Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Subsequent to year-end, on December 1, 2021, Jefferies transferred certain investments in securities and limited partnerships to us. In addition, also on December 1, 2021, Jefferies transferred its investment in Foursight Capital, a subsidiary of Jefferies, to us. These transfers were accomplished as capital contributions from Jefferies, and since we are under common control, these capital contributions were recorded at their book values. As a result of these transfers, our total assets increased by $1.27 billion, total liabilities increased by $800.4 million and total equity increased by $476.5 million in our Consolidated Statement of Financial Condition at December 1, 2021.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
