What Is a Stock Split or Share Reconstruction? What Changes on Your CSCS Statement

A stock split is a corporate action that divides each existing share into several new ones, so a shareholder ends up with more units at a lower price each. A share reconstruction, also called a consolidation or reverse split, does the opposite: several existing shares are combined into one, leaving fewer units at a higher price each. In both cases the company's total value and each shareholder's percentage of it are unchanged by the arithmetic. What changes is the number of units on your CSCS statement and the quoted price per unit.

The Arithmetic of a Split

Suppose a company announces a two-for-one split. Every shareholder receives two new shares for each one held. If you held 1,000 shares, you now hold 2,000. Because the company has not become any more valuable, the market price adjusts to roughly half of what it was, and the market value of your holding is the same immediately before and after the change. The same logic applies to a three-for-one or ten-for-one split; only the ratio differs.

Under the Companies and Allied Matters Act 2020, a company may subdivide its shares into shares of a smaller nominal amount, or consolidate them into shares of a larger nominal amount, with the approval of its shareholders and the appropriate filings at the Corporate Affairs Commission. For a listed company there are further steps with the Securities and Exchange Commission (SEC) and NGX, and the new shares are listed on the Exchange's daily official list in place of the old ones.

The Arithmetic of a Reconstruction

A share reconstruction runs the other way. In a four-for-one consolidation, every four existing shares become one new share. A holding of 1,000 shares becomes 250, and the market price adjusts to roughly four times its previous level. Reconstructions have been more common on NGX than splits in recent years, usually by companies whose share count had grown very large relative to the price at which the shares traded. The approvals follow the same pattern: a shareholders' resolution, no objection from SEC and, in some structures, an order of the court, after which NGX delists the old shares and lists the reconstructed ones.

When a reconstruction takes place, NGX usually places the shares on a short trading suspension around the effective date so that the register can be adjusted cleanly. The company's announcement gives the timetable.

What Changes on Your CSCS Statement

Nigerian listed shares are held electronically at the Central Securities Clearing System (CSCS) under your Clearing House Number (CHN). When a split or reconstruction becomes effective, CSCS adjusts the units in every affected account on the register as at the effective date. You do not need to submit any form or instruct your stockbroker; the adjustment is applied to all holders at once.

• Units: the quantity shown against the company changes by the ratio announced. After a two-for-one split, 500 units become 1,000; after a four-for-one consolidation, 1,000 units become 250.
• Price: the closing price used to value your holding changes in the opposite direction, so the market value column is approximately the same before and after.
• Fractions: a consolidation can leave fractional entitlements, for example 1,001 shares into four-for-one gives 250 shares and a fraction. The company's scheme document states how fractions are dealt with, which is commonly by rounding, by aggregating and selling them, or by paying the value in cash.
• Share certificates: if you still hold paper certificates rather than dematerialised shares, the company's registrar will explain how the old certificates are replaced. Dematerialised holdings are adjusted at CSCS without new paper.

Why Companies Do It

A company that splits its shares usually says it wants a lower price per unit so that smaller investors can buy round lots more easily. A company that consolidates usually says it wants to reduce a very large share count and lift a very low unit price. Neither action changes the company's assets, earnings or number of shareholders. Whether either has any lasting effect on how a share trades is a matter of opinion, and the company's stated reasons are set out in the circular sent to shareholders before the vote.

How It Differs From a Bonus Issue

A bonus issue also gives shareholders more shares for no payment, which is why the two are often confused. The difference is accounting. A bonus issue creates new shares by capitalising part of the company's reserves, so the issued share capital increases. A split simply divides the existing capital into more units of smaller nominal value, and the total nominal capital is unchanged. From an investor's point of view the effect on units and price per unit looks similar; the company's announcement will say which it is.

Splits and Reconstructions in Nigeria: FAQs

Do I have to do anything when a split or reconstruction is announced?

Usually not. Shareholders vote on the resolution at a general meeting, and once it is approved and effective the adjustment is applied to every account at CSCS automatically. Check your statement after the effective date to confirm the new unit count matches the announced ratio.

Will my contract notes still make sense?

Yes, but the unit counts and prices on old contract notes will be in pre-action terms. When reconciling, convert them by the ratio: 1,000 shares bought before a two-for-one split correspond to 2,000 units afterwards at half the price paid per unit. Keep the notes; the total amount you paid is unchanged.

What happens to a fraction of a share after a consolidation?

It depends on the scheme. The circular sent to shareholders sets out whether fractions are rounded, aggregated and sold with the proceeds paid out, or dealt with in another way. Your registrar can confirm how your own holding was treated.

Where is a split or reconstruction announced?

Listed companies file corporate action announcements with NGX, which publishes them on its website, and send a circular or notice of meeting to shareholders through the registrar. The announcement states the ratio, the record date and the effective date.
