Segment And Geographic Information [Abstract] |
Segment And Geographic Information | 12. Segment and Geographic Information IBG, Inc. operates in two business segments: electronic brokerage and market making. IBG, Inc. conducts its electronic brokerage business through its Interactive Brokers subsidiaries, which provide electronic execution and clearing services to customers worldwide. The Company conducts its market making business principally through its Timber Hill subsidiaries on the world’s leading exchanges and market centers, primarily in exchange‑traded equities, equity options and equity‑index options and futures. Significant transactions and balances between the Operating Companies occur, primarily as a result of certain Operating Companies holding exchange or clearing organization memberships, which are utilized to provide execution and clearing services to affiliates. Charges for transactions between segments are designed to approximate full costs. Intra‑segment and intra‑region income and expenses and related balances have been eliminated in this segment and geographic information to reflect the external business conducted in each segment or geographical region. Corporate items include non‑allocated corporate income and expenses that are not attributed to segments for performance measurement, corporate assets and eliminations. Management believes that the following information by business segment provides a reasonable representation of each segment’s contribution to total net revenues and income before income taxes for the three months ended June 30, 2014 and 2013, and to total assets as of June 30, 2014 and December 31, 2013 (millions):
