CFM55270 - Holders of convertible or share-linked securities: conversion of securities: example

Security converts into shares

In the example at CFM55260, Abacus converted a security into 10,000 ordinary shares in X plc. The transaction is one to which TCGA1992/S132 applies, so that no disposal of the 바카라 사이트˜old asset바카라 사이트™ (the convertible security) is deemed to take place, and instead the base cost of the 바카라 사이트˜new asset바카라 사이트™ (the shares) is identified with the cost of the 바카라 사이트˜old asset바카라 사이트™ (the convertible security). In that example, the cost was £1million.

However CTA09/S670(5) adjusts this £1m base cost of the shares for the purposes of a subsequent disposal. It is treated as increased (or reduced) by the total of:

  • the aggregate net chargeable gains (or allowable losses) already brought into account under CTA09/S641 (바카라 사이트˜G바카라 사이트™ and 바카라 사이트˜L바카라 사이트™), and
  • 바카라 사이트˜CV바카라 사이트™ (or for periods ending before 30 December 2006, the initial carrying value of the embedded option).

바카라 사이트˜CV바카라 사이트™ is the amount by which the carrying value of the host contract at the date on which the option is exercised exceeds the carrying value of that contract at the date on which the company became party to the security. The purpose of the 바카라 사이트˜CV바카라 사이트™ adjustment is to prevent double-counting between loan relationships and chargeable gains.

In the example:

  • aggregate chargeable gains of £50,000 have already been brought into account under S641, and
  • the carrying value of the host contract (the creditor loan relationship) when the option is exercised is £1 million; its carrying value when Abacus first subscribed for the security was £950,000; so 바카라 사이트˜CV바카라 사이트™ is £50,000.

These two amounts are added together. The result is a profit of £100,000. This is added to the base cost of the conversion shares. (A loss would be subtracted.)

Thus, in the example, the base cost of the conversion shares is £1,100,000 (the £1 million base cost under TCGA92/S132, plus £100,000). This reflects the fact that Abacus바카라 사이트™ economic profit of £100,000 from exercising the conversion option has already been taxed: £50,000 has been brought into account as loan relationship credits representing the accrual of the 바카라 사이트˜implied discount바카라 사이트™. The unindexed gain or loss on subsequent disposal of the shares is limited to the profit or loss arising after the option has been exercised - although, for indexation purposes, the normal TCGA rules apply and the shares will be treated as having been acquired on 1 January 2006.

Suppose that, instead of having subscribed for the convertible on 1 January 2006, Abacus bought it in the market on 1 January 2007 for £1,081,000, attributing £111,000 of the fair value to the embedded option and £970,000 to the loan relationship. When the option is exercised on 31 December 2008, the carrying values of the loan relationship and the embedded option are, again, £1 million and £100,000 respectively. In this case, an aggregate loss of £11,000 has been brought into account under S641, while the 바카라 사이트˜CV바카라 사이트™ amount is £30,000 (£1 million less £970,000). The aggregate of these amounts is a profit of £19,000. This is added to the amount treated as the base cost of the shares under TCGA92/S132 - £1,081,000 - to give a base cost of £1,100,000.

Thus the effect of these adjustments is always to exclude from the capital gains computation those amounts in respect of the convertible - including any exchange gains or losses, or impairment debits - that have already been taxed.
