, noting partial payments and offsets.
5. Chase on a timetable. Escalate overdue items by age, from operations to relationship owners.
6. Trigger the adjustment. Request the premium declaration at expiry and calculate the adjustment on receipt.
7. Close the treaty year. Settle the adjustment and confirm nothing remains open.

Step six is where most money is lost. Make it a dated task, not a reminder in someone's calendar.

Who Owns Instalment Tracking?

Instalment tracking is owned by reinsurance finance or credit control, with clear inputs from other teams. Each party has one job in the cycle.

• Treaty administration: Captures instalment and adjustment terms at binding, and records amendments.
• Credit control: Matches receipts, chases overdue items and reports ageing.
• Underwriting: Leads conversations with the cedent when payment issues persist.
• Broker: Collects and remits premium on broker-placed business, often net of brokerage and in batches.

Broker remittances need care. A single payment may cover several treaties, instalments and cedents, so matching must work below the payment level.

Where Does Automation Help?

Automation helps by calculating instalments and adjustments from the treaty terms and showing what is unmatched. Credit control decisions stay with people.

Reinsurance treaty management software holds premium calculation, settlement conditions and settlement calculation alongside treaty calculation rules. Amendments are versioned and every calculation is kept with an audit trail.

That structured treaty data supports accurate instalment schedules and adjustment calculations. Finance teams validate the configuration and the results.

Bordereaux calculation and reconciliation reconciles premium and settlement data and shows reinsurer-wise reconciliation status. The platform identifies the difference, and finance teams determine the cause.

Payments across currencies add another layer. Our article on cross-border reinsurance settlement covers those challenges.

Adjustments also depend on a sound minimum. See why minimum premiums can detach from exposure as portfolios grow.

How Do You Measure Instalment Tracking?

You measure instalment tracking by how much premium arrives on time and how fast adjustments are billed. Report by counterparty and by broker.

What Should Heads of Reinsurance Finance Do Next?

Heads of reinsurance finance should check that every deposit and adjustment is scheduled from the treaty, not from memory. Start with treaties that expired more than a year ago.

• List all treaties with a deposit or MDP and confirm their adjustments were billed.
• Build forward schedules for current treaties from the bound terms.
• Record the premium payment clause type for each treaty.
• Set an automatic declaration request at every treaty expiry.

Key Terms

• Deposit premium: A provisional premium paid during the period and adjusted to actual later.
• Minimum and deposit premium (MDP): A deposit that is also the minimum the reinsurer keeps.
• Adjustment premium: The balancing amount due once actual subject premium is known.
• Premium declaration: The cedent's statement of actual subject premium after expiry.
• Premium payment clause: The treaty term setting when premium must be paid and the effect of late payment.
• Netting: Offsetting premium due against claims payable in one settlement.
