need the following: -  
 
- what a centralised treasury operation of an international bank is
and how it works?
 
- what a decentralised treasury operation of an international bank is
and how it works?
 
- Pros and cons of using a centralised structure, as well as pros and
cons of a decentralised structure?
 
- even some good links of information on centralised and decentralised
treasury management functions of banks would be appreciated.
 
THANKS
