| Asset volatility  | The liabilities are calculated using a discount rate set with reference to corporate  | 
| bond yields. If assets underperform this yield, this will create a deficit. The Scheme  | |
| previously held a significant proportion of gilt and bond assets which limits volatility  | |
| and risk in the short term. The allocation of assets is monitored to ensure it remains  | |
| appropriate given the Scheme’s long-term objectives.  | |
| Inflation risk  | A proportion of the Scheme’s benefit obligations are linked to inflation, and higher  | 
| inflation leads to higher liabilities (although, in most cases, caps on the level of  | |
| inflationary increases are in place to protect against extreme inflation). The  | |
| majority of the assets are either unaffected by or only loosely correlated with  | |
| inflation, meaning that an increase in inflation will also increase the deficit.  | |
| Change in  | A decrease in corporate bond yields will increase the value placed on the Scheme’s  | 
| bond yields  | liabilities for accounting purposes, although this will be partially offset by an  | 
| increase in the value of the Scheme’s bond holdings.  | |
| Life expectancy  | The majority of the Scheme’s obligations are to provide benefits for the lifetime of  | 
| the member, so increases in life expectancy will result in an increase in the liabilities.  |
