Financial Instruments	Financial Instruments Except for cash and Note Receivable, Newport Funds, the fair value of which equals its carrying value, the only significant financial instruments the Company has are its ERI shares carried at fair value based on trading activity, its investment in Mesquite accounted for using the equity method for which fair value disclosure is not required, and its amounts due to and from the Newport Funds. There is no formal agreement between the Company and the Newport Funds related to the amounts due to the Newport Funds, including no stated right of offset, repayment terms, and interest rate or method. Accordingly, it is not practical to estimate the fair value of such financial instruments.
