The difference between  the actual employer contributions paid of €166 million in 2012 and the expectation of €98 million included in the 2011 Annual Report is largely attributable to  accelerated funding requirements in certain of the Group’s schemes which could not have been anticipated at the time of preparation of the year-end 2011 financial  statements. Employer contributions are reflected in the reconciliation of scheme assets as paid. 112 CRH
