Great Western Bancorp, Inc. provided effective tax rate guidance for the fiscal year 2018. On December 22, 2017 the Tax Cuts and Jobs Act of 2017 was signed into law, which, among other items, reduces the corporate income tax rate from 35% to 21%. As a result, Great Western Bancorp, Inc. has concluded that this will cause the Company's deferred taxes to be revalued as of the date of enactment of the Act. The revaluation will result in a non-recurring charge to provision for income taxes of approximately $13.6 million for the quarter ended December 31, 2017. The downward revaluation of the deferred taxes is estimated to reduce tangible book value per share by $0.23 or 1.3% based on common shares outstanding as of December 31, 2017 and to reduce the total risk based capital ratio by approximately 15 basis points. In addition, because the Company's fiscal year ends on September 30, the blended federal statutory tax rate for fiscal year 2018 will be 24.5%, which becomes effective for the company's financial results for the quarter ended December 31, 2017. The overall effective tax rate is expected to be approximately 26.0% for the 2018 fiscal year.
