Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Sale of ERI stock Subsequent to February 29, 2016, the Company sold its remaining interest in ERI, consisting of 3,554,922 shares of its common stock, and realized a gain of approximately $15.5 million. The aggregate sales price of the shares was approximately $41.4 million. See Note 4 for additional discussion related to the Company's sale of its ERI common stock. Distributions of note receivable Subsequent to February 29, 2016, the Company distributed to the Newport Funds its $4.9 million note receivable from the Newport Funds. Nevada Gaming Regulations The Company was previously required by Nevada gaming regulations to comply with the periodic reporting requirements of the United States Securities and Exchange Commission (the "SEC"). Subsequent to February 29, 2016, Nevada gaming regulations were amended to allow for possible exemption from the SEC reporting requirement. The Company requested and was granted a hearing with the Nevada gaming regulators to determine whether the Company did qualify for the exemption. It was determined during a July 2016 hearing that the Company did qualify for the exemption and subsequently, on October 11, 2016, the Company filed a Form 15 with the SEC to terminate its registration with the SEC and thus its SEC periodic reporting requirements, other than any unfulfilled reporting obligation that became due on or before the date the Form 15 was filed. Accordingly, and, notwithstanding its filing of the Form 15, the Company will be filing a report on Form 10-Q for the quarterly period ended May 31, 2016, which was delayed pending the filing of this amendment to the Company's Form 10-K for the year ended February 29, 2016. Restatement of Financial Statements Subsequent to February 29, 2016, it was determined that the Company’s tax provision for 2016 was misstated. The misstatement related solely to the fourth quarter of 2016 and involved income tax benefits arising from the reversal of valuation allowances that had been misallocated between income tax benefits associated with operations versus other comprehensive income. The restatement increased income tax benefit associated with operations and net income by $3,444,062 and decreased income tax benefits associated with the unrealized gain on marketable securities, net of income taxes, with no effect on total comprehensive income or total member’s equity. Accordingly, accumulated deficit was also decreased by $3,444,062 and accumulated other comprehensive income was decreased by a like amount
