Alteration of Share Capital: Consolidation, Subdivision and Redenomination

Updated 11 October 2026 · Fact-checked

Alteration of share capital means changing the structure of a company's shares without changing its total capital value, except for rounding. The main tools are consolidation, subdivision, redenomination and conversion. Check the articles, pass the right resolution, then notify the registrar. Do not confuse this with a reduction of capital.

Understand Alteration of Share Capital

A company's share capital is made up of shares, each with a nominal (par) value. Sometimes a company wants to change how that capital is divided. It may want fewer, larger shares or more, smaller shares. It may want to change the currency of the nominal value. It may want to change the form of its shares. These are alterations of share capital.

The key idea is that an alteration reorganises the capital. It does not return money to shareholders or cancel unpaid capital. So the total nominal value stays the same. That is why creditors are not given the special protection they get on a reduction of capital.

The main alterations are these:

Consolidation: combining shares into fewer shares of a larger nominal value. For example, ten shares of $1 become one share of $10.
Subdivision (or split): dividing shares into more shares of a smaller nominal value. One share of $10 becomes ten shares of $1.
Redenomination: changing the currency of the nominal value, for example from one currency to another, usually at an exchange rate set in the resolution.
Conversion: changing the form of shares, for example converting fully paid shares into stock, or converting one class into another where the constitution or the law allows it.

The details vary between legal systems, so for the Global variant focus on the principles. The power must be given by the law and the constitution. The decision is normally made by the shareholders by resolution. The registrar must be told. The rights attached to shares must not be altered by accident, so check whether class rights are affected.

Key formulas to remember

Total nominal value unchanged: Number of shares × nominal value (before) = Number of shares × nominal value (after); Use this to check any consolidation or subdivision. If the totals differ, you have made an error or it is a reduction or increase.
Consolidation: New shares = Old shares ÷ consolidation ratio; new nominal value = old nominal value × ratio; Fractions can arise if the number of shares is not divisible by the ratio. The company must deal with fractions, for example by selling them or rounding as the resolution provides.
Subdivision: New shares = Old shares × split ratio; new nominal value = old nominal value ÷ ratio; Rights attached to each new share must be proportionate. The proportion of paid-up to unpaid on each new share stays the same.
Redenomination: New nominal value = old nominal value × agreed exchange rate; Rounding can slightly change the total. Law commonly allows the rounding difference to be dealt with through a reserve.
Procedure rule: Check constitution → pass resolution → notify registrar; This is the usual sequence. Say that the power must exist in the law and not be barred by the constitution.

How to solve Alteration of Share Capital questions

Use this method for any scenario question on altering share capital.

1Identify the change: is the company combining shares, splitting them, changing currency, or changing the form of shares? Name it using the correct term.
2Check that it is an alteration and not a reduction. If money is returned or liability on unpaid shares is cancelled, it is a reduction and needs the stricter procedure.
3Do the arithmetic. Compute the new number of shares and new nominal value, then confirm that total nominal value is unchanged.
4Check authority: does the law give the power, and does the company's constitution allow or restrict it?
5State the approval needed: normally a shareholder resolution of the type the law requires, and check for class rights that may be affected.
6State the filing step: notify the registrar within the time the law sets, with the updated information on capital.
7Conclude clearly: say whether the alteration is valid and what the company must still do.

Quickest way: Three-check shortcut

When to use it: Use this for one- or two-mark objective questions where you must pick the correct statement or term.

Fewer, bigger shares means consolidation. More, smaller shares means subdivision.
Currency change means redenomination. Form change means conversion.
If the total nominal value stays the same, it is an alteration. If it falls or money goes back to members, it is a reduction.
Eliminate any option that says creditors must be consulted or the court must approve an ordinary consolidation or subdivision.

