(5) In this Part “fair value accounting” means a basis of accounting under which assets and liabilities are shown in the company's balance sheet at their fair value.

(6) In this Part “fair value”, in relation to a loan relationship of a company, means the amount which, at the time as at which the value is to be determined, is the amount which the company would obtain from or, as the case may be, would have to pay to a knowledgeable and willing person dealing at arm's length for—

(a) the transfer of all the company's rights under the relationship, and

(b) the release of all the company's liabilities under it.

(a) are required in accordance with generally accepted accounting practice to be dealt with for accounting purposes using fair value accounting, and
