Recent Accounting Pronouncements In 2014, the FASB issued new accounting guidance related to revenue recognition. This new standard will replace all current GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition guidance provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. This guidance can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. In 2015, the FASB issued guidance to defer the effective date to fiscal years beginning after December 15, 2017 with early adoption for fiscal years beginning December 15, 2016. In 2016, the FASB issued additional guidance to clarify the implementation guidance. We are evaluating the impact of adopting the new accounting guidance on our consolidated financial statements. In 2015, the FASB issued new guidance related to presentation of debt issuance costs. The new standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. We adopted this standard retrospectively in the first quarter of 2016. The balance sheet as of December 31, 2015 was retrospectively adjusted, which resulted in reductions to other assets of $30 million and long-term debt of $30 million. In 2016, the FASB issued new guidance related to accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements. In 2016, the FASB issued new guidance related to accounting for leases. The new guidance requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements. In 2016, the FASB issued new guidance to revise aspects of stock-based compensation guidance which include income tax consequences, classification of awards as equity or liabilities, and classification on the statement of cash flows. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements.
