Bank M&A Ledger Reconciliation System using AutoGen Multi-Agent Simulation

When major banking institutions execute portfolio acquisitions (such as Santander integrating Webster Bank systems), merging legacy general ledgers and core deposit accounts takes months of manual reconciliation and auditing. Discrepancies in ledger naming conventions, chart-of-accounts mappings, and accrued interest logic often cause millions in post-merger accounting drift. In this challenge, you will implement a multi-agent conversational simulation using Microsoft AutoGen. Specialized agents representing the Acquiring Bank, Target Bank, and Independent Auditor will interact autonomously to verify balance sheet migration accuracy and resolve chart-of-accounts discrepancies.

Delivery guide

How work is evaluated

Evaluation

Evaluates reconciliation accuracy and agent consensus resolution.

Datasets

Challenge datasets

Public datasets, plus the private datasets you have access to.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

consensus_achieved

Verifies that all three agents reached explicit agreement

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

reconciliation_accuracy

Percentage of balance sheet items correctly mapped without residual error • target: 100 • range: 0-100

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
