8. 7 Mercer Increased Recognition of Expected Investment Returns  Allow for actual investment strategy  Central return expectations  Investment return “offset” to deficit contributions  Greater reliance on investment outturn  Increased risk of future increase in contributions  Assumes investment strategy returns over full duration of recovery period  Option only for High Covenant bodies

9. 8 Mercer Criteria for applying investment return offset  Strong covenant employer Administering Authority determines sufficient covenant to support the anticipation of investment returns, based on the current investment strategy, over the duration of the recovery period.  Only applicable as part of deficit recovery plan No investment return adjustment for bodies with a funding surplus.  Minimum contribution requirements Adjusted required contributions subject to minimum of both the current contributions from 2004 valuation, and the future service cont rate.  Long term time horizon Not generally applicable for closed bodies, or with otherwise limited duration.
