Fee Compression: Why the Margin Falls Faster Than the Fee
Fee compression is a sustained fall in the rate an asset manager charges on the value it holds. The cost line does not fall with it, so the operating margin falls faster than the rate does. At Vaidehi Asset Managers Limited, invented, a blended fee of 0.55 per cent of assets under management would leave nothing at all by the time it reached 0.33 per cent.
The rules on what may be taken out of a pooled arrangement, the base any such charge is struck on, whether a charge tied to an outcome may be taken at all and what a manager has to publish about its charges are settled by the Securities and Exchange Board of India (SEBI) at sebi.gov.in, and each of them moves. A printed figure would not merely go stale; it would be wrong from the morning it changed. The Association of Mutual Funds in India (AMFI) at amfiindia.com is the place to look up an industry total. The Institute of Chartered Accountants of India at icai.org governs when a fee earned across a year is recorded as revenue.
Here is the whole of the arithmetic in one line, before any of the reasoning. A price is being cut on a business whose costs were fixed before the cut. Revenue is a rate multiplied by a value, and only one of those two is falling, so anybody watching the product of them can miss the cut entirely. The profit is what is left after a cost line that did not move at all. So the profit moves more than either of the two numbers that made it.
One distinction carries the rest. A rate is a price and a revenue line is not, and fee compression hides in the distance between those two sentences.
What is actually falling when a fee is compressed?
The rate. Nothing else. Fee compression is a fall in the rate charged on the value held, and the everyday use of the phrase is loose enough that this needs saying plainly before anything is built on it. Compression is not a fall in revenue. Compression is not a fall in operating profit. And compression is not a fall in the rupee amount any one investor hands over in a year. An investor whose holding has grown can hand over more rupees at the lower rate than at the higher one.
Vaidehi Asset Managers Limited, invented for teaching, holds Rs 1,80,000 crore of assets under management and charges a blended feeOne rate that stands in for many. A blended fee is the weighted average of the rates charged across everything a manager runs, so no single arrangement is necessarily charged at it. of 0.55 per cent of assets under management across the year. The blended rate is the price of the service. Everything below is a consequence of it multiplied by something.
A rate that falls while the value it is charged on rises produces a revenue line that does not move at all, and the price of the service has still been cut. The claim sounds like a paradox and is arithmetic. The trap follows from it: the number a reader reaches for first is the one number that has been engineered, by nothing more sinister than multiplication, to say nothing about the thing they wanted to know.
A manager reports higher revenue this year than last, and the rate it charges on the value it holds went down over the same stretch. Has the price of its service gone up or down?
Why does the revenue line say nothing about it?
Because revenue is the rate multiplied by the value, and the value moves for reasons that have nothing whatever to do with the rate. Markets rise. Investors hand more money over. Both of those enlarge the number the rate is charged on, and neither of them is a decision the manager made about its price. So a falling rate can be hidden by a rising value, completely, and for years at a stretch.
Think of a stall that charges two rupees to fill a bottle of water. Trade doubles, and the owner cuts the price to one rupee fifty. The takings at the end of the day are higher than they have ever been, and the price of a bottle of water has fallen by a quarter. Nobody reading the takings alone would ever find that out. The takings are a product; the price is one of the two things multiplied to make it.
To see a fee falling, divide revenue by the value it was charged on and watch that quotientThe answer a division gives. A product is what two numbers make when multiplied together. A quotient is what one number becomes when divided by another. across periods. The quotient is the price and the product is not. The division is a single one, done from two lines of a published result, and it is the only reading here that a person with no access to anything private can perform.
A question worth settling first: a manager's fee rate falls by a tenth and nothing else changes at all. Does its operating margin fall by a tenth, by more than a tenth, or by less?
Why does the operating margin fall faster than the fee does?
The faster fall is an identity rather than a tendency, so it is worth proving rather than asserting. Operating profit is revenue less a cost line, and the cost line does not move when the rate moves. Research costs what it costs whether the rate charged is 0.55 per cent of assets under management or 0.33 per cent. So every rupee of revenue given up to a lower rate comes out of the operating profit whole, with nothing between the two to absorb any of it. The property has a name, operating leverageWhat a business has when its spending stays put while its takings move. Profit then swings by more than the takings did, whichever way they went., and it works in the direction nobody enjoys just as reliably as in the direction they do.
