MPBF in Working Capital Assessment: A CCP Study Guide

For anyone preparing for the IIBF Certified Credit Professional (CCP) exam, understanding MPBF in working capital assessment is one of the most tested and most misunderstood topics in the credit appraisal syllabus. MPBF, or Maximum Permissible Bank Finance, is the ceiling a bank sanctions for working capital limits, calculated using the lending norms first recommended by the Tandon Committee in 1974. Even though the Reserve Bank of India withdrew the mandatory prescription of the MPBF methodology in 1997, most public sector banks and several private banks still use some version of these norms — alongside the turnover method and the cash budget method — as an internal benchmark for assessing borrower limits. This article walks through how MPBF is calculated, how it interacts with drawing power, and where candidates most often go wrong in exam numericals and viva questions.

🏦 What Is MPBF and Where Did It Come From?

MPBF in working capital assessment traces back to the Study Group headed by Prakash Tandon, which submitted its report in 1974 at a time when Indian banks financed working capital almost entirely through open-ended cash credit accounts, with very little discipline on how much a borrower actually needed. The Tandon Committee's core idea was simple: a bank should finance only the gap between a borrower's current assets and its current liabilities other than bank borrowings — a figure it called the Working Capital Gap (WCG) — and a meaningful slice of that gap should be funded by the borrower's own long-term sources, not the bank.

This shifted working capital lending from a purely demand-driven facility to a properly appraised, projection-based limit that forms part of the broader credit appraisal process every bank credit officer learns. The committee's recommendations were refined further by the Chore Committee in 1979, which pushed banks toward the stricter of the two lending methods it had proposed. Together, these two committees still shape how Indian banks think about working capital limits, even decades after the RBI stopped mandating any single method.

📊 The Three Methods of Lending Under MPBF

The Tandon Committee proposed three ways of arriving at MPBF, each pegging a different share of current assets to long-term funding. Under the First Method of Lending, MPBF equals 75% of the Working Capital Gap, so the borrower funds the remaining 25% of the gap from net working capital, producing a fairly lenient effective current ratio of roughly 1.17:1. Under the Second Method of Lending — the one the Chore Committee pushed banks to adopt for larger borrowers — MPBF is still 75% of current assets minus current liabilities other than bank borrowings, but the margin is now computed on total current assets rather than only the gap, which raises the required current ratio to about 1.33:1 and forces a materially larger long-term contribution from the borrower. A rarely-used Third Method goes further still, requiring "core" current assets (the permanent, non-fluctuating portion of stock and receivables) to be entirely funded from long-term sources before the 75% rule is applied to the rest. These norms sit alongside the bank's own credit policy, which decides which method applies to which borrower segment.

💰 MPBF, Drawing Power and the Working Capital Gap

MPBF is a sanctioned outer ceiling, decided once at the time of assessment or annual renewal. What a borrower can actually withdraw from a cash credit account day to day is a different figure entirely: the Drawing Power (DP), calculated from the latest stock and book-debt statement after applying the agreed margin. The account's operative limit is always the lower of the sanctioned MPBF and the current DP — a borrower cannot draw beyond DP even if MPBF headroom is available, and any drawing beyond DP is treated as an irregularity that has consequences under income recognition and asset classification norms.

⚠️ Common Mistake: Candidates often assume MPBF and Drawing Power are the same number. They are not — MPBF is the sanctioned ceiling; DP is the actual, periodically-refreshed entitlement based on real stock and receivables.

This is precisely why timely, accurate stock statements matter so much operationally — they feed directly into the DP calculation and, over time, into the credit officer's assessment of whether the account needs closer credit monitoring and supervision of advances. Facilities are also structured through the bank's overall credit delivery arrangements, which decide whether the limit is routed as a single cash credit account, a multiple banking arrangement, or a consortium.

🧮 MPBF vs the Turnover Method: Which Applies When

Not every borrower is assessed using the Tandon Committee's balance-sheet-driven methods. Following the Nayak Committee's 1993 recommendations, small and medium borrowers seeking working capital limits within the RBI-specified turnover-method threshold are assessed far more simply: the working capital requirement is taken as 25% of projected annual turnover, of which the bank typically finances 20% of turnover and the borrower contributes the remaining 5% as margin. This spares smaller units the burden of preparing the detailed projected balance sheets that MPBF assessment demands, while still tying the limit to a verifiable, turnover-based benchmark.

Larger borrowers, and those whose current asset and liability patterns are complex enough that a flat turnover ratio would misstate their real need, continue to be assessed under MPBF's Tandon-style methods, with margin requirements forming just one part of the bank's broader promoter contribution and margin norms framework applied at appraisal. The choice of method also interacts with how the borrower is categorised in the first place — see our chapter on types of borrowers and types of credit facilities for how limits are structured across fund-based and non-fund-based lines. Large, listed corporates increasingly supplement bank-assessed working capital with market instruments such as commercial paper settled through the depository system — a topic covered from the markets side in our JAIIB piece on stock exchanges and depositories in India — but MPBF-style assessment remains the backbone for fund-based bank limits.

💡 Exam Tip: If a question gives you turnover figures and asks for the working capital limit under the simplified method, remember the split is 25% of turnover as total requirement, 20% bank finance, 5% borrower margin — not 75:25.

📌 Common MPBF Mistakes and Exam Traps

The single most frequent numerical error is applying the 25% margin to the wrong base — using total current assets when the question specifies the First Method (where the margin applies only to the Working Capital Gap), or vice versa for the Second Method. A close second is forgetting the "other than bank borrowings" qualifier when computing current liabilities, which inflates the gap and overstates MPBF. Candidates also frequently confuse the turnover method's eligibility threshold with MPBF-eligible borrowers, or assume every bank still legally must use Tandon-style norms, when in fact the Reserve Bank of India's 1997 deregulation made the entire choice of methodology a bank-level policy decision.

On the practical side, MPBF limits do not stay static once sanctioned — they are revisited at each renewal, informed by credit audit and loan review mechanism findings, and cross-checked against the borrower's capital adequacy and repayment track record before renewal. Treat MPBF as a living assessment tied to the account's actual performance, not a one-time formula exercise, and most of these exam traps resolve themselves.

📌 Remember: First Method margin is on the Working Capital Gap; Second Method margin is on total Current Assets. That single distinction accounts for most MPBF numerical errors in the exam.

❓ Frequently Asked Questions

MPBF in working capital assessment remains a core skill for any credit officer, and a heavily tested one for CCP candidates, precisely because it forces you to connect balance-sheet analysis, margin norms and day-to-day account monitoring into one coherent picture. Once you can move fluently between the First Method, Second Method, cash budget method and turnover method — and explain why drawing power is not the same as MPBF — most exam numericals stop being a trap.
