Regulated Operations [Abstract] |
Regulatory Requirements | Regulatory requirements The Company's U.S. broker dealer subsidiaries, Oppenheimer and Freedom, are subject to the uniform net capital requirements of the SEC under Rule 15c3-1 (the "Rule") promulgated under the Securities Exchange Act of 1934. Oppenheimer computes its net capital requirements under the alternative method provided for in the Rule which requires that Oppenheimer maintain net capital equal to two percent of aggregate customer-related debit items, as defined in SEC Rule 15c3-3. As of December 31, 2017, the net capital of Oppenheimer as calculated under the Rule was $142.0 million or 14.00% of Oppenheimer's aggregate debit items. This was $121.7 million in excess of the minimum required net capital at that date. Freedom computes its net capital requirement under the basic method provided for in the Rule, which requires that Freedom maintain net capital equal to the greater of $100,000 or 6-2/3% of aggregate indebtedness, as defined. As of December 31, 2017, Freedom had net capital of $5.3 million, which was $5.2 million in excess of the $100,000 required to be maintained at that date.