The percentage fall in the fee that wipes out the operating profit is exactly the operating margin. Read that twice. The two numbers involved sit on completely different bases and land on the same figure anyway. At Vaidehi Asset Managers Limited the margin is 40.0 per cent, struck on revenue. The fee falling from 0.55 per cent to 0.33 per cent of assets under management is a fall of 0.22 percentage points, and 0.22 over 0.55 is 40.0 per cent of the fee. One is a share of revenue and the other is a share of a rate, and they are the same number to the decimal.
Nothing about that depends on this manager. Write the cost line as any amount at all, write the fee as any rate at all, and the rate has to fall by exactly the share of revenue that the profit represents before the profit reaches nothing. The arithmetic is worth learning once rather than recomputing it nervously each time. The answer is already printed at the bottom of the manager's own results, sitting there as the operating margin.
Costs are Rs 594 crore for the year and assets under management are Rs 1,80,000 crore. At what blended fee does the operating profit reach nothing?
What is pushing the rate down, and can one manager stop any of it?
Five separate pressures show up again and again, and the useful exercise is not listing them but asking the same question of each one: is this something a single manager decided, and can a single manager undo it?
The first is scale. A larger manager spreads much the same cost line across a larger value, so it can charge less for the same work and still keep something. The second is money moving towards arrangements that cost less to run. The drift drags the weighted average rate down even if no single rate anywhere changes. The third is unbundlingCharging separately for work that used to be sold at one price. Two charges replace one, and the parts become comparable in a way the single price never was.: the work of choosing what to hold is separated from the work of advising a person what to do, so each gets paid for on its own. The fourth is disclosure. Disclosure makes charges comparable where they were once folded together, and a charge that can be compared behaves differently from one that cannot. The fifth is simply more places to buy from, so a person who dislikes a price can act on the dislike.
Not one of those five is inside any single manager's control, and the word structural in the phrase is doing exactly that work. The pressure is structuralDriven by the way a market is arranged rather than by what any one participant chose to do. A single participant can respond to it and cannot switch it off. rather than competitive: it is a property of how the market is arranged and not a move anybody made. A manager can respond to every one of them and cannot switch any of them off, and neither can all of them together.
Which of these forces pushing the rate down can a single manager stop: money moving towards arrangements that cost less to run, charges being disclosed and compared, or more places to buy from?
What can a manager do about a falling rate?
Four responses exist, and reading them as a list of four misses the point. Sort them instead by whose agreement each one needs before it can happen.
Gather more, so the same cost line sits on a larger value: that needs investors to decide to hand money over. Change the mix, offering more of what still carries a higher rate: that needs investors to decide to hold that instead. Change what is charged for, bringing in a charge on the outcome: that needs investors, and often somebody else again, to agree to a different arrangement. And spend less, needing nobody's agreement but the manager's own.
Three of the four responses are decisions somebody else has to make, and one of them is not. Sorting by whose agreement is needed beats sorting by cheap against expensive or fast against slow. The sorting shows which lever gets pulled when the pressure arrives. Under pressure, people reach for what they can move today. So does a business.
One question to settle before the control below. Costs stay at Rs 594 crore and assets under management stay at Rs 1,80,000 crore as the blended fee is dragged down towards 0.20 per cent. Where does the operating margin reach nothing?
One rate moving, one cost line refusing to move with it
The control opens at 0.55 per cent of assets under management and reproduces the worked reading exactly: revenue of Rs 990 crore, costs of Rs 594 crore, an operating profit of Rs 396 crore and an operating margin of 40.0 per cent of revenue. Drag the rate down and watch two things at once.
Educational illustration. Invented manager, invented figures, and no setting on this control is a statement about any charge anywhere. Two suppositions carry most of the weight here, and both are on show for that reason. The value held stays at Rs 1,80,000 crore wherever the control is put, when in real life a cheaper rate is often the very thing that pulls more value in. Spending stays at Rs 594 crore wherever the control is put. No business under this kind of pressure would really hold it there. One year throughout, and every rate on the control belongs to that year.
