New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING GUIDANCE	RECENT ACCOUNTING GUIDANCE Recently Adopted Accounting Guidance In the first quarter of 2019, the Corporation adopted ASU 2016-02, "Leases (Topic 842)," and associated ASUs related to Topic 842, which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance requires that a lessee recognize assets and liabilities for leases, and recognition, presentation and measurement in the financial statements will depend on its classification as a finance or operating lease. In addition, the new guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from legacy U.S. GAAP but does contain some targeted improvements to align with revenue recognition guidance Topic 606, "Revenue from Contracts with Customers." The new standard was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, and early adoption was permitted. The Corporation adopted Topic 842 using the modified retrospective transition approach, applying the new standard to leases existing at the date of initial adoption. The Corporation elected to apply the transition requirements at the effective date rather than at the beginning of the earliest comparative period presented with a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption, and prior periods were not restated. In addition, the Corporation elected to apply the package of practical expedients permitted under the transition guidance which does not require reassessment of prior conclusions, lease classification and initial direct lease costs. The Corporation did not elect to use the hindsight practical expedient in determining the lease term or assessing impairment of ROU assets. Adoption of the new standard resulted in the recording of lease assets and liabilities of $99 million at January 1, 2019. The difference between the additional lease assets and lease liabilities, net of deferred taxes, was recorded as an adjustment to retained earnings and was not material. The adoption of the new guidance did not have a material impact on the Corporation's consolidated statements of income and had no impact on cash flows. See Note 9 for additional information.

Recently Adopted Accounting Guidance

In the first quarter of 2019, the Corporation adopted ASU 2016-02, "Leases (Topic 842)," and associated ASUs related to Topic 842, which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases.

In addition, the new guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from legacy U.S. GAAP but does contain some targeted improvements to align with revenue recognition guidance Topic 606, "Revenue from Contracts with Customers."
