"Figure 8.4: Distribution of active membership of private sector occupational pension schemes: by type of scheme and employer contribution rate, 2009 to 2013","" "United Kingdom, percentages","" "","" "Notes","1. Excludes schemes with fewer than 12 members 2. Excludes non-contributory arrangements and contributions paid as fixed amounts only 3. Percentages are calculated excluding non-response 4. In 2010, the OPSS questionnaire was redeveloped to ensure that, if there were different contribution rates for different groups of members, then these were recorded. The scheme was asked to give the different rates and the corresponding proportion of active members to whom that rate applied. Prior to 2010, only the contribution rate that applied to the majority of members was recorded. This means that caution should be exercised when comparing the figures for 2010 and onwards with earlier estimates 5. Prior to 2013 Defined Contribution (DC) pension schemes could classify themselves in OPSS as either contracted out or not contracted out of the additional state pension. The Pensions Act 2007 abolished the option for DC pensions to contract out of the additional state pension, with effect from April 2012. 2012 data may not fully reflect the impact of this change.
