OT30210 | Capital Gains: Rebasing of Assets Held at 31 March 1982 - Revoking an election for universal rebasing
From HM Revenue & Customs · Oil Taxation Manual
Following the change in the legislation (see OT30205), an election made before 22 January 1990 may have become potentially disadvantageous to an oil company (or group). A company was therefore given the right to revoke the election in writing before 1 January 1991.
