| Amendment Flag | true | ||
| Amendment Description | This Amendment No. 1 reflects a correction of an error in the presentation of the proceeds from the sale of by-products from the Company’s manufacturing operations as sales rather than a reduction of cost of sales in the Consolidated Statements of Operations. The Company has also corrected an error in the Consolidated Statements of Cash Flows to classify proceeds and payments related to a short term financing arrangement as a financing activity rather than as an operating activity. | ||
