4.3 Capital management

The capital structure consists of the following components:

• Structural availability of €100 million to €200 million of undrawn committed facilities out of our revolving credit facility (reference is made to note 4.4)
• Structural funding via a combination of public and bank debt, with a risk-weighted mix of fixed and floating interest
• Cash pooling systems that ensure optimal cash requirements for the PostNL Group by facilitating centralised funding and surplus cash concentration at group level
• Tax-optimal internal and external funding focused on optimising the cost of capital for PostNL, within boundaries that are sustainable on a long-term basis.
