Counsel Loan, Description					The Company’s Related Party Debt (the “Street Capital Loan”), which is due on demand, was originally entered into in 2003 and accrued interest at 10% per annum compounded quarterly from the date funds were advanced. The Street Capital Loan is secured by the assets of the Company. In the second quarter of 2014, following Street Capital’s distribution of its ownership interest in HGI to Street Capital shareholders as a dividend in kind, the unpaid balance of the Street Capital Loan began accruing interest at a rate per annum equal to the lesser of the Wall St. Journal (“WSJ”) prime rate + 2.0%, or the maximum rate allowable by law. As of December 31, 2015 and 2014, the interest rate on the loan was 5.50% and 5.25%, respectively.
