The effective tax rate for the three months ended March 31, 2016 differed from the federal statutory rate applied to earnings and losses before income taxes primarily as a result of the mix of earnings and losses and tax rates between tax jurisdictions and changes in valuation allowances.

Additionally, the Company has state net operating loss tax carryforwards in amounts that are comparable to the U.S. NOLs. Real Industry has valuation allowances recorded to reduce certain deferred tax assets to amounts that are more likely than not to be realized. The valuation allowances relate to the potential inability to realize our deferred tax assets associated with U.S. NOLs and certain other foreign jurisdictions.

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 three months ended March 31, 2016 may change in subsequent periods. The effective tax rate for the three months ended March 31, 2016 differed from the federal statutory rate applied to earnings and losses before income taxes primarily as a result of the mix of earnings and losses and tax rates between tax jurisdictions and changes in valuation allowances. The income tax expense for the three months ended March 31, 2016 was $0.7 million, compared to a $7.4 million income tax benefit for the three months ended March 31, 2015.

As of December 31, 2015, the Company has estimated U.S. NOLs of $871.8 million and non-U.S. NOLs of $27.6 million. The U.S. NOLs have a 20-year life and begin to expire after the 2027 tax year. Additionally, the Company has state net operating loss tax carryforwards in amounts that are comparable to the U.S. NOLs. Real Industry has valuation allowances recorded to reduce certain deferred tax assets to amounts that are more likely than not to be realized. The valuation allowances relate to the potential inability to realize our deferred tax assets associated with U.S. NOLs and certain other foreign jurisdictions. Real Industry intends to maintain its valuation allowances until sufficient positive evidence exists to support their reversal.

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.
