MAY-04 Reconciliations and definitions

”Group profit from Operations” is reconciled to ”Income before income taxes” of Operations under ”Reconciliation to financial statements” on the table ”Segment information.” See ”Financial Reports/Fiscal 2004, Quarter 2 / Financial Statements” at our Investor Relations website under www.siemens.com

”ROE” (Return on equity) margin for SFS was calculated as SFS’ income before income taxes divided by the allocated equity for SFS. Allocated equity for SFS as of September 30, 2003 was €1.080 billion. See also Siemens’ Form 20-F at our Investor Relations website under www.siemens.com

The allocated equity for SFS is determined and influenced by the respective credit ratings of the rating agencies and by the expected size and quality of its portfolio of leasing and factoring assets and equity investments and is determined annually. This allocation is designed to cover the risks of the underlying business and is in line with common credit risk management standards in banking. The actual risk profile of the SFS portfolio is monitored and controlled monthly and is evaluated against the allocated equity.

Siemens ties a portion of its executive incentive compensation to achieving economic value added (EVA) targets. EVA measures the profitability of a business (using Group profit for the Operating Groups and income before income taxes for the Financing and Real estate businesses as a base) against the additional cost of capital used to run a business, (using Net capital employed for the Operating Groups and risk-adjusted equity for the Financing and Real estate businesses as a base). A positive EVA means that a business has earned more than its cost of capital, and is therefore defined as value-creating. A negative EVA means that a business is earning less than its cost of capital and is therefore defined as value-destroying. Other organizations that use EVA may define and calculate EVA differently.

A reconciliation of EVA may be found on our Investor Relations website under www.siemens.com
