This note is provided for the UK Atomic Energy Authority (UKAEA or the Authority) in its role as manager of the UK Atomic Energy Authority Pension Schemes ("the UKAEA Schemes").

The purpose of this note is to provide the Authority with factors to be used to convert the pension credit arising from a pension sharing order to a pension awarded to the ex-partner (or pension credit member). These tables should not be used to calculate cash equivalents on divorce.

The section titled Pension Credits on Divorce: General Considerations of this report covers general considerations, the section titled Guidance on Application of Pension Credit Factors describes the conversion calculation. The section titled HM Treasury Guidance on Divorce Calculations sets out HM Treasury guidance on transitional implementation issues for divorce cases.

The following changes have been made when reviewing this guidance:

• Important information around the expected audience for the guidance, use of the guidance, review of factors, compliance and limitations applies across all sets of guidance. Rather than being repeated in each set of guidance, this can now be found on the scheme home page. It is important to read this information alongside the guidance.
• Calculation methodology: No changes have been made to the calculation methodology.
• Examples: There are no examples in this guidance. Worked examples, using the calculation methodology, can be found in prior versions of the guidance (though please note that these use historic factors).
• Factor tables: The "Factor Tables" tab contains the names of the tables that are referenced in the calculation methodology. The tables of factors themselves can be found in the most recently published "Consolidated Factors Workbook" which is available by clicking the "Download current Consolidated Factors Workbook" button on the scheme's home page.
• Assumptions: The key assumptions underlying the factors in each note are contained in the Consolidated Factors Workbook.
• Regulations: The regulations that require the production of the actuarial factors and/or guidance that is the subject of this note are summarised in the "Regulations" tab.

The factors in this note should only be used to calculate the benefits for the ex-partner if the cash equivalent (and hence Pension Credit) has been calculated using consistent factors.

When calculating the pension awarded to ex-partner the administrator should first check whether any actions under the HM Treasury guidance are necessary.

We are unaware of any legal advice taken by the Authority in respect of backdating. The Government Actuary's Department (GAD) confirms that it has not taken any legal advice on this point in respect of the UK Atomic Energy Authority pension schemes. The Authority may wish to consider whether it should take legal advice to identify whether there remain any material issues in relation to its approach to backdating.

Any questions concerning the application of the guidance should, in the first instance, be referred to the Authority.

Cases where the member has taken partial retirement should be referred to GAD.
