Accounting Changes And Error Corrections [Abstract]
Recent Accounting Standards	(11) Recent Accounting Standards In August, 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments, which adds or clarifies guidance of the classification of certain cash receipts and payments in the statement of cash flows with the intent to alleviate diversity in practice for classifying various types of cash flows. This ASU is effective for annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted. We are currently evaluating the impact of this ASU on our statement of cash flows. In March, 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”, which amends the accounting for employee share-based payment transactions to require recognition of the tax effects resulting from the settlement of stock-based awards as income tax expense or benefit in the income statement in the reporting period in which they occur. We have adopted this new standard, which is effective for annual reporting periods beginning after December 15, 2016, as of January 1, 2017. The impact of ASU 2016-09 to date is explained above in Note 10-Income Taxes. Since the impact of ASU 2016-09 on our future Condensed Consolidated Statements of Income and Condensed Consolidated Statements of Cash Flows is dependent upon the timing of stock option exercises, and the market price of our stock at the time of exercise, we are unable to estimate the impact this adoption will have on our future financial statements. In May 2014 and March 2016, the FASB issued ASU 2014-09 and ASU 2016-08, “Revenue from Contracts with Customers (Topic 606)” and “Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net)”, respectively, which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosures. The FASB updated the new revenue standard by clarifying the principal versus agent implementation guidance, but does not change the core principle of the new standard. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016; however, in July 2015, the FASB approved a one-year deferral of this standard, with a new effective date for fiscal years beginning after December 15, 2017. We are currently in the process of assessing and analyzing the various sources of revenue and plan to use a portfolio approach as a practical expedient to account for patient contracts. We have a team in place to lead the implementation of the new standard, including the evaluation of our systems and internal controls to ensure adequacy of data and information needed for adoption, as well as assessing the potential impact of the new standard on various reimbursement programs in which our hospitals participate. We anticipate the most significant change will be how the estimate for the allowance for doubtful accounts will be recognized under the new standards. Under the current standards, our estimate for amounts not expected to be collected based upon our historical experience have been included within net revenue. Under the new standards, our estimate for amounts not expected to be collected based on historical experience will continue to be recognized as a reduction to net revenue. However, subsequent changes in estimate of collectability due to a change in the financial status of a payor, for example a bankruptcy, will be recognized as bad debt expense in operating charges. We will continue to evaluate the impact that the adoption of this ASU may have on our consolidated financial statements and related disclosures. In February, 2016, the FASB issued ASU 2016-02, “Leases (Topic 842): Amendments to the FASB Accounting Standards Codification (“Update 2016-02”), which requires an entity to recognize lease assets and lease liabilities on the balance sheet and to disclose key qualitative and quantitative information about the entity’s leasing arrangements. This update is effective for annual reporting periods beginning after December 15, 2018 with early adoption permitted. A modified retrospective approach is required. Upon adoption of this new standard, we will recognize significant right of use assets and lease obligation liabilities on the consolidated balance sheet as a result of our operating lease obligations. Operating lease expense will still be recognized on a straight-line basis over the remaining life of the lease within lease and rental expense in the consolidated statements of income. We are currently evaluating the effect that ASU 2016-02 will have on our consolidated financial statements and related disclosures. In January, 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment” (“ASU 2017-04”), which removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for the annual and interim periods beginning January 1, 2020 with early adoption permitted, and applied prospectively. We do not expect ASU 2017-04 to have a material impact on our financial statements. In January, 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805) - Clarifying the Definition of a Business” to clarify the definition of a business in order to allow for the evaluation of whether transactions should be accounted for as acquisitions or disposals of assets or businesses. ASU 2017-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The future impact of ASU 2017-01 will be dependent upon the nature of future acquisitions or dispositions made by us, if any. From time to time, new accounting guidance is issued by the FASB or other standard setting bodies that is adopted by the Company as of the effective date or, in some cases where early adoption is permitted, in advance of the effective date. The Company has assessed the recently issued guidance that is not yet effective and, unless otherwise indicated above, believes the new guidance will not have a material impact on our results of operations, cash flows or financial position.

From time to time, new accounting guidance is issued by the FASB or other standard setting bodies that is adopted by the Company as of the effective date or, in some cases where early adoption is permitted, in advance of the effective date. The Company has assessed the recently issued guidance that is not yet effective and, unless otherwise indicated above, believes the new guidance will not have a material impact on our results of operations, cash flows or financial position.
