Form 10-K for the Fiscal Year Ended September 30, 2004

Financial Statements, page 22

Inventories, page 29

1. Please refer to your response to prior comment 1 from our June
13,
2005 letter.  We note that adjustment A in Exhibit A reduces your
inventory reserve in 2002 for lower of cost or market adjustments
or
for excess reserve amounts.  A write-down of inventory to the
lower
of cost or market at the close of a fiscal period creates a new
cost
basis that subsequently cannot be marked up based on changes in
underlying facts and circumstances.  Please tell us the nature of
this decrease to your reserve and discuss your considerations of
the
above and footnote 2 to ARB 43 and SAB Topic 5.BB.


      As appropriate, please respond to this comment within 10
business days or tell us when you will provide us with a response.
Please furnish a cover letter that keys your response to our
comments
and provides any requested supplemental information.  Detailed
cover
letters greatly facilitate our review.  Please file your cover
letter
on EDGAR.  Please understand that we may have additional comments
after reviewing your response to our comment.

      You may contact Heather Tress, Staff Accountant, at (202)
551-
3624 or me at (202) 551-3604 if you have questions regarding
comments
on the financial statements and related matters.  In this regard,
do
not hesitate to contact Michele Gohlke, Accounting Branch Chief,
