Various trading and derivative instruments are used as part of the Company’s overall balance sheet management strategies and to support client requirements executed through the Bank and/or the Company's broker/dealer subsidiary. The Company manages the potential market volatility associated with trading instruments with appropriate risk management strategies. The size, volume, and nature of the trading products and derivative instruments can vary based on economic conditions as well as client-specific and Company-specific asset or liability positions. Product offerings to clients include debt securities, loans traded in the secondary market, equity securities, derivative contracts, and other similar financial instruments. Other trading-related activities include acting as a market maker for certain debt and equity security transactions, derivative instrument transactions, and foreign exchange transactions. The Company also uses derivatives to manage its interest rate and market risk from non-trading activities. The Company has policies and procedures to manage market risk associated with client trading and non-trading activities, and assumes a limited degree of market risk by managing the size and nature of its exposure. For valuation assumptions related to the Company's trading products, as well as additional information on our derivative instruments, see Note 17, “Derivative Financial Instruments,” and the “Trading Assets and Derivative Instruments and Securities Available for Sale” section of Note 18, “Fair Value Election and Measurement.”
