Where the accrued benefits consist in a refund of contributions, the value of those benefits corresponds to the contributions paid with interest calculated in accordance with the Act respecting the Government and Public Employees Retirement Plan (chapter R-10) and at the rates in Schedule VI to that Act until 31 May 2009 and at the rates in Schedule II to the Régime de retraite des membres de la Sûreté du Québec as of 1 June 2009. The interest is accrued to the date of assessment, as though the refund was made at that date. The same applies in respect of the value of the benefits accrued for the period of the marriage or civil union.
