On Infineon:

Siemens started to spin off several enterprises - one of them is Infineon, basically a chip maker.

Although this company is a separate entity now (that's why the separate financial statement) Siemens still holds the majority shares (that's why it's still in the annual report).

On the exchange rate:

A weak Euro means that all transactions outside the Euro bloc carry a higher profit margin (in Euros) than with a stronger Euro - that is for all products produced within the Euro bloc and then shipped outside. So to do the analysis you would have to determine where products are produced and then where are they shipped to. Let us know what your results are.
Mr Bush wants a stronger Euro to reap more profits off exports to the Euro bloc.
