The Company enters into derivative instruments such as futures, options, swaps, forward contracts and other derivative contracts primarily to manage its foreign currency exposure, obtain exposure to a particular financial market, for yield enhancement, or for trading and speculation. The Company accounts for its derivatives in accordance with FASB ASC Topic Derivatives and Hedging, which requires all derivatives to be recorded at fair value on the Company's balance sheet as either assets or liabilities, depending on the rights or obligations of the derivatives, with changes in fair value reflected in current earnings. The Company does not currently apply hedge accounting in respect of any positions reflected in its consolidated financial statements. Where the Company has entered into master netting agreements with counterparties, or the Company has the legal and contractual right to offset positions, the derivative positions are generally netted by counterparty and are reported accordingly in other assets and other liabilities.

The table below shows the location on the consolidated balance sheets and fair value of the Company's principal derivative instruments:

The Company is not aware of the existence of any credit risk-related contingent features that it believes would be triggered in its derivative instruments that are in a net liability position at September 30, 2011.

The Company uses interest rate futures within its portfolio of fixed maturity investments to manage its exposure to interest rate risk, which can include increasing or decreasing its exposure to this risk. At September 30, 2011, the Company had $4.5 billion of notional long positions and $298.0 million of notional short positions of primarily Eurodollar and U.S. Treasury and non-U.S. dollar futures contracts (December 31, 2010 - $2.2 billion and $209.1 million, respectively). The fair value of these derivatives is determined using exchange traded prices.

The Company's functional currency is the U.S. dollar. The Company writes a portion of its business in currencies other than U.S. dollars and may, from time to time, experience foreign exchange gains and losses in the Company's consolidated financial statements. All changes in exchange rates, with the exception of non-U.S. dollar denominated investments classified as available for sale and non-monetary assets and liabilities, are recognized currently in the Company's consolidated statements of operations.

The Company's foreign currency policy with regard to its underwriting operations is generally to hold foreign currency assets, including cash, investments and receivables that approximate the foreign currency liabilities, including claims and claim expense reserves and reinsurance balances payable. When necessary, the Company may use foreign currency forward and option contracts to minimize the effect of fluctuating foreign currencies on the value of non-U.S. dollar denominated assets and liabilities associated with its underwriting operations. The fair value of the Company's underwriting operations related foreign currency contracts is determined using indicative pricing obtained from counterparties or broker quotes. At September 30, 2011, the Company had outstanding underwriting related foreign currency contracts of $123.7 million in notional long positions and $694.2 million in notional short positions, denominated in U.S. dollars (December 31, 2010 - $42.0 million and $188.1 million, respectively).

The Company's investment operations are exposed to currency fluctuations through its investments in non-U.S. dollar fixed maturity investments, short term investments and other investments. To economically hedge its exposure to currency fluctuations from these investments, the Company has entered into foreign currency forward contracts. Foreign exchange gains (losses) associated with the Company's hedging of these non-U.S. dollar investments are recorded in net foreign exchange losses in its consolidated statements of operations. The fair value of the Company's investment portfolio related foreign currency forward contracts is determined using an interpolated rate based on closing forward market rates. At September 30, 2011, the Company had outstanding investment portfolio related foreign currency contracts of $166.4 million in notional long positions and $350.2 million in notional short positions, denominated in U.S. dollars (December 31, 2010 - $69.2 million and $281.0 million, respectively).

The Company's energy and risk operations are exposed to currency fluctuations through certain derivative transactions it enters into that are denominated in non-U.S. dollars. The Company may, from time to time, use foreign currency forward and option contracts to minimize the effect of fluctuating foreign currencies on the value of non-U.S. dollar denominated assets and liabilities associated with these operations. The fair value of the Company's energy and risk operations related foreign currency contracts is based on exchange traded prices. At September 30, 2011, the Company's energy and risk management operations had outstanding foreign currency contracts of $75.0 million in notional long positions and $17.1 million in notional short positions, denominated in U.S. dollars (December 31, 2010 - $Nil and $10.0 million, respectively).

The Company's exposure to credit risk is primarily due to its fixed maturity investments, short term investments, premiums receivable and reinsurance recoverable. From time to time, the Company purchases credit derivatives to hedge its exposures in the insurance industry and to assist in managing the credit risk associated with ceded reinsurance. The Company also employs credit derivatives in its investment portfolio to either assume credit risk or hedge its credit exposure. The fair value of the credit derivatives is determined using industry valuation models, broker bid indications or internal pricing valuation techniques. The fair value of these credit derivatives can change based on a variety of factors including changes in credit spreads, default rates and recovery rates, the correlation of credit risk between the referenced credit and the counterparty, and market rate inputs such as interest rates. At September 30, 2011, the Company had outstanding credit derivatives of $15.0 million in notional long positions and $79.0 million in notional short positions, denominated in U.S. dollars (December 31, 2010 - $15.0 million and $118.0 million, respectively).

The Company regularly transacts in certain derivative-based risk management products primarily to address weather and energy risks and engages in hedging and trading activities related to these risks. The trading markets for these derivatives are generally linked to energy and agriculture commodities, weather and other natural phenomena. Currently, a significant percentage of the Company's derivative-based risk management products are transacted on a dual-trigger basis combining weather or other natural phenomenon, with prices for commodities or securities related to energy or agriculture. The fair value of these contracts is obtained through the use of quoted market prices, or in the absence of such quoted prices, industry or internal valuation models. Generally, the Company's current portfolio of such derivative contracts is of comparably short duration and such contracts are predominantly seasonal in nature. Over time, the Company currently expects that its participation in these markets, and the impact of these operations on its financial results, is likely to increase on both an absolute and relative basis.

The Company had the following gross derivative contract positions outstanding relating to its energy and weather derivatives trading activities.