Common mistakes in Alteration of Share Capital

Treating subdivision and consolidation as the same thing
Both change the number of shares and the nominal value, so the names blur.
Fix: Link the word to the direction. Consolidation joins shares together into fewer. Subdivision divides them into more.
Saying total share capital changes after a split or consolidation
Students see the number of shares change and assume value changes.
Fix: Always multiply shares by nominal value before and after. The total should match.
Confusing alteration with reduction of capital
Both appear in the same chapter and both change share capital.
Fix: Ask whether capital is being returned or liability cancelled. If yes, it is a reduction with stronger safeguards. If no, it is an alteration.
Ignoring the constitution
Students focus on the law and forget that the articles may restrict or add requirements.
Fix: Always say that the power must come from the law and that the articles must not prohibit it.
Forgetting to notify the registrar
The shareholder vote feels like the end of the process.
Fix: Finish every answer with the filing step. The change is not complete in the public record until the registrar is told.
Overlooking fractions after consolidation
Students do the division and do not check that it works out exactly.
Fix: If the share count is not divisible by the ratio, note that fractional entitlements arise and the company must provide how they are handled.

Worked examples

Example 1

Delta Ltd has 600,000 issued shares of $0.50 each, fully paid. The members resolve to consolidate them into shares of $5 each. Calculate the number of new shares and state whether the total nominal value changes.

Show the solution

Total nominal value before = 600,000 × $0.50 = $300,000.
Consolidation ratio = $5 ÷ $0.50 = 10 old shares for each new share.
New number of shares = 600,000 ÷ 10 = 60,000.
Total nominal value after = 60,000 × $5 = $300,000.
The totals match, so this is an alteration and not a reduction.

Answer: There will be 60,000 shares of $5 each. Total nominal value stays at $300,000. The company must follow the required resolution and notify the registrar.

Example 2

Kopa Ltd has 40,000 shares of $10 each, fully paid. The directors want to split each share into five shares. (a) State the nominal value and number of shares after the change. (b) Explain what approval and filing are needed.

Show the solution

(a) Number of new shares = 40,000 × 5 = 200,000.
New nominal value = $10 ÷ 5 = $2.
Check: 200,000 × $2 = $400,000, which equals 40,000 × $10 = $400,000.
(b) The change is a subdivision, an alteration of share capital. Check that the articles do not bar it.
The members normally approve it by the resolution the law requires, since the directors alone cannot do it. Check whether any class rights are affected.
After approval, the company notifies the registrar of the change.

Answer: After subdivision there are 200,000 shares of $2 each, with total nominal value unchanged at $400,000. The members must approve by resolution, the articles must permit it, and the registrar must be notified.

Exam tips

Write the arithmetic check: shares × nominal value before and after. It earns marks and catches slips.
In Section B multi-task questions, name the exact term first (consolidation, subdivision, redenomination or conversion), then apply it.
If a question mentions returning money to shareholders or cancelling unpaid capital, switch to reduction of capital and its creditor protections.
Learn the sequence of constitution, resolution and notification so you can close any procedure answer in one sentence.
Read the answer options for traps such as swapped definitions of consolidation and subdivision.

Alteration of Share Capital: frequently asked questions

What is the difference between consolidation and subdivision of shares?

Consolidation combines shares into fewer shares with a higher nominal value. Subdivision splits shares into more shares with a lower nominal value. In both cases the total nominal value stays the same.

Is alteration of share capital the same as reduction of share capital?

No. An alteration reorganises the shares without returning capital to members or cancelling liability on unpaid shares. A reduction lowers the capital and has stricter procedures to protect creditors.

What is redenomination of share capital?

It is changing the currency in which the nominal value of shares is expressed. The new nominal value is worked out using an exchange rate set out in the resolution. Rounding differences may arise and the law usually says how to treat them.

Who approves an alteration of share capital?

Normally the shareholders approve it by resolution, provided the law gives the power and the constitution does not prohibit it. The company then notifies the registrar. Check the rules of the legal system given in the question.
