Why financial reporting is regulated, and who it is regulated for

Published accounts are not a courtesy to shareholders and not a tax on honest companies. They exist because a buyer who cannot tell a good company from a bad one pays the price of an average one — and that single fact is enough to drive good companies out of the market altogether.

Explain the information asymmetry between a company and its investors, show numerically why it drives good companies out of the capital market, and say what disclosure, audit and board governance each contribute

Start with the problem, not the rulebook

Most students meet this topic as a list: companies must publish accounts, accounts must be audited, directors have duties, there is a governance code. The list is memorable and almost useless, because it answers the question "what are the rules?" and never the question an examiner actually asks, which is "what would go wrong without them?"

So begin somewhere else. Begin with a company that wants money and an investor who has money, and notice that only one of them knows what the business is worth.

The asymmetry, stated precisely

The people running a company know its order book, its bad debts, the lawsuit nobody has mentioned yet and whether this year's profit came from trading or from selling a building. The people being asked to fund it know none of that. This gap has a name in finance — information asymmetry — and it is not a moral failing on anyone's part. It is simply where the facts sit.

The gap matters because of what an investor does when faced with it. An investor who cannot verify a claim does not believe it and does not disbelieve it. They price the average. And pricing the average is what breaks the market.

The mechanism: averaging drives out the good

Suppose two companies look identical from outside and one is genuinely twice as valuable as the other. An investor who cannot tell them apart offers a price halfway between. Now look at what each company's owners do with that offer.

The owners of the good company are being offered less than their business is worth. They refuse, and keep it. The owners of the bad company are being offered more than theirs is worth. They accept at once.

So every seller who accepts is a bad company. Investors are not stupid; they work this out, and lower the price to what a bad company is worth. The good companies are now even further from a fair price. The market for good companies does not shrink — it closes.

This is the whole argument, and it is worth seeing it in numbers before trusting it. The worked example below does exactly that, and shows the price falling from a fair hundred to a fair fifty in two steps.

Notice what the mechanism does not depend on. Nobody lies. No accounts are falsified. Every party behaves rationally and in their own interest, and the outcome is still that good businesses cannot raise capital. That is why the response has to be a rule and not an appeal to honesty.

What disclosure actually buys

If the problem is that the two companies look alike, the fix is to make them look different. That is the job of a published, standardised, audited set of accounts: it lets the good company prove it is the good company.

Three words in that sentence are doing separate work, and students routinely collapse them into one.

Published

The information has to reach people who are not insiders. A fact known only to the board prices nothing.

Standardised

This is the one most often missed. If every company chose its own definition of profit, the numbers would be published and still incomparable, and the investor would be back to averaging. A common framework is not bureaucratic tidiness; comparability is the product.

Audited

A claim a company makes about itself and a claim an independent party will stake its licence on are not the same claim. The audit is what converts an assertion into evidence, and it is the reason the good company is willing to pay for one. The cost of the audit falls on the company that benefits from being distinguished.

Who the accounts are for, and why the answer is not "shareholders"

Shareholders are the most obvious users and not the only ones, and a question about users is marked on breadth. Each of these groups reads the same document for a different number.

Lenders and trade suppliers care about whether they will be paid, so they read cash, borrowings and the pattern of payment, not earnings per share.

Employees and their unions read the sustainability of the business and the capacity to pay.

Customers who are relying on a warranty or a long contract want to know the company will still be there.

Tax authorities and regulators read it against their own rules, which are not the same as the accounting rules.

Competitors read it too. This is the reason companies resist disclosure that goes beyond the minimum, and it is a legitimate cost of the system rather than evidence of something to hide.

Governance: the gap disclosure cannot close

Disclosure tells outsiders what happened. It does not stop the thing from happening. Between one annual report and the next, the people in charge of the company are not its owners — and their interests are not automatically the owners' interests.

That is the agency problem, and three of its forms are worth naming because each has a governance answer.

Effort. Managers bear the cost of working hard and share only part of the gain. Answer: pay linked to results.

Risk. A manager's job is undiversified while a shareholder's portfolio is not, so managers prefer the safe project even when the risky one is worth more. Answer: pay partly in equity, which pays off in the upside.

