Organization Consolidation And Presentation Of Financial Statements [Abstract]

Basis Of Accounting Policy [Policy Text Block]

The condensed consolidated financial statements included herein are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States for interim financial reporting and the United States Securities and Exchange Commission regulations. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the financial statements reflect all adjustments (consisting only of normal recurring adjustments, except as discussed below) which are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods. Certain reclassifications of prior year data have been made to improve comparability. The results for the three months ended March 31, 2013 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the Company's Annual Report filed on Form 10-K for the year ended December 31, 2012.

Revenue Recognition Accounting Policy, Gross and Net Revenue Disclosure [Policy Text Block]

As part of the Company's chemical management services, certain third-party product sales to customers are managed by the Company. Where the Company acts as the principal, revenue is recognized on a gross reporting basis at the selling price negotiated with customers. Where the Company acts as an agent, such revenue is recorded using net reporting as service revenues, at the amount of the administrative fee earned by the Company for ordering the goods.

Comprehensive Income Policy [Policy Text Block]

During the first quarter of 2013, the Company adopted the Financial Accounting Standards Board's (“FASB's”) guidance regarding the disclosure of reclassifications from Accumulated Other Comprehensive Income (Loss) (“AOCI”). The guidance requires the disclosure of significant amounts reclassified from each component of AOCI, the related tax amounts and the income statement line items affected by the reclassifications, either parenthetically on the Condensed Consolidated Statement of Comprehensive Income or in the Notes to the Condensed Consolidated Financial Statements. The Company elected to present the information in the Notes to the Condensed Consolidated Financial Statements, and the adoption of this guidance did not have a material impact on the Company's results or financial condition. See Note 9 of Notes to Condensed Consolidated Financial Statements.
