Income Taxes	NOTE 8—INCOME TAXES At the end of each reporting period, Real Industry estimates its annual effective income tax rate. The estimate used for the three months ended March 31, 2017 may change in subsequent periods. The effective tax rate for the three months ended March 31, 2017 differed from the federal statutory rate applied to earnings and losses before income taxes primarily as a result of the mix of earnings, losses, and tax rates between tax jurisdictions, and changes in valuation allowances.

Real Industry has valuation allowances recorded to reduce certain deferred tax assets to amounts that are more likely than not to be realized. Real Industry intends to maintain those valuation allowances until sufficient positive evidence exists to support their realization through achieving profitability.
