The effective tax rate for the three and six months ended June 30, 2017 differs from the US statutory tax rate of 35% due to the release of the valuation allowance related to net deferred tax assets in the U.S. tax jurisdiction. There were a series of tax adjustments as a result of the settlement with Dow that resulted in $40.0 million additional U.S. deferred tax liabilities. The reductions of Dow’s obligations on the balance sheet impacted purchase price consideration, ultimately decreasing the Company’s intangible’s tax basis determined for ASC 740 purposes. The Company considered these future sources of taxable income as additional positive evidence when concluding the deferred tax assets within the U.S. were more likely than not to be realized and reversed a valuation allowance of $15.4 million at June 30, 2017.