Where does a Performance Fee fit when the charge on size is squeezed?
A performance fee is a charge taken on the part of an outcome that sits above a stated reference, rather than on the size of the money held. A performance fee belongs in a treatment of compression for one reason, worth saying out loud rather than assuming: when the rate that can be charged on size is being squeezed, changing what is charged for is one of the four ways out, and a charge on the outcome is the response that changes who is paid regardless.
A charge struck on size is paid whatever happens to the money, and a charge struck on the part of an outcome above a stated reference is not. Only that fourth response changes who is paid regardless. Gathering more leaves the manager paid on size. Changing the mix leaves the manager paid on size. Spending less leaves the manager paid on size. Only the fourth alters the thing the charge is attached to.
The comparison of the two charges criterion by criterion is set out under performance fees. Whether a charge tied to an outcome may be taken for a given arrangement at all, what reference it would be measured against, and what stops the same rise being charged for twice are set by SEBI at sebi.gov.in.
Of the four responses to a falling rate on size, which one changes who is paid regardless?
Why is the cost line the only lever the manager controls outright?
Put the four standing questions of this business to a manager watching its rate fall, and the answers arrive in an order that explains the behaviour completely. Whose money is it? Somebody else's. Whose decision is it whether that money stays or leaves? Somebody else's again. Whose risk is it if the value falls? The person whose money it is. And who is paid regardless, at least where the charge is struck on size? The manager.
Now add the fourth question: whose decision is it what gets spent on people, on research and on systems? The manager's, entirely, immediately, and without asking anybody. The asymmetry is the whole reason the cost line is where the pressure lands. Every other response requires an investor to agree with something.
A manager under a falling rate reaches for the one lever it controls outright, and that lever is the people, the research and the systems the service is actually made of, so cutting it is never free. A cost line is not fat; it is the analysts who read the filings, the technology that keeps records straight, and the people who answer when something goes wrong. Cut it far enough and the thing being sold is a different thing. Whether any particular cut goes too far is not a question arithmetic can settle.
A manager facing a falling rate cuts its cost line hard. Name what the decision buys and what it costs at the same time.
What does the arithmetic look like at Vaidehi Asset Managers Limited?
Every figure below belongs to Vaidehi Asset Managers Limited, and every one of them is for a single year. The rate is moved and everything else is held. Holding the rest still is the only way to see the identity rather than take it on trust. Read the table across, and notice that the third column is the one the reader would never have predicted from the first.
| What is being read | At the starting rate | At the crossing point | At the far setting |
|---|---|---|---|
| The blended fee, per cent of assets under management | 0.55 | 0.33 | 0.20 |
| Assets under management, held at every setting | Rs 1,80,000 crore | Rs 1,80,000 crore | Rs 1,80,000 crore |
| Revenue for the year, being the rate on that value | Rs 990 crore | Rs 594 crore | Rs 360 crore |
| The cost line, held at every setting | Rs 594 crore | Rs 594 crore | Rs 594 crore |
| Operating profit for the year | Rs 396 crore | nothing | a loss of Rs 234 crore |
| Operating margin, per cent of revenue | 40.0 | 0.0 | minus 65.0 |
Work the crossing point out yourself and the mystery goes out of it. Take the cost line of Rs 594 crore and divide it by the Rs 1,80,000 crore it sits against, and 0.33 per cent of assets under management drops out. Charge exactly that rate and the year brings in Rs 594 crore, the cost line to the rupee, so nothing is left. The crossing point is a break-evenThe point at which revenue exactly meets costs and nothing is left over in either direction. A break-even is a level, not a target and not a forecast. expressed as a rate rather than as an amount, and expressing it that way is what makes it comparable with the fee.
The two numbers that matter most sit on different bases and are the same number: 0.22 over 0.55 is 40.0 per cent of the fee, and Rs 396 crore over Rs 990 crore is 40.0 per cent of revenue. The second is printed in the manager's own results. So the answer to how far the rate can fall before nothing is left was already published, in a different unit, by the manager itself.
Who outside the manager actually uses this, and how?
Somebody reading a manager's published results uses it in one division and one subtraction. Divide revenue by the value it was charged on in each period to get the price for that period, and set the two side by side. Then read the operating margin off the same results. The margin is also the distance the rate can fall before nothing is left, and the two readings together say how much room there is.
