(1)  Each Ordinary Share is represented by two American Depositary Shares
     ("ADSs"), which are the securities that are publicly traded.  Net income
     per Ordinary Share is therefore, within rounding, two times net income per
     equivalent ADS.

NOTE:  Fully diluted net income per ordinary share is presented on the face of
the Consolidated Statements of Operations since it is not materially different
from primary net income per ordinary share.
