Significant Accounting Policies [Abstract]
Significant Accounting Policies	Note 2. Significant Accounting Policies The Company’s significant accounting policies are described in Note 2 to the audited consolidated financial statements included in the Company’s 2015 Form 10-K. Other than the addition below, there have been no material changes to the significant accounting policies for the three and six months ended June 30, 2016. Restricted Cash Restricted cash consists of cash held in trust as collateral under the Company’s automobile, general liability and workers’ compensation insurance program. Newly Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” to provide a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This model supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” Entities have the option of using either a full retrospective or modified approach to adopt the guidance. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted for fiscal years, and interim period within those years, beginning after December 15, 2016. The Company is currently evaluating the impact of adopting ASU 2014-09. In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” to change how entities measure certain equity investments, to require the disclosure of changes in the fair value of financial liabilities measured under the fair value option that are attributable to a company’s own credit, and to change certain other disclosure requirements. The changes in ASU 2016-01 specifically require that the changes in fair value of all investments in equity securities be recognized in net income. The Company is impacted as unrealized gains or losses on the Company’s available-for-sale securities are currently recognized in other comprehensive income. The amendments in ASU 2016-01 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and will be adopted prospectively. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which is the final standard on accounting for leases. While both lessees and lessors are affected by the new guidance, the effects on lessees are much more significant. The most significant change for lessees is the requirement under the new guidance to recognize right-of-use assets and lease liabilities for all leases not considered short-term leases. Entities are required to use a modified retrospective approach to adopt the guidance. The amendments in ASU 2016-02 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2016-02. In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” to require the recognition of the income tax effects of share-based awards in the income statement when the awards vest or are settled and the presentation of excess tax benefits as an operating activity on the statement of cash flows as part of the FASB’s simplification initiative. Under previous guidance, an entity generally recorded excess tax benefits and certain tax deficiencies in additional paid-in capital instead of through income tax expense or benefit in the income statement and presented excess tax benefits as a financing activity rather than an operating activity in the statement of cash flows. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. As allowed, the Company has elected to early adopt the amendments of ASU 2016-09. The adoption of ASU 2016-09 has been accounted for as a change in accounting principle prospectively for the income statement effect, as required, and retrospectively for the cash flow statement effect, as allowed. As a result of the implementation of ASU 2016-09, $10 million of excess tax benefits for the six months ended June 30, 2015 were retrospectively presented as an operating activity within the condensed consolidated statements of cash flows.
