Credit Cost vs Provision Cost: The Flow and the Stock

A loan that goes wrong costs a lender money once, and then shows up in its accounts several times, on dates decided by a rule rather than by anything that happened. Every difference between the two figures in the title comes out of that one gap. The money is gone at one moment. The accounts say so at another. And the two words most often used for the consequence get treated as synonyms by readers who have never had cause to separate them.

Here is the everyday shape of it, before any lender appears. A household puts something aside every month against a roof that will need redoing. The household put aside twelve thousand rupees this year. The tin has been filling for years, so it now holds fifty thousand rupees. The amount set aside this year is Rs 12,000/-; the amount already ready is Rs 50,000/-, and neither answer gives the other one. A charge for a year and an amount held at a date are two different quantities that happen to be measured in the same unit. Everything below is that sentence, applied to lending.

What does credit cost measure, and over what period?

Credit cost is the charge a lender takes for a period because some of its lending did not come back in full. Credit cost is reported as a rupee amount and read as a rate. The rate means nothing until the book it sits on and the length of the period it covers are both named. A credit cost with no base and no period is not a rate at all, it is a rupee amount wearing the clothes of one. That sounds pedantic until two lenders have to be compared and the comparison will not go through.

Rukmini Finance Limited charged Rs 396 crore of credit costs in its stated year. Divide that by assets under management of Rs 18,000 crore and the answer is 2.20 per cent, for one year, on assets under management. Every clause in that sentence is load bearing. Move the base and the same Rs 396 crore reads as a different number about a different thing.

Look at the two readings printed in the dark band. Nothing about the lending changed between them. Rs 396 crore is a small slice of Rs 18,000 crore of book and almost half of Rs 846 crore of profit, and both statements are true at the same time about the same rupees. The base is not a formatting choice, it is most of the meaning. That point returns twice more below.

What does provision cost measure, and over what period?

A provision is an amount taken out of one year's profit against advances the lender does not expect to recover in full. The provision cost, or the provision charge, is the total of those amounts for the period. The charge reduces profit in the year it is made whether or not a single rupee has moved anywhere. A provision is therefore a recognition rather than an event.

Two things a provision is not, and both catch people. A provision is not money set aside in a box, and a provision is not a decision that the lending is gone. Nothing is transferred anywhere and nothing is locked away. The carrying value of the book comes down, the profit for the year comes down with it, and the lender goes on trying to collect exactly as before. Suvarna Commercial Bank Limited charged Rs 1,800 crore of provisions in its stated year. On gross advances of Rs 1,44,000 crore that charge is 1.25 per cent.

Notice that both lenders now have a charge sitting between an operating profit and a profit before tax, and that both charges read small against the book and large against the profit. The pattern is not a coincidence and not a quirk of these two sets of accounts. A lending charge is a small fraction of a large book landing on a much smaller profit. A change in the charge therefore moves earnings far more than it moves the balance sheet.

Which question is each of the two figures actually answering?

Both sides are now defined, so they can be put next to each other. Credit cost answers what this year of lending cost me. Provision cost answers what I charged against profit this year. The two questions are different, and a reader who treats them as one has merged an outcome with a recognition. In many years the two produce very similar rupee amounts, which is precisely why the merge goes unnoticed for so long.

The distinction survives even where the amounts agree exactly. If a lender's credit cost for the year and its provision charge for the year were both Rs 1,000 crore, that would be an agreement about a quantity and not an agreement about a meaning. One number would be describing lending that did not come back. The other would be describing an entry that a rule placed in this year rather than the last one or the next one. Two numbers can match to the last rupee and still be answers to unrelated questions. So the terms on which two figures agree have to be established before the agreement carries any weight.

What is the difference between a charge for a year and an amount held?

One more separation sits inside provisioning itself, between a charge for a year and an amount held at a date. The charge is a flow: it passes through one year's profit and loss and then it is gone from that statement forever. The provisions held are a stock: they sit against the book at a single date, and they got there because several years of flows went through before this one. Suvarna Commercial Bank Limited holds Rs 4,536 crore of provisions against a charge of Rs 1,800 crore for the year, so the stock stands at 2.52 times the flow.

The division that matters is the stock over the flow. Rs 4,536 crore over Rs 1,800 crore is 2.52 times. The protection already standing against the book is more than two and a half years of the current year's charge. The charge read on its own would suggest something in the region of one year. The whole gap between reading a flow and reading a stock sits in that difference, and it is why one year's charge can never say how much protection is already standing.

The stock has a structure inside it, and that structure is where the denominators start moving. Non-performing advancesAdvances a lender has stopped treating as performing. The authority named below decides precisely where that line sits. at Suvarna Commercial Bank Limited are Rs 6,480 crore gross, which is 4.50 per cent on gross advances of Rs 1,44,000 crore. Its provision coverageHow much of what has already gone wrong is already covered. Provision coverage describes a position on one date rather than anything that happened across a year. is 70.0 per cent, so Rs 4,536 crore is held. Rs 6,480 crore less Rs 4,536 crore leaves Rs 1,944 crore, and that remainder sits against net advancesWhat survives of the lending book once the provisions standing against it come off. Smaller than the gross figure by precisely that amount, never by more and never by less. of Rs 1,44,000 crore less Rs 4,536 crore, which is Rs 1,39,464 crore, giving 1.39 per cent on net advances.

Why do the two clocks start at different moments?

There are two clocks running over any advance that goes wrong, and they were never meant to agree. The economic clock runs when the money stops coming back and when the lender's view of what will eventually come back changes. The accounting clock runs when a recognition rule says a charge falls into a period. The two clocks are deliberately different, and the gap between them is the entire reason a lender can look worse in a year when nothing new went wrong and better in a year when something did.

