(1)This section sets out the general rule for determining whether a person is treated as making accrued income profits or accrued income losses where securities are transferred by or to the person.
(2)This section does not apply in a case where section 630 applies.
(3)A separate calculation is to be made for each kind of security that is transferred by or to the person and for each interest period of each such kind of security.
(4)Each such calculation is to find—
(a)the total amount (“A”) of the payments treated under this Chapter as made to the person in the interest period in question in respect of transfers of securities of the particular kind, and
(b)the total amount (“B”) of the payments treated under this Chapter as made by the person in that period in respect of such transfers.
(5)A person is treated as making accrued income profits in an interest period as a result of transfers of securities of a particular kind if A exceeds B.
(6)A person is treated as making accrued income losses in an interest period as a result of transfers of securities of a particular kind if B exceeds A.
(7)For the payments that are treated as made on transfers of different kinds, see—
section 632 (payment on transfer with accrued interest),
section 633 (payment on transfer without accrued interest),
section 634 (payment on transfer with unrealised interest),
section 635 (payment on transfer of variable rate securities), and
section 637(2) (accrued income losses treated as payment on transfer in next interest period).
