The key performance criteria for Corporate Center are quality of services, business alignment and cost control.
The operating income of the Corporate Center is derived from interest on non-allocated economic capital
and non attributable income. The decrease in 2004 is due to lower internal interest rates, the lower average
capital base of NIBCapital and an impairment in the value of a strategic partnership. Provisions in 2004
include the indemnification of investors in an investment product.
The decrease in expenses for support & services is the result of tight cost control and rationalisation of
processes. The increase in non-attributable expenses stemmed fully from expenses for the introduction of
IFRS in 2005. In 2003 non-attributable expenses included one-off relocation costs of Corporate Finance to
our offices in The Hague.
