Basis of Financial Statement Preparation [Abstract]  
Use of Estimates, Policy [Policy Text Block]
Use of Estimates in Financial Statement Preparation--The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect reported amounts. Our consolidated financial statements include amounts that are based on management’s best estimates and judgments.  Estimates are used for, but not limited to, accounts receivable valuation, depreciable lives of fixed assets, self-insurance accruals, income taxes and revenue recognition. Actual results could differ from those estimates.
