TAXES ON INCOME	TAXES ON INCOME For the three months ended March 31, 2018 and 2017, the effective income tax rate was 22.5% and 31.8%, respectively. The lower effective income tax rate was primarily due to the reduced corporate tax rate as a result of the TCJA. In addition, the effective tax rate for the three months ended March 31, 2018 and 2017 benefited from $8 million and $16 million, respectively, of excess tax benefits associated with stock-based compensation arrangements. The Company recognized the income tax effects of the TCJA in its audited consolidated financial statements included in the Company’s 2017 Annual Report on Form 10-K in accordance with Staff Accounting Bulletin No. 118, which provides Securities and Exchange Commission staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in which the TCJA was signed into law. The guidance also provides for a measurement period of up to one year from the enactment date for the Company to complete the accounting for the U.S. tax law changes. As such, the Company’s 2017 financial results reflected the provisional estimate of the income tax effects of the TCJA. No subsequent adjustments have been made to the amounts recorded as of December 31, 2017, which continue to represent a provisional estimate of the impact of TCJA.
