Income tax adjustments. For purposes of internal forecasting, planning and analyzing future periods that assume net income from operations, the Company estimates a fixed, long-term projected tax rate of approximately 35 percent for both 2017 and 2016, and 24 percent for 2018 which consists of estimated U.S. federal and state tax rates, and excludes tax rates associated with certain items such as withholding tax, tax credits, deferred tax asset valuation allowance and the release of any deferred tax asset valuation allowance. Accordingly, the Company has applied these tax rates to its non-GAAP financial results for all periods in the relevant years to assist the Company’s planning. The Company has provided below a reconciliation of its GAAP provision for income taxes and GAAP effective tax rate to the assumed non-GAAP provision for income taxes and non-GAAP effective tax rate.

On occasion in the future, there may be other items, such as significant gains or losses from contingencies that the Company may exclude in deriving its non-GAAP financial measures if it believes that doing so is consistent with the goal of providing useful information to investors and management.
