Overseas Shipholding Group, Inc. provides tax rate guidance for the fourth quarter of the fiscal year ended December 31, 2017. The company announced that, based on current estimates, it expects to recognize a one-time non-cash tax benefit of approximately $40.0 million in the fourth quarter of the fiscal year ended December 31, 2017. This estimated tax benefit is based on the Company's preliminary assessment of the impact of the recently passed federal tax reform legislation (commonly known as the Tax Cuts and Jobs Act of 2017), which reduced the federal corporate income tax rate from 35.0% to 21.0%.