A person deciding where to hold their own money uses the mirror of it. The charge a manager takes is the amount somebody pays. And a lender to a manager uses the same margin as a measure of how much revenue can go before the interest stops being covered. All three readings come from two published lines and a division, and that is why the arithmetic is worth knowing rather than looking up. One caution belongs with it, and it is the same one the control above carries: the cost line does move in real life, so a straight reading of the margin as room to spare is a reading of an assumption, not of a fact.
The failure: reading a flat revenue line as a flat price
Vaidehi Asset Managers Limited reports revenue of Rs 990 crore for the year, and Rs 990 crore again for a later year. A reader records a business standing still and moves on to the next name on the list.
Underneath that unchanged line, two large things happened and cancelled. The blended fee fell from 0.55 per cent to 0.44 per cent of assets under management, a cut of one fifth in the price of the service. Assets under management rose from Rs 1,80,000 crore to Rs 2,25,000 crore, a rise of Rs 45,000 crore, being one quarter more value. The later pair multiplied together comes to Rs 990 crore, to the rupee. The revenue line reports neither the cut nor the growth. Revenue is the product of the two, and the product did not move.
Who makes this reading: anybody comparing a top lineThe revenue line of a set of results, so called because it sits at the top of them, above everything that gets taken away further down. across periods. Comparing top lines is the first comparison every summary makes, and the mistake is invisible in that comparison by construction rather than by carelessness. The cost of the mistake: a manager that has been repricingChanging the rate charged for a service that has not itself changed. The work is the same; only the price attached to it is different. its service downward for years looks stable right up until the value stops rising, and then the whole of the accumulated cut arrives at once, on a cost line that grew in the meantime.
The fix is one division, the same division the whole of this arithmetic points at: revenue divided by the value it was charged on, period by period, with the quotient watched rather than the product.
What does a falling fee not mean?
Three conclusions are waiting for a reader at this point, and none of the three follows.
A falling fee does not mean the service got worse. A price and a quality are different things, and nothing in the arithmetic above touches what is being delivered for the money. A falling fee does not mean the service got better either. The opposite mistake is just as common, and a lower price is not evidence of a better anything. And it does not mean any particular manager is in trouble. A manager whose value held rose faster than its rate fell has more revenue than it had before, not less, and its margin will have moved by the difference between those two movements rather than by either one.
The arithmetic shows what it shows and no more. The rules on what may be charged and the base any charge is struck on are set by SEBI at sebi.gov.in, and both move. Every rate above belongs to an invented business and was chosen to make a single identity visible.
The three rows settled elsewhere
| What is decided | Who decides it | The value |
|---|---|---|
| What may be taken out of a pooled arrangement, and which base a charge sits on | SEBI, sebi.gov.in | |
| Whether a charge tied to an outcome may be taken for a given arrangement at all | SEBI, sebi.gov.in | |
| What an asset manager has to publish about its charges, and how often | SEBI, sebi.gov.in |
Three rows, no values, and the reason is printed rather than implied. Each of the three is decided by the authority sitting inside its row, each moves when that authority moves it, and a figure typed into this table would be wrong from the day after it changed rather than merely dated. None of the arithmetic above depends on the three. A reader can carry this sheet to the source and fill it in during one sitting.
A manager's revenue is unchanged across two periods. What must it be divided by to find out whether the price of its service changed?
Where the arithmetic stops
The arithmetic above covers what happens to a manager's economics when the rate it charges on size falls, and it stops there. The comparison of a charge on size against a charge on an outcome, criterion by criterion, is set out under performance fees. Movements in assets under management between two dates are covered separately, as are the three lines of the arithmetic themselves. The share of their own holding a holder pays, the way that charge is taken out of the holding and the names the plans it is charged under go by are set out under the cost of holding a unit, where a different invented manager carries different figures, so no figure should be carried across to it. Which base a charge sits on, what may be taken out of a pooled arrangement, whether a charge tied to an outcome is permitted for a given arrangement, and what is disclosed about charges and how often all belong to SEBI at sebi.gov.in. The name and the site stand in place of every value.
