CFM62740 | Foreign exchange: matching under the Disregard Regulations: meaning of net asset value
From HM Revenue & Customs · Corporate Finance Manual
How net asset value matching works
Where a company holds shares in another company (referred to in the legislation as ‘company A’), and those shares are matched with a liability or derivative contract under condition 2 of regulation 3 or regulation 4, regulation 4A defines ‘net asset value’ in relation to those shares.
It is the value of the assets, less the value of the liabilities that are
owned by company A itself, or by a direct or indirect subsidiary of A, and
denominated in the relevant currency (see CFM62750).
‘Relevant currency’ means the currency giving rise to the foreign exchange risk referred to in regulation 3(3) and regulation 4(3) - the currency to which the company is exposed.
‘Subsidiary’ should be accorded the meaning that it has for accounting purposes, in other words a subsidiary of company A is any entity (including an unincorporated entity such as a partnership) that is controlled by A.