Horizon. A manager leaving in two years has no stake in year five. Answer: deferred and clawed-back pay.

Round the pay arrangements sits the structure: a board with directors who are not executives of the company, an audit committee that the auditor can speak to without management present, and a separation of the chair from the chief executive so that no one person both runs the company and leads the body that monitors it. Each of those exists to make it possible for someone to say no.

Questions students ask

If the market punishes bad companies, why not let it?

Because the mechanism above shows the market cannot identify them without the information. Punishment requires knowing who to punish, and that is precisely what is missing.

Why would a good company not just volunteer the information?

Many try, and run into two problems. An unaudited claim is cheap to make, so a bad company makes it too, and the signal is worthless. And a company publishing on its own chosen basis is still not comparable with the next one. Voluntary disclosure only separates companies when it is costly to imitate — which is the economic function of a statutory framework and an external audit.

Is this the same adverse selection as in insurance?

It is the same mechanism with the roles swapped. In insurance the buyer knows more than the seller, so the good risks withdraw from a pooled premium. In the capital market the seller of the shares knows more than the buyer, so the good companies withdraw from a pooled price. Both end with the better party leaving and the price falling. Recognising it twice is worth more than learning it twice.

A worked example

An invented example, built for this page. Two private companies in Pune, each wanting to sell the whole business, and an investor who requires a 20% return. Every figure is made up and chosen to keep the arithmetic exact.

  1. What each company is really worth

    Both will produce one lump of cash in a year's time and then be wound up.

    CompanyCash in one yearFair value today at 20%
    Alpha (the good one)₹120 lakh120 ÷ 1.20 = ₹100 lakh
    Beta (the weak one)₹60 lakh60 ÷ 1.20 = ₹50 lakh

    The owners know which company they own. The investor cannot tell, because nothing either company publishes would distinguish them.

  2. The investor prices the average

    Believing it is an even chance, the investor expects (120 + 60) ÷ 2 = ₹90 lakh of cash, and offers

    90 ÷ 1.20 = ₹75 lakh

    Now read that offer from each seller's side, using the printed values above.

    Alpha is worth ₹100 lakh and is offered ₹75 lakh. It loses ₹25 lakh by selling, so it withdraws.

    Beta is worth ₹50 lakh and is offered ₹75 lakh. It gains ₹25 lakh by selling, so it sells immediately.

    The two numbers are the same size, and that is the point: at the averaged price nothing has been created. ₹25 lakh has been moved from an investor to Beta's owners, and Alpha has been priced out.

  3. The price collapses

    Once Alpha withdraws, every company still for sale is a Beta. The investor who works this out will pay no more than

    60 ÷ 1.20 = ₹50 lakh

    which is exactly Beta's fair value. The market has not become smaller and fairer. It has become a market in weak companies only, at weak-company prices, and Alpha cannot raise money in it at any price it would accept.

  4. What an audit is worth to Alpha

    Suppose a credible audited set of accounts costs Alpha ₹2 lakh and lets the investor verify the ₹120 lakh. Alpha now sells at its own fair value of ₹100 lakh instead of the averaged ₹75 lakh, so

    gain = 100 − 75 − 2 = ₹23 lakh

    Check that a second way. The ₹25 lakh transfer identified in Step 1 is exactly what Alpha recovers by being distinguished, less the ₹2 lakh it spends doing so: 25 − 2 = ₹23 lakh. The two routes agree.

    And notice who will not pay for the audit. Beta gains nothing from being identified; being identified costs Beta ₹25 lakh. So the cost of disclosure is borne willingly by the company that benefits and resisted by the one that does not, which is why a voluntary system separates the two only when the disclosure is hard to fake — and why the statutory version exists at all.

  5. A sanity check on the whole example

    Total value in the two businesses is 100 + 50 = ₹150 lakh, and nothing in Steps 1 to 3 changed the cash either business will produce. All three steps only moved value between parties, or removed the chance to trade. That is the honest summary of an information problem: it does not make companies poorer, it stops the right owners from getting hold of them.
