Subsequent to the consummation of the Eldorado Merger, the Company's business plan consists primarily of its holding, through AcquisitionCo, of the ERI shares and the Mesquite Interest. See Note 10, "Subsequent Events - Eldorado Transaction," below. Prior to the Eldorado Merger, Eldorado owned entities that own and operate the Eldorado Hotel & Casino located in Reno, Nevada and the Eldorado Resort Casino Shreveport located in Shreveport, Louisiana. Eldorado also owned, through a wholly owned subsidiary, an approximate 21% interest ("the "Tamarack Interest") in a joint venture that owns and operates Tamarack Junction Casino & Restaurant, a small casino located in Reno, Nevada. In addition, Eldorado owned an approximate 96% interest in Eldorado Limited Liability Company, a Nevada limited liability company and subsidiary of Eldorado ("ELLC")which owns a 50% interest in a joint venture (the "Silver Legacy Joint Venture") that owns and operates the Silver Legacy Resort Casino (which is seamlessly connected to the Eldorado Hotel & Casino).

In addition, ERI also owns a 50% interest in the Silver Legacy Resort Casino (a 50/50 joint venture with MGM Resorts International), The six properties contain a combined 3,300 hotel rooms, 280 table games, 32 restaurants, and approximately 10,000 slot machines and video lottery terminals.

Mesquite also owns real estate on which the Oasis Resort & Casino was located prior to its demolition, which was substantially completed by August 31, 2013. The Company holds no equity interests other than the equity interest in ERI evidenced by the ERI shares acquired in exchange for the Eldorado Interest and the Mesquite Interest, along with any indirect interests it may, from time to time, hold in other entities by virtue of its equity interests in ERI and Mesquite. The Company has no current plans to acquire any equity interest in another entity. Formed in 2005, Newport is a Texas-based investment management firm focused on alternative fixed income strategies. The firm concentrates primarily on the stressed and distressed opportunities within the high yield debt and bank loan markets but may also include the acquisition and disposition of other types of corporate securities and claims. Newport has 10 employees, with its primary office in The Woodlands, TX. Newport’s principals include Timothy T. Janszen, CEO, Ryan Langdon, Senior Managing Director, and Roger A. May, Senior Managing Director. Collectively, the principals have over 35 years of experience investing in the high yield and distressed debt markets. Newport is registered with the Securities and Exchange Commission (the "Commission") as an investment adviser under the Investment Advisers Act of 1940, as amended. Newport is investment manager of the Newport Funds, private investment funds which seek attractive long-term risk adjusted returns by capitalizing on investments in the distressed debt markets and possibly control-oriented investments. The Newport Funds began investing in 2006. Concentrations and economic uncertainties The Company is, and expects to continue to be, economically dependent upon relatively few investments in the gaming industry. The United States recently experienced a recession accompanied by, among other things, weakness in the commercial and investment banking systems resulting in reduced credit and capital financing availability, and highly curtailed gaming, other recreational, construction and real estate market activities and general discretionary consumer spending. Although capital market activity and liquidity are reported to have improved of late, the recovery from this recessionary period is fragile and there can be no assurance that the Company’s business, which has been severely affected by the downturn, will fully recover to pre-recession levels. In addition, the Company carries cash on deposit with financial institutions substantially in excess of federally-insured limits. However, the extent of any loss that might be incurred as a result of uninsured deposits in the event of a future failure of a bank or other financial institutions, if any, is not subject to estimate at this time.
