The clearing houses clear and guarantee the settlement of contracts traded in their respective markets. At December 31, 2012, the operations of KCBTCC were separate from CME, but KCBTCC will be fully integrated with CME Clearing during 2013. In their guarantor roles, the clearing houses have precisely equal and offsetting claims to and from clearing firms on opposite sides of each contract, standing as an intermediary on every contract cleared. Clearing firm positions in the United States are held according to Commodity and Futures Trading Commission (CFTC) regulatory account segregation standards. To the extent that funds are not otherwise available to satisfy an obligation under the applicable contract, the clearing houses bear counterparty credit risk in the event that future market movements create conditions that could lead to clearing firms failing to meet their obligations to the clearing houses. The clearing houses reduce the exposure through risk management programs that include initial and ongoing financial standards for designation as a clearing firm, performance bond requirements and mandatory guaranty fund contributions. Each CME and KCBTCC clearing firm is required to deposit and maintain balances in the form of cash, U.S. Government securities, certain foreign government securities, bank letters of credit or other approved investments to satisfy performance bond and guaranty fund requirements. Clearing firms that clear through CMECE are required to deposit and maintain collateral in the form of cash, certain U.S. and foreign government securities or other approved investments to satisfy performance bond and guaranty fund requirements. All non-cash deposits are marked to market and haircut on a daily basis.</font></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In addition, the rules and regulations of CBOT require that collateral be provided for delivery of physical commodities, maintenance of capital requirements and deposits on pending arbitration matters. To satisfy these requirements, clearing firms that have accounts that trade certain CBOT products have deposited cash, U.S. Treasury securities and letters of credit. </font></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The clearing houses mark-to-market open positions at least twice a day, and require payment from clearing firms whose positions have lost value and make payments to clearing firms whose positions have gained value. For select cleared-only markets, positions are marked-to-market once daily, with the capability to mark-to-market more frequently as market conditions warrant. </font></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Under the extremely unlikely scenario of simultaneous default by every clearing firm who has open positions with unrealized losses, the maximum exposure related to positions other than over-the-counter credit default and interest rate swap contracts would be one half day of changes in fair value of all open positions, before considering the clearing houses' ability to access defaulting clearing firms' collateral deposits. For CME's cleared over-the-counter credit default swap and interest rate swap contracts, the maximum exposure related to CME's guarantee would be one full day of changes in fair value of all open positions, before considering CME's ability to access defaulting clearing firms' collateral. During </font><font style="font-family:Times New Roman;font-size:10pt;color:#000000;text-decoration:none;">2012</font><font style="font-family:inherit;font-size:10pt;">, the clearing houses transferred an average of approximately </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$2.4 billion</font><font style="font-family:inherit;font-size:10pt;"> a day through their clearing systems for settlement from clearing firms whose positions had lost value to clearing firms whose positions had gained value. The clearing houses reduce the guarantee exposure through initial and maintenance performance bond requirements and mandatory guaranty fund contributions.

The performance bond deposits are held jointly by CME and OCC (note 15).

In addition, CME has cross-margin agreements with Fixed Income Clearing Corporation (FICC) whereby the clearing firms' offsetting positions with CME and FICC are subject to reduced performance bond requirements. Clearing firms maintain separate performance bond deposits with each clearing house, but depending on the net offsetting positions between CME and FICC, each clearing house may reduce that firm's performance bond requirements. </font></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Each CME clearing firm for futures and options is required to deposit and maintain specified guaranty fund contributions in the form of cash or approved securities.

The funds for over-the-counter credit default and interest rate swaps are independent of the base guaranty fund and are isolated to clearing firms for products in the respective asset class. Each clearing firm for cleared over-the-counter credit default swaps and cleared over-the-counter interest rate swaps is required to deposit and maintain specified guaranty fund contributions in the form of cash or approved securities. In the event that performance bonds, guaranty fund contributions and other assets required to support clearing membership of a defaulting clearing firm for cleared over-the-counter credit default swap contracts are inadequate to fulfill that clearing firm's outstanding financial obligation, the credit default swaps contracts guaranty fund is available to cover potential losses after first utilizing corporate contributions designated by CME to be used in the event of default of a cleared over-the-counter credit default swap clearing firm, which is equal to the greater of </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$50.0 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">5%</font><font style="font-family:inherit;font-size:10pt;"> of the credit default swap guaranty fund, up to a maximum of </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$100.0 million</font><font style="font-family:inherit;font-size:10pt;">.

CMECE will begin offering to clear interest rate swap contracts in the first quarter of 2013. In the unlikely event of default by a CMECE clearing firm, the company will first apply assets of the defaulting clearing firm to satisfy its payment obligations. If the default remains unsatisfied, the company will apply guaranty fund contributions of </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$52.5 million</font><font style="font-family:inherit;font-size:10pt;"> for interest rate swap clearing firms that will be contributed by CMECE instead of by the clearing firms. In the future, the interest rate swap clearing firms may be asked to contribute to the interest rate swap guaranty fund.
