Accounting Policies [Abstract]

Use of Estimates, Policy [Policy Text Block]

             We must make estimates and assumptions to prepare the consolidated condensed financial statements in conformity with U.S. generally accepted accounting principles. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities in the consolidated condensed financial statements and the reported amount of revenue and expenses during the reporting period. These estimates are primarily related to insurance and claims accruals and depreciation. Ultimate results could differ from these estimates.

New Accounting Pronouncements, Policy [Policy Text Block]

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard, which is effective for the first quarter of 2018, will replace most existing revenue recognition guidance required by U.S. generally accepted accounting principles. The adoption of this standard is not expected to have a significant impact on our consolidated condensed balance sheets, statements of operations or statements of cash flows.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, “Leases” which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance also requires additional disclosures related to leasing transactions. The standard is effective for the first quarter of 2019. The adoption of this standard is not expected to have a significant impact on our consolidated condensed balance sheets, statements of operations or statements of cash flows.

In March 2016, the FASB issued Accounting Standards Update No. 2016-09, “Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting” which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The standard is effective for the first quarter of 2017. The adoption of this standard will result in an increase or decrease to our provision for income taxes each quarter based on the actual increase in our stock price compared with the grant-date fair value of the quarter’s exercised options and vested performance unit awards. The adoption of the other provisions of this standard is not expected to have a significant impact on our consolidated condensed balance sheets, statements of operations or statements of cash flows.
