Corporate Actions for NISM Research Analyst Exam

Corporate actions are decisions by a listed company that change its shares, capital structure or ownership, such as dividends, bonus issues, splits, rights issues, buybacks, mergers and delisting. To solve questions, identify the action, see what it does to share count and price, then apply the adjustment formula.

What this chapter covers

This chapter covers events a listed company undertakes that affect its shareholders and its share price. You will study dividends, bonus issues, stock splits, rights issues, buybacks, mergers, demergers, acquisitions, delisting and spin-offs. For each, you need to know what the action is, why a company does it, what it does to share count, price and ownership, and the key dates involved.

Most questions are of two kinds. The first tests definitions and distinctions, for example the difference between a bonus and a split, or between a record date and an ex-date. The second tests simple calculations, such as the price after a bonus or split, or the theoretical ex-rights price. Both are quick to score once the rules are clear.

The chapter connects to several other parts of the paper. Valuation Principles uses per-share data, which must be adjusted for bonus and splits. Company Analysis - Financial Analysis uses EPS and payout ratios, which change with these actions. Legal and Regulatory Environment covers SEBI rules that govern many of these events. Technical Analysis charts use adjusted prices. Learn this chapter well and those chapters become easier.

The chapter carries 5 marks in the revised NISM-Series-XV paper. That is modest, but the questions are largely rule-based and calculation-light, so they are among the easier marks to secure. With a 25% negative marking on wrong answers, clear rules help you avoid guesses. The concepts also feed into valuation and financial analysis questions, so time spent here pays back elsewhere in the paper.

Corporate Actions: topics in the order to study them

1Corporate Actions Overview and TypesStart here to see the full map of actions and the key vocabulary before studying each one.
2Dividends: Types, Dates and Price AdjustmentDividends are the most common action, and they teach the announcement, record date, ex-date and payment date sequence used by other actions.
3Bonus Issues and Stock SplitsThese change share count and price without changing value, and they build on the ex-date idea from dividends.
4Rights Issues and Theoretical Ex-Rights PriceRights bring a new calculation and need the share-count logic from bonus and splits first.
5Buyback of SharesBuybacks reverse issuance and are easier once you know how capital changes through bonus and rights.
6Mergers, Demergers and AcquisitionsThese restructuring actions are more conceptual, so study them after the share-level actions are settled.
7Delisting, Spin-offs and Other Corporate ActionsFinish with the remaining events, which are mostly definitions and are best revised last.

How to prepare Corporate Actions

Aim to understand what each action does to share count, price and shareholder wealth. Then practise the few calculations until they are automatic.

Read the overview topic and list every action with a one-line definition in your own words.
Learn the dividend date sequence in order: announcement, then the ex-date and record date, then the payment date. Note that the share price adjusts on the ex-date. Under T+1 settlement in India, the ex-date and the record date are normally the same day. You must buy before the ex-date, that is, by the day before it, to be on the register and eligible.
For bonus and split, write the ratio logic in words. For a 1:1 bonus (one free share for every one held), shares double and the price roughly halves. For a split of one share of ₹10 face value into five shares of ₹2 each, the share count rises five times and the face value falls to one-fifth.
For rights issues, practise the theoretical ex-rights price: (existing shares × market price + new shares × rights price) ÷ total shares after the issue. Do five numbers by hand.
Make a comparison table for buyback, merger, demerger, acquisition, spin-off and delisting: purpose, who is affected, and who approves.
Finish with timed MCQs on this chapter. For every wrong answer, note whether you misread the question, forgot a rule or made a calculation slip.

Common mistakes in Corporate Actions

Confusing bonus issues with stock splits
Fix: A bonus issue gives free shares by transferring reserves into paid-up share capital, and the face value stays unchanged. A split reduces face value and raises share count, while reserves and paid-up capital stay unchanged. Market capitalisation stays the same in both.
Mixing up the record date and the ex-date
Fix: The record date fixes who is on the register. The ex-date is when the stock trades without the entitlement. Under T+1 settlement in India, the ex-date and the record date are normally the same day. You must buy before the ex-date, that is, by the day before it, to be on the register and eligible.
Using the wrong share count in the ex-rights formula
Fix: Use the market price for old shares, the rights price for new shares, and total shares after the issue as the divisor.
Assuming a buyback always raises the share price
Fix: A buyback reduces share count and usually raises EPS. The price effect depends on the market, so avoid answers that say it always rises.
Forgetting to adjust past data after a bonus or split
Fix: Restate historical prices, EPS and dividends per share on the new share base before comparing.
Guessing on regulatory details such as approvals
Fix: Study these rules in the Legal and Regulatory chapter alongside this one, and skip the question if unsure, since wrong answers carry a penalty.

Last-day revision: Corporate Actions

A corporate action is a company decision that affects its shares, capital or ownership.
Dividend dates run in order: announcement, ex-date and record date (the same day under T+1), then payment date.
Buying on or after the ex-date does not entitle you to the dividend; you must buy before the ex-date.
Share price adjusts downward on the ex-date by roughly the dividend amount.
A bonus issue gives free shares from reserves; total value is unchanged, so the price falls.
A stock split reduces face value and raises share count; market capitalisation does not change.
After a bonus or split, adjust historical EPS and prices for comparison.
Rights issue offers existing shareholders new shares, usually at a discount, in proportion to holdings.
Theoretical ex-rights price = (old shares × market price + new shares × rights price) ÷ total shares.
A buyback reduces shares outstanding and usually raises EPS.
A merger combines companies; a demerger separates a business into a new entity.
Delisting removes shares from an exchange; check who approves and the exit offer to shareholders.

Corporate Actions: frequently asked questions

How many marks does Corporate Actions carry in NISM-Series-XV?

The revised paper allots 5 marks to this chapter. It is a small share, but the questions are mostly direct, so the marks are quite attainable.

Do I need to calculate in the Corporate Actions chapter?

Yes, but the calculations are simple. Expect adjustments for bonus and split, and the theoretical ex-rights price. Practise a few by hand and you will be fine.

What is the best way to learn the dividend dates?

Learn them as a sequence: announcement, then the ex-date and record date (the same day under T+1), then the payment date. Then ask what happens to a buyer on each day. This makes the ex-date rule easy to apply.

Is there negative marking for wrong answers?

Yes. NISM-Series-XV has negative marking of 25% of the marks assigned to a question. If you are unsure, eliminate options first and guess only when you can narrow it down.
