The surplus amounts shown above are included in the balance sheet as “Receivables and other assets”. See note 17. Deficits are shown in the balance sheet within “Provisions (including post-retirement benefits)”. See note 26. Funding policy and contributions to plans The Group reviews the funding position of its pension plans on a regular basis and considers whether to provide funding above the minimum

level required in each country. In Canada and the US, the minimum level is prescribed by legislation. In the UK and Switzerland, the minimum

level is negotiated with the local trustee in accordance with the funding guidance issued by the local regulators. In deciding whether to provide

funding above the minimum level, we consider other possible uses of cash elsewhere, the local sponsoring entity’s tax situation and any

strategic advantage we might obtain. The Group does not generally pre-fund post-retirement healthcare arrangements.
