In a co-lending arrangement under RBI's CLM-2020 circular, every loan is co-originated between the bank (80%) and the NBFC (20%). Every disbursement, every EMI receipt, every prepayment, every penal charge — each generates a transaction that must be split between the two partners in exactly the agreed ratio, reflected in both CBS systems, and reconciled to zero difference by the end of each business day. When manual reconciliation is attempted across 2,000-plus co-lending accounts, the daily reconciliation breaks down within weeks, the exception backlog grows, and the partnership's financial integrity becomes impossible to verify. The Co-Lending Ops Agent AI reconciles every transaction automatically, flags every exception before end of business, and keeps the reconciliation current.
Why co-lending reconciliation is structurally harder than normal loan reconciliation
A standard loan exists in one system — the institution's own CBS. Its transactions are recorded once and do not need to be matched against another institution's records. A co-lending loan exists in two systems simultaneously — the bank's core banking system and the NBFC's CBS — and every transaction must appear in both at the agreed split, on the same value date, or a reconciliation item is created. The structural sources of reconciliation breaks in co-lending are: value date differences (the bank books a transaction on T and the NBFC books it on T+1, creating a one-day float mismatch); rounding differences (the 80:20 split applied to an odd EMI amount produces a one-rupee rounding gap that neither system resolves automatically); interest calculation method differences (the bank uses a daily reducing balance method while the NBFC uses a monthly reducing balance method, producing systematic interest discrepancies); and payment routing delays (the borrower pays through the NBFC's collection channel, the NBFC receives and applies the payment, but the bank's 80% share is not transferred until the next settlement window).
Each of these is a known, predictable source of reconciliation breaks. The Co-Lending Ops Agent AI identifies each type, categorises the break, and resolves what can be resolved automatically — rounding differences, value date offsets — while routing genuine discrepancies to the finance team for resolution.

The transaction types the Co-Lending AI reconciles
| Transaction Type | Split Rule | Common Break Cause | Auto-Resolution Available |
|---|---|---|---|
| EMI receipt — full | 80:20 ratio · NBFC collects and transfers 80% to bank | Rounding (±₹1–2) on odd EMI amounts | Yes — rounding ≤₹2 |
| EMI receipt — partial | Partial applied to interest first, then principal · Split after application | Interest calculation method differences (daily vs monthly reducing balance) | Partial — if method difference known |
| Prepayment — partial | Prepayment reduces principal · 80:20 share of principal reduction | Prepayment date vs application date — bank books on receipt date, NBFC on borrower-authorised date | Partial — date offset auto-categorised |
| Prepayment — full foreclosure | Full outstanding at 80:20 + foreclosure charge split | Foreclosure charge split formula — some agreements specify flat charge, others pro-rata by share | No — requires agreement review |
| Disbursement | NBFC disburses 20%, bank disburses 80% simultaneously | Bank's disbursement delayed by internal approval — NBFC disburses, bank records T+1 | Auto-flagged · Date offset expected |
| Penal charges | Penal charges split 80:20 — or per agreement if different | NBFC levies penal charges per its own policy; bank may not levy penal on its share — creates asymmetric accrual | No — agreement clause review required |
| Interest accrual (monthly) | Monthly interest split per outstanding balance ratio | Daily vs monthly reducing balance methodology produces accumulating difference over the year | Partial — systematic difference flagged for annual true-up |
| NPA provisioning | Each partner provisions on their own book independently — no shared computation | NBFC classifies NPA at 90 DPD; bank may classify at a different date (different DPD counting method) | No — regulatory compliance for each partner separately |
The exception resolution framework: from detection to closure
Auto-resolved: the party with the rounding shortfall is credited ₹1–2 in the next settlement cycle
When 80:20 splits produce a fractional rupee that cannot be distributed, the rounding convention (typically: NBFC takes the fraction in its favour, bank rounds down) is applied automatically. The ₹1–2 accumulated rounding difference is trued up in the monthly settlement summary rather than creating a daily reconciliation item.
→ Auto-resolved · Accumulated in monthly true-up · No human actionAuto-categorised as a date offset · Resolved when the lagging partner posts the transaction
The Co-Lending AI detects that the same transaction (same amount, same account) appears in one partner's records with a one-day offset. It is categorised as a pending match rather than a genuine break. The partner with the later booking is sent an automated reminder. If the transaction does not appear in both systems within 48 hours, it escalates to a genuine exception requiring investigation.
→ Auto-categorised · Partner reminder sent · Escalates at 48 hours if unresolvedThe largest reconciliation break by rupee amount — borrower pays the NBFC, bank's 80% share is in transit
When a borrower makes a prepayment through the NBFC's channel, the NBFC holds 100% of the payment until it transfers the bank's 80% share in the next settlement window. During this gap, the NBFC's books show the full amount received and the bank's books show nothing. This is not a break — it is a timing difference with a known resolution. The Co-Lending AI tracks the settlement window and confirms the bank's 80% is transferred within the agreed period (typically 2 business days).
→ Bank's share tracked to settlement window · Escalate if not transferred within 2 business daysSystematic difference that grows through the year · Resolved at annual true-up
When the bank computes interest on a daily reducing balance and the NBFC uses monthly, the interest accruals diverge by a small but accumulating amount over the year. The Co-Lending AI tracks this systematic difference, quantifies it monthly, and produces the annual true-up calculation at year-end that resolves the accumulated divergence between the two partners' interest books.
→ Tracked monthly · Quantified · Annual true-up calculation generatedA co-lending partnership whose reconciliation is current is a partnership that can be trusted — one whose reconciliation is backlogged is a partnership built on unverified numbers
The bank's relationship manager and the NBFC's CFO need to be able to answer one question about their co-lending portfolio at any time: "Are our books in agreement?" In a manually reconciled partnership, the honest answer to that question is often "we think so, as of three weeks ago." In a Co-Lending Ops AI-managed partnership, the answer is "yes, as of yesterday's close, with three transactions worth ₹4,600 under review." The difference between those two answers is the difference between a partnership that can scale and one that will collapse under the weight of its own unreconciled backlog.
