Income Taxes

The Company has certain subsidiaries that have elected to be treated as corporations for U.S. federal income tax purposes. As of December 31, 2017 one such subsidiary had a deferred tax asset, resulting from a net operating loss carryforward, which was fully reserved through a valuation allowance. As of December 31, 2017, the deferred tax asset and the valuation allowance were valued at $4.0 million and $(4.0) million, respectively. New tax reform legislation enacted in late 2017 reduces the federal corporate income tax rate from 35% to 21%, effective January 1, 2018. This had the effect of reducing both the deferred tax asset and the valuation allowance from their values prior to the enactment.
