Leases [Abstract] |
Lessee, Operating Leases [Text Block] | 20: LEASES ASU 2016-02, Leases (Topic 842) and its related amendments (collectively, the New Lease Accounting Standard) are effective for reporting periods beginning after December 15, 2018. We adopted the New Lease Accounting Standard effective January 1, 2019 and elected the modified retrospective approach in which results for periods before 2019 were not adjusted for the new standard and the cumulative effect of the change in accounting was recognized through retained earnings at the date of adoption. We have elected certain of the practical expedients available under the New Lease Accounting Standard. We have applied the practical expedient which allows prospective transition to the New Lease Accounting Standard on January 1, 2019. Under the transition practical expedient, we did not reassess lease classification, embedded leases or initial direct costs. We have applied the practical expedient for short-term leases. We have lease agreements with lease and non-lease components. We have elected the practical expedients to combine these components for certain equipment leases. Additionally, for certain equipment leases, we apply a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities. The adoption of the New Lease Accounting Standard did not have a material effect on our Consolidated Statement of Operations or Consolidated Statement of Cash Flows. Upon adoption, we recorded a $1.7 billion right-of-use asset and a $1.7 billion lease liability. The adoption of the New Lease Accounting Standard had an immaterial impact on retained earnings. Operating lease expense for the year ended December 31, 2019 was approximately $323 million. Supplemental cash flow information related to operating leases was as follows:
(dollars in millions) | Year ended December 31, 2019
Operating cash flows used in the measurement of operating lease liabilities | $ | 411 |
Operating lease right-of-use assets obtained in exchange for operating lease obligations | 123 |
