Over the years I have heard a particular phrase used loosely in credit discussions and even in a few audit notes: as per IBA norms for working capital. It is usually said with confidence and it is usually only half correct. The Indian Banks Association does have a real and substantial influence on how working capital finance is documented and administered in this country. What it does not do and what it has never claimed to do, is fix the arithmetic by which a bank decides how much working capital a borrower may draw. That arithmetic belongs to the Reserve Bank of India and to the committees it has appointed over the last five decades. For a stock and receivables auditor, understanding exactly where the IBA writ runs, and where it does not, is not a matter of pedantry. It changes what the auditor reads, what the auditor relies upon and how the auditor frames the report.

Let me set out the position as I understand it and then connect it to the work we actually do on the ground.

What the IBA is, and what it is not

The Indian Banks Association was formed in 1946 as a voluntary, representative body of banks. It is not a statutory regulator. It does not have the power to issue binding directions to banks in the way the Reserve Bank does under the Banking Regulation Act. What it has built, over time, is something quieter but very useful to the system: a body of standardised documentation, model codes and common practices that member banks adopt so that the same kind of transaction is papered the same way across the industry. When you see a deed of hypothecation, a consortium agreement, or an inter-se agreement between lenders that looks almost identical regardless of which bank drafted it, you are usually looking at an IBA model document that the banks have agreed to adopt. Many of these model formats were themselves devised to give effect to directions issued by the Reserve Bank. So the IBA sits, in a sense, between the regulator and the operating banks, translating regulatory intent into uniform paperwork.

Where the lending methodology actually comes from

The methods by which a bank assesses a borrower working capital requirement have a long regulatory history, and none of the principal milestones are IBA documents.

The Tandon Committee, constituted by the Reserve Bank in 1974, gave us the concept of Maximum Permissible Bank Finance and the two methods of lending that practitioners still refer to, along with the now familiar discipline of the borrower funding at least a quarter of current assets so that a current ratio of around 1.33 to 1 is maintained. The Chore Committee in 1979 pushed banks to reduce a borrower over-dependence on cash credit and introduced the idea of carving out a working capital term loan where borrowing exceeded the permissible level. The Nayak Committee in the early 1990s gave us the turnover method, under which working capital limits for smaller units are assessed at a minimum of twenty percent of projected annual turnover, with the borrower expected to bring in a margin of five percent. In its credit policy of 1997 the Reserve Bank withdrew the compulsory MPBF prescription and left banks free to evolve their own systems, while retaining the turnover method as a floor for smaller borrowers. More recently, the Reserve Bank guidelines on the loan system for delivery of bank credit, issued on 5 December 2018, required that for borrowers with aggregate fund-based working capital limits of ₹150 crore and above, a minimum portion of the limit be carved out as a working capital loan rather than left as freely operable cash credit, with the stated purpose of instilling greater credit discipline and reducing the perpetual roll-over of cash credit.

I set these out not to give a history lesson but to make a single point. Every one of them is a Reserve Bank measure. The IBA participated, as the representative body of banks, in the consultations around several of them, but the directions themselves are the regulator. When a sanction letter computes a limit on the turnover method or splits a limit into a loan component and a cash credit component, it is following the Reserve Bank, not the IBA.

What the IBA actually contributes to working capital lending

So what is the IBA real contribution and why should an auditor care about it?

The first and most important contribution, from our point of view, is the standardised security documentation. Working capital against stock and book debts is almost always secured by hypothecation. The deed of hypothecation that creates the bank charge over the borrower current assets is, in most banks, drawn from an IBA model format. That single document defines the entire field on which a stock auditor operates. It describes what is hypothecated, whether the charge is exclusive or shared, the borrower obligation to keep the hypothecated stock insured against specified risks, the borrower obligation to submit periodic stock and book-debt statements, and the bank right to inspect the hypothecated assets and the borrower records. When we verify existence of stock, ownership of stock, adequacy of insurance, or the integrity of the stock statements on which drawing power is computed, we are in substance testing whether the borrower has honoured the very covenants written into that IBA-pattern deed.

The second contribution lies in consortium and multiple banking arrangements. Where several banks finance one borrower, the IBA has finalised model consortium documents, joint deeds of hypothecation and inter-se agreements among the lenders, again to give uniform effect to the Reserve Bank framework for such lending. After the Central Vigilance Commission raised concerns some years ago about frauds slipping through where banks lent to the same borrower without sharing information, the Reserve Bank tightened its instructions on lending under consortium and multiple banking arrangements. The format in which banks obtain a declaration from the borrower about facilities enjoyed from other banks, and the format in which they exchange information about the conduct of the account at least once a quarter, were finalised in consultation with the IBA. For a stock auditor working on a consortium account this is directly relevant. The scope of the charge, whether the bank holds a first, second, or pari passu charge, and whether the consortium has agreed to rely on a single common stock audit report rather than commission one each, all flow from this documentation.

