Dear Ms. Long:

I am writing to respond to your comment letter dated November 26, 2007, relating to the captioned filing.

Form 10-K for the fiscal year ended December 31, 2006

Business, page 2

1.

We note the discussion of various items under Risk Factors for which segment level disclosure appears to be required by Item 101(c)(1) of Regulation S-K. For example, your Business section contains little discussion of the sources and availability of raw materials, your reliance upon individual customers, and competitive conditions and the methods by which you compete, despite some general disclosure of these matters in various risk factors. In future filings, please disclose the information in subparagraphs (c)(1)(i)-(ix) of item 101 to the extent such information is material to your business taken as a whole.

Response: In future filings we will disclose the information required in subparagraphs (c)(1)(i)-(ix) of Item 101 to the extent such information is material to our business taken as a whole.

In addition please disclose the extent to which changes in net sales are influenced by changes in the price or volume sold of your products, or to the introduction of new products. Refer to paragraphs (a)(3)(i) and (a)(3)(iii) to Item 303 of Regulation as well as Instruction 4 thereto.

Response: In future filings we will expand our disclosure to discuss the events that affected our components of income from continuing operations and the extent to which changes in net sales are influenced by changes in price or volume sold of our products, or to the introduction of new products as noted in paragraphs (a)(3)(i) and (a)(3)(iii) to Item 303 of Regulation S-K.
