6. Please discuss in greater detail the business reasons for the
changes between periods in the gross margin and operating income
of
each of your segments discussed in Note 10 of your financial
statements, along with the amounts shown in the corporate line
item.
In doing so, please disclose the amount of each significant change
in
line items between periods and the business reasons for it.  In
circumstances where there is more than one business reason for the
change, attempt to quantify the incremental impact of each
individual
business reason discussed on the overall change in the line item.
Also quantify the impact of the business reasons you discuss
throughout MD&A.  See Item 303(a)(3) of Regulation S-K and
Financial
Reporting Codification 501.04.

Liquidity and Capital Resources, page 6

7. Please include a table summarizing all of your contractual
obligations, including operating lease commitments, purchase
obligations, and other long-term liabilities.  The table should
also
include estimated interest payments on your debt, estimated
payments
under interest rate swap agreements, and planned funding of
pension
and other postretirement benefit obligations in order to increase
transparency of cash flow.   Please also disclose any assumptions
you
made to derive these amounts.  See Item 303(a)(5) of Regulation S-
K.

Financial Statements

Note 1. Significant Accounting Policies and Procedures, page 13

8. Please disclose the types of expenses that you include in the
cost
of sales line item and the types of expenses that you include in
the
selling, general and administrative expenses line item.  Please
disclose whether you include inbound freight charges, purchasing
and
receiving costs, inspection costs, warehousing costs, internal
transfer costs, and the other costs of your distribution network
in
the cost of sales line item.  With the exception of warehousing
costs, if you currently exclude a portion of these costs from cost
of
sales, please disclose:

?	in a footnote the line items that these excluded costs are
included in and the amounts included in each line item for each
period presented, and

?	in MD&A that your gross margins may not be comparable to
those
of other entities, since some entities include all of the costs
related to their distribution network in cost of sales and others
like you exclude a portion of them from gross margin, including
them
instead in a line item, such as selling, general and
administrative
expenses.

Revenue Recognition, page 13

9. You disclose that revenues are recognized when products are
shipped to customers.  Please disclose in your revenue recognition
policy whether your stated shipping terms are FOB shipping point
or
FOB destination pursuant to your sales agreements with customers.
In
addition, please disclose whether your sales agreements contain
right
of inspection or acceptance provisions and whether you replace
goods
damaged or lost in transit.  Even if your sales agreements state
that
title passes upon shipment, customer acceptance provisions or a
history of your replacing goods damaged or lost in transit may
also
make the recognition of revenue upon delivery to and acceptance by
the customer more appropriate.  See the Interpretive Response to
Question 3 of SAB Topic 13:A.3.b.

Stock Based Compensation, page 14

10. We note that you did not adopt fair value accounting for
employee
stock options under SFAS 123.  Regardless of the method used to
account for stock-based employee compensation arrangements, your
financial statements should include the disclosures specified in
paragraphs 46 to 48 of SFAS 123 in the Significant Accounting
Policies and Procedures note.  See SFAS 123, paragraph 45, as
amended
by SFAS 148 for guidance.

Note 2. Balance Sheet Components, page 14

11. Please breakout the machinery and equipment line item into
smaller and more meaningful components.  In addition, we see from
page 13 that the range of useful lives for your machinery and
equipment of 3 to 20 years is very broad.  Please separately
disclose
the range of useful lives for each new category presented.  For
categories that still have very broad useful lives, you should
separately discuss the types of assets that fall in each part of
the
range.

Note 6. Earnings Per Share, page 16

12. In accordance with SFAS 128, paragraph 40c, please disclose
the
securities that could potentially dilute basic EPS in the future
that
were not included in the computation of diluted EPS because to do
so
would have been antidilutive for the periods presented.

Note 10. Segment Information, page 18

13. Disclose segment tax expense information pursuant to SFAS 131,
paragraph 27, or explain to us why it is not necessary to do so.
