profits and losses for the period on the contract shall be computed on that basis for the purposes of this Chapter.
(2)Where subsection (1) above does not apply in the case of a qualifying contract held by a qualifying company and an accounting period, profits and losses for the period on the contract shall be computed for the purposes of this Chapter on a mark to market or accruals basis of accounting which—

(c)the method of valuation adopted is such as to secure the contract is brought into account at a fair value.

(a)computing the profits or losses on the contract on that basis is in accordance with normal accountancy practice;

(8)In the above definition of “reciprocal payment”, the second reference to a relevant payment includes a reference to any payment which—
(a)is subject to a condition precedent, and
