2 Shares and securities

2.1 Gilt edged securities and Qualifying Corporate Bonds

These are exempt assets for individuals.

2.2 Disposal of shares - matching rules

Where shares are disposed of a problem arises in computing the allowable cost as shares in a company may have been acquired over several acquisitions at different costs and on different dates. Therefore HMRC have deemed that when shares in a company are disposed of, they are matched against acquisitions of shares in that company in the following order:

  • Shares acquired on the same day (as the sale)

  • Shares acquired within the 30 days following the sale (FIFO)

  • Shares from the share pool

A separate computation is done for each 'match'.

Note: The matching rules for individuals are different from those that apply to companies.

2.3 The share pool

This keeps a record of the following details of all shares acquired in a company:

  1. number of shares

  2. cost of shares - the number of shares will include all acquisitions including bonus issues and rights issues.

    • Bonus issues are where a company issues free shares to its existing shareholders on a proportionate basis to the number of shares already owned.

    • Rights Issues are where a company seeks to raise new share capital and offers its existing shareholders the right to acquire additional shares in the company, at an advantageous price, on a proportionate basis to the number of shares already owned .

  3. the shares disposed of from the share pool will be at the average cost of shares held in that pool.

The share pool is easier to produce for individuals than for companies, for as no indexation allowance applies the only information recorded is number of shares and cost of shares.

Jane owns shares in ABC Ltd. She acquired 1,500 shares in the company on 31 May 2020 for £20,000, and 500 shares on 30 June 2021 for £10,000. On 7 July 2025 Jane bought a further 200 shares in ABC Ltd for £4,000.

Jane sold 1,000 shares in ABC Ltd on 28 June 2025 for £25,000.

Calculate Jane’s capital gain on the disposal of the shares on 28 June 2025.

3 Bonus issues

Bonus shares: An issue of free shares to existing shareholders in proportion to their existing shareholding.

A bonus issue attaches to the shares that created the entitlement, which means that the share pool is increased by the number of shares acquired in the bonus issue but there is no increase in the cost.

Graham had the following transactions in Alderholt Ltd shares:

February 2021

Purchased 7,000 shares for £15,000

June 2021

Purchased 1,000 shares for £4,000

July 2021

Bonus issue of one for five

October 2025

4 Rights issue

Existing shareholders have the right to purchase new shares in proportion to their existing shareholding at a price which is usually below market value.

A rights issue attaches to the shares that created the entitlement, which means that the share pool is increased by the number and cost of shares acquired in the rights issue.

MCQ1:

Winifred gave 10,000 shares in Wills plc to her daughter during 2025/26. The shares were quoted on the Stock Exchange Official List at 120p-136p per share on the day of the sale.

Winifred had acquired 15,000 shares in Wills plc on 1st January 2019 for £4,000.

What is the chargeable gain on the gift of the shares?

Show answerHide answer

MCQ1: £10,133

Average price (120 + 136) /2 = 128p (£1.28)

£

Sales proceeds are therefore £1.28 x 10,000 shares

12,800

Less: cost (£4,000 x 10,000/15,000)

(2,667)

Capital gain

10,133

5 Exempt securities

Gilts and qualifying corporate bonds are exempt for individuals. Do not compute CGT merely because such an investment was sold at a profit. Company treatment is separate.

6 Quoted-share market value

Use the midpoint of the quoted bid and offer prices provided in the question: (lower quotation+upper quotation)/2. Multiply by the number of shares. FTX uses the given quotations; do not confuse the quotation per share with the value of the whole holding.

Noah gifts 100 quoted shares. The given quotations are £4.20–£4.60. Find deemed proceeds.

Show answerHide answer

Midpoint=(4.20+4.60)/2=£4.40. Value of 100 shares=£440. Use this market value for the gift disposal, then deduct the matched allowable cost.

Olga sells 600 shares for £3,600. She buys 100 shares on the same day for £500 and 200 shares ten days later for £1,100. Her existing pool holds 1,000 shares costing £4,000. Compute the gain and remaining pool.

Show answerHide answer

Match 100 same-day shares at £500; then 200 within 30 days at £1,100; remaining 300 from pool cost 300/1,000×4,000=£1,200. Total cost £2,800; gain £800. Remaining pool 700 shares/cost £2,800.

Pranav holds 1,000 pooled shares costing £4,000. A 1-for-4 bonus issue is followed by a 1-for-5 rights issue at £2 a share. Update the pool.

Show answerHide answer

Bonus adds 250 shares and no cost: 1,250 shares/£4,000. Rights issue adds 250 shares at £500 cost. Final pool 1,500 shares/cost £4,500; average cost £3 per share.
