Share Capital and Share Classes

A guide to share capital and share classes in UK companies, covering nominal value, issued capital, share premiums, different classes of shares and how share capital appears in the accounts.

Share capital is the total amount of money a company raises by issuing shares to its shareholders. It represents the permanent investment in the company and forms part of the company’s equity on the balance sheet. Every UK private limited company must have at least one share when it is incorporated.

Key Terminology

Term Definition
Authorised share capital The maximum share capital the company can issue (abolished for companies formed after 1 October 2009, but older companies may still have this in their articles)
Issued share capital The total nominal value of shares actually issued to shareholders
Paid-up share capital The amount shareholders have actually paid for their shares
Unpaid share capital The portion of issued capital not yet paid by shareholders
Nominal value (par value) The face value of each share as stated in the company’s constitution
Share premium The amount paid above the nominal value when shares are issued

Nominal Value

Every share must have a nominal value (also called par value). This is the minimum price at which the share can be issued and is set when the company is incorporated. Common nominal values are £1, £0.01 (1p) or £0.10 (10p).

The nominal value does not reflect the market value of the share. A share with a nominal value of £1 could be worth significantly more (or less) depending on the company’s performance.

Example

A company issues 1,000 shares with a nominal value of £1 each:

Component Amount
Issued share capital £1,000 (1,000 × £1)
Paid-up share capital £1,000 (assuming fully paid)

Share Premium

When shares are issued at a price above their nominal value, the difference is recorded as a share premium. The share premium account is a non-distributable reserve — it cannot be used to pay dividends.

Example

A company issues 500 shares with a nominal value of £1 each at a price of £5 per share:

Component Calculation Amount
Total raised 500 × £5 £2,500
Share capital 500 × £1 £500
Share premium 500 × (£5 − £1) £2,000

Types of Share Classes

Companies can create different classes of shares with different rights. The most common classes are:

Ordinary Shares

The standard class of shares, carrying:

Most private limited companies have a single class of ordinary shares.

Preference Shares

Shares with preferential rights, typically including:

Preference shares can be cumulative (unpaid dividends accumulate) or non-cumulative (unpaid dividends are lost).

Alphabet Shares

Different classes of ordinary shares (A shares, B shares, C shares, etc.) with varied rights. Alphabet shares are commonly used in family or owner-managed companies to:

Redeemable Shares

Shares that the company can buy back at a future date at a predetermined price. The company must have non-redeemable shares in issue at all times.

Non-Voting Shares

Shares that carry no voting rights but may have full dividend and capital rights. Often used for employee share schemes or passive investors.

Creating Share Classes

Share classes are defined in the company’s articles of association. To create a new class of shares, the company must:

  1. Pass a special resolution (75% majority) to amend the articles
  2. File the amended articles and the resolution with Companies House
  3. Update the statement of capital to reflect the new class
  4. Update the statutory books

Issuing New Shares (Allotment)

When a company issues new shares, the directors must have authority to allot shares. For private companies with one class of shares, the directors have automatic authority under s.550 Companies Act 2006.

For companies with multiple share classes, the directors need authority from the shareholders (by ordinary resolution under s.551).

Pre-Emption Rights

Existing shareholders generally have a right of first refusal when new shares are issued (s.561). This means new shares must be offered to existing shareholders in proportion to their current holdings before being offered to anyone else.

Pre-emption rights can be disapplied by a special resolution (75% majority).

Steps to Issue Shares

  1. Check directors have authority to allot
  2. Offer shares to existing shareholders under pre-emption rights (or disapply)
  3. Pass a board resolution to allot the shares
  4. Issue share certificates within 2 months
  5. File a return of allotment (form SH01) with Companies House within 1 month
  6. Update the register of members and statement of capital

Share Capital in the Accounts

Share capital appears in the equity section of the balance sheet:

Equity Component Description
Called up share capital Nominal value of all issued shares
Share premium account Amounts paid above nominal value
Retained earnings Accumulated profits less dividends paid
Other reserves Revaluation reserve, capital redemption reserve
Total equity Sum of all components

Accounting Entries for Share Issue

Transaction Debit Credit
Shares issued at nominal value Bank Share capital
Share premium element Bank Share premium account

Share capital and share premium are non-distributable — they cannot be returned to shareholders as dividends. They can only be reduced by following the formal capital reduction procedures under the Companies Act 2006.

Statement of Capital

Every time shares are issued or the share structure changes, the company must file an updated statement of capital with Companies House. The statement shows:

The statement of capital is also confirmed as part of the annual confirmation statement.

Minimum Share Capital

Company Type Minimum
Private limited company (Ltd) £1 (one share of at least 1p)
Public limited company (PLC) £50,000 (at least 25% paid up)
