				Response to Comment Letter dated September 22, 2006

Ladies and Gentlemen:

This letter is written in response to the letter dated September 22, 2006 from Mr. John Hartz, commenting on our responses dated August 2, 2006 and August 28, 2006. The Company’s responses follow, set forth under the corresponding comments from Mr. Hartz’s letter.

Form 10-K for the period ended October 29, 2005

Note 5 – Fixed Asset Charge, page 40

At this time we have no further comments regarding the fixed asset charge, pending the review of your Form 10-K/A.

On October 30, 2006, we filed our Form 10-K/A addressing the restatement and comments including in your previous correspondence.

Note 17 – Segment Information, page 50

We note your response to prior comment two, and appreciate the additional information you have provided. It continues to appear to us that each “component” of your segments is an operating segment as defined in paragraph 10 of SFAS 131. We note that you believe that your components are not operating segments because “these reports help explain the results of our segments, not as a basis for assessing or analyzing the performance of each component itself”. It appears to us that this represents a semantic distinction that does not eliminate certain clear factors indicating that the components are operating segments. In particular:

•

Each component engages in business activities from which it may earn revenues and incur expenses. We direct you to sections I, II, III, IV and V of the Spartech

			*Corporation Monthly Reporting Package. Included therein are sales, material margins, gross margins and operating earnings. This information is provided in considerable detail, See section V.;*

	•		*Discrete financial information is available. See above;*

	•		*The CODM regularly reviews this information to make decisions about resources to be allocated to the components and assess their performance;*

			We assume that you agree with the first two points, but may have a different opinion regarding the third. We note that the Spartech Corporation Monthly Reporting Package is regularly provided to the CODM. This fact leads to the conclusion that it is intended for him and as such it is intended for him to “review”. You indicated that each segment manager is responsible for presenting transactions, projects or initiatives that meet certain return expectations for his segment and that this may require an integration of several segment components to accomplish these objectives. It appears to us that there are distinct differences between each component even when reviewing these objectives. We also note that in order to discuss the performance of the segment which the managers are responsible they need to refer to events and fluctuations of the component parts, which leads us to believe that these components are effectively being evaluated separately.

			It is not essential that this information be the only method in which the components are assessed in how resources are allocated, but it seems clear that the performance of each component is an element of assessing performance and considering transactions, projects or initiatives that meet certain return expectations, and therefore are used in resource allocation.

			We also note that you intend to revise the reporting provided in your Board Package; however, revising this information does not change what has already been reported and how you have traditionally viewed your business and used the component level information to manage and allocate your resources. Not withstanding the above, we also believe that changing the information provided the Board does not clearly indicate that the component information will not be used to manage your business and allocate your resources. For example, considering the overall nature of your business and the method of managing it, we would assume that the definition of the CODM would have to be expanded in that event and the components would remain your operating segments as defined in SFAS 131. See paragraph 12

			*We ask that you reconsider your current views as it appears that your components are operating segments.*
