New Accounting Pronouncements Leases In February 2016, the FASB established Topic 842, Leases, by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10 and ASU No. 2019-01, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. We adopted the new standard effective January 1, 2019 using a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial application. An entity was permitted to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. If an entity chooses the second option, the transition requirements for existing leases also apply to leases entered into between the date of initial application and the effective date. The entity must also recast its comparative period financial statements and provide the disclosures required by the new standard for the comparative periods. Consequently, financial information was not updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. The new standard provided a number of optional practical expedients in transition. We elected the ‘package of practical expedients’, which permitted us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We elected the practical expedient pertaining to land easements. We also elected the short-term lease recognition exemption for certain of our vehicle agreements. This means, for those leases that qualify, we will not recognize ROU assets or lease liabilities. Upon adoption, we recognized additional operating liabilities of $1.2 billion, with corresponding ROU assets of the same amount based on the present value of the remaining minimum rental payments under current leasing standards for our existing operating leases. In addition to the increase to the operating lease liabilities and right-of-use assets, Topic 842 also resulted in reclassifying the presentation of prepaid and deferred rent to operating lease right-of-use assets. The Company did not have any changes to its opening balance of retained earnings for the adoption of this update.

The update simplifies how a company completes its goodwill impairment test by eliminating the two-step process, which requires determining the fair value of assets acquired or liabilities assumed in a business combination. The update requires completing the goodwill impairment test by comparing the difference between the reporting unit’s carrying value and fair value. Goodwill charges, if any, would be determined by reducing the goodwill balance by the excess of the reporting unit’s carrying value over its fair value. The update is effective for annual and interim fiscal periods beginning after December 15, 2019, with early adoption permitted for interim or annual goodwill impairment tests performed on or after January 1, 2017. The Company adopted this update beginning with its December 31, 2017 goodwill impairment test. In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808). The update is to clarify when certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 and when the collaborative arrangement participant is a customer in the context of a unit of account. The update also adds unit-of-account guidance in Topic 808 and requires that a collaborative arrangement participant that is not directly related to sales to a third party, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer. The update is effective for annual and interim fiscal periods beginning after December 15, 2019 with early adoption permitted. The Company does not believe this update will have a material effect on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments, and additional changes modifications, clarifications, or interpretations related to this guidance thereafter, which require a reporting entity to estimate credit losses on certain types of financial instruments, and present assets held at amortized cost and available-for-sale debt securities at the amount expected to be collected. The new guidance is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its Consolidated Financial Statements.

13. New Accounting Pronouncements

Leases

In February 2016, the FASB established Topic 842, Leases, by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10 and ASU No. 2019-01, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance

sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement.

We adopted the new standard effective January 1, 2019 using a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial application. An entity was permitted to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. If an entity chooses the second option, the transition requirements for existing leases also apply to leases entered into between the date of initial application and the effective date. The entity must also recast its comparative period financial statements and provide the disclosures required by the new standard for the comparative periods. Consequently, financial information was not updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019.

The new standard provided a number of optional practical expedients in transition. We elected the ‘package of practical expedients’, which permitted us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs.
