Income Taxes	13. INCOME TAXES The Company calculates its provision for federal and state income taxes based on current tax law. The Tax Cuts and Jobs Act (tax reform) was enacted on December 22, 2017 (“Enactment Date”), and has several key provisions impacting accounting for and reporting of income taxes. The most significant provision reduces the U.S. corporate statutory tax rate from 35% to 21% beginning on January 1, 2018. Although most provisions of tax reform are not effective until 2018, the Company is required to record the effect of a change in tax law as of the Enactment Date on its deferred tax assets. As the Company maintains a full valuation allowance against its deferred tax assets, there is no income tax expense recorded related to this change. As of the Enactment Date, the Company estimated that its deferred tax asset and related valuation allowance were each reduced by approximately $2.2 million.

While we are able to make reasonable estimates of the impact of the reduction in corporate rate and the deemed repatriation transition tax, the final impact of the Tax Act may differ from these estimates, due to, among other things, changes in our interpretations and assumptions, additional guidance that may be issued by the I.R.S., and actions we may take.
