Margin Call Dispute Detection — Dataset
AAL-D-002 is the second benchmark dataset in the AI Alpha Labs evaluation suite. Where AAL-D-001 tested trade confirmation exception identification, AAL-D-002 tests a downstream, mathematically heavier workflow: margin call dispute processing. Each case presents a counterparty margin call notice alongside an internal calculation. Models must determine whether a dispute exists, classify it within a 17-category taxonomy, compute the correct call amount, recommend an action, determine whether the undisputed amount should be paid, and flag whether escalation is required. The dataset covers bilateral OTC CSA portfolios, exchange-cleared positions, and securities lending agreements.
Coverage
Six instrument types: interest rate swaps, FX forwards and NDFs, cross-currency swaps, listed futures, equity total return swaps, credit default swaps, and securities lending. Seventeen dispute categories including DIS-PRICE, DIS-THRESH, DIS-HAIRCUT, DIS-ELGBLTY, DIS-FX, DIS-NETTING, DIS-SIMM, DIS-STALE, DIS-DUPE, DIS-SETTLED, DIS-DIR, and DIS-CSA. Difficulty ranges from easy (clean matching calls, simple single-category disputes) to complex (multi-leg portfolios, direction inversions, collateral eligibility violations, SIMM version mismatches).
Workflow complexity
AAL-D-002 is materially harder than AAL-D-001. Correct handling requires applying MTA and rounding conventions, computing threshold-adjusted exposure, applying haircuts to collateral, reconciling netting sets, determining undisputed-payment obligations, and recognizing duplicate or stale calls. The arithmetic burden is substantially higher — this is deliberate, to test whether the arithmetic weakness confirmed in AAL-D-001 persists when math is the primary deliverable.
Scoring
Each case specifies per-field scoring criteria: dispute detection (binary), category identification, field identification, correct call amount (numeric match within tolerance), disputed amount, undisputed payment flag, and escalation requirement. Tolerances are tiered by call size: ±$1k for calls under $500k, ±$5k for calls $500k–$5M, ±$10k for calls above $5M.
Sample case preview
Case AAL-D-002-017 · Bilateral OTC IRS Portfolio · Independent Amount Dispute. Counterparty margin call notice: $5,200,000.00 USD. Internal calculation: $4,850,000.00 USD. Dispute amount: $350,000.00. The counterparty applied a 10% independent-amount factor to the entire notional of $350,000,000; the CSA limits the IA to the in-the-money subset of $180,000,000. Ground truth flags dispute category DIS-IA-METHODOLOGY (Independent Amount calculation), computes correct call amount as $4,850,000.00, recommends action PAY-UNDISPUTED, sets undisputed amount as $4,500,000.00, and flags escalation-required as false. Scoring criteria: dispute category must be exact among 17 categories; correct call amount must match within $1,000.00; undisputed amount must match within $500.00; action and escalation boolean must be exact.
