a) for a beneficiary considered alone, the amount shall be no less than the percentage of the minimum legal or minimum inter-occupational wage, or of the wage of an ordinary labourer, in respect of the contingency in question;
b) for a beneficiary with dependants, the said amount, increased by the amount of any family allowances paid during the period covered by the contingency, shall, in respect of the contingency in question, be no less than the percentage specified in the schedule of the sum of the minimum legal or minimum inter-occupational wage, or of the wage of an ordinary labourer, and the amount of any family allowances payable to a protected person with the same family responsibilities as the beneficiary.
2. The minimum wage, the wage of an ordinary labourer, the periodical payment and the family allowances shall be calculated on the same time basis.

a) either the gross wages before any tax or social security contributions, in which case the periodical payment to be compared with this wage is the gross periodical payment before tax or social security contributions; or
b) the wage net of any tax or social security contributions, in which case the periodical payment to be compared with this wage is the periodical payment net of any tax or social security contributions.
4. Where the legislation of a Party provides that the periodical payments are subject neither to tax nor to social security contributions, the minimum wage or the wages of an ordinary labourer to be taken into account for the purpose of this article may be the salary net of any tax or social security contributions.