The third contribution is the broader body of model codes and panels. The IBA Code of Banking Practice and its various model guidelines sit in the background of how accounts are administered and several banks draw their panels of stock auditors and specialised monitoring agencies from IBA-maintained lists. None of this changes the lending arithmetic but it shapes the environment in which our engagement is set up and our report is read.

Why this matters in a stock and receivables audit

Here I want to be careful about something I consider fundamental and which is too often forgotten. A stock and receivables audit is not an audit in the statutory sense. It is a special purpose assignment. We are not expressing a true and fair opinion on financial statements under the Companies Act. We are engaged by a bank to verify, as at a date and for a defined scope, that the security underlying a working capital facility exists, belongs to the borrower, is reasonably valued, is adequately insured, and supports the drawing power being permitted. The Institute of Chartered Accountants of India Guidance Note on Reports or Certificates for Special Purposes governs how we should accept, conduct, document, and report such an engagement, and it is the engagement letter, not the statutory audit framework, that defines our boundaries.

Once that framing is clear, the relevance of the IBA documentation becomes obvious. The hypothecation deed is the contractual source of almost everything we test. Let me put a simple illustration to it.

Suppose a manufacturing borrower enjoys a cash credit limit of ₹500 lakhs, secured by hypothecation of stock and book debts under the bank standard deed. The sanction stipulates a margin of 25 percent on paid stock and 40 percent on book debts up to 90 days, with older debts and unpaid stock excluded. As on the audit date the borrower stock statement yields the following.

So the drawing power works out to ₹333 lakhs, against a sanctioned limit of ₹500 lakhs. The account may be drawn only up to the lower of the two, that is ₹333 lakhs.

Now consider what each line in that computation rests upon. The exclusion of stock held against unpaid creditors exists because the hypothecation creates a charge in the bank favour, and stock not yet paid for is, in substance, still subject to the supplier claim. The exclusion of debts over 90 days reflects the sanction terms, but the auditor ability to insist on seeing the ageing, and to test it, flows from the borrower covenant in the deed to maintain and produce book-debt statements. The requirement that the stock be insured for its full value against fire and allied perils is a covenant in the same deed, and if the auditor finds the stock under-insured, that is a reportable deviation from the security documentation, not merely a commercial observation. Each of these threads runs back to the IBA-pattern deed and the sanction that sits on top of it.

The loan-system discipline shows up differently. If the same borrower facilities were large enough to attract the loan-component requirement, a part of the limit would have to be availed as a working capital loan rather than as freely drawable cash credit. For the stock auditor the lesson is that the drawing power computed against security, and the manner in which the limit is delivered, are two separate questions. We compute and report on the former. We do not certify compliance with the loan-system split, which is the bank administrative responsibility, though noticing and flagging an obvious inconsistency is good practice.

The consortium account, where the documentation bites hardest

In a consortium account the IBA documentation matters even more directly. If the bank holds a pari passu first charge on current assets along with three other banks, the stock we are verifying secures the whole consortium and the drawing power discipline has to be read against the aggregate facilities rather than one bank limit in isolation. Whether we report only to our appointing bank or our report is shared with the consortium and whether the consortium has agreed to accept a single common stock audit, are matters settled by the inter-se agreement and the lead bank arrangement. I have seen engagements go wrong because the auditor assumed an exclusive charge where the security was in fact shared and computed drawing power as though the borrower entire stock backed one bank limit. Reading the charge documents at the outset prevents that error and the place to read them is the consortium and hypothecation paperwork that the IBA has standardised.

Reporting and documentation discipline

This brings me to the reporting and documentation side, where the ICAI framework does the heavy lifting. Our working papers should record what documents we examined, including the sanction letter and the relevant hypothecation and consortium documents, and the Standards on Auditing, in particular the discipline of audit documentation, apply with appropriate modification to a special purpose engagement. The reporting language should be factual and measured. We state what we verified, the date as at which we verified it, the basis on which drawing power was computed, the deviations we found, and the limitations on our work. We do not opine on the borrower solvency, we do not certify the adequacy of insurance as an insurance professional would, and we do not pronounce on whether the bank lending decision was sound. Where the security falls short, where the stock statement does not reconcile with the books, or where the charge is shared in a way that affects the drawing power, we report the fact plainly and let the bank draw its own conclusions. The ICAI Code of Ethics requires us to hold that line even when there is pressure to soften it, and the institute disciplinary record has consistently treated the dilution of a finding to please an interested party as a serious lapse of professional conduct.

The practical takeaway

After all of this, the takeaway is a simple reorientation. When a borrower or even a bank officer tells you that something is as per IBA, pause and ask what they mean. If they mean the method of assessing the limit, the answer almost always lies in a Reserve Bank committee or circular, and you should read the sanction letter to see which method was actually applied. If they mean the security, the documentation, the consortium arrangement, or the inspection and insurance covenants, then yes, the IBA standardised formats are very much in play, and those formats define the field you are auditing. Knowing which is which lets you set your scope correctly, rely on the right documents, and write a report that says precisely what you verified and nothing that you did not. For a special purpose assignment, that precision is the whole of the job.
