Notes to Financial Statements [Abstract]
Consolidation	The consolidated condensed financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions have been eliminated. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to use judgment in the application of accounting policies, including making estimates and assumptions. We base estimates on the information available to us at the time, our experience and on various other assumptions believed to be reasonable under the circumstances. Adjustments may be made in subsequent periods to reflect more current estimates and assumptions about matters that are inherently uncertain. Actual results may differ. For a discussion of the Company’s significant accounting policies, please see the Company’s Annual Report on Form 10-K for the fiscal year ended August 31, 2011.

Describes an entity's accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. An entity also may describe its accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.
