During the nine months ended September 30, 2019, the Company’s effective income tax rate decreased primarily due to the Global Intangible Low-Taxed Income (“GILTI”) provision of the Tax Reform Act. The Company’s effective income tax rate was also affected by excess tax benefits from stock-based compensation and an increase in U.S. research and development tax credits.
