6.—(1) In its application to a multi-employer scheme, section 75 of the 1995 Act has effect in relation to each employer as if—
(a)the reference in section 75(2)(a) to a time which falls before any relevant event in relation to the employer which occurs while the scheme is being wound up were a reference to a time which falls before relevant events have occurred in relation to all the employers;
(b)the reference in section 75(2) to an amount equal to the difference being treated as a debt due from the employer were a reference to an amount equal to that employer's share of the difference being treated as a debt due from that employer;
(c)the references in section 75(3)(a)(i) and (b) to no relevant event of the kind there mentioned occurring in relation to the employer were references to no event of that kind occurring in relation to all the employers;
(d)the reference in section 75(4)(a) to a relevant event (“the current event”) occurring in relation to the employer were a reference to a relevant event or an employment-cessation event occurring only in relation to that employer;
(e)the reference in section 75(4) to an amount equal to the difference being treated as a debt due from the employer were––
(i)in a case where the difference is ascertained immediately before a relevant event occurs in relation to the employer, a reference to an amount equal to the employer's share of the difference being treated as a debt due from the employer; and
(ii)in a case where the difference is ascertained immediately before an employment cessation event occurs in relation to the employer, a reference to an amount equal to the sum of the cessation expenses attributable to the employer and the employer's share of the difference being treated as a debt due from the employer; and
(f)section 75(4)(d) and (e) were omitted.
(2) For the purposes of paragraph (1), an employer's share of the difference is—
(a)such proportion of the total difference as, in the opinion of the actuary after consultation with the trustees or managers, the amount of the scheme's liabilities attributable to employment with that employer bears to the total amount of the scheme's liabilities attributable to employment with the employers; or
(b)if the scheme provides for the total amount of that debt to be otherwise apportioned amongst the employers, the amount due from that employer under that provision.
(3) For the purposes of paragraph (2)—
(a)the total amount of the scheme's liabilities which are attributable to employment with the employers; and
(b)the amount of the liabilities attributable to employment with any one employer,
are such amounts as are determined, calculated and verified by the actuary in accordance with the guidance given in GN 19; and a determination under this paragraph must be certified by the actuary as being in accordance with that guidance.
(4) For the purposes of these Regulations an employment-cessation event occurs in relation to an employer if he ceases to be an employer employing persons in the description of employment to which the scheme relates at a time when at least one other person continues to employ such persons.
(5) For the purposes of paragraph (1), the cessation expenses attributable to an employer are all expenses which, in the opinion of the trustees or managers of the scheme, are likely to be incurred in connection with the employment-cessation event occurring in relation to the employer.
