Income Taxes	NOTE 7—INCOME TAXES At the end of each reporting period, Real Industry makes an estimate of its annual effective income tax rate. The estimate used for the six months ended June 30, 2016 may change in subsequent periods. The effective tax rate for the six months ended June 30, 2016 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. The income tax expense for the three months ended June 30, 2016 and 2015 was $0.2 million income tax expense. For the six months ended June 30, 2016, income tax expense was $0.9 million, compared to a $7.2 million income tax benefit for the six months ended June 30, 2015.

The U.S. federal NOLs have a 20-year life and begin to expire after the 2027 tax year. Additionally, the Company has state NOLs in amounts that are comparable to the U.S. federal NOLs. 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 its valuation allowances until sufficient positive evidence exists to support their realization through achieving profitability. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions, as well as foreign jurisdictions located in Canada, Mexico, Germany, Norway, and the United Kingdom.
