Recent Accounting Pronouncements	Recent Accounting Pronouncements Share-Based Payments: In March 2016, amended guidance was issued for employee share-based payment awards. The amended guidance makes several modifications related to the accounting for forfeitures, employer tax withholding on share-based compensation and excess tax benefits or deficiencies. The amended guidance also clarifies the statement of cash flows presentation for share-based awards. The amended guidance is effective for us prospectively commencing in the first quarter of 2018. Early adoption is permitted. Deferred Income Taxes: In November 2015, amended guidance was issued for the balance sheet classification of deferred income taxes. The amended guidance requires the classification of all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Early adoption is permitted. In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03, "Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Currently, debt issuance costs are recognized as deferred charges and recorded as other assets. The guidance is effective for annual and interim periods beginning after December 15, 2015 with early adoption permitted and is to be implemented retrospectively. Adoption of the new guidance will only affect the presentation of the Company's consolidated balance sheets and will have no impact to our financial statements. Management does not anticipate that the adoption of these standards will have a material impact on the financial statements. The preparation of these financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related intangible assets, income taxes, insurance obligations and contingencies and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other resources. Actual results may differ from these estimates under different assumptions or conditions. The Financial Statements presented herein have been prepared by us in accordance with the accounting policies described in our December 31, 2015 Annual Report and should be read in conjunction with the Notes to Financial Statements which appear in that report. In the opinion of management, the information furnished in these interim financial statements reflects all adjustments necessary for a fair statement of the financial position and results of operations and cash flows as of and for the three and six-month periods ended June 30, 2016 and 2015. All such adjustments are of a normal recurring nature. The Financial Statements do not include some information and notes necessary to conform to annual reporting requirements.
