The Company may apply this ASU at the beginning of the period of adoption or retrospectively to all periods in which the 2017 Tax Act is enacted. January 1, 2019 Early adoption is permitted. The Company early adopted this ASU beginning January 1, 2018. Upon adoption of this ASU, the Company elected to reclassify $182 million of stranded tax effects relating to securities AFS, derivative instruments, credit risk on long- term debt, and employee benefit plans fromAOCI to retained earnings. This amount was offset by $28 million of stranded tax effects relating to equity securities previously classified as securities AFS, resulting in a net $154 million increase to retained earnings. ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans This ASU amends ASC Subtopic 715-20, Compensation - Retirement Benefits - Defined Benefit Plans - General , to add new disclosure requirements as well as remove certain disclosure requirements to improve the effectiveness of disclosures in the notes to the financial statements. TheASUmust be applied on a retrospective basis. December 31, 2020 Early adoption is permitted. The Company early adopted this ASU beginning December 31, 2018 and modified its employee benefit plans disclosures accordingly for each of the years ended December 31, 2018, 2017, and 2016. The adoption of this ASU did not have an impact on the Company’s Consolidated Financial Statements. See Note 17, “Employee Benefit Plans,” for the Company’s employee benefit plans disclosures. Standards Not Yet Adopted ASU 2016-02, Leases (ASC Topic 842) and subsequent related ASUs This ASU creates ASC Topic 842, Leases , which supersedes ASC Topic 840, Leases . ASC Topic 842 requires lessees to recognize right-of-use assets and associated liabilities that arise from leases, with the exception of short-term leases. The ASU does not make significant changes to lessor accounting; however, there were certain improvements made to align lessor accounting with the lessee accounting model and ASC Topic 606, Revenue from Contracts with Customers . There are several new qualitative and quantitative disclosures required. Upon transition, lessees and lessors have the option to: - Recognize and measure leases at the beginning of the earliest period presented using a modified retrospective transition approach, or - Apply a modified retrospective transition approach as of the date of adoption. January 1, 2019 Early adoption is permitted. The Company formed a cross-functional team to oversee the implementation of this ASU. The Company’s implementation included the review of its lease portfolios and related lease accounting policies, the review of its service contracts for embedded leases, and the deployment of a new lease software solution. Additionally, in conjunction with this implementation, theCompany reviewed its business processes and evaluated changes to its control environment. The Company adopted this ASU on January 1, 2019, using a modified retrospective transition approach as of the date of adoption, which resulted in an increase in right-of-use assets and associated lease liabilities, arising from operating leases in which the Company is the lessee, on its Consolidated Balance Sheets. The amount of the right-of-use assets and associated lease liabilities recorded upon adoption was based primarily on the present value of unpaid future minimum lease payments, the amount of which is based on the population of leases in effect at the date of adoption. At January 1, 2019, the Company’s right-of-use assets and lease liabilities recorded on its Consolidated Balance Sheets upon adoption were $1.2 billion and $1.3 billion, respectively. Upon adoption on January 1, 2019, the Company also recognized a cumulative effect adjustment of $31 million to increase the beginning balance of retained earnings (as of January 1, 2019) for remaining deferred gains on sale- leaseback transactions that occurred prior to the date of adoption and for other transition provisions. This ASU is not expected to have a material impact on the timing of expense recognition in its Consolidated Statements of Income. The Company is in the process of developing and completing the required leasing disclosures, which will be included in its first quarter of 2019 Quarterly Report on Form 10-Q.
