How do I ensure my bordereaux reconciliation workflow with a treaty accounting system is compliant?

To ensure a bordereaux reconciliation workflow with a treaty accounting system is compliant, treat it as a controlled financial reporting process, not just a data-matching exercise. The main goal is to make sure the workflow is accurate, complete, auditable, approved, secure, and aligned with regulatory/treaty requirements.

1) Define the compliance requirements up front

Map the workflow to the rules that apply to your business, such as:

• Treaty terms and wording: reporting deadlines, premium/claim definitions, deductions, commissions, reinstatements, currencies, thresholds.
• Internal control policies: approval limits, segregation of duties, exception handling.
• Accounting standards: local GAAP/IFRS if relevant.
• Regulatory obligations: solvency, reserving, data retention, sanctions screening, tax/VAT where applicable.
• Privacy/security laws: GDPR or local equivalents if bordereaux contain personal data.
• Audit requirements: ability to reproduce reports and decisions later.

2) Establish a controlled data governance process

Your reconciliation is only as compliant as the source data.

• Define a single source of truth for each field.
• Maintain a data dictionary for bordereaux and treaty accounting fields.
• Standardize:
  • policy number
  • risk/insured name
  • effective/expiry dates
  • transaction type
  • currency
  • premiums/claims/fees/commission
• Validate file formats and mandatory fields at ingestion.
• Use version control for bordereaux templates and mapping rules.

3) Build reconciliation rules that are documented and repeatable

Document the logic used to compare bordereaux to the treaty accounting system.

Typical controls:

• Completeness checks: all expected bordereaux received.
• Accuracy checks: field-level comparisons and tolerances.
• Cutoff checks: correct accounting period.
• Duplication checks: duplicate policies/transactions.
• Movement checks: prior period adjustments, reversals, endorsements.
• Currency conversion checks: approved FX source and rate date.
• Computation checks: premium, commission, taxes, profit commission, losses.

Keep the rule set:

• approved by finance/accounting
• reviewed by underwriting/claims if relevant
• tested before go-live and after changes

4) Implement segregation of duties

A compliant process should separate responsibilities where possible:

• Prepare bordereaux mapping/reconciliation
• Review exceptions
• Approve write-offs, adjustments, and journals
• Post accounting entries
• Administer system access

This helps prevent self-approval and reduces fraud/error risk.

5) Set up an exception management process

Not every discrepancy should be forced to “match.”

For exceptions:

• classify them by type and materiality
• assign owners
• require documented resolution
• define SLA/timeframes
• track status to closure
• maintain evidence of approvals for manual adjustments

Examples:

• timing difference
• data entry error
• treaty interpretation issue
• missing bordereaux
• claim not yet reported
• FX mismatch

6) Maintain a full audit trail

A compliant system should let an auditor trace everything end-to-end.

Retain:

• original bordereaux files
• imported/normalized data
• reconciliation results
• rule versions
• manual overrides and their approvals
• journal entries and posting references
• user IDs, timestamps, and change logs
• supporting correspondence for disputes or corrections

Ensure logs are:

• tamper-evident
• retained for the required period
• searchable and exportable

7) Apply materiality and tolerance thresholds carefully

Use thresholds only if they are:

• formally approved
• consistent with policy/treaty terms
• documented in the workflow
• periodically reviewed

Don’t use tolerances to hide recurring issues. Track patterns and escalate chronic differences.

8) Validate system controls and access management

The treaty accounting system should have strong control features:

• role-based access control
• MFA where required
• restricted admin access
• workflow approvals
• password/session policies
• interface controls for imports/exports
• change management for formulas, mappings, and reports

Periodically review access rights and remove stale users.

9) Test the workflow regularly

Perform:

• UAT before implementation
• periodic control testing
• sample-based reconciliations
• back-testing of prior periods
• independent review/internal audit testing

Testing should confirm the workflow works correctly under:

• partial files
• corrections
• reversals
• multi-currency scenarios
• late bordereaux
• treaty amendments

10) Document policies and procedures

You should have written procedures covering:

• bordereaux intake
• validation
• reconciliation logic
• exception handling
• approvals
• journal posting
• data retention
• escalation routes
• periodic review and sign-off

If it isn’t documented, it’s hard to defend in an audit.

11) Monitor ongoing compliance

Use KPIs/KRIs such as:

• bordereaux received on time
• % matched automatically
• open exceptions older than SLA
• number of manual adjustments
• recurring error types
• unreconciled balance by treaty/entity/period

Review these regularly at finance/control meetings.

12) Engage stakeholders early

Compliance is usually cross-functional.

Involve:

• accounting/finance
• underwriting
• claims
• actuarial
• operations
• IT/security
• legal/compliance
• internal audit

This helps ensure treaty wording, operational practice, and system setup all align.

Practical compliance checklist

Use this quick checklist:

• Treaty terms mapped to reconciliation rules
• Bordereaux templates standardized and version-controlled
• Mandatory fields validated on import
• Matching logic documented and approved
• Segregation of duties enforced
• Exceptions tracked to resolution
• Manual adjustments approved and logged
• Audit trail retained
• Access controls reviewed
• Regulatory retention/privacy rules met
• Periodic control testing performed
• Management review evidenced

If you want to be especially safe

Ask for an internal controls review or external assurance review of the workflow. For higher-risk environments, some firms also align the process to:

• SOX-style controls
• COSO internal control principles
• ISO 27001 for information security

If you’d like, I can also help you create:

1. a compliance checklist,
2. a SOP for bordereaux reconciliation, or
3. a control matrix mapped to treaty accounting risks.
