Following the introduction of Law 296/06, leaving entitlements in Italy (trattamento di fine rapporto) accrued from 1 January 2007 and paid in to supplementary pension funds or the fund established by INPS are recognized under “Defined contribution plans and social security contributions”, while adjustments to the provision for leaving entitlement accrued before 1 January 2007 are recognized under “Leaving entitlement and other defined benefit plans” (see also Note 19).

Social security contributions represent amounts paid by the Company to social security and insurance agencies in relation to short-term benefits for situations such as illness, injury and compulsory maternity leave.

Other personnel costs related mainly to accruals for variable compensation, leaving incentives and insurance.
