On Assignment, Inc. revised earnings guidance for the fourth quarter of 2017. The company announced that it expects to record in the fourth quarter of 2017 a one-time, non-cash income tax benefit of $30.5 million to $33.5 million ($0.58 to $0.64 per diluted share) as a result of the recently enacted Tax Cuts and Jobs Act (TCJA). The income tax benefit is mainly the result of the revaluation of net deferred income tax liabilities and an estimate of the transitional tax on deemed repatriated foreign earnings. As a result of this one-time income tax benefit, financial estimates for net income and Adjusted Net Income (a non-GAAP measure) and related per share amounts have been updated for the fourth quarter of 2017. Net income estimate is now $61.4 to $66.2 million (compared with previously-announced estimate of $30.9 million to $32.7 million), and earnings per diluted share estimate is now $1.17 to $1.26 (compared with previously-announced estimate of $0.59 to $0.62). Adjusted Net Income (a non-GAAP measure) estimate is now $69.4 million to $74.1 million (compared with previously-announced estimate of $38.9 million to $40.6 million), and Adjusted Net Income per diluted share estimate is now $1.32 to $1.41 (compared with previously-announced estimate of $0.74 to $0.77). While the company expects subsequent regulations and interpretations associated with the TCJA to be released that will provide additional guidance on application of the law, the company currently estimates its effective tax rate for 2018 will range between 25.5% and 27.5%.
