KFORCE INC. ANNOUNCED ESTIMATED IMPACT OF NEW U.S. TAX LAW ON FOURTH QUARTER 2017 GUIDANCE





TAMPA, FL - Friday, December 29, 2017 - Kforce Inc. (NASDAQ: KFRC) today announced that it expects to record a one-time, non-cash charge in the fourth quarter of 2017 as a result of the recently enacted Tax Cuts and Jobs Act (TCJA). This charge results solely from the revaluation of our net deferred income tax assets as of December 31, 2017 and was not anticipated in our previously announced guidance of $0.41 to $0.43 per share. The negative impact to net income from the revaluation is estimated to be between $6 million to $7 million, or approximately $0.24 to $0.28 per share.


Kforce anticipates subsequent regulations and interpretations to be released associated with TCJA that will provide additional guidance on the application of the law; however, we currently estimate that Kforce’s effective income tax rate will be in the range of 25.5% to 27.5% for 2018 compared to approximately 38.0% for 2017.
