Computing the taxable amount: examples
Example 1: securities acquired on or after 1 September 2003
100 Convertible shares were acquired by A Smith on 1 December 2003 and were converted into 100 Ordinary shares on 31 March 2004. On acquisition, Smith paid 50p for each share which at that time were worth £1 on a non convertible basis and £1.25 on a convertible basis.
There was no consideration given for the right to convert the securities as the non-convertible market value on acquisition exceeded the price paid by Smith (see ERSM40070).
To calculate the tax charge on acquisition; reduce the non-convertible market value by the amount paid for the shares, so:
Taxable amount on acquisition = (100 x £1) less (100 x .50p) = £50.
Smith paid £25 to convert the securities on 31 March 2004 when the Ordinary shares acquired were worth £3 each and the original Convertible shares were worth £2 each (on a non-convertible basis). There were no other expenses incurred by Smith for the conversion and no
To calculate the tax charge on conversion; apply the formula
CMVCS – (CMVERS + CC)
CMVCS: Market value of newly converted securities = 100 x £3 = £300
CMVERS: Market value (non convertible basis) of original securities when converted
= 100 x £2 = £200
CC: Consideration given to convert the securities = £25
Taxable amount on conversion = 300 – (200 + 25) = £75
Example 2: securities acquired before 1 September 2003
Claire Brown paid tax on convertible loan stock acquired from her employer on 1September 2002. This included a charge on the value of ‘right to convert’. She received £100 convertible loan stock @ 10% with a right to convert into shares in three years’ time. A payment of £10 is required to convert. The total market value on acquisition was £120, on which she paid tax. The value of the right to convert was agreed at £20. After three years the stock, ignoring the right to convert, is now worth £200 (because interest rates have declined), and the shares into which the stock is converted are worth £300.
From the consideration received (cash on sale, or market value of new securities onconversion) will be deducted
the current value of the old security ignoring the right to convert,
anything paid for conversion, and
part of the old convertible security’s value (paid for or charged to tax) that related to the acquisition of the right to convert.
This will allowed as a deduction in the s 440(1) ITEPA formula, per subsection (3). The computation will be, using acronyms in s440 and s441 ITEPA.
CMVCS – (CMVERS + CC) – CE
where:
CMVCS is Current Market Value of Converted Securities,
CMVERS is Current Market Value of Employment Related Securities,
CC is Consideration for Conversion, and
CE is Consideration for Entitlement to convert plus expenses.
Thus:
Taxable amount on conversion = 300 – (200 + 10) – 20 = £70
