5(1)This paragraph applies where for any year this Part of this Schedule—
(a)applies to a van, or
(b)applies to each of two or more vans made available by the same employer.
(2)For the purposes of this paragraph a participating employee is an employee to whom—
(a)the van is available for his private use while it is a shared van (where only one van is involved),
(b)one of the vans is available for his private use while it is a shared van (where more than one van is involved), or
(c)some or all of the vans are available for his private use while they are shared vans (where more than one van is involved);
but an employee is not a participating employee unless he makes private use of the van, or (if more than one is involved) he makes private use of at least one of them, at least once while it is a shared van.
(3)In sub-paragraph (2) above—
(a)any reference to a van being available for an employee’s private use includes a reference to the van being available for the private use of others being members of his family or household, and
(b)any reference to an employee making private use of a van includes a reference to a member of his family or household making private use of it.
(4)This paragraph shall apply to each participating employee in the same way, irrespective of—
(a)the number available to a particular employee of the vans involved;
(b)the fact that a particular van involved is or is not available to him or used by him;
(c)the extent to which a particular van involved is available to him or used by him.
(5)Where this paragraph applies—
(a)find the basic value of the van for the year or (as the case may be) the basic value for the year of each van involved;
(b)take that basic value or (as the case may be) the aggregate of those basic values;
(c)find for each participating employee a portion of the figure taken under paragraph (b) above by dividing it equally among the participating employees.
(6)The figure found for a participating employee shall be taken to be the cash equivalent of the benefit to him in the year of—
(a)the van available to him while it is a shared van (where only one van is involved or only one of the vans involved is available to him), or
(b)the vans available to him while they are shared vans (where more than one van is involved and more than one of them is available to him).
