17. Overview – Global Petrochemical Industry (1st Half 2003)
Raw materials prices remained at high levels;
Iraq War;
SARS epidemic in Asia:
. Temporary slowdown in the international polymers market, due to a
20% reduction in imports by China;
. Drop in inventory levels – higher order book backlog;
. An expectation for a recovery in imports by China in August-
September 2003, which could place upward pressure on prices in Asia.

18. Overview – Global Petrochemical Industry (1st Half 2003)
However, 2003 brought good news too...
The Iraq War ended without significant damage to oil fields;
Raw materials prices showed a downward trend;
The end of the SARS epidemic could signify a recovery in demand in
Asia, particularly in China. Prices could rise in the region;
Expectation of gradual recovery among the world’s leading economies;
Limited capacity expansion among producers.

35. Petrochemical Industry: Positive outlook
Despite unexpected issues such as SARS, 2003 is expected to be a
transition period to a new level of profitability;
Sector recovery should begin to accelerate in 2004; higher profitability;
Peak profitability (“fly-up”) is expected in 2005;
The outlook for 2006 and 2007 is positive given the limited amount of
capacity coming on line;
A downturn is expected in 2008; however, it should be softer than past
cycles (depending on investment levels);
The main future profitability driver will come from changes as a result
of: Consolidation + Low energy prices + Lower investment levels
The next cycle in the petrochemical industry could be the best in 25 years!
