(a)the amount of wages payable to the worker which consists of or includes an amount payable by way of contractual remuneration in respect of the last of the periods for which he is employed under his contract prior to its termination for any reason (but excluding any wages referable to any earlier such period), or
(b)where an amount in lieu of notice is paid to the worker later than the amount referred to in sub-paragraph (a), the amount so paid,
in each case whether the amount in question is paid before or after the termination of the worker's contract.

(3) Nothing in Article 52 or 53 applies to a payment falling within Article 52(1) which is made on or after the day on which any such worker's final instalment of wages is paid; but (even if the requirements of Article 47 would otherwise be satisfied with respect to it) his employer shall not be treated as receiving any such payment in accordance with that Article if the payment was first required to be made after the end of the period referred to in Article 52(3)(b).
(4) Article 53(3) does not apply to an amount which is to be paid by a worker on or after the day on which his final instalment of wages is paid.
