Business and Operations	NOTE 1—BUSINESS AND OPERATIONS Real Industry, Inc. (“Real Industry,” the “Company,” “we,” “us” or “our”), formerly known as Signature Group Holding, Inc., is a Delaware holding company that operates through its operating subsidiaries. Management expects to grow the Company through acquisitions, as well as through organic efforts within existing operations described below. Our current business strategy seeks to leverage our public company status, considerable United States (“U.S.”) federal net operating tax loss carryforwards (“NOLs”) and the experience of our executive management team to acquire operating businesses at prices and on terms that are aligned with our growth plans. During the first quarter of 2015, the Company underwent a considerable transformation. On January 9, 2015, we completed the sale of North American Breaker Co., LLC (“NABCO”), previously the primary business within our former Industrial Supply segment. On February 27, 2015, we acquired the global recycling and specification alloys business (the “Real Alloy Business”) of Aleris Corporation (“Aleris”) (the “Real Alloy Acquisition”). A portion of the proceeds of the sale of NABCO were used to fund the Real Alloy Acquisition. The Real Alloy Business, operating as Real Alloy Holding, Inc. (“Real Alloy”), is a global leader in third-party aluminum recycling, which includes the processing of scrap aluminum and by-products and the manufacturing of wrought, cast and specification or foundry alloys. Real Alloy offers a broad range of products and services to wrought alloy processors, automotive original equipment manufacturers, and foundries and casters. Real Alloy’s customers include companies that participate in or sell to the automotive, consumer packaging, aerospace, building and construction, steel, and durable goods industries. Real Alloy processes aluminum scrap and by-products and delivers recycled metal in liquid or solid form according to customer specifications. Real Alloy’s facilities are capable of processing industrial (new) scrap, post-consumer (old/obsolete) scrap, and various aluminum by-products, providing a great degree of flexibility in reclaiming high-quality recycled aluminum. Real Alloy currently operates twenty-seven facilities strategically located throughout North America and Europe. On November 1, 2016 Real Alloy completed the purchase of select assets of Beck Aluminum Alloys. The Beck Aluminum Alloys facilities primarily produce high-purity foundry alloys from aluminum scrap to supply the automotive, wheel and recreational equipment casting industries. Our focus is supporting the performance of Real Alloy, as well as evaluating potential acquisition targets. We seek to acquire significant ownership interests in businesses with talented and experienced management teams, strong margins, and sustainable competitive advantages. We regularly consider acquisitions of businesses that operate in undervalued industries, as well as businesses we believe are in transition or are otherwise misunderstood by the marketplace. Post-acquisition, we plan to operate our businesses as autonomous subsidiaries. We anticipate that we will continue to use our securities to pursue value-enhancing acquisitions and leverage our considerable tax assets, as well as support the growth needs of our existing operating segments, as necessary. The assets and liabilities and results of operations of NABCO are included in discontinued operations for all periods presented as a result of its sale in the first quarter of 2015, and the Company’s strategic shift in operations. Discontinued operations also includes certain assets and liabilities related to the former businesses of our subsidiary, SGGH, LLC (“SGGH”), then known as Fremont General Corporation (“Fremont”) and its primary operating subsidiary, Fremont Investment & Loan (“FIL”). See Note 19—Discontinued Operations for additional information about NABCO and other discontinued operations.
