New Accounting Standards Pending Adoption
New Accounting Standards Pending Adoption	22. New Accounting Standards Pending Adoption (Unaudited) Income Taxes — In October 2016, the FASB issued ASU 2016‑16 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 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 and will not have a material impact on our consolidated financial statements. Statement of Cash Flows — In August 2016, the FASB issued ASU 2016‑15 associated with the classification of certain cash receipts and cash payments in the statement of cash flows. In November 2016, the FASB issued ASU 2016‑18 associated with 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 and, upon adoption, the principal change for the Company will be in the presentation of restricted cash and cash equivalents in the statement of cash flows, which will include substantially all of the restricted trust and escrow accounts reflected on our Consolidated Balance Sheets. Financial Instrument Credit Losses — In June 2016, the FASB issued ASU 2016‑13 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 this amended guidance and evaluating the impact on our consolidated financial statements. Leases — In February 2016, the FASB issued ASU 2016‑02 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. We are assessing the provisions of this amended guidance and we have (i) formed an implementation work team; (ii) performed training for the various organizations that will be most affected by the new standard and (iii) acquired a software solution to manage and account for leases under the new standard. We are evaluating the impact of this amended guidance on our consolidated financial statements. Financial Instruments — In January 2016, the FASB issued ASU 2016‑01 associated with the recognition and measurement of financial assets and liabilities. The amended guidance will require certain equity investments that are not consolidated and not accounted for under the equity method 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 (loss). The amended guidance is effective for the Company on January 1, 2018 and will not have a material impact on our consolidated financial statements. Revenue Recognition — In May 2014, the FASB issued ASU 2014‑09 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”). The Company is currently planning to adopt the amended guidance using the modified retrospective method as of January 1, 2018. 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 other accounting professionals 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. 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 currently do not expect the amended guidance to have a material impact on operating revenues. However, upon adoption of the amended guidance, certain sales incentives will be capitalized and amortized to selling, general and administrative expenses over the expected life of the customer relationship. Under current guidance, sales incentives are expensed as earned to selling, general and administrative expenses. Additionally, the amended guidance resulted in a change in who we identify as a customer for certain arrangements. We anticipate payments to these customers will be a reduction in operating revenues. Under current guidance, these payments are recorded as operating expenses.
