New Accounting Standards Pending Adoption (Unaudited)	24. New Accounting Standards Pending Adoption (Unaudited) Income Taxes — In October 2016, the FASB issued amended authoritative guidance associated with the timing of recognition of income taxes for intra-entity transfers of assets other than inventory. The amended guidance requires the recognition of income taxes when the transfer of the asset occurs, which replaces current U.S. Generally Accepted Accounting Principles (“GAAP”) that defers the recognition of income taxes until the transferred asset is sold to a third party or otherwise recovered through use. The amended guidance is effective for the Company on January 1, 2018, with early adoption permitted. We are in the process of assessing the provisions of this amended guidance; however, we currently do not expect that the adoption of this amended guidance will have a material impact on our consolidated financial statements. Statement of Cash Flows — In August 2016, the FASB issued amended authoritative guidance associated with the classification of certain cash receipts and cash payments in the statement of cash flows. In November 2016, the FASB issued additional guidance on the presentation of restricted cash and cash equivalents in the statement of cash flows. The objective of both amendments was to reduce existing diversity in practice. The amended guidance is effective for the Company on January 1, 2018, with early adoption permitted. We are in the process of assessing the provisions of this amended guidance; however, we currently do not expect that the adoption of this amended guidance will have a material impact on our consolidated financial statements. Financial Instrument Credit Losses — In June 2016, the FASB issued amended authoritative guidance associated with the measurement of credit losses on financial instruments. The amended guidance replaces the current incurred loss impairment methodology of recognizing credit losses when a loss is probable, with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to assess credit loss estimates. The amended guidance is effective for the Company on January 1, 2020, with early adoption permitted beginning January 1, 2019. We are assessing the provisions of the amended guidance and evaluating the timing and impact on our consolidated financial statements. Stock Compensation — In March 2016, the FASB issued amended authoritative guidance associated with stock-based compensation as part of its simplification initiative to reduce the cost and complexity of compliance with GAAP, while maintaining or improving the usefulness of the information provided. The amended guidance changes both the accounting and financial reporting for certain income tax impacts of stock-based compensation. All excess tax benefits and tax deficiencies will be required to be recognized as an income tax benefit or provision rather than as a component of equity. The guidance also provides for changes in the calculation of forfeitures related to the expense of stock-based compensation. The amended guidance is effective for the Company on January 1, 2017. The adoption of this amended guidance will not have a material impact on our consolidated financial statements. Leases — In February 2016, the FASB issued amended authoritative guidance associated with lease accounting. The amended guidance requires the recognition of lease assets and lease liabilities on the balance sheet for those leases with terms in excess of 12 months and currently classified as operating leases. The disclosure of key information about leasing arrangements will also be required. The amended guidance is effective for the Company on January 1, 2019, with early adoption permitted. We are assessing the provisions of the amended guidance and evaluating the timing and impact on our consolidated financial statements and disclosures. Financial Instruments — In January 2016, the FASB issued amended authoritative guidance associated with the recognition and measurement of financial assets and liabilities. The amended guidance will require certain equity investments that are not consolidated to be measured at fair value with changes in fair value recognized in net income rather than as a component of accumulated other comprehensive income. The amended guidance is effective for the Company on January 1, 2018, with early adoption permitted. We are assessing the provisions of the amended guidance and evaluating the timing and impact on our consolidated financial statements. Revenue Recognition — In May 2014, the FASB issued amended authoritative guidance associated with revenue recognition. The amended guidance requires companies to recognize 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. Additionally, the amendments will require enhanced qualitative and quantitative disclosures regarding customer contracts. The amended guidance associated with revenue recognition is effective for the Company on January 1, 2018. The amended guidance may be applied retrospectively for all periods presented (“full retrospective method”) or retrospectively with the cumulative effect of initially applying the amended guidance recognized at the date of initial adoption (“modified retrospective method”). To assess the impact of the standard, we utilized internal resources to lead the implementation effort and supplemented them with external resources. Our internal resources read the amended guidance, attended trainings and consulted with non-authoritative groups to assist with interpretation of the amended guidance. Surveys were sent to and returned by all operating segments to assess the potential impact of the amended guidance and to tailor specific procedures to evaluate the potential impact. Based on the results of these surveys, we judgmentally selected a sample of contracts based on size and specifically identified contract traits that could be accounted for differently under the amended guidance. We also selected a representative sample of contracts to corroborate the survey results. We have completed our preliminary review of all contracts and are in the process of compiling and summarizing the results to determine whether additional review and analysis is necessary. Based on our work to date, we believe we have identified all material contract types and costs that may be impacted by this amended guidance. We expect to quantify and disclose the expected impact, if any, of adopting this amended guidance in the third quarter Form 10-Q. While we are still evaluating the impact of the amended guidance, we currently do not expect it to have a material impact on operating revenues. Upon adoption of the amended guidance, we anticipate recognizing an asset from the capitalization of sales incentives as contract acquisitions costs. Under the amended guidance, sales incentives will be capitalized and amortized over the expected life of the customer relationship. Currently, the Company expenses approximately $65 million in sales incentives annually. As noted above, we are still evaluating other possible impacts on our consolidated financial statements, including potential changes in the classification of certain revenue streams currently reported on a gross basis and on our disclosures. The Company is also currently planning to adopt the amended guidance using the modified retrospective method as of January 1, 2018.
