Equity interest percentage   40.00%        
Investment in affiliate description  
The Company owned an interest of 40% (the Company returned its interest in Nottingham effective April 1, 2017. Refer to Note 16, Subsequent Events, for further detail). Management determined that Nottingham was a VIE because it met the following criteria: (i) the entity had insufficient equity to finance its activities without additional subordinated financial support from other parties and the 60% owner guaranteed its debt, (ii) the voting rights of the Company were not proportional to their obligations to absorb the expected losses of the legal entity, and (iii) substantially all of the legal entity’s activities either involved or were conducted on behalf of an investor that had disproportionately few voting rights. The Company had the ability to exercise its call option to acquire the remaining 60% of Nottingham.
