Reinsurance Statement of Account Without Manual Rework

Reinsurance Statement of Account: Producing Accurate Technical Accounts Without Manual Rework

Last reviewed: November 2026

The Q3 account went out on time. It came back three weeks later, because the commission rate had changed at a mid-year amendment that never reached the spreadsheet.

Short answer: An accurate reinsurance statement of account comes from treaty terms held as versioned data, applied by consistent calculation rules. Pre-issue checks then catch errors before reinsurers do, so accounts are agreed rather than reworked.

Key Takeaways

• The account is only as good as the terms behind it. Most rework starts with an out-of-date share, rate or amendment.
• Version every amendment. Each account must use the terms in force for its period.
• Check before you send. A few pre-issue tests prevent most reinsurer queries.
• Reverse, never overwrite. Corrections should leave the original visible for audit.

What Is a Reinsurance Statement of Account?

A reinsurance statement of account is the periodic account for a treaty showing every item for the period and the balance due. Proportional treaties commonly account quarterly, by section and currency.

The cedent, or a broker on its behalf, usually prepares it. Each reinsurer then checks it against the treaty and its own records before agreeing.

Agreement matters as much as accuracy. Under ACORD's GRLC model, settlement follows once the technical account is business accepted, so every query delays the cash.

Is a Statement of Account the Same as a Technical Account?

A statement of account and a technical account are often used as the same thing, although usage varies by market. ACORD gives the technical account a precise digital definition.

Under ACORD's GRLC standards, a technical account is an accounting transaction shared between trading partners. Each covers one contract and section, with one sender, one receiver and one settlement due date.

It also carries one original currency and one settlement currency. Multi-currency treaties therefore need a separate technical account for each currency.

ACORD lists supported transaction types including premium, deposit premium, adjustments, reinstatement, account statement, claims and commission. That range shows how much a single treaty can generate.

What Goes Into a Quota Share Statement of Account?

A quota share statement of account combines premium, commission, claims and deposit movements into one balance. The layout below is typical, although each treaty's wording governs.

Excess of loss accounts look different. They usually show deposit premium instalments, adjustment premium, reinstatement premium and claim recoveries instead.

What Does a Worked Account Look Like?

A worked account shows how quickly small term errors move the balance. Take a 30% quota share for one quarter (illustrative figures).

Now suppose a mid-year amendment cut the commission to 30%. Commission falls to 900,000, the balance rises to 586,000, and the issued account is wrong by 60,000.

That one stale rate means a reversal, a new account and a second agreement cycle. Multiply it across reinsurers and sections, and the quarter's work doubles.

Why Do Statements of Account Need Manual Rework?

Statements of account need rework because the inputs change faster than the spreadsheets that hold them. Each cause below forces a reissue.

Our article on no single source of truth for treaty terms explains why scattered terms cause these errors. Calculation failures are covered in billing the treaty correctly.

How Do You Produce an Accurate Statement of Account?

You produce an accurate statement of account by fixing the terms first and checking the result before issue. The process runs in seven steps.

1. Hold terms as data. Capture structure, shares, commission formulas and settlement conditions in one place.
2. Version amendments. Record each amendment with its effective date, keeping earlier versions.
3. Reconcile the bordereau. Confirm premium and claims data before any calculation runs.
4. Calculate by rule. Apply the terms in force for the period, section and currency.
5. Split by reinsurer. Apply each reinsurer's participation to produce its own account.
6. Check and approve. Run pre-issue checks, then have a second person approve.
7. Issue and track. Send each account, track agreement, and correct only by reversal.

Step two prevents the most expensive errors. An amendment that applies from 1 July must not change the Q1 and Q2 accounts.

Which Checks Should Run Before an Account Is Issued?

The checks that matter test the terms, the data and the result. Each one takes minutes and saves a reissue cycle.

Corrections need the same discipline. ACORD guidance says a reversal technical account carries the original amounts with the sign reversed, so both remain visible.

Do Market Messaging Standards Remove the Rework?

Market messaging standards reduce rework in transmission, but they do not fix wrong terms. A technical account sent digitally can still carry a stale commission rate.

ACORD's Ruschlikon initiative applies GRLC standards to technical accounting, claims and settlement between brokers and (re)insurers. It makes accounts easier to receive, check and agree.

The accuracy of each figure still depends on the treaty data behind it. Standards and structured terms work best together.

Where Does Automation Help?

Automation helps by turning treaty terms into structured data and consistent calculations. It does not decide commercial terms or replace accounting judgement.

Reinsurance treaty management covers treaty structure, participation and share configuration, and commission formula configuration. It also handles premium and settlement calculation, amendments and versioning, calculation history and an audit trail.

Those are the inputs a statement of account depends on. Your accounting team still validates the configuration and the results before any account is issued.

Upstream, bordereaux calculation and reconciliation reconciles the premium and claims data feeding the account.

Which Metrics Show Statement Quality Is Improving?

The useful metrics show how often accounts are agreed first time. Track them by treaty and counterparty each quarter.

What Should Heads of Reinsurance Accounting Do Next?

Heads of reinsurance accounting should start with the treaties that are reissued most often. Their rework causes usually point to a few stale terms.

• List last year's reissued accounts and the cause of each.
• Move shares, commission formulas and amendments into structured, versioned data.
• Introduce the five pre-issue checks before the next quarter.
• Require reversal and replacement for every correction.

Key Terms

• Statement of account: The periodic treaty account showing all items and the balance due.
• Technical account: In ACORD GRLC standards, a digital accounting transaction for one contract and section.
• Premium reserve deposit: Premium retained by the cedent as security and released later under treaty terms.
• Ceding commission: An allowance paid by the reinsurer to the cedent for acquisition and administration costs.
• Treaty versioning: Recording each amendment with an effective date while keeping earlier versions.
• Reversal: A correcting entry that cancels an original account with opposite signs.
