and FIL, or trusts for their benefit, own shares of FIL voting 
stock with the right to cast approximately 47% of the total 
votes which may be cast by all holders of FIL voting stock.  
FMR LLC and FIL are separate and independent corporate 
entities, and their Boards of Directors are generally composed 
of different individuals.

	FMR LLC and FIL are of the view that they are not 
acting as a "group" for purposes of Section 13(d) under the 
Securities Exchange Act of 1934 (the "1934" Act) and that 
they are not otherwise required to attribute to each other the 
"beneficial ownership" of securities "beneficially owned" by 
the other corporation within the meaning of Rule 13d-3 
promulgated under the 1934 Act.  Therefore, they are of the 
view that the shares held by the other corporation need not be 
aggregated for purposes of Section 13(d). However, FMR 
LLC is making this filing on a voluntary basis as if all of the 
shares are beneficially owned by FMR LLC and FIL on a joint 
basis.
