Transitional adjustments relating to derivative contracts
121(1)If paragraph 120 applies in relation to a derivative contract of a company, then for each relevant accounting period a credit or debit of an amount equal to the transitional adjustment for the period must be brought into account for the purposes of Part 7 of CTA 2009 in the same way as a credit or debit which is brought into account in determining the company’s profit or loss for the period in accordance with generally accepted accounting practice.
(2)The relevant accounting periods are—
(a)the first accounting period of the company beginning on or after 1 January 2016, and
(b)each subsequent accounting period all or part of which falls within the transitional years.
(3)The transitional years are the 5 years beginning with the first day of the first accounting period of the company beginning on or after 1 January 2016.
(4)The transitional adjustment for each relevant accounting period is calculated as follows.
(5)Allocate a percentage of the overall transitional adjustment (determined under paragraph 120) to each of the 5 transitional years as follows—
| 1st year | 40% |
| 2nd year | 25% |
| 3rd year | 15% |
| 4th year | 10% |
| 5th year | 10% |
(6)If a transitional year coincides with an accounting period, the transitional adjustment for the accounting period is the amount allocated to that year.
(7)In any other case—
(a)apportion the amount allocated to each transitional year between accounting periods according to the number of days in the transitional year which fall within each period, and
(b)the transitional adjustment for an accounting period is the total of the amounts apportioned to that period.
