In the normal course of operations, the Company enters into derivative contracts. These derivative contracts primarily consist of foreign exchange swaps, foreign exchange/commodities options, futures and forwards. The Company enters into derivative contracts to facilitate client transactions, hedge principal positions and facilitate hedging activities of affiliated companies.

Derivative contracts can be exchange-traded or OTC. Exchange-traded derivatives typically fall within Level 1 or Level 2 of the fair value hierarchy depending on whether they are deemed to be actively traded or not. The Company generally values exchange-traded derivatives using their closing prices. OTC derivatives are valued using market transactions and other market evidence whenever possible, including market-based inputs to models, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. For OTC derivatives that trade in liquid markets, such as forwards, swaps and options, model inputs can generally be verified and model selection does not involve significant management judgment. Such instruments are typically classified within Level 2 of the fair value hierarchy.

The Company does not designate any derivative contracts as hedges for accounting purposes. U.S. GAAP guidance requires that an entity recognize all derivative contracts as either assets or liabilities in the unaudited condensed consolidated statements of financial condition and measure those instruments at fair value. The fair value of all derivative contracts is recorded on a net-by-counterparty basis where a legal right to offset exists under an enforceable netting agreement. Derivative contracts are recorded as part of “Receivables from broker-dealers, clearing organizations, customers and related broker-dealers” and “Payables to broker-dealers, clearing organizations, customers and related broker-dealers” in the Company’s unaudited condensed consolidated statements of financial condition.

The fair value of derivative contracts, computed in accordance with the Company’s netting policy, is set forth below (in thousands):
