Lease Accounting Agent
Account for lease contracts - from contract extraction to disclosure note.
Extracts key data from lease contracts, classifies per IFRS 16 or HGB, calculates right-of-use assets and lease liabilities, creates monthly postings and prepares notes disclosures.

What This Agent Does
Lease accounting has been one of the most complex areas of financial accounting since IFRS 16. Every lease must be recognised as a right-of-use asset and lease liability. The present value of lease payments, the incremental borrowing rate and monthly postings (interest expense, principal, depreciation) must be correctly calculated. On contract modifications, the entire calculation is reset.
The Decision Layer breaks lease accounting into nine decision steps. The LLM extracts key data from PDF lease agreements. Classification (finance lease vs. operating lease) is rule-based for standard cases; for borderline cases the human decides. The present value is calculated per IFRS 16. The incremental borrowing rate requires human estimation. Monthly postings are generated automatically.
The result: significant time savings for companies with many lease contracts. Crowe reports 3-5 FTE hours saved per reporting period for 50+ contracts. Disclosure notes are prepared by LLM.

Decision Record and Right to Challenge
Every decision this agent makes or prepares is documented in a complete decision record. Affected parties (employees, suppliers, auditors) can review, understand, and challenge every individual decision.
Prerequisites
- Lease contract repository (digitised contracts as PDF)
- IFRS 16-capable ERP system or lease management software
- Current market data for incremental borrowing rate (IBR)
- CPI index data for index-based adjustments
- GL interface for posting transfer
Governance Notes
Mixed decision distribution (1H / 5R / 2A / 1 R/H). Human decision for incremental borrowing rate (estimation) and classification of borderline cases. IFRS 16 and HGB as direct accounting standards. GoBD-compliant: every calculation is archived with input values, applied rate and calculation result.
Balance-sheet-relevant and audit-sensitive: right-of-use assets and lease liabilities are material balance sheet items. The statutory auditor reviews the completeness of the lease portfolio, classification and valuation. Paragraph 203 StGB relevant: lease contracts contain terms and trade secrets.
§203 StGB-relevant data is encrypted end-to-end and never passed to AI models in plain text.
Process Documentation Contribution
Infrastructure Contribution
The contract extraction by LLM is a reusable pattern for the Contract Compliance Agent and all agents that need data from unstructured contracts. The present value calculation and amortisation schedule are standard financial formulas also used by the Revenue Recognition Agent and Provisions Agent. The modification logic (change detection, recalculation) is the pattern for all agents that must react to contract changes. Builds Decision Logging and Audit Trail used by the Decision Layer for traceability and challengeability of every decision.

Frequently Asked Questions
Does the agent support both IFRS 16 and HGB?
Yes. The classification distinguishes between IFRS 16 (all leases on-balance) and HGB (economic ownership determines). The rule engine is configured per applicable accounting standard. Parallel valuation for HGB/IFRS statements is possible.
How are short-term leases and low-value asset leases handled?
IFRS 16 allows the exemption for short-term contracts (under 12 months) and low-value assets (under approx. USD 5,000). The agent identifies these automatically and applies the simplified accounting.
What happens with renewal options?
The agent assesses renewal options rule-based (reasonably certain vs. not reasonably certain). For ambiguity, it escalates to human decision. When an option is exercised, it recalculates the modification automatically.
