  "text": "(This note is not part of the Order)\nThis Order specifies the conditions that a project carried out in an oil field must satisfy in order for that oil field to be an “additionally-developed oil field” (“ADOF”) for the purposes of Chapter 7 of Part 8 of the Corporation Tax Act 2010 (c. 4) (“CTA 2010”). An oil field that is an ADOF qualifies for a “field allowance”. The effect of a field allowance is to reduce the extent to which profits are subject to the supplementary charge. In addition, this Order inserts a new section 356A into the CTA 2010. This new section prescribes the method by which the total field allowance for an ADOF is to be calculated. This Order also makes a number of consequential amendments to Chapter 7 of Part 8 of, and Schedule 4 to, the CTA 2010; firstly, to specify the time at which a company having an interest in an ADOF is entitled to the field allowance, and secondly, to amend section 349A(1) of the CTA 2010 so that the language of that provision more accurately reflects the way in which approval for the carrying out of projects is granted.\nThe effect of this Order, read with section 337 of CTA 2010, is that companies will be able to hold a field allowance from the beginning of any accounting period in which an authorisation day that falls on or after 7th September 2012 falls. Companies will be able to activate a field allowance for any accounting period beginning on or after the first day of the first year of expected first production; where the year of expected first production is 2013, companies will be able to activate a field allowance for any accounting period beginning on or after 1st January 2013 and ending on or after 1st April 2013. Authority for this limited retrospective effect is given by section 349(3)(b) of the CTA 2010.\nArticle 2 specifies five conditions that a project carried out in an oil field must satisfy in order for that field to be an ADOF.\nArticles 3 to 12 amend Chapter 7 of Part 8 of and Schedule 4 to CTA 2010; articles 3 to 9 and 11 to 12 make the consequential changes referred to above.\nArticle 10 inserts a new section 356A into the CTA 2010. In summary, this section provides that an ADOF receives an amount of field allowance, up to a specified maximum, based upon the amount of capital expenditure which it is expected will be required to win a quantity of oil measured in tonnes.\nA Tax Information and Impact Note covering this instrument was published on 23rd October 2012 and is available on the HMRC website at http://www.hmrc.gov.uk/thelibrary/tiins.htm. It remains an accurate summary of the impacts that result from this instrument.",
