Recently Adopted Standards and Issued Accounting Standards	Recently Adopted and Issued Accounting Standards Recently Adopted Accounting Standards — In March 2017, the Financial Accounting Standards Board (FASB) issued new guidance on the presentation of net periodic benefit cost in the financial statements. It requires entities to disaggregate the current service cost component from the other components of net benefit cost. The total for service cost is to be presented with other current compensation costs in the income statement, while the total of the other components is to be presented outside of income from operations. We elected to early adopt this guidance as of January 1, 2017. We do not have a service cost associated with our net benefit cost, as such, the impact of adopting this new guidance was to reclassify our defined benefit pension plan expense out of operating costs and expenses and to classify it as a non-operating expense below operating income. In January 2017, the FASB issued new guidance to simplify the measurement of goodwill impairments by eliminating Step 2 from the impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to the reporting unit. We have elected to early adopt this guidance as of the beginning of 2017. In November 2016, the FASB issued new guidance to clarify the classification and presentation of restricted cash in the statement of cash flows. Under the new guidance, restricted cash and restricted cash equivalents are included in the cash and cash equivalent balances in the statement of cash flows. Additionally, changes in restricted cash and restricted cash equivalents are no longer presented as a financing cash flow activity within the statement of cash flows. We elected to early adopt this guidance as of December 31, 2016, and retrospectively applied the guidance to prior periods. The impact of adopting the new guidance was to increase cash and cash equivalents by $5.5 million and $6.6 million at March 31, 2016 and December 31, 2015, respectively, due to the reclassification from restricted cash. In March 2016, the FASB issued new guidance which simplifies the accounting for share-based compensation arrangements, including the related income tax consequences and classification on the statement of cash flows. We elected to early adopt this guidance effective January 1, 2016. The adoption used the modified retrospective transition method which had no impact on prior years. The impact of adopting this guidance was to record $14.7 million of previously unrecognized tax benefits, increasing deferred tax assets and retained earnings as of December 31, 2015. Additionally, we elected to adopt a policy of recording actual forfeitures, the impact of which was not material to current or prior periods. Recently Issued Accounting Standards — In January 2017, the FASB issued new guidance to clarify the definition of a business in ASC 805 with the intent to make application of the guidance more consistent and cost-efficient. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods therein, and must be applied prospectively. We do not expect the adoption of this guidance to affect the treatment of future acquisitions or dispositions. In August 2016, the FASB issued new guidance related to classification of certain cash receipts and payments in the statement of cash flows. This new guidance was issued with the objective of reducing diversity in practice around eight specific types of cash flows. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. We are currently evaluating the impact of this guidance on our consolidated statements of cash flows. In June 2016, the FASB issued new guidance that changes the impairment model for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that will replace today’s “incurred loss” model and generally will result in the earlier recognition of allowances for losses. For available-for-sale debt securities with unrealized losses, entities will measure credit losses in a manner similar to current practice, except that the losses will be recognized as an allowance. The guidance is effective in 2020 with early adoption permitted in 2019. We are currently evaluating the impact of this guidance on our financial statements and the timing of adoption. In February 2016, the FASB issued new guidance on the accounting for leases. Under this guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases (with the exception of short-term leases) at the commencement date. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. We are currently evaluating the impact of this guidance on our consolidated financial statements. In January 2016, the FASB issued new guidance on the recognition and measurement of financial instruments. This guidance primarily affects the accounting for equity method investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. We are currently evaluating the impact of this guidance on our consolidated financial statements. In May 2014, the FASB issued new guidance on revenue recognition. Under this new standard, an entity shall recognize revenue when it transfers 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. The standard creates a five-step process that requires entities to exercise judgment when considering the terms of the contract(s) and all relevant facts and circumstances. This standard permits the use of either the retrospective or cumulative effect transition method and will be effective for us beginning in 2018. We are currently assessing the impact this new guidance will have on our consolidated financial statements and have not yet determined a transition method. We are progressing in our process of adopting the new guidance and are working to identify all performance obligations and changes, if any, that the new guidance will have on the timing and amounts of revenue recorded. To date we are evaluating the impact, if any, that the new guidance might have on the revenue recognition for our retransmission consent agreements as well as our broadcast advertising arrangements. We are also evaluating the impact the new guidance has on our programming barter arrangements.