Why would anybody build it that way on purpose? Because the economic clock has no fixed hands. Nobody can say to the rupee, on any particular morning, what a book of advances will finally return. If every lender were left to place its charges on its own reading of that, no two sets of accounts would be comparable and a lender under pressure would place them wherever it suited. So the accounting clock exists to fix when the entry falls, in advance and in the same way for everybody. The accounting clock buys comparability at the cost of timing, and the timing is what confuses a reader.

Two authorities decide where the marks on the lower line fall. When an advance stops being treated as performing, and what is provided against it at each stage it passes through, belong to the Reserve Bank of India at rbi.org.in. When a financial asset is recognised, measured and impaired in a set of accounts belongs to the Institute of Chartered Accountants of India at icai.org. Both sets of requirements move. A requirement written out in full would be wrong rather than merely out of date on the morning it changed, and wrong is much harder to notice.

Which base does each rate belong on, and what breaks when they are swapped?

Now the base test, run on both figures side by side rather than taken on trust. Rukmini Finance Limited's Rs 396 crore is 2.20 per cent of assets under management of Rs 18,000 crore. Suvarna Commercial Bank Limited's Rs 1,800 crore is 1.25 per cent of gross advances of Rs 1,44,000 crore. The very same Rs 1,800 crore over earning assetsEverything on a lender's books that actually earns interest, which is a wider collection than the lending alone. A rate struck across it comes out lower for exactly that reason. of Rs 2,04,000 crore reads 0.88 per cent.

Put the two lenders on one axis and the danger becomes obvious. 2.20 per cent is 1.76 times 1.25 per cent. The two bases are not the same base, so the comparison is worth making only when the sentence says which book each rate sits on. The distance along the axis below is a real distance between two rates. Two rates that far apart on two different books are still two rates, never two lenders.

What does the whole build look like set out in one table?

Every figure used above appears below, in the order it was worked, with the division printed rather than the answer alone. Two lenders sit in it, and one of them has no stock figure anywhere in this record. A stock that was never reported cannot be reconstructed out of a single year's charge.

Two subtractions hold the whole table together and both are worth doing on paper. Rs 6,480 crore less Rs 4,536 crore is Rs 1,944 crore, the uncovered part. Rs 1,44,000 crore less Rs 4,536 crore is Rs 1,39,464 crore, the book those uncovered advances are measured against. The same Rs 4,536 crore comes off the top and off the bottom, and forgetting the second one is the commonest arithmetic slip on this whole subject.

Three things are worth taking away from that panel. The block of gross non-performing advances never changes size, so no amount of coverage removes a single rupee of lending that went wrong. The provisions come off the top and off the bottom together. The ratio therefore does not fall in proportion to the coverage. And the shortcut reading is always low by exactly the same factor: Rs 1,44,000 crore over Rs 1,39,464 crore is 1.0325 times, so at the opening setting 1.35 per cent has to be lifted by 3.25 per cent of itself to reach the 1.39 per cent that the division actually gives.

Which of the two figures is a choice, and which is an outcome?

Reading a difference in charge as an accusation is the easiest mistake left on this subject. The stock a lender holds is settled partly by a rule and partly by the lender's own judgement about what it will eventually recover. The coverage figure of 70.0 per cent at Suvarna Commercial Bank Limited is that lender's own reported figure and nothing else. Two lenders with identical books can report different charges in the same year, and neither of them is wrong.

The interesting part is what does not follow. Neither charge says the lender behind it is being generous or careless, and no such verdict can be drawn out of a single reported figure. A difference in charge between two lenders is a thing to name and go and ask about. A difference is not a thing to rank. The honest sentence is that the two lenders have made different judgements inside a rule that permits a range, and that the range exists because nobody can know the answer in advance.

How does somebody reading two sets of accounts actually use this pair?

An analyst covering lenders does not read the charge and the stock as two facts. An analyst reads the charge and the stock as a pair, and the pair asks one question: is this year's charge topping up protection that was already thin, or adding to protection that was already deep? At Suvarna Commercial Bank Limited the answer is legible in one division. Rs 4,536 crore of stock against Rs 1,800 crore of flow is 2.52 times, so this year's charge landed on top of something substantial.

A lender's own credit team uses the pair differently again, and closer to home. Consider a vegetable seller who throws away what has spoiled. The vegetables she threw away this week are a flow. The crate she has already set aside because she thinks it will not sell is a stock. If she wants to know whether this was a bad week she looks at the first. If she wants to know how much cushion she has before a bad week actually hurts, she looks at the second. Neither number answers the other question. She can see both at once, so she would never confuse them. In a set of accounts the two are printed a long way apart.

And somebody putting money into a lender uses the pair as a warning system rather than a score. A charge rising while the stock stays flat and a charge rising while the stock climbs are two completely different stories, and the charge alone cannot tell them apart. That is the practical reason to insist on both numbers, and it costs one division to check.

What does neither of the two numbers say?

Most misreadings of a lender's accounts begin in the gaps rather than in the definitions. What matters is not that these things are missing, but that each absence can be given a shape. An absence with a stated bound is a finding; an absence quietly filled with a plausible number is a fault that nobody downstream can detect. So each row below says what is missing and what kind of limit can honestly be put on it.

One more absence deserves saying plainly rather than putting in a table. Neither figure says anything at all about the people who borrowed, and that is not a gap in the accounts. The silence is a fact about what accounts are for. A set of accounts records what a lender charged and what a lender holds. Nothing in a credit cost or a provision charge is a statement about anybody's character, and a reader who treats it as one has read a lender's arithmetic as a verdict on somebody else.

Where do the five blank rows get filled in?

Two authorities settle every requirement named above. Each row names one of them, the site where its current text lives, and the day it was last opened. An address outlives a value, and an address is worth more than a copied number.
