Securities and Commodity Financing Transactions Securities and Commodity Financing Transactions
The Company’s repurchase agreements and securities borrowing and lending arrangements are generally recorded at cost in the Condensed Consolidated Balance Sheets, which is a reasonable approximation of their fair values due to their short-term nature. Secured borrowing and lending arrangements are entered into to obtain collateral necessary to effect settlement, finance inventory positions, meet customer needs or re-lend as part of our dealer operations. The fair value of securities loaned and borrowed is monitored daily compared with the related payable or receivable, and additional collateral or returning excess collateral is requested, as appropriate. These arrangements may serve to limit credit risk resulting from transactions with counterparties. Financial instruments are pledged as collateral under repurchase agreements, securities lending agreements and other secured arrangements, including clearing arrangements. Agreements with counterparties generally contain contractual provisions allowing counterparties the right to sell or repledge collateral. Either the Company or its counterparties may require additional collateral. All collateral is held by the Company or a custodian.
The following tables set forth the carrying value of repurchase agreements, and securities lending agreements by remaining contractual maturity (in millions):

The Company pledges securities owned as collateral in both tri-party and bilateral arrangements. Pledged securities under tri-party arrangements may not be repledged or sold by the Company’s counterparties, whereas bilaterally pledged securities may be. The approximate fair value of pledged securities that can be sold or repledged by the Company’s counterparties has been parenthetically disclosed on the Condensed Consolidated Balance Sheets.
The Company receives securities as collateral under reverse repurchase agreements, securities borrowed agreements, and margin securities held on behalf of counterparties. This collateral is used by the Company to cover financial instruments sold, not yet purchased; to obtain financing in the form of repurchase agreements; and to meet counterparties’ needs under lending arrangement and matched-booked trading strategies. Additional securities collateral is obtained as necessary to ensure such transactions are adequately collateralized. In many instances, the Company is permitted by contract to repledge the securities received as collateral, which may include pledges to cover collateral requirements for tri-party repurchase agreements.
The following table sets forth the fair values, which approximates carrying value because of the short term nature of collateral pledged, received and repledged (in millions):
